Description

Technical Field

[0001] This utility model relates to the field of cable fixing technology for power distribution cabinets, and in particular to a cable fixing device for power distribution cabinets. Background Technology

[0002] Distribution cabinet cables are power cables that connect the distribution cabinet to the power source, electrical equipment, or other power distribution devices. They are used to transmit and distribute electrical energy, connect circuits, and ensure safety. The selection of cables should be based on voltage, current, environment, and other factors.

[0003] According to the announcement number CN213520720U, a cable fixing device for a distribution cabinet includes a base. Four first rods are symmetrically welded to the four corners of the upper surface of the base, and a first housing is welded to the top of each of the four first rods. Cables are inserted into the interior of a second housing through a first through slot, facilitating the connection of cables to electrical components installed inside the first housing via a fourth through slot. This significantly increases the effectiveness of the device in fixing cables and improves its working efficiency. However, the aforementioned document lacks a winding structure, preventing the winding of excess cable. This inevitably leads to cable tangling, compression causing damage to the cable insulation, and tangled cables, increasing the time maintenance personnel spend sorting through the lines and reducing maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of unwound cable wires when connecting cables to distribution cabinets in the prior art, and to propose a cable fixing device for distribution cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable fixing device for a power distribution cabinet includes a fixing plate disposed on the side wall of the power distribution cabinet. The fixing plate has a connecting fixing hole, a first limiting hole, and a second limiting hole. A pressure plate for clamping the cable is disposed in the fixing hole through a movable component. A rotating shaft is rotatably mounted on the fixing plate, and a turntable and a winding roller for winding the cable are fixedly mounted on the rotating shaft. The winding roller has a positioning hole for positioning the cable. The fixing plate is provided with a clamping structure for clamping the turntable.

[0007] Preferably, the fixing plate is threaded with a fixing bolt that connects to the power distribution cabinet, and a support pad for supporting the cable is glued into the fixing hole.

[0008] Preferably, the movable component includes a positioning post slidably sleeved in the second limiting hole, a pressure plate disposed on the positioning post, a spring welded between the pressure plate and the fixing plate, the positioning post and the pressure plate extending to the lower end position in the fixing hole, the pressure plate having an arc-shaped structure adapted to the cable, and the spring being sleeved on the positioning post.

[0009] Preferably, the take-up roller is provided with a rubber plug extending into the positioning hole and clamping both ends of the cable. The take-up roller is fixedly installed with symmetrically arranged limiting plates, and a protective shell for applying pressure to the cable is sleeved on the limiting plates. The inner wall of the protective shell is embedded with a rubber pad.

[0010] Preferably, the clamp structure includes a limiting frame fixedly installed on the fixed plate, and a limiting rod extending into the turntable is slidably sleeved inside the limiting frame, and a spring is welded between the limiting rod and the limiting frame.

[0011] Preferably, the limiting frame has an L-shaped structure, and the limiting frame has a limiting groove for guiding the limiting rod. The second spring is horizontally welded to one side of the limiting rod extending into the limiting frame. The turntable has three circumferentially distributed limiting holes that cooperate with the limiting rod. The limiting rod is integrally connected with a lever.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model provides a cable winding roller outside the cable fixing port, which can wind up the excess cable after it is connected to the distribution cabinet, effectively avoiding safety hazards caused by messy cables. During maintenance, the staff can quickly locate the problem. By installing rubber plugs in the positioning holes of the winding roller, the cable can be clamped and protected.

[0014] 2. This utility model uses an arc-shaped pressure plate to ensure that the outer surface of the cable is tightly fitted to the pressure plate, which can limit the lateral sliding and shaking of the cable. The arc-shaped structure can evenly distribute the clamping force on the cable, avoiding local compression of the cable and damage to the insulation layer. By setting a protective shell on the winding roller, the cable can be effectively prevented from being exposed to the sun and the surface insulation layer can be prevented from oxidizing. The rubber pad embedded in the protective shell can prevent the protective shell from contacting the cable and causing damage. Attached Figure Description

[0020] 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.

[0021] Reference Figures 1-4 A cable fixing device for a power distribution cabinet includes a fixing plate 1 disposed on the side wall of the power distribution cabinet. The fixing plate 1 is threaded with a fixing bolt 2 connected to the power distribution cabinet. The number of fixing plates 1 is the same as the number of cables connected to the power distribution cabinet, and the position of the fixing plate 1 is limited according to the different cable access positions of the power distribution cabinet.

[0022] The fixing plate 1 has a connected fixing hole 3, a limiting hole 1 5, and a limiting hole 2 6. A pressure plate 8 for clamping the cable is installed in the fixing hole 3 through a moving part. A support pad 4 for supporting the cable is glued in the fixing hole 3. The support pad 4 is preferably made of rubber. The rubber layer has good wear resistance and insulation properties, which can make the cable more evenly stressed and protect the insulation layer on the surface of the cable.

[0023] The movable component includes a positioning post 9 that is slidably sleeved in the limiting hole 2 6, a pressure plate 8 that is disposed on the positioning post 9, a spring 1 7 that is welded between the pressure plate 8 and the fixing plate 1, the positioning post 9 and the pressure plate 8 extending to the lower end position in the fixing hole 3, and the pressure plate 8 having an arc-shaped structure adapted to the cable.

