Description

Technical Field

[0001] This utility model relates to the technical field of distribution boxes, and in particular to a prefabricated frame for distribution boxes. Background Technology

[0002] The distribution box is the "main power switch" of a home. It divides the incoming thick power lines into multiple thinner lines, controlling and protecting the lights and sockets in each room, much like the "traffic control center" of electricity. When using a distribution box, it needs to be fixed in a designated location, which is usually done using a prefabricated frame.

[0003] When using a prefabricated frame for a distribution box, workers first need to fix the frame to the wall and then install the distribution box on it. However, if the wall is uneven or tilted, the distribution box installed on the prefabricated frame will also have a certain tilt angle. The tilt will pull on the wires and terminals inside the box, causing the terminals to loosen or the insulation layer of the wires to wear, resulting in poor contact, short circuit or open circuit. Therefore, when the prefabricated frame is not horizontal, workers may adjust the tilt angle of the distribution box by adding shims to the bottom of the box. However, the shims may fall off after long-term use, which may still cause the distribution box to tilt. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a prefabricated frame for a distribution box. By setting the included angle of the prefabricated frame to be adjustable, the included angle of the prefabricated frame can be adjusted according to the tilt angle when the prefabricated frame is fixed. This ensures that the distribution box installed on the prefabricated frame is in a horizontal position, avoiding loose terminals or wear of wire insulation caused by the tilt of the distribution box.

[0006] To achieve the above objectives, the first aspect of this utility model provides a prefabricated frame for a distribution box, comprising: a connecting frame, a support assembly, and a telescopic assembly, wherein the telescopic assembly is disposed on the support assembly; the support assembly includes a support rod, a movable rod, and an adjustment assembly, wherein the support rod is pivotally connected to the connecting frame; the movable rod is pivotally connected to the support rod; and the adjustment assembly is disposed at the bottom of the connecting frame.

[0007] In addition, the prefabricated frame for the distribution box proposed above according to this utility model may also have the following additional technical features: Specifically, the telescopic assembly includes a telescopic rod, a fixed tube, and a limiting component. The supporting component has a connecting groove; the telescopic rod is slidably connected to the connecting groove; the fixed tube is connected to the supporting component; the telescopic rod has an adjusting groove; the limiting component is disposed inside the fixed tube; the supporting component has a first connecting hole; and the telescopic rod has a second connecting hole.

[0008] Specifically, the limiting component includes a limiting post, a connecting piece, a spring, and a pull ring.

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The prefabricated frame for the distribution box of this utility model is described below with reference to the accompanying drawings.

[0017] like Figures 1-6 As shown, the prefabricated frame for the distribution box in this embodiment of the present invention includes: a connecting frame 1, a support component 2, and a telescopic component 3.

[0018] The telescopic component 3 is mounted on the support component 2, which includes a support rod 21, a movable rod 22, and an adjustment component 23.

[0019] Among them, the support rod 21 is pivotally connected to the connecting frame 1, the movable rod 22 is pivotally connected to the support rod 21, and the adjustment component 23 is located at the bottom of the connecting frame 1.

[0020] The adjustment assembly 23 includes a threaded post 231, a limit plate 232, a turntable 233, an adjustment block 234, and a fixing rod 237.

[0021] The threaded post 231 penetrates the bottom of the connecting frame 1, the limiting plate 232 is provided on the outer wall of the threaded post 231, the turntable 233 is connected to the other end of the threaded post 231, the adjusting block 234 is threadedly connected to the threaded post 231, the adjusting block 234 is provided with a fixing hole 235, the turntable 233 is provided with an adjusting hole 236, the fixing rod 237 is installed in the fixing hole 235, and the other end of the fixing rod 237 passes through the corresponding adjusting hole 236.

