Abstract

An electronic lock comprises an electronic switch, an electromagnetic winding and a shifting block which are arranged on a lock body. The electronic lock is characterized in that two ends of a symmetrical through hole of the lock body are respectively provided with a left end key inserting hole rotation fixing piece and a right end key inserting hole rotation fixing piece; the shifting block is arranged in a middle gap of a tubular cavity; the rod side of a plectrum penetrates the left rotation fixing piece and is inserted into a reciprocating bayonet lock; the rectangular side of the plectrum penetrates through the shifting block and is inserted into the right rotation fixing piece; a projection end of a clutch column is inserted into a round hole guiding trough of the right rotation fixing piece; an offsetting spring is sleeved outside the clutch column; a breach end of the clutch column is inserted into an inner hole of an anti-smash locating part with a damage-preventing spring, and the clutch column and the inner hole of the anti-smash locating part are fixed by a clutch pin; and the anti-smash locating part is spliced and matched with the right end key inserting hole rotation fixing piece. An anti-drilling, anti-wringing and anti-smash clutch device of the electric lock ensures the flexible unlocking and locking, convenient operation, timely replacement and good safety performance of the lock, therefore, even immoderate positive and reverse rotation of 360 degrees due to error operation can not influence the accurate unlocking and locking operation of the door system. The mechanical and electronic integral lock with the size matching with a general lock is used as an intelligent door unlocking executing mechanism, and the safe and accurate unlocking and locking performance is greatly improved.

Description

A kind of electric lock head

Technical field

The present invention relates to the tapered end that mechanical clutch combines with electronics, a kind of as the unblank electric lock head of executing agency of intelligent entrance guard.

Background technology

Existing universal lock head, it is in the majority to unblank in the mechanical billiard mode, because lock core structure is thin, causes anti-drilling function fragility, even the electronic lock of band rack clutch part is arranged on the market, but structure is numerous and diverse, the control program trouble is unfavorable for that the batch process and the row of popularizing are wide.The tapered end of a small amount of electromechanical adopts motor drive mode, differs with universal lock head installation dimension and volume and too many, can not be general and exchange.Particularly be used as the lock of the terminal execution unit that uses in the long-range gate control system, also exist open close the maloperation phenomenon.

Summary of the invention

The purpose of this invention is to provide a kind of electric lock head, conform to the universal lock head size, easy to operate, open and close flexibly, reset in time, and tool is anti-drilling, prevent turning round, prevent pounding function.

A kind of electric lock head, comprise electronic switch, electromagnet coil and shifting block on the tapered end, it is characterized in that lock body symmetry through hole two ends are provided with left and right end key hole rotational fixture respectively, fracture has shifting block in the middle of in the tube chamber, plectrum bar side is passed the left side rotational fixture, insert in the reciprocal bayonet lock, the plectrum rectangular side is passed shifting block, inserts the moving fixture of turning right; The projection end of clutch cylinder inserts the moving fixture circular hole of turning right and guides in the groove, and the clutch cylinder jacket has back-moving spring, and clutch cylinder gap end has the anti-of anti-tamper spring to pound the locating part endoporus in inserting, and by clutch pin both is fixed; The anti-locating part of pounding cooperates with the grafting of right-hand member key hole rotational fixture.

The present invention combines electromagnetic principle with mechanical clutch means, strengthened the machine security performance and the operation accuracy rate of lock, and be added with the Electromagnetic Control function.Be different from traditional gate inhibition's structure, unblank not to be whole automations.External-open, need before shutting soft copy to get unlocking signal elder generation drive magnet coil, arrangement of clutch starts, and then key cylinder is inserted the lockhole rotational lock core, realize unblanking by mechanical part, otherwise, singly just anti-ly during with key pound locating part and dally.As picking lock by force, the anti-locating part of pounding is pounded suffered pressure and is absorbed, dissolves by wherein spring, and lock core has been played protective effect.Key and lock core just can take off key with changeing 360 °, efficiently solve the problem that shifting block resets, and prevent electronic lock open and close lock state not clear and maloperation occurs.This electric lock head anti-drilling, anti-turning round, the anti-arrangement of clutch of pounding guarantees that the switching of lock is flexible, easy to operate, resets in time, safety and correct open and close performance increase substantially.Even if, all can not influence the correct switching manipulation of the access control system of originally locking a door because of the uncontrolled positive and negative rotation of operate miss 360 degree.
