Abstract
The utility model relates to a lock core, particularly a magnetic card lock core, which belongs to the technical field of locksets, and is composed of an inner core, a core casing, an inner core magnetic sheet, a composite magnetic card key, a compression spring, a common spring lock core, etc. The utility model combines advanced magnetic art with the general the prior art of spring lock cores to cut down the mutual unlocking rate of keys of locksets to 1/100000 so as to effectively prevent the larceny cases of unlocking caused by duplicating keys, and is optimized design integration in the present technical field of locksets.
Description
The utility model relates to a kind of lock core, and especially a kind of magnetic card lock core belongs to lock technology field.
Lock core is the maincenter of lockset, the lock core that lockset is used on the present domestic market, basically still generally use the higher padlock of spring type lock core, particularly utilization rate that comparatively falls behind, the spring type lock core has used unalterablely and has reached a nearly century, because it is simple in structure, key reprovision rate height, security performance is low, and the stolen loss that brings to the user is bigger, can not satisfy the requirement of people, cause many inconvenience and produced great potential safety hazard to people's life to lockset safety.
The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of security performance height, composite magnetic cards lock core scientific and reasonable for structure are provided.
In order to achieve the above object, the technical solution that the utility model adopts is: a kind of composite magnetic cards lock core, comprise inner core, the core overcoat, general lock cylinder, composite magnetic cards key and key guide hole, keyhole and swinging plate etc., in-core was provided with three inner core magnetic sheets and three locating holes on the other side in its special character was, be provided with two switching posts and a reference column in the core overcoat, two inner core magnetic sheets near the inner core two ends are corresponding with two switching posts that core puts outward respectively, the inner core magnetic sheet that is positioned at the inner core middle part is corresponding with the reference column that core puts outward, and respectively there is a compression spring inner core magnetic sheet lower end at the upper end of two switching posts and inner core middle part.
Above-described composite magnetic cards lock core, its special character also be the one side of composite magnetic cards key have one group respectively with the corresponding key magnetic sheet in the position of three inner core magnetic sheets, identical with the pole polarity of two switching posts corresponding two groups of inner core magnetic sheets of difference and key magnetic sheet, different with the pole polarity of corresponding inner core magnetic sheet of reference column and key magnetic sheet; The another side of composite magnetic cards key has and the corresponding general pellet shot from a slingshot of general lock cylinder hole.
The utility model compared with the prior art, owing on the basis of prior art lock cylinder, increased the composite magnetic cards effect of magnetic force structure, improved the anti-theft feature of lockset greatly, make the precision of lockset that breakthrough raising arranged, and the mutual opening rate that makes key reduces to 100,000/below, thereby make people's property obtain strong safety guarantee.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model locking-in state.
Fig. 3 is the left view of Fig. 1.
Fig. 4 is the structural representation of composite magnetic cards key magnetic face.
Fig. 5 is the rear elevation of Fig. 4.
As Fig. 1, Fig. 2, shown in Figure 3, composite magnetic cards lock core described in the utility model mainly is made up of inner core 1, core overcoat 2, general lock cylinder 11, composite magnetic cards key 5, key guide hole 13, keyhole 4 and swinging plate 3 etc., be provided with inner core magnetic sheet 7,8,9 and corresponding with it three locating holes 15 in the inner core 1, be provided with in the core overcoat 2 and open and close post 10,12 and reference column 14, inner core magnetic sheet 7,8,9 respectively with open and close post 10, reference column 14, to open and close post 12 corresponding, opens and closes the upper end of post 10,12, respectively there is a compression spring 16 lower end of inner core magnetic sheet 8; As Fig. 1, Fig. 4, shown in Figure 5, the one side of composite magnetic cards key 5 have one group respectively with the corresponding key magnetic sheet 17,18,19 in inner core magnetic sheet 7,8,9 positions, inner core magnetic sheet 7 is identical with the pole polarity of key magnetic sheet 17, inner core magnetic sheet 9 and key magnetic sheet 19, and inner core magnetic sheet 8 is different with the pole polarity of key magnetic sheet 18; The another side of composite magnetic cards key 5 has and general lock cylinder 11 corresponding general pellet shot from a slingshot holes 20.
Under the effect of compression spring 16, open and close post 10,12 and move down, be displaced downwardly in the locating hole 15 and stop, opening and closing company's seam crossing that post 10,12 is in inner core 1 and core overcoat 2 this moment thereby promote inner core magnetic sheet 7,9, play interconnect function, stoped the rotation of inner core 1 simultaneously with core overcoat 2; Meanwhile, under the effect of another compression spring 16, when inner core magnetic sheet 8 rises to and contacts with reference column 14, inner core magnetic sheet 8 just stops to rise, at this moment, inner core magnetic sheet 8 is in the company's seam crossing between inner core 1 and the core overcoat 2, has also stoped the rotation between inner core 1 and the core overcoat; General lock cylinder 11 stops inner core 1 corresponding with rotational structure and magnetic force structure between the core overcoat 2, so just makes lock core be in locking-in state, as shown in Figure 2.
When needs are opened lock, composite magnetic cards key 5 is inserted in the keyhole 4 by key guide hole 13, at this moment, because inner core magnetic sheet 7 is identical with the magnetic of key magnetic sheet 17, inner core magnetic sheet 9 and key magnetic sheet 19, thereby produce mutual repulsive force, under the effect of repulsive force, it is equal with core overcoat 2 connecting lines that the upper surface of inner core magnetic sheet 7,9 rises to inner core 1, and the lower surface that opens and closes post 10,12 simultaneously is also equal with the connecting line of core overcoat 2 with inner core 1; Meanwhile, because inner core magnetic sheet 8 is different with the magnetic of key magnetic sheet 18, produce the power that attracts each other, under the effect of this attraction, inner core magnetic sheet 8 moves down, and will compress spring 16 and be depressed in the locating hole 15 and stop, make the upper surface of inner core magnetic sheet 8 be lower than the connecting line of inner core 1 and core overcoat 2, at this moment, free the rotary resistance between inner core 1 and the core overcoat 2, made it to be in rotatable state; Simultaneously, pellet shot from a slingshot hole 20 on the another side of composite magnetic cards key 5 also is in corresponding with general lock cylinder 11, freed the interconnect function of the inner core that stoped by lock cylinder 11 1 and core overcoat 2, thereby make the composite magnetic cards lock core be in rotary state fully, twist the composite magnetic cards key handle this moment again, form unlocking condition by swinging plate 3 coupled and corresponding lockset internal lock tongue structures, as shown in Figure 1.
