Abstract

The invention relates to the technical field of intelligence, in particular to an intelligent door lock handle clutch with a fireproof function. The clutch comprises a handle adapter assembly, a handle clutch assembly and a driving device; the handle adapter assembly is composed of an outer handle square shaft, a handle adapter shaft, a handle adapter sleeve and a check ring, the handle clutch assembly is composed of an inner handle, a large square shaft, a small square shaft, a square head adjusting screw, a fireproof linkage piece, a driving spring and a pushing spirng; through the handle adapter assembly, the door opening action of the outer handle is connected to the handle clutch in a door, the handle adapter shaft is of a blind hole structure, after locking, the handle outside the door idles, and the defect that an existing outer clutch and a lock body bolt moving shaft hole are exposed is overcome; the defects of safety and reliability existing in an existing intelligent lock external clutch can be effectively overcome, the problem that a clutch and an electronic device fail due to overtemperature, and unlocking cannot be achieved is solved, the structure is ingenious, practicability and reliability are achieved, and the safety and the reliability of the intelligent lock are improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent locks, and relates to an intelligent lock clutch mechanism, in particular to an intelligent door lock handle clutch with a fire prevention function. Background technique [0002] A core component of the smart lock is the main control unlocking servo transmission mechanism (commonly known as the clutch). The design technology of this component directly affects the practicability, reliability and safety of the lock. According to the different installation positions of the clutch, an external clutch, There are three clutch schemes: middle clutch and built-in clutch. In the existing technology, due to technical and cost reasons, more than 90% of smart locks use an external panel clutch mechanism or a central clutch mechanism, and only a small number of built-in clutch mechanisms that are technically difficult and costly are used; limited by technology, For smart locks with external and central cl...
