CN203247954U - Anti-theft unmachined key body and lockset device - Google Patents

Abstract

An anti-theft unmachined key body and lockset device comprises an unmachined key body and a lockset matched with the unmachined key body. A linear guide groove is formed in the unmachined key body, a turning angle guide groove is further formed in the turning angle position of the tail end of the linear guide groove in the unmachined key body, an auxiliary guide groove is formed in at least one of the linear guide groove or the turning angle guide groove in the unmachined key body, and the linear guide groove is of an inclined groove shape. A linear guide bar is formed in a lock hole of the lockset, a curved guide bar is further formed in the turning angle of the tail end of the linear guide bar, an auxiliary guide bar is formed on at least one of the linear guide bar and the bent guide bar in the lock hole, and the linear guide bar is of an inclined bar shape. The shape of the lock hole of the lockset which is in shape correspondence with the unmachined lock body is formed to be of a branch shape instead of a curved line shape to greatly increase the complexity of the shape of the lock hole of the lockset, the anti-theft function of the lockset is improved, and therefore the essential benefit that the lockset is difficult to unlock by thieves using unlocking tools and thus the property and the life safety of the public are effectively protected is achieved.

Description

Key embryo that can be antitheft and lock device

Technical field

The utility model relates to a kind of device, especially a kind of key embryo and lock device that can be antitheft.

Background technology

At present, if existing mainly be on key embryo cutting forming directly to or the key embryo of oblique guide groove, for being used in conjunction with the lockhole of the lockset of corresponding design, with the effect of unblanking or locking, but when actual implementation and operation, find, existing simple moulding directly to or the key embryo of oblique guide groove, the lockhole of the lockset of its corresponding design also can only form linearity and can't form the curved line shape, therefore cause the as easy as rolling off a log unlocking tool of tabular that utilizes of robber to insert in the lockhole of this lockset, unblank with forced rotating, cause the heavy losses on common people's property, even jeopardize common people's life security.

Summary of the invention

In order to overcome the unicity of existing key embryo; the utility model provides a kind of key embryo and lock device that can be antitheft; significantly increase the complexity of its lockhole shape of lockset; improve its antitheft effect; make the robber be difficult to unblanking lockset be pried open to reach, effectively protect the real benefit of common people's property and life security.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of key embryo and lock device that can be antitheft; comprise key embryo; form the wire guide groove at key embryo; make again key embryo in the terminal corner moulding corner of wire guide groove guide groove; other makes key embryo form auxiliary guide groove to being less than wire guide groove and corner guide groove on one of them; this wire guide groove is the skewed slot shape; the lockset that matches with key embryo; the lockhole of lockset forms the wire sliver; make again the wire sliver in terminal corner moulding bending sliver; other makes lockhole to being less than the wire sliver and the bending sliver forms auxiliary sliver on one of them; this wire sliver is the slanted bar shape; its lockhole of lockset that is correspondingly-shaped with key embryo forms dendroid by the curved line shape; significantly to increase the complexity of its lockhole shape of lockset; improve its antitheft effect, make the robber be difficult to unblanking lockset be pried open to reach, effectively protect the real benefit of common people's property and life security.

The beneficial effects of the utility model are; the utility model provides a kind of key embryo and lock device that can be antitheft; significantly increase the complexity of its lockhole shape of lockset; improve its antitheft effect; make the robber be difficult to unblanking lockset be pried open to reach, effectively protect the real benefit of common people's property and life security.

1. key embryos among Fig. 1,2. wire guide groove, 3. corner guide groove, 4. auxiliary guide groove.

1. key embryos among Fig. 2,2. wire guide groove, 3. corner guide groove, 4. auxiliary guide groove, 5. lockset, 6. lockhole, 7. wire sliver, 8. bending sliver, 9. auxiliary sliver.

The specific embodiment

In the drawings, a kind of key embryo and lock device that can be antitheft, key embryo 1 has the wire guide groove 2 of the skewed slot shape of moulding, make again key embryo 1 in wire guide groove 2 terminal corner moulding corner guide grooves 3, other makes key embryo 1 form auxiliary guide groove 4 to being less than wire guide groove 2 and corner guide groove 3 on one of them, auxiliary guide groove 4 is mutual angle of inclination with wire guide groove 2 and corner guide groove 3 and sets up, the lockset 5 that matches with key embryo 1, the lockhole 6 of lockset 5 forms wire sliver 7, make again wire sliver 7 in terminal corner moulding bending sliver 8, other makes lockhole 6 form auxiliary sliver 9 to being less than wire sliver 7 and bending sliver 8 on one of them.

Claims (1)

1. One kind can be antitheft key embryo and lock device, comprise key embryo and lockset, it is characterized in that: form the wire guide groove at key embryo, this wire guide groove is the skewed slot shape, make again key embryo in the terminal corner moulding corner of wire guide groove guide groove, other makes key embryo form auxiliary guide groove to being less than wire guide groove and corner guide groove on one of them, the lockset that matches with key embryo, the lockhole of lockset forms the wire sliver, this wire sliver is the slanted bar shape, the wire sliver is in terminal corner moulding bending sliver, and other makes lockhole form auxiliary sliver to being less than wire sliver and bending sliver on one of them.
