Abstract

The invention belongs to the technical field of lock core manufacturing, and in particular relates to an electronic anti-theft alarm lock core. The mechanical structure of pure mechanical locks is relatively simple, and it is easy to open with mechanical means. When the lock cylinder is forcibly twisted with a lock picking tool, the structure in the lock cylinder is easily damaged, resulting in the lock being opened, and the anti-theft safety performance is poor. The invention adds an electronic contact and an alarm circuit to the lock cylinder, and the circuit is connected after a foreign object is inserted into the lock hole, and an alarm is given after the preset time is exceeded. The contact is simple mechanical transmission, direct linkage, and reliable structure. The invention greatly improves the safety of the electronic lock, and the overall structure is compact, firm and durable, and has a wide range of applications.

The specific embodiment

The present invention will be described in detail below in conjunction with the specific embodiment.

The present invention is provided with micromotion mechanism, establishes the mechanism that withdraws a garrison, conduction mechanism and theft-proofing control circuit in electronic lock cylinder.

Referring to Fig. 2, micromotion mechanism is arranged on the keyhole inner end of electronic lock cylinder, by pellet shot from a slingshot 2, triggering pellet shot from a slingshot 3, spring 4, collets 14 and trigger point 5 are formed down.Following pellet shot from a slingshot 2 is positioned at center, keyhole inner end, and the top contact is connected with and triggers pellet shot from a slingshot 3, triggers pellet shot from a slingshot 3 tops and is with spring 4 and collets 14.Collets 14 maintain static, and its top noncontact is provided with trigger point 5.

Referring to Fig. 3, establish the mechanism that withdraws a garrison and mainly be meant and establish the contact 8 of withdrawing a garrison, be arranged on the inner end of lock core keyhole, the rear portion of micromotion mechanism, include lead-out wire 9, positioning convex point 10, insulation plastic body 11, high resiliency beryllium-bronze contact 12, establish the contact shell 13 of withdrawing a garrison.High resiliency beryllium-bronze contact 12 is the beryllium-bronze silk, is provided with two, intert to be arranged in the insulation plastic body 11, about each one.Insulation plastic body 11 tops are provided with two positioning convex points 10, the termination, top of high resiliency beryllium-bronze contact 12 is fixed in the positioning convex point 10, the termination, bottom is arranged on the key back of the body rotary motion trace, contact shell 13 is wrapped in outside the termination, 12 lower end, high resiliency beryllium-bronze contact if withdraw a garrison, become ring set shape, inner ring does not seal, and termination, 12 lower end, high resiliency beryllium-bronze contact can directly be touched with the key back of the body.

Referring to Fig. 1, conduction mechanism mainly is meant conductive strips 6 and output port 7.Trigger point 5 all is connected with conductive strips 6 with lead-out wire 9, and conductive strips 6 are connected with output port 7, and output port 7 is connected with theft-proofing control circuit.

Referring to Fig. 4, the single-chip microcomputer model of theft-proofing control circuit is ATmega48, is connected in parallel to power supply, loudspeaker L1, standby loudspeaker L2, doorbell switch K9 and pick-proof K switch 8 on it; Also be connected in parallel to remote control withdraw a garrison K switch 2, tele-alarm K switch 3 and the remote control of K switch 1, remote control of setting up defences and remove alarm switch K4, all control by remote controller.Removing pick-proof K switch 8 in the circuit is closed accidents, and other switches all are openings.

When ringing a doorbell, be equivalent to doorbell switch K9 closed, loudspeaker can be rung according to the doorbell pattern.

Behind the keyhole of key 1 or foreign matter insertion lock core, at first touch the following pellet shot from a slingshot 2 in the micromotion mechanism, make to move on it and promote to trigger pellet shot from a slingshot 3, the spring 4 that triggers on the pellet shot from a slingshot 3 is compressed, the top of triggering pellet shot from a slingshot 3 passes collets 14, with trigger point 5 touchings, by being connected of conductive strips 6 and output port 7, the circuit of micromotion mechanism part is switched on, referring to Fig. 4, being equivalent to fine motion early warning K switch 7 is closed, warning system in the single-chip microcomputer is activated, in about 10 ~ 15 seconds of Preset Time, and the words that lockset is not opened and rotates, the key back of the body does not contact with the electric shock of withdrawing a garrison, and loudspeaker L1 can ring according to alarm mode.When loudspeaker L1 broke down, standby loudspeaker L2 can work on.

When key clockwise rotates, can touch mutually with the right lower quadrant termination of the high resiliency beryllium-bronze contact 12 of establishing the contact 8 of withdrawing a garrison, this moment the right side lead-out wire 9 conductions, be equivalent to the K switch 5 of setting up defences of turning right closed, promptly set up defences in the right side.

When key rotates counterclockwise, can touch mutually with the lower left quarter termination of the high resiliency beryllium-bronze contact 12 of establishing the contact 8 of withdrawing a garrison, this moment the left side lead-out wire 9 conductions, be equivalent to the K switch 6 of turning left to set up defences closed promptly withdraw a garrison in the left side.The function of deploying troops on garrison duty, withdraw a garrison of left and right sides also can be changed mutually.

When picklock was removed door or window with lockset integral body, closed originally pick-proof K switch 8 was disconnected, and warning function is activated, and loudspeaker L1 will ring with alarm mode.
