[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] refer to Figure 1-5 This utility model provides the following two technical solutions:

[0024] First embodiment: An oil-immersed transformer that is easy to assemble includes an oil tank 1. The oil tank 1 is connected to an assembly component that is easy to assemble. The assembly component includes: a cover plate 2, which is slidably connected to the upper side of the oil tank 1 and has a transformer assembly at the bottom; a positioning component 4, which is used for mounting the cover plate 2 to the oil tank 1. The positioning component 4 includes two sets of anti-detachment components 44 for preventing the cover plate 2 from detaching from the edge of the oil tank 1. The positioning component 4 also includes a frame 41. A height adjustment component 42 for adjusting the height of the anti-detachment components 44 is installed on the upper side of the frame 41. A movable frame 45 is connected to the upper end of the height adjustment component 42. An adjustment component 43 for adjusting the distance between the two sets of anti-detachment components 44 is connected inside the movable frame 45.

[0025] Positioning blocks 3 are set at the front and rear ends of the outer side of the oil tank 1 to provide support for the frame 41; the height adjustment component 42 includes four sets of one-way screws 424 that are vertically rotatably connected to the frame 41 for adjusting the height of the movable frame 45. All four sets of one-way screws 424 are threadedly connected to the movable frame 45 and are provided with a first anti-detachment block at the top. Four sets of worm gear assemblies 423 for driving the one-way screws 424 are installed inside the frame 41. The front side of the four sets of worm gear assemblies 423 is connected to a pulley assembly 422, and a first handwheel 421 is installed on the front side of the pulley assembly 422.

[0026] The worms in the four sets of worm gear assemblies 423 are coaxially and fixedly connected to the driving pulley and driven pulley in the pulley assembly 422, respectively. The worm gear in the worm gear assembly 423 is coaxially and fixedly connected to the one-way screw 424. The driving pulley in the pulley assembly 422 is coaxially and fixedly connected to the first handwheel 421. The worm gear and worm in the worm gear assembly 423 mesh with each other. The worm gear assemblies 423 on both sides of the frame 41 are symmetrically arranged. The one-way screws 424 on both sides of the frame 41 have opposite thread directions. The top edge of the oil tank 1 and the edge of the cover plate 2 are provided with positioning grooves on the lower side of the anti-detachment parts 44. The positioning block 3 is provided with a sliding groove that slides with the frame 41. The side of the positioning block 3 is provided with a pin for preventing the frame 41 from detaching.

[0027] Adjusting component 43 includes two sets of bidirectional screws 431 rotatably connected to both ends of the inner side of the movable frame 45 along the X-axis. A set of movable frames 434 are threaded to both sides of each set of bidirectional screws 431. Two sets of anti-detachment components 44 are respectively mounted on the two sets of movable frames 434. A set of bevel gear assemblies 432 is connected to the left side of each set of bidirectional screws 431. A second handwheel 433 for providing drive is coaxially fixed to the rear side of the driving bevel gear in each set of bevel gear assemblies 432. The driven bevel gear in the bevel gear assembly 432 is connected to the bidirectional screws 431. 31. Coaxial fixed connection; the second handwheel 433, two sets of bevel gear assemblies 432, and double-direction screw 431 cooperate with each other to adjust the distance between the two sets of movable frames 434 and the anti-detachment parts 44 on their upper side, so that they match the positioning grooves on the edges of the oil tank 1 and the cover plate 2 of the corresponding size, thereby improving the adaptability of the device. Meanwhile, the first handwheel 421 cooperates with the pulley assembly 422, four sets of worm gear assemblies 423, and one-way screw 424 to adjust the height of the adjusting parts 43 and the anti-detachment parts 44, thereby realizing the installation of the oil tank 1 and the cover plate 2.

[0028] The main difference between the second implementation method and the first implementation method is that:

[0029] The anti-detachment component 44 includes a slide rod 444 slidably connected to the movable frame 434, a stop block 442 installed at the bottom of the slide rod 444, a positioning pin 441 for preventing the oil tank 1 and the cover plate 2 from detaching installed at the bottom of the stop block 442, a spring 443 fixedly connected to the top of the movable frame 434 and used to provide cushioning installed at the upper end of the stop block 442, and a second anti-detachment block installed at the bottom of the slide rod 444;

[0030] When the adjusting component 43 drives the positioning pin 441 inside the anti-detachment component 44 to insert into the positioning groove on the edge of the oil tank 1 and the cover plate 2, the stop block 442 gradually contacts the cover plate 2. Under the reaction force of the cover plate 2, the stop block 442 compresses the bottom spring 443 of the moving frame 434. The compression spring 443 generates elastic force to press the stop block 442 tightly against the cover plate 2.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user uses external hoisting equipment to guide the cover plate 2 and its lower transformer assembly into the oil tank 1. After the cover plate 2 is in contact with the top edge of the oil tank 1, the user separates the external hoisting equipment from the cover plate 2 and rotates the second handwheel 433. The second handwheel 433 drives the two sets of movable frames 434 and their upper array of anti-detachment components 44 to move horizontally through two sets of bevel gear assemblies 432 and double-direction screws 431. When the array of anti-detachment components 44 moves to the upper end of the positioning groove on the top edge of the cover plate 2 and the oil tank 1, the user stops rotating the second handwheel 433. The first handwheel 421, pulley assembly 422, and four sets of worm gear assemblies 423 drive the four sets of one-way screws 424 to rotate. The rotating one-way screws 424 vertically adjust the movable frame 45, adjusting component 43, and anti-detachment component 44, so that the positioning pin 441 in the anti-detachment component 44 is inserted into the positioning groove on the top edge of the cover plate 2 and the oil tank 1, thus realizing the assembly of the cover plate 2 and the oil tank 1.
