Abstract: A paintball gun having an internal pressure regulator is provided. The paintball gun includes a body, a launching tunnel, a rear lead shaft, the pressure regulator, and a back cover. A hollow barrel of the body allows the launching tunnel and the rear lead shaft to be accommodated successively therein. The pressure regulator is received in the rear lead shaft. The back cover is screwed to the body. Thereby, pressurized air coming from a gas cylinder is directly introduced to the pressure regulator so as for the paintball gun to dispense with any external air duct. Thus, the paintball gun poses no risk of duct burst and requires less assembling operation and fewer fixtures, thus reducing manufacturing costs.

Abstract: In one embodiment, a striking apparatus of a paintball gun is provided. The striking apparatus is received in a receiving chamber of a gun body. The gun body has a screw-jointing hole for being screwed and fixed to the striking apparatus. The striking apparatus includes a sleeve, a striking unit, a valve, and a pressure adjuster. The striking unit and the valve are received in the sleeve in sequence, and then the pressure adjuster is screwed to the sleeve. Being a unitary structure, the striking apparatus can be separated from the gun body completely and directly, and thus is easy to disassemble, maintain, and assemble.

Abstract: Provided is a shot sensor hooping device for a paintball gun, wherein a shot sensor has an insertion portion and a top end ring. The insertion portion is connected to a receiving hole of a gun body. The shot sensor hooping device includes: a hooping ring disposed above the receiving hole of the gun body; an operation unit disposed on a side of the hooping ring; and a hooped portion disposed between the insertion portion and the top end ring of the shot sensor and corresponding in position to an inner wall of the hooping ring and enclosed therein. The shot sensor hooping device enables the coupling and decoupling of the shot sensor and the gun body to be performed easily and quickly without operating any tool by hand.

Abstract: A paintball sensor installing and positioning structure includes a sensor unit screwed to the bottom end of a paintball dropping conduit. A transmitting end and a receiving end of the sensor unit are received respectively in receiving grooves bilaterally provided on the paintball dropping conduit. Positioning elements protruding from the bottom end of the paintball dropping conduit correspond in position to positioning recesses in a gun body to provide secure positioning. A pin at a lower portion of the sensor unit is inserted in a socket of the gun body. Gas inlet ducts provided in the inner wall of the gun body are separate from a paintball dropping port of the paintball dropping conduit such that gas need not pass through the paintball dropping conduit. Hence, corresponding gas ducts can be connected regardless of the precision with which the paintball dropping conduit is installed in the gun body.

Abstract: A firing structure of a paintball marker includes a marker body and a firing cylinder. The marker body includes a barrel with mutually communicating first and second gas chambers. A stop edge is formed in the barrel at a junction between the first and second gas chambers. An O-ring is embedded in an inner wall of the barrel at a position inside the second gas chamber. The firing cylinder and a rear guide rod are put sequentially into the gas chambers. The firing cylinder has an outer periphery formed with a stop portion in the first gas chamber. The stop portion has a front edge mounted with a buffer washer corresponding in position to the stop edge of the barrel and having a planar surface. Thus, the process yield of the marker body can be increased, and the firing cylinder remains stable in high-speed action regardless of its position.

Abstract: A hidden sensor structure for a paintball gun is to secure a loader unit on a hopper of a barrel. A loader is used to hold against the loader unit. The loader unit has arcuate slots to receive resilient stoppers therein, with studs protruding from the resilient stoppers to extend into the hopper. A sensor has an emission end, a receiving end, and a socket. The sensor is coupled to the loader unit from the bottom of the barrel, with the emission end and the receiving end inserting into two troughs formed on two sides of the load unit and the socket engaging with a fixture of the loader unit.
