Description

Technical Field

[0001] The utility model relates to a high-pressure gas valve firing control device, in particular to a firing control device which utilizes pressure balance and the displacement of a shaft member to form an impact action. Background Art

[0002] Common existing firing devices are usually designed to fire special objects to be fired, and are suitable for different needs or uses. For example, a toy gun is mainly equipped with a small valve seat filled with gas, a gun body and a magazine that can be loaded with bullets such as BB bullets or paint bullets, and the bullets are fired by the gas filled to the bullets. However, the structure of the toy gun is quite complicated and difficult to assemble, so it is not suitable for a firing device that can be easily operated.

[0003] Taking the pneumatic rope-throwing gun used for rescue as an example, the filled high-pressure air is released to generate an instantaneous expansion explosive force, and the rope body is projected to the target area. It uses a high-pressure air bottle or a 30gm CO2 bottle as the pressure source. Taking the self-defense spray pepper spray as an example, a certain air pressure is usually given in advance to make a pressure container tank, and when in use, the release spray action is generated through the opening of the pressing head set at the top of the tank. However, both the rope-throwing gun and the spray pepper spray have the disadvantage of complex structure, and they are all independent single products. Their firing devices cannot be shared with each other or applied to other products. In addition, in terms of the existing spray pepper spray, since the air pressure in the pressure container tank is relatively low, it often happens that the pepper spray is blown back to the user by the wind due to the low pressure after being sprayed, resulting in the user's own injury.

[0004] In view of this, the applicant has designed a high-pressure gas valve firing control device after continuous research and experiments, which makes the structure and operation of the firing control device simpler and more convenient, and can be used with a variety of firing objects to meet different firing needs.

[0041] Please also see Figure 1 and Figure 2 , and cooperate with Figure 3, which are the stereogram, the stereogram exploded diagram and the cross-sectional view of the utility model. As shown in the figure, the utility model is provided with a firing seat 1 which can be filled with high-pressure gas, a connecting section 11 is provided at the front end of the firing seat 1, a through hole 111 is provided in the connecting section 11, and a leak-proof gasket 112 is embedded between the firing seat 1 and the connecting section 11. A first groove portion 12 is provided at the front edge of the firing seat 1, a second groove portion 13 is provided on the inner wall of the rear edge, and a symmetrical supporting portion 2 is provided in the second groove portion 13, wherein the supporting portion 2 is a block 21, 22 symmetrically arranged at an appropriate interval, and gas-stopping elements 211, 22 are provided on the blocks 21, 22, respectively. In this embodiment, the gas-stopping elements 211, 221 are oil seals or O-rings or gaskets.

[0042] The first groove 12 of the firing seat 1 is provided with a movable and hollow shaft 3, the front end of the shaft 3 is sleeved with a first piston 31 that can be supported in or detached from the through hole 111, a leak-proof gasket 311 is provided between the first piston 31 and the shaft 3, and a first elastic element 32 is passed through the shaft 3, and a sleeve portion 33 is provided at the end of the shaft 3, so that the sleeve portion 33 is sleeved in the second groove 13, and the blocks 21 and 22 of the supporting portion 2 are embedded in the inner edge of the sleeve portion 33. In this embodiment, the first elastic element 32 is conical, and its front and rear ends are respectively positioned at the rear edge of the first piston 31 and the front edge of the second groove 13.

[0043] A second piston 4 is provided between the sleeve portion 33 and the supporting portion 2, and a groove 41 is provided at the front end of the second piston 4 for a second elastic element 42 to be placed in the groove 41, so that the front and rear ends of the second elastic element 42 are respectively supported by the sleeve portion 33 at the end of the shaft 3 and the groove 41 of the second piston 4, thereby allowing the second piston 4 to be displaced between the sleeve portion 33 and the supporting portion 2. The center of the second piston 4 is set as a small diameter section 43.

