Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] According to an embodiment of this utility model, an insulation board mounting structure for a low-voltage switchgear is provided. Please refer to [link / reference]. Figures 1 to 5The device includes: a low-voltage switchgear cabinet 1, mounted on an installation reference, the low-voltage switchgear cabinet 1 having an installation space 2 and an installation port 3 communicating with the installation space 2, and electrical components installed in the installation space 2; an insulating plate 5, the insulating plate 5 being disposed at the installation port 3, the insulating plate 5 being used to prevent external personnel from accidentally touching the electrical components in the installation space 2; and at least two mounting components 6, the plurality of mounting components 6 being disposed at intervals along the outer edge of the insulating plate 5, the mounting components 6 being used to install the insulating plate 5 at the installation port 3.

[0027] By adopting the above technical solution and through the design of the installation component 6, it is easy to quickly install the insulation board 5 at the installation port 3. This solves the problems of the screw fixing method, which requires a lot of manual operation, requires disassembling multiple fasteners during replacement or maintenance, is time-consuming and labor-intensive, and requires drilling holes in the cabinet and insulation board, increasing the production process.

[0028] Please refer to Figure 3 and Figure 4 The mounting component 6 includes: a first connecting plate 7, a second connecting plate 8, and a third connecting plate 9; the first connecting plate 7 is connected to one end of the second connecting plate 8, and the other end of the second connecting plate 8 is connected to the third connecting plate 9. Both the first connecting plate 7 and the third connecting plate 9 extend along the width direction of the low-voltage switchgear 1. Figure 1 The direction of the middle arrow A is the width direction of the low-voltage cabinet 1. The first connecting plate 7 and the third connecting plate 9 are both perpendicular to the second connecting plate 8, and the free end of the first connecting plate 7 is opposite to the free end of the third connecting plate 9. The first connecting plate 7 is provided with a first magnetic attraction part 10, and the first connecting plate 7 is fixedly connected to the low-voltage cabinet 1 through the first magnetic attraction part 10. The second connecting plate 8 is provided with a clamping part 11, which is used to clamp the insulating plate 5.

[0029] By adopting the above technical solution, and through the design of the first magnetic suction part 10 and the clamping part 11, the insulating plate 5 can be installed quickly and easily through the magnetic suction installation method during the installation process, saving steps and increasing the installation speed.

[0030] When the mounting component 6 is installed on the low-voltage cabinet 1, the free end of the third connecting plate 9 faces the mounting port 3, and the free end of the first connecting plate 7 faces the inner wall of the mounting space 2.

[0031] Please refer to Figure 3 The second connecting plate 8 is provided with a second magnetic suction part 19. The second connecting plate 8 is installed on the side wall of the mounting port 3 through the second magnetic suction part 19, so that the second connecting plate 8 is relatively fixedly connected to the low-voltage cabinet body 1. The clamping part 11 and the second magnetic suction part 19 are spaced apart along the height direction of the second connecting plate 8.

[0032] By adopting the above technical solution and through the design of the second magnetic attraction part 19, the fixing effect of the insulation board 5 is increased during the installation process of the insulation board 5 by the second magnetic attraction part 19 being magnetically attracted to the low-voltage cabinet 1 again.

[0033] Please refer to Figure 3 The first connecting plate 7 and the second connecting plate 8 are both provided with mounting grooves 12 on the side near the low-voltage cabinet 1; the first magnetic part 10 includes a first magnet, the second magnetic part 19 includes a second magnet, and the first magnet and the second magnet are installed in the corresponding mounting grooves 12; the first connecting plate 7 and the second connecting plate 8 are connected to the low-voltage cabinet 1 through the corresponding first magnet and the second magnet.

[0034] By adopting the above technical solution and through the design of the first and second magnets, the installation method of bolts is replaced in the installation process of the insulation board 5. The insulation board 5 can be installed more quickly through magnetic attraction.

[0035] Please refer to Figure 3 and Figure 4 The clamping part 11 includes: a clamping plate 15, a through groove 14 is provided on the second connecting plate 8, the through groove 14 extends along the length direction of the second connecting plate 8, at least a portion of the clamping plate 15 is movably disposed in the through groove 14 along the extension direction of the through groove 14, the clamping plate 15 is disposed toward the mounting opening 3; the clamping plate 15 abuts against the insulating plate 5.

[0036] By adopting the above technical solution and through the design of the clamping plate 15, it is easy to connect the insulating plate 5 with the first magnetic suction part 10 and the second magnetic suction part 19, which facilitates the later installation on the low-voltage cabinet 1.

[0037] Please refer to Figure 5 The clamping part 11 further includes a sliding member 16, which is movably disposed in the through groove 14 along the extension direction of the through groove 14. The abutment plate 15 is movably disposed in the sliding member 16 along the thickness direction of the second connecting plate 8, so that the abutment plate 15 can be moved by the sliding member 16.

[0038] By adopting the above technical solution and through the design of the sliding member 16, the length of the clamping plate 15 can be adjusted according to the size of the insulating plate 5 during the clamping process of the clamping plate 15. The size requirements of the insulating plate 5 are relatively relaxed and it can be applied to most sizes of insulating plates 5.

[0039] Please refer to Figure 5 The clamping part 11 also includes a spring 17, which is disposed in the through groove 14 and extends along the extension direction of the through groove 14. The two ends of the spring 17 are respectively connected to the slider 16 and the inner wall of the through groove 14 away from the third connecting plate.

[0040] By adopting the above technical solution and through the design of the spring 17, during the process of clamping the insulating plate 5 by the clamping plate 15, the spring 17 pushes the clamping plate 15, so that the clamping plate 15 clamps and fixes the insulating plate 5, eliminating the need to drill holes in the insulating plate 5 in advance and then fix it with bolts, thus simplifying the production process.

[0041] Please refer to Figure 5 The clamping part 11 also includes two blocking plates 18, which are respectively disposed at both ends of the abutment plate 15. Both blocking plates 18 are perpendicular to the abutment plate 15, and the free end of the blocking plate 18 located on the end of the abutment plate 15 away from the through groove 14 is arranged in a direction away from the third connecting plate 9.

[0042] By adopting the above technical solution, the design of the blocking plate 18 prevents the abutting plate 15 from sliding within the sliding member 16 and disengaging from the limit of the sliding member 16.

[0043] Please refer to Figure 5 The abutment plate 15 has a sharp part 13 on the side facing the third connecting plate 9, and the sharp part 13 is used to fix the insulating plate 5.

[0044] By adopting the above technical solution and through the design of the sharp part 13, the stability of the clamping plate 15 in holding the insulating plate 5 is increased.

[0045] Working principle:

[0046] First, move the clamping plate 15 to compress the spring 17, causing the clamping plate 15 to disengage from the third connecting plate 9. Then, place the third connecting plate 9 on the outer edge of the insulating plate 5. Then, release the clamping plate 15. Under the force of the spring 17, the clamping plate 15 presses the insulating plate 5 against the third connecting plate 9. Install the insulating plate 5 sequentially on the outer edge of the insulating plate 5. After installation, attach the first connecting plate 7 and the second connecting plate 8 to the mounting port of the low-voltage cabinet body 1. Under the action of the first magnet and the second magnet, install the insulating plate 5 on the low-voltage cabinet body 1.
