Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lock body, especially a mechanical lock body with double driving unlocking mode. BACKGROUND

[0002] The lock body is one of the components of the lock, which is used to open or lock the door and window. The lock body can be classified into two categories according to the driving and unlocking mode, namely the pin tumbler lock and the intelligent lock. Each of the two types of lock bodies has advantages and disadvantages. The pin tumbler lock belongs to a mechanical lock. The surface of the lock cylinder is radially distributed with a plurality of holes, and two rows of cylindrical pins are arranged in the holes, so that the lock cylinder cannot be rotated at will when an incorrect key is inserted, thereby ensuring the safety. The pin tumbler lock has been widely used in daily life. With the development of society, the disadvantages of this type of lock gradually become prominent. Since the design of the lock cylinder of the pin tumbler lock is not much different, the mutual opening rate is high, and the key can be configured at will. Therefore, the safety is insufficient during daily use. The other type of intelligent lock is designed by using electronic technology, integrated circuits and a large number of electronic components. The intelligent lock is more intelligent and safer in terms of identification and safety. However, the disadvantage of the intelligent lock is that the mechanical lock is usually provided inside and outside the door. Since the intelligent lock is used by means of a battery, in the case of power failure, a mechanical lock needs to be matched to ensure that the door can be opened, which reduces the safety of the lock body in the case of power failure.
