Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a button operating mechanism of an explosion-proof electrical control box, comprising a button box body 1, a support plate sleeve 2 is fixedly connected to the outer surface of the button box body 1, a connecting plate 3 is fixedly connected to the outer surface of the support plate sleeve 2, the outer surface of the connecting plate 3 is fixedly connected to the outer surface of the button box body 1 by bolts, the bottom of the support plate sleeve 2 is fixedly connected to the outer surface of the button body 5 by the connecting plate 3, a screw cover 4 is arranged on the top of the support plate sleeve 2, the outer surface of the screw cover 4 is snap-connected with the inner wall of the support plate sleeve 2, a button body 5 is arranged on the bottom of the screw cover 4, and the button body 5 A movable groove 7 is provided on one side, a first slot 8 is provided on the top of the support plate sleeve 2, a second slot 9 is provided on one side of the first slot 8, the inner walls of the first slot 8 and the second slot 9 are both engaged with the outer surface of the block 10, the outer surface of the screw cover 4 is fixedly connected with the block 10, the top of the block 10 is fixedly connected with a handle 11, the bottom of the screw cover 4 is fixedly connected with a spring 12, the bottom of the spring 12 is movably connected to the inner wall of the movable slot 7, a top column 13 is provided on one side of the spring 12, an anti-slip groove 16 is provided on the inner wall of the support plate sleeve 2, and an anti-slip ring 17 is engaged with the inner wall of the anti-slip groove 16.

[0023] In this embodiment, the support plate sleeve 2 is designed to surround the button body 5 to prevent non-related personnel from touching the button body 5. The connecting plate 3 is provided to fix the support plate sleeve 2 on the outer surface of the button box body 1. The screw cover 4 is provided on the top of the support plate sleeve 2 to facilitate pressing the button from the outside of the button body 5 through the screw cover 4. The spring 12 is movably connected to the inner wall of the movable groove 7. The fixed connection will hinder the rotation of the screw cover 4. The position of the spring 12 is on the outside of the limiting groove 15, and its top is connected to the bottom of the screw cover 4, so that the screw cover 4 can be supported on the support plate by the elastic force of the spring 12. The top of the sleeve 2 prevents the screw cover 4 from being too loose. The depth of the first slot 8 at the top of the support plate sleeve 2 is less than the depth of the second slot 9. When the block 10 is located in the first slot 8, the top column 13 at the bottom of the screw cover 4 is just attached to the surface of the button body 5.

[0026] In this embodiment, the limiting sleeve 6 and the limiting column 14 are designed to be engaged with each other to prevent the screw cover 4 from being displaced during the movement. When the screw cover 4 is pressed, the limiting sleeve 6 will move, so the limiting groove 15 is designed to ensure that the limiting sleeve 6 has space to move.

[0027] Working principle:

[0028] like Figure 1-Figure 4 As shown, when the button body 5 needs to be pressed, pinch the handle 11, rotate the screw cover 4 clockwise, rotate it from the inside of the first slot 8 to the second slot 9, and then press it. The spring 12 first extends and then contracts during the rotation. After pressing, the spring 12 automatically rebounds to lift the screw cover 4. At this time, rotate the screw cover 4 again and place the block 10 in the second first slot 8.
