The rotation of the spiral convex pattern 3101 on the control cylinder 31 will control the connection rod 30 to move backward by squeezing the convex ring 3001, so that the two bevel gears D29 are engaged. Therefore, by turning the handle 27, the toothed belt 16 can be controlled to rotate through the transmission functions of the bevel gears D29 and the gear B28 in turn.

[0059] When using the switch cabinet, first, the switch is arranged on the mounting frame 14. Secondly, according to the number of switches, the number of combinations A and B in the mechanical interlocking device is set. According to the position of the switch, the upper and lower positions of combination A in the cabinet 12 are adjusted, and the left and right positions of combination B on combination A are adjusted. The control hand 3 is connected to the paddles of each switch one by one. Finally, according to the actual switching condition of the switch, the bevel gear B702 is adjusted to mesh with the left and right middle bevel gears A701. For example, in the switch, When the paddle is pushed upward to open the switch and pushed downward to close the switch, the extension arm 9 is rotated forward to disengage the clamping shaft 10 from the clamping block 11. At this time, the movable frame 6 can be pushed to move leftward to move the bevel gear B702 to mesh with the bevel gear A701 on the left side. Then, the extension arm 9 is rotated backward to fix the clamping shaft 10 and the clamping block 11 so that the bevel gear B702 can mesh stably with the bevel gear A701. In this way, the control hand 3 can be swung upward when the control shaft 5 rotates forward, and the control hand 3 can be swung downward when the control shaft 5 rotates reversely. After completing all the above work, the layout of the mechanical interlocking device in the switch cabinet is completed.

[0060] The operating principle of the switch cabinet is as follows (assuming that all switches in the switch cabinet are closed upward and opened downward, so the bevel gear B will be adjusted and moved to mesh with the bevel gear A on the right):

[0061] When it is necessary to inspect and repair the equipment and the switch, or when it is necessary to use the switch to disconnect the power supply to the equipment, the key is used to rotate the lock cylinder 22 to unlock the fixation between the lock cylinder 21 and the frame 20. During the rotation of the lock cylinder 22, the control cylinder 31 will push the connecting rod 30 and the bevel gear D29 on it to move backward, so that the bevel gear D29 on it is engaged with the bevel gear D29 on the gear B28; then the handle 27 is turned. During the rotation of the handle 27: ① The shaft 23 rotates synchronously, and the control threaded column 24 rotates and disengages from the lock hole 19, unlocking the cabinet door 13 and the cabinet body 12. 101, and the threaded column 24 will be locked between them, and the spring 25 will be compressed until the threaded column 24 is completely disengaged from the lock hole 19, the cabinet door 13 can be opened, and the spring 25 is restored; ② the handle 27 will rotate through the matching transmission gear B28 between the bevel gear D29, and the gear B28 will rotate through the matching transmission gear A17 between the toothed belt 16, so that all the control shafts 5 will rotate forward synchronously, the control drum 2 will swing the control hand 3 upward, and all the switches will be closed. Therefore, the cabinet door 13 can be opened at this time to repair the switches and the equipment that has been powered off by the switches.

[0062] After the inspection is completed and confirmed to be correct, the cabinet door 13 is closed, and the threaded column 24 will be first pressed by the lock hole 19, then it will be retracted into the hole 101 first, and the spring 25 is compressed. At the same time, the gear B28 is moved to pass through the groove 1801 and engage with the toothed belt 16. At this time, the handle 27 is reversed to control the threaded column 24 to rotate into the lock hole 19, lock the cabinet door 13 and the cabinet body 12, and drive the control shaft 5 to reverse, so that the control hand 3 swings downward, thereby opening the switch, and then use the key to reverse the lock core 22, so that the lock cylinder 21 cannot rotate, and the spring between the connecting rod 30 and the mounting ring 26 resets the connecting rod 30, so that the two bevel gears D29 are disengaged, so that all the transmission components of the switch cabinet are locked and cannot operate, and the switch paddle is connected to the control hand 3, so that the switch cabinet can lock the switch and realize safe control of the switch.

[0063] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
