Description

A kind of supplementary security locking mechanism of lockset and key thereof

[technical field]

The utility model relates to a kind of lockset, particularly be a kind of device that lockset is had Insurance riders.

[background technology]

Lockset is used a lot in daily life, and these locksets all include key and lock core basically, and some pellets shot from a slingshot all are set in the lock core, behind the key that insertion matches, just lockset can be opened.The electric door lock of the motorcycle that these lockset major parts are all used, the door lock of family.Though the theftproof performance to these locksets has all carried out various technological innovations at present, also exists potential safety hazard; The lockhole major part of these locksets is outsides of exposing, the burglar is easy to stretch in the lockhole with master key or other facility and commits a crime, even can't open lockset, also the appearance of perfect lockset lockhole having been done is all non-, even can also block lockhole with foreign matter, make us not knowing whether to laugh or to cry.Particularly the motorcycle user has the user of stolen experience especially the electric door lock of motorcycle to be lacked the sense of security.How these locksets are increased additional together safeties, be to explore in the present technique field but a still unsolved difficult problem always.

[summary of the invention]

Destroyed or block in order to overcome in the prior art lockset lockhole, the perhaps direct deficiency of stealing at the lockhole of lockset, the technical problems to be solved in the utility model provides a kind of supplementary security locking mechanism of lockset, this device can be difficult for the outside function of insurance together that increases of the lockhole of lockset directly lockset to be destroyed by illegal person.

In order to solve the problems of the technologies described above, the utility model adopts following scheme to finish: a kind of supplementary security locking mechanism of lockset, include overcoat, lock housing and lock core, described lock core is installed in the lock housing, described lock housing is placed in the overcoat, the end face center of described overcoat is provided with the keyhole that adapts with the lockset lockhole, circumference in described lock housing radially is provided with the pellet shot from a slingshot hole, described pellet shot from a slingshot is provided with magnetic pellet shot from a slingshot and spring in the hole, and described lock core has flange, is provided with on lock core and the corresponding groove in pellet shot from a slingshot hole, bottom surface at flange is provided with dead bolt, in overcoat, be provided with locking plate, on locking plate, be provided with the chute that matches with dead bolt, and on locking plate, be provided with through hole.

A kind of key that matches with the supplementary security locking mechanism of above-mentioned lockset, include body, with the key piece of lockset lock core coupling, the shoulder of described body is provided with the body of unblanking that is complementary with the lock core lockhole, and this body of unblanking is provided with the magnet that matches with magnetic pellet shot from a slingshot.

To have the device and the coaxial installation of lockset of the utility model structure, and be installed in the outside of lockset lockhole, will play good protective action to lockset, the thief can't directly destroy lockset, and lockset is had good safety performance.And the utility model adopts magnetic pellet shot from a slingshot and the body of unblanking, and itself also has theftproof performance preferably.

After easily this supplementary security locking mechanism being opened, can directly close with hand, on the basis of technique scheme, the edge of lock housing is provided with the deep-slotted chip breaker that penetrates lock housing, is provided with driving lever on described flange, described driving lever extend in the described deep-slotted chip breaker.

[description of drawings]

Further describe the utility model below more in conjunction with the accompanying drawings and embodiments again.

Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model;

Fig. 2 is the structure chart of the utility model lock core;

Fig. 3 is the structure chart of the utility model key.

[specific embodiment]

With reference to Fig. 1, Fig. 2 and Fig. 3, the supplementary security locking mechanism of this lockset, include overcoat 14, lock housing 1 and lock core 5, described lock core 5 is installed in the lock housing 1, inwall at lock core 5 is provided with an elongated slot 8, described lock housing 1 is placed in the overcoat 14, the end face center of described overcoat 14 is provided with the keyhole 15 that adapts with the lockset lockhole, circumference in described lock housing 1 radially is provided with pellet shot from a slingshot hole 2, be provided with magnetic pellet shot from a slingshot 3 and spring 4 in the described pellet shot from a slingshot hole 2, described lock core 5 has flange 7, be provided with on lock core 5 and pellet shot from a slingshot hole 2 corresponding grooves 9, when this installed in off position, magnetic pellet shot from a slingshot 3 was just partly stayed in the groove 9 by the effect of spring 4, thereby just can not rotational lock core, have good safety effect; Be provided with dead bolt 16 in the bottom surface of flange 7, in overcoat 14, be provided with locking plate 10, on locking plate 10, be provided with the chute 11 that matches with dead bolt 16, and a through hole 12 is set on locking plate, for locking plate 10 is arbitrarily slided in overcoat 14, in overcoat 14, also be provided with projection 13, locking plate 10 rotated an angle just it is blocked.For the supplementary security locking mechanism of said structure being opened, need to be equipped with the key that matches with above-mentioned supplementary security locking mechanism, this key include body 17, with the key piece 18 of lockset lock core coupling, shoulder at described body 17 is provided with the body 19 of unblanking that is complementary with lock core 5 lockholes, this body 19 of unblanking is provided with the magnet 21 that matches with magnetic pellet shot from a slingshot 3, and the magnetic pole of this magnet 21 is opposite with the magnetic pole of close pellet shot from a slingshot 3; On unblanking body 19, this also is provided with the projection 20 that is complementary with lock core 5 inwall elongated slots 8, unblank body 19 when stretching in the hole of lock housing 1, because the magnetic of magnet 21 is opposite on pellet shot from a slingshot 3 and the body 19 of unblanking, so pellet shot from a slingshot 3 magnetic field force induced effects break away from the groove 9 of lock core 5, rotate the body 19 of unblanking this moment, the body 19 of unblanking just can drive lock core 5 and rotates, dead bolt 16 on the lock core 5 is stirred locking plate 10 by chute 11, make the keyhole 15 of the through hole 12 aligning overcoats 14 on the locking plate 10, at this moment, pull out the body 19 of unblanking, just can unblank by the lockhole of the keyhole 15 insertion locksets of this attachment device overcoat 14 with key piece 18.Close this supplementary security locking mechanism, can insert with the body 19 of unblanking again, reverse turn lock core 5 can drive locking plate 10 keyhole on the overcoat 14 15 is covered, and reaches the purpose of insurance.In the utility model, the edge of lock housing 1 is provided with the deep-slotted chip breaker 22 that penetrates lock housing 1, is provided with driving lever 6 on described flange 7, and described driving lever 6 extend in the described deep-slotted chip breaker 22; Like this, when closing this supplementary security locking mechanism, just need not to insert again the body 19 of unblanking, as long as stir driving lever 6 with hand, lock core 5 is rotated, and the dead bolt 16 on the lock core 6 also can drive locking plate 12 keyhole on the overcoat 14 15 is covered, and reaches the purpose of insurance equally, this structure is more convenient for the user, makes the use key that the user in use needn't be frequent.To have the device and the coaxial installation of lockset of the utility model structure, and be installed in the outside of lockset lockhole, will play good protective action, have good safety performance lockset.
