Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to an anti-wear elevator wiring harness. Background Technology

[0002] An elevator wiring harness is a collection of cables used to transmit power and signals in an elevator system. It consists of multiple conductors arranged in a specific pattern and wrapped with insulating material to ensure the safe transmission of power and signals. Elevator wiring harnesses typically include power lines, control lines, signal lines, and communication lines, responsible for connecting various parts of the elevator.

[0003] However, even after the existing elevator wiring harness is clamped, continuing to tighten the threaded post can still move the clamp towards the wiring harness, causing pressure or damage to the harness, resulting in damage to the wires and the harness insulation, increasing the risk of short circuits and electrical faults. Furthermore, excessive compression of the wiring harness will shorten its lifespan and increase maintenance and replacement costs.

[0004] Therefore, those skilled in the art have provided an anti-wear elevator wiring harness to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wear-resistant elevator wiring harness that can lock the position of the clamped wiring harness.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A wear-resistant elevator wiring harness includes a base plate and a wiring harness body. Vertical plates are fixedly installed on both sides of the upper end of the base plate. A threaded post is threaded between two of the vertical plates. A fixed plate is rotatably installed on the outer end of the threaded post near one of the vertical plates. A movable plate is threaded on the outer end of the threaded post near the other vertical plate. Multiple internal threaded blocks are threaded on the outer end of the threaded post. A No. 1 spring is installed on each of the four corners of the multiple internal threaded blocks. A limit mechanism is fixedly installed at the front end of the multiple movable plates.

[0008] Furthermore, the fixing plate is fixedly mounted on the upper end of the base plate, and the plurality of internal thread blocks are connected by a No. 1 spring. The fixing plate and the movable plate are connected to the internal thread blocks by a No. 1 spring.

[0009] Furthermore, the wire harness body includes a wear-resistant layer, and a protective layer is provided at the inner end of the wear-resistant layer.

[0010] Furthermore, the wear-resistant layer is made of polyurethane, and the protective layer is made of polyvinyl chloride.

[0011] Furthermore, the limiting mechanism includes a rotating block, a second spring is provided at the front end of the rotating block, a limiting plate is fixedly provided at the front end of the second spring, a fixing block is fixedly provided at the middle position of the rear end of the limiting plate, and two mounting slots are opened at both ends on the rear side of the limiting plate. A third spring is provided on one side of the two mounting slots, and a movable block is fixedly provided at the other end of the two third springs.

[0012] Furthermore, the rotating block is rotatably disposed at one of the front ends of the movable plate, and the fixed block is fixedly disposed between the two movable blocks.

[0013] Furthermore, one of the two vertical plates is disposed between one of the two movable blocks and the fixed block, and the limiting plate is movably disposed at the front end of one of the two vertical plates.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes an anti-wear elevator wiring harness. After the threaded post is turned, the movable plate and the internal threaded block will start to move, and then the wiring harness body will be placed into the hole between the movable plate, the internal threaded block and the fixed plate, thereby achieving the clamping of wiring harnesses of different specifications. The outermost wear-resistant layer of the wiring harness body is made of polyurethane. Polyurethane has excellent wear resistance and can effectively resist damage caused by friction. The protective layer at the inner end of the wear-resistant layer is made of polyvinyl chloride. Since polyvinyl chloride is a good insulating material, it can protect the wires in the wiring harness from external electrical interference.

[0016] 2. The wear-resistant elevator wiring harness proposed in this utility model, when the limiting mechanism is locked onto one of the vertical plates, first rotates the rotating block toward the vertical plate, and then pulls the movable block. Since a No. 3 spring is provided between the movable block and the fixed block, the movable block can move, thereby clamping the vertical plate with the fixed block. This can prevent the displacement of the movable plate and the internal threaded block after the threaded column is turned again, ensuring that the position remains unchanged during use, thereby improving safety.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 One embodiment provided by this utility model:

