Description

Technical Field

[0001] This utility model relates to the technical field of wire harness semi-finished product placement carts, and in particular to a wire harness semi-finished product placement cart. Background Technology

[0002] The wire harness semi-finished product placement cart is mainly used for the temporary storage, classification, and convenient transfer of wire harness semi-finished products in the workshop. It can avoid damage and confusion caused by random stacking of semi-finished products, and can flexibly shuttle between various workstations, reducing the intensity of manual handling, improving the efficiency and standardization of semi-finished product circulation in the wire harness production process, and helping the production process to proceed in an orderly manner.

[0003] In the wire harness production process in the automotive, electronics and other fields, the temporary storage and transfer of wire harness semi-finished products rely on placement trolleys with U-shaped brackets. The U-shaped brackets can provide initial support for the cables with their groove structure, and have become a common wire harness storage carrier in the workshop. However, in the existing technology, these U-shaped brackets generally do not have any pressure plate structure for fixing the wire harnesses. They only rely on the two side walls of the U-shaped groove for simple positioning. Due to the lack of pressure plate constraint, the stability is extremely poor when storing wire harness semi-finished products of different diameters. Wire harnesses with smaller diameters are easy to slip off from the opening of the U-shaped groove when the trolley moves, turns or experiences slight bumps, resulting in wire harness loss or surface wear. In response to the technical problem of difficulty in limiting the position of wire harnesses, this application proposes a wire harness semi-finished product placement trolley. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies in terms of difficulty in limiting the position of wire harnesses. It proposes a wire harness semi-finished product placement trolley. By setting a sliding pressure plate on the U-shaped frame, it can fill the gap of existing technologies that do not have pressure plates. It can adapt to wire harnesses of different diameters, prevent them from slipping, shaking or getting tangled, prevent terminal deformation and insulation layer damage, and eliminate the need for additional binding straps, reducing operation steps.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A wire harness semi-finished product placement trolley includes a base, with multiple connecting frames slidably connected to the inner wall of the base. Each connecting frame has multiple knobs rotatably connected to its inner wall, and each knob has a movable component at its bottom end for fixing the wire harness. Each connecting frame has multiple U-shaped frames fixedly connected to its inner wall. A crank handle is rotatably connected to the inner wall of the base, and the left end of the crank handle is connected to the connecting frame via a snap-fit ​​component for adjusting the height of the connecting frame.

[0006] Furthermore, the movable component includes a pressure plate slidably connected to the outer wall of the U-shaped frame, a rotating rod rotatably connected to the inner wall of the pressure plate, a slider rotatably connected to the other end of each rotating rod, and the outer wall of each slider slidably connected to the inner wall of the connecting frame.

[0007] Furthermore, each of the inner walls of the connecting frame is rotatably connected to a threaded rod, and the outer walls of the threaded rods are threadedly connected to the inner wall of the slider.

[0008] Furthermore, each knob has a main bevel gear fixedly connected to its bottom end, and each main bevel gear has a secondary bevel gear meshing with its outer wall. The outer wall of each secondary bevel gear is fixedly connected to the inward end of the threaded rod.

[0009] Furthermore, the buckle assembly includes a card plate that is slidably connected to the inner wall of the base, and the connecting frame has card slots at both the front and rear ends, with the shape of the card plate matching the card slots.

[0010] Furthermore, sliding frames are slidably connected to both sides of the inner wall of the base, and transmission rods are rotatably connected to both sides of the inner wall of the sliding frames, with the other end of each transmission rod rotatably connected to the inner wall of the card plate.

[0011] Furthermore, a bidirectional screw is fixedly connected to the left end of the crank handle, and both sides of the outer wall of the bidirectional screw are threaded to the inner wall of the sliding frame, and the outer wall of the bidirectional screw is rotatably connected to the inner wall of the base.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by setting a sliding pressure plate on the U-shaped frame, the gap of the prior art without a pressure plate can be filled. It can be adapted to wire harnesses of different diameters, preventing them from slipping, shaking or getting tangled, preventing terminal deformation and insulation layer damage, and eliminating the need for additional binding straps, thus reducing operation steps.

[0013] 2. In this utility model, by adjusting the height of the connecting frame and the U-shaped frame, wire harnesses of different lengths can be adapted as needed, avoiding the long wire harnesses from drooping and swinging at both ends due to lack of adaptation support, reducing friction and wear with the ground or components, preventing entanglement and hooking with adjacent wire harnesses, and saving sorting and combing time.

