Description

Lock

Technical Field

The invention belongs to the field of mechanical locks and/or intelligent locks, and particularly relates to a high-density capacity hidden unlocking permission key, a lock with high density capacity, high anti-theft performance and high applicability and an emergency lock for providing more safety for an intelligent lock.

Background

The known mechanical locks on application objects are used for ensuring safety after people decorate houses or change renters or after keys are lost or after motor vehicles change owners, so that the owners of the locks need to change the locks again, and the owners are high in cost and inconvenient to use; to solve this key, the disclosed methods are: the known blade lock can only be provided with a marble with the maximum diameter smaller than 2 mm at one position at the innermost end of the key hole to be contacted with round strip marbles with the same external diameter as the low-density capacity, and can only be provided with different unlocking authority keys at one end position on a flat key with the thickness smaller than 2 mm by a unique method of setting a notch or not setting a notch, and the known authority keys are all non-hidden unlocking keys. The known lock and the known rights key have the following defects: ① . The known lock can only be a low-density capacity low-safety lock with a lock core, which is poor in technical unlocking prevention and anti-damage unlocking prevention, and a non-idle lock with a lock core, but not a high-density capacity high-theft-prevention lock without a lock core, an idle lock, a non-spring lock or a hidden lock; ② . Only round marble with the same outer diameter as that of unlocking by using a low-density non-technology can be used for controlling the unlocking or unlocking right termination of the permission key, but not round marble with high-density capacity or blade marble with medium-density capacity is used for controlling the unlocking or unlocking right termination of the permission key; ③ . One end of the round strip marble, which is contacted with the key, can only be arranged at the innermost end position of the key hole but not at any position in the key hole, so that a fixed point position for technical unlocking and unlocking damage is provided for technical unlocking people, and the safety of the lock is further reduced; ④ . The round strip marble can only be used for forming a right lock with the blade marble with medium density capacity, and the round strip marble does not form a lock with the wafer marble with high density capacity; ⑤ . The right key can only be configured into a right key by using a low-density flat key with the thickness of about 2 mm, but not a round key with high density, so that the different right unlocking keys have little distinction, namely only can be distinguished on a key port, and therefore, the different unlocking right keys are made into the same unlocking right key only by a copying mode of filling a gap, thereby resulting in extremely low safety; ⑥ . Only a non-hidden unlocking permission key is used, but not a hidden unlocking permission key with a hidden unlocking function for preventing technical unlocking, vandalism unlocking and key duplication, so that the security of the known permission key and the known lock can be only worst; ⑦ . The known lock is used as an emergency lock configuration on the intelligent lock, so that the safety of the high-safety intelligent lock is reduced to be a lock with poor safety, and the market of the intelligent lock is limited; ⑧ . The known lock has a narrow application range and cannot be used for application objects with high safety requirements, such as motor vehicle locks or bank locks; ⑨ . The round bar marble which controls the unlocking of the right key or the termination of the unlocking right can only move unidirectionally, and the key with the round bar marble which can move or rotate bidirectionally and has the round surface outside diameter is not used because the thickness of the flat key is limited, so that a convenient condition is provided for technical unlocking.
