The rotating shaft 10 is welded and fixed to the inner side of one end of the door panel 2. A lock block 3 is installed in the middle of the other end of the door panel 2. A rubber sleeve 4 is installed on the outer side of the lock block 3. A rubber sleeve 4 is installed on one side of the rubber sleeve 4. The cover 5 and the control panel 6 are installed on the upper side of the front end of the door panel 2; the buffer mechanism 11 includes a curved pipe 111, an air vent 112 is opened on the inner side of one end of the curved pipe 111, a piston 114 is slidably connected to the inner side of the other end of the curved pipe 111, and a movable curved rod 113 is fixedly connected to one end of the piston 114; the end of the movable curved rod 113 away from the piston 114 is welded and fixed to the rotating shaft 10 through a movable plate 13, and the end of the curved pipe 111 away from the piston 114 is fixedly connected to the inner wall of the circular hole 9 through a fixed plate 12.

[0027] As a further implementation of this solution, a mounting frame 7 for controlling the electrical installation is installed inside the control cabinet 1, and a plurality of mounting frames 7 are provided, and the mounting frames 7 are parallel to each other. Through the plurality of mounting frames 7 provided above, it is convenient to install the controller;

[0028] As a further implementation of this solution, the door panel 2 is installed inside the door panel installation groove 8, and the edge of the end of the door panel 2 away from the lock block 3 is arc-shaped, which can prevent the door panel 2 from interfering with the control cabinet 1 body when it is opened;

[0029] As a further implementation of the present invention, the rubber sleeve 4 is "O" shaped, the cross section of the rubber cover 5 is "T" shaped, the lock block 3 is installed inside the rubber sleeve 4, and the rubber sleeve 4 and the rubber cover 5 are clamped and connected, which can prevent the lock block 3 from being exposed to the outside and corroded by water vapor in the air, and has a certain protective effect on the lock block 3;

[0030] As a further implementation of the present invention, two circular holes 9 are provided, the upper and lower ends of the rotating shaft 10 are exposed at the upper and lower ends of the door panel 2, the exposed position of the rotating shaft 10 is installed inside the circular hole 9, and the spring 14 and the buffer mechanism 11 are installed inside the circular hole 9, so that the spring 14 and the buffer mechanism 11 can be stably limited;