[0016] 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.

[0017] Reference Figures 2-4 As shown, one embodiment of this utility model provides a wire harness semi-finished product placement trolley, including a base 1. Multiple connecting frames 2 are slidably connected to the inner wall of the base 1. Multiple knobs 3 are rotatably connected to the inner wall of each connecting frame 2. Pressure plates 9 are slidably connected to the outer wall of each U-shaped frame 10. Rotating rods 8 are rotatably connected to the inner wall of each pressure plate 9. A slider 7 is rotatably connected to the other end of each rotating rod 8. The outer wall of each slider 7 is slidably connected to the inner wall of each connecting frame 2. Threaded rods 6 are rotatably connected to the inner wall of each connecting frame 2. The outer wall of each threaded rod 6 is threadedly connected to the inner wall of each slider 7. A main bevel gear 4 is fixedly connected to the bottom end of each knob 3. A secondary bevel gear 5 is meshed with the outer wall of each main bevel gear 4. The outer wall of each secondary bevel gear 5 is fixedly connected to the inward end of each threaded rod 6 for fixing the wire harness.

[0018] Specifically, the pressure plate 9 is made of rubber to avoid damaging the wire harness. By setting a pressure plate 9 that can slide up and down on the U-shaped frame 10, it can fill the gap of the existing technology that does not have a pressure plate 9. It can be adapted to wire harnesses of different diameters, prevent them from slipping, shaking or getting tangled, prevent terminal deformation and insulation layer damage, and eliminate the need for additional binding ties, reducing operation steps.

[0019] Reference Figure 1 , Figure 5 and Figure 6As shown, multiple U-shaped frames 10 are fixedly connected to the inner wall of the connecting frame 2. A crank 12 is rotatably connected to the inner wall of the base 1. A card plate 16 is slidably connected to the inner wall of the base 1. Card slots 11 are provided at both the front and rear ends of the connecting frame 2. The shape of the card plate 16 fits the card slot 11. Sliding frames 14 are slidably connected to both sides of the inner wall of the base 1. Transmission rods 15 are rotatably connected to both sides of the inner wall of the sliding frame 14. The other end of the transmission rod 15 is rotatably connected to the inner wall of the card plate 16. A double-acting screw 13 is fixedly connected to the left end of the crank 12. The outer walls of the double-acting screw 13 are threaded to the inner wall of the sliding frame 14 on both sides. The outer walls of the double-acting screw 13 are rotatably connected to the inner wall of the base 1 for adjusting the height of the connecting frame 2.

[0020] Specifically, by adjusting the height of the connecting frame 2 and the U-shaped frame 10, different lengths of wire harnesses can be adapted as needed, preventing long wire harnesses from drooping and swinging at both ends due to lack of adaptation support, reducing friction and wear with the ground or components, preventing tangling and hooking with adjacent wire harnesses, and saving sorting and combing time.

[0021] Working principle: First, when placing the wire harness, simply pass the wire harness through the U-shaped frame 10, hang the wire harness on the U-shaped frame 10, and rotate the corresponding knob 3. The knob 3 drives the main bevel gear 4 to rotate, the main bevel gear 4 drives the secondary bevel gear 5 to rotate, the secondary bevel gear 5 drives the threaded rod 6 to rotate, the threaded rod 6 drives the slider 7 on the outer wall to slide to the middle side, and drives the rotating rod 8 to rotate, pulling the pressure plate 9 to slide downwards, limiting the wire harness. When it is necessary to remove the wire harness, the knob 3 can be rotated in the opposite direction to release the limitation on the pressure plate 9 and remove the wire harness. When placing wire harnesses of different lengths, first turn the crank handle 12. The crank handle 12 drives the bidirectional screw 13 to rotate, which in turn drives the sliding frames 14 on both sides of the outer wall to slide outwards. This drives the transmission rod 15 to rotate and pushes the clamping plates 16 on both sides to slide outwards. Remove the clamping plates 16 from the clamping slots 11 to release the restriction on the connecting frame 2. Then, the connecting frame 2 can be slid up and down to adjust its height. After the adjustment is completed, turn the crank handle 12 in the opposite direction to insert the clamping plates 16 on both sides into the clamping slots 11. This will limit the connecting frame 2 and complete the adjustment.

[0022] 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.
