Description

Technical Field

[0001] The utility model belongs to the technical field of dust covers, and particularly relates to a steering dust cover for an automobile. Background Art

[0002] The dust cover is located between the inner steering tie rod and the steering rack, forming a protective barrier to prevent dirt, dust, sand, water and other harmful particles from infiltrating into sensitive steering components. By blocking contaminants, the dust cover can ensure optimal performance and extend the service life of the steering system, minimizing wear on important components. Other designs can incorporate corrugated patterns to provide additional flexibility and durability.

[0003] However, in the existing dust covers, both ends of the dust cover are fixed to the steering mechanism of the automobile through hose clamps during installation. During actual use, the dust cover will expand and contract with the movement of the steering cross bar of the automobile. Prolonged use will cause the dust cover to be damaged, resulting in the outflow of the grease inside the dust cover, causing the internal parts of the automobile steering column to rub against each other, resulting in abnormal noise and component wear. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a steering dust cover for an automobile to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: It includes a housing, outer sleeve mouths provided at both ends of the housing, and outer grooves provided on the outer walls of the outer sleeve mouths. It further includes an inner liner provided inside the housing. Both ends of the inner liner are fixedly provided with inner sleeve mouths, and the two inner sleeve mouths are detachably connected to the two outer sleeve mouths respectively.

[0006] It should be noted in the solution that a first stopper and two second stoppers are fixed on the inner wall of the inner sleeve mouth. The first stopper and the two second stoppers are both annular, and the first stopper is located between the two second stoppers.

[0007] Further, it is worth noting that an annular inner groove is provided on the inner wall of the outer sleeve mouth, and a locking block fixed to the outer wall of the first stopper is embedded in the inner groove.

[0008] Compared with the prior art, the steering dust cover for an automobile provided by the utility model has at least the following beneficial effects:

[0009] (1) Through the arrangement of the inner liner and the inner sleeve mouth, during actual use, the inner liner is installed inside the housing, the inner sleeve mouths at both ends of the inner liner are abutted against the two ends of the housing, grease is put into the inner liner, and the housing and the inner liner are installed on the steering mechanism of the automobile, so as to achieve the purpose of double protection, so that the grease inside the inner liner will not flow out even if the housing is damaged.

[0010] (2) Through the arrangement of the second stopper and the first stopper, during installation, the first stopper and the two second stoppers are deformed under extrusion, making the inner sleeve opening closer to the steering mechanism of the vehicle and further enhancing the sealing performance of the inner liner.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4 , a steering dust cover for an automobile, comprising an outer shell 1, outer sleeve openings 3 provided at both ends of the outer shell 1, and outer grooves provided on the outer walls of the outer sleeve openings 3;

[0018] During the actual installation process, a hose clamp is used to install it into the outer groove on the outer wall of the outer sleeve opening 3, and the outer shell 1 is installed on the steering mechanism of the vehicle.

[0019] Furthermore, referring to Figures 1-4 as shown, it should be noted that an inner liner 2 is further provided inside the outer shell 1, both ends of the inner liner 2 are fixedly provided with inner sleeve openings 7, and the two inner sleeve openings 7 are respectively detachably connected to the two outer sleeve openings 3;

[0020] Through the settings of the inner container 2 and the inner sleeve opening 7, during actual use, the inner container 2 is installed into the outer shell 1, so that the inner sleeve openings 7 at both ends of the inner container 2 abut against the 3 at both ends of the outer shell 1. The grease is put into the inner container 2, and the outer shell 1 and the inner container 2 are installed on the steering mechanism of the vehicle, which can achieve the purpose of double protection, so that the grease in the inner container 2 will not flow out even if the outer shell 1 is damaged.
