Problems solved by technology

[0002] At present, traditional anti-theft locks are mostly fingerprint combination locks combined with traditional mechanical emergency locks, or button-type mechanical combination locks combined with traditional mechanical emergency locks. When the unlocking method fails, the lock can only be unlocked by the key of the mechanical emergency lock, which is very inconvenient in practical application; and because the traditional mechanical emergency lock has a key hole, the anti-theft lock has a great potential safety hazard
In addition, although the existing anti-theft locks can also adapt to doors with different opening directions, it is very inconvenient to change the direction, requiring special tools, and the positions of the handle and the bolt need to be adjusted, which is not flexible enough

Abstract

The invention discloses a combined combination lock, which comprises an inner handle assembly, an outer handle assembly and a lock body, wherein: a clutch mechanism arranged on the outer handle assembly and a driving mechanism for driving the clutch mechanism are also included; the lock body includes a lock case, a lock The tongue and the linkage mechanism that drives the lock tongue to move; the outer handle component can selectively drive the linkage mechanism through the clutch mechanism; the inner handle component is connected with the linkage mechanism and can directly drive the linkage mechanism. The beneficial effects of the present invention are: the present invention combines the fingerprint coded lock and the button-type mechanical coded lock as the dual drive of the coded lock, which avoids the potential safety hazards brought by the traditional mechanical lock and improves the security of the coded lock. In addition, the present invention It is also equipped with a handle reversing mechanism, which is flexible to install; the linkage mechanism of the present invention cooperates with the double drive mechanism and the clutch mechanism to form a complete structure, which can well satisfy people's needs for anti-theft locks such as high safety, convenient and quick use, and flexible installation. various needs.

Description

technical field [0001] The invention relates to the technical field of coded locks, in particular to a combined coded lock combining a key-type mechanical code and a fingerprint code. Background technique [0002] At present, traditional anti-theft locks are mostly fingerprint combination locks combined with traditional mechanical emergency locks, or button-type mechanical combination locks combined with traditional mechanical emergency locks. When the unlocking method fails, the lock can only be unlocked by the key of the mechanical emergency lock, which is very inconvenient in practical application; and because the traditional mechanical emergency lock has a key socket, there is a great security risk in the anti-theft lock. In addition, although the existing anti-theft locks can also adapt to doors with different opening directions, it is very inconvenient to change the direction, requiring special tools, and the positions of the handle and the bolt need to be adjusted, wh...
