Description

Technical Field

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

[0002] A distribution cabinet (also known as a distribution box) is a type of electrical equipment whose main function is to distribute, control, and protect electrical energy. It is usually installed at the end of a power system to safely and orderly distribute electrical energy to various electrical devices or units.

[0003] As described in announcement number CN218887811U, a cable fixing device for insulating columns in a distribution cabinet includes a cable rack, cable fixing components, post insulators, insulating columns, and cables. The cable rack has a cable rack groove. The cable fixing components are installed in the cable rack groove. The post insulator includes a post insulator base, which is positioned on and fixed to the cable rack in the cable rack groove, and is located above the cable fixing components. The insulating columns are mounted on a high-voltage enclosure. The cable is led out from the cable rack groove, passes through the space between the cable fixing components and the post insulator base, and connects to the insulating columns from bottom to top. The cable is fixed by the cable fixing components. This cable fixing device using insulating columns reduces the portion of the cable that is bent into an arc shape to avoid the post insulator, thus avoiding waste of cable materials and preventing leakage caused by the cable drooping and contacting the post insulator.

[0004] This patent avoids the waste of cable materials and prevents leakage caused by cables drooping and contacting the support insulator. However, most cables in existing distribution cabinets are fixed by cable fasteners, which are inconvenient and cumbersome to disassemble or install. Therefore, we propose a new cable fixing device for the insulating column in the distribution cabinet. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, most of the cables in the existing power distribution cabinets are fixed by cable fasteners, which is inconvenient and cumbersome to disassemble or install.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable fixing device for insulating columns in a distribution cabinet, comprising a distribution cabinet body, a cable fixing assembly provided on the inner wall of the rear end of the distribution cabinet body, the cable fixing assembly comprising a main support frame, side ears connected at all four corners of the main support frame, a groove formed on the inner wall of the main support frame, a secondary support frame connected to the surface of the main support frame, threaded holes equally spaced inside the secondary support frame, sliding grooves formed at the upper and lower ends of the threaded holes, a threaded rod connected inside the threaded holes, a fixing plate connected to the front end of the threaded rod, a handle connected to the rear end of the threaded rod, sliding rods connected to the upper and lower ends of the fixing plate near the handle, and bolts inserted at all four corners of the secondary support frame.

[0007] Furthermore, the bolt passes through the secondary support frame and forms a threaded connection with the side lug. The position and size of the bolt match the position and size of the side lug. By disassembling the bolt, the entire secondary support frame can be disassembled, thereby facilitating the removal of all cables.

[0008] Furthermore, the threaded rod is rotatably connected to the fixed clamping plate via a bearing. The front surface of each set of fixed clamping plates is provided with a slot that matches the groove. The rotatable connection can prevent the fixed clamping plate from rotating when the threaded rod rotates. The clamping and fixing of the cable can be achieved through the cooperation of the groove and the slot.

[0009] Furthermore, the outer surface of the slide rod is in contact with the inner wall of the slide groove, and a sliding connection is formed between the slide rod and the slide groove. The sliding connection can improve the accuracy of the fixed clamping plate movement and improve the clamping effect.

[0010] Furthermore, the inner wall of the groove is fitted to the inner wall of the cable, and the slide rod is cylindrical in shape.

[0011] Furthermore, a protective component is provided on the inner wall of the main body of the power distribution cabinet near the fan blades. The protective component includes a connecting block and can reduce the impact force when the fan blades are closed.

[0012] Furthermore, the connecting block is equipped with two sets of springs, and the front ends of the two sets of springs are connected to push plates. As the main buffer element, the springs can effectively absorb and disperse the energy generated by the impact, so that the top block can completely retract into the connecting block after being impacted, reducing the impact force when the fan blades close.

[0013] Furthermore, a top block is connected to the front end of the push plate, and a rubber pad is provided at the front end of the top block.

[0014] Furthermore, the outer surface of the push plate is in contact with the inner wall of the connecting block, and the push plate and the spring form an elastic structure.

[0015] Furthermore, the top block is rectangular in shape, and the position of the connecting block matches the position of the fan blades of the main body of the power distribution cabinet.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] In this invention, the position of the fixing plate can be adjusted by rotating the handle, thereby completing the quick disassembly of the cable without the need for additional cable fixing parts. Furthermore, the fixing method of this application makes the cable neater and smoother, reducing safety hazards.

[0018] In this invention, when the fan blades of the main body of the distribution cabinet are closed, they will contact the top block. The spring reduces the impact force when the fan blades are closed, thereby improving the service life of the main body of the distribution cabinet and avoiding the problem that the main body of the distribution cabinet is easily damaged by the large impact force when the fan blades are closed.

