Air gun

Abstract

An air gun includes a main body in which a striker rod for striking and a gunlock for controlling the striker rod are arranged. The striker rod and the gunlock are driven by a rear block. The rear block is pushed by a thruster disposed in the main body. A controlling valve is disposed at front end of the main body. A trigger is arranged under the bottom of the main body for controlling the direction of airflow and the strike of the gunlock. The thruster is mounted in the main body right at the center of the rear block. The thruster includes a piston rod that is controlled by the controlling valve and axially movable out of the main body. One end of the piston rod extending out of the main body is right fixedly connected with the center of the rear block.

1 . An air gun comprising a main body, a striker rod for striking paint bullet and a gunlock for controlling the striker rod being longitudinally arranged in the main body in parallel to each other, the striker rod and the gunlock being driven by a rear block, the rear block being pushed by a thruster disposed in the main body, a controlling valve being disposed at front end of the main body for controlling direction of airflow, the controlling valve being connected with several pipelines for connecting with an air source and the thruster, a trigger being arranged under the bottom of the main body for controlling the direction of airflow of the controlling valve and the strike of the gunlock, said air gun being characterized in that thruster is mounted in the main body right at the center of the rear block, the thruster including a piston rod which is controlled by the controlling valve and axially movable out of the main body, one end of the piston rod extending out of the main body being right fixedly connected with the center of the rear block.  
   
   
       2 . The air gun as claimed in  claim 1 , wherein the main body is formed with an upper air chamber and a lower air chamber which are longitudinally arranged in parallel to each other, the striker rod and the gunlock being respectively disposed in the upper and lower air chambers, the thruster being disposed in the main body between the upper and lower air chambers, whereby the end of the piston rod of the thruster is right fixedly connected with the center of the rear block.  
   
   
       3 . The air gun as claimed in  claim 1 , wherein the thruster includes a cylinder disposed in the main body right at the center of the rear block, the piston rod being disposed in the cylinder, one end of the piston rod positioned in the cylinder having a piston, the other end of the piston rod extending out of the cylinder being right fixedly connected with the center of the rear block, two ends of the cylinder being respectively formed with two vents for connecting with the pipelines of the controlling valve, the piston being positioned between the two vents of the cylinder.  
   
   
       4 . The air gun as claimed in  claim 3 , wherein two sides of the main body are respectively formed with two channels extending to the vents, the vents radially respectively communicating with the channels, the pipelines of the controlling valve extending along the channels to connect with the vents.  
   
   
       5 . The air gun as claimed in  claim 3 , wherein two passages are respectively formed in the main body on two sides of the thruster, one end of each passage being connected with the vent, while the other end of the passage being connected with the pipeline of the controlling valve.  
   
   
       6 . The air gun as claimed in  claim 1 , wherein thruster has an air chamber directly formed in the main body right in alignment with the center of the rear block, the piston rod being disposed in the air chamber, one end of the piston rod positioned in the air chamber having a piston, the other end of the piston rod extending out of the air chamber being right fixedly connected with the center of the rear block, two ends of the air chamber being respectively formed with two vents for connecting with the pipelines of the controlling valve, the piston being positioned between the two vents of the air chamber.  
   
   
       7 . The air gun as claimed in  claim 6 , wherein two sides of the main body are respectively formed with two channels extending to the vents, the vents radially respectively communicating with the channels, the pipelines of the controlling valve extending along the channels to connect with the vents.  
   
   
       8 . The air gun as claimed in  claim 6 , wherein two passages are respectively formed in the main body on two sides of the thruster, one end of each passage being connected with the vent, while the other end of the passage being connected with the pipeline of the controlling valve.
