Description

Technical Field

[0001] The present invention relates to the field of power anti-touch, and specifically to a mechanical lock that can provide real-time feedback on the opening and closing state. Background Art

[0002] A mechanical lock is a device that realizes locking and unlocking functions through a mechanical structure. It is widely used in various occasions that require safety protection. In the power field, mechanical locks are an important safety protection equipment and are widely used in the safety management of substations, power equipment, distribution boxes, and other power facilities. The main function of traditional mechanical locks is to prevent unauthorized personnel from entering the equipment control area without permission, thereby avoiding problems such as damage, theft, or human operation errors of power facilities.

[0003] However, when this invention is actually used, the following problems exist:

[0004] For existing mechanical padlocks or other mechanical locks, it is impossible to know whether the lock itself is in the open or closed state when operating with a key. In the field of power anti-touch, the state of the lock is crucial for the computer key. If the lock itself has no state, when the lock is in the open state, in order to complete the current anti-error operation step, it is necessary to perform the unlocking operation again. At the same time, without the state of the lock, the computer key cannot indirectly know the state of devices such as the network door. When the lock has a state, the computer key can avoid unnecessary repeated operations and indirectly identify the state of devices such as the network door according to the state of the lock itself, improving work efficiency and the rigor of the operation logic. Summary of the Invention
