For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0025] Reference example Figures 1 to 4 A wear-resistant device for a wire harness comprises a first protective sleeve 1 and a second protective sleeve 2. The first protective sleeve 1 is detachably connected and fixed to the second protective sleeve 2 to form a curved wire hole 3 through which the wire harness can be inserted. The inner walls of the wire hole 3 are respectively provided with a first inner pad 4 and a second inner pad 5. The inner wall of the first inner pad 4 is provided with a plurality of equally spaced convex humps 41, which abut against the surface of the wire harness to increase the friction with the wire harness; the inner wall of the second inner pad 5 is provided with a plurality of equally spaced elastic parts 51 extending in the axial direction of the second inner pad 5, and acting on the wire harness, so that the wire harness is closely attached to the first inner pad 4, so as to ensure the stable connection between the wire harness and the wire hole 3;

[0026] It is worth mentioning that fixing blocks 6 are provided at both ends of the first protective sleeve 1 and the second protective sleeve 2, and mounting holes 61 are provided at the upper and lower parts of the fixing blocks 6. A countersunk hole 62 is provided at one end of the mounting hole 61 and is close to the outer wall of the first protective sleeve 1 and the second protective sleeve 2. The fixing block 6 mainly plays the role of fitting the surface of the supporting object and providing a support point for the first protective sleeve 1 and the second protective sleeve 2. While the first protective sleeve 1 and the second protective sleeve 2 raise the wiring harness, they also prevent the wiring harness from rubbing against the side wall of the supporting object, thereby extending the service life of the wiring harness. The fastener passes through the mounting hole 61 to fix the first protective sleeve 1 and the second protective sleeve 2 on the supporting object, and the head of the fastener is set in the countersunk hole 62 to prevent the protruding part from interfering with other wiring.

[0027] It is worth mentioning that elastic arms 11 are provided at the upper and lower ends of the first protective sleeve 1, and the elastic arms 11 are provided with buckle blocks 12. The elastic arms 11 store energy so that the buckle blocks 12 are tightly attached to the extension blocks 21;

[0028] It is worth mentioning that the second protective sleeve 2 is provided with extension blocks 21 on both sides, and through holes 22 for the elastic arms 11 and the buckle blocks 12 to pass through are provided at the upper and lower sides of the extension blocks 21. The extension blocks 21 are used in conjunction with the through holes 22. When the elastic arms 11 and the buckle blocks 12 pass through the through holes 22, the buckle blocks 12 are buckled on the extension blocks 21, which not only plays a role in connecting and fixing the first protective sleeve 1 and the second protective sleeve 2, but also plays a role in limiting the left and right displacement of the second protective sleeve 2.

[0029] It is worth mentioning that the first inner pad 4 and the second inner pad 5 are arranged between the fixing block 6 and respectively fit the inner walls of the first protective sleeve 1 and the second protective sleeve 2. The first protective sleeve 1 and the second protective sleeve 2 respectively provide support points for the first inner pad 4 and the second inner pad 5.

[0030] It is worth mentioning that the detachable type is set as a buckle block 12, and is buckled on the extension block 21. The shapes of the first protective sleeve 1 and the second protective sleeve 2 are set to be curved, and the cross-sectional shapes of the first protective sleeve 1 and the second protective sleeve 2 are set to be semi-arc-shaped. The curved structure not only increases the bending angle of the wire harness, effectively reduces the metal fatigue of the wire harness, but also is closer to the curved part of the supporting object, and the semi-arc shape fits the outer wall of the wire harness more closely;

[0031] It is worth mentioning that the first protective sleeve 1 and the second protective sleeve 2 are made of soft material, and the first inner pad 4 and the second inner pad 5 are made of rubber material. The soft material can be polyurethane or polychloroprene rubber. Both materials have excellent softness, toughness and wear resistance, so that the first protective sleeve 1 and the second protective sleeve 2 can be bent into a bending angle that better fits the supporting object.

[0032] The use principle of the utility model is now described as follows:

[0033] Place the wiring harness on the first protective sleeve 1 so that the wiring harness abuts against the first inner pad 4, take the second protective sleeve 2, align the through hole 22 with the elastic arm 11, and then cover the first protective sleeve 1 and the second protective sleeve 2. After the elastic arm 11 is squeezed by the through hole 22 and shrinks toward the axial direction of the first protective sleeve 1, the buckle block 12 enters the through hole 22. When the buckle block 12 passes through the through hole 22, it is no longer subject to resistance, and the elastic arm 11 releases the elastic force, so that the buckle block 12 is buckled on the extension block 21, so that the first protective sleeve 1 is connected and fixed with the second protective sleeve 2;

[0034] The second inner pad 5 pushes the wire harness to bend, thereby matching the bending shape of the first inner pad 4, and allowing the elastic part 51 to store energy until the wire harness fits on the convex bulge 41 of the first inner pad 4. The elastic part 51 releases elastic force to act on the wire harness, so that the wire harness is pressed tightly against the convex bulge 41, thereby completing the connection between the wire harness and the first protective sleeve 1 and the second protective sleeve 2;

[0035] At this time, the first protective sleeve 1 and the second protective sleeve 2 are fixed to the supporting object by fasteners.

[0036] The above design scheme can enable the product to achieve the advantages of long service life and reliable clamping.

[0037] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
