DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

In order to make the technical features, the propose and the technical effect of the present application more clearly, the specific implemental means of the present application will now be described in detail with reference to the accompanying drawings.

FIGS. 3-7 schematically show a magazine according to a preferred embodiment of the present application. In this case, the magazine is used in a pistol. However, it is also possible to use this magazine into any apparatus which needs gas supply.

As is shown in FIGS. 3-7, the magazine of the present application substantially includes a gas bottle 100, a gas bottle holder 200 for holding the gas bottle 100, and a piercing device 300. In this case, the gas bottle 100 is held or received in the gas bottle holder 200 and has high-pressure gas, such as compressed air, stored therein. The gas bottle 100 is generally made from steel, and has a sealing membrane 110 sealed at a mouth (not labeled) of thereof. The sealing member 110 is configured for sealing the gas bottle 100 and retaining the high-pressure gas in the gas bottle 100. The sealing membrane 110 is preferably made from metal.

As is specifically shown in FIGS. 3-7, the gas bottle holder 200 includes a holding casing 210 having a holding cavity 220 defined therein. The gas bottle 100 is held in the holding cavity 220. In this case, it is preferably that the gas bottle 100 is abutted against an inner wall of the holding casing 210.

Furthermore, an opening 230 is formed at one end of the holding casing 210. The piercing device 300 is provided at the opening 230 of the gas bottle holder 200 for sealing the gas bottle holder 200. In addition, the piercing device 300 is movable along a longitudinal axis L1 of the gas bottle holder 200 in such a way that the sealing membrane 110 of the gas bottle 100 can be pierced by the piercing device 300, and thus the gas can escape from the gas bottle 100 and further enters the holding cavity 220 of the gas bottle holder 200 before the magazine is applied into a pistol.

FIGS. 1-2 specifically show the structure of the piercing device 300. As is further shown in FIGS. 1-2, the piecing device 300 includes a housing 310 which is movable along the longitudinal axis L1 of the gas bottle holder 200, a stressing element 320 which is synchronously rotatable along with the housing or individually rotatable and movable with respect to the housing 310, and a piercing element 330 received in the housing 310 and fixed on the stressing element 320.

Here, “synchronously rotatable” means that the stressing element 320 seems to be integrated with the housing 310 at this time, and thus the position of the stressing element 320 and that of the housing 310 are changed synchronously. However, “individually rotatable and movable” means that, the stressing element 320 is separated from the housing 310, and is rotated and moved such that the position of the stressing element 320 is changed while the housing 310 is fixed.

The housing 310 in this case is substantially in shape of a hollow cylinder, and includes a first end 311 and a second end 312 opposite to the first end 311. As is shown in FIGS. 1-3, the first end 311 is the end of the housing 310 that is close to the gas bottle 100 when the piercing device 300 is sealed at the opening 230 of the gas bottle holder 200. That is, the first end 311 is received in the holding cavity 220, while the second end 312 stays outside the gas bottle holder 200 in such a way that a user may operate the piercing device 300 via the second end 312. A through-hole 313 is further defined substantially in the middle of the housing 310, and thus the stressing element 320 may be received in the through-hole 313 of the housing 310.

Furthermore, a first recess 314 is further defined at the second end 312 of the housing 310 that is away from the gas bottle. A driving element (not shown) is capable of being inserted into the first recess 314, in order to drive the housing 310 to move with respect to the gas bottle holder 200.

In this case, as is shown in FIGS. 1-2, an external thread 340 is further formed on an outer wall of the housing 310. Correspondingly, an internal thread (not shown) adapted to the external thread 340 on the outer wall the housing 310 is further formed on the inner wall of the holding casing 210. In this way, the piercing device 300 may be screwed onto the gas bottle holder 200, and the opening 230 of the holding casing 210 is sealed by the piercing device 300 as a result.

In this case, as is shown in FIGS. 1-2 and combing with FIG. 3, a first stopping portion 240 is formed on the inner wall of the holding casing 210; the first stopping portion 240 is configured for limiting a position of the piercing device 300. In this case, the first stopping portion 240 is a stopping step.

Correspondingly, a second stopping portion 350 is provided at the first end 311 of the housing 310 that is close to the gas bottle 100. The second stopping portion 350 is adapted to the first stopping portion 240; in this way, when the piercing device 300 is screwed in the holding casing 210, the position of the piercing device 300 is limited.

Preferably, in this case, a sealing ring 360 is further provided on the outer wall of the housing 310 for firmly sealing the piercing device 300 into the gas bottle holder 200 and enhancing the sealing effect between the gas bottle holder 200 and the piercing device 300. The sealing ring 360 can be used as an indicator for indicating the position of the housing 310 and helping with the operation of the user. For example, if the housing 310 is screwed into the holding casing 210 with the sealing ring 360 is completely received in the holing cavity 220, the user may stop screwing the housing 310; otherwise, the user should further screw the housing 310 into the holing cavity 220. Preferably, the sealing ring is in shape of an “◯”.

Referring to FIGS. 1-2 again, the stressing element 320 is received in the through-hole 313 of the housing 310, and is rotatable and movable with respect to the housing 310 further. The stressing element 320 is capable of synchronously rotating along with the housing 310 for being inserted into the gas bottle holder 200, or individually rotating and moving with respect to the housing 310 for pushing the piercing element 330 to pierce into the sealing membrane 110 or releasing gas inside the gas bottle 100.

