Description

Technical Field

[0001] This utility model relates to a puncture mechanism for a gas cylinder-type air gun, belonging to the field of air gun technology. Background Technology

[0002] Carbon dioxide kinetic energy air guns use compressed carbon dioxide gas as power and have advantages such as long range, low noise, low recoil, simple operation, convenient maintenance, and high safety. They are gradually becoming a popular sport shooting and recreational product. The gun body has a cavity for holding the gas cylinder and an exhaust channel connected to the cavity. The exhaust channel has a valve assembly controlled by a trigger assembly. The cavity has an opening for inserting the gas cylinder, and a sealing cap assembly is installed at the opening. The locking cap assembly is screwed to the opening and has a piercing needle. After the gas cylinder is inserted into the cavity, the locking cap assembly is tightened at the opening, and the piercing needle pierces the gas cylinder. Gas is released and enters the exhaust channel. The trigger assembly controls the valve assembly to open and close, controlling the gas discharge and firing the bullet. This method of piercing the gas cylinder may cause it to puncture before the locking cap assembly is tightened and sealed at the opening, resulting in gas leakage. This installation method, which involves puncturing the gas cylinder before firing, also easily leads to the dangerous situation of prematurely firing the bullet. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a puncture mechanism for a gas cylinder-type air gun, which can prevent gas leakage during installation and prevent the gas cylinder from being punctured in advance, thus overcoming the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a piercing mechanism for a gas cylinder-type air gun, including a cavity connected to the exhaust channel for placing a gas cylinder, one end of the cavity being an open end, and a detachable locking cap assembly with a piercing needle being installed, including a sliding body and a driving device, the end of the cavity away from the locking cap assembly having an inner hole for the sliding body to pass through, the sliding body being slidably connected in the inner hole and sliding through the driving device to push the gas cylinder in the cavity from the position where it has never been in contact with the piercing needle to the position where the piercing needle pierces it.

[0005] Furthermore, the driving device is a trigger assembly.

[0006] Furthermore, an elastic body is installed in the inner hole, the elastic body having a spring force that pushes the sliding body to slide towards the gas cylinder.

[0007] By implementing this utility model, during installation, the gas cylinder is placed into the cavity from the opening end, and the locking cap assembly is sealed at the opening. At this time, the piercing needle does not contact the gas cylinder, and the gas cylinder is in a sealed state. When firing is required, the driving device drives the sliding body to slide and push the gas cylinder towards the locking cap assembly so that the piercing needle can pierce it. This can prevent gas leakage during installation and prevent dangerous situations caused by premature piercing of the gas cylinder. Attached Figure Description

[0012] Embodiments of this utility model: such as Figures 1 to 3 As shown, a piercing mechanism for a gas cylinder-type air gun includes a cavity 3 connected to an exhaust channel for holding a gas cylinder 2. The left end of the cavity 3 is open, and a locking cap assembly 5 is screwed onto it. The locking cap assembly 5 has a sealing ring and a piercing needle 4, which seals the open end when tightened. This application includes a sliding body 6 and a driving device. The right side of the cavity 3 has an inner hole 7 for the sliding body 6 to pass through, and a sealing ring that seals with the sliding body 6 is provided in the inner hole 7. In use, the gas cylinder 2 is first placed into the cavity 3 from the open end of the cavity, and the locking cap assembly 5 is tightened. The seal is installed at the opening. At this time, the needle 4 is not in contact with the gas cylinder 2, and the gas cylinder 2 is in a sealed state. When firing is required, the drive device drives the sliding body 6 to slide to the left, pushing the gas cylinder 2 towards the locking cap assembly 5 so that the needle 4 punctures it. After the gas is released, it enters the cavity 3 and enters the exhaust channel through the air pipe 1. The air pipe 1 can be directly connected to the cavity 3 or connected to the inner hole 7. The gas enters the inner hole 7 through the cavity 3 and then enters the exhaust channel through the air pipe 1. When firing, the trigger assembly controls the valve assembly to open and close the exhaust channel to achieve the firing of the bullet.

[0013] As a preferred option, the driving device is a trigger assembly, which includes a trigger 8 hinged to the gun body. When the trigger 8 is pulled for the first time, the trigger 8 pushes the sliding body 6 to the left, pushing the gas cylinder 2 towards the locking cap assembly 5 so that the piercing needle 4 pierces it. When the trigger 8 is pulled again, the bullet is fired. The piercing operation of the gas cylinder 2 is achieved by using the existing trigger assembly, which makes the operation more convenient.

[0014] As a preferred embodiment, a spring 9 is installed in the inner hole 7. The spring 9 is an elastic body. The spring is compressed in the inner hole 7 and contacts the sliding body 6. It has the elastic force to push the sliding body 6 to slide towards the gas cylinder 2. When the gas cylinder 2 is placed in the cavity 3, the elastic force of the spring 9 alone cannot push the gas cylinder 2 to the left. When the trigger 8 is pulled to push the sliding body 6 to the left and drive the gas cylinder 2 to the left, the elastic force of the spring 9 plays an assisting role. Pulling the trigger 8 can push the gas cylinder 2 to the left with less effort to achieve the puncture operation. Moreover, the force of the spring 9 can keep the sliding body 6 in the position after being pushed, which plays a better role in limiting the gas cylinder 2.
