Then, the screw 874 is passed through the positioning plate 871 and the sleeve 873 to be screwed together with the gate body 11. At this time, the mounting block 81 is fixed to the gate body 11, and the limiting block 861 placed in the mounting block 81 can be positioned to prevent the limiting block 861 and the rubber block 866 from moving.

[0019] Working process: When the separation gate device of the high and low voltage distribution cabinet is in use, the gate body 11 is first electrically connected to the high and low voltage distribution cabinet, and then the gate body 11 is fixed on the high and low voltage distribution cabinet. When the high and low voltage distribution cabinet needs to be powered off, the handle 7 is directly pulled, and the handle 7 drives the connecting plate 5 to rotate outside the sliding shaft 4. At the same time, the handle 7 pushes the splint 84 to rotate, and the splint 84 drives the sleeve 83 to rotate outside the rotating shaft 82. At the same time, the splint 84 pushes the rubber block 866 to deform. When the rubber block 866 deforms, the deformation groove 868 deforms. At this time, one side of the rubber block 866 is supported by the snap plate 862. As the handle 7 moves, it gradually leaves the splint 84. At this time, the handle 7 continues to be rotated until the handle 7 and the toggle block 3 are close to each other. When the handle 7 is pushed to one side of the gate body 11, the handle 7 drives the sliding shaft 4 to slide in the toggle block 3 through the connecting plate 5, until the end of the connecting plate 5 with the arc groove contacts the arc-shaped side of the guide block 628. Then continue to push the handle 7, the handle 7 pushes the connecting plate 5 to move, and the connecting plate 5 pushes the guide block 628 to move. At this time, the guide block 628 drives the slider 624 to slide on the outside of the guide column 623 through the connecting block 627. At the same time, the spring 626 is compressed. Under the action of the pressure of the spring 626, the guide block 628 squeezes the connecting plate 5, limits and guides the connecting plate 5 to a certain extent, until the connecting plate 5 is inserted into the fixed shell 611. At this time, the upper and lower sides of the arc-shaped end of the connecting plate 5 are in contact with the The spring piece 616 contacts, and as the connecting plate 5 moves, the spring piece 616 is compressed. At this time, one end of the spring piece 616 set in the sliding groove 614 opened by the fixed shell 611 slides in the sliding groove 614, and the other end of the spring piece 616 will not move under the action of the plug rod 618, preventing the other end of the spring piece 616 from falling off, until the arc groove opened by the connecting plate 5 moves to the protruding side of the spring piece 616. At this time, the protruding position of the spring piece 616 is stuck in the arc groove opened by the connecting plate 5, positioning the connecting plate 5, and then pushing the handle 7 downward. The handle 7 drives the toggle block 3 to move downward through the connecting plate 5 and the fixed shell 611, and the toggle block 3 drives the switch body 2 to rotate downward, realizing the closing of the gate body 11, and the high and low voltage distribution cabinet is powered off. When this high and low voltage distribution cabinet is closed and energized, the handle 7 is pushed upward to reset the switch body 2, and then the handle 7 is pulled forward to remove the connecting plate 5 from the fixed shell 611, and then the handle 7 and the connecting plate 5 are rotated downward to make the handle 7 contact with the clamping plate 84. As the handle 7 is pushed, the clamping plate 84 drives the housing 83 to rotate outside the rotating shaft 82. After the handle 7 is completely inserted between the four clamping plates 84, the four clamping plates 84 clamp the handle 7 under the action of the rubber block 866 to prevent the handle 7 from moving, thereby preventing the toggle block 3 from being fluctuated and preventing the switch body 2 from being accidentally closed. When the elasticity of the rubber block 866 decreases due to aging, the screw 874 is turned to remove the screw 874, and then the positioning plate 871 and the positioning block 872 are removed.At this time, remove the rubber block 866, the engaging plate 862 and the limit block 861 toward the front, then remove the rubber block 866 and replace it with a new rubber block 866, and use the elastic force and friction of the rubber block 866 to prevent the rubber block 866 from falling off the engaging plate 862. Then, install the rubber block 866, the engaging plate 862 and the limit block 861 back into the rotating groove 85 opened by the installation block 81.
