Electronic coded lock

Abstract

The invention discloses an electronic coded lock. The lock comprises an integrated casing, a Keyboard plate, a lock cylinder arranged in an accommodating cavity of the integrated casing and a motor assembly; a small lock cylinder opening and closing sliding block, a small lock cylinder limiting sliding block, a small lock cylinder limiting cover plate and a control panel are sequentially arranged in the accommodating cavity from bottom to top; the lower end of the lock cylinder is sequentially inserted into the small lock cylinder limiting cover plate, the small lock cylinder limiting sliding block, the small lock cylinder opening and closing sliding block and an inserting hole of the casing from top to bottom; the motor assembly comprises a motor and a motor transmission threaded shaft sleeve located above the small lock cylinder limiting sliding block; a through hole allowing the lock cylinder to penetrate through is formed in the small lock cylinder opening and closing sliding block; a locking block and a bulge block are arranged on the inner wall of the through hole towards the inner side in a bulge manner; a stop block and a clamping groove allowing the locking block to be clamped are formed in the lock cylinder; a reset spring and a sliding block transmission spring are arranged on the small lock cylinder limiting sliding block; and the sliding block transmission spring is clamped on the tooth position of the motor transmission threaded shaft sleeve. The coded lock acts quickly, accurately and sensitively and is high in stability, safety performance and practicability.

Description

technical field [0001] The invention relates to the field of electronic locks, in particular to an electronic combination lock. Background technique [0002] The problem of property and information security has always been a problem that all walks of life attach great importance to, so the application of locks is ubiquitous, but traditional locks need to carry keys with them, which brings a lot of inconvenience, while combination locks are receiving more and more attention because they do not need keys. Loved and used by people. From traditional cabinet code locks to rope-type code locks for computer applications, code locks are rapidly being used in more and more applications, such as lockers, logistics cabinets, safes, etc. [0003] However, due to the unreasonable design of the internal structure of the traditional combination lock, the sensitivity of opening and closing is low, it is prone to failure, it is inconvenient to use, it is not practical, and its safety perfor...
