Abstract

The utility model discloses a digital lock cylinder. By means of a power gaining switch device, when a key is inserted into a lock hole, a system is powered on, a recognition control circuit begins to work to control an electronic locking device to achieve a function of an electronic lock. When the key is pulled out of the key hole, after finishing corresponding operations, the system is powered down. Therefore, compared with a traditional electronic lock, the digital lock cylinder only needs to work with power on at a necessary time, while the digital lock cylinder is powered down at an unnecessary time, thereby greatly reducing power consumption of the electronic lock. In addition, the power supply mode is reasonable, and power can be supplied directly by batteries. The power gaining switch device and the electronic locking device can be small in size and directly installed in the lock cylinder or a lock cavity. Accordingly, a traditional mechanical core cylinder can serve as a lock cylinder element of the digital lock cylinder with no novel design and manufacture required, manufacture cost is greatly reduced, and a structure is small.

Description

A kind of digital lock core

Technical field

The utility model relates to a kind of lockset, the digital lock core in particularly a kind of door lock.

Background technology

Be locked in and play important effect in the daily life work, good lock is the guarantee of people's security of the lives and property, and present lockset on the market mainly can be divided into mechanical structure and electronic lock structure; Wherein mechanical structure is to unblank or close lock through reversing of key; Belong to more common structure, corresponding easy crack, not ideal enough on the theftproof performance; And electronic lock structure mainly is to drive lock core structure through electromagnetic force to realize the switching of locking; Usually principle is comparatively complicated, and reliability is lower, should cut off the power supply easily or other emergency case and make lock construction be stuck in some actions and can not normally use; Form lock-up condition, be not easy to people's normal use.

Be directed to this; A kind of simple for structure, safe ready and service-strong combination padlock have appearred at present on the market; It mainly is made up of structures such as lock body, lock core, lock gall, controller, holder, digital keys, and electricity-getting switch device and electric locking device are installed in lock core, when digital key inserts lock gall; Control module can be connected with digital key through the electricity-getting switch device; And with the encrypted message of digital chip in the digital key and the comparison of the original code information in the memory, whether meet through judging encrypted message, come to realize unblanking or locking through the electric locking device; Wherein, the electric locking device is used for lock gall is braked, and it is following that illegal key state is gone in the blocking machine transplanting of rice, and the electric locking device is between lock core and the lock gall; Make lock gall not rotate, after inserting legal digital key, the electric locking device will withdraw from lock gall, and make lock gall to rotate; And then open lock, and this structure of braking lock gall through the braking lock body, its electric locking device is generally the element of relay and so on, and volume is bigger; Need be installed in the lock body, make that the lock body structure change is bigger, integral body all need design and make again; Increase cost, and power consumption is also bigger, needs directly to connect civil power usually and carry out work; Especially the ejection and reset two of electric locking device in lock body moved, and all needs consumes power, therefore can increase burden for the energy consumption of combination padlock.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides a kind of structure more reasonable, power consumption combination padlock still less.

The utility model solves the technical scheme that its technical problem adopted:

A kind of digital lock core; Comprise plug body; The electric locking device that be provided with lock gall in the plug body, can be conducted with identification control module and power supply; Be provided with the electricity-getting switch device in the lock gall, whether the identification control module can legal through the opener that electricity-getting switch device identification is inserted in the keyhole of lock gall, it is characterized in that: said electric locking device comprise first permanent magnet that is arranged in the plug body and can be with the synergistic magnetic force mechanism of this first permanent magnet, be arranged on the lock gall and can snap in the groove of first permanent magnet; This magnetic force mechanism can be conducted with identification control module and power supply; When legal unblanking, the identification control module can be controlled first permanent magnet through magnetic force mechanism and from groove, withdraw from, thereby unblanks.

Said electricity-getting switch device comprises power taking probe and the sleeve pipe that is nested with each other; Be pressed with spring between power taking probe and the sleeve pipe; Sleeve pipe is placed in the pellet shot from a slingshot hole of lock gall through insulation sleeve, and sound end is provided with the mechanical billiard of roof pressure sleeve pipe afterbody towards keyhole in the said plug body; This mechanical billiard is provided with the lead via hole; The power taking end of popping one's head in is connected with power supply one utmost point, and the other end can link with legal opener, the power taking probe through legal opener, with identification control module and power supply UNICOM formation loop.

Said magnetic force mechanism comprises and is arranged at the electromagnet in the plug body and is arranged at second permanent magnet on the groove floor.

The polarity of one end that can snap in groove of said first permanent magnet is identical with the polarity of the working end of second permanent magnet; And the other end of first permanent magnet is identical with the working end polarity of electromagnet.

The polarity of the polarity of one end that can snap in groove of said first permanent magnet and the working end of second permanent magnet is opposite; And the working end polarity of the other end of first permanent magnet and electromagnet is opposite.

The beneficial effect of the utility model is: the utility model has been realized when key inserts lockhole, making system power on through the electricity-getting switch device, and recognition control circuit is started working; Control electric locking device is accomplished the function of electronic lock, and extracts lockhole at key, system's power down after accomplishing corresponding operating; Therefore compare traditional electronic lock, the utility model only where necessary between in meet the electrician and do, and under unwanted situation; Just outage; Make electronic lock power consumption reduce greatly, power supply mode is more reasonable, can directly adopt powered battery; It is very little that electricity-getting switch device of the utility model and electric locking device can be provided with; And be directly installed in lock core or the lock gall; Therefore need not carry out new design and manufacturing; Just can use the lock core element of traditional mechanical lock core as the utility model, manufacturing cost reduces greatly, and structure is also less.
