The invention discloses a locking device and a method of using the locking device. The locking device comprises an operation panel which is used for receiving manual operation so as to control electrical equipment in the locking device; a cover plate which is used for opening or closing the locking device; a locking switch which comprises a limiting piece, and the limiting piece reciprocates undermanual operation so as to switch on or switch off a power supply of the electrical equipment; and a locking disc which is arranged on one side, close to the electrical equipment, of the operation panel and comprises a clamping part which is movably clamped with the limiting piece, wherein the reciprocating motion of the limiting piece locks or releases the movable clamping, and when the movable clamping is released, the locking disc is used for rotating under manual operation so as to open or close the cover plate. By means of the locking device, electrical equipment can be protected, and possible misoperation of operators is effectively avoided.
Description
technical field [0001] The present invention relates generally to the field of latching switches. More specifically, the present invention relates to a latch and method of using a latch. Background technique [0002] At present, electrical equipment is more and more used in dangerous environments prone to explosion such as underground mines. Due to the particularity of the underground working environment, it is required to first cut off the power of the electrical equipment before operating it. In this way, on the one hand, the personal safety of the operator is protected, and on the other hand, it can also prevent the occurrence of explosion accidents caused by live operation. At present, electrical equipment in mines usually has no protection device, or although there is a protection device, it does not have a locking function. Therefore, such a protection device is easy to be opened, thereby causing non-professionals to open the protection device without authorization ...
