After the outer handle shell 4 is removed, the keyhole of the master cylinder 2 on the master cylinder is exposed. When an adaptive key is inserted into a key hole on the main lock cylinder 2 of the main lock head, the action of the main key mechanism enables the main lock cylinder 2 and the actuating piece 3 to form drivable rotary connection and synchronous rotation in the circumferential direction. I.e. the key is turned to rotate the actuating member 3 to unlock the door lock. When no adaptive key is inserted into the key hole on the main lock cylinder 2 of the main lock head, the main lock cylinder 2 and the actuating piece 3 are both rotationally arranged in the main cylinder cavity of the main lock sleeve 1, but the main lock cylinder 2 and the actuating piece 3 are not in transmission connection and cannot be driven mutually.
In the process of adopting an intelligent unlocking mode, the outer handle terminal seat 19 arranged on the outer handle shell 4 and the outer door terminal seat 21 arranged on the main lock cylinder 2 are always kept in a non-relatively-rotatable state, so that the phenomenon of twisting the twist of the electronic connecting wire of other intelligent components arranged in the shell of the inner handle and the information acquisition module arranged in the outer handle shell 4 can be avoided, the use is safe and reliable, and the disassembly and the assembly are convenient.
The intelligent lock has two opening modes of mechanical key opening and electronic driving opening, even if the outer handle shell 4 is damaged, the lock core part can be unlocked only by unlocking with the key, and the intelligent lock has higher anti-theft performance. Meanwhile, the outer handle can be conveniently disassembled and assembled with the lock head part, only the lock head part with relatively low value needs to be made into different specifications, and the outer handle with the same pair of higher value is assembled to realize different specification changes, so that the production, inventory, sale and other costs of the product are greatly reduced.
Fig. 7 shows a state in which a lock head having the external handle attachment structure of the present invention is mounted on a door lock.
