Hand wheel coded lock with rotating hand feeling

Abstract

The invention provides a brand-new electronic coded lock technical scheme and discloses a hand wheel coded lock with rotating hand feeling. The traditional design regular tendency that passwords are input by watching a device is reversed, passwords are input by changing of the rotating amount and the direction of a hand wheel formed by an incremental encoder, scale indications are not arranged on the hand wheel, a rotating hand feeling mechanism is arranged, rotating hand feeling is used for replacing visual sense for distinguishing, the rotating hand feeling can only be sensed by an operator himself, the safety of the coded lock is fundamentally guaranteed, and the safety performance of the coded lock is improved. The hand wheel coded lock has no keys and no screens, password input operation through the double-direction rotating hand wheel is continuous and smooth, the requirement for using by the blind can be met, the structure is simplified, and dust and water are conveniently prevented. The hand wheel coded lock has wide application prospect in the fields such as safe box cabinet locks, automobile locks, electric vehicle locks, hotel locks, anti-theft door locks, national defense and prevention of thievery of confidentiality facilities.

Description

technical field [0001] The invention relates to the field of anti-theft, in particular to an electronic combination lock. Background technique [0002] At present, combination locks are mainly divided into two types: mechanical and electronic. Mechanical combination locks are more advanced with dial-type combination locks. The process of inputting passwords is similar to operating an old-fashioned dial telephone. Rotate the multi-piece ring-shaped combination disk to the predetermined position, and then turn the knob counterclockwise to open the lock bolt to realize unlocking. The mechanical combination lock has the characteristics of simple structure and convenient operation. However, most of them have insufficient password digits or key quantity; only one password can be preset and it is not easy to change, and the password scale of the dial is also easy to be watched or peeped during operation. Restricted use. [0003] Electronic combination locks can overcome the above...

AI Technical Summary

Problems solved by technology

However, most of them have insufficient password digits or key quantity; only one password can be preset and it is not easy to change, and the password scale of the dial is also easy to be watched or peeped during operation. limited use

[0003] Electronic combination locks can overcome the above-mentioned deficiencies of mechanical combination locks, but there are generally problems of complex structure, high cost, and poor dustproof and waterproof performance, especially when the combination lock with a clear keyboard is operated, it is easy to be watched or peeped to cause leakage; The existence of the keyboard surface will leave traces of use and cause leakage

[0004] CN1605702 The device for password input and password recognition of turntable combination locks proposes a solution, which converts the mechanical rotation angle and direction of the turntable into electrical information to replace the password input by the clear code keyboard, but the disadvantage is that the password information still needs to be displayed, and the password information display At the same time, it may also be peeped by others and cause leakage
