High-pressure pneumatic apparatus

Abstract

An improved high-pressure pneumatic apparatus can prevent gas leakage and allows quick assembling and is safe in use. The apparatus can be used with a barrel of an anti-riot or rescue tool gun, such as a catching net gun, a line-throwing gun or a riot gun, for supplying an intensive pressure for shooting in a very short time.

1 . An improved high-pressure pneumatic apparatus, comprising:
 an actuation gun, which mainly comprises a recess, a forwardly extended shaft slot in communication with the recess, a tension spring inserted in a bottom of the shaft slot while slightly protruding out of the shaft slot, and a trigger disposed at a distal end of the shaft slot, wherein the actuation gun at a front portion thereof comprises a barrel gas chamber that is in communication with a handle internal chamber and has a hole defined at a rear thereof in communication with the recess, in which a tube protrudes from an edge of the hole to form a tube slot so as to allow a strike pin and a spring to be inserted through the tube slot, and a cover having a through hole to cover the tube slot, and a plurality of protruding blocks is formed near an opening of the barrel gas chamber, and wherein an axle is disposed in the recess for supporting a movable strike arm that has one end thereof formed as a hook portion for being hooked with a hook of a shaft, which is disposed in the shaft slot and has a hole defined at a front end thereof for receiving a protruding pin of the trigger such that the shaft can be moved by the trigger, in which the tension spring resists against a bottom surface of the shaft;   a gas-pressure device, which comprises a valve cock unit centrally defining a valve hole and a recessed portion for receiving a resilient valve ball so that a recessed portion at a rear end of the tubular ball retainer abuts against and thereby positions the resilient valve ball, and a high-pressure gas bottle disposed in a latch bracket and positioned relative to the valve cock unit by inserting protrusions of the latch bracket into latch rails of the valve cock unit and rotating the latch bracket relative to the valve cock unit, wherein the tubular ball retainer comprises a plate bracket abutting against a front end of the latch bracket so as to position the high-pressure gas bottle in place, and the valve cock unit comprises a plurality of gun latch rails behind the latch rails; and   a recessed disk, which is connected with an inner tube of a gun tube and has a plurality of spaced tabs arranged along an outer periphery thereof;   whereby when the gun tube is connected with the gas-pressure device, the protruding blocks of the barrel gas chamber of the actuation gun are inserted into the gun latch rails of the valve cock unit respectively, and the valve cock unit is rotated and thus positioned relative to the actuation gun.
