Description

A kind of handcuffss

Technical field

The utility model relates to a kind of improvement of handcuffss structure.

Background technology

Shown in Fig. 5～10, the end of the built-in lock core 11 of existing handcuffss is provided with protrudes triangular prism 12, is provided with interior tri-angle-holed 13 corresponding to this protrusion triangular prism 12 on the key cylinder 14 of existing handcuffss; Simple, easy to use advantage that this handcuffss 6 have method of operating; But this handcuffss 6 are in use easily replaced key with other article, handcuffss 6 are opened, and be a big defective of existing handcuffss, bring hidden danger to public security work.

Summary of the invention

The utility model is exactly at the problems referred to above, provides a kind of method of operating simple, easy to use, is difficult for by the handcuffss of unnormal unlocking.

For reaching above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises the lock core and the key cylinder of handcuffss, it is the polygon groove that the leading section of its structural feature lock core is provided with medial surface, be provided with thimble in the groove, the height of described thimble is greater than the degree of depth of groove; The end of described key cylinder is set to polygonal cylinder corresponding to the polygon groove of lock core, is provided with centre hole corresponding to the thimble in the lock core groove on the end face of key cylinder.

The beneficial effects of the utility model: 1, the utility model is only at the lock core of handcuffss with improve on the key, the usage of handcuffss makes numerous policeman not have obstacle when using handcuffss of the present utility model without any change, does not also need to adapt to again, method of operating is simple, and is easy to use.

2, when the people wants to insert the groove of lock core with other object, the thimble in the groove, can be effectively with this object blocks outside groove, thereby improved the reliability of handcuffss, it is difficult for by unnormal unlocking.

In the accompanying drawing 1 be lock core, 2 for groove, 3 for thimble, 4 for key cylinder, 5 for centre hole, 6 for handcuffss, 11 for built-in lock core, 12 for protrude triangular prism, 13 for interior tri-angle-holed, 14 be the key cylinder of existing handcuffss.

The specific embodiment

The utility model comprises the lock core 1 and the key cylinder 4 of handcuffss 6, and it is polygonal groove 2 that the leading section of lock core 1 is provided with medial surface, is provided with thimble 3 in the groove 2, and the height of described thimble 3 is greater than the degree of depth of groove 2; The end of described key cylinder 4 is set to polygonal cylinder corresponding to the polygon groove 2 of lock core 1, is provided with centre hole 5 corresponding to the thimble 3 in lock core 1 groove 2 on the end face of key cylinder 4.

The groove 2 of described lock core 1 end is set to interior eight-sided formation, and the shape of key cylinder 4 correspondingly; Because it is cylindrical that eight-sided formation is similar to, therefore, when opening handcuffss 6, need the hardness of key cylinder 4 also bigger, prevent that the suspect from utilizing softer article to make respective shapes handcuffss 6 are opened; In addition, the outer octagonal instrument on the market also seldom, the outer octagon instrument that the centre has the hole does not have especially, this brings bigger difficulty also for suspect's forged key.

Claims (2)

1. handcuffss, the lock core (1) and the key cylinder (4) that comprise handcuffss (6), it is polygonal groove (2) that the leading section that it is characterized in that lock core (1) is provided with medial surface, is provided with thimble (3) in the groove (2), and the height of described thimble (3) is greater than the degree of depth of groove (2); The end of described key cylinder (4) is set to polygonal cylinder corresponding to the polygon groove (2) of lock core (1), is provided with centre hole (5) corresponding to the thimble (3) in lock core (1) groove (2) on the end face of key cylinder (4).

2. a kind of handcuffss according to claim 1 is characterized in that the groove (2) of described lock core (1) end is set to interior eight-sided formation, and the shape of key cylinder (4) correspondingly.
