[0012] Further, two lifting mechanisms are provided, and the two lifting mechanisms are arranged at the diagonal positions of the transformer box body.

[0013] By adopting the above technical solution, two lifting mechanisms are provided, and the two lifting mechanisms are arranged at the diagonal positions of the transformer box body, ensuring the stability and balance of the box cover during the lifting process.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0029] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0030] A transformer that is convenient for disassembly, maintenance and replacement, as Figures 1 - 4 shown, includes a transformer box body 1. A support edge 4 is fixedly connected to the top of the transformer box body 1. A box cover 2 is arranged on the top of the support edge 4. A lifting mechanism 3 is fixedly connected to the box cover 2. The lifting mechanism 3 includes a mounting block 301. A rotating hole 302 is opened inside the mounting block 301. A rotating block 303 is rotatably connected inside the rotating hole 302. A hexagonal block 304 is fixedly connected to the top of the rotating block 303. A stud 305 is fixedly connected to the bottom of the rotating block 303;

[0031] The bottom of the support edge 4 is rotatably connected to an arc-shaped rod 306. An access groove 307 is opened on the arc-shaped rod 306. An arc-shaped surface 308 is fixedly connected to the top of one end of the arc-shaped rod 306. A first screw 309 is threadedly connected inside the arc-shaped surface 308. Through the unique design of the lifting mechanism 3, the box cover 2 can be easily lifted without using external lifting equipment, thus greatly simplifying the disassembly and assembly process of the transformer, improving work efficiency, reducing operation complexity and safety risks. At the same time, the cooperation between the stud 305 and the nut 6 in the lifting mechanism 3, and the cooperation between the arc-shaped rod 306 and the arc-shaped surface 308, through the locking of the first screw 309 and the second screw 310, ensure that the nut 6 remains locked during the lifting process to prevent the situation of coming off.

[0032] Refer to Figure 3 , a cross plate 5 is fixedly connected to one side of the transformer box body 1. By fixedly connecting the cross plate 5 to one side of the transformer box body 1, a stable support point is provided for the arc-shaped rod 306, increasing the stability of the lifting mechanism 3 during operation, ensuring that no accidental sliding or deviation occurs when lifting the box cover 2. At the same time, the presence of the cross plate 5 also simplifies the structural design of the lifting mechanism 3, making the entire lifting process smoother and more reliable.

[0033] Refer to Figure 2 , a nut 6 is arranged inside the arc-shaped surface 308. By arranging the nut 6 inside the arc-shaped surface 308, a tight fit with the stud 305 is achieved, providing the necessary threaded connection for the lifting mechanism 3, ensuring the stability and accuracy during the lifting process, enabling the box cover 2 to be lifted smoothly and accurately. At the same time, the setting of the nut 6 also facilitates disassembly and assembly operations. The staff can easily adjust the number of meshing turns between the stud 305 and the nut 6, thereby controlling the lifting height of the box cover 2.

[0034] Refer to Figure 1 and Figure 4, There are two lifting mechanisms 3, and the two lifting mechanisms 3 are arranged at the diagonal positions of the transformer box body 1. The arrangement of the two lifting mechanisms 3 at the diagonal positions of the transformer box body 1 ensures the stability and balance of the cover 2 during the lifting process. The layout at the diagonal positions can effectively prevent the cover from tilting or shifting during lifting, thus guaranteeing the safety of the operation. At the same time, the lifting mechanisms 3 arranged diagonally can also provide a greater lifting force and disperse the pressure on the cover 2, enabling the cover 2 to be lifted more smoothly and efficiently, and reducing the risks that may occur during the operation.

[0035] Refer to Figure 1 and Figure 4 , A terminal post 7 is fixedly connected to the top of the cover 2. There are multiple terminal posts 7. By fixedly connecting multiple terminal posts 7 to the top of the cover 2, it facilitates the electrical connection of the transformer. The multiple terminal posts 7 can simultaneously meet the input and output requirements of multiple circuits, improving the functionality and flexibility of use of the transformer. At the same time, the setting of the terminal posts 7 also facilitates the daily wiring and maintenance operations of the staff. The staff can easily repair the terminal posts 7, thereby realizing the effective monitoring of the working state of the transformer.

[0036] Refer to Figure 1 and Figure 4 , The bottom of the mounting block 301 is fixedly connected to the cover 2. By fixedly connecting the bottom of the mounting block 301 to the cover 2, the stability and reliability of the lifting mechanism 3 are ensured. The fixed connection can effectively prevent the lifting mechanism 3 from moving or loosening during the operation, thus guaranteeing the smooth progress of the lifting of the cover 2. At the same time, the fixed connection between the mounting block 301 and the cover 2 also enhances the rigidity of the overall structure, making the force transmission during the lifting process more direct and effective, capable of withstanding a greater lifting force, and ensuring the safety and durability of the transformer during disassembly, assembly, and maintenance.

[0037] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , A second screw 310 is threadedly connected inside the arc surface 308. By threadedly connecting the second screw 310 inside the arc surface 308, an additional locking mechanism is provided for the arc rod 306. After the nut 6 is placed inside the arc surface 308, by tightening the second screw 310, the position of the nut 6 can be further fixed to prevent it from moving during the lifting process. At the same time, the second screw 310 and the first screw 309 act together to form a double locking system, greatly improving the safety and reliability of the disassembly and assembly process, ensuring the stability and controllability of the cover 2 during the lifting process, and reducing the operation risks.

[0038] The implementation principle of the present utility model is as follows: First, when locking is required, tighten with nut 6 and stud 305, and then tighten other bolts and nuts to complete the installation of the transformer. When removal is needed, first remove other bolts and nuts, and then rotate the arc-shaped rod 306 at the two lifting mechanisms 3. The stud 305 enters the reserved entry slot 307. At this time, one side of the arc-shaped rod 306 is supported by the cross plate 5, and at the same time, the nut 6 enters the interior of the arc-shaped surface 308. Then, tighten the first screw 305. After locking the first screw 305, tighten the second screw 310. The first screw 305 and the second screw 310 press against both sides of the nut 6, making the nut 6 unable to rotate. Then, rotate the hexagonal block 304 at the two lifting mechanisms 3 simultaneously. The hexagonal block 304 drives the stud 305 to rotate through the rotating block 303. Since the nut 6 cannot rotate, the rotation of the stud 305 can drive the lid 2 to rise, completing the lifting of the lid 2 and achieving the effect of being able to lift without a lifting device.

[0039] Parts not involved in the present utility model are the same as or can be implemented using existing technologies, and will not be elaborated here.
