Abstract

The utility model discloses a key billet, which mainly comprises a body, wherein more than two protruding parts extend from the surface of the body; optional two adjacent protruding parts are in a symmetrical cross shape; surfaces of outer edges of the protruding parts are provided with groove forming surfaces; and the groove forming surfaces are provided with groove channels and ball locking grooves according to the requirements. More than two groove channels and ball locking grooves are mainly formed on the groove forming surfaces of more than two protruding parts so as to reduce the area of the section of the key billet, so that a gap between corresponding lock holes is relatively narrowed, an anti-theft effect of a lockset can be improved by matching various different types of locking balls; and therefore, matching between the key billet and the locking holes has higher diversity.

Description

Key billet

Technical field

The utility model relates to a kind of key billet, is meant a kind of key billet that can offer specific conduit and lock pearl groove especially, makes its cross-sectional area that can reduce key billet, and dwindles pairing lockhole gap, and then improve the key billet improvement structure of lockset anti-theft effect.

Background technology

Trend according to present social development; The population density is high more than in the past, and social security problem also increases along with the density of population relatively, along with many high building products have more been brought up in the progress in epoch; Old friends also more pay attention to for home safety, so the anti-theft effect of lockset more shows.

See also Fig. 1, Fig. 1 is known key billet schematic perspective view; Can be known that by figure practicing of lockset include key billet 1 and reach the lockhole 3 that is complementary with key billet 1 shape, and general key billet 1 is roughly the form of tabular at present, key billet 1 outer surface is provided with conduit 11 and lock pearl groove 12.

As scheming said showing, conduit 11 and lock pearl groove 12 corresponding being arranged at key billet 1 outer surface are confined on single both side surface of key billet 1 so design in the variation of lock pearl groove 12 and conduit 11 by last; In addition; Lockhole 3 shapes that are complementary with key billet 1 also are subject to the setting of key billet 1; And the design on other shape and structures can't be arranged; Use deathwatch's instrument of iron wire class etc. so can't effectively prevent the thieves or robbers who act under cover of night, and then destroy, separate open keyhole and invade and commit theft within doors, very undesirable on structure design.

Be with, how to make 3 couplings of key billet 1 and lockhole have more variability, simultaneously can reduce the cross-sectional area of key billet 1, and dwindle the lockhole gap, the real problem of considering for industry.

Summary of the invention

In view of this, the utility model provides a kind of key billet that can offer specific conduit and lock pearl groove, makes its cross-sectional area that can reduce key billet, and dwindles pairing lockhole gap, and then improves the key billet improvement structure of lockset anti-theft effect.

In order to solve the problems of the technologies described above, the key billet that the utility model provides consists predominantly of:

Body, body surface extend plural protruding part, and wherein, any two adjacent protruding parts are symmetrical.

As preferred version, protruding part is criss-cross form.

As preferred version, protruding part one end is the inclined-plane.

As preferred version, the protruding part outer fringe surface is for building groove face.

As preferred version, build groove face conduit is set.

As preferred version, build groove face lock pearl groove is set.

The utility model main purpose is; The conduit of offering by the diversification of protruding part outer fringe surface institute and increase the arrangement mode of lock pearl groove; The key billet cross-sectional area is more reduced; Reach between key billet and lockhole coupling and have more diversity, in addition, also can use the lock pearl collocation lock pearl groove of various kind to reach better anti-theft effect.

In addition; The protruding part that utilizes plural extension to be provided with; Make corresponding lockhole gap more narrow, and can prevent that the thieves or robbers who act under cover of night from using deathwatch's instrument of iron wire class etc., and then destroy or separate open keyhole and invade and commit theft within doors; The effect of tool antitheft, the utility model is more applicable on any lock structure certainly.

As stated, the utlity model has following beneficial effect:

1, the said key billet of the utility model, protruding part one end of body is the inclined-plane, and this inclined-plane can guide body accurately to insert in the lockhole, and tool is effect easily;

2, the said key billet of the utility model, the outer rim of protruding part are built groove face can offer conduit and lock pearl groove, makes between body and lockhole coupling to have more diversity;

3, the said key billet of the utility model, offering of lockhole is that shape along with body matches each other, and extends the gap that the protruding part that is provided with can dwindle lockhole, is difficult to utilize the gap of lockhole to carry out larceny;

4, the said key billet of the utility model, lock pearl groove can be used the effect that the lock pearl of various kind is strengthened guarding against theft.
