[0002] An air gun is a firearm that uses pressurized gas as a power source to fire projectiles. Generally, the mechanism for preventing accidental discharge of an air gun from vibration relies on a safety. With the safety off, the gun is relatively safe. However, with the safety on, if the gun falls out of the hand, there is a risk of accidental discharge, posing a certain safety hazard. Therefore, some air guns are specially designed with corresponding mechanisms to prevent accidental discharge of the gun, but their structure is complex and the cost of use is high.

[0020] See Figure 1 , Figure 2 , Figure 3 As shown, an anti-vibration trigger mechanism includes a gun body 1, in which a trigger 2 and a hammer 3 are installed. The trigger 2 is a translational structure. Specifically, a horizontal guide groove 4 is installed on the gun body, and a guide block that cooperates with the horizontal guide groove 4 is installed on the side of the trigger 2, so that the trigger 2 can only move along the horizontal guide groove 4 to achieve translation.

[0021] The trigger 2 includes a pressing part, an intermediate connecting rod, and an end mounting seat. The end mounting seat is arranged above the intermediate connecting rod and the first rotating shaft 5 is installed on the end mounting seat. The first rotating shaft 5 is rotatably connected to the middle of the linkage rod 6. One end of the linkage rod 6 is provided with a first rocker arm 6-1 that abuts the trigger return spring 7, and the other end is provided with a second rocker arm 6-2. The hammer 3 is rotatably connected to the second rotating shaft 8 installed on the gun body 1. The bottom of the linkage rod 6 abuts against the pin 9 installed on the hammer 3. The lower part of the linkage rod 6 is provided with a makeshift groove that cooperates with the pin 9. A blocking buckle 10 is installed above the hammer 3. The blocking buckle 10 is rotatably installed on the third rotating shaft 11 with a torsion spring, and a blocking groove is provided on the upper part of the hammer 3.

[0022] The pin 9 is connected to one end of a tension spring 12 , and the other end of the tension spring 12 is connected to a hanging rod 13 fixed to the gun body 1 , for resetting the hammer 3 after falling back. A top block 16 is provided below the pin 9 .

[0023] A fixing seat 14 is provided above the middle connecting rod, and a spring fixing plate 15 connected to one end of the return spring 7 is provided in the fixing seat 14. A convex head is provided at the lower part of the first swing arm 6-1 to engage with the other end of the return spring. A limiting groove is provided on the fixing seat 14 to cooperate with the end mounting seat to limit the movement of the trigger 2.

[0024] The following is a detailed description of the air gun principle:

[0025] See Figure 4 As shown, it is in the initial state at this time, and the trigger 2 has not been pulled;

[0026] See Figure 5 As shown, the trigger 2 is pulled, and the trigger 2 drives the linkage rod 6 to move backward. The linkage rod 6 abuts the pin 9 and causes the hammer 3 to fall backward. At the same time, one end of the second pendulum rod 6-2 of the linkage rod 6 begins to rise, and the first pendulum rod 6-1 squeezes the return spring 7;

[0027] See Figure 6 As shown, continue to pull the trigger 2, the hammer 3 falls back and the top block 16 starts to push up the linkage rod 6, and at the same time the second swing rod 6-2 pushes the blocking buckle 10 upward, and the pin 9 is ready to fall off from the clearance groove of the linkage rod 6;

[0028] See Figure 7 As shown, the pin 9 and the clearance groove of the linkage rod 6 are completely detached, and the hammer is ready to rotate clockwise under the action of the tension spring 12. The top block 19 continues to push up the linkage rod 6, allowing the second rocker 6-2 to continue to push up the blocking buckle 10, so that it will not affect the hammer 3;

[0029] See Figure 8 As shown, the hammer 3 rotates clockwise and strikes the valve 20. During the entire process, the blocking buckle 10 is always in the raised state and does not interfere with the striking process.

[0030] After the trigger 2 is released, the trigger 2 and the linkage rod 6 are reset under the action of the reset spring 7.

[0031] See Figure 9 As shown, if the trigger 2 is not pulled, the hammer 3 falls back under vibration, and the blocking buckle 10 rotates counterclockwise and flips down under the force of the torsion spring, and is stuck in the blocking groove to block the hammer. The hammer cannot hit the valve, which plays a role of insurance.