[0027] A wear-resistant elevator wiring harness includes a base plate 1 and a wiring harness body 9. Vertical plates 2 are fixedly installed on both sides of the upper end of the base plate 1. Threaded posts 3 are threaded between the two vertical plates 2. A fixed plate 4 is rotatably installed on the outer end of the threaded post 3 near one of the vertical plates 2. A movable plate 8 is threaded on the outer end of the threaded post 3 near the other vertical plate 2. Multiple internal threaded blocks 5 are threaded on the outer end of the threaded post 3. A first spring 6 is installed on each of the four corners of the multiple internal threaded blocks 5. A limit mechanism 7 is fixedly installed at the front end of the multiple movable plates 8. The fixed plate 4 is fixedly installed on the upper end of the base plate 1. The multiple internal threaded blocks 5 are connected by the first spring 6. The fixed plate 4 and the movable plate 8 are connected to the internal threaded blocks 5 by the first spring 6. The wiring harness body 9 includes a wear-resistant layer 10. A protective layer 11 is installed at the inner end of the wear-resistant layer 10. The wear-resistant layer 10 is made of polyurethane, and the protective layer 11 is made of polyvinyl chloride.

[0028] Specifically, after the threaded post 3 is turned, the movable plate 8 and the internal threaded block 5 will begin to move, and then the wire harness body 9 will be placed into the hole between the movable plate 8, the internal threaded block 5, and the fixed plate 4, thereby clamping wire harnesses of different specifications. The wear-resistant layer 10 at the outermost end of the wire harness body 9 is made of polyurethane. Polyurethane has excellent wear resistance and can effectively resist damage caused by friction. The protective layer 11 at the inner end of the wear-resistant layer 10 is made of polyvinyl chloride. Since polyvinyl chloride is a good insulating material, it can protect the wires in the wire harness from external electrical interference.

[0029] Reference Figure 5 , Figure 6 The limiting mechanism 7 includes a rotating block 701, a second spring 702 is provided at the front end of the rotating block 701, a limiting plate 703 is fixedly provided at the front end of the second spring 702, a fixing block 707 is fixedly provided at the middle position of the rear end of the limiting plate 703, two mounting slots 704 are opened at both ends on the rear side of the limiting plate 703, a third spring 705 is provided on one side of the two mounting slots 704, and a movable block 706 is fixedly provided at the other end of the two third springs 705.

[0030] The rotating block 701 is rotatably disposed at one of the front ends of the movable plate 8, and the fixed block 707 is fixedly disposed between the two movable blocks 706;

[0031] One of the two vertical plates 2 is positioned between one of the two movable blocks 706 and the fixed block 707, and the limiting plate 703 is movably positioned at the front end of one of the two vertical plates 2.

[0032] Specifically, when the limiting mechanism 7 is locked onto one of the vertical plates 2, the rotating block 701 is first rotated toward the vertical plate 2, and then the movable block 706 is pulled. Since a No. 3 spring 705 is provided between the movable block 706 and the fixed block 707, the movable block 706 can move, thereby clamping the vertical plate 2 with the fixed block 707. This can prevent the movable plate 8 and the internal threaded block 5 from shifting after the threaded column 3 is turned again, ensuring that the position remains unchanged during use, thereby improving safety.

[0033] Working principle: After the threaded post 3 is turned, the movable plate 8 and the internal threaded block 5 will start to move, and then the wire harness body 9 will be placed into the hole between the movable plate 8, the internal threaded block 5, and the fixed plate 4, thereby clamping wire harnesses of different specifications. The wear-resistant layer 10 at the outermost end of the wire harness body 9 is made of polyurethane. Polyurethane has excellent wear resistance and can effectively resist damage caused by friction. The protective layer 11 at the inner end of the wear-resistant layer 10 is made of polyvinyl chloride. Since polyvinyl chloride is a good insulating material, it can protect the wires in the wire harness from external electrical interference.

[0034] Secondly, when the limiting mechanism 7 is locked onto one of the vertical plates 2, the rotating block 701 is first rotated toward the vertical plate 2, and then the movable block 706 is pulled. Since the movable block 706 and the fixed block 707 are provided with a No. 3 spring 705, the movable block 706 can move, thereby clamping the vertical plate 2 with the fixed block 707, which can prevent the displacement of the movable plate 8 and the internal thread block 5 after the threaded column 3 is turned again.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
