Cipher lock panel apparatus

Abstract

A coded lock face device comprises a hand wheel disc and a base. The hand wheel disc comprises a case, a keyboard fixed in the case, a circuit board and a cabin body, wherein, the cavity of the cabin body can be provided with a cell box for holding four AA batteries; the hand wheel disc can also be provided with an information button seat and an LCD display module; the hand wheel disc is assembled to be a whole, then combines with the base into the face device in a clamping manner. The base is provided with a rotary disc and a follower and can drive a lock cylinder mechanism to act under the condition that the code is authorized; a handle body of the hand wheel disc can also be provided with a fingerprint collection and identification module. With the technical proposal, the joint of the hand wheel disc and the base is firm and the separation of the hand wheel disc and the base is rapid; the face device is provided with the LCD information display module, the information button seat and the fingerprint collection and identification module, thereby greatly improving the functions and safety performance of the coded lock.

Description

technical field [0001] The invention relates to a combination lock, and more specifically, to a combination lock for a safe. Background technique [0002] Existing disc-shaped combination lock panels used for safe cabinets usually have two functions, one as a man-machine interface for exchanging information, and the other as a handle for the lock. Since the shape of the disc-shaped handle should conform to ergonomics, its diameter should not be so large that the hand cannot grasp the range of operation, so the internal space is very limited. In the panel that can be used as the handle of the lock, place an ordinary dry battery that is easy to replace, has a large power, and install other modules with strong functions and wide applications on the panel, such as LCD display module, information button seat, and fingerprint collection and identification module. etc., is an important trend in the development of safe electronic combination lock technology.

AI Technical Summary

Problems solved by technology

In this technical solution, since the bin body can only place 2 AAA (No. 7) batteries, the power that can be provided is very small, and the batteries need to be replaced frequently to maintain the normal operation of the combination lock.

In addition, the hook and slot structures used in the front and rear covers are directly pushed in and snapped together, making it difficult to disassemble. To replace the battery, you need to separate the front and rear covers first, and then separate the bin body from the front cover, which brings inconvenience to the battery replacement operation. inconvenient

Because this panel device can only be installed keyboard and LED indicator light, fails to provide the structure that installs LCD display module and information button seat and fingerprint acquisition identification module, single input and output interface and function, make its actual popularization and use be greatly affected the limitations of
