A paintball gun is to directly shoot a paintball by using pressurized air to avoid the fast movement of a hammer protruding from a barrel from hurting the hand of a user. A low-pressure regulator is turned to block a port of the barrel to prevent the pressurized air from entering into the barrel to avoid hurting people by accidentally pulling the trigger.
1. A paintball gun comprising a frame coupled with a pressurized air flask; a barrel being provided to the frame; a paintball drop hole being disposed at a top end of the barrel, the barrel being connected to an air storage chamber; a port and a keyhole being provided between the air storage chamber and the barrel; the air storage chamber connecting through the pressurized air flask; and a trigger being disposed to the frame, and characterized in that:
a T-valve being provided inside the frame to control the passage of low-pressure air;
a sticker being disposed in the barrel; an opening being provided to a front edge of the spool; a piston being inserted into the opening; a spring being disposed between the piston and the spool; both the spool and the piston being respective provided with through holes connecting through their outer edges; and a through channel being provided at a rear end of the spool; and
a low-pressure regulator being provided inside the air storage chamber, the low-pressure regulator comprising a block therein;
thereby, the T-valve controlling admission for the low-pressure air to enter into the through channel once the trigger being pulled to push the piston forward and to advance a paint ball; the pressurized air leaving the air storage chamber to pass in sequence through the port, the opening of the spool, the through hole of the spool, the through hole of the piston to shoot the paintball; the low-pressure regulator being turned to plug the port for preventing the pressurized air from entering into the barrel through the air storage chamber to avoid hurting people by accidentally pulling the trigger.

(a) Field of the Invention
The present invention relates to a paintball gun, and more particularly, to one that applies pressurized air to directly fire a paintball, having the pressurized air passing through a spool, an opening and a through hole of a piston, and has a port blocked by turning a low-pressure regulator to avoid hurting people by accidentally pulling a trigger.
(b) Description of the Prior Art
Survival game in jungle is quite popular sport, and a use of a paintball gun is the essence in the game. To mitigate the risks of using the paintball gun, a flask filled with pressurized air is essentially used as the motive power to shoot the paintball gun. As illustrated in
The primary purpose of the present invention is to provide a paintball gun that applies pressurized air to directly fire the paintball. To achieve the purpose, a T-valve is provided in a frame of the paintball gun to control the passage of low-pressure air; a spool is also provided in a barrel of the frame with an opening disposed at its front end and a piston is inserted into the opening; a spring is provided between the piston and the spool, both the piston and the spool are each provided with a through hole connecting to their respective outer edges; a through channel is disposed at the terminal of the spool; and a low-pressure regulator is provided in an air storage chamber and adapted with a block. When the trigger is pulled, the T-valve admits the low-pressure air to enter into the through channel to push the piston and to advance the paintball while the pressurized air passes from the air storage chamber in sequence through the port, the spool, the opening and the through hole of the piston to fire the paintball. By having the pressurized air to directly fire the paintball, there would be no fast move by the hammer protruding out of the barrel, thus there is not chance that the hand of the user to get hurt. When the low-pressure regulator is turned to block the port, it stops the pressurized air in the air storage chamber from entering into the barrel, thus to prevent accidentally pulling the trigger to hurt somebody.
The spool (2) disposed in the terminal of the barrel (11) has an opening (21) at the front edge of the spool (2). A piston (22) is inserted into the opening (21) to block the opening (21) of the spool (2). A spring (221) is disposed between the piston (22) and the spool (2). Two through holes (23), (24) are respectively provided to the spool (2) and the piston (22) to connect through their respective outer edges. A through channel (25) is disposed at the rear end of the spool (2) to connect through the lower-pressure air transmitted by the air outlet way (184).
The low-pressure regulator (3) is turned to be disposed at the terminal of the air storage chamber (13). The low-pressure regulator (3) has on its circumference provided in recess a groove (31), and its front end, a block (32).
When in use as illustrated in
To avoid pulling the trigger (17) by accident, the low-pressure regulator (3) is turned, as illustrated in
