[0021] In this embodiment, during assembly, the second card slots 15 opened at the bottom of the two side panels 2 are respectively inserted into the inside of the two first card slots 14, and then the fourth card slots 13 opened at the bottom of the two connecting plates 10 are inserted into the inside of the third card slot 12. The two first card slots 14 are distributed on both sides of the diagonal of the bottom plate 1, so that the two connecting plates 10 limit the two side panels 2, so that the two side panels 2 are fixed to the bottom plate 1, and then the four mounting holes 4 on the upper surface of the cover plate 3 are sleeved on the outer surface of the four limiting clamps 5, and then the cover plate 3 is pushed so that the cover plate 3 is embedded in the inner part of the four limiting clamps 5 through the four mounting holes 4. The cover plate 3 squeezes the two connecting plates 10 to prevent the two connecting plates 10 from being separated from the two side plates 2. When the switch power supply housing needs to be opened, the cover plate 3 is pushed toward one end of the openings of the four limit clamps 5. After the cover plate 3 is subjected to force, it slides inside the limit clamps 5 to make the limit clamps 5 located inside the four mounting holes 4. Then the cover plate 3 is lifted upward to inspect and clean the electronic components installed on the upper surface of the base plate 1.

[0024] In this embodiment, the spring 16 pushes one end of the limit push plate 8 to be embedded in the inside of the groove 6, so that the limit push plate 8 provides support force for the cover plate 3 to avoid displacement of the cover plate 3 and the two side plates 2 after being subjected to external force. When the cover plate 3 needs to be removed, the adjusting member 9 is pressed, and the adjusting groove 17 is in the shape of a right-angled triangle. The inclined surface of one end of the adjusting member 9 fits with the inclined inner wall surface of the adjusting groove 17. The adjusting member 9 pushes the adjusting groove 17, so that the limit push plate 8 moves inside the storage shell 7 after being subjected to force, squeezing the spring 16, and the spring 16 absorbs kinetic energy. After releasing the adjusting member 9, the spring 16 pushes the limit push plate 8 to return to its original position, and the adjusting groove 17 pushes the adjusting member 9 to return to its original position, thereby improving the stability of the structure and its impact resistance. A plurality of equidistant strip windows 11 ensure air circulation.

The two first card slots 14 are distributed on both sides of the diagonal of the bottom plate 1, so that the two connecting plates 10 limit the two side panels 2, so that the two side panels 2 are fixed to the bottom plate 1, and then the four mounting holes 4 on the upper surface of the cover plate 3 are sleeved on the outer surface of the four limiting clamps 5, and then the cover plate 3 is pushed to make the cover plate 3 embed into the inside of the four limiting clamps 5 through the four mounting holes 4. The cover plate 3 squeezes the two connecting plates 10 to prevent the two connecting plates 10 from separating from the two side panels 2. When the switch power supply housing needs to be opened, the cover plate 3 is pushed toward one end of the opening of the four limiting clamps 5. After the cover plate 3 is subjected to force, it is in the limit clamps 5. The inner slide makes the limit card 5 located inside the four mounting holes 4, and then the cover plate 3 is lifted upward to inspect and clean the electronic components installed on the upper surface of the bottom plate 1. The spring 16 pushes one end of the limit push plate 8 to be embedded in the groove 6, so that the limit push plate 8 provides support for the cover plate 3 to avoid displacement of the cover plate 3 and the two side plates 2 after being subjected to external force. When the cover plate 3 needs to be removed, the adjusting member 9 is pressed, and the adjusting groove 17 is in the shape of a right-angled triangle. The inclined surface of one end of the adjusting member 9 fits with the inclined inner wall surface of the adjusting groove 17. The adjusting member 9 pushes the adjusting groove 17, so that the limit push plate 8 moves inside the storage shell 7 after being subjected to force, squeezing the spring 16. The spring 16 absorbs kinetic energy. After releasing the adjusting member 9, the spring 16 pushes the limit push plate 8 to return to its original position, and the adjusting groove 17 pushes the adjusting member 9 to return to its original position.
