Technical Field

[0001] This utility model relates to the technical field of grease dispensing equipment, specifically a handheld gear grease gun. Background Technology

[0002] A grease gun is a manual tool for applying grease to mechanical equipment. It can be equipped with either a metal nozzle (metal handle) or a flexible hose (flat nozzle). For convenient, spacious areas, the metal nozzle (metal handle) is preferable; for concealed or winding areas, the flexible hose (flat nozzle) is necessary. This tool is easy to operate, portable, and versatile, making it an essential tool for agricultural machinery operators and repair shops.

[0003] The existing sealing structure on grease guns requires multiple gear structures or transmission structures to cooperate in order to open and close the sealing structure. During the movement of the sealing structure, the gear structure or transmission structure may jam, which can easily damage the grease gun. In addition, traditional grease guns are difficult to disassemble and assemble, making grease gun maintenance troublesome. Utility Model Content

The pressure handle and the connecting piece are rotatably mounted with a transmission component through the fourth connecting hole and the third connecting hole, respectively. A return spring is provided on the inner wall of the pressure handle through the second connecting hole.

[0009] By adopting the above technical solution, the user installs a grease cartridge containing grease on the grease gun cap. Then, through the spring-loaded structure on the grease cartridge, the grease inside the cartridge is squeezed into the inlet. When the handle and the pressure handle are closed, the pressure handle drives the transmission component to move, which in turn drives the drive gear to rotate, thereby pushing the plunger rod to move. The plunger rod can block the connection between the inlet and the outlet pipe, preventing grease from being discharged from the outlet pipe. After the user separates the handle and the pressure handle, the pressure handle can be reset by the return spring, which in turn drives the transmission component to rotate the drive gear, allowing the plunger rod to move towards the pressure handle, connecting the inlet and outlet pipes. The grease inside the cartridge can then enter the outlet pipe, and finally, the grease is discharged from the outlet pipe.

[0010] Preferably, the oil inlet is connected to the oil outlet pipe, the size of the oil outlet pipe is adapted to the size of the plunger rod, the oil outlet pipe and the plunger rod are slidably connected, one end of the plunger rod is provided with teeth, and the drive gear meshes with the teeth on the plunger rod.

[0015] By adopting the above technical solution, the transmission component, consisting of a round hole, a third connecting hole, and a fourth connecting hole, can be stably installed between the connector and the pressure handle. During the opening and closing process of the handle and the pressure handle, the transmission component can drive the drive gear to rotate. Rivets are provided through the first connecting hole, the second connecting hole, the third connecting hole, and the fourth connecting hole. A riveting machine connects the connecting plate, the pressure handle, the transmission component, the connector, and the drive gear. The limiting groove on the transmission component allows the rivet on the first connecting hole to be exposed to the outside, facilitating the installation and removal of the rivet on the first connecting hole.

[0016] Preferably, a mounting hole is provided at the middle position on one side of the pressure handle, and the pressure handle is rotatably connected to the connecting plate through the mounting hole and the second connecting hole.

[0017] By adopting the above technical solution, the pressure handle is stably installed on the connecting plate through the mounting hole and the second connecting hole, and the pressure handle forms a fulcrum with the mounting hole and the second connecting hole, so that the pressure handle can rotate smoothly on the connecting plate.

[0018] Preferably, a fixing hole is provided at the bottom of one side of the handle, and a fixing ring is provided at the bottom of the handle through the fixing hole.

[0019] By adopting the above technical solution, after the handle and pressure handle are closed, the user can use the fixing ring on the handle to lock the pressure handle, thus keeping the grease gun in a blocked state.

[0020] Preferably, the grease gun cover has vent holes on both sides of its top, and the grease gun cover is connected to an vent valve through the vent holes.

[0021] By adopting the above technical solution, the exhaust valve is stably installed on the grease gun cover through the exhaust hole, preventing the exhaust valve from falling off the grease gun cover, and the exhaust valve is connected to the grease cylinder through the exhaust hole.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the handheld gear grease gun, through the cooperation between the pressure handle and the transmission component, enables the pressure handle to drive the drive gear to rotate, thereby driving the plunger rod to move. The structure formed by assembling the pressure handle, transmission component, drive gear and plunger rod is relatively simple and not prone to jamming, which can prevent the grease gun from being damaged. At the same time, the grease gun is relatively easy to disassemble and assemble, which facilitates the maintenance of the grease gun. Attached Figure Description
