Description

The lock core that a kind of theftproof performance is good

[technical field]

This utility model relates to the technical field of lock core, the technology neck of the lock core that a kind of theftproof performance is good Territory.

[background technology]

Lock core is to control the major part that lock is opened, and is the heart of lockset, refers to can rotate also with key is supporting Drive the core of locking bolt motion, existing technology unlocking mode, be generally adopted by tinfoil and unblank, stannum Paper unblanks to be by being wrapped on general key billet by tinfoil, first passes through tinfoil and is all pushed up by all pellets To peak, then by rocking the key billet with tinfoil, rely on the elastic force extruding tinfoil of spring, thus By changing the thickness of tinfoil, pellet is made to drop to tram and then open tapered end, existing lock core marble Be typically not provided with antitheft draw-in groove and spring fixture block on lock core, therefore can not play the effect preventing tinfoil from unblanking.

[utility model content]

The purpose of this utility model is contemplated to solve the problems of the prior art, proposes a kind of theftproof performance good Lock core, this utility model is by having offered an antitheft groove on existing pellet, and inside lock core It is provided with Spring Card block assembly, so that being blocked by Spring Card block assembly when pellet is by tinfoil top to peak, And then be effectively prevented tinfoil and unblank.

To achieve these goals, the utility model proposes the lock core that a kind of theftproof performance is good, including lock core Cylinder, lock core, limit plunger, marble spring, fixture block holding tank, fixture block spring, fixture block, antitheft upper pellet, Lower pellet, commonly going up pellet, plate device, pellet loose slot and key insertion hole, described lock core is directly pacified It is contained in lock core tube, inside described lock core tube, offers fixture block holding tank and pellet loose slot, described pellet bullet Spring, antitheft upper pellet and common upper pellet are arranged in pellet loose slot by limit plunger, described fixture block spring Being directly installed in fixture block holding tank with fixture block, described plate device is directly connected with lock core, on described lock core Also offering pellet loose slot, described lock core is further opened with key insertion hole, described fixture block includes rectangular portion Point and circular arc curtate, described antitheft upper pellet offers antitheft groove, and antitheft groove offer height Degree, should meet when antitheft upper pellet rises to extreme higher position, and fixture block could be blocked.

As preferably, the quantity of described lower pellet is at least three, and the length of each lower pellet is different, institute State the length degree of depth less than lock core marble loose slot of lower pellet.

As preferably, after lock core is arranged on lock core tube, on pellet loose slot on described lock core and lock core tube Pellet loose slot connect up and down.

As preferably, described common upper pellet is identical with the height of antitheft upper pellet, and with common upper pellet phase The length of the lower pellet coordinated is respectively less than the length of the lower pellet matched with antitheft upper pellet.

As preferably, when correct key inserts, the lifting height of described antitheft upper pellet, should ensure that anti- On robber, pellet can not be blocked by fixture block, and described lock core can normally rotate.

The beneficial effects of the utility model: this utility model is antitheft by having offered one on existing pellet Groove, and inside lock core, it is provided with Spring Card block assembly, so that pellet is by quilt during tinfoil top to peak Spring Card block assembly blocks, and then is effectively prevented tinfoil and unblanks.

Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.

[detailed description of the invention]

Refering to Fig. 1-3, the lock core that a kind of theftproof performance of this utility model is good, including lock core tube 1, lock core 2, Limit plunger 3, marble spring 4, fixture block holding tank 5, fixture block spring 6, fixture block 7, antitheft upper pellet 8, under Pellet 9, common upper pellet 10, plate device 11, pellet loose slot 12 and key insertion hole 13, described Lock core 2 is directly installed in lock core tube 1, and described lock core tube 1 is internal offers fixture block holding tank 5 and pellet Loose slot 12, described marble spring 4, antitheft upper pellet 8 and common upper pellet 10 are installed by limit plunger 3 In pellet loose slot 12, described fixture block spring 6 and fixture block 7 are directly installed in fixture block holding tank 5, institute State plate device 11 to be directly connected with lock core 2, described lock core 2 also offers pellet loose slot 12, described Being further opened with key insertion hole 13 on lock core 2, described fixture block 7 includes rectangle part 71 and circular arc curtate 72, described antitheft upper pellet 8 offers antitheft groove, and antitheft groove offer height, should meet and work as When antitheft upper pellet 8 rises to extreme higher position, fixture block 7 could be blocked, the quantity of described lower pellet 9 At least three, and the length of each lower pellet 9 is different, the length of described lower pellet 9 is less than lock core 2 bullet The degree of depth of subactivity groove 12, the pellet loose slot after lock core 2 is arranged on lock core tube 1, on described lock core 2 12 connect with the pellet loose slot about 12 on lock core tube 1, described common upper pellet 10 and antitheft upper pellet The height of 8 is identical, and the length of the lower pellet 9 matched with common upper pellet 10 is respectively less than and antitheft upper bullet The length of lower pellets 9 that son 8 matches, when correct key inserts, described antitheft upper pellet 8 upper Rise, should ensure that antitheft upper pellet 8 can not be blocked by fixture block 7, and described lock core 2 can normally rotate.

Utility model works process:

The good lock core of a kind of theftproof performance of this utility model in the course of the work, when correct key inserts key Inserting in hole 13, antitheft upper pellet 8, lower pellet 9, upper pellet 10 can be by key top to correct positions Put, so that lock core 2 can rotate, and then drive plate device 11 to open tapered end, when using tinfoil technology When unblanking, when common upper pellet 10 and antitheft upper pellet 8 are all by top to peak, antitheft upper pellet 8 is just Can be blocked by fixture block 7, thus the lower pellet 9 coordinated with antitheft upper pellet 8 cannot make under it by rocking Drop, and then the lower pellet 9 coordinated with antitheft upper pellet 8 will block lock core 2 and make it not rotate, thus Play antitheft effect.

This utility model is by having offered an antitheft groove on existing pellet, and arranges inside lock core Spring Card block assembly, so that blocked by Spring Card block assembly when pellet is by tinfoil top to peak, and then It is effectively prevented tinfoil to unblank.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any to this Scheme after utility model simple transformation belongs to protection domain of the present utility model.
