Description

A kind of electronic lock with self-locking function

Technical field:

The invention belongs to the electronic lock cylinders in tapered end field of lockset, and in particular to be a kind of electronics with self-locking function Lock.

Background technique:

With being constantly progressive for science and technology, electronic product is more and more absorbed into traditional industries, such as lockset, The more and more products of lockset of electronic chip control appear in household, and current electronic lock cylinder is divided into no key and has key Cooperate two kinds of Radio decoder, no key, which exists, cracks easy defect, and has the lock core of key cooperation Radio decoder to exist Except being unlocked and be latched using electric power, it will appear in the case where failure or power failure and open difficult defect, simultaneously also In the presence of needing to carry out lock operation again after closing the door, cumbersome, lock core can not also realize self-locking, lock after extracting key It is not high enough to have safety.

Summary of the invention:

In view of the defects existing in the prior art, the object of the present invention is to provide one kind can overcome drawbacks described above with self-locking The electronic lock of function.

The technical scheme adopted by the invention to solve the technical problem is that: a kind of electronic lock with self-locking function, key exist It include lock housing, lock core and control circuit board in the electronic lock with self-locking function, the lock core includes lock core shell, blade and leaf Piece tapered end copper lock pin, the lock housing are equipped with sensing hole and lock hole, are equipped with lock housing bullet pin in the sensing hole, lock housing bullet pin The upper surface that head corresponds to blade locking head copper lock pin is arranged, and solenoid valve, the solenoid valve connection one are equipped in the lock hole Solenoid valve contact is equipped with one on lock core shell and locks hole, and solenoid valve contact, which corresponds to, locks hole setting.

The lock housing bullet pin is connected to lock housing bullet guide, the lock housing bullet guide, pressure spring and lock housing bullet by a pressure spring Pin is arranged in a lock housing insulation sleeve, and the electronic lock further includes a contact, and the lower end of circuit board is arranged in the contact, And correspond to lock housing bullet pin upper end.

Wireless receiving module is equipped in the control circuit board.

Electronic lock with self-locking function of the invention, which is used, is arranged the structure of sensing hole and lock hole in lock housing, in sensing hole The sense contact that interior setting key is inserted into, judges whether key is inserted into, then solenoid valve is arranged in lock hole and connects an electromagnetism Valve contact, solenoid valve contact is extended to be snapped onto lock core, realizes the self-locking of lock core, has the advantages that fast implement self-locking.

Specific embodiment:

As shown in Figure 1 to Figure 2, a kind of electronic lock with self-locking function, the electronic lock with self-locking function include lock housing, Lock core and control circuit board 16, the lock core include lock core shell 5, blade 7 and blade locking head copper lock pin 11, and the blade 7 of multi-disc is logical Cross that blade spring 8 is mobilizable to be connected in lock core shell 5, the lock housing 6 is equipped with sensing hole and lock hole, sets in the sensing hole There is lock housing bullet pin, the upper surface that the head of lock housing bullet pin corresponds to blade locking head copper lock pin is arranged, and electricity is equipped in the lock hole Magnet valve, the solenoid valve connect a solenoid valve contact, and one is equipped on lock core shell and locks hole 21, solenoid valve contact 17 corresponds to anti- Lockhole 21 is arranged.The control circuit board 16 is fixedly connected in lock housing 6 by screw 18, the end of the lock core shell 5 It equipped with groove, is caught in for retainer ring 20, and lock core shell 5 is fixed in lock housing 6 with retainer ring 20.5 end of lock core shell also connects It is connected to transmission item 19.

The lock housing bullet pin 14 is connected to lock housing bullet guide 15, the lock housing bullet guide 15, pressure spring by a pressure spring 10 10 and lock housing bullet pin 14 be arranged in a lock housing insulation sleeve 13, the electronic lock further includes a contact 22, and the contact is set It sets in the lower end of circuit board, and corresponds to 14 upper end of lock housing bullet pin.

Wireless receiving module is equipped in the control circuit board.Wireless receiving module is issued for receiving chip in key To code signal.

In the case that system has electricity and control circuit board 16 is intact, key 1 is inserted among lock core shell 5 and completely right (there is space at a moment of code after key 1 and 7 pairs of codes of blade, blade locking head copper lock pin 11 is past under the action of tabletting 9 and pressure spring 10 Inlayed in lock core shell 5) blade locking head copper lock pin 11 and lock housing bullet pin 14 be in discrete state, and wiring board ground wire is in contact 22 Off-state exports high level at contact 22, and the triode in control circuit board 16 is in the conductive state, and the contact of solenoid valve is inserted Enter to lock in hole 21, key 1 cannot be opened due to lock core shell 5 is locked, therefore transmission item 19 cannot be driven to open lock pin in door Lock, therefore cannot unlock.

Before key 1 is not inserted into lock core shell 5 in system situation out of power, blade locking head copper lock pin 11 and lock housing bullet pin 14 Short circuit, lock housing bullet pin 14 → pressure spring, 10 → lock housing bullet guide 15 → by screw 18 are tightened in the short circuit of lock housing 6--- state, at this point, The solder joint 22 and screw 18 of wiring board are in short-circuit condition output low level, and wiring board triode is in by state.Because electric Magnet no current passes through.Therefore at this point, solenoid valve contact 17 is not inserted into locks in hole 21, do not have in the damage of control circuit board 16 or system In the case where electricity, with correctly to the key of code 1 be can by 5 rotary drive of lock core shell to transmission item 19 open door in lock pin Lock.

The design of this electronic lock, which has, prevents any technology open function.In the case that system has electricity, legitimate user opens the door When, if control circuit board 16 works normally, it just can be used after being swiped the card by correct card reading chip 2 and correctly the key of code 1 be inserted into It is opened in lock core shell 5.

Lock core shell 5 is blocked using the blade locking head copper lock pin 11 of mechanical lock itself not to be able to rotate and cannot open, and works as key When in spoon 1 (correctly to code key or skeleton key) insertion lock core shell 5, blade locking head copper lock pin 11 and lock housing bullet pin 14 are certainly Then dynamic separation causes the solder joint 22 of 16 wiring boards to cause 16 ground wire of control circuit board and 6 short circuit of lock housing to export with through screw 18 Low level makes wiring board receive low level, or reversely receives high level, reaches control solenoid valve contact 17 and locks or not anti- Lock.
