The trigger valve includes a valve bar, an air exhausting passage, an air guiding passage and a stopper. The stopper divides the valve body into an upper air chamber and a bottom air chamber. The upper air chamber is connected with the air chamber via the air guiding passage The bottom air chamber is connected with the upper air chamber via at least one connecting passage disposed in the upper bar portion. | 11-06-2008 |
| 20080290130 | MOVABLE CYLINDER DRIVING AIR PASSAGE OF NAIL GUN - A moveable cylinder driving air passage of a nail gun with a gun body, which includes a trigger valve having a valve bar; an air-in passage formed in the trigger valve connecting between an air collecting chamber and a main passage; an air-out passage formed in the trigger valve connecting between the main passage and external atmosphere; a stopper ring formed at an outside surface of the cylinder and slidably attached in the gun body; an air tank formed at an upper portion of the stopper ring; and a main chamber formed at a bottom portion of the stopper ring, the main chamber connects with the air-in and air-out passages. The main chamber is capable of collecting the high pressure air via the air-in passage to actuate the cylinder to move up while the valve bar is pressed, and exhausting the high pressure air via the air-out passage to actuate the cylinder to move down for reposition while the valve bar is released. | 11-27-2008 |
| 20090095787 | Transmission Mechanism for Electric Nail Gun - A transmission mechanism for an electric nail gun includes a linear transmission unit and a rotary transmission unit in a housing of the electric nail gun. The rotary transmission unit includes an electric driven driving wheel. The linear transmission unit includes a rack and a hitting bar. The hitting bar is disposed at a bottom of the linear transmission unit. The rack is in mesh with the driving wheel, slidably installed in the housing by a spring force, and configured to receive driving from the driving wheel and to drive the hitting bar to move linearly downward so as to hit a nail. | 04-16-2009 |
| 20090194573 | Actuator for Electrical Nail Gun - An actuator is arranged in a housing of an electrical nail gun. The actuator includes a sliding base, an external-running brushless direct current motor, a swing base and an electric driver. The sliding base is slidably disposed on an end of a located supporter which is positioned in the housing. The sliding base loads a spring and forms a hitting nail bar thereon. The motor has a stator and a rotator attached on an outer wall of the stator. A flywheel is driven by the motor and is configured to engage or disengage with/from the sliding base. The swing base is pivotally mounted on the housing. The swing base is adjacent to the sliding base and the supporter. The motor is installed in the swing base. The electric driver is attached to the housing and is adjacent to an end side of the swing base. The electric driver has a rod member driven by electricity. The rod member drives the swing base to swing to a first position where the flywheel meshes with the sliding base to thereby drive the sliding base to move downwards, and a second position where the flywheel disengages from the sliding base to thereby cause the sliding base to reposit. It is advantage to simplify the configuration of the actuator for the flywheel and is useful for the miniaturization of the electrical nail gun. | 08-06-2009 |
| 20100012699 | Control mechanism for Pneumatic Nail Guns - In a controlling mechanism for pneumatic nailer, the pneumatic nailer includes a leaf spring, a trigger, a trigger valve and a safety rod attached to a main body of the nailer. The control mechanism includes a control valve and a connecting rod. The control vale includes a valve plug adjacent to the safety rod. The connecting rod is engaged with the valve plug and the safety rod. The connecting rod extends to a position that is capable of being pressed by the leaf spring. The connecting rod is configured for driving the valve plug and the safety rod to move downwardly when the leaf spring press thereof, thereby controlling the pressurized air to drive the nail gun. As such, the valve plug can move in to a position that can to control the nail hitting action of the nail gun in advance so the stability of control increases. | 01-21-2010 |
| 20100193560 | Trigger Valve for Nail Gun - A trigger valve includes a valve base, a valve rod, a sliding portion and a shuttle valve. The valve base is disposed at a gun body of the nail gun between a compressed chamber and a main air valve of the nail gun. The valve rod is capable of being driven by a trigger of the nail gun to move so as to open or close high pressure air from the compressed chamber into the valve base. The sliding portion is capable of being driven by high pressure air to move to cause a safety slide rod of the nail gun producing a displacement along a hitting-nail direction. The shuttle valve is capable of being driven to move under control of the displacement of the sliding portion so as to open or close high pressure air from the valve base into the main air valve. | 08-05-2010 |
| 20110084111 | Braking and Driving Mechanism for Nail Gun - A braking and driving mechanism includes a guide plate, a driving rod, a magazine, and a pressing rod. The guide plate includes a longitudinal nail groove extending along a direction same to a nail driving direction of the nail gun. The longitudinal nail groove is communicated with a nail driving groove. The driving rod is slidably assembled on an end side of the guide plate along the nail driving direction. A stopping portion is formed on an end side of the driving rod. The magazine is transversely disposed on an end wall of the guide plate. An inner portion of the magazine defines a longitudinal guide groove for supplying nails. The longitudinal guide groove receives a plurality of nails therein and is communicated with the longitudinal nail groove. More than one nail pushing pieces capable of providing an elastic force are arranged in the longitudinal guide groove. The nail pushing pieces are configured for pushing the nails to pass through the longitudinal nail groove and enter into the nail driving groove one by one for shooting. The pressing rod consists of a bar shaped arm with its two opposite ends extending to respectively form a tongue portion and a pushing portion. A pivot portion is formed between the tongue portion and the pushing portion. The pressing rod is pivotably disposed in the magazine via the pivot portion. An elastic member for driving the arm to transversely press a main body of each of the nails is disposed on the pushing portion. If the number of remaining nails in the magazine is equal to a default number the elastic member drives the tongue portion to move to a position where the tongue portion can block the stopping portion such that the movement of the driving rod is braked. | 04-14-2011 |
| 20110114692 | Driving Device for Resetting Hitting Nail Bar of Pneumatic Nail Gun - A driving device for resetting a hitting nail bar of the pneumatic nail gun, which is mounted in a gun body including a main air chamber, a trigger valve, a hitting nail bar and a bottom cylinder chamber disposed therein is provided. The driving device includes a main gas channel and a sensing valve component slidably disposed in the main gas channel. The main gas channel communicates with the main air chamber and the bottom cylinder chamber via the trigger valve. The sensing valve component is controlled by the position of the hitting nail bar to be either opened or closed. The sensing valve component is opened on the condition that a reset state of the hitting nail bar is excluded, and the high-pressure air is introduced from the main air chamber into the bottom cylinder chamber to drive the hitting nail bar to move upwardly to reset rapidly. | 05-19-2011 |
