Unlocking mechanical device

Abstract

The invention relates to an unlocking mechanical device, in particular to a device used for controlling and simulating opening of a door by manual labor in a contactless mode. The technical scheme adopted by the unlocking mechanical device is characterized in that a rotary oscillating arm is arranged on a motor shaft; an oscillating end of the rotary oscillating arm is connected with a handle clamp by means of a drag wire; a motor is controlled by cooperation with a relay; and in the way that axial motion of the motor is converted to up-down reciprocating motion, door-opening actions of a hand in the door can be simulated so that the door can be opened inside without a key by a contactless mode or a remote control module when no person exists inside the door. The unlocking mechanical device has following beneficial effects: by replacing a conventional mode of utilizing the key to unlock, the unlocking mechanical device is used for a special period of time in need of a temporary frequent permit allowing any person to go in and out; due to a simple structure, low production cost and a remote unlocking function, safety is improved and a solution for unified management of unlocking is provided; and the unlocking mechanical device is of great promotional value.

Description

technical field [0001] The invention relates to a lock unlocking mechanism, more particularly to a device for simulating manual opening of a door lock through non-contact manipulation. Background technique [0002] With the rapid development of society and more instability in the development process, people pay more attention to safety issues, and the safety of home door locks is usually very important. The existing unlocking methods mainly adopt mechanical key unlocking, fingerprint unlocking, password unlocking, credit card unlocking and mobile phone unlocking. Once the simple mechanical key is lost, it will cause great inconvenience to people; the way of password unlocking will cause the shape of the lock to be affected. Restricting and pressing the same password for a long time will cause the keyboard change password to be easily leaked; swiping the card to unlock the lock has the same security problems as the key.

Problems solved by technology

The existing unlocking methods mainly adopt mechanical key unlocking, fingerprint unlocking, password unlocking, credit card unlocking and mobile phone unlocking. Once the simple mechanical key is lost, it will cause great inconvenience to people; the way of password unlocking will cause the shape of the lock to be affected. Restricted and pressing the same password for a long time will cause the keyboard change password to be easily leaked; swiping the card to unlock the lock has the same security problem as the key

[0003] In addition, in a certain period of time, it is necessary to temporarily and frequently allow irregular people to enter and exit. At this time, the security risks brought about by the usual unlocking method are more obvious.

For example, when a house is being renovated, different types of workers and material suppliers need to enter the site, key management is prone to handover difficulties, and keys are easy to lose and cause property damage. If you can use remote control to open the door on site, you can achieve keyless Orderly management can solve these problems to some extent

[0004] However, the existing non-contact or remote unlocking devices require a substantial modification of the original locks, so the cost and benefit ratio is very prominent
