Description

Technical Field

[0001] The utility model relates to the technical field of automotive wiring harnesses, in particular to an automotive wiring harness that prevents loosening. Background Technique

[0002] The automotive wiring harness is the main body of the automotive circuit network. Without the wiring harness, there would be no automotive circuit. A wiring harness refers to a component formed by crimping contact terminals made of copper material onto a wire and cable, and then molding an insulator or adding a metal housing outside, etc., and bundling the wiring harness to form a component for connecting the circuit;

[0003] For example, patent number 202323062057.8 discloses an automotive wiring harness fixing structure, including a bellows hose. Installation plates are fixedly installed on both sides of the bellows hose. First boxes are fixedly installed on the sides of the two installation plates away from each other. Connecting blocks are fixedly installed on both sides of the two first boxes. A rotating rod is arranged between adjacent connecting blocks. The rotating rod is inserted into the connecting block and rotatably connected thereto. An auxiliary structure is arranged on the outer sides of the two rotating rods. The auxiliary structure includes a second box. The second box is fixedly connected to the rotating rod. Two installation slots are opened on each of the two first boxes and the second box. Two threaded rods are arranged on the top of the second box. The two threaded rods penetrate through the second box and are threadedly connected thereto. Rotating plates are fixedly installed at the bottoms of the two threaded rods. Pressure plates are arranged below the second box at the bottoms of the two threaded rods. The threaded rods are inserted into the pressure plates and rotatably connected thereto. The rotating plates are rotatably connected to the pressure plates. In the utility model, the wiring harness is passed through the installation slots opened on the first box and the second box. According to the diameter of the wiring harness, the pressure plate is longitudinally moved by manually rotating the threaded rod and is in contact with the wiring harness to fix the wiring harness. The position of the pressure plate during movement is restricted by the arranged guide rod, so as to separately fix the wiring harness and prevent the wiring harnesses from piling up and affecting the heat dissipation effect of the wiring harness. However, during the use by the staff of the automotive wiring harness clip, the position of the automotive wiring harness positioning mechanism is fixed, which is not convenient for the staff to adjust the spacing of the automotive wiring harness according to needs. Two automotive wiring harnesses with strong transmission efficiency are likely to affect each other, resulting in a reduction in the transmission efficiency of the automotive wiring harness. Moreover, the automotive wiring harness positioning mechanism generally can only fix wiring harnesses of one diameter, and has limitations in use;

[0004] Therefore, during the use of the above-mentioned automotive wire harness clamp by the staff, the position of the automotive wire harness positioning mechanism is fixed, which is not convenient for the staff to adjust the spacing of the automotive wire harness according to needs. Two automotive wire harnesses with strong transmission efficiency are likely to affect each other, resulting in a reduction in the transmission efficiency of the automotive wire harness. Moreover, the automotive wire harness positioning mechanism generally can only fix wire harnesses of one diameter, with limited use. To address these problems, a non-loose automotive wire harness can be designed. After passing the automotive wire harness through the guide seat, it is squeezed and fixed to the automotive wire harness by the squeezing seat at the top of the guide seat to prevent the automotive wire harness from loosening. Then, by rotating the knob, the lead screw rotates simultaneously while the knob rotates. The lead screw meshes with the two displacement blocks, so that the two displacement blocks move relative to each other inside the displacement groove during the rotation of the lead screw, facilitating the staff to adjust the spacing between the two displacement blocks and the automotive wire harness according to needs. Summary of the Invention

One end of the lead screw penetrates through the two displacement blocks and extends to the inner wall at the other end of the displacement groove.

[0009] As a preference, the lead screw is a double-headed threaded lead screw. The threads at both ends of the lead screw are symmetric with respect to the knob. The two displacement blocks mesh with the lead screw.

[0010] Preferably, a transmission rod is provided inside the connection base at one end of the knob. The top end of the transmission rod penetrates through the connection base and the displacement groove and extends to the bottom end of the lead screw. Bevel gears are provided at the intersection of the transmission rod and the lead screw, and the transmission rod and the lead screw are drivingly connected through the bevel gears.

[0011] Preferably, the extrusion seat and the extrusion block are of an integral structure. Guide grooves are provided on both sides of the extrusion seat inside the guide seat.

[0012] Preferably, connection seats are provided on both sides of the connection base, and bolt holes are provided at the central positions of the connection seats.

[0013] Advantages of the utility model:

[0014] After passing the automotive wiring harness through the guide seat, the extrusion seat at the top end of the guide seat is used to squeeze and fix the automotive wiring harness to prevent the automotive wiring harness from becoming loose. Then, by rotating the knob, the lead screw rotates simultaneously while the knob is rotating. The lead screw meshes with the two displacement blocks, so that the two displacement blocks move relative to each other inside the displacement groove during the rotation of the lead screw, facilitating the staff to adjust the distance between the two displacement blocks and the automotive wiring harness as needed.
