Description

Be used for the locking device on the handcuffss

Technical field

The utility model relates to a kind of locking device, particularly a kind of locking device that is used on the handcuffss.

Background technology

At present, all is using with a kind of handcuffss basically in the police station, this handcuffss have been extensive use of decades, though its deft design exists some defectives: at first, the key of this handcuffss is the same, that is to say that a key can drive all handcuffss, greatly reduce the safety of handcuffss like this, if obtained a key in advance by the handcuffs people, he can open handcuffss himself fully and runs away so, even the injury police.Secondly, this handcuffss can not be put handcuffs on the people sometimes, and it is only to shrink during not with key, and its contraction is all not all right sometimes, and reason must be said from its principle.The key of this handcuffss is small circle rings that there is a dentation its inside, it combines with outside movable annulus, outer shroud just can only shrink and can not loosen like this, control small circle ring with key then, the key up time is changeed then small circle ring and can be freed fully, and corresponding outer shroud is just also free, and handcuffss will be untied like this, and as long as stop this moment key is exerted oneself or the extraction key, little ring just can be replied; If but rotate counterclockwise key, small circle ring will be fixed fully, like this outer shroud even shrink all can not, at this moment in time stop firmly or extract key out and also do not reply.At last, the release of this handcuffss by key, loses key and just loses the release ability fully.

Summary of the invention

The purpose of this utility model is at the problems referred to above, design a kind of novel locking device that is used on the handcuffss, it utilizes key and password to combine, making handcuffss depend on key no longer merely can straighten one out and ease out his anxiety, can not occur handcuffss more yet and can't put handcuffs on the people because of human operational error's (do not reply directly after the key counter-rotating and extract out), easy to use, safety improves greatly.

The technical solution of the utility model is: a kind of locking device that is used on the handcuffss, comprise lock body and key, and described key is a cylinder, and it runs through two circular holes on axially, and two circular holes are with axial vertical, and are connected by throat between two circular holes; Described lock body has a sleeve, its interior section is provided with interior plug, the keyhole that always wears tube should be divided into forward and backward two ones by interior plug, the also sheathed impeller-hub of described sleeve, and this impeller-hub one end is equipped with and holds ring, which is provided with two protuberances, this impeller-hub middle part is with spring, and the other end has a cuboid and separates the lock section, and this release minister degree is identical with the key diameter, width equals Circularhole diameter, highly is not more than throat; Described lock body also is provided with two password rotating shafts that are inserted on the sleeve, respectively offers a positioning port that matches with described protuberance on it.

The described lock section end of separating also is connected with the piece of stepping down, and this piece of stepping down is the diameter cylinder identical with separating the lock section width.

Plug rear portion and the corresponding place of described key one circular hole are provided with and allow bit space, its front portion be provided with promotion path by impeller-hub in described, and this promotion path and this allow bit space on same straight line.

It is anterior that described password rotating shaft is held in described interior plug.
