During normal operation, the circuit can be switched on or off manually or automatically. The distribution switch cabinet is generally used in temporary construction sites to control power equipment. To prevent ground pollution and dampness and facilitate the operation of switch, inspection and maintenance by operators, brackets are installed between such switch cabinets and the ground. To improve the firmness of the bracket support, a base plate is also fixed between the bracket and the cement floor;

[0003] Generally, the switch cabinet and the bracket, as well as the bracket and the base plate, are fixed by bolt locking. When disassembling and assembling the switch cabinet, it is necessary to install the switch cabinet on the bracket and install the bracket on the base plate. The disassembly and installation processes are complex and time-consuming. To better manage and control the power, the construction site power equipment needs to be divided into different areas. For newly added areas, additional switch cabinets need to be assembled. However, most of the brackets at the bottom of the switch cabinets cannot be adjusted in shape to install different numbers of switch cabinets, resulting in a large amount of time consumption for reassembling the brackets of the switch cabinets.

Cross beam two 222 is slidably clamped on both sides of the cross beam one 221. The cross beam two 222 is fixedly connected to the corresponding support column 210. A shaft rod 300 is screwed into the support column 210. The bottom end of the shaft rod 300 is detachably screwed to the corresponding diagonal brace 110. A cabinet 400 is detachably fixed between the tops of multiple shaft rods 300. A limit ring 500 for fixing the cabinet 400 is detachably fixed at the top end of the shaft rod 300.

[0026] Specifically, by first fixing the substrate 100 to the ground, then sleeving the U-shaped bracket 200 on the brace 110 of the substrate 100, passing the shaft rod 300 on the U-shaped bracket 200 through the inner bottom surface of the cabinet body 400, rotating the shaft rod 300 so that the bottom of the shaft rod 300 is screwed and inserted into the brace 110, and the top of the shaft rod 300 presses and fixes the cushion block 420 on the cabinet body 400 through the downward movement of the limit ring 500, the cabinet body 400, the U-shaped bracket 200, and the substrate 100 are connected and fixed together by rotating the shaft rod 300, which is convenient for quickly assembling the distribution switchgear cabinet. By rotating the shaft rod 300 in the reverse direction, the bottom of the shaft rod 300 is separated from the brace 110, and the limit ring 500 at the top of the shaft rod 300 is separated from the cushion block 420, so that the substrate 100, the U-shaped bracket 200, and the cabinet body 400 can be disassembled and separated by rotating one component of the shaft rod 300, which is convenient for quickly disassembling the distribution switchgear cabinet. The length of the U-shaped bracket 200 can be adjusted and extended through the telescopic beam 220, which is convenient for the U-shaped bracket 200 to adapt to and install two cabinet bodies 400.

[0027] As Figure 4 shown, in this embodiment, a square tube 111 is fixed on the top surface of the brace 110, and a slot that is movably inserted with the square tube 111 is opened on the bottom surface of the support column 210. The cross-section of the slot is a square frame structure. Through the setting of the slot, the U-shaped bracket 200 can be accurately inserted onto the brace 110 during the preliminary installation, and the support column 210 on the U-shaped bracket 200 is preliminarily fixed to the brace 110.

[0028] As Figure 4 shown, in this embodiment, a threaded hole 112 is opened on the top surface of the brace 110, a threaded column 310 that is screwed and connected with the threaded hole 112 is fixed at the bottom of the shaft rod 300, the threaded column 310 is screwed and connected with the support column 210, the shaft rod 300 penetrates through the support column 210, and by rotating the shaft rod 300, the threaded column 310 is rotated and screwed into the threaded hole 112, so that the shaft rod 300 fixes the support column 210 and the brace 110 together, and further fixes the U-shaped bracket 200 to the substrate 100.

[0029] As Figure 3 shown, in this embodiment, a jack 320 is opened through the top end of the shaft rod 300. The limit ring 500 includes two semi-circular ring blocks 510. An insertion block 520 that is movably inserted with the jack 320 is fixed on the inner side of the semi-circular ring block 510, and a rubber sleeve is sleeved and fixed on the outer side of the insertion block 520.

