[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] In the related art, the existing automobile rubber dust cover will be fatigued and damaged in five to seven years. As an important component for protecting the steering shaft, the automobile rubber dust cover is very troublesome to replace. It is necessary to remove the tire and the nut fixing the steering ball head, which will cost a lot of manpower and material resources. Therefore, the technical solution of the present application is produced. Figures 1 to 4 To elaborate.

[0029] Example 1

[0030] like Figure 1 to Figure 2 As shown, the rubber dust cover installation device described in the present invention is a strip-shaped design.

[0031] The automobile rubber dust cover installation device provided by the invention optimizes a traditional integral mold model into a strip-shaped design.

[0032] Material selection: The rubber dust cover is made of highly elastic and wear-resistant rubber, which has strong tensile properties and anti-aging ability.

[0033] Belt structure: The length of the rubber belt 1 is adjusted according to different vehicle models to ensure that it can completely cover the parts that require dust protection.

[0034] During installation, the end 2 of the rubber belt is covered layer by layer to the target part by spiral winding to form a continuous and closed protective layer.

[0035] Example 2

[0036] like Figure 3 As shown, the application of an oblique Z-shaped interface described in the present invention is intended to ensure that the connection of the strip-shaped rubber dust cover is tight and firm:

[0037] Interface design: The cross section 3 of the rubber belt is set to an oblique Z shape, and initial fixation is achieved through staggered bite.

[0038] Use of super glue: Evenly apply high-strength weather-resistant glue on the oblique Z-shaped joints. After the glue cures, the interface can withstand high-strength tensile and torsional stresses to ensure sealing and stability during use.

[0039] Example 3

[0040] like Figure 4 As shown, the purpose of the application of a concave-convex interface described in the present invention is to ensure that the connection of the strip-shaped rubber dust cover is tight and firm:

[0041] Interface design: The cross section 3 of the rubber belt is set to be concave and convex, and initial fixation is achieved through staggered bite.

[0042] Use of super glue: Evenly apply high-strength weather-resistant glue on the concave and convex joints 6. After the glue is cured, the interface can withstand high-strength tensile and torsional stress to ensure sealing and stability during use.

[0043] Example 4

[0044] like Figures 1 to 4 As shown, the double-layer spiral winding enhanced protection described in the present invention is intended to enhance the overall strength and durability of the dust cover:

[0045] First winding: The rubber belt 1 is wound around the installation part in a spiral manner to form the first layer of protection.

[0046] The second circle is symmetrically wound: on the basis of the first layer, the second layer is wound in the opposite direction so that the upper and lower layers of the rubber belt 1 form a symmetrical structure.

[0047] Bonding reinforcement: Use strong glue to bond the outside of the first layer to the inside of the second layer to further improve the overall stability and prevent delamination.

[0048] Example 5

[0049] like Figure 1 and Figure 5 As shown, a fixing method of a cable tie 7 described in the present invention is to install a special cable tie 7 at the concave arc portion 5 outside the dust cover:

[0050] Strap material: Made of high-strength nylon material with good wear resistance and toughness.

[0051] Installation method: The strap is fixed around the concave arc part 5 of the rubber dust cover, and the tightness is adjusted by adjusting the buckle to ensure the firmness of the dust cover under high-intensity working conditions.

[0052] Example 6

[0053] like Figures 1 to 5 As shown, a simple installation process described in the present invention. The installation device of the present invention is simple in design, and the user can complete the installation without removing the car tire and fixing the steering ball head nut, including the following steps:

[0054] A1. Clean the surface of the part to be replaced to ensure it is free of oil and debris.

[0055] A2. Fix the starting end of the rubber belt 1 at the replacement location and wrap it around the dustproof location layer by layer in a spiral shape.

[0056] A3. Apply strong glue to the Z-shaped interface 4 and wait for the glue to cure.

[0057] A4. After completing the first circle, continue to wrap the second circle in the opposite direction, and apply glue between the layers.

[0058] A5. Install a cable tie 7 on the outer concave arc portion 5 and adjust it to appropriate tightness.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
