Description

Technical Field

[0001] This utility model relates to a threaded striking and piercing air pistol, 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 the advantages of long range, low noise, low recoil, simple use, convenient maintenance, and high safety. They have gradually become a popular sport shooting and recreational product. To facilitate the installation of the gas cylinder, a gas cylinder-type air pistol, as disclosed in application number CN201410243503.1, has emerged. In this air pistol, the gas cylinder is inserted into the air tube, and the gas cylinder is pushed into the air tube by screwing in the locking sleeve to achieve connection with the air intake structure. This installation method directly connects the gas cylinder to the air intake structure, which can puncture the gas cylinder and easily lead to accidental firing of the bullet by pulling the trigger before shooting. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a threaded strike-and-pierce type air pistol, in which the air cylinder is pre-loaded and then struck and pierced when it is ready to fire, which is convenient to operate and has better safety, and can overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a threaded striking and piercing air pistol, comprising a gun body with an air cylinder mounting cavity, an air intake structure connected to the top of the air cylinder at one end of the air cylinder mounting cavity, and a pushing mechanism at the other end for pushing the air cylinder toward the air intake structure. The air intake structure includes an air intake valve seat and a piercing needle disposed within the valve seat. The pushing mechanism includes a hollow base spirally connected to the gun body, and a push rod slidably connected to the base. The push rod engages with the base in a blocking manner. When the base rotates and moves, it can drive the push rod to move together toward the air intake structure. The base engages with the gun body in a blocking manner. When the air cylinder is pushed to the first position by the rotation of the push rod assembly, the base and the gun body block it from continuing to push it toward the air intake structure. The push rod moves the air cylinder to the second position. In the first position, the piercing needle does not pierce it; in the second position, the piercing needle pierces it.

[0005] Furthermore, the push rod has a receiving end that passes through the base, the receiving end abutting against the end that passes through the base, and the receiving end has a concave contact surface that mates with the bottom of the gas cylinder.

[0006] Furthermore, the push rod assembly has an elastic reset mechanism, which includes an elastic element that generates elastic force through elastic deformation. During the process of the push rod pushing the gas cylinder upward to the second position, the elastic element deforms to generate elastic force. When the external force is removed, the elastic force pushes the push rod back to the position before it was pushed.

[0007] By implementing this utility model, when installing the gas cylinder, the gas cylinder is placed in the gas cylinder installation cavity. The pushing mechanism first rotates and tightens to push the gas cylinder towards the air intake structure to the first position. At the first position, the needle does not pierce it. When preparing to fire, the push rod pushes the gas cylinder to continue moving towards the air intake structure to the second position, so that the needle pierces it. This makes operation more convenient and has better safety. Attached Figure Description

[0012] Embodiments of this utility model: such as Figures 1 to 3 As shown, a threaded strike-and-pierce air pistol includes a gun body 1 with an air cylinder mounting cavity. One end of the air cylinder mounting cavity has an air intake structure that mates with the top of an air cylinder 2, and the other end has a pushing mechanism for conveniently pushing the air cylinder 2 towards the air intake structure. The air intake structure includes an air intake valve seat 3 and a piercing needle 4 disposed within the air intake valve seat 3. The air intake valve seat 3 has a sealing ring 5 that mates with and seals against the outer wall of the air cylinder 2. The sealing ring 5 is located in front of the piercing needle 4 at a certain distance. The pushing mechanism includes a hollow base 6 spirally connected to the gun body 1, and a push rod 7 slidably connected to the base 6. When the base 6 is tightened, it moves the push rod 7 upwards, pushing the gas cylinder 2 towards the air intake structure until the base 6 blocks the gun body. At this point, the gas cylinder 2 is in the first position. In this position, the top of the gas cylinder 2 is located inside the air intake valve seat 3 and is sealed with the sealing ring 5, while the piercing needle 4 does not pierce it. When firing, striking the push rod 7 moves it upwards relative to the base 6, moving the gas cylinder 2 to the second position. At this point, the piercing needle 4 pierces the gas cylinder 2, and the high-pressure gas passes through the air intake valve seat 3 and fires the bullet. This achieves the two-step process of pre-loading and piercing the gas cylinder 2, making it safer.

[0013] As a preferred embodiment, the push rod 7 has a receiving end 8 that passes through the base 6. The receiving end 8 abuts against the end that passes through the base 6. The receiving end 8 has a concave contact surface that mates with the bottom of the gas cylinder 2. When the base 6 moves upward, it abuts against the receiving end 8, causing the push rod 7 to move upward together and push the gas cylinder 2 to the first position. This makes the receiving end 8 have a concave contact surface that mates with the bottom of the gas cylinder 2, thus limiting its movement when it comes into contact with the gas cylinder 2 and improving stability.

[0014] As a preferred embodiment, the push rod assembly has an elastic reset mechanism, including a reset spring 9 installed in the base 6 and acting on the push rod 7. The reset spring 9 is the elastic element. During the process of the push rod 7 pushing the gas cylinder 2 upward from the first position to the second position, the reset spring 9 is compressed. When the external force is removed, the reset spring 9 resets and pushes the push rod 7 downward and holds it at the position where the receiving end 8 abuts against the top of the base 6, keeping the push rod 7 stable and preventing it from shaking during use. In addition, to make the push rod assembly more stable when moving, the push rod 7 and the base 6 have a keyway structure that matches. That is, the push rod 7 and the base 6 are keyway matched. When the base 6 rotates, it drives the push rod 7 to rotate together and move as a whole.
