Abstract

The utility model discloses a safe electromagnetic lock core, which consists of a rotary axis, a shank, an electromagnet ring, a long impede seat of handle and a long link rod of handle. The shank is arranged in the center hole of the electromagnet ring. The utility model is characterized in that the spring is arranged between the concave-convex slot of axis buckle of the left rotary axis of the electromagnet ring and the concave-convex slot of the left buckle of the shank; the positioning lug is arranged on the right end of the electromagnet ring; the large dish and flaking-proof loop are arranged on the positioning lug; the small dish is arranged between the large dish and shank; the right buckle concave-convex slot of the shank is corresponding to the long link rod of handle; the long impede seat of handle and one end of long link rod of handle are buckled mutually. The structure prevents outside magnetic force from interfering unlock, thereby attaining the safe and reliable aim.

Description

A kind of safety electromagnetic lock core

The utility model relates to a kind of safety electromagnetic lock core

Chinese patent 96204194.7 disclosed dual-purpose electronic locks have following shortcoming: used an electromagnet just facing to a big video disc, the back side is facing to outer handle, when electromagnet produces magnetic force, during the big video disc of adhesive, rotate outer handle and can reach the purpose of unblanking, but on the other hand, when magnet about one ten centimeters is put in the outside of handle outside, can produce magnetic force too, the big video disc of adhesive easily, reach the purpose of unblanking, so, this structure does not just have safety and can say.By the lockset that this structure is made, a careless people just can open door at the hand-held magnet of face outdoors.Complex structure and button bar sliding rail are not smooth, and deviation takes place easily, and ineffective phenomenon causes resetting.

The purpose of this utility model is to provide a kind of safe and reliable safety electromagnetic lock core.

For achieving the above object, a kind of safety electromagnetic lock core of the present utility model, by turning cylinder, button bar, the electromagnetism iron ring, pushing deck, the pushing bar that links is constituted, button bar is established in the centre bore that is placed on the electromagnetism iron ring, it is characterized in that: between the left buckle tongue and groove of the axle buckle tongue and groove of the turning cylinder on the electromagnetism iron ring left side and button bar, be provided with spring, on electromagnetism iron ring right-hand member, be provided with locating convex block, big video disc, anti-flake kink is on locating convex block, between big video disc and button bar, also be provided with little video disc, the right jamming button tongue and groove of button bar is with corresponding the pushing bar that links, pushing deck with a pushing end that links bar buckle mutually.

The utility model compared with prior art has following characteristics:

1 electromagnetism iron ring is positive facing to outer handle direction, can avoid extraneous magnetic force to disturb and unblank.

2 when making adhesive propelling more steadily, rationally.

Fig. 1 is the structural representation of the concrete a kind of embodiment of the utility model;

Fig. 2 is the decomposing schematic representation of Fig. 1.

As Fig. 1, of the present utility model a kind of safety electromagnetic lock core shown in Figure 2, by turning cylinder 1, button bar 3, electromagnetism iron ring 4, pushing deck 8, the pushing bar 14 that links is constituted, button bar 3 is established in the centre bore 16 that is placed on electromagnetism iron ring 4, between the left buckle tongue and groove 12 of the axle buckle tongue and groove 11 of the turning cylinder 1 on electromagnetism iron ring 4 left sides and button bar 3, be provided with spring 2, on electromagnetism iron ring 4 right-hand members, be provided with locating convex block 15, big video disc 6, anti-flake 7 kinks are on locating convex block 15, between big video disc 6 and button bar 3, also be provided with saucer sheet 5, the right jamming button tongue and groove 13 of button bar 3 is with corresponding the pushing bar 14 that links, pushing deck 8 with a pushing end that links bar 14 buckle mutually.When the electromagnetism iron ring produced magnetic force, saucer sheet 5 and big video disc 6 were gone through the bottom because of the skeleton post position of suction relation on electromagnetism iron ring 4 and are advanced.Last saucer sheet 5 promotes button bars 3 and presses to spring 2 and force into to turning cylinder, when the male and fomale(M﹠F) of left buckle tongue and groove 12 with after turning cylinder 1 left buckle tongue and groove contacts fully, right jamming button tongue and groove 13 still contacts with pushing bar 14 male and female faces that link, thereby make the moment of torsion on the handle can reach dead bolt, stir outer handle this moment, can drive dead bolt turning cylinder 1, lock is opened.And, after four seconds, the electronic circuit automatic disconnection.The magnetic force of electromagnetism iron ring 4 disappears, and button bar 3 bullet under the effect of spring 2 leaves dead bolt turning cylinder 1, reaches to shut purpose.
