Description

Technical Field

[0001] The utility model relates to the technical field of passive locks, in particular to a passive lock. Background Art

[0002] Passive locks, such as nokelock X2 and passive electronic locks developed by Vanma, are new types of locks that have appeared in recent years. Their main feature is that they do not require power cords or batteries, but are powered by electronic keys. This type of lock has a built-in encryption chip. When the electronic key is inserted, a password check will be performed first, and the lock can only be opened after passing the password check.

[0003] Passive locks are the same as traditional mechanical locks in terms of mechanical transmission, but they have higher security and manageability. They can not only open multiple locks with one key, but also record the time of unlocking and locking, solving the problem of users' management of personnel, equipment, locks, and keys. In addition, passive locks can also be applied to various environments and usage scenarios, such as dormitories, apartments, schools, rental houses, computer rooms, etc.

[0004] Compared with ordinary electronic locks, passive locks have stronger security and management, and are a necessary means to achieve visual management of the lock opening and closing process. At the same time, since they do not require battery power, passive locks are also more environmentally friendly and energy-saving.

[0005] In general, passive locks are a new type of locks with higher security and manageability, suitable for various environments and usage scenarios. With the development of Internet of Things technology, the application prospects of passive locks will be broader.

[0006] The existing passive lock is provided with a rotatable cover on the lock hole. When the lock needs to be unlocked, the cover is rotated to expose the lock hole and the unlocking operation can be performed. In order to prevent the cover from rotating downward to block the lock hole due to its own gravity, one hand is required to hold the cover and the other hand to perform the unlocking operation, which is inconvenient to use.
