Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3An exposed wire protection device for electrical engineering includes an upper housing 1 and a lower housing 2. Both the upper housing 1 and the lower housing 2 are U-shaped. The lower end of the upper housing 1 is fixedly connected with four first threaded rods 3. The bottom of the lower housing 2 is horizontally provided with a rectangular through groove. The upper end of the lower housing 2 is vertically provided with four first cylindrical through grooves 4. The lower end of the lower housing 2 is provided with four threaded sleeves 12. Each threaded sleeve 12 is threadedly connected to the lower end of the corresponding first threaded rod 3.

[0020] The system also includes a positioning component, which includes a rectangular slider 5 disposed in a rectangular through groove. The rectangular slider 5 is slidably connected to the inner wall of the rectangular through groove. A positioning block 6 is fixedly connected to the upper end of the rectangular slider 5. The upper end of the positioning block 6 is provided with multiple arc-shaped positioning grooves 7. The multiple arc-shaped positioning grooves 7 can completely fit with the outer side of the corresponding exposed wire to facilitate subsequent safe limiting (i.e., the wire will not be excessively squeezed during limiting). The upper end of the rectangular slider 5 is vertically provided with four second cylindrical through grooves 8. The four first threaded rods 3 are slidably connected to the corresponding first cylindrical through grooves 4 and the corresponding second cylindrical through grooves 8.

[0021] The device also includes a limiting component, which is used to limit the exposed wire. The limiting component includes a pressure plate 9 set at the top inside the upper housing 1. The pressure plate 9 fits against the inner wall of the upper housing 1. The upper end of the upper housing 1 has a threaded opening. A second threaded rod 10 is threaded through the threaded opening and is threaded to the threaded opening. The lower end of the second threaded rod 10 is rotatably connected to the upper end of the pressure plate 9. A rubber pad 11 is provided at the lower end of the pressure plate 9. The rubber pad 11 can improve the limiting effect of the pressure plate 9 on the exposed wire and can avoid excessive compression of the exposed wire.

[0022] In this invention, the initial state of the entire device is as follows: Figure 2 As shown, during use, the exposed wires to be protected are sorted and placed into the multiple arc-shaped positioning grooves 7 on the upper end of the positioning block 6. Then, the four first threaded rods 3 at the lower end of the upper housing 1 are aligned with the corresponding first cylindrical through grooves 4 and inserted. During this process, the four first threaded rods 3 will pass through the corresponding second cylindrical through grooves 8 to limit the rectangular slider 5 and the positioning block 6. When the lower end of the upper housing 1 is in contact with the upper end of the lower housing 2, the threaded parts of the lower ends of the four first threaded rods 3 will be exposed below the lower housing 2. At this time, the four threaded sleeves 12 are threadedly connected to the threaded parts of the corresponding first threaded rods 3 to realize the assembly of the entire device. After the assembly is completed, the second threaded rod 10 is rotated to drive the pressure plate 9 and the rubber pad 11 to move down synchronously. In this way, the stable clamping and limiting of the exposed wires can be achieved. The assembly of the entire protection device and the subsequent limiting of the wires are relatively convenient, avoiding the wires from being exposed to the outside and damaged. Moreover, the multiple arc-shaped positioning grooves 7 can realize the classification and fixing of the wires, ensuring the safe use of the line.

[0023] It is worth mentioning that when it is necessary to fix and protect wires of different sizes and specifications, firstly, separate the upper shell 1 and the lower shell 2 so that the four first threaded rods 3 disengage from the corresponding second cylindrical through slots 8, thereby removing the limit on the rectangular slider 5. At this time, the rectangular slider 5 and the positioning block 6 can be moved forward and taken out. Then, the rectangular slider 5 and the positioning block 6 that meet the wire size requirements (the multiple arc-shaped positioning grooves 7 at the upper end of the positioning block 6 can fit against the outside of the wire to be protected to ensure the stable fixation of the wire in the future) are inserted into the rectangular through slot. Finally, the four first threaded rods 3 are controlled to position the rectangular slider 5. In this way, the fixing and protection of wires of different sizes and specifications can be achieved, and the overall adaptability is good.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