[0030] In this embodiment, the insertion blocks 520 on the two semi-circular ring blocks 510 are inserted into the insertion holes 320 at the top of the shaft rod 300, so that the two semi-circular ring blocks 510 form a limiting ring 500 sleeved on the top of the shaft rod 300. As the shaft rod 300 rotates and moves downward, the limiting ring 500 presses against the cushion block 420, and the cabinet body 400 is pressed and fixed on the support column 210. The rubber sleeve enables the insertion block 520 to be firmly inserted into the insertion hole 320, preventing the insertion block 520 from detaching from the insertion hole 320 during the rotation of the shaft rod 300, and improving the firmness of the insertion and fixation of the semi-circular ring block 510.

[0031] As Figure 3 shown, in this embodiment, a nut 330 is fixed at the top end of the shaft rod 300. A plurality of groove-shaped holes 410 facilitating the penetration of the shaft rod 300 are formed in the inner bottom surface of the cabinet body 400. A cushion block 420 is fixed on the top surface of the groove-shaped hole 410. The nut 330 facilitates the rotation of the shaft rod 300 by an external wrench. The length of the groove-shaped hole 410 is greater than the diameter of the shaft rod 300, so that the obliquely arranged shaft rod 300 can be inserted into the cabinet body 400 through the groove-shaped hole 410. The top surface of the cushion block 420 is an inclined surface to facilitate the pressing and fixing of the cabinet body 400 by the limiting ring 500 and the cushion block 420.

[0032] During specific implementation, when disassembling the switch cabinet, open the cabinet door, use a wrench to rotate the nut 330 in the reverse direction to screw out the bottom of the shaft rod 300 from the inside of the diagonal brace 110. At the same time, the limiting ring 500 at the top of the shaft rod 300 disengages from the cushion block 420. When all the shaft rods 300 rotate and disengage from the diagonal brace 110, remove the limiting ring 500 at the top of the shaft rod 300, and then remove the cabinet body 400 from the tops of the plurality of shaft rods 300.

[0033] Embodiment 2, on the basis of Embodiment 1, in order to enable two distribution switch cabinets to be adaptively installed on the C-shaped bracket 200.

[0034] As Figure 5 and Figure 6 shown, in this embodiment, a telescopic beam 220 is arranged between the two support columns 210. The telescopic beam 220 includes a cross beam one 221. Two cross beam twos 222 are slidably clamped on both sides of the cross beam one 221. The cross beam two 222 is fixedly connected to the support column 210 at the corresponding position. Blocks are fixed on both sides of the cross beam one 221. A clamping groove 223 for slidably clamping the block is formed on one side of the cross beam two 222, so that the cross beam one 221 and the cross beam two 222 can slide away from each other or close to each other, realizing the elongation or shortening of the overall length of the telescopic beam 220, and the cross beam one 221 and the cross beam two 222 do not separate.

[0035] As Figure 5 and Figure 6As shown, in this embodiment, L-shaped blocks are fixed to the outer sides of the two struts 210. The L-shaped blocks are fixedly connected to the corresponding crossbeams two 222, so that the two crossbeams two 222 are respectively slidably clamped on both sides of the crossbeam one 221, enabling the entire telescopic beam 220 to extend and contract.

[0036] During specific implementation, when it is necessary to install two cabinets 400 on a U-shaped bracket 200, the two substrates 100 are first separately fixed to the ground, and then the struts 210 are moved in opposite directions, so that the crossbeam one 221 and the crossbeam two 222 on the telescopic beam 220 slide and extend to a length capable of supporting the two cabinets 400. Then, the struts 210 are sleeved onto the diagonal braces 110, and then the cabinets 400 are placed on the tops of the multiple struts 210. The telescopic beam 220 supports the bottom surface of the cabinets 400. Similarly, the shaft rods 300 connect and fix the cabinets 400, the U-shaped bracket 200, and the substrates 100 together, realizing the fixation of the two cabinets 400 on the U-shaped bracket 200.
