Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a tear-resistant composite reinforced rubber sleeve. Background Technology

[0002] Automotive parts refer to the various units that make up a car and the products that serve the car. In a broad sense, they encompass all materials needed by automotive repair and manufacturing companies, including automotive parts, repair materials, and automotive supplies.

[0003] In automotive parts, automotive wiring harnesses are an important component of the automotive electrical network, responsible for connecting various electrical components and realizing power supply and signal transmission. To protect the wiring harness from external environmental corrosion and mechanical damage, it is usually wrapped with a rubber sheath. Existing technology (Chinese patent application CN202422369206.3, filed on 2024-09-27) discloses a rubber sheath for automotive wiring harnesses. During use, it includes a sheath body and a connecting mechanism. Positioning rings are fixedly connected to both ends of the sheath body, and snap-fit ​​components are provided on the positioning rings. The connecting mechanism includes... The device includes a fixing ring, with a tension spring fixedly connected to the inner wall of the fixing ring. A docking ring is fixedly connected to the end of the tension spring away from the fixing ring. The positioning ring is connected to the docking ring via a snap-fit ​​structure. In use, the connecting ring is connected to the wiring port of the vehicle body. When a lot of heat is generated at the connection point, the docking ring and the fixing ring are separated by pulling the sheath body, which facilitates the dissipation of the accumulated heat at the wiring harness terminal. The operation is simple and facilitates timely heat dissipation. After the heat dissipates, the tension spring is released, and the docking ring and the fixing ring are tightly fitted again, achieving rapid heat dissipation while maintaining a seal.

[0004] Although existing technologies can improve the ease of use of rubber sleeves, the structure of rubber sleeves is relatively simple during operation. They are usually made of a single type of rubber. Vibrations during vehicle operation and bending of the wiring harness can cause repeated stress on the sleeves, leading to tearing and affecting their service life. In addition, the fixing structure of rubber sleeves is relatively simple, and they may fall off in bumpy vehicle environments. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tear-resistant composite reinforced rubber sleeve, comprising a rubber sleeve body, wherein a first fixing ring is fixedly connected to the top end of the rubber sleeve body, and a second fixing ring is fixedly connected to the bottom end of the rubber sleeve body; a first mating ring is rotatably connected to the top surface of the first fixing ring, and a second mating ring is rotatably connected to the bottom surface of the second fixing ring.

[0010] Furthermore, the cylindrical skeleton is arranged longitudinally inside the rubber sleeve body, and the cylindrical skeletons are symmetrically distributed about the central axis of the rubber sleeve body, and the cylindrical skeleton is made of aramid fiber material.

[0011] Furthermore, the annular skeleton is arranged longitudinally inside the rubber sleeve body, and the annular skeleton is evenly distributed inside the rubber sleeve body, and the annular skeleton is made of aramid fiber material.

[0013] Furthermore, there are multiple fixing blocks, and the fixing blocks are symmetrically distributed about the central axis of the first fixing ring and the second fixing ring, and the fixing blocks are made of rubber.

[0014] Furthermore, each of the first and second fixing rings has a fixing bolt on one side, and the inner walls of the first and second fixing rings are provided with positioning holes whose internal dimensions are consistent with the external dimensions of the fixing bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the tear-resistant composite reinforced rubber sleeve adopts a novel structural design, the specific details of which are as follows:

[0016] (1) The tear-resistant composite reinforced rubber sleeve is provided with a rubber sleeve body and a skeleton assembly. Through the synergistic effect of the cylindrical skeleton and the ring skeleton made of aramid fiber, the longitudinally distributed cylindrical skeleton is circumferentially distributed to form a longitudinal stress transmission network. The longitudinally equidistant ring skeleton forms a constraint ring. The three-dimensional structure of warp and weft can effectively disperse the stress generated by the dynamic bending of the wire bundle, improve the tear resistance of the rubber sleeve body, and avoid tearing caused by stress concentration.

[0017] (2) The tear-resistant composite reinforced rubber sleeve is provided with a first fixing ring, a second fixing ring, a first mating ring and a second mating ring. The fixing blocks on the inner walls of the first fixing ring and the second fixing ring can limit the position of the automotive wiring harness.

At the same time, the rubber sleeve body can be extended as needed to effectively improve the installation efficiency. Attached Figure Description

[0026] Example 1: Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 This utility model provides the following technical solution: a tear-resistant composite reinforced rubber sleeve, disclosing a rubber sleeve body 1 and a skeleton assembly 11: including a reinforcing layer 10 inside the rubber sleeve body 1, and a skeleton assembly 11 inside the reinforcing layer 10, such as... Figure 6 As shown, the skeleton assembly 11 includes a cylindrical skeleton 1101 disposed inside the reinforcing layer 10, and an annular skeleton 1102 penetrating through the outer wall of the cylindrical skeleton 1101, as shown.

[0027] In use, by setting a reinforcing layer 10 and a skeleton component 11 inside the rubber sleeve body 1, the tear resistance of the rubber sleeve can be significantly improved. Through the synergistic effect of the cylindrical skeleton 1101 and the annular skeleton 1102 made of aramid fiber, the longitudinally distributed cylindrical skeleton 1101 is circumferentially symmetrically distributed to form a longitudinal stress transmission network, and the longitudinally equidistant annular skeleton 1102 forms a constraint ring.

The dimensions and structure of the external thread 8 are consistent with the dimensions and structure of the internal thread groove 9. Figure 3 As shown, a fixing block 6 is fixedly connected to the inner wall of the first fixing ring 2 and the second fixing ring 3. The fixing block 6 is circular in shape, and a notch is provided on one side of the fixing block 6. Figure 3 As shown, multiple fixing blocks 6 are provided, and the fixing blocks 6 are symmetrically distributed about the central axis of the first fixing ring 2 and the second fixing ring 3.

[0029] In use, the automotive wiring harness is passed through the middle of the rubber sleeve body 1, and then fixed by the fixing block 6 on the inner wall of the first fixing ring 2. Next, the automotive wiring harness is fixed again by the fixing block 6 on the inner wall of the second fixing ring 3. The rubber sleeve body 1 can be extended as needed. The ends of the rubber sleeve body 1 are connected, and the external thread 8 of the first mating ring 4 and the internal thread groove 9 of the second mating ring 5 are threaded together to quickly fix the rubber sleeve body 1. At this time, the positioning holes of the first fixing ring 2 and the first mating ring 4 are aligned, and the positioning holes of the second fixing ring 3 and the second mating ring 5 are aligned.
