Description

Technical Field

[0001] This utility model relates to the field of air gun technology, and in particular to a gas-storage air gun. Background Technology

[0002] Gas-filled air guns store compressed gas through built-in or external high-pressure gas tanks, and release the gas to propel the projectile when fired. Their working principle is similar to a pre-filled "air pump system", and the gas pressure can reach 20-30 MPa, which is much higher than that of ordinary manually refilled air guns.

[0003] A search revealed, for example, that invention CN107976111A discloses a pre-charged air gun with self-inflating function, comprising a gun body and an inflation cylinder. The gun body is provided with an inflation cylinder for pre-storing gas, which includes an inlet end and an outlet end. The outlet end is connected to the firing assembly of the air gun. When the pre-charged air gun is in use, when the high-pressure gas instantly propels the projectile, some of the gas will backflow against the gun body, which can easily cause impact to the operator's body. When the butt part comes into contact with the operator's body, the recoil can easily cause injury to the operator's body. However, this utility model does not make it easy to reduce the recoil force acting on the operator's body. Therefore, in order to solve the above defects, the inventor proposes a pre-charged air gun. Utility Model Content

[0004] The main purpose of this invention is to provide a gas-storage air gun, which can effectively solve the problem that existing air guns are not easy to reduce the recoil force acting on the operator's body.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A gas-storage air gun includes a gun body, a bullet, and a stock fixedly mounted on one side of the gun body. A shock-absorbing box is fixedly mounted on one side of the outer surface of the stock. A shock-absorbing airbag is fixedly mounted inside the shock-absorbing box. A rubber pad is slidably connected inside the shock-absorbing box and is fixedly connected to the outer surface of the shock-absorbing airbag.

[0007] An air supply cylinder is fixedly installed on one side of the outer surface of the shock absorber box. An air inlet pipe with a one-way valve is fixedly installed on one side of the outer surface of the air supply cylinder. The end of the air inlet pipe away from the air supply cylinder passes through the shock absorber box and is fixedly connected to the shock absorber airbag. An air suction pipe with a one-way valve is fixedly installed on one side of the outer surface of the air supply cylinder.

[0008] Preferably, a piston rod is slidably connected to one side of the air supply cylinder. One end of the piston rod is located inside the air supply cylinder and a piston is fixedly installed thereon. The other end of the piston rod extends to the outside of the air supply cylinder and a pressing plate is fixedly installed thereon. A second spring is fixedly connected between the pressing plate and the outer surface of the air supply cylinder, and the second spring is sleeved on the outer end of the piston rod.

[0009] Preferably, an operating hole is provided on one side of the outer surface of the shock-absorbing box, and an air nozzle is provided on the outer surface of the shock-absorbing airbag on the side of the operating hole.

[0010] Preferably, a gas storage tube is fixedly installed inside the stock, and a first gas cylinder and a second gas cylinder are provided inside the gas storage tube. A front plug is fixedly installed at the front end of the gas storage tube, and a rear plug is fixedly installed at the rear end of the gas storage tube. A needle is provided on the opposite side of the front plug and the rear plug, and a gas tube is provided on the inside side of the front plug.

[0011] Preferably, the gun body is provided with a top spring plug inside, and a first spring is fixedly installed on one side of the gun body, and the first spring is fixedly connected to the top spring plug.

[0012] Preferably, a trigger is movably connected to one side of the gun body, and one side of the trigger extends to the outside of the gun body. A bolt is provided on one side of the gun body, and a hammer is rotatably connected to one side of the gun body. A lever is provided on one side of the outer surface of the gun body. A receiver base plate is provided on one side of the gun body, and a rocker arm is provided on one side of the gun body. A barrel sleeve is provided on the side of the gun body near the bolt.

[0013] Preferably, the gun body has a firing pin on one side inside, and the buttstock has a gas release valve on the side near the hammer, with a valve pin on the side of the gas release valve.

[0014] Preferably, a cartridge tube cover is provided on one side of the outer surface of the gun body, and a projectile is provided inside the bullet.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a gas-storage air gun. By setting a shock-absorbing box, in actual operation, the operator applies a pushing force to the pressing plate, causing the piston rod to push the piston towards the inside of the air cylinder. When the piston moves, it will transmit the air in the air cylinder to the shock-absorbing airbag through the air intake pipe, causing the shock-absorbing airbag to expand and push the rubber pad to the outside of the shock-absorbing box and into contact with the operator's body. The recoil generated by firing the projectile will cause the buttstock to push the shock-absorbing box towards the operator, which will then compress the shock-absorbing airbag and the rubber pad. Thus, the recoil force acting on the operator's body can be effectively reduced through the shock-absorbing airbag and the rubber pad, effectively reducing the damage caused by the recoil force to the operator's body.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] This utility model discloses a gas-storage type air gun, such as Figure 1-12As shown, the gun includes a gun body 1, a bullet 12, and a stock 2 fixedly mounted on one side of the gun body. A shock absorber box 3 is fixedly mounted on one side of the outer surface of the stock 2. A shock absorber airbag 301 is fixedly mounted inside the shock absorber box 3. A rubber pad 302 is slidably connected inside the shock absorber box 3, and the rubber pad 302 is fixedly connected to the outer surface of the shock absorber airbag 301. When the shock absorber airbag 301 is inflated, it will push the rubber pad 302 to move outward from the shock absorber box 3 until a part of the rubber pad 302 extends to the outside of the shock absorber box 3.

