Technical Field

[0001] This utility model relates to the field of air gun technology, and in particular to an air gun with a lever-fired structure. Background Technology

[0002] An air gun is a cold-powered shooting device that uses the instantaneous release of compressed gas to propel a bullet, and it is widely used in the field of shooting. Existing air guns use a hammer-fired mechanism to fire bullets, which is complex and cumbersome to assemble. Summary of the Invention

[0003] The purpose of this invention is to provide an air gun with a lever-fired structure to solve the problem that existing air guns use a hammer-fired structure to fire bullets, which is complex in structure and cumbersome in assembly.

[0004] This utility model is achieved through the following technical solution:

[0005] An air gun with a lever-fired mechanism includes a gun body, a trigger, a chambering block, an airtight block, and a drive arm. The gun body has a compression chamber and an ejection chamber. The ejection chamber is connected to the compression chamber via a connecting port. The drive arm can rotate relative to the gun body to open or close the connecting port of the airtight block. The chambering block can move into or out of the ejection chamber. When the chambering block exits the ejection chamber, it drives the drive arm to rotate, causing the airtight block to close the connecting port. When the chambering block moves into the ejection chamber, the trigger can drive the drive arm to rotate, causing the airtight block to open the connecting port of the airtight block.

[0006] Furthermore, a compression block is provided inside the compression chamber, and a compression arm is rotatably connected to the gun body to drive the compression block to move along the compression chamber. When the compression block moves toward the communication port, it compresses the gas.

[0007] Furthermore, when the airtight block closes the communication port, the position of the drive arm is defined as the loaded position. The drive arm has a first limiting hook, and the trigger has a second limiting hook. When the drive arm rotates to the loaded position, the first limiting hook engages with the second limiting hook to restrict the rotation of the drive arm. When the airtight block opens the communication port, the position of the drive arm is defined as the firing position. The trigger can rotate relative to the gun body to disengage the second limiting hook from the first limiting hook. A first elastic element is provided between the drive arm and the trigger. When the second limiting hook disengages from the first limiting hook, the drive arm is driven by the first elastic element to rotate toward the firing position.

[0008] Furthermore, the airtight block is provided with a second elastic element, which can drive the airtight block to move away from the communication port.

[0009] Furthermore, the gun body has an outer tube, a cartridge tube, and a gas valve. The gas valve is located inside the outer tube and partially extends out of the outer tube and is connected to the cartridge tube. The gas valve and the outer tube cooperate to form the compression chamber, and the gas valve and the cartridge tube cooperate to form the ejection chamber. The gas valve has a connecting channel that connects the compression chamber and the ejection chamber. The connecting port is formed in the connecting channel. The airtight block is at least partially accommodated in the connecting channel and can move along the connecting channel to open and close the connecting port.

[0010] Furthermore, the airtight block is provided with a first sealing ring that abuts against the wall of the connecting channel cavity; and / or the connecting channel is inclined forward from bottom to top.

[0011] Furthermore, the connecting channel is connected to the ejection chamber via the air outlet, and the front end of the air valve extending out of the outer tube is connected to the cartridge tube, while the rear end is for the insertion of the loading block;

[0012] Furthermore, when the chamber block is inserted into the gas valve, it can push the bullet to the front of the gas outlet. A third sealing ring is provided at one end of the chamber block that is inserted into the gas valve. The third sealing ring abuts against the wall of the bullet ejection chamber and is located behind the gas outlet when the chamber block is inserted into the gas valve.

[0013] Furthermore, the air valve is detachably and fixedly connected to the outer tube and the spring tube, respectively.

[0014] Furthermore, the gun body also includes an inner tube disposed within the outer tube, the gas valve is disposed between the inner tube and the compression block, and the trigger, the chambering block and the drive arm are disposed on the inner tube.

[0015] Furthermore, the chambering block is slidably connected to the gun body, one of the chambering block and the gun body is provided with a guide groove, and the other of the chambers is provided with a guide strip that slidably engages with the guide groove; and / or the airtight block is detachably fixedly connected to the drive arm; and / or the compression block is provided with a second sealing ring that abuts against the inner wall of the compression chamber.

[0016] The advantages of this technical solution are that by configuring a trigger, a chambering block, and a drive arm on the gun body, and configuring a gas-tight block on the drive arm, when the chambering block moves out of the ejection chamber, the drive arm swings to close the communication port of the gas-tight block, sealing the compression chamber and pressurizing it. When the chambering block moves into the ejection chamber, the trigger flips back, causing the drive arm to swing and the gas-tight block to open the communication port, thus firing the bullet. The firing structure is simple, and the assembly is easy and quick. Compared with the hammer firing structure, it has a shorter air passage, higher firing air pressure, and better firing effect.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Figure 1-10 As shown, the air gun with a lever-fired structure includes a gun body 1, a trigger 2, a chambering block 3, an airtight block 4, and a drive arm 5. The gun body 1 has a compression chamber 101 and a discharge chamber 102. The compression chamber 101 is connected to the discharge chamber 102 via a connecting port 103. The drive arm 5 is rotatably connected to the gun body 1. The airtight block 4 is located at one end of the drive arm 5. The drive arm 5 can rotate relative to the gun body 1 to open or close the connecting port 103 of the airtight block 4. The chambering block 3 can move into or out of the discharge chamber 102. When the chambering block 3 exits the discharge chamber 102, it drives the drive arm 5 to rotate, causing the airtight block 4 to close the connecting port 103. When the chambering block 3 moves into the discharge chamber 102, the trigger 2 can drive the drive arm 5 to rotate, causing the airtight block 4 to open the connecting port 103.