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Examples, such as Figure 1 - Figure 4 As shown, this utility model provides a cable fixing device for an insulating column in a distribution cabinet, including a distribution cabinet body 1. A cable fixing assembly 2 is provided on the inner wall of the rear end of the distribution cabinet body 1. The cable fixing assembly 2 includes a main support frame 201, with side ears 202 connected to each of the four corners of the main support frame 201. A groove 203 is formed on the inner wall of the main support frame 201. A secondary support frame 204 is connected to the surface of the main support frame 201. Threaded holes 205 are equidistantly formed inside the secondary support frame 204. Sliding grooves 206 are formed inside the upper and lower ends of the threaded holes 205. A threaded rod 207 is connected inside the threaded hole 205. A fixing clamp 209 is connected to the front end of the threaded rod 207, and a handle 2 is connected to the rear end of the threaded rod 207. 08. The upper and lower ends of the fixed clamping plate 209 near the throttle 208 are connected to the sliding rod 210. Bolts 211 are inserted at the four corners of the auxiliary support frame 204. The bolts 211 pass through the auxiliary support frame 204 and form a threaded connection with the side ears 202. The position and size of the bolts 211 match the position and size of the side ears 202. The threaded rod 207 forms a rotatable connection with the fixed clamping plate 209 through the bearing. The front surface of each set of fixed clamping plates 209 is provided with a groove that matches the groove 203. The outer surface of the sliding rod 210 fits against the inner wall of the groove 206. The sliding rod 210 and the groove 206 form a sliding connection. The size of the inner wall of the groove 203 fits against the inner wall of the cable. The sliding rod 210 is cylindrical in shape.

[0028] The overall effect of Embodiment 1 is as follows: when fixing the cables on the insulating columns in the main body 1 of the distribution cabinet, the cables to be fixed can be first inserted into the grooves 203 in sequence, and then the handle 208 can be rotated forward, so that the handle 208 can drive the threaded rod 207 to rotate. While the threaded rod 207 rotates forward, it will also rotate forward with the auxiliary support frame 204 through the threaded hole 205. This allows the threaded rod 207 to push the fixing clamp 209 towards the cable through the bearing, and clamp and fix the cable. Then, each group of cables can be fixed in sequence. When it is necessary to disassemble a certain group of cables, the handle 208 at the corresponding position can be rotated in the opposite direction to drive the threaded rod 207 to rotate in the opposite direction. This allows the threaded rod 207 to reverse its direction with the secondary support frame 204 through the threaded hole 205, causing the threaded rod 207 to rotate in the opposite direction. This, in turn, moves the fixing plate 209 away from the surface of the cable, allowing the cable to be pulled out. When all cables need to be disassembled, all four sets of bolts 211 can be removed to disassemble the secondary support frame 204. Then, all the cables can be pulled out, and finally, the secondary support frame 204 can be fixed with bolts 211. This eliminates the need for additional cable fasteners and makes the cables neater and smoother, reducing safety hazards.

[0029] Example 2, as Figure 1 and Figure 5 As shown, a protective component 3 is provided on the inner wall of the main body 1 of the power distribution cabinet near the fan blade. The protective component 3 includes a connecting block 301. Two sets of springs 302 are provided inside the connecting block 301. The front ends of the two sets of springs 302 are connected to a push plate 303. The front ends of the push plate 303 are connected to a top block 304. A rubber pad is provided at the front end of the top block 304. The outer surface of the push plate 303 is in contact with the inner wall of the connecting block 301. The push plate 303 and the springs 302 form an elastic structure. The top block 304 is rectangular in shape. The position of the connecting block 301 matches the position of the fan blade of the main body 1 of the power distribution cabinet.

[0030] The effect achieved by the entire embodiment 2 is that when the fan blades of the main body 1 of the power distribution cabinet are closed, the fan blades will contact and impact the top block 304. After being impacted by the fan blades, the top block 304 will act as a transmission component, pushing the push plate 303 to further compress the spring 302. As the main buffer element, the spring 302 can effectively absorb and disperse the energy generated by the impact, so that the top block 304 can completely retract into the connecting block 301 after being impacted, reducing the impact force when the fan blades are closed, improving the service life of the main body 1 of the power distribution cabinet, and avoiding the problem that the impact force of the fan blades closing is too large and easily causes damage to the main body 1 of the power distribution cabinet.

[0031] Working principle: The position of the fixed clamp 209 can be adjusted by rotating the handle 208, thereby completing the quick disassembly of the cable without the need for additional cable fixing parts. When all cables need to be disassembled, all four sets of bolts 211 can be removed to complete the overall disassembly of the secondary support frame 204. Then, all cables can be pulled out. Finally, the secondary support frame 204 can be fixed with bolts 211. The fixing method of this application can make the cables neater and smoother, reducing safety hazards. When the fan blades of the distribution cabinet body 1 are closed, they will contact the top block 304. The spring 302 reduces the impact force when the fan blades are closed, improves the service life of the distribution cabinet body 1, and avoids the problem that the large impact force when the fan blades are closed can easily damage the distribution cabinet body 1.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