[0031] An air cylinder 303 is fixedly installed on one side of the outer surface of the shock absorber box 3. An air inlet pipe 304 with a one-way valve is fixedly installed on one side of the outer surface of the air cylinder 303. The one-way valve of the air inlet pipe 304 allows air in the air cylinder 303 to enter the shock absorber airbag 301 through the air inlet pipe 304, but air in the shock absorber airbag 301 cannot enter the air cylinder 303 through the air inlet pipe 304.

[0032] Furthermore, the end of the air inlet pipe 304 away from the air delivery cylinder 303 passes through the shock absorber box 3 and is fixedly connected to the shock absorber airbag 301. A suction pipe 305 with a one-way valve is fixedly installed on one side of the outer surface of the air delivery cylinder 303. The one-way valve of the suction pipe 305 allows external air to enter the air delivery cylinder 303 through the suction pipe 305, but the air inside the air delivery cylinder 303 cannot be transmitted to the external environment through the suction pipe 305.

[0033] A piston rod 307 is slidably connected to one side of the air cylinder 303. One end of the piston rod 307 is located inside the air cylinder 303 and a piston 306 is fixedly installed thereon. The other end of the piston rod 307 extends to the outside of the air cylinder 303 and a pressing plate 309 is fixedly installed thereon. A second spring 308 is fixedly connected between the pressing plate 309 and the outer surface of the air cylinder 303. The second spring 308 is sleeved on the outer end of the piston rod 307. When the operator pushes the pressing plate 309 toward the side of the second spring 308, the pressing plate will squeeze the second spring 308. At the same time, the piston rod 307 will drive the piston 306 to move toward the inside of the air cylinder 303, so that the air in the air cylinder 303 is transmitted to the shock-absorbing airbag 301 through the air inlet pipe 304, causing the shock-absorbing airbag 301 to inflate.

[0034] When the operator stops pushing the pressing plate 309, the compressed spring will push the pressing plate 309 to reset, which will cause the piston rod 307 to drive the piston 306 to move outward of the air cylinder 303, so that external air will enter the air cylinder 303 through the air intake pipe 305, so that air can be injected into the shock-absorbing airbag 301 again.

[0035] An operation hole 3021 is provided on one side of the outer surface of the shock absorber box 3, and an air nozzle 3022 is provided on the outer surface of the shock absorber airbag 301 on the side of the operation hole 3021. The operator can use the air nozzle 3022 through the operation hole 3021 to expel the air from the shock absorber airbag 301.

[0036] The stock 2 has a gas storage tube 6 fixedly installed inside, and the gas storage tube 6 has a first gas cylinder 4 and a second gas cylinder 5 inside. The front end of the gas storage tube 6 is fixedly installed with a front plug 9, and the rear end of the gas storage tube 6 is fixedly installed with a rear plug 7. The front plug 9 and the rear plug 7 are each provided with a needle 8 on the opposite side. The front plug 9 has a gas tube 10 on one side inside.

[0037] The air gun uses disposable compressed carbon dioxide cylinders as its gas source, and two cylinders are used for each installation.

[0038] During installation, the neck of the first gas cylinder is inserted first, followed by the bottom of the second gas cylinder. After the two gas cylinders are inserted, the gas storage tube 6 will have a front plug 9 and a rear plug 7. Both the front plug 9 and the rear plug 7 are equipped with piercing needles 8. Tightening the front plug 9 and the rear plug 7 of the gas storage tube 6 will puncture the necks of the two carbon dioxide gas cylinders, filling the gas storage tube 6 with carbon dioxide, which is then transported to the vent valve 24 through the gas pipe 10.

[0039] Inside the gun body 1 is a top plug 13. A first spring 14 is fixedly installed on one side of the gun body 1 and is fixedly connected to the top plug 13. Under the action of the first spring 14, the top plug 13 pushes the bullet 12 to the right, and the bullet 12 is pressed against the lower part of the bolt 16 by the force.

[0040] A trigger 15 is movably connected to one side of the gun body 1, and one side of the trigger 15 extends to the outside of the gun body 1. A bolt 16 is provided on one side of the gun body 1, and a hammer 17 is rotatably connected to one side of the gun body 1. A lever 19 is provided on one side of the outer surface of the gun body 1. A receiver base plate 18 is provided on one side of the gun body 1, and a rocker arm 21 is provided on one side of the gun body 1. A barrel sleeve 23 is provided on the side of the gun body 1 closest to the bolt 16.

