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 and locking 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
The present invention relates to the delay locking device and the theftproof lock that utilizes this delay locking device of a kind of delay locking method and realization the method, belong to the field of the lock of fixed buildings.
Background technology
Existing lockset, such as door lock, lock for motorcycle, generally formed by lock body, lock core, transmission mechanism, switching device (such as tapered end), lock core is installed in the lock body endoporus, be provided with some pellets at lock core, be provided with spring groove at the lock body endoporus corresponding to the pellet position, transmission mechanism connects lock core and switching device.Raising along with anti-theft technique, use the theftproof lock of electricity, magnetic, sound, light, password to be widely used on door, bicycle, automobile, the safety cabinet etc., as: title " a kind of theftproof lock of energy delayed alarm ", application number CN95235157.9, it can be when any object enters lockhole and unblanks, if can not finish unlocking action within a certain period of time, the electronic delay warning device will send chimes of doom; And for example: title " a kind of warning anti-theft lock ", application number CN02249811.7, the outer end of pellet is near the key switch that delays warning circuit.Unblank such as theft, key inserts time lengthening, or a plurality of key repeatedly inserts and fail to unblank, and all can cause warning.Because the antitheft form mainly with delayed alarm circuit of delaying time occurs, and lockset itself or openable runs into electronic interferences, and anti-theft effect is unsatisfactory, and often easily wrong report.And antitheft for lockset itself, as utilize the lock core anti-theft technique, title " anti-theft lock ", application number CN200910095360.3, be provided with the envelope pearl in the lock housing and compress spring, compress between spring and the pellet and be provided with card bead, the horizontal side face of at least one pellet is provided with work nest, is provided with locking key between core and the lock housing.As joining under the long attack of locking the master-hand, anti-theft effect is also unsatisfactory.And with the simple combination of two technology, though anti-theft effect can improve, also not fully up to expectations.
