Description
Technical field:
The utility model relates to a kind of theftproof lock.
Background technology:
At present, the mechanical anti-theft lock structure with multidirectional lock function is all complicated, owing to have multidirectional dead bolt, makes and requires great effort very much when opening the door with key.The theftproof lock that the employing handle opens the door is opened door during strong destruction easily because door handle when locking does not dally.
Existing electronic lock has confidentiality preferably, but owing to there is not multidirectional lock function, is only applicable to the Inner door lock such as hotel, restaurant, is not suitable for security door.Existing electronic lock has the following disadvantages: 1, do not have multidirectional lock function, be not suitable for safe-guard door lock; 2, can not be suitable for mechanical lock and electric actuator at the same time or separately; 3, electric actuator adopts electromagnet, and electromagnet its power consumption in the course of the work is bigger.
Summary of the invention:
For solving above defective, the inventor has proposed a kind of simple in structure, good reliability, theftproof lock mechanical lock and electric actuator, that have multidirectional lock function can be set at the same time or separately.It comprises: be located at the main dead bolt in the lock housing, main dead bolt is provided with and bumps the corresponding draw-in groove of tongue snap close; Be provided with main spring between main dead bolt and lock housing; Main dead bolt is provided with clutch plate and clutch plate spring, and clutch plate is provided with dials point, is provided with in the lock housing and group corresponding handle shift fork of point; Be provided with the unlocking mechanism that promotes clutch plate in the lock housing; Main dead bolt is provided with guide pillar, is provided with and the corresponding guide groove of guide pillar in the multidirectional locking bar in the lock housing.Because be provided with multidirectional locking bar in the lock housing, main dead bolt is provided with guide pillar, makes this lock can realize multidirectional lock function, applicable to security door.The structure because main dead bolt employing handle is unblanked, door is handle idle running when locking, also door can not be opened during strong destruction, opens the door with handle, and it is laborsaving to open the door; And it is simple in structure.
In the utility model, unlocking mechanism can be: the push rod and promoting of unblanking that the promotes clutch plate mechanical lock of push rod of unblanking.When unlocking mechanism only adopted mechanical lock and unblanks push rod, it had the function of mechanical universal lock.
In the utility model, unlocking mechanism can be: the push rod and promoting of unblanking that the promotes clutch plate electric actuator of push rod of unblanking.When unlocking mechanism only adopted electric actuator and unblanks push rod, it had the function of multidirectional electronic lock.
In the utility model, unlocking mechanism preferably: the push rod and promoting of unblanking that the promotes clutch plate mechanical lock and the electric actuator of push rod of unblanking.When unlocking mechanism adopted electric actuator, mechanical lock (standby lock core) simultaneously and unblanks push rod, it can be made into and meets the electronic lock that the Ministry of Public Security requires.
In the utility model, described mechanical lock is page or leaf mortice lock or cylinder of spring lock.When adopting the page or leaf mortice lock, it has better anti-technical opening performance.
In the utility model, described electric actuator comprises: the motor that is electrically connected with IC-card circuit, radio-frequency card circuit or fingerprint recognition circuit, and the worm gear tumbler that matches with the electric machine main shaft worm screw, the worm gear tumbler can promote the push rod of unblanking.Electric actuator adopts motor, and its power consumption is less.Adopt the worm gear tumbler to promote to unblank push rod, can prolong the application life of theftproof lock.
In the utility model, be provided with the clutch plate thrust block in the described lock housing.Door is when locking, and clutch plate has the retaining effect under its spring action.
The course of work of electronic lock of the present utility model is as follows: when opening the door, input electronic code signal (IC-card, radio-frequency card or fingerprint), electronic circuit carry out the school sign indicating number check correct after, machine operation also drives the worm gear tumbler, and the worm gear tumbler promotes to unblank push rod, and the push rod of unblanking promotes clutch plate, group point on the clutch plate is pushed into the handle shift fork can be hooked to the position, this moment turning handle, snap close enters the draw-in groove on the main dead bolt, main dead bolt and multidirectional locking bar are just opened.After several seconds, electronic circuit output motor reverse signal resets the worm gear tumbler.At closing time, bump tongue touching doorframe, bump back of tongue and touch snap close, snap close breaks away from the draw-in groove on the main dead bolt, and this moment, main dead bolt ejected under the effect of main spring, drove multidirectional dead bolt with door locked.Clutch plate opens under its spring action, and the rear portion of clutch plate enters the cavity portion of clutch plate thrust block, has the retaining effect.The point of dialling on the clutch plate is in handle position that shift fork can not arrive, and at this moment, rotates or destroys handle and all theftproof lock can't be opened.
The course of work and the electronic lock of multidirectional locking mechanical lock of the present utility model are roughly the same, its difference is: what mechanical lock promoted to unblank push rod is the lock core dialing part, is electric actuator (motor and the worm gear tumbler that matches with the electric machine main shaft worm screw) and electronic lock promotes to unblank push rod.
In the utility model, mechanical lock and electric actuator can be located in the lock housing together, mechanical lock and electric actuator all can promote the push rod of unblanking, and unblank with electric actuator at ordinary times.When not having electricity or not having the IC-card key, unblank with the stand-by machine lock core.To reach the Ministry of Public Security must be equipped with the emergency machine lock core about electronic lock requirement.
