When the first power device 1 is started again and the cover 2 needs to be closed, the cover 2 is opened and closed by driving the rotating block 3 to rotate, and the second power device 4 moves synchronously with the cover 2.
And after the first power equipment 1 can not realize normal work, the second power equipment 4 is started, and the driving end of the second power equipment 4 is not connected with the rotating block 3 any more, so that the cover body 2 can rotate due to the gravity of the cover body, and the opening of the switch cover is realized.
In the present embodiment, the rotating shaft 6 and the rotating block 3 are rotatably connected, i.e. the rotating shaft 6 can rotate along the central axis thereof.
Specifically, in the present embodiment, the rotating block 3 is an H-shaped structure, one end of the upper portion of the rotating block is connected to the active end of the first power device 1, and the other end of the upper portion of the rotating block is rotatably connected to the mounting plate 9; the rotating shaft 6 passes through the lower part of the rotating block 3. The cover body 2 is fixedly connected with the second power equipment 4 through a plate; and a blind hole is formed in one side of the rotating block 3, which is close to the second power equipment 4. Thus, when the second power device 4 is in the initial state, the connecting rod 7 is inserted into the blind hole, and the opening and closing of the cover body 2 are controlled by the first power device 1; when the second power device 4 is started, the connecting rod 7 is drawn out from the blind hole, and the opening of the cover body 2 is realized by starting the second power device 4.
It should be noted that, in this embodiment, the first power device 1 is a motor that realizes forward and reverse rotation, and the second power device 4 is a telescopic cylinder. Therefore, in some embodiments, the connecting rod 7 is not required to be arranged, and the connection or separation between the cover body 2 and the rotating block 3 can be realized by directly extending the driving end of the telescopic cylinder into or out of the blind hole. In some embodiments, the connection hole 8 may also be a through hole.
In order to better use the embodiment, the rotating block 3 is provided with a limiting block 10; the switch cover further includes a rotation space 11 for the stopper 10 to rotate therein.
In the embodiment, the mounting plate 9 is provided with a fixed block 12 which is arranged on one side of the first power equipment 1 close to the second power equipment 4; the fixed block 12 has an upper block and a lower block, and a region between the upper block and the lower block is a rotation space 11 of the limit block 10.
