Description

Technical Field

[0001] The utility model relates to an air gun, and more specifically, to an air gun adjusting mechanism capable of adjusting the air intake volume. Background Art

[0002] An air gun is a general term for firearms that use pressurized gas as power to launch projectiles. It is a light weapon that does not use gunpowder. It is a pistol that shoots the bullet by the pressure of compressed air or gas. The prototype of the air gun is the ancient drum air pipe.

[0003] Currently, for the air intake volume of the air gun, the existing air gun adjusting mechanism cannot adjust the air intake volume of the air gun, resulting in the air gun working under extremely high pressure for a long time, which may cause the gun body to rupture or other failures, and even cause harm to the user in severe cases.

[0004] For the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0005] In view of the problems in the related art, the utility model provides an air gun adjusting mechanism capable of adjusting the air intake volume to overcome the above technical problems existing in the existing related art.

[0006] To this end, the specific technical solution adopted by the utility model is as follows:

[0007] An air gun adjusting mechanism capable of adjusting the air intake volume includes an air gun body and a gas supply pipeline. The air gun body is connected to the gas supply pipeline. An adjusting pipeline is fixedly installed between the gas supply pipeline and the air gun body. A driving component is arranged on the outer surface of the adjusting pipeline. A cavity is opened inside the adjusting pipeline. An adjusting component is arranged inside the cavity. The adjusting component includes an inner pipe fixedly arranged inside the cavity. The outer surface of the inner pipe is fixedly installed inside the cavity through a fixing piece. An inner groove is opened on the inner pipe. A hollow circular plate is slidably connected inside the inner groove. A cross-shaped horizontal plate is fixedly connected inside the hollow circular plate. A U-shaped block is fixedly connected to the cross-shaped horizontal plate. One end of the inner groove far away from the hollow circular plate is rotatably connected with a rotating shaft rod. A rotating block is fixedly connected to the rotating shaft rod. A first connecting rod is hinged to the rotating block. The first connecting rod is hinged to the U-shaped block. A connecting ring is fixedly connected to the hollow circular plate. Through holes are equidistantly opened on the connecting ring.

[0008] Further, to facilitate the rotation of the rotating shaft rod, the driving component includes a driving box fixedly connected to the outer surface of the adjusting pipeline. A driving cavity is opened inside the driving box. An adjusting screw rod is rotatably connected inside the driving cavity. A moving block is threadedly connected to the adjusting screw rod. A second connecting rod is hinged to the moving block.

[0009] Further, in order to enable the rotating shaft rod to rotate as the moving block moves, one end of the rotating shaft rod sequentially passes through the inner tube, the fixing member, and the adjusting pipe, and extends into the driving cavity, and is fixedly connected to the rotating disk. One end of the second connecting rod away from the moving block is hinged to the rotating disk.

[0010] Further, in order to fix the adjusting pipe between the air gun body and the air supply pipe, an air inlet pipe is fixedly connected to one end of the adjusting pipe. The air inlet pipe communicates with the cavity and is connected to the air supply pipe. An air outlet pipe is fixedly connected to the other end of the adjusting pipe. The air outlet pipe communicates with the cavity and is connected to the air gun body.

[0011] Further, in order to increase the sealing performance between the hollow circular plate and the inner tube, a fixing ring is fixedly provided between the hollow circular plate and the connecting ring. The fixing ring is fixedly installed outside the hollow circular plate. A support ring is fixedly connected to one end of the cavity near the air outlet pipe. A first sealing ring is fixedly provided between the support ring and the fixing ring. The first sealing ring is fixedly connected to the fixing ring.

[0012] Further, in order to prevent gas from flowing out through the gap between the hollow circular plate and the inner tube, second sealing rings are equidistantly arranged between the hollow circular plate and the inner groove. The second sealing rings are equidistantly embedded on the inner wall of the inner groove.

[0013] Further, in order to facilitate the rotation of the adjusting screw rod, one end of the adjusting screw rod extends outside the driving box and is fixedly connected to a handwheel.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By rotating the handwheel, the adjusting screw rod rotates in the driving cavity, and the moving block slides on the adjusting screw rod. The sliding of the moving block causes the second connecting rod to move. The movement of the second connecting rod causes the rotating disk to rotate, and the rotating shaft rod rotates synchronously with the rotating disk. The rotation of the rotating shaft rod causes the rotating block to rotate accordingly, and the first connecting rod moves. The movement of the first connecting rod drives the hollow circular plate to slide in the inner groove. The sliding of the hollow circular plate causes the connecting ring to move accordingly. The movement of the connecting ring can adjust the size of the channel for gas flow between the inner tube and the cavity, thereby realizing the adjustment of the air intake volume, and can prevent the air gun from working under extremely high pressure for a long time, causing the gun body to rupture or other failures, and further preventing harm to the user.
