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

There are many type of door lock, different in requirement of each occasion to door lock.Some high-end places, privacy mechanism, Office building, hotel are contour etc. to use coded lock, Fingerprint Lock and glass lock to place, and safety is very high but price all compares Costliness is then less applicable in ordinary people family and general place；The safe-guard door lock of average family generally belongs to mechanical lock, Safety is higher and price is relatively cheap, but since mechanical lock structure is relatively simple, lock core is exposed, and criminal is not having There is key and do not damage in the case of door lock and be inserted into lock core using some special tools, so that it may realize unlock, get in into pirate Surreptitiously, the property of people is made to incur loss or even can be by personal injury.It is that someone can be deliberately by some sheets or acicular substance again It is inserted into door lock core, destroys lock core, door lock is made not open, brings trouble and loss.

Invention content

The middle for the above-mentioned prior art machine door lock core of the present invention is exposed the problems of outside, provides a kind of people When opening the door, the cover board of closing lock core can could be opened by the numerical ciphers of setting, lock core can be closed when not opening the door, protected Lock core is without damage, can prevent from stealing the mechanical puzzle door lock alarm of crime generation by lock core.

The technical problem to be solved in the present invention is adopted the technical scheme that：The mechanical puzzle door lock alarm includes The box body of latch position is fixedly set in, several transcoding wheels are arranged at intervals on the transcoding wheel shaft of the box body internal upper part, is turned 0-9 numbers are disposed on code wheel lateral surface, transcoding wheel is provided with gear I on end face, with the corresponding lower section of transcoding wheel Position is provided with the position-limited wheel being fixed on limiting wheel shaft, is provided with notch below the position-limited wheel, position-limited wheel is set on end face There is gear III, be provided with the dialing wheel being fixed on dialing wheel shaft between transcoding wheel and position-limited wheel, on the dialing wheel end face Gear II is provided with, the gear II is meshed respectively with gear I and gear III, and dialing can be made by being respectively arranged on the box body The dialing window and can make the tune code window that transcoding wheel exposes in box body that wheel is stretched out outside box body, are provided with compression bar in box body, Described compression bar one end is movably fixed on box body, and the other end is supported in extension spring, compression bar centre and transcoding wheel shaft both ends phase Even, be provided with guide-rail plate in the box body, be provided on the guide rail under external force can the opposite telescopic block for generating movement, It is provided with corresponding with notch in the telescopic block and convex block across notch can be synchronized, the telescopic block relative movement can make lid Plate slide downward, exposes lock core, pushes up baffle, makes cover board upward sliding and makes hook sleeve in hanging rod, locking cover board envelope It is latched core.

The driving structure that the telescopic block relative movement can slide up and down cover board includes various ways, and the present invention is excellent Choosing is with lower structure：At guide-rail plate both ends, relative position is provided with hanging rod, and end is provided with hook on the cover board, in cover board lower end and box Return spring is connected between body, when the cover board rises closing lock core, the hook sleeve of the cover board upper end on hanging rod and is hung Hook is in contact with telescopic block both ends.Guide plate is provided on the inside of the cover board, being formed with box body for being set on the outside of cover board is integrated Panel.

The operation principle of the present invention：Compression bar is first lifted, separates gear I and the gear II on dialing wheel on transcoding wheel, Again with hand by the way that code window is adjusted to stir five transcoding wheels, determining password respectively（Such as 54123）Afterwards, then compression bar is put down, then Box body is fitted in door body, remembers password.When needing to open door body, five are first stirred respectively in dialing window with hand and is pulled out Number wheel, rotates dialing wheel belt turn code wheel, stops when the number on transcoding wheel is exactly corresponding cipher word stirring dialing Wheel, the notch on five position-limited wheels that gear II coordinates with gear III at this time all vertically downward, are rotated further by hair wheel, pass through straight-tooth Wheel coordinates with the spur rack in telescopic block, and left and right telescopic block is driven to synchronize respectively and to the left and is moved right across notch, makes left and right The hook being sleeved on hanging rod is ejected and is detached with hanging rod by telescopic block, and the cover board for being detached from hanging rod is acted in return spring to downslide It is dynamic, expose lock core, realize that mortise lock opens the door；When not opening the door, baffle is pushed up with hand, makes cover board upward sliding, cover closure During lock core, the hook on cover board is just sleeved on hanging rod under being acted in its inclined surface and locks cover board, at this time in telescopic block Convex block deviate notch, it is not known that the people of password, no matter you rotate hair wheel, will not all make position-limited wheel turn to whole notches and Convex block alignment in telescopic block, only knows the people of password, when dialing wheel rotates, just position-limited wheel can be made to turn to whole notches It is aligned with the convex block in telescopic block, telescopic block just can to the left and move right.

It is of the present invention to use the mechanical door lock alarm for closing lock core with password, compact-sized, switch door operation Convenient, price is relatively cheap, and safety reliability is high, can effectively prevent criminal can not be with special in the case where not knowing password Tool insertion lock core unlock, which is got in, is stolen.Also lock core can be protected to be not readily susceptible to damage simultaneously.
