Abstract

The utility model relates to a lock core which comprises an outer shell body and an inner core body which is arranged in the outer shell body, and the inner core body is rotated and matched with the outer shell body. The lower end of the inner core body is linked with a conveying shifting component, the center of which is provided with a movable contact plate which has a return spring. A barrier plate is arranged in the key hole of the inner core body. The barrier plate is provided with a long spring, the lower end of which penetrates out of the inner core body and is contacted with the upper end surfaces of the movable contact plates. The corresponding positions on the side wall of the outer shell body is provided with a plurality of stationary contact plates which correspond to the movable contact plates. Each stationary contact plate is connected with the control connection point of an outer anti-theft circuit arranged, and a mechanical trigger mechanism is formed. The utility model has the superior performance of the mechanical lock and the superior performance of the electronic lock simultaneously. The mechanical structure is simple, the production is convenient, and the universal performance is good. The operating requirement is convenient, the lock core is easy to be popularized and installed in the exiting door lock, and the intelligent degree of the outer anti-theft circuit is high. The function can be adjusted flexibly by the circuit arrangement being altered, and the maintenance is also convenient.

Description

A kind of lock core

Technical field: the utility model relates to the lock core that a kind of theftproof lock is used.

Background technology: general theftproof lock all adopts the Purely mechanical lock core structure, can make structure very complicated for improving theftproof performance, installs and produces inconvenience, locks destroyed difficult discovery.Some theftproof locks adopts IC intelligent electronic lock, the degree of intelligence height, function is many, can when lock is destroyed, report to the police, but the versatility of the special circuit of electronic lock is poor, safeguards inconvenience, and and the structural difference of general door lock big, it is many to install and use requirement, unfavorable popularization.

Summary of the invention: at the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and can connect the mechanical lock core of anti-theft circuit.

The inner core-body that the utility model comprises shell body and is placed in one and is rotatably assorted, the lower end of the inner core-body rotation dialing part that has been connected, rotate the dialing part center and be provided with the movable contact spring of being with back-moving spring, then be equipped with catch in the keyhole of inner core-body, this catch has long spring, the lower end of long spring passes inner core-body and movable contact spring upper surface pressure is touched, be provided with the static contact of some and movable contact spring correspondence in the sidewall relevant position of shell body, the control contact of each static contact and external anti-theft circuit connects and composes the mechanical type trigger mechanism.

The utility model has the premium properties of mechanical lock and electronic lock simultaneously, frame for movement is simple, convenient for production, versatility is good, and instructions for use is easy, promotes being installed in the existing door lock easily, and the degree of intelligence height of external anti-theft circuit, change the circuit setting, can the flexible modulation function, it is also convenient to safeguard.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings: Fig. 1 is the main structure decomposing schematic representation of embodiment;

Fig. 2 is the structural representation of embodiment closed condition;

Fig. 3 is the structural representation of embodiment unlocking condition;

Fig. 4 is the A-A sectional view of Fig. 3;

Fig. 5 is the B-B sectional view of Fig. 3.

Embodiment: as shown in Figure 1, inner core-body 2 places shell body 1 to be rotatably assorted, the lower end of inner core-body 2 has been connected and has rotated dialing part 3, the center of rotating dialing part 3 is provided with the movable contact spring 5 of band back-moving spring 4, then be equipped with catch 6 in the keyhole of inner core-body 2, this catch 6 has long spring 7, and the lower end of long spring 7 passes inner core-body 2 and movable contact spring 5 upper surfaces pressure is touched.Be provided with the static contact 8 of some and movable contact spring 5 correspondences in the sidewall relevant position of shell body 1, the control contact of each static contact 8 and external anti-theft circuit connects and composes the mechanical type trigger mechanism.Existing lock core has cylinder lock, screens lock etc., present embodiment is provided with horizontal annular groove 9 on inner core-body 2 surfaces, 10 of each card articles that cooperate that are placed in one are located at shell body 1 inwall,

controll block

11 and 12 on spring of compression place inner core-body 2 to vertically move cooperation, and card article 10 corresponding matching that this controll block 11 also is provided with a transverse groove 13 and a side constitute the plece-cliped type lock core.

During normal closed condition, as shown in Figure 2, catch 6 covers keyhole, prevents that dust from entering, if foreign matter enters keyhole and also can be ejected simultaneously.Be reset spring 4 jack-up and each static contact 8 of movable contact spring 5 is all contactless, and controll block 11 also is compressed spring 12 jack-up, staggers in card article 10 positions of a transverse groove 13 and a side, and inner core-body 2 is stuck and does not rotate.During use, extremely shown in Figure 5 as Fig. 3, key can move catch 6 and controll block 11 after inserting keyhole inwards, move to horizontal annular groove 9 with inner core-body 2 when being positioned at same plan-position and card article 10 and cooperating at the transverse groove 13 of controll block 11, inner core-body 2 and controll block 11 just can not blocked by card article 10, but normal rotation is unblanked.Catch 6 also presses down movable contact spring 5 by long spring 7, movable contact spring 5 contacts with a static contact 8 like this, makes external anti-theft circuit work, reaches when imposing a condition, make inner core-body 5 surpass also no rotation normal time together with rotating dialing part 3 as unblanking by force, anti-theft circuit can trigger out alarm signal.Inner core-body 2 and rotation dialing part 3, movable contact spring 5 rotate together in normally unblanking, and movable contact spring 5 contacts with other static contact 8 like this, and anti-theft circuit can not trigger, and rotate other mechanism's interlocks of 3 of dialing parts and lock, open door lock.

More convenient in order to produce, generally each static contact 8 can be arranged on mutual insulating on the pedestal 14, then pedestal 14 is connected on the shell body 1, and the quantity of static contact 8 can be provided with according to the control contact of anti-theft circuit.External anti-theft circuit can be located at other position of door lock in the present embodiment, the complexity of anti-theft circuit and functional characteristic can change on request, sound, light or wireless signal for example are set reports to the police, can also be by the intelligent management system networking of interface and building, improve the automation theftproof performance, and the production installation and maintenance makes things convenient for all.
