Problems solved by technology

[0002] After long-term use of the power cabinet, the surface of the internal electrical components will have static electricity, and most of them will be connected to the ground wire to eliminate the static electricity on the surface of the electrical components; Or there will be some residual static electricity inside, so that the staff may be shocked by static electricity when they are working, causing some unnecessary accidents and affecting safe work
In the past, the anti-static safety devices used the overall structure and could not be disassembled at will, which would bring inconvenience to the replacement of various parts and be unfavorable for use.
[0003] Reference document: In a detachable anti-static safety device for power cabinets (application number: 201310136421.2, authorized announcement number: CN103208744B), when the door of the electric cabinet is opened, the handle is turned to press down on the camshaft to drive the rod body to rotate, and the spring rotates with the rod body. When turning to a certain angle, one end of the spring suspended in the air is connected to the electrostatic wire on the surface of the electrical device, and the static electricity is introduced into the ground through the spring, the metal connecting plate, and the ground wire. The door and the rod return to the original state under the action of the spring. In this technical solution, the static electricity on the surface of the electrical device is introduced into the metal connecting plate by the spring. Due to the limited diameter of the spring, it cannot be guaranteed that the spring and the electrical device can contact and conduct electricity during actual use. On the other hand, the introduction of static electricity into the ground requires the staff to turn the handle to rotate the rod body. On the one hand, this operation is easily forgotten by the staff, and on the other hand, it increases the workload of the staff and reduces their work efficiency.

Embodiment 2

[0035] Example two, reference image 3 In this embodiment, one side of the slider 8 is fixed with the connecting rope 4 by glue, and one end of the connecting rope 4 is fixed with the rotating rod 3 by glue, and the other side of the slider 8 is fixed with the reset rope by glue. A fixed pulley 18 is arranged in the middle of the, and the fixed pulley 18 is bolted and fixed to the inner wall of the cabinet 15. The fixed pulley 18 is used to change the direction of the reset rope, and one end of the reset rope is fixed with the mass 20 by glue. Further, the mass 20 is slidably connected to the inside of the guide box 19, the guide box 19 is vertically arranged, and the guide box 19 is bolted and fixed to the inner wall of the cabinet 15. The difference from the first embodiment is that during the closing process of the cabinet door 1, the weight of the mass block 20 is used to make the slider 8 and the moving metal connecting plate move to the end away from the fixed metal connec...

Embodiment 3

[0036] Example three, reference Figure 4 In this embodiment, one side of the slider 8 is fixed with the connecting rope 4 by glue, and one end of the connecting rope 4 is fixed with the rotating rod 3 by glue, and the other side of the slider 8 is fixed with the iron block 21 by glue. One side of the block 21 is provided with a magnetic piece 22 which is magnetically attracted to the iron block 21, and the magnetic piece 22 is fixed on the inner wall of the cabinet 15 by glue. The difference from the first and second embodiments is that in the process of closing the cabinet door 1, the magnetic member 22 and the iron block 21 are magnetically attracted to make the slider 8 and the moving metal connecting plate move away from the fixed metal connecting plate 5. Move one end.

Embodiment 4

[0037] Example four, reference Figure 5 In this embodiment, one side of the slider 8 is fixed with the connecting rope 4 by glue, and one end of the connecting rope 4 is fixed with the rotating rod 3 by glue, and one side of the slider 8 is fixed with a second magnet 24 by glue. One side of the two magnets 24 is provided with a first magnet 23, the first magnet 23 and the second magnet 24 magnetically repel each other, and the second magnet 24 is fixed on the inner wall of the cabinet 15 by glue. The difference from Embodiment 1, Embodiment 2 and Embodiment 3 is that in the process of closing the cabinet door 1, the first magnet 23 and the second magnet 24 are magnetically repelled to make the slider 8 and the moving metal connecting plate move away from each other. One end of the fixed metal connecting plate 5 moves.

Abstract

The invention discloses a power cabinet antistatic safety device convenient to dismount which comprises a cabinet body, a cabinet door and a mounting plate. A rotating rod is rotationally connected toone side of the cabinet body; the rotating rod is fixed with the cabinet door; a connecting block is bolted to the interior of the cabinet body; one end of the connecting block is in bolted connection with the mounting plate; a guide rail is horizontally installed at the top end of the cabinet body; a sliding block is slidably connected in the guide rail; an elastic part is connected to the bottom end of the sliding block; a mobile metal connecting plate is arranged on one side of the elastic part; the mobile metal connecting plate is electrically connected to the surface of the electrical device arranged inside the cabinet body; a fixed metal connecting plate is arranged on one side of the mobile metal connecting plate; the fixed metal connecting plate is fixed at one end of the mountingplate; the fixed metal connecting plate is connected to a grounding device; and the grounding device is mounted at the bottom end of the mounting plate. According to the power cabinet antistatic safety device convenient to dismount, static electricity of the surface of the electrical device can be introduced into the ground during opening of the cabinet door by the user, the stability is higher,and the device is more convenient.

Description

Technical field [0001] The invention relates to the technical field of power cabinet safety accessories, and in particular to an anti-static safety device for a power cabinet that is easy to disassemble. Background technique [0002] After the power cabinet is used for a long time, the surface of its internal electrical components will be charged with static electricity, and most of the electrical components will be connected with a ground wire to eliminate the surface static electricity of the electrical components; however, some components have their surface due to their structure or external environmental influences. Or there will be some residual static electricity inside, so that the staff may be shocked by static electricity while working, causing some unnecessary accidents and affecting safe work. In the past, the anti-static safety device adopts an integral structure and cannot be disassembled at will, which brings inconvenience to the replacement of various parts and is ...
