Shooting structure of a paint bullet gun ( = )

Abstract

A shooting structure of a paint bullet gun, including a gun body and a handle. A gunlock and a shot control unit are disposed in the gun body. A trigger unit is disposed in the handle for controlling the shot control unit. An activating chamber is formed in the gun body, in which the gunlock is slidably disposed. An annular shooting air reserving room is formed on outer circumference of the activating chamber. A first intake and a second intake are formed between the shooting air reserving room and the activating chamber. A vent is formed between the air source and the activating chamber. A first space and a second space are defined between the gun body and inner wall of the activating chamber. The first and second spaces are movable along with the reciprocally moved gunlock to be aligned with the first intake or the second intake and the vent. A front section of the gunlock is formed with an internal air duct. One end of the air duct extends to a front end of the gunlock, while the other end of the air duct extends to communicate with the first space.

1 . A shooting structure of a paint bullet gun, comprising a gun body and a handle, a gunlock and a shot control unit being disposed in the gun body, an air source serving to fill air into the gun body, a trigger unit being disposed in the handle for controlling the shot control unit which controls the gunlock to reciprocally move, whereby a paint bullet can be controllably dropped into the gun body and the air of the air source can be controlled to shoot the paint bullet, said shooting structure being characterized in that: 
 an activating chamber is formed in the gun body, one end of the activating chamber being connected with a barrel, the gunlock being slidably disposed in the activating chamber, a bullet-dropping port being disposed on the activating chamber near the barrel, an annular shooting air reserving room being formed on outer circumference of the activating chamber of gun body for reserving a certain amount of air, the air source supplying air for the shooting air reserving room, a first intake and a second intake being formed between the shooting air reserving room and the activating chamber to communicate the activating chamber with the shooting air reserving room, a vent being formed between the air source and the activating chamber to communicate the activating chamber with the air source; and    the gunlock is a bar body, a first space and a second space being defined between the bar body and inner wall of the activating chamber, the first space being movable along with the reciprocally moved gunlock to be aligned with the first intake, while the second space being movable along with the reciprocally moved gunlock to be aligned with the second intake and the vent, a front section of the gunlock being formed with an internal air duct, one end of the air duct extending to a front end of the gunlock corresponding to the bullet-dropping port, the other end of the air duct extending to communicate with the first space.    
   
   
       2 . The shooting structure of the paint bullet gun as claimed in  claim 1 , wherein two air reservoirs are respectively parallelly disposed on two sides of the activating chamber of the gun body, a front section of the air reservoir near the barrel communicating with a handle pressure regulator for adjusting the pressure coming from the air source into the air reservoir, the vent communicating the activating chamber with the air reservoir, the handle being arranged under the gun body near the handle pressure regulator, the trigger unit being disposed in the handle corresponding to the shot control unit, the trigger unit including a trigger, a linking plate and a spring, whereby the trigger can drive the linking plate to control the shot control unit.  
   
   
       3 . The shooting structure of the paint bullet gun as claimed in  claim 2 , wherein the shot control unit has a valve body and a piston body, the gun body being formed with a passage between the activating chamber and the air reservoir in parallel thereto, the valve body and the linking plate being accommodated in the passage, the piston body being fixed at one end of the activating chamber of the gun body opposite to the barrel, a rear plug body sealing the activating chamber.  
   
   
       4 . The shooting structure of the paint bullet gun as claimed in  claim 3 , wherein the valve body is formed with an internal cavity in which a valve rod is mounted, a middle section of the valve body being formed with several cuts communicating with the cavity, at least one air reservoir being formed with a passage communicating with the cuts, whereby part of the air in the air reservoir can enter the cavity, two ends of the cavity being respectively formed with a first ventiduct and a second ventiduct communicating with the interior of the piston body, the valve rod being formed with a first plug section and a second plug section respectively corresponding to the first and second ventiducts, one end of the valve rod being connected with the linking plate of the trigger unit, the trigger of the trigger unit being able to drive the valve rod to reciprocally move within the cavity, whereby the first plug section or the second plug section unblocks/blocks the first ventiduct or second ventiduct, the piston body being formed with an internal receiving passage in which a piston rod with a piston block is accommodated, a front end and a rear end of the receiving passage respectively communicating with the first and second ventiducts of the valve body, one end of the piston rod opposite to the piston block being connected with the gunlock.  
   
   
       5 . The shooting structure of the paint bullet gun as claimed in  claim 1 , wherein a first annular groove and a second annular groove are formed on the body of the gunlock, the first space and second space being defined between the first and second annular grooves and inner wall of the activating chamber, one end of the air duct of the gunlock extending to a section of the gunlock where the first annular groove is formed, this section being formed with several radial through holes communicating the air duct with the first space.  
   
   
       6 . The shooting structure of the paint bullet gun as claimed in  claim 5 , wherein several O-rings are inlaid in outer circumference of the body of the gunlock on two sides of the first and second annular grooves to airtight abut against inner wall of the activating chamber for avoiding leakage of air.
