[0022] Example

[0023] like Figure 1 As shown, a detachable combined transformer core includes a core body 1. Two clamping blocks 3 are respectively arranged on the front and rear opposite outer sides of the core body 1. The two clamping blocks 3 are symmetrically arranged and locked with each other to form a box-shaped structure for loading and clamping the core body 1. Mounting plates 1 are respectively arranged on the upper and lower sides of the two clamping blocks 3. The upper and lower mounting plates 1 are symmetrically arranged, and the two clamping blocks 3 can be synchronously inserted between the upper and lower mounting plates 1 or slid out between the upper and lower mounting plates 1 after being locked and combined.

[0024] like Figure 2As shown, the clamping block 3 includes a vertical plate 31 and a horizontal plate 32. The vertical plate 31 is in the shape of a square frame with a hollow center, and a plurality of horizontal plates 32 are arranged perpendicular to the vertical plate 31 on one side surface. The plurality of horizontal plates 32 are arranged around the outer periphery of the hollow portion of the vertical plate 31 and form a gap with the edge of the hollow portion of the vertical plate 31. The vertical plate 31 and the plurality of horizontal plates 32 are arranged to form a hollow semi-box shape. In this embodiment, there are four horizontal plates 32, which are continuously connected to form a four-sided shape; the number of horizontal plates 32 can also be more, and can be arranged at intervals. When the two clamping blocks 3 are symmetrically arranged and locked with each other, a box-like structure with a hollow center and enclosed sides is formed.

[0025] Two opposite outer side walls of the vertical plate 31 are further extended outward to form ear plates 35, and the ear plates 35 are provided with guide holes 351 and screw holes 352. After the two clamping blocks 3 are symmetrically arranged, the guide rods 6 can be inserted into the two corresponding guide holes 351 to make the positions of the two clamping blocks 3 relatively stable, and then the bolts 5 can be tightened in the two corresponding screw holes 352 to lock the two clamping blocks 3 with each other.

[0026] The other two opposite outer sides of the vertical plate 31 are respectively provided with supporting legs 33 extending outwards. On the vertical plate 31, the two sides where the ear plates 35 are located and the two sides where the supporting legs 33 are located are staggered. In this embodiment, there are four supporting legs 33, and two are provided on each of the two opposite sides of the vertical plate 31. The longitudinal section of the supporting legs 33 is "L" shaped, and a slider 34 is formed on the side of the supporting legs 33 away from the vertical plate 31. The slider 34 is located directly below the cross plate 32. After the two clamping blocks 3 are symmetrically arranged and locked with each other, the corresponding sliders 34 on the two clamping blocks 3 are merged into one.

[0027] like Figure 3 and 4 As shown, the two mounting plates 2 are respectively arranged on both sides of the clamping block 3 provided with a slider 34, the two mounting plates 2 are symmetrically arranged, and the two mounting plates 2 are further provided with a slide groove 21 on one side facing the clamping block 3. The two sliders 34 combined into one body match the slide groove 21 and can be inserted into the slide groove 34 for sliding.

[0028] A locking assembly for locking the position of the slider 34 in the slide groove 21 is also provided on the mounting plate 2. The locking assembly includes a fixed stop block 41 and an elastic stop block 42 provided on the mounting plate 2.

[0029] The fixed limit block 41 is located on the outside of the slide groove 21. When the slider 34 is in the slide groove 21, the "L"-shaped support leg 33 is located on the outside of the slide groove 21. At this time, the positions of the fixed limit block 41 and the support leg 33 correspond to each other. The fixed limit block 41 can limit the unidirectional sliding of the slider 34 by contacting the side wall of the support leg 33.

[0030] The elastic stopper 42 is also located outside the slide groove 21. The elastic stopper 42 includes a shell 421 fixedly mounted on the surface of the mounting plate 2; a pull rod 422 and a slide rod 423 are mounted inside the shell 421, and the pull rod 422 and the slide rod 423 are parallel to each other and are arranged parallel to the surface of the mounting plate 2. The end of the pull rod 422 away from the slide groove 21 passes through the side wall of the shell 421 and can slide telescopically relative to the shell 421. The end of the pull rod 422 close to the slide groove 21 is fixedly connected to a stopper 424, and the side of the stopper 424 facing the slide groove 21 is a right-angled triangle, and a spring 425 is sleeved on the outer side of the slide rod 423, and the spring 425 is connected between the inner side wall of the shell 421 and the stopper 424. The end of the slide rod 423 away from the slide groove 21 passes through the side wall of the shell 421 and is formed with a pull handle, and the pull handle is located outside the shell 421. The end of the slide bar 423 close to the slide slot 21 is fixedly connected to the block 424. Under normal conditions, the block 424 extends out of the outer side of the shell 21, and the position of the block 424 corresponds to the position of the support leg 33. The vertical surface of the block 424 of the right triangle is perpendicular to the slide slot 21 and is located on the side close to the fixed limit block 41, and the inclined surface of the block 424 of the right triangle is located on the side away from the fixed limit block 41. Moreover, the distance between the fixed limit block 41 and the elastic limit block 42 is equal to the distance between the outer side walls of the two support legs 33 on the same side of the vertical plate 31. The block 424 cooperates with the fixed limit block 41 to lock or unlock the sliding of the slider 34 in the slide slot 21.

[0031] During installation, the slider 34 can slide into the slide groove 21 from one side of the inclined surface of the stopper 424 until the support leg 33 contacts the inclined surface of the stopper 424, and the slider 34 can continue to slide, and the support leg 33 pushes the stopper 424 to retract into the shell 421, and the slider 34 continues to slide until the support leg 33 contacts the fixed limit block 41. At this time, the two support legs 33 on the same side of the clamping block 3 are both between the fixed limit block 41 and the elastic limit block 42, and the stopper 424 also returns to the state of extending out of the shell 421 under the action of the spring 425. When the clamping block 3 needs to be taken out, the pull rod 422 is pulled to retract the stopper 424 into the shell 421, and the clamping block 3 can be slid out in the opposite direction.
