Description

Mechanical puzzle door lock alarm

Technical field

The present invention relates to a kind of door lock, specifically a kind of mechanical puzzle door lock alarm.

Background technology

The kind of door lock is a lot, different to the requirement of door lock in each occasion.In some high-end places, privacy mechanism, Office building, hotel are contour etc. can use coded lock, Fingerprint Lock and glass lock to place, and its safety is the highest but price all compares Costliness, the most applicable for ordinary people family and general place；Average family safe-guard door lock typically belongs to mechanical lock, Safety is higher and price comparison cheap, but owing to mechanical lock structure is relatively simple, lock core is exposed, and lawless person is not having Have key, the most do not damage door lock in the case of utilize some special instruments insert lock core, so that it may realize unlock, enter indoor steal Steal, make the property of people incur loss, even can be by personal injury.It is to have people's meeting deliberately by some lamellars or acicular substance again In insertion door lock core, destroy lock core, make door lock not open, bring trouble and loss.

Summary of the invention

The present invention is directed to the exposed problem existing outside of machine door lock core in above-mentioned prior art, it is provided that a kind of people When opening the door, just can be opened the cover plate closing lock core by the numerical ciphers set, lock core can be closed when not opening the door, protection Lock core is without damage, can prevent the mechanical puzzle door lock alarm occurred by lock core theft crime.

The technical problem to be solved in the present invention is adopted the technical scheme that: described mechanical puzzle door lock alarm includes It is fixedly set in the box body of latch position, the transcoding wheel shaft of described box body internal upper part is arranged at intervals with some transcoding wheels, turns It is disposed with 0-9 numeral on code wheel lateral surface, transcoding wheel end face is provided with gear I, in the lower section corresponding with transcoding wheel Position is provided with the position-limited wheel being fixed on spacing wheel shaft, is provided with notch below described position-limited wheel, and position-limited wheel end face is arranged There is gear III, between transcoding wheel and position-limited wheel, be provided with the dialing wheel being fixed on dialing wheel shaft, on described dialing wheel end face Being provided with gear II, described gear III is meshed with gear I and gear II, described box body is respectively arranged with dialing wheel can be made to stretch Go out the dialing window outside box body and transcoding can be made to take turns the tune code window exposed in box body, in box body, being provided with depression bar, described Depression bar one end is movably fixed on box body, and the other end is supported on stretching spring, is connected with transcoding wheel shaft two ends in the middle of depression bar, institute Being provided with guide-rail plate in stating box body, described guide rail is provided with under external force can be described relative to producing the telescopic block moved Be provided with corresponding with notch in telescopic block and the projection through notch can be synchronized, described telescopic block relative movement can make cover plate to Lower slider, makes lock core expose, upwardly baffle plate, makes cover plate upward sliding and makes hook sleeve at peg, locking cover plate Sealed lock Core.

The driving structure that described telescopic block relative movement can make cover plate slide up and down can include various ways, and the present invention is excellent Selecting following structure: at guide-rail plate two ends, position is provided with peg, on the cover board end is provided with hook, at cover plate lower end and box Connecting between body and have return spring, when described cover plate rises closing lock core, the hook sleeve of described cover plate upper end is on peg and hangs Hook contacts with telescopic block two ends.Be provided with guide plate inside described cover plate, outside cover plate arrange with box body shape all-in-one-piece Panel.

The operation principle of the present invention: first lift depression bar, makes the gear I on transcoding wheel separate with the gear II on dialing wheel, Take turns by adjusting code window to stir five transcodings respectively with hands again, after the password (such as 54123) determined, then put down depression bar, then Box body is fitted in door body, remembers password.When door body opened by needs, first in dialing window, stir five respectively with hands and pull out Number wheel, makes dialing wheel drive transcoding wheel to rotate, stops stirring dialing when the cipher word that the numeral on transcoding wheel is exactly corresponding Wheel, the notch on five position-limited wheels that now gear II coordinates with gear III the most vertically downward, is rotated further by sending out wheel, passes through straight-tooth Wheel coordinates with the spur rack in telescopic block, drives left and right telescopic block to synchronize respectively through notch and to the left and moves right, makes left and right The hook being enclosed within peg is ejected and separates with peg by telescopic block, depart from peg cover plate in return spring effect to downslide Dynamic, make lock core expose, it is achieved mortise lock opens the door；When not opening the door, with hands upwardly baffle plate, make cover plate upward sliding, cover closure During lock core, the hook on cover plate is just enclosed within peg under its inclined plane effect and is locked by cover plate, now in telescopic block Projection deviation notch, it is not known that the people of password, no matter how you rotate and send out wheel, all without make position-limited wheel turn to whole notch with Projection alignment in telescopic block, only knows the people of password, when dialing wheel rotates, position-limited wheel just can be made to turn to whole notch Aliging with the projection in telescopic block, telescopic block just can to the left and move right.

The mechanical door lock alarm of the lock core closed of employing band password of the present invention, compact conformation, switch gate operates Convenient, price comparison is cheap, and safety reliability is high, can effectively prevent the lawless person cannot be with special under not knowing password Instrument inserts lock core unblock entrance indoor and steals.Lock core the most also can be protected to be not readily susceptible to damage.
