[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Low-voltage switchgear is an indispensable and important component of modern power systems. To reduce the complexity of the assembly process, shorten installation time, and lower labor costs, and because existing low-voltage switchgear often consists of several panels fixed together with screws, a new approach is needed to simplify the assembly process and shorten assembly time. Figure 1 - Figure 6 As shown, a low-voltage switchgear that is easy to assemble is provided, which consists of a base 1 and a cabinet 2 set on top of the base 1. The cabinet 2 is a modular design.

[0028] To avoid the situation where the assembly operation of existing low-voltage switchgear is relatively complicated, which leads to time and labor costs and reduces the overall work efficiency, the cabinet 2 includes side plates 21 and cabinet doors 22 respectively set on the top two sides of the base 1, vertical plates 23 hinged at both ends of the side plates 21, and the cabinet door 22 is movably hinged to one of the vertical plates 23. The cabinet door 22 is provided with a switch lock and is detachably connected to one side of the other vertical plate 23. A top plate 24 is set on the top of the side plates 21. A strip slot 1 is opened at both ends of the top of the base 1. A strip insert 25 matching the strip slot 1 is fixed at the bottom of the two vertical plates 23. A strip slot 2 is opened on one side of the top of the base 1. A strip insert 26 matching the strip slot 2 is fixed at the bottom of the side plate 21.

[0029] During assembly, the two vertical plates 23 are rotated to be perpendicular to the side plate 21, and the cabinet door 22 is parallel to the side plate 21. The side plate 21, the cabinet door 22 and the two vertical plates 23 form the main body of the switch cabinet. Finally, the top plate 24 is placed between the two vertical plates 23 to form a complete switch cabinet body 2.

[0030] To make assembly operations more convenient and reduce the complexity of the assembly process, such as Figure 4 - Figure 6 As shown, a clamping assembly 3 is provided at the bottom of the top plate 24 for fixing the two vertical plates 23 and the side plates 21 together to the base 1. Specifically, the clamping assembly 3 includes movable vertical rods 31 fixedly disposed at the four corners of the bottom of the top plate 24, positioning blocks 32 disposed at the top of the movable vertical rods 31 and fixed to the top plate 24, the top of the movable vertical rods 31 being T-shaped and movably inserted into the positioning blocks 32, and support seats 33 respectively disposed at the bottom of the four movable vertical rods 31 and fixed to the base 1. The movable insert 34 is slidably provided, and the movable vertical rod 31 and the movable insert 34 are provided with matching inclined surfaces on one side. A limiting groove 35 matching the movable insert 34 is provided on one side of the bottom of the movable vertical rod 31. A return spring 36 fixed to the support base 33 is fixed on one side of the movable insert 34. An L-shaped connecting block 37 is fixed on one side of the four movable inserts 34. A pulling component 38 is provided on the top of the base 1 for synchronously pulling the four movable inserts 34 out of the limiting groove 35.

[0031] When installing the top plate 24, first insert the tops of the four movable vertical rods 31 into the positioning blocks 32 respectively. Then, align the top plate 24 with the tops of the two vertical plates 23 and the side plate 21. Insert the bottom of the movable vertical rods 31 into the support base 33. The movable vertical rods 31 move downwards, pushing the movable blocks 34 to one side. The movable blocks 34 compress the return spring 36, causing the return spring 36 to undergo elastic deformation and be compressed. The movable vertical rods 31 move downwards so that the limiting slot 35 matches the movable blocks 34. The return spring 36 restores its elastic deformation and pushes the movable blocks 34 to move. The movable blocks 34 enter the limiting slot 35, locking the movable vertical rods 31 onto the support base 33.

[0032] Furthermore, the pulling component 38 includes connecting rods 381 disposed at both ends of the top of the base 1, and connecting crossbars 382 respectively fixedly disposed at both ends of the bottom of the two connecting rods 381. One end of the connecting crossbar 382 is slidably provided with a support frame 383 fixed to the base 1. The bottom of the four L-shaped connecting blocks 37 is respectively fixedly provided with rack 1 387. The bottom of rack 1 387 is meshed with a transmission gear 384. A support frame 385 fixed to the base 1 is rotatably disposed on the transmission gear 384. One side of the transmission gear 384 is meshed with rack 2 386 which is perpendicular to rack 1 387, and the top of rack 2 386 is fixedly connected to the other end of the connecting crossbar 382.

[0033] When the low-voltage switchgear needs to be disassembled, pull both connecting rods 381 upwards simultaneously. The two ends of the connecting rods 381 drive the connecting crossbars 382 upwards. The connecting crossbars 382 drive the rack 386 at one end upwards. The rack 386 drives the transmission gear 384 on one side to rotate. The transmission gear 384 drives the rack 387 on one side to move. The rack 387 drives the L-shaped connecting block 37 at the top to move. The L-shaped connecting block 37 drives the movable insert block 34 on one side to move. The movable insert block 34 separates from the limit slot 35, so that the movable vertical rod 31 is not locked. Then the top plate 24 can be pulled upwards to disassemble the cabinet 2.
