[0007] First screw hole adapted to the hand screw is provided on the fixed support piece;

[0008] The above-mentioned insulation seal board is arranged between hand screw and fixed support piece;

[0009] When fixing the above-mentioned insulation seal board, hand screw is screwed into first screw hole.

[0010] The traditional fixing mode can involve screws or nuts which need tools (such as screwdrivers, wrenches, etc.) to be tightened or loosened, and the utility model adopts hand-screws, so that the user can directly rotate the screws without additional tools, the fixing or removal of the insulation sealing plate is completed, the cumbersome process of searching and using tools is avoided, the operation steps are greatly simplified, and the dismounting efficiency is improved.

[0011] Further, the structure further comprises a limiting piece group, and the limiting piece group is used for connecting the cabinet body;

[0012] The limiting piece group comprises two limiting pieces, and the two limiting pieces are symmetrical about the center line of the insulation sealing plate;

[0013] The limiting piece is provided with a limiting groove, and the insulation sealing plate is inserted into the limiting groove.

[0014] The limiting piece group can realize quick positioning of the insulation sealing plate, the time and energy for repeatedly adjusting the insulation sealing plate due to inaccurate position are reduced, and therefore the installation efficiency is improved; meanwhile, the existence of the limiting groove also ensures the stability of the insulation sealing plate after installation, and prevents safety hazards caused by loosening or displacement; when the insulation sealing plate is removed, the user only needs to loosen the hand-screw first, and then take out the insulation sealing plate from the limiting groove; due to the cooperation of the limiting piece group and the hand-screw, the user can easily complete the dismounting task without complex operation or professional tools, the work efficiency is improved, and the operation difficulty is reduced.

[0015] Further, the limiting piece comprises a limiting plate, a guide plate and a connecting plate, the limiting plate and the guide plate are connected through the connecting plate, and the connecting plate is used for connecting the cabinet body;

[0016] A gap is left between the limiting plate and the guide plate, and the gap forms the limiting groove;

[0017] The guide plate extends the upper end surface of the limiting plate;

[0018] When the insulation sealing plate is inserted into the limiting groove, the limiting plate is attached to the front end surface of the insulation sealing plate, and the guide plate is attached to the rear end surface of the insulation sealing plate.

[0020] Further, the structure further comprises a support, and the support is used for connecting the cabinet body.

[0021] The support is arranged below the fixed support and the limiting piece group, and the support is used for contacting the lower end surface of the insulation cover plate.

[0022] The support directly contacts and supports the lower end surface of the insulation cover plate, thereby enhancing the stability of the insulation cover plate in the vertical direction. During operation or maintenance of the DC switch cabinet, the insulation cover plate is not prone to displacement or shaking due to vibration or external force, thereby ensuring the safety and reliability of the DC switch cabinet. When the user installs or dismounts the insulation cover plate, the support provides additional support for the insulation cover plate, thereby making the operation of the user more convenient. The presence of the support relieves the weight burden of the insulation cover plate, thereby enabling the user to more easily insert and extract the insulation cover plate, simplifying the dismounting process, and improving work efficiency.

[0026] The outer bend arc surface of the insulation cover plate is in contact with the inner bend arc surface of the limiting groove, thereby providing more stable support and positioning. When the insulation cover plate is subjected to external force, the insulation cover plate is not prone to shaking or displacement. Since the contact surface is a smooth arc surface, the risk of damage caused by sharp edges or right angles is reduced. Meanwhile, the contact between the arc surfaces also disperses the pressure, thereby avoiding damage caused by local stress concentration. During the dismounting process, the user only needs to gently push or pull the insulation cover plate, and the insulation cover plate can be smoothly moved in the limiting groove, thereby simplifying the dismounting process and improving work efficiency.

[0027] Further, a second screw hole adapted to a hand screw is arranged on the insulation cover plate.

[0028] When the insulation cover plate is fixed, the hand screw is sequentially screwed into the second screw hole and the first screw hole.

[0029] By screwing the hand screw through the second screw hole on the insulating cover plate and the first screw hole on the fixing support, the fixing of the insulating cover plate and the fixing support is realized, and the loosening or falling off of the insulating cover plate caused by external forces such as vibration and impact is prevented; the hand screw can easily complete the installation and disassembly of the insulating cover plate without using additional tools, and the user only needs to simply rotate the hand screw to the appropriate position to realize fixing or releasing. When installing the insulating cover plate, the insulating cover plate is inserted into the limiting groove, and the lower end surface of the insulating cover plate is in contact with the support, at this time the second screw hole is aligned with the first screw hole, and then the hand screw is screwed into the second screw hole and the first screw hole in sequence, completing the installation of the insulating cover plate.