[0022] It should be noted that the upper end of the fixing rod 237 described in this embodiment is disc-shaped, and the diameter of the disc is larger than the diameter of the fixing hole 235. The diameters of the fixing hole 235 and the adjusting hole 236 are equal and the same as the diameter of the position below the disc of the fixing rod 237. In this way, the fixing rod 237 can pass through the fixing hole 235 and the adjusting hole 236 and remain on the adjusting block 234 to fix the turntable 233. The distance between the turntable 233 and the limiting plate 232 is the same as the thickness of the bottom of the connecting frame 1. In this way, the turntable 233 can be fixed at the bottom of the connecting frame 1 and will not move up and down. The width of the adjusting block 234 plus the thickness of the movable rod 22 is the same as the width of the inner wall of the connecting frame 1. In this way, the support rod 21 can only move up and down on the inner wall of the connecting frame 1 and cannot rotate.

[0023] Specifically, when it is necessary to adjust the angle between the support rod 21 and the connecting frame 1, the operator first removes the fixing rod 237 from the fixing hole 235 and the adjusting hole 236. Then, the turntable 233 is rotated to drive the threaded post 231 at one end of the turntable 233 to rotate. Since the adjusting block 234 is restricted by the inner wall of the movable rod 22 and the connecting frame 1 and cannot rotate with the threaded post 231, the rotation of the threaded post 231 will drive the adjusting block 234 to move up and down. In this way, the movable rod 22 will rotate at the pivot connection with the adjusting block 234, causing the support rod 21 and the movable rod 22 to rotate, thereby adjusting the angle between the support rod 21 and the connecting frame 1.

[0024] After the angle is adjusted, the fixing rod 237 is passed through the fixing hole 235 and then into the corresponding adjustment hole 236 to fix the turntable 233, thereby fixing the included angle to adapt to different installation environments.

[0025] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, the telescopic assembly 3 includes a telescopic rod 32, a fixing tube 33, and a limiting assembly 35.

[0026] The support component 2 has a connecting groove 31, the telescopic rod 32 is slidably connected to the connecting groove 31, the fixed tube 33 is connected to the support component 2, the telescopic rod 32 has an adjustment groove 34, the limiting component 35 is set in the fixed tube 33, the support component 2 has a first connecting hole 36, and the telescopic rod 32 has a second connecting hole 37.

[0027] The limiting component 35 includes a limiting post 351, a connecting piece 352, a spring 353, and a pull ring 354.

[0028] Among them, the limiting post 351 is slidably connected to the fixed tube 33, the connecting piece 352 is connected to the other end of the limiting post 351, the spring 353 is sleeved on the outside of the fixed tube 33, and the two ends of the spring 353 are respectively connected to the connecting piece 352 and the support assembly 2, and the pull ring 354 is set on the connecting piece 352.

[0029] It should be noted that the length of the fixing tube 33 described in this embodiment is less than the length of the limiting post 351, so that the limiting post 351 can pass through the fixing tube 33 and enter the adjusting groove 34 to fix the telescopic rod 32.

[0030] Specifically, when the size of the prefabricated frame needs to be adjusted when replacing the distribution box, the worker first pulls the pull ring 354, which drives the limiting post 351 to move downwards on the inner wall of the fixed tube 33 through the connecting piece 352. At this time, the spring 353 is stretched as the limiting post 351 moves. Then, one end of the fixed tube 33 is completely separated from the adjusting groove 34 and enters the fixed tube 33. Then, force is applied to the telescopic rod 32 to make it move outwards in the connecting groove 31. After the telescopic rod 32 is adjusted to the appropriate position, the hand that pulls the pull ring 354 makes the limiting post 351 push into the corresponding adjusting groove 34 under the action of the spring 353 to fix the telescopic rod 32. Then, the bolt is passed through the second connecting hole 37 and the first connecting hole 36 to connect to the distribution box, thus fixing the distribution box on the prefabricated frame.

[0031] In one embodiment of this application, such as Figure 1 As shown, a pre-embedded plate 4 is provided on the outer wall of the connecting frame 1.

[0032] It should be noted that the embedded plate 4 described in this embodiment can be fixed to the connection point on the wall for fixing the bracket by passing through the connection hole opened on the embedded plate 4 with bolts or other tools.

[0033] In summary, by making the included angle of the prefabricated frame adjustable, the included angle of the prefabricated frame can be adjusted according to the tilt angle when the prefabricated frame is fixed. This ensures that the distribution box installed on the prefabricated frame is in a horizontal position, avoiding loose terminals or wear of wire insulation caused by the tilt of the distribution box.
