[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a self-lubricating low-friction pin, comprising a pin body, wherein a liquid spraying assembly is fixedly connected to the inner ring surface of the pin body, and a pusher head is installed on the side surface of the pin body.

[0008] A support rod is fixedly connected to the inner ring surface of the main body of the pin, a nut is limited and snapped onto the inner ring surface of the support rod, and a threaded rod is limited and inserted into the inner ring surface of the nut.

[0009] A knob handle is installed on the side surface of the threaded rod, a piston plate is locked to the inner ring surface of the pin body, a connecting plate is installed on the side surface of the piston plate, and a protective baffle is locked to the outer ring surface of the pin body.

[0010] The present invention further illustrates that a piston push plate is installed on the side surface of the threaded rod, and the piston push plate and the liquid spraying assembly are structurally compatible.

[0011] Using the above technical solution, the piston pusher plate, which is structurally compatible with the liquid spraying component, allows the user to easily compress air inside the liquid spraying component after pushing the piston pusher plate.

[0012] The present invention further explains that a pull ring is inserted into the inner ring surface of the connecting plate, and the pull ring is connected between the connecting plate and the piston plate.

[0013] Using the above technical solution, the pull ring connecting the connecting plate and the piston plate makes it easy for the user to pull the piston plate.

[0014] The present invention further explains that the inner ring surface of the pin body is provided with a snap-fit ​​opening, and the size of the snap-fit ​​opening and the piston plate are matched.

[0015] The above technical solution features a snap-fit ​​opening that matches the size of the piston plate, which facilitates the user's snap-fit ​​operation of the piston plate.

[0016] This utility model further illustrates that the outer ring surface of the spraying assembly is limited and snapped with a spraying head, and the number of spraying heads is multiple.

[0017] The above technical solution, which includes multiple spray heads, facilitates efficient deployment of the lubrication head by the user.

[0018] This utility model further illustrates that the nut is connected between the support rod and the main body of the pin, and the support rod is arranged around the nut as the center point.

[0019] The above technical solution, with the support rod arranged around the nut as the center point, facilitates stable connection and use of the nut by the user.

Through the coordinated use of the pin body, protective baffle, pull ring, connecting plate, piston plate, spray head, spray assembly, push head, threaded rod, knob handle, nut, support rod, piston push plate, and snap-fit ​​opening, it facilitates efficient self-lubrication of the pin. To use self-lubrication, the user inserts the pin body into the desired installation position and rotates the knob handle to rotate the threaded rod. The nut's limiting action pushes the piston plate, pressurizing the spray assembly. The spray head dispenses a small amount of lubricating oil, applying it to the outer surface of the pin body. This efficient self-lubrication satisfies the user's needs.

[0022] This utility model provides a self-lubricating, low-friction pin. With the addition of a piston plate, and after the user inserts the piston plate onto the pin body, the user can efficiently use and carry the pin through the connecting plate and the pull ring that engages the inner ring of the connecting plate. This allows the user to conveniently carry and use the pin, thus meeting the user's need for easy portability. Attached Figure Description
