[0028] For examples, see Figure 1-4 , the utility model provides a technical solution:

[0029] A low-voltage cabinet comprises a cabinet body 1 and a cabinet body 2 arranged on the top of the cabinet body 1, the rear surfaces of the cabinet body 1 and the cabinet body 2 are both provided with a cabinet door 3, a convenient splicing mechanism 4 is provided between the cabinet body 1 and the cabinet body 2, an installation chamber 5 is provided inside the cabinet body 1 and the cabinet body 2, a mounting frame 501 and a bearing plate 502 are provided inside the mounting chamber 5, a slide groove 503 and a clamping hole 504 are provided on the right side surface of the mounting frame 501, a plurality of sliding support blocks 505 are provided inside the slide groove 503, a mounting block 506 is fixedly installed at the bottom of the sliding support block 505, a reset spring 507 is fixedly provided on the right side surface of the mounting block 506, and a clamping column 508 is movably provided inside the reset spring 507;

[0030] Specifically, the mounting frame 501 is mirror-imaged with respect to the inner wall of the mounting bin 5, the outer surfaces of the plurality of sliding support blocks 505 slide in contact with the inner wall of the slide groove 503, and the facing side surfaces thereof are fixed to the left and right ends of the bearing plate 502, one end of the clamping column 508 is provided with an anti-slip ring, wherein the left end of the anti-slip ring is fixedly connected to the right end of the reset spring 507, the other end of the clamping column 508 is in contact with and penetrates the right side surface of the mounting block 506 and is plugged into the inner wall of the clamping hole 504, and the clamping hole 504 is equidistantly distributed up and down with respect to the outer surface of the mounting frame 501;

[0031] In the present embodiment, the sliding support block 505 is mainly used to slide with the inner wall of the slide groove 503, and the anti-slip block is mainly used to stretch the reset spring 507 and prevent it from detaching from the clamping column 508. The reset spring 507 is mainly used to apply an elastic force to the clamping column 508, so that the clamping column 508 is in close contact with the clamping hole 504, thereby realizing the displacement drive of the sliding support block 505 on the supporting plate 502, thereby achieving the effect of adjusting the height of the supporting plate 502, and meeting the needs of users.

[0032] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The convenient splicing mechanism 4 includes a groove 401, a lower fastening block 402, a convex ring 403 and an upper fastening block 404. The groove 401 is provided on the top surface of the No. 1 cabinet 1. The lower fastening block 402 is fixedly mounted on the left and right ends of the No. 1 cabinet 1, and a mounting hole 405 is provided on its top surface. The convex ring 403 is fixedly mounted on the bottom side surface of the No. 2 cabinet 2. The upper fastening block 404 is fixedly mounted on the left and right end surfaces of the No. 2 cabinet 2, and a mounting column 406 is fixedly mounted on its bottom, and an eccentric column 407 is provided at the bottom of the mounting column 406.

[0033] Specifically, the cross-sectional shape of the groove 401 matches the shape of the convex ring 403, the lower fastening block 402 is arranged correspondingly to the upper fastening block 404, and its top surface is in contact with the bottom surface of the upper fastening block 404, the outer surface of the mounting column 406 is in contact with the inner wall of the mounting hole 405, and the eccentric column 407 rotates eccentrically with the bottom end of the mounting column 406 through the shaft, and its top surface is flush with the bottom surface of the lower fastening block 402;

[0034] In this embodiment, the contact setting between the convex ring 403 and the groove 401 is mainly used to limit the displacement of cabinet No. 2, so that cabinet No. 2 is in contact with cabinet No. 1, and the setting of the mounting hole 405 is mainly used to fit with the mounting column 406. Under the eccentric rotation of the eccentric column 407, the eccentric column 407 is in close contact with the bottom surface of the lower fastening block 402, thereby realizing the fixation between the upper fastening block 404 and the lower fastening block 402, thereby achieving the effect of split splicing between cabinet No. 1 and cabinet No. 2, and meeting the subsequent transportation requirements.

[0035] The working process of the utility model is as follows: when a low-voltage cabinet is used, the low-voltage cabinet is first moved, and an external force is applied to the eccentric column 407 so that it does not contact the bottom surface of the lower fastening block 402. At this time, an upward external force can be applied to the second cabinet body 2, and the second cabinet body 2 drives the mounting column 406 to separate from the mounting hole 405 and the convex ring 403 to separate from the groove 401, thereby realizing the split disassembly of the low-voltage cabinet, which is convenient for the transporter to carry it to the required position. Further, when it is necessary to adjust the height of the load-bearing plate 502, an external force is applied to the clamping column 508 through the anti-slip ring, and then the clamping column 508 gradually separates from the clamping column 508. The hole 504 disengages and stretches the return spring 507 until the column 508 is completely separated from the hole 504. Under the sliding cooperation of the sliding support block 505 and the slide groove 503, the support plate 502 moves along the outer surface of the mounting frame 501. When the column 508 reaches the hole 504 at a suitable position, the applied external force can be removed, and the return spring 507 in the stretched state will gradually shrink and generate an elastic force, which can drive the column 508 to plug into the hole 504, thereby completing the fixation of the sliding support block 505 and the support plate 502, meeting the adjustment needs of the user and facilitating subsequent use.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