Specifically, when the stressing element 320 rotates in a first direction P1 as is shown in FIG. 4, the stressing element 320 is retracted in a direction away from the gas bottle 100. However, when the stressing element 320 rotates in a second direction P2 as is shown in FIG. 6, the stressing element 320 is extended in a direction close to the gas bottle 100, and pushes the piercing element 330 to further pierce into the gas bottle 100.

In this case, the stressing element 320 is substantially in shape of a cylinder. An external thread (not shown) may be formed on an outer wall of the stressing element 320, while a corresponding internal thread (not shown) adapted to the external thread on the stressing element 320 may be formed on an inner wall of the housing 310. In this way, the stressing element 320 is rotatable with respected to the housing 310 and is further movable with respect to the housing 310 during the rotation thereof.

As is further shown in FIGS. 1-2, a second recess 321 is further defined at one end of the stressing element 320 that is away from the gas bottle 100 when the piercing device 300 is screwed into the gas bottle holder 200. The second recess 321 is capable of aligning with or misaligning with the first recess 314, in such a way that the stressing element 320 is synchronously rotated with the housing 310 or the stressing element 320 is individually rotated with respect to the housing 310. When the second recess is aligned with the first recess 314, the driving element is capable of being inserted into the first recess 314 and the second recess 321 simultaneously, thereby driving the housing 310 and the stressing element 320 to move or rotate synchronously. However, it is also possible to drive the stressing element 320 to rotate individually with respect to the housing 310 and further move in the housing 310 by using another driving element which is only inserted into the second recess 321. Preferably, a width b1 of the first recess 314 is larger than or equivalent to a width b2 of the second recess 321.

The piercing element 330 is fixed on the other end of the stressing element 20 that is close to the gas bottle 100. In this case, the piercing element 330 is in shape of a tip which is capable of being pierced into the sealing membrane 110 of the gas bottle 100, causing the high-pressure gas to escape from the gas bottle 100.

The operation of the magazine of the present application will be further described below accompanying with FIGS. 1-7.

As is shown in FIG. 3, initially, a gas bottle 100 is inserted into the gas bottle holder 200 reversedly (which means a mouth of the gas bottle 100 is located at a lower position than the bottom of the gas bottle 100 in a gravity direction), and the piercing device 300 is separated from the gas bottle cavity 200. When preparing the magazine for a pistol, the user firstly needs to align the piercing device 300 with the opening 230 of the gas bottle holder 200 to ensure a precise positioning of the piercing device 300.

After that, as is shown in FIG. 4, a first driving element (such as a metal plate) is inserted into the first recess 314 and the second recess 321 simultaneously, thereby driving the housing 310 and the stressing element 320 to screw synchronously and partially into the gas bottle holder 200. However, the piercing element 330 has not yet get into contact with the sealing membrane 110 of the gas bottle 100 at this time. And the first driving element is removed after that.

Then a second driving element is inserted into the second recess 321 only, and thus the stressing element 320 is controlled to rotate individually by the driving element (for example, one revolution) in the first direction P1. In this way, the stressing element 320 is moved backwardly for a certain distance in the direction away from the gas bottle 100. In this way, when the piercing element 330 is just pierced into the sealing membrane 110 of the gas bottle 100, the piercing element 330 will not be tightly clamped, thereby it is easily for the piercing element 330 to be screwed further after the sealing membrane 110 is pierced by the piercing element 330.

As is shown in FIG. 5, after the stressing element 320 is moved backwardly, the housing 310 together with the stressing element 320 are synchronously and completely screwed further in the second direction P2 by using the first driving element until the sealing ring 360 can not be seen from the outside. During this process, the piercing element 330 is pierced into the sealing membrane 110, and a sound indicating that the sealing membrane 110 is pierced may be heard.

After that, as is shown in FIG. 6, the stressing element 320 is controlled to rotate in the second direction P2 individually with respect to the housing 310 by the second driving element in such a way that, the stressing element 320 pushes the piercing element 330 to fully pierce into the gas bottle 100 in order to ensure that the gas exits evenly.

Finally, as is shown in FIG. 7, the stressing element 320 is controlled to rotate (for example, 0.5-1 revolution) in the first direction P1 individually with respect to the housing 310 by the second driving element in such a way that, the stressing element 320 is retracted backwardly in the direction away from the gas bottle 100. Preferably, in this case, the stressing element 320 is rotated until the stressing element 320 and the second end 312 of the housing 310 are at the same level.

In this way, the stressing element 320 will not block the gas outlet of the sealing membrane 110 formed by the piercing element 330. Since the piercing device 300 is screwed firmly inside the gas bottle holder 200, the piercing device 300 can be used as a sealing device for the gas bottle holder 200. Therefore, the gas can enter the holding cavity 210 of the gas bottle holder 200 before the whole magazine is applied into the pistol.

After that, the magazine can be portable and can be further inserted into a pistol to supply gas to the pistol.

Therefore, in the magazine and pistol of the present application, a piercing device 300 is provided for sealing the gas bottle holder and previously piercing the gas bottle. Therefore, there is sufficient time and space for the gas to gasify and the pressure of the gas is stable. In this way, when using the magazine of this type into the pistol, the gas can be evenly supplied to the pistol, the gas can be even used up, and an improved shooting effect can be achieved.
