[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figures 1-2 As shown, this application provides an automotive wiring harness protection device, including a main cylinder 2, which is mainly composed of a lower cylinder 21 and an upper cylinder 22. Both the upper cylinder 22 and the lower cylinder 21 are semi-circular. When they are combined, they form a circular cylinder. The automotive wiring harness passes through the main cylinder 2 and is protected by the upper cylinder 22 and the lower cylinder 21.

[0028] Side cylinders 1 are fixedly installed on both sides of the lower cylinder 21. The side cylinders 1 are also circular cylinders with the same inner diameter as the main cylinder 2. Slide rods 12 are fixedly installed on both sides inside the side cylinders 1. Slide rings 11 are slidably installed on the slide rods 12. The inner diameter of the slide rings 11 is the same as the inner diameter of the side cylinders 1. Industrial tape 14 is fixedly installed on the inner wall of the slide rings 11. The industrial tape 14 is mainly used to bind and fix the two ends of the automotive wiring harness.

[0029] During vehicle operation, varying road conditions inevitably cause strain on the vehicle's wiring harness. When this strain occurs, the industrial tape 14 used to secure it shifts, causing the sliding ring 11 to move. The sliding ring 11 slides on the slide rod 12, adapting to the strain on the wiring harness. This allows the wiring harness to remain fixed while adapting to short-distance strain. Furthermore, once the road conditions stabilize, the wiring harness needs to be reset. Figure 2As shown, the reset spring 13 is sleeved on the surface of the slide rod 12, and the two ends of the reset spring 13 are fixedly connected with the sliding ring 11 and the inner wall of the side cylinder 1 respectively, so that when the sliding ring 11 slides, the reset spring 13 will be extruded, and when the sliding ring 11 is not subjected to external force, the reset spring 13 will drive the sliding ring 11 to return to the initial position, so that the automobile wire harness can be kept in the initial state.

[0030] As shown in Figures 1-6 The connecting assembly 3 is arranged between the upper cylinder body 22 and the lower cylinder body 21, and mainly realizes quick installation and disassembly through the connecting assembly 3. For the convenience of description, mounting platforms are arranged on both sides of the upper cylinder body 22 and the lower cylinder body 21, wherein the mounting platform on the lower cylinder body 21 is defined as a first platform 211, and the mounting platform on the upper cylinder body 22 is defined as a second platform 221. The connecting assembly 3 includes a connecting plate 31, a plurality of positioning pins 32 are fixedly installed on the bottom of the connecting plate 31, and positioning holes matched with the positioning pins 32 are formed in the first platform 211 and the second platform 221. During installation, the positioning pins 32 are inserted into the positioning holes.

[0031] Mounting grooves 33 are formed in the surfaces of the first platform 211 and the second platform 221, and a limiting block 34 is fixedly installed on the bottom of the connecting plate 31. The limiting block 34 is suitable for being inserted into the mounting groove 33. After the positioning pin 32 is inserted into the positioning hole and the limiting block 34 is inserted into the mounting groove 33, the connecting plate 31 cannot rotate but can only move up and down.

[0032] A rotating block 35 is installed at the bottom of the limiting block 34. A rotating shaft (not marked in the figure) is rotatably installed at the center of the rotating block 35. One end of the rotating shaft is fixedly connected with the limiting block 34, and the other end of the rotating shaft protrudes from the rotating block 35. A handle 36 is movably installed on the surface of the rotating shaft. The handle 36 is fixedly installed with the rotating block 35, so that the rotating block 35 can be rotated by rotating the handle 36 with the help of a tool or manually.

[0033] It should be noted that in the initial state, the setting direction of the rotating block 35 is consistent with that of the limiting block 34, which can be referred to Figure 7 The outer diameter of the handle 36 and the width of the rotating block 35 are both smaller than the width of the mounting groove 33, so that the handle 36 and the rotating block 35 can pass through the mounting groove 33 to reach the back of the first platform 211.

[0034] Continuing to refer to Figures 3-7A first fixing member 37 and a second fixing member 371 are fixedly installed on both sides of the back of the first platform 211. The first fixing member 37 and the second fixing member 371 are both composed of a fixing rod fixedly installed at the bottom of the first platform 211 and a plate fixedly installed at the other end of the fixing rod. An arc-shaped box 310 is fixedly installed on the plate. It should be noted that the first fixing member 37 and the second fixing member 371 are located on both sides of the mounting groove 33, so that the arc-shaped box 310 can be easily fixed to ensure its stability.

[0035] like Figures 3-7 As shown, an upper stop block 39 is fixedly installed on one side of the back of the first platform 211, and a limit cylinder 38 is fixedly installed on the other side of the back of the first platform 211. A limit spring 312 is fixedly installed inside the limit cylinder 38, and a limit plate 311 is fixedly installed on the top of the limit spring 312. A limit stop block (not shown in the figure) is fixedly installed on the side of the limit plate 311 facing the back of the first platform 211. The limit stop block passes through the arc-shaped box 310 and abuts against the back of the first platform 211. It can be understood that the arc-shaped box 310 is provided with a through groove that matches the limit stop block. The through groove is used to lock the position of the limit stop block to prevent the limit stop block from rotating or translating. At this time, the limit stop block can only be adjusted by the worker using tools or by manually pulling the limit plate 311.

[0036] In the initial state, you can refer to Figure 7 At this time, the rotating block 35 is in a horizontal position, and the limiting block is in contact with the back of the first platform 211. At this time, the two sides of the rotating block 35 are not in contact with the upper block 39 and the limiting block. When the operator needs to connect the upper cylinder 22 and the lower cylinder 21, the operator must first place the upper cylinder 22 on the lower cylinder 21 and align the first platform 211 with the second platform 221. Then, the connecting plate 31 is placed on top of the second platform 221, the positioning pin 32 is aligned with the positioning hole, the limiting block 34 is inserted into the mounting groove 33, and the connecting assembly 3 is in position. Figure 7 The state in;

[0037] During installation, the operator first manually or with tools pulls the limiting plate 311 away from the first platform 211. The limiting spring 312 is stretched, and the top of the limiting block separates from the first platform 211, creating a gap between the limiting block and the first platform 211. Then, the operator rotates the handle 36, causing the rotating block 35 to rotate synchronously, allowing it to pass through the gap and ultimately turn into a vertical position (see reference). Figure 7), at this time one side of one end of the rotating block 35 is in contact with the upper stop block 39, then the worker releases the pulling of the limiting plate 311, under the action of the limiting spring 312, the limiting stop block returns to the initial position, the other end of the rotating block 35 is in contact with the limiting stop block;

[0038] Since the upper stop block 39 is in a fixed state, and the limiting stop block can only move up and down and cannot be translated, at this time the rotating block 35 cannot move up and down and cannot be rotated, for this reason the connecting plate 31 is fixed at this time and cannot be rotated and cannot move up and down, the upper barrel 22 and the lower barrel 21 are in a fixed state, then the worker passes the automobile wire harness in the main barrel 2, and the two ends of the automobile wire harness are bundled by the industrial adhesive tape 14, thereby realizing the fixation and protection of the automobile wire harness;

[0039] When it is necessary to overhaul the automobile wire harness, the worker only needs to pull down the limiting plate 311, then rotates the rotating handle 36, rotates the rotating block 35 from the vertical state to the horizontal state, then releases the limiting plate 311, can take out the connecting plate 31 from the installation slot 33, realizes the separation and disassembly of the upper barrel 22 and the lower barrel 21, can overhaul the automobile wire harness in the main barrel 2.

[0040] The above only describes the preferred embodiments of the present application and is not used to limit the present application, for those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
