[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Reference Figures 1 to 6 As shown, a vehicle gearbox dust cover comprises a gearbox housing 2, a handle 4 arranged above the gearbox housing 2, and a control lever 5 fixed to the bottom surface of the handle 4. A mounting hole is opened on the gearbox housing 2, and the control lever 5 is inserted into the mounting hole. A dust cover body 1 is sleeved on the rod body of the control lever 5 located above the gearbox housing 2. A dust cover base 3 abutting against the top surface of the gearbox housing 2 is fixed to the bottom end of the dust cover body 1. A ring-shaped connecting ring 10 is fixed to the bottom surface of the dust cover base 3. The connecting ring 10 is threadedly connected to the inner wall of the mounting hole. The top of the dust cover body 1 is tied to the rod body of the control lever 5 by a cable tie.

[0025] Through the threaded connection between the connecting ring 10 and the mounting hole of the gearbox housing 2, when it is necessary to disassemble and replace the dust cover main body 1, first use a knife to cut the cable tie that binds the dust cover main body 1, release the fitting connection between the dust cover main body 1 and the shaft of the control rod 5, then rotate the dust cover base 3, drive the connecting ring 10 through the dust cover base 3, and then loosen the connecting ring 10 from the mounting hole of the gearbox housing 2, and finally disassemble and replace the dust cover base 3 and the dust cover main body 1, so as to replace the installation method of the dust cover base in the prior art that is locked to the gearbox housing 2 by a buckle, thereby solving the problem that the dust cover base buckle is easy to break when the dust cover base is disassembled due to the installation structure of the dust cover base buckle.

[0026] However, in practice, during the process of replacing the dust cover body 1, the dust cover base 3 needs to be rotated, so the dust cover base 3 can only be rotated by pushing it manually, which is a laborious operation.

[0027] In view of this, in order to solve the above problems, refer to Figures 1 to 6It is worth noting that the top surface of the dust cover base 3 is provided with a labor-saving component for assisting the disassembly and assembly of the dust cover base 3;

[0028] The labor-saving component includes two push blocks 6 symmetrically arranged on both sides of the dust cover body 1, and a flip assembly is arranged at the bottom of the push block 6;

[0029] An arrow 8 is provided on the top surface of the dust cover base 3 on one side of the push block 6;

[0030] By setting the labor-saving components, when the dust cover base 3 needs to be disassembled and assembled, the push block 6 can be pushed along the direction of the arrow 8, thereby driving the dust cover base 3 to rotate. The rotation of the dust cover base 3 drives the connecting ring 10, causing the connecting ring 10 to be loosened from the mounting hole of the gearbox housing 2 and finally disassembled and replaced.

[0031] Further, refer to Figures 1 to 6 As shown, it is worth explaining that the flip assembly includes a rotating shaft 9 which rotates through the bottom of the push block 6, and a groove 7 which matches the push block 6 is provided on the top surface of the dust cover base 3. The bottom end of the push block 6 penetrates into one side of the groove 7, and the two ends of the rotating shaft 9 are respectively rotatably connected to the inner walls on both sides of the groove 7, and the inner wall of the groove 7 away from the rotating shaft 9 is provided with a chamfer.

[0032] By setting the flip assembly, after the dust cover base 3 is installed on the gearbox housing 2, the push block 6 can be rotated to flip it along the rotating shaft 9 into the groove 7. When the dust cover body 1 on the dust cover base 3 needs to be disassembled and replaced, the push block 6 can be flipped out of the groove 7 until the push block 6 abuts against the inner wall of one side of the groove 7. By setting the chamfer angle of the groove 7, it can be more convenient for the operator to flip the push block 6 out of the groove 7.