[0024] By setting the pressure plate 8 into an arc-shaped structure that is compatible with the cable, the contact area with the cable is increased to prevent the cable from slipping. The spring 7 is sleeved on the positioning post 9 and plays a reset role. When the pressure plate 8 is not under force, the spring 7 drives the pressure plate 8 and the positioning post 9 back to the initial position.

[0025] A rotating shaft 10 is rotatably mounted on the fixed plate 1, and a turntable 11 and a winding roller 13 for winding the cable are fixedly mounted on the rotating shaft 10. The winding roller 13 has a positioning hole 14 for positioning the cable. After the cable is connected to the distribution cabinet, there will be a slack cable wire outside the fixed hole 3. Rotating the rotating shaft 10 will drive the winding roller 13 to rotate, and the slack wire can be wound up by the rotating winding roller 13.

[0026] To further explain, before the take-up roller 13 takes up its winding, the two ends of the positioning hole 14 should have a considerable amount of excess thread so that the remaining excess thread can be fully wound onto the take-up roller 13.

[0027] The take-up roller 13 is provided with rubber plugs 15 that extend into the positioning hole 14 and clamp both ends of the cable, according to the instruction manual. Figure 3 As shown, when the rubber plugs 15 at both ends of the positioning hole 14 are pressed into the positioning hole 14, the inner wall of the positioning hole 14 presses against the outer wall of the rubber plug 15, and the rubber plug 15 tightens inward, which acts as a clamp for the cable. In addition, the rubber plug 15 is provided at the contact position between the winding roller 13 and the cable, which can prevent the bent cable from being excessively bent.

[0028] A symmetrically arranged limiting plate 16 is fixedly installed on the take-up roller 13. The limiting plate 16 can effectively prevent the excess wire from getting tangled on the outside of the take-up roller 13 when taking up the excess wire, thereby increasing the amount of excess wire taken up. A protective shell 17 for applying pressure to the cable is also fitted on the limiting plate 16. The protective shell 17 can prevent the cable from being directly exposed and prevent damage caused by direct sunlight. The protective shell 17 is preferably made of PVC material and has a protective paint layer on its outer wall.

[0029] A rubber pad 18 is embedded in the inner wall of the protective shell 17. By embedding the rubber pad 18 in the inner wall of the protective shell 17, the rubber pad 18 can protect the cable wound on the take-up roller 13, and the cable is not easy to loosen.

[0030] The fixing plate 1 is provided with a clamping structure for clamping the turntable 11.

[0031] The clamp structure includes a limiting frame 19 fixedly installed on the fixed plate 1, and a limiting rod 22 extending into the turntable 11 is slidably sleeved inside the limiting frame 19. A second spring 21 is welded between the limiting rod 22 and the limiting frame 19. The second spring 21 plays a reset role. When the lever 23 is not under force, the second spring 21 drives the limiting rod 22 to extend into the limiting hole 12.

[0032] The limiting frame 19 has an L-shaped structure. The limiting frame 19 has a limiting groove 20 for guiding the limiting rod 22. The second spring 21 is horizontally welded to one side of the limiting rod 22 extending into the limiting frame 19. The turntable 11 has three circumferentially distributed limiting holes 12 that cooperate with the limiting rod 22. The limiting rod 22 is integrally connected to a lever 23. After the cable is wound up, the pressure on the lever 23 is released. Under the action of the second spring 21, the limiting rod 22 extends into one of the three limiting holes 12. After the limiting rod 22 extends into the turntable 11, it can prevent the rotating shaft 10 from rotating.

[0033] The functional principle of this utility model can be explained through the following operation methods:

[0034] Place the fixing plate 1 on the side wall of the distribution cabinet, so that the fixing holes 3 on the fixing plate 1 correspond to the power supply of the distribution cabinet;

[0035] One end of the cable extends into the positioning hole 14 inside the winding roller 13 and extends to the lower end of the winding roller 13. The lower end rubber plug 15 is fitted onto the lower end of the cable, and the upper end rubber plug 15 is fitted onto the upper end of the cable. The lower end of the cable is pulled to extend into the fixing hole 3, and the pressure plate 8 is lifted to extend the cable into the distribution cabinet. The operator connects the cable into the distribution cabinet.

[0036] After the cable is connected, there is excess cable at both ends of the take-up roller 13. Press the two rubber plugs 15 so that the rubber plugs 15 extend into the positioning hole 14 and then clamp the cable.

[0037] Manually pull the lever 23 to disconnect the limit lever 22 from the turntable 11. Manually pull the limit plate 16 to rotate, so that the limit plate 16 drives the take-up roller 13 and the rotating shaft 10 to rotate. When the take-up roller 13 rotates, it takes up the excess thread. Manually move the excess thread so that it can be evenly wound on the outer wall of the take-up roller 13.

[0038] After the remaining wire is wound up, release the pull of the lever 23. Under the action of the spring 21, the limiting rod 22 extends into one of the limiting holes 3 12 and presses the two protective shells 17. After the two ends of the protective shells 17 extend onto the limiting plate 16, the rubber pad 18 can squeeze the cable.

[0039] Repeat the above steps to install the next fixing plate 1 according to the wiring position of the distribution cabinet.

[0040] 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.