[0044] The combination of the aforementioned components forms a high-pressure gas valve firing control device. When the second piston 4 is in the first position, the two ends of the second piston 4 abut against the supporting portion 2, and when the second piston 4 moves from the first position to the second position due to external pressure, the two ends of the second piston 4 leave the supporting portion 2, so that the small diameter section 43 in the center of the second piston 4 is located between the air stop elements 211 and 221, and a certain gap is formed between the air stop elements 211 and 221, so that the pressure of the first groove 12 and the second groove 13 in front and behind the firing seat 1 loses balance, and then the first piston 31 is separated from the through hole 111, so that the high-pressure gas can be discharged outward through the through hole 111. In this way, the utility model can be used to combine the connecting section 11 with the container that accommodates the object to be fired, and through the impact action of the aforementioned high-pressure gas, the object to be fired is pushed outward with a high thrust to fire.

[0045] See also Figure 4, which is a standby state diagram of the utility model. As shown in the figure, when the utility model is in the standby state, the shaft member 3 is in a stretched state due to the elasticity of the first elastic element 32, so that the first piston 31 is held against the through hole 111 of the firing seat 1, and the second piston 4 between the sleeve portion 33 and the holding portion 2 is in a stretched state due to the elasticity of the second elastic element 42, so that the two ends of the second piston 4 are against the air stop elements 211 and 221 of the blocks 21 and 22, so that the high-pressure gas inside the firing seat 1 and the first groove portion 12 and the second groove portion 13 achieve pressure balance, thereby forming a standby state.

[0046] See also Figure 5 , which is an action state diagram of the utility model. As shown in the figure, when the utility model is used, a push button or other brake member is used to apply force to the end of the second piston 4 from the outside, so that the second piston 4 moves from the first position to the second position, so that the two ends of the second piston 4 are relatively separated from the air stop elements 211 and 221 of the supporting portion 2, so that the small diameter section 43 in the center of the second piston 4 is located between the air stop elements 211 and 221, and a certain gap is formed between the air stop elements 211 and 221, so that the high-pressure gas stored in the second groove 13 flows from the gap to the hollow part of the shaft 3, thereby causing the pressure of the first groove 12 and the second groove 13 to lose balance.

[0047] See also Figure 6 , which is the second action state diagram of the utility model. As shown in the figure, when the pressure of the first groove 12 and the second groove 13 lose balance, since the pressure of the first groove 12 is greater than that of the second groove 13, the shaft 3 will be pushed backward due to the pressure imbalance, so that the first piston 31 at the front end is separated from the through hole 111 of the through hole connecting section 11, so that the high-pressure gas can be discharged outward through the through hole 111. In this way, the utility model can be combined with the connecting section 11 to accommodate objects to be fired (such as: paste pepper water or BB bullets, paint bullets and other bullet-shaped objects, spheres, or other objects such as rescue nets) waiting for firing, and the impact action of the aforementioned high-pressure gas can push the objects to be fired outward with high thrust.

[0048] See also Figure 7 , which is a diagram of the return action state of the utility model. As shown in the figure, after the high-pressure gas is released outward through the through hole 111, the shaft 3 will re-hold the first piston 31 against the through hole 111 due to the elasticity of the first elastic element 32, and the second piston 4 will re-rest against the gas-stopping elements 211, 221 of the supporting part 2 blocks 21, 22 due to the elasticity of the second elastic element 42, so as to return to the standby state for filling the high-pressure gas.

[0049] The above embodiments are only for illustrating the preferred implementation of the present invention, but not for limiting the scope of the present invention. Any slight modification or change will not lose the essence of the present invention and will not deviate from the spirit of the present invention.

[0050] In summary, the utility model comprises a firing seat, a shaft member contained in the firing seat, and a piston that can be displaced by pressing, to form a high-pressure gas valve firing control device. By utilizing pressure balance and the displacement of the shaft member, an impact action is formed to match a variety of firing objects to be fired, thereby achieving a firing control device corresponding to different firing requirements.
