DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described in detail below with reference to the drawings and embodiments.

[0020] As Figures 1-3As shown: An automotive tie rod assembly includes a tie rod 7, a ball joint pin 4, a ball seat 5, and a connecting nut 6. A dust-proof structure is also provided on the tie rod 7. The dust-proof structure includes a dust-proof outer cover 1 and a dust-proof inner cover 3. A first elastic column 8 is provided inside the dust-proof outer cover 1. The lower end of the first elastic column 8 is connected to a first connecting column 10. A second connecting column 2 is provided on the dust-proof inner cover 3. The second connecting column 2 penetrates the top surface of the dust-proof inner cover 3. The lower end of the second connecting column 2 is connected to a second elastic column 13. The first elastic column 8 extends beyond the top surface of the dust-proof outer cover 1. The dust-proof inner cover 3 is sleeved into the dust-proof outer cover 1. The second connecting column 2 abuts against the first connecting column 10. Push the dust-proof inner cover 3 inward. The first elastic column 8 and the second elastic column 13 contract. The snap ring 11 snaps into the groove inside the dust-proof outer cover 1, realizing the combination of the dust-proof outer cover 1 and the dust-proof inner cover 3.

[0021] A snap ring 11 is provided on the dust-proof inner cover 3. The snap ring 11 surrounds the second connecting column 2. The height of the snap ring 11 is lower than the part of the second connecting column 2 that extends beyond the top surface of the dust-proof inner cover 3. The snap ring 11 is made of an elastic material.

[0022] A groove is opened on the lower side inside the dust-proof outer cover 1. The size of the groove is the same as that of the snap ring 11. When the dust-proof outer cover 1 and the dust-proof inner cover 3 are snapped together, the snap ring snaps into the groove.

[0023] A first spring 9 is wound around the first elastic column 8, and a second spring 12 is wound around the second elastic column 13. When the dust-proof outer cover 1 and the dust-proof inner cover 3 are combined, the first spring 9 and the second spring 12 contract accordingly. When separated, the first spring 9 and the second spring 12 pop out, making it easier to disassemble.

[0024] Both the first elastic column 8 and the second elastic column 13 are made of an elastic material.

[0025] The working principle of this device is as follows: When combining the dust-proof outer cover 1 and the dust-proof inner cover 3, the dust-proof inner cover 3 is sleeved into the dust-proof outer cover 1. The second connecting column 2 abuts against the first connecting column 10. Push the dust-proof inner cover 3 inward. The first elastic column 8 and the second elastic column 13 contract, and the first spring 9 and the second spring 12 also contract accordingly. The snap ring 11 snaps into the groove inside the dust-proof outer cover 1, realizing the combination of the dust-proof outer cover 1 and the dust-proof inner cover 3. When disassembling the dust-proof outer cover 1 and the dust-proof inner cover 3, press down on the part of the first elastic column 8 that extends beyond the top surface of the dust-proof outer cover 1, push the second connecting column 2 downward, the snap ring 11 leaves the groove inside the dust-proof outer cover 1, the first spring 9 and the second spring 12 expand, and push the dust-proof inner cover 3 out of the dust-proof outer cover 1, realizing the disassembly of the two.

[0026] As described above, based on the embodiments as inspiration, through the above description, relevant staff can completely make various changes and modifications within the scope without departing from the idea of this invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