[0031] When firing a bullet using this air gun with a lever-fired structure, the steps are as follows: First, the chambering block 3 moves backward and exits the ejection chamber 102, causing the drive arm 5 to rotate and close the communication port 103 with the airtight block 4. Next, the compression chamber 101 is pressurized. Then, the chambering block 3 moves forward and inserts into the ejection chamber 102. During the forward movement of the chambering block 3, the bullet is pushed into the ejection chamber 102. Then, the trigger 2 is pulled, and the trigger 2 flips backward, causing the drive arm 5 to rotate and open the communication port 103 with the airtight block 4. High-pressure gas enters the ejection chamber 102 from the compression chamber 101 and fires the bullet.

[0032] In summary, this embodiment provides an air gun with a lever-fired structure to solve the problems of complex structure and cumbersome assembly in existing air guns that use a hammer-fired structure to fire bullets. The main improvement is achieved by configuring a trigger 2, a chambering block 3, and a drive arm 5 on the gun body 1, with an airtight block 4 mounted on the drive arm 5. When the chambering block 3 moves out of the ejection chamber 102, it drives the drive arm 5 to swing, causing the airtight block 4 to close the communication port 103, sealing and pressurizing the compression chamber 101. When the chambering block 3 moves into the ejection chamber 102, the trigger 2 flips backward, causing the drive arm 5 to swing, causing the airtight block 4 to open the communication port 103 and fire the bullet. The firing structure is simple, and assembly is quick and easy. Compared to a hammer-fired structure, it has a shorter air passage, higher firing pressure, and better firing effect.

[0033] In this embodiment of the invention, a compression block 6 is provided inside the compression chamber 101, and a compression arm 7 is rotatably connected to the gun body 1 to drive the compression block 6 to move along the compression chamber 101. When the compression block 6 moves toward the connecting port 103, it compresses the gas. This configuration, by placing the compression block 6 inside the compression chamber 101 and the compression arm 7 on the gun body 1 to drive the compression block 6 to move along the compression chamber 101, allows the user to pressurize the compression chamber 101 by rotating the compression arm 7 to move the compression block 6 toward the connecting port 103 when the airtight block 4 closes the connecting port 103. The pressurization operation is simple and convenient to implement.

[0034] In this embodiment of the utility model, the position of the drive arm 5 when the airtight block 4 closes the communication port 103 is defined as the loaded position, and the position of the drive arm 5 when the airtight block 4 opens the communication port 103 is defined as the firing position. The drive arm 5 has a first limiting hook 501, and the trigger 2 has a second limiting hook 201. When the drive arm 5 rotates to the loaded position, the first limiting hook 501 engages with the second limiting hook 201 to restrict the rotation of the drive arm 5. The trigger 2 can rotate relative to the gun body 1 to disengage the second limiting hook 201 from the first limiting hook 501. A first elastic element 8 is provided between the drive arm 5 and the trigger 2. When the second limiting hook 201 disengages from the first limiting hook 501, the drive arm 5 is driven by the first elastic element 8 to rotate toward the firing position. The above configuration, by configuring a first limiting hook 501 on the drive arm 5 and a second limiting hook 201 on the trigger 2, allows the drive arm 5 to be locked in the loaded position when the loading component moves forward to load a bullet after driving the drive arm 5 to the loaded position. By configuring the trigger 2 to rotate relative to the gun body 1, the second limiting hook 201 is disengaged from the first limiting hook 501. A first elastic element 8 is disposed between the drive arm 5 and the trigger 2, which drives the drive arm 5 to rotate toward the firing position when the second limiting hook 201 is disengaged from the first limiting hook 501. This allows the drive arm 5 to be driven by the trigger 2 to open the gas seal block 4 and the communication port 103 to fire the bullet when the loading block 3 is inserted out of the cartridge chamber 102.

[0035] In this embodiment of the utility model, the two ends of the drive arm 5 along its length are defined as the first end O1 and the second end O2. The position where the drive arm 5 connects to the gun body 1 is defined as the connecting end O3. The distance between the first end O1 and the connecting end O3 is less than the distance between the second end O2 and the connecting end O3. The airtight block 4 is located at the first end O1, and the first elastic element 8 is located at the second end O2. When the chamber block 3 moves backward, it abuts against the second end O2, causing the drive arm 5 to rotate and the airtight block 4 to tilt upward to close the communication port 103. After the chamber block 3 is inserted into the cartridge chamber 102, the trigger 2 flips backward, causing the drive arm 5 to rotate and the airtight block 4 to swing downward to open the communication port 103. The above configuration involves placing the airtight block 4 on the first end O1 and the first elastic element 8 on the second end O2. The distance between the first end O1 and the connecting end O3 is configured to be smaller than the distance between the second end O2 and the connecting end O3. This allows the airtight block 4 to quickly open the communication port 103 when the first elastic element 8 drives the airtight block 4 to swing down. At the same time, the sealing effect is better when the upper chamber block 3 drives the airtight block 4 to tilt up and close the communication port 103.

