Trigger safety for air gun and air gun containing the same

Abstract

A trigger safety for an air gun, including: a safety apparatus disposed on the body of an air gun and movable forward and backward, and a safety latch matching the safety apparatus to achieve activation and deactivation of the trigger safety. The safety apparatus further includes an assist device for assisting the safety apparatus to unlock the locked activation or deactivation state between the safety apparatus and the safety latch. This trigger safety ensures the security of the air gun, reduces the force required for deactivating or activating the trigger safety, and improves the efficiency of targeting and shooting the air gun.

The invention claimed is: 
     
         1 . A trigger safety for an air gun, comprising:
 a safety apparatus disposed on a body of an air gun and adapted to move forward and backward along the body of the air gun; and   a safety latch matching the safety apparatus to achieve activation and deactivation of the trigger safety; wherein   the safety apparatus further comprises an assist device for assisting the safety apparatus to unlock activation or deactivation state between the safety apparatus and the safety latch.   
     
     
         2 . The trigger safety of  claim 1 , wherein:
 the safety apparatus further comprises a safety bolt adapted to move forward or backward and a front slot and a rear slot that are disposed on the safety bolt and that match the safety latch;   the assist device further comprises a pushing rod disposed within the safety bolt and adapted to move forward or backward, a pushing-rod-resetting apparatus, and a projection on the pushing rod, an opening disposed inside or adjacent to the front slot and the rear slot and allowing the projection to extend through the opening; and   when the pushing rod is pushed forward, the projection extends through the opening around the slots to push the safety latch to an outside of the front slot or the rear slot.   
     
     
         3 . The trigger safety of  claim 2 , wherein:
 the safety latch further comprises a latch bulge and a latch-bulge-resetting spring;   the pushing-rod-resetting apparatus is a resetting spring; and   a rear end of the pushing rod extends from the rear end of the safety bolt, and a front end of the pushing rod is connected to the resetting spring.   
     
     
         4 . The trigger safety of  claim 2 , wherein a front end of the safety bolt is in a wedge shape comprising two tapered edges. 
     
     
         5 . The trigger safety of  claim 2 , wherein the safety latch is arranged beneath the safety bolt; and
 a rear sidewall of the projection on the pushing rod and a lower surface of the opening are tapered guide edges matching each other.   
     
     
         6 . The trigger safety of  claim 2 , wherein a guide column is disposed slantwise inside the safety bolt, a constraining guide groove is disposed on a central portion of the pushing rod corresponding to the guide column, and the constraining guide groove and the guide column are adapted to allow the pushing rod to be movably connected to the safety bolt. 
     
     
         7 . An air gun, comprising:
 a gun body;   a gas-compressing device disposed on the gun body;   a loading energy storage device;   a trigger; and   a trigger safety, the trigger safety comprising a safety apparatus disposed on the gun body and adapted to move forward and backward along the gun body and a safety latch matching the safety apparatus to achieve activation and deactivation of the trigger safety, and the safety apparatus further comprising an assist device for assisting the safety apparatus to unlock activation or deactivation state between the safety apparatus and the safety latch.   
     
     
         8 . The air gun of  claim 7 , wherein:
 the safety latch comprises a latch bulge and a latch-bulge-resetting spring;   the safety apparatus comprises a safety bolt adapted to move forward and backward and a front slot and a rear slot that are disposed on the safety bolt and that match the latch bulge;   the safety bolt is connected to the trigger via a linkage piece;   the assist device comprises a pushing rod disposed within the safety bolt and adapted to move forward or backward, a pushing-rod-resetting apparatus, and a projection on the pushing rod;   an opening is disposed inside or adjacent to the front slot and the rear slot and allowing the projection to extend through the opening; and   when the pushing rod is pushed forward, the projection extends through the opening around the slots to push the safety latch to the outside of the front slot or the rear slot.   
     
     
         9 . The air gun of  claim 8 , wherein:
 the safety latch is arranged beneath the safety bolt;   a guide column is disposed slantwise inside the safety bolt;   a constraining guide groove is disposed on a central portion of the pushing rod corresponding to the guide column;   the constraining guide groove and the guide column are adapted to allow the pushing rod to be movably connected to the safety bolt; and   a rear sidewall of the projection on the pushing rod and a lower surface of the opening are tapered guide edges matching each other.   
     
     
         10 . The air gun of  claim 8 , wherein:
 the gas-compressing device comprises a cylinder disposed inside the gun body, a piston back-and-forth movable inside the cylinder, a connecting rod connected to the piston, and a compressing handle hinged to the gun body and adapted to drive the connecting rod to move;   a rear end of the compressing handle comprises a wedge-shaped pressing part for pushing the safety bolt backward to deactivate the trigger safety and a depression for accommodating the front end of the safety bolt; and   a front end of the safety bolt is in a wedge shape having two tapered edges corresponding to a shape of the depression.
