Description

Technical Field

[0001] The utility model relates to the field of automobile parts, in particular to a dustproof and leakproof protective sleeve. Background Art

[0002] The drive shaft dust cover is a component of the automobile drive shaft. It is generally made of synthetic rubber and is used to be installed on the outside of the star-shaped sleeve of the drive shaft to form a closed space to prevent dust and leakage. In order to save production materials, the existing dust cover is modified from a multi-peak to a single peak. However, in actual use, the entire cover is black. When the outer wall of the cover has unpenetrated damage, it is not easy to find during vehicle maintenance. Therefore, during the subsequent use of the vehicle, the damage gradually expands and even penetrates, making it impossible for the cover to form a sealed space, affecting the subsequent use of the vehicle.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-4 A dustproof and leakproof protective cover shown in the figure includes a single-peak dust cover 1, and the two ends of the single-peak dust cover 1 are respectively provided with a large port 3 and a small port 2 for sleeved on the shaft head and the shaft rod, and the interiors of the single-peak dust cover 1, the small port 2 and the large port 3 are respectively provided with a plurality of display threads 9 for highlighting damage, and the plurality of display threads 9 are all curved, and the inner walls of the small port 2 and the large port 3 are respectively provided with a first sealing ring 6 and a second sealing ring 7 for filling the gap.

[0021] Specifically, the small port 2, the single-wave-peak dust cover 1 and the large port 3 are arranged in sequence, the small port 2, the single-wave-peak dust cover 1, the large port 3 and the plurality of display threads 9 are an integral structure formed in one piece, the plurality of display threads 9 are arranged in an annular shape at equal intervals inside the single-wave-peak dust cover 1, and the plurality of display threads 9 are arranged in the middle part near the single-wave-peak dust cover 1, the small port 2 and the large port 3.

[0022] Furthermore, the single-peak dust cover 1, the small port 2 and the large port 3 are all made of synthetic rubber, which is black in color. The display wire 9 is made of aluminum wire. Aluminum has a soft texture and good flexibility and can withstand multiple bending. The surface of aluminum will be oxidized in the air to form an oxide film. The oxide film will be grayish, which is not obvious with the black color and cannot form a strong contrast. Therefore, when the display wire 9 is made, it is necessary to first grind and remove the oxide film, and then anodize and paint the outer surface of the aluminum wire, and spray the aluminum wire with white, yellow or other bright colors, so as to form a strong contrast with the black color. The curve of the display wire 9 is relative to the vertical cross-sectional shape of the small port 2, the single-peak dust cover 1 and the large port 3. After the single-wave dust cover 1, the small port 2 and the large port 3 are cast in the molding mold, when the single-wave dust cover 1, the small port 2 and the large port 3 are still in liquid state, a plurality of display wires 9 after spraying are inserted into the mold in a circular shape with equal intervals, and when the single-wave dust cover 1, the small port 2 and the large port 3 are in solid state, they can be taken out. The display wire 9 can also be made of copper wire. In order to enhance the sense of contrast, the outer wall of the copper wire still needs to be sprayed, so that when the outer wall of the single-wave dust cover 1, the small port 2 and the large port 3 is damaged and reaches the position of the display wire 9, the display wire 9 forms a strong contrast with the black color, which is conducive to the maintenance personnel to promptly discover the damage of the sheath and replace and maintain it in time.

[0023] Specifically, a plurality of reinforcing ribs 8 for enhancing the structural strength are arranged at the connection between the single-wave-peak dust cover 1 and the large port 3. The plurality of reinforcing ribs 8 are arranged at equal intervals in a ring shape along the connection between the single-wave-peak dust cover 1 and the large port 3. The outer walls of the small port 2 and the large port 3 are respectively fixedly connected with a first baffle 4 and a second baffle 5 for limiting the installation position of the clamp. The first sealing ring 6 is arranged in the middle of the inner wall of the small port 2, and the second sealing ring 7 is arranged in the middle of the inner wall of the large port 3. The wave peak cross-section of the small port 2 is U-shaped.

[0024] Furthermore, the reinforcing rib 8, the first baffle 4, the first sealing ring 6, the second sealing ring 7 and the first sealing ring 6 are made of the same material as the single-peak dust cover 1, and are all integrally formed during mold casting. The first baffle 4 and the second baffle 5 can respectively limit the movement of the clamps installed on the outer walls of the small port 2 and the large port 3 to ensure the accuracy of the clamp extrusion and tightening position. The positions of the first sealing ring 6 and the second sealing ring 7 are respectively located in the middle of the clamp installation position, so that when the clamp is gradually tightened, the first sealing ring 6 and the second sealing ring 7 will be continuously squeezed to ensure that a sealed space is formed inside the small port 2 to block dust and rainwater. The single-peak design of the single-peak dust cover 1 can reduce the overall volume of the sheath, reduce the space occupied by the sheath, and also reduce the manufacturing cost of the sheath.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
