Technical Field

[0001] The utility model relates to the technical field of air guns, in particular to an air gun firing and safety structure. Background Art

[0002] An airgun is a general term for firearms that fire projectiles using pressurized gas. These are light weapons that don't use gunpowder, instead relying on compressed air or gas pressure to eject the projectile. They primarily consist of a cylinder back cover, hammer spring, hammer, cylinder, air chamber, and a firing and safety mechanism. The firing mechanism ensures proper firing, while the safety effectively prevents accidental discharge and injury. Currently available firing and safety mechanisms are complex, increasing costs. Summary of the Invention

[0003] In order to solve the above technical problems, the utility model provides an air gun firing and safety structure, which can simplify the structure and reduce costs.

[0004] Its technical solution is as follows: an air gun firing and safety structure, characterized in that it includes a wrench, a sear and a safety mechanism, the wrench is connected to the wrench pin by rotation, the middle part of the sear is rotatably connected to the sear pin, one end side of the sear is used to resist and block the hammer, and the lower part presses the sear spring, the wrench is provided with a transmission head at one end near the sear and the transmission head is located below the other end of the sear, the safety mechanism includes a safety pin, a steel ball and a safety spring, one end of the safety pin is provided with two steel ball grooves corresponding to the steel balls and arranged at intervals, corresponding to the safety on position and the safety off position respectively, a wrench groove corresponding to the wrench is provided below the other end of the safety pin, the safety spring is clamped in the limit groove of the machine base, when the safety pin is moved horizontally to the safety off position, the wrench is limited by the safety pin and cannot be detent to detent the wrench, when the safety pin is moved horizontally to the safety on position, the wrench groove leaves a position for the wrench so that the wrench can be smoothly detent to complete the shooting.

[0005] It is further characterized in that the lower end of the sear spring is sleeved on a guide post fixed on the machine base;

[0006] The sear and the hammer are matched with each other on an inclined surface.

[0007] After adopting the utility model, a safety mechanism consisting of a safety pin, a steel ball and a safety spring is adopted. The steel ball can be used to fix the safety pin in the safety on position and the safety off position without human interference, so that the wrench can be smoothly pulled or the wrench cannot be pulled, and shooting is completed or accidental discharge is prevented. The overall structure is simple and the cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] See Figures 1 to 3 As shown, an airgun firing and safety structure includes a wrench 1, a sear 2, and a safety mechanism 3. The wrench 1 is rotatably connected to a wrench pin 4. The middle portion of the sear 2 is rotatably connected to the sear pin 5. One end of the sear 2 is used to support and block the hammer 6, and the lower portion presses the sear spring 7. A transmission head 1-1 is provided at the end of the wrench 1 near the sear 2, and the transmission head 1-1 is located below the other end of the sear 2. The safety mechanism 3 includes a safety pin 3-1, a steel ball 3-2, and a safety spring 3-3. One end of the safety pin 3-1 has two steel ball grooves 3-4 corresponding to the steel ball 3-2 and arranged at intervals, corresponding to the safety open position A and the safety closed position B, respectively. The other end of the safety pin 3-1 has a wrench groove 3-5 corresponding to the wrench 1 below. The safety spring 3-3 is clamped into the limit groove of the machine base 8 and acts as a limiting spring. The lower end of the sear spring 7 is sleeved on a guide column fixed to the machine base 8, and the sear 2 and the hammer 6 are matched with each other at an angle. Figure 11 is

[0012] The working principle of the air gun is explained in detail below.

[0013] In the non-hang-up state, the sear 2 does not press against the hammer 6. The hammer 6 is pushed forward against the valve stem of the air chamber component 10 by the action of the hammer spring 9. The upper surface of the sear 2 is pressed against the hammer 6 by the action of the sear spring 7. At this time, pulling the wrench 1 has no effect. In the hang-up state, that is, Figure 2In the state shown, the hammer 6 is pulled back to compress the hammer spring 9, and the sear 2 is acted upon by the sear spring 7 to spring upward, and the inclined surface at the end of the sear 2 fits and locks with the inclined surface of the hammer 6. At this time, the wrench 1 needs to be pulled to release the hammer 6; to pull the wrench 1, the safety must be in the on state. When the safety pin 3-1 moves to allow the steel ball 3-2 to fit into the steel ball groove 3-4 at the safety on position A, the steel ball 3-2 is acted upon by the safety spring. At this time, the safety pin 3-1 cannot move freely left and right without human intervention, and the wrench groove 3-5 leaves space for the wrench 1. At this time, the wrench 1 is pulled, and the wrench 1 rotates to allow the transmission head 1-1 to rotate. The end of the sear 2 is hit to lift it, and the other end is pressed down, so that the hammer 6 is no longer blocked and the hammer 6 is released. The hammer 6 is pushed forward by the hammer spring 9 and hits the valve stem of the air chamber component 10, releasing the gas in the air chamber component 10 and achieving the firing of the bullet. When the safety pin 3-1 moves to allow the steel ball 3-2 to be stuck in the steel ball groove 3-4 at the safety opening position B, the safety pin 3-1 cannot move freely left and right without human intervention. The wrench groove 3-5 is offset from the wrench 1. The wrench 1 is blocked by the safety pin 3-1 and cannot be pulled, thereby failing to release the hammer, achieving the purpose of the safety. The structure of the present application can achieve the firing and safety of the air gun at a relatively low cost.
