Description

Technical Field

[0001] The utility model relates to the technical field of steering gear dust cover, in particular to a waterproof steering gear dust cover. Background Art

[0002] The main function of the automobile steering gear dust cover is to prevent dust from entering the connection between the steering gear and the steering column. Referring to the Chinese patent application number "201320250168.9" "A steering gear dust cover", the patent proposes that the existing steering gear dust cover is prone to deformation after long-term use due to long-term external force, which greatly reduces the sealing between the dust cover and the steering gear, making it easy for dust to enter the steering gear. However, there are still problems such as inconvenience in installation and disassembly, as well as the defect of poor waterproof effect. In this regard, we propose a waterproof steering gear dust cover to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a waterproof steering gear dust cover, which solves the problems raised in the above-mentioned background technology.

[0004] To achieve the above purpose, the utility model is implemented by the following technical solutions: a waterproof steering gear dust cover, including an upper cover and a lower cover, both ends of the upper cover and the lower cover are fixed with assembly plates, a plurality of positioning bolts are arranged inside the two assembly plates, and the positioning bolts are matched and fixedly connected as a whole;

[0005] An upper clamping ring is fixedly mounted on the end of the upper sealing sleeve away from the mounting plate, and a lower clamping ring is fixedly mounted on the end of the lower sealing sleeve away from the mounting plate.

[0006] Preferably, a sealing ring 1 and a sealing ring 2 are fixedly installed inside the upper clamping ring and the lower clamping ring respectively.

[0007] Preferably, an annular sheet is fixedly mounted inside the two assembly plates, and a sealing sheet is fixedly mounted outside the annular sheet to ensure the sealing performance between the upper seal and the lower seal.

[0008] Preferably, a plurality of reinforcing sheets are fixedly installed inside the upper and lower envelopes, the plurality of reinforcing sheets have the same shape and are all semi-annular, and the plurality of reinforcing sheets are symmetrically distributed inside the upper and lower envelopes.

[0009] Preferably, positioning frames are fixedly installed inside the upper and lower envelopes, and multiple elastic protection frames are fixed on the sides of the positioning frames. Protective pads are fixed on one side of the multiple elastic protection frames close to the inner walls of the upper and lower envelopes.

[0010] Preferably, the plurality of elastic protection frames are symmetrically distributed inside the upper and lower envelopes, and a distance is left between the elastic protection frames and the inner walls of the upper and lower envelopes.

[0011] The utility model provides a waterproof steering gear dust cover. Compared with the prior art, it has the following beneficial effects:

[0012] (1) The waterproof steering gear dust cover can be easily disassembled and maintained by the arrangement of the upper cover and the lower cover. Meanwhile, the reinforcement sheet can be arranged to support the interior of the upper cover and the lower cover, thereby preventing the upper cover and the lower cover from being deformed due to long-term use, thereby improving the service life of the dust cover and the convenience of disassembly and assembly.

[0013] (2) The waterproof steering gear dust cover is provided with a positioning frame and an elastic protective frame. When the dust cover is in use, as the upper cover and the lower cover are compressed and deformed, the elastic protective frame can be compressed and deformed, pressing the outer protective pad to contact the upper cover and the lower cover, thereby reducing the contact between the steering column and the steering gear and the upper cover and the lower cover, and improving the protective effect of the dust cover.
