[0027] This embodiment provides a dust cover for a ball head pin, including:

[0028] A cover body 1, the cover body 1 includes a first connection port 11 and a second connection port 12. The first connection port 11 is used to connect to the ball pin, and the second connection port 12 is used to connect to the ball seat;

[0029] An oil storage member 2, the oil storage member 2 is installed on the cover body 1. The oil storage member 2 includes an oil storage cavity 21, an oil injection hole, and an oil outlet hole. The oil injection hole is in communication with the oil storage cavity 21, and the oil storage cavity 21 is in communication with the interior of the cover body 1 through the oil outlet hole.

[0030] Furthermore, the oil storage member 2 and the cover body 1 are of an integral structure.

[0031] Furthermore, the oil storage member 2 further includes:

[0032] A sealing plug 3, the sealing plug 3 is used to block the oil injection hole.

[0033] In this technical solution, the dust cover for the ball head pin can be made of nitrile rubber, which has excellent oil resistance, relatively high wear resistance, and good heat resistance. The dust cover is installed on the ball head pin for use. The first connection port 11 of the cover body 1 is snap-connected to the ball pin, and the second connection port 12 of the cover body 1 is snap-connected to the ball seat. The oil storage member 2 and the cover body 1 are designed as an integral structure.