[0036] In this embodiment of the invention, a second elastic element 9 is provided on the airtight block 4. The second elastic element 9 is used to drive the airtight block 4 to move away from the communication port 103. By configuring the second elastic element 9 on the airtight block 4 to drive the airtight block 4 to move away from the communication port 103, the airtight block 4 can quickly disengage from the communication port 103 when the drive arm 5 rotates to open the communication port 103, resulting in a better firing effect.

[0037] In this embodiment of the utility model, the gun body 1 has an outer tube 107, a cartridge tube 108, and an air valve 109. The air valve 109 is located inside the outer tube 107 and partially extends out of the outer tube 107 and is connected to the cartridge tube 108. The air valve 109 and the outer tube 107 cooperate to form a compression chamber 101. The air valve 109 and the cartridge tube 108 cooperate to form a discharge chamber 102. The air valve 109 has a connecting channel 104 that connects the compression chamber 101 and the discharge chamber 102. A connecting port 103 is formed in the connecting channel 104. The airtight block 4 is at least partially accommodated in the connecting channel 104 and can move along the connecting channel 104 to open and close the connecting port 103. The above configuration is achieved by assembling the gun body 1 into an outer tube 107, a cartridge tube 108, and an air valve 109. The air valve 109 has a connecting channel 104 that connects the compression chamber 101 and the cartridge chamber 102. The airtight block 4 moves along the connecting channel 104 to open and close the connecting port 103, thus making the gun body 1 compact and reasonable.

[0038] In this embodiment of the invention, a first sealing ring 10 is provided on the airtight block 4 to abut against the cavity wall of the connecting channel 104. This arrangement, by configuring the first sealing ring 10 on the airtight block 4 to abut against the cavity wall of the connecting channel 104, ensures a tight and compact assembly between the airtight block 4 and the gun body 1, preventing air leakage during firing and thus avoiding any impact on the firing effect.

[0039] In this embodiment of the invention, the connecting channel 104 is inclined forward from bottom to top. This arrangement, by configuring the connecting channel 104 to be inclined forward from bottom to top, facilitates the ejection of the bullet, and under the same pressure, the bullet's firing velocity is faster.

[0040] In this embodiment of the invention, the connecting channel 104 is connected to the ejection chamber 102 via the air outlet 105. The front end of the air valve 109 extending from the outer tube 107 is connected to the rear end of the cartridge tube 108 for insertion of the loading block 3. A third sealing ring 11 is provided through one end of the loading block 3 inserted into the air valve 109. When the loading block 3 is inserted into the air valve 109, the third sealing ring 11 abuts against the cavity wall of the ejection chamber 102 and is located behind the air outlet 105. The above arrangement makes the air valve 109 compact and reasonable in structure.

[0041] In this embodiment of the invention, the air valve 109 is detachably and fixedly connected to the outer tube 107 and the spring tube 108, respectively. This arrangement facilitates the assembly and disassembly of the air valve 109.

[0042] In this embodiment of the invention, the gun body 1 further includes an inner tube 113 disposed within the outer tube 107, an air valve 109 disposed between the inner tube 113 and the compression block 6, and a trigger 2, a loading block 3, and a drive arm 5 disposed on the inner tube 113. The above arrangement facilitates the assembly and disassembly of the gun body 1.

[0043] In this embodiment of the invention, the chambering block 3 is slidably connected to the gun body 1. When the chambering block 3 exits the ejection chamber 102 and drives the drive arm 5 to rotate, it abuts against the drive arm 5 vertically. The chambering block 3 is provided with a guide groove 301, and the gun body 1 is provided with a guide strip 106 that slidably engages with the guide groove 301. The above arrangement, by configuring the chambering block 3 to be slidably connected to the gun body 1, ensures stable assembly and smooth sliding between the chambering block 3 and the gun body 1.

[0044] In other embodiments, the guide groove 301 is disposed on the gun body 1, and the guide bar 106 is disposed on the chamber block 3.

[0045] In this embodiment of the invention, the airtight block 4 is detachably and fixedly connected to the drive arm 5. This arrangement, by configuring the airtight block 4 to be detachably and fixedly connected to the drive arm 5, makes the airtight block 4 easy to install, remove, repair, and replace.

[0046] In this embodiment of the invention, a second sealing ring 12 is provided on the compression block 6 to abut against the inner wall of the compression chamber 101. This arrangement, by configuring the compression block 6 to have the second sealing ring 12 abutting against the inner wall of the compression chamber 101, prevents air leakage when the compression block 6 moves along the compression chamber 101 for pressurization, thus avoiding any impact on the pressurization effect.
