Abstract

The invention relates to an electronic cylinder, which comprises an electronic switch, an electromagnetic coil and a shifting block on a cylinder body, and is characterized in that both ends of symmetric through holes of the lock body are provided with a left key jack rotary fixing part and a right key jack rotary fixing part respectively; an intermediate fracture in a tubular cavity is provided with the shifting block; a rod side of the shifting block passes through the left rotary fixing part and is inserted into a reciprocating bayonet pin; a rectangular side of the shifting block passes through the shifting block and is inserted into the right rotary fixing part; a lug end of a centrifugal cylinder is inserted into a round-hole guiding groove of the right rotary fixing part; an offsetting spring is sleeved outside the centrifugal cylinder; an opening end of the centrifugal cylinder is inserted with an anti-smashing limit part inner hole the inside of which is provided with an anti-damage spring and fastened with the anti-smashing limit part inner hole through a clutch pin; and an anti-smashing limit part is matched with the right key jack rotary fixing part by means of inserting. An anti-drilling, anti-twisting and anti-smashing engaging and disengaging gear of the electronic cylinder guarantees flexible switching of a lock, is convenient to operate and timely to reset, has good safety performance, and can not influence correct switching operation of a gate control system of the lock even the engaging and disengaging gear is immoderately rotated to 360 DEG positively and reversely due to operating error. The electromechanical integrated cylinder which accords with the dimension of a general cylinder is taken as an intelligent gate control unlocking actuator, so that the safety and the correct switching performance are 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 with the mechanical billiard mode, because lock core structure is thin, causes anti-drilling function fragile, 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 producing in batches and penetration and promotion.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 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, middle fracture has shifting block 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 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.Need soft copy to get unlocking signal elder generation DM coil before the outer open and close lock, 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.Like 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.
