Delay locking method, delay locking device and anti-theft lock

Abstract

The invention relates to a delay locking method, a delay locking device and an anti-theft lock, and belongs to the field of locks. The extension and retraction of a locking contact is controlled by a delay control device and the unlocking and locking of a lock cylinder marble is controlled by the locking contact so as to fulfill the aim of delay locking. The device is characterized in that: when an unlocking guard plate is unlocked or after an unlocking command is triggered, the delay control device drives the locking contact to return and unlock the lock cylinder marble in a locked state through a transmission device, a cylinder of a lock can be unlocked by a key in certain time, namely delay time set by the delay control device; the delay control device drives the locking contact to lock the lock cylinder marble in an unlocked state through the transmission device after the delay time is out; if the previous key is still in the lock at the time, the key can control the unlocking andlocking of the lock, and if the key is inserted again, the key cannot unlock the cylinder; and the delay control device comprises a mechanical delay control device or an electronic delay control device. If the key is unlocked in a theft mode, the time for manufacturing and testing the theft key is extremely short, the lock is difficult to unlock, and the anti-theft effect is obviously enhanced.

Description

technical field [0001] The invention relates to a time-delay locking method, a time-delay locking device for realizing the method, and an anti-theft lock using the time-delay locking device, belonging to the field of locks for fixing buildings. Background technique [0002] Existing locksets, such as door locks and motorcycle locks, are generally composed of a lock body, a lock cylinder, a transmission mechanism, and a switch device (such as a lock head). , the hole in the lock body is provided with a pin slot corresponding to the position of the pin, and the transmission mechanism is connected with the lock cylinder and the switch device. With the improvement of anti-theft technology, anti-theft locks using electricity, magnetism, sound, light, and passwords have been widely used on doors, bicycles, automobiles, safes, etc., such as: the name "An anti-theft lock that can delay alarm" 》, application number CN95235157.9, when any object enters the keyhole for unlocking, if t...

AI Technical Summary

Problems solved by technology

For example, under the long-term attack of a lock matching master, the anti-theft effect is not ideal.

With the simple combination of the two technologies, although the anti-theft effect can be improved, it is still not satisfactory.
