[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Figures 1-7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 7 The present invention will be further described below.

[0024] An electrical equipment installation lifting bracket includes: two brackets 1, spaced apart, a transformer 2 mounted on the top surface of each bracket 1, and first bolts 3 at the four corners of each transformer 2, connecting the brackets 1 and the transformer 2 via the first bolts 3; two fixed posts 8 are fixedly connected to the bottom surfaces of the two brackets 1, a low-voltage distribution cabinet 7 is mounted on the bottom surface of each fixed post 8, a lifting component is mounted on the bottom surface of each bracket 1, and a insertion slot 13 is provided inside each fixed post 8, with a mounting bracket 7 installed inside the insertion slot 13. The mounting component includes two plug-in blocks 12, both of which are fixedly connected to the top surface of the low-voltage distribution cabinet 7. The plug-in blocks 12 are movably plugged into the plug-in slot 13. The plug-in slot 13 has a movable part inside. A slot 14 is opened on one side of the plug-in block 12. When the mounting component moves upward along the inner wall of the plug-in slot 13 and pushes the movable part to the inner top wall of the plug-in slot 13, the limiting part enters the slot 14.

[0025] Specifically, the movable component includes: a movable frame 21, which is movably connected inside the insertion slot 13. The movable frame 21 has an L-shaped structure, and a movable hole 24 is provided on one side of the inner slot 19. The movable hole 24 is connected to the insertion slot 13. One end of the movable frame 21 extends into the inner slot 19 through the movable hole 24. Two guide rods 22 are fixedly connected inside the movable hole 24. Two round holes are provided on the top surface of the movable frame 21. The movable frame 21 is slidably connected to the guide rods 22 through the round holes. The movable component also includes: two second return springs 23, which are fixedly connected to the top surface of the movable frame 21. The second return springs 23 are located outside the guide rods 22, and one end of the second return springs 23 is fixedly connected to the inner top wall of the movable hole 24.

[0026] In this embodiment, when the movable frame 21 is subjected to force and moves upward inside the movable hole 24 and squeezes the second return spring 23, the guide rod 22 can guide the movable frame 21.

[0027] Specifically, the limiting component includes: a locking plate 16, which is movably connected inside the inner groove 19. One end of the locking plate 16 passes through the inner groove 19 and is movably inserted into the locking slot 14. A limiting slot 15 is formed on the top surface of the locking plate 16, which is movably inserted into the movable frame 21. Two first return springs 20 are fixedly connected to one side of the locking plate 16, and one end of the first return spring 20 is fixedly connected to the inner side wall of the inner groove 19.

[0028] In this embodiment, when the movable frame 21 enters the interior of the limiting groove 15, the card plate 16 is limited and will not move. When the movable frame 21 is lifted by the plug-in block 12, one end of the movable frame 21 moves away from the interior of the limiting groove 15. At this time, the potential energy of the first reset spring 20 is released, which can push the card plate 16 into the interior of the card slot 14, thereby achieving the limiting effect on the plug-in block 12.

[0029] Specifically, the limiting component also includes: two guide posts 18, both of which are fixedly connected to the inner bottom wall of the inner groove 19; two guide grooves 26 are opened on the bottom surface of the clamping plate 16, the guide grooves 26 are slidably connected to the guide posts 18; an operating rod 17 is fixedly connected to one side of the clamping plate 16; a sliding hole 25 is opened on one side of the fixed post 8; one end of the operating rod 17 passes through the sliding hole 25 and extends to the outside of the fixed post 8; and the operating rod 17 is movably connected to the sliding hole 25.

[0030] In this embodiment, by setting the operating lever 17, when the low-voltage distribution cabinet 7 is disassembled later, the operating lever 17 can be pulled, so that the operating lever 17 drives the clamping plate 16 into the inner groove 19 and squeezes the first return spring 20 until the clamping plate 16 is completely inside the inner groove 19. At this time, the output end of the electric push rod 4 extends, driving the support plate 5 and the low-voltage distribution cabinet 7 to move downward, so that the low-voltage distribution cabinet 7 drives the plug block 12 to move downward and disengage from the plug slot 13, achieving the effect of separating the fixed column 8 and the plug block 12, and the low-voltage distribution cabinet 7 can be disassembled. At this time, the moving frame 21 gradually loses the force of the plug block 12. Under the release of the potential energy of the second return spring 23, the moving frame 21 resets and enters the limit groove 15, achieving the effect of limiting the clamping plate 16, waiting for the next installation operation.

[0031] Specifically, the lifting components include: two electric push rods 4, both of which are fixedly connected to the bottom surface of the bracket 1; a support plate 5 is provided on the bottom surface of the low-voltage distribution cabinet 7; the output end of the electric push rod 4 is fixedly connected to the support plate 5; a positioning frame 6 is fixedly connected to the top surface of the support plate 5; the low-voltage distribution cabinet 7 is movably inserted into the positioning frame 6; two round holes are opened on the inner side wall of the bracket 1; a second bolt 9 is provided in the round hole; the two brackets 1 are connected by the second bolt 9; two fixed frames 10 are fixedly connected to the side of the two brackets 1 that are close to each other; round holes are opened on both sides of the fixed frames 10; a third bolt 11 is provided inside the round hole; and each pair of fixed frames 10 are connected by the third bolt 11.

[0032] In this implementation scheme, the fixed frame 10 can be attached to the utility pole by the worker, and then the fixed frame 10 can be fixed to the utility pole by the third bolt 11. Then the two brackets 1 can be fixed together by the second bolt 9, and the two brackets 1 can be fixed to the utility pole. Then the worker can fix the transformer 2 to the bracket 1 by the first bolt 3, so that the bracket 1 can support the transformer 2.

[0033] The working principle and usage process of this utility model are as follows: In use, the operator can attach the fixing bracket 10 to the utility pole, and then fix the fixing bracket 10 to the utility pole using the third bolt 11. Then, the two brackets 1 are fixed together using the second bolt 9, thus fixing the two brackets 1 to the utility pole. The operator can then fix the transformer 2 to the bracket 1 using the first bolt 3, allowing the bracket 1 to support the transformer 2. Next, the operator places the low-voltage distribution cabinet 7 into the positioning frame 6 for pre-positioning. At this time, the output end of the electric push rod 4 retracts, causing the support plate 5 to move upwards, thus moving the low-voltage distribution cabinet 7. As the low-voltage distribution cabinet 7 moves upwards, it will cause the plug-in block 12 to enter the plug-in slot 13. During this process, the plug-in block 12 will first be inside the plug-in slot 13. The moving part moves and lifts the moving frame 21. The moving frame 21 moves upward inside the moving hole 24 and squeezes the second return spring 23. At the same time, the guide rod 22 can guide the moving frame 21. When the top surface of the moving frame 21 contacts the inner top wall of the plug-in groove 13, the moving frame 21 disengages from the inside of the limiting groove 15, thereby releasing the limitation on the card plate 16. At this time, the potential energy of the first return spring 20 is released, which drives the card plate 16 to move into the inside of the card slot 14. At this time, the electric push rod 4 is turned off, and the installation effect of the plug-in block 12 and the fixing column 8 is completed, achieving the effect of installing the low-voltage distribution cabinet 7 on the bracket 1, ensuring the stability of the low-voltage distribution cabinet 7 during use, and the installation strength is low and the installation efficiency is high. When the card plate 16 moves, the card plate 16 will slide on the guide column 18 through the guide groove 26, thereby ensuring that the card plate 16 will not deviate when moving.

[0034] The above description is merely a preferred embodiment of this utility model and is 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. 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 its technical solution shall still fall within the protection scope of this utility model.