[0041] When lever 19 is pressed down, bolt 16 is blocked from moving to the right by the locking block, causing receiver base plate 18 to move down. The movement of receiver base plate 18 moves the locking block down, and after the locking block moves down, bolt 16 moves to the right. Bullet 12 moves to the right along with bolt 16 along the follower until it hits the gas valve 24. Bolt 16 moves to the right, pushing hammer 17 down. Lever 19 continues to rock down and moves bolt 16 to the right. Bolt 16 moves to the right, pushing follower rocker arm 21 to rotate around the fixing pin. The rotating follower feeds bullet 12 upward. The remaining bullets 12 are blocked by receiver base plate 18. After bullet 12 reaches between barrel sleeve 23 and pusher, it is jammed by both.

[0042] As the bolt 16 moves to the right, it pushes the hammer 17 to the position locked by the sear. After the lever 19 is lowered to its position, it is raised in the opposite direction. The upward movement of the lever 19 causes the bolt 16 to move to the left. After the bolt 16 moves to the left, the follower arm 21 moves the follower downward. When the bolt 16 and the follower are both in position, the bullet 12 moves to the right and presses against the bolt 16. The upward movement of the lever 19 causes the magazine base plate to move upward. The upward movement of the magazine base plate pushes the locking block upward until both are in position. After they are in position, the bolt 16 is locked by the locking block. Through the above actions, the bullet 12 is chambered, and the air gun is ready to fire.

[0043] The gun body 1 has a firing pin 25 on one side inside, and the stock 2 has a gas release valve 24 on the side near the hammer 17 inside, and a valve pin 26 on the side of the gas release valve.

[0044] A tube cover 27 is provided on one side of the outer surface of the gun body 1. The bullet 12 contains a projectile 28. The projectile 28 is loaded into the bullet 12, and then the bullet 12 containing the projectile 28 is loaded into the tube through the tube cover 27. This process is repeated to complete the loading of multiple bullets 12.

[0045] The working principle of this utility model is as follows: During installation, the mouth of the first gas cylinder is inserted first, followed by the bottom of the second gas cylinder. After the two gas cylinders are inserted, the front plug 9 and the rear plug 7 of the gas storage tube 6 are tightened. The piercing needle 8 will then puncture the mouths of the two carbon dioxide gas cylinders, filling the gas storage tube 6 with carbon dioxide, which is then transported to the venting valve 24 through the gas pipe 10.

[0046] The bullet 28 is loaded into the bullet 12, and then the bullet 12 containing the bullet 28 is loaded into the bullet tube through the tube cover 27. This process is repeated to complete the loading of multiple bullets 12. Under the action of the first spring 14, the top plug 13 pushes the bullet 12 to the right, and the bullet 12 is pressed against the lower part of the bolt 16 by the force.

[0047] As lever 19 is depressed, bolt 16 is blocked from moving to the right by the locking block, causing receiver base plate 18 to move downwards. This downward movement of receiver base plate 18, in turn, causes the locking block to move downwards. After the locking block moves downwards, bolt 16 moves to the right, and bullet 12 moves to the right along with the follower and bolt 16 until it hits the gas valve 24. Bolt 16's rightward movement pushes hammer 17 downwards, and lever 19 continues to rock downwards, further pushing bolt 16 to the right. Bolt 16's rightward movement pushes follower rocker arm 21 to rotate around the fixing pin. The rotating follower pushes bullet 12 upwards, while the remaining bullets 12 are blocked by receiver base plate 18. Bullet 12 then reaches the barrel sleeve 23 and the feed mechanism. After a short time, the bolt 16 is locked by both of them. As the bolt 16 moves to the right, it pushes the hammer 17 to the position locked by the sear. After the lever 19 is lowered to its position, it is raised in the opposite direction. The upward movement of the lever 19 causes the bolt 16 to move to the left. After the bolt 16 moves to the left, the follower arm 21 moves the follower to its position. When the bolt 16 and the follower are both in position, the bullet 12 moves to the right and presses against the bolt 16. The upward movement of the lever 19 causes the magazine base plate to move upward. The upward movement of the magazine base plate pushes the locking block upward until both are in position. After they are in position, the bolt 16 is locked by the locking block. Through the above actions, the bullet 12 is chambered, and the air gun is ready to fire.

[0048] Push the safety to the right to close it, press the lever 19 upward to push the trigger 15 stop plate away. After the trigger 15 stop plate is pushed away from the position blocking the trigger 15, the trigger 15 can be pulled. The pulled trigger 15 rotates around the axis to the position of the sear, causing the sear to rotate together. The end of the sear that is holding the hammer 17 also rotates and eventually disengages from the hammer 17. The hammer 17 is released and strikes the firing pin 25. After being stressed, the firing pin 25 strikes the valve pin 26, opening a gap between the valve pin 26 and the vent valve 24, compressing carbon dioxide gas and releasing it. The projectile 28 is then propelled out. The above is the firing process of bullet 12.

[0049] The recoil generated by firing the projectile 28 will cause the stock 2 to push the shock absorber 3 toward the operator, which will then compress the shock absorber airbag 301 and the rubber pad 302. Thus, the shock absorber airbag 301 and the rubber pad 302 can effectively reduce the recoil acting on the operator's body.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
