[0034] Example 2

[0035] Based on the first embodiment, Figure 7-Figure 8 As shown, the side limit assembly 55 includes two side plates 553, which are fixedly connected to the upper side of the support plate 51 and are located on the left and right sides of the transformer 4. A lifting groove 554 is provided on the side of the side plate 553 close to the transformer 4. Two symmetrically distributed lifting blocks 555 are slidably connected to the inner side of the lifting groove 554. The lifting blocks 555 are fixedly connected to the side of the transformer 4. A side limit plate 556 is fixedly connected to the middle of the side plate 553 with a rotating shaft 557. The outer side of the rotating shaft 557 is fixedly connected to the side plate 556. The left and right sides of the lifting plate 5313 are fixedly connected with a control plate 551, the upper side of the control plate 551 is fixedly connected with a connecting block 552, the upper side of the connecting block 552 is fixedly connected with a toothed plate 559 meshing with the gear 558, the outer end of the rotating shaft 557 is fixedly connected with a turntable 5510, the outer side of the turntable 5510 is fixedly connected with two rotating plates 5511, the outer sides of the two rotating plates 5511 are rotatably connected with a second inclined plate 5512, and the second inclined plate 5512 is connected to the lifting block 2. 555 is connected in rotation, two inclined plates 5512 are arranged in parallel, the side limit plate 556 is arranged in an L-shaped structure, the two lifting blocks 555 and the side limit plate 556 are located on the upper and lower sides of the transformer 4. When the base of the transformer 4 is limited, the lifting plate 5313 descends and drives the control plate 551 to descend, the control plate 551 drives the connecting block 552 to descend, the connecting block 552 drives the tooth plate 559 to descend, the tooth plate 559 drives the gear 558 to rotate, and the gear 558 drives the rotating shaft 557 to rotate. The rotating shaft 557 drives the turntable 5510 to rotate, the turntable 5510 drives the rotating plate 5511 to rotate the rod, the rotating plate 5511 drives the inclined plate 2 5512 to rotate, the inclined plate 2 5512 drives the lifting block 2 555 to move. Since the two inclined plates 2 5512 are arranged in parallel, the lifting blocks 2 555 on the upper and lower sides are close to each other, and the lifting block 2 555 drives the side limit plates 556 to move, so that the side limit plates 556 on the upper and lower sides limit the sides of the transformer 4, thereby increasing the stability of the installation of the transformer 4.

[0036] Two bottom blocks 5513 are fixedly connected to the lower side of the side plate 553, and a rotating rod 5514 is rotatably connected between the two bottom blocks 5513.

When installing the transformer 4, the lifting plate 5313 drives the connecting rope 5516 to unfold, and the connecting rope 5516 drives the rotating rod 5514 on the roller 5515 to rotate. When it is necessary to check the tightness of the installation of the transformer 4, the second rotating cap 5517 on the rotating rod 5514 is rotated in the opposite direction. If the second rotating cap 5517 can be rotated, it means that the connecting rope 5516 is loose, the lifting plate 5313 rises, and the transformer 4 is installed loose and needs to be tightened. Otherwise, it means that the installation is qualified, which is convenient for staff to carry out daily quick inspections.

[0037] A baffle 3 is provided on the inner side of the box body 1, and mounting blocks 6 are fixedly connected to the left and right sides of the baffle 3.

The baffle 3 is provided to facilitate protection of the components of the mounting unit 5.

[0038] Working principle: When in use, the staff first places the transformer 4 on the support plate 51, and then rotates the rotating cap 5318, which drives the worm 5317 to rotate. Under the action of the worm gear 5316, the screw 5315, the lifting plate 5313 and the inclined plate 5311, the left and right sliders 531 are controlled to approach each other, and the sliders 531 drive the bottom limit plates 535 to move. Under the action of the vertical plate 532, the lifting block 534, the control block 536, the slide bar 537 and the inclined slot 539, the bottom limit plates 535 on both sides are controlled to move closer to the transformer 4 while descending, so that the bottom limit plates 535 can be easily adjusted to the base of the transformer 4. Limit, at the same time, the lifting plate 5313 drives the control plate 551 to descend, and the control plate 551 drives the tooth plate 559 on the connecting block 552 to descend. Under the action of the gear 558, the rotating shaft 557, the turntable 5510, the rotating plate 5511, the inclined plate 2 5512 and the lifting block 2 555, the side limit plates 556 on the upper and lower sides are controlled to approach each other, which is convenient for limiting the side of the transformer 4 and increasing the stability of the installation of the transformer 4. At the same time, the lifting plate 5313 drives the connecting rope 5516 to unfold. During daily inspections, the staff rotates the rotating cap 2 5517 in the opposite direction. If the rotating cap 2 5517 can rotate in the opposite direction, it means that the installation is loose, otherwise it is qualified.
