  • Patent number: 9372047
    Abstract: Pressurized air from an air pressure bottle creates the firing motive force for game firearms. After accumulating sufficient pressure, the pressurized air is channeled to the gun chamber to achieve a firing objective. Using an application system for single firing, a purely mechanical firing control device is formed as an integral body to achieve single firing and continuous firing, and which is simply fitted with an auxiliary component to assist in achieving continuous firing. The auxiliary component is located in the swinging path of a cocking trigger. The select continuous firing clasp is pushed upward by the trigger and supports a jumping bar, which causes the jumping bar to lose its clasping retaining capacity on a firing tube to achieve a continuous firing operation.

  • Patent number: 8833353
    Abstract: An air gun firing operating system that uses compressed air to eject bullets by a purely mechanical device, and enables single firing or high-speed continuous firing. During the firing operation, the system uses a sliding shuttle tube that is able to slide back and forth in a linear displacement on a central axis between a bullet chamber and a cylinder. The sliding shuttle tube uses differential pressure variation in a pressure buffer chamber to achieve a stroke state that can be continuously changed, thereby achieving high-speed back and forth motion and continuous firing of bullets. The relevant driving position of a trigger device is provided with a sliding retainer, which is able to effect transient retaining of the sliding shuttle tube, thereby restricting the system for single firing, or discontinuing the retention to enable the system to be in a continuous firing operation state.

  • Publication number: 20120160226
    Abstract: The present invention provides an air gun firing operating system that uses compressed air to eject bullets by purely mechanical means, and enabling single firing or high-speed continuous firing. During the firing operation, the system uses a sliding shuttle tube that is able to slide back and forth in a linear line between a bullet chamber and a cylinder. The sliding shuttle tube is provided with a sliding column, and relative linear motion between the sliding column and the end opening of the cylinder determines critical opening and closing to obtain air pressure blasts, thereby achieving high-speed back and forth motion and continuous firing of bullets. The relevant driving position of a trigger device is provided with a sliding retainer, which is able to effect transient retaining of the sliding shuttle tube, thereby restricting the system for single firing, or opening the sliding retainer to enable a continuous firing operation.

  • Publication number: 20120160225
    Abstract: The present invention provides a mechanism for a magazine for spherical bullets able to rapidly clear bullets from the internal space of a retaining tube, thereby quickly preparing for reloading of bullets. The present invention primarily consists of a winding wheel operationally driving a drive device through a relational disposition therebetween, and uses a pullback cord fitted to the drive device to effect a rapid pulling operation, thereby swiftly driving the winding wheel to enable clearing of the internal space of the retaining tube and speedily completing preparation for reloading of bullets.

  • Patent number: 8203821
    Abstract: A multi-function electroshock gun includes a gun body that includes a barrel and a grip extending from the barrel, and a firing mechanism mounted in the gun body and operable to propel a projectile that is fired through the barrel. The multi-function electroshock gun further includes an electroshock unit that includes a battery mounted in the gun body, a set of exposed electrodes fixedly mounted to the gun body, and a discharge module. The discharge module is coupled electrically to the battery and the exposed electrodes and is capable of being activated to generate an electrical output signal at the exposed electrodes for administering electric shock by contact. The multi-function electroshock gun also includes a trigger mechanism mounted on the gun body and operable to activate the discharge module.

  • Publication number: 20110253119
    Abstract: A paint ball arraying device, especially used in a paint-ball gun to feed in spherical paint balls, keeps the paint balls intact and feeds the paint balls in a bore successfully. The arraying device utilizes a flexible loop-shape advancing belt, which is formed with an upright advancing side perpendicular to the bore after being assembled, and is spaced equally with multiple toggle rods, with a receiving slot being defined between every two toggle rods. By the upright advancing side, a space for feeding the external paint balls can be extended to load the paint balls in a large quantity. Furthermore, using the receiving slot, the paint ball contained can be maintained intact independently; the advancing side is upright and perpendicular to the bore that advancing force will not be divided into a component of force explicitly, thus, the paint balls can be successfully fed into the bore.

  • Publication number: 20110056468
    Abstract: A paint ball feeding buffer device, especially used for a paint-ball gun, is a magazine which loads a plurality of paint balls and provides for firing continuously. The magazine includes a roll-up device which restricts a stroke of an elastic advancing device, and the roll-up device is provided with a damping device which allows an initial stroke of the advancing device to be buffered, so as to prevent the paint balls from being squeezed, deformed, and ejected, by pressure which is released instantly.
