Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Please refer to fig. 1-4: the embedded linkage lock comprises a lock mounting plate 1, a lock tongue 2, a lock linkage mechanism 3 and a lock cylinder 4, wherein the lock cylinder 4 is provided with a lock cylinder shifting fork 41 which is linked with the lock linkage mechanism 3, the lock tongue 2, the lock linkage mechanism 3 and the lock cylinder 4 are mounted on the lock mounting plate 1, and a cover plate 11 is further arranged on the lock mounting plate 1;

the lockset mounting plate 1 is also provided with a lockset control module 5 and an electromagnetic switch 6, wherein the lockset control module 5 comprises a micro-control processor 51, a temperature sensor 52, a vibration sensor 53 and an interface module 54; the micro-control processor 51 is respectively connected with the temperature sensor 52, the vibration sensor 53 and the interface module 54, the electromagnetic switch 6 is provided with the interface module 54 which is connected with the lock control module 5 by a cable, the electromagnetic switch 6 is provided with a telescopic armature 61, the armature 61 is connected with an electromagnetic locking block 62 which can stretch with the armature 61, and the electromagnetic locking block 62 for locking the lock cylinder shifting fork 41 is arranged on one side of the lock cylinder shifting fork 41.
