[0021] 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.

[0022] Reference Figures 1-5 A box-type transformer that is easy to disassemble includes a square frame 1 and a box 2. Connecting seats 3 are symmetrically fixedly installed on the bottom of the box 2. The upper surface of the square frame 1 is symmetrically provided with slots. Two connecting seats 3 are respectively inserted into two slots. Multiple limiting slots 4 are provided on the opposite side of the two connecting seats 3. Two movable seats 5 are symmetrically slidably installed on the square frame 1. The two movable seats 5 are located between the two connecting seats 3. Multiple limiting rods 6 are fixedly installed on the side of the movable seats 5 near the connecting seats 3. One end of the multiple limiting rods 6 is respectively inserted into the multiple limiting slots 4. The square frame 1 is provided with a transmission component for driving the two movable seats 5 to move relative to each other.

[0023] When the box-type transformer is installed on the square frame platform 1, the two connecting seats 3 are inserted into the two slots respectively, thereby restricting the box body 2 from moving forward, backward, left and right. At the same time, the multiple limiting rods 6 on the moving seat 5 are inserted into the multiple limiting slots 4 on the connecting seat 3 respectively, thereby restricting the box body 2 from moving upward, thus locking the box body 2 on the square frame platform 1, and completing the installation of the box-type transformer.

[0024] A rectangular groove is provided in the middle part of the frame platform 1. The transmission component includes a threaded rod 7 with opposite thread directions at the left and right ends, which is horizontally rotatably installed in the rectangular groove; two symmetrical moving blocks 8 that are threaded onto the threaded rod 7; two support blocks 9 that are respectively fixedly installed on the two moving blocks 8; and a drive component for driving the threaded rod 7 to rotate. The two support blocks 9 are respectively fixedly connected to two moving seats 5. The two moving blocks 8 slide horizontally in the rectangular groove. An installation groove communicating with the rectangular groove is provided on the upper surface of the frame platform 1. The drive component includes a drive motor 10 fixedly installed in the installation groove; a first bevel gear 11 fixedly installed on one end of the output shaft of the drive motor 10; and a second bevel gear 12 fixedly sleeved on the threaded rod 7. The first bevel gear 11 and the second bevel gear 12 are meshed together.

[0025] When it is necessary to disassemble the box-type transformer, start the drive motor 10 to drive the first bevel gear 11 to rotate. Since the first bevel gear 11 is meshed with the second bevel gear 12, the threaded rod 7 will be driven to rotate through the second bevel gear 12. Since the threads at the left and right ends of the threaded rod 7 are opposite, the threaded rod 7 can drive the two moving blocks 8 to move closer to each other during rotation. At the same time, the two support blocks 9 drive the two moving seats 5 to move closer to each other. When the moving seats 5 move, they will drive one end of the limit rod 6 to be pulled out from the limit groove 4, thereby releasing the restriction on the upward movement of the connecting seat 3. At this time, the box body 2 can be lifted upward, and the disassembly of the box-type transformer can be completed. The operation is simple and reduces manpower, material resources and time.

[0026] A U-shaped groove is provided on the rectangular platform 1, and a U-shaped waterproof frame 13 is vertically slidably installed in the U-shaped groove. The rectangular platform 1 is equipped with two sets of lifting components, each used to drive the waterproof frame 13 vertically upward. The lifting components include two L-shaped rods 14 respectively fixedly installed at both ends of the movable base 5, two triangular blocks 15 respectively fixedly installed at one end of the two L-shaped rods 14, and two top rods 16 symmetrically fixedly installed on the waterproof frame 13. One end of each top rod 16 contacts the inclined surface of the two triangular blocks 15. When the two movable bases 5 are moved away from each other, the lifting components... The movable seat 5 will drive the triangular block 15 to move towards the top rod 16 via the L-shaped rod 14. One end of the top rod 16 contacts the inclined surface of the triangular block 15. The inclined surface of the triangular block 15 can drive the waterproof frame 13 to move upward until the waterproof frame 13 contacts the bottom of the box 2. A sealed space is formed between the box 2, the square frame platform 1 and the waterproof frame 13. The various metal parts of the movable seat 5, the connecting seat 3 and the limiting rod 6 are in the sealed space, which can prevent rainwater from wetting the connecting seat 3, the movable seat 5 and the limiting rod 6 in rainy weather, causing rust and making it inconvenient to disassemble later.

[0027] A sealing strip is fixedly installed on the upper end of the waterproof frame 13. The sealing strip is made of rubber. When the waterproof frame 13 contacts the bottom of the box 2, the sealing strip can improve the sealing between them.

[0028] In this invention, when the box-type transformer is installed on the square frame 1, the two connecting seats 3 are respectively inserted into the two slots, thereby restricting the front-back and left-right movement of the box body 2. At the same time, the multiple limiting rods 6 on the moving seat 5 are respectively inserted into the multiple limiting slots 4 on the connecting seat 3, thereby restricting the upward movement of the box body 2, thus locking the box body 2 on the square frame 1 and completing the installation of the box-type transformer. When disassembly is required, the two moving seats 5 are driven to move closer to each other through the transmission component. When the moving seat 5 moves, it will drive one end of the limiting rod 6 to be pulled out from the limiting slot 4, thereby releasing the restriction on the upward movement of the connecting seat 3. At this time, the box body 2 can be lifted upward, and the disassembly of the box-type transformer can be completed. The operation is simple and reduces manpower, material resources and time.

[0029] 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.
