The installation frame 51 is... For installing circuit switches, a rectangular through hole 54 is provided on the side of the mounting frame 51 away from the waterproof cover 2. The circuit switch is inserted into the rectangular through hole 54. A mounting plate 52 is rotatably mounted on the side of the mounting frame 51 away from the rectangular through hole 54. The cross-section of the mounting plate 52 is inverted "L" shape, which facilitates the engagement of the limit circuit switch. A first spring 53 is fixedly installed between the mounting plate 52 and the mounting frame 51. The first spring 53 plays the role of driving the mounting plate 52 to elastically clamp the circuit switch. A stabilizing unit is provided on the mounting frame 51. A limit unit is provided on the distribution cabinet body 1. A dust collection component 6 and a limit component 7 are provided on the distribution cabinet body 1.

[0022] The stabilizing unit includes a top plate 55. A telescopic rod 56 and a second spring 57 are fixedly installed on the inner bottom wall of the distribution cabinet body 1. The telescopic rod 56 serves to limit and stabilize the second spring 57. The top plate 55 is fixedly installed on the other end of the telescopic rod 56, and the other end of the second spring 57 is fixedly installed on the top plate 55. The second spring 57 is nested on the outer surface of the telescopic rod 56 and serves to elastically reset. Under the elastic force of the second spring 57, the top plate 55 presses the circuit switch, which stabilizes and clamps the circuit switch, thus improving the stability of the circuit switch installation.

[0023] The limiting unit includes limiting blocks 59. Mounting grooves 510 are provided on the inner walls of both sides of the distribution cabinet body 1. Sliding sliders 511 are slidably installed in the two mounting grooves 510. A connecting plate 58 is fixedly installed between the two sliding sliders 511. Limiting blocks 59 are fixedly installed on the side of the connecting plate 58 closest to the limiting blocks 59. Multiple limiting blocks 59 are present. A circuit switch inside a rectangular through hole 54 is installed between two limiting blocks 59, serving to limit and stabilize the circuit switch. A stabilizing rod 512 is slidably installed through the sliding slider 511. The third spring 513 plays a balancing and stabilizing role, increasing the stability of the slider 511 within the mounting groove 510. Both ends of the stabilizing rod 512 are fixedly installed on the inner wall of the mounting groove 510. The third spring 513 is fixedly installed on the slider 511, with the end of the third spring 513 away from the slider 511 fixedly installed on the inner wall of the mounting groove 510. The third spring 513 is nested on the outer surface of the stabilizing rod 512.

Then, press the connecting plate 58 to move the slider 511 along the stabilizing rod 512, simultaneously squeezing the slider 511. Pressing the third spring 513 compresses it, causing the connecting plate 58 to move the limiting block 59 downwards. This pushes the circuit switch, allowing it to slide left and right within the rectangular through hole 54 and between the mounting plate 52 and the top plate 55. Once the switch reaches the desired position, the connecting plate 58 is released. Under the elastic force of the third spring 513, the connecting plate 58 moves the limiting block 59 upwards, thus limiting the circuit switch. This facilitates the installation and removal of the circuit switch, improves the stability of the device, and increases the efficiency of disassembly and maintenance.

The limiting post 72 is slidably installed through the inner wall of the storage slot 71 near the limiting groove 65. An operating plate 73 is fixedly installed at the end of the limiting post 72 away from the limiting groove 65. A shaped spring piece 75 is fixedly installed at the end of the operating plate 73 away from the limiting post 72. The shaped spring piece 75 serves to elastically reset the limiting post 72. A limiting hole 76 is provided on the limiting plate 66. The limiting post 72 is inserted into the limiting hole 76, which serves to limit and stabilize the position of the limiting plate 66 within the limiting groove 65. The end of the shaped spring piece 75 away from the operating plate 73 is slidably installed on the inner wall of the storage slot 71, facilitating... The irregularly shaped spring piece 75 slides on the inner wall of the storage groove 71. A guide rod 74 is slidably installed through the operating plate 73. Both ends of the guide rod 74 are fixedly installed on the inner wall of the storage groove 71. The guide rod 74 serves to guide and stabilize the operating plate 73. When using the device, first pull the operating plate 73, so that the operating plate 73 drives the limiting post 72 out of the limiting hole 76. At the same time, the limiting post 72 retracts from the limiting groove 65 into the storage groove 71. Simultaneously, the operating plate 73 slides on the guide rod 74, and the operating plate 73 squeezes the irregularly shaped spring piece 75, so that the irregularly shaped spring piece 75 is in a compressed state, which makes it easier to remove the limiting plate 66 from the limiting groove 65. This helps to improve the guiding stability of the device, facilitates the installation and disassembly of the dust collection box 61, and facilitates the limiting and stabilizing of the limiting plate 66, which helps to improve the limiting stability of the device.

[0030] The working principle of this invention is as follows: When using the device, first, insert the circuit switch into the rectangular through hole 54, simultaneously placing the circuit switch between the two limiting blocks 59. Then, press the other end of the circuit switch to squeeze the mounting plate 52, causing the mounting plate 52 to rotate on the mounting frame 51. Simultaneously, the mounting plate 52 stretches the first spring 53, placing the first spring 53 in a stretched state. When the circuit switch passes the mounting plate 52, it squeezes the top plate 55, causing the top plate 55 to squeeze the telescopic rod 56 and the second spring 57, placing the telescopic rod 56 and the second spring 57 in a compressed state. Then, press the connecting plate 58, causing the connecting plate 58 to drive the slider 511 to slide on the stabilizing rod 512. Simultaneously, the slider 511 squeezes the third spring 513, placing the third spring 513 in a compressed state. Simultaneously, the connecting plate 58 drives the limiting blocks 59 to move downwards. Then, push the circuit switch, causing it to slide left and right within the rectangular through hole 54, and simultaneously slide between the mounting plate 52 and the top plate 55, moving to the appropriate position. Afterwards, release the connecting plate 58. Simultaneously, under the elastic action of the third spring 513, the connecting plate 58 drives the limiting block 59 upward, thereby limiting the circuit switch. Then, turn off the exhaust fan 63. Next, move the fixing plate 69 to one side on the distribution cabinet body 1. Then, pull the filter plate 62 out of the slide groove 64 for easy cleaning. Finally, pull the operating plate 73 to move the limiting post 72 out of the limiting hole 76. Simultaneously, the operating plate 73 slides on the guide rod 74, and the operating plate 73 squeezes the irregularly shaped spring 75, while the irregularly shaped spring 75 is in a compressed state. After the limiting post 72 is completely retracted into the storage groove 71, the electric telescopic rod 4 is activated, which lifts the power distribution cabinet body 1, and at the same time separates the dust collection box 61 from the power distribution cabinet body 1. Simultaneously, the limiting plate 66 is removed from the limiting groove 65, and then the dust collection box 61 is pulled out from the base 3 to facilitate emptying the dust in the dust collection box 61.
