Abstract

Disclosed is a pick-proof safe handcuff. The handcuff belongs to the technical field of public security and police devices. The handcuff is characterized in that a spacing tube is disposed in a key hole. The spacing tube is in sliding fit with the key hole. The top end of the spacing tube is a conical top. A turning neck is disposed along the forward direction of the conical top. A tension force spring is disposed at the back part of the inner side of the spacing tube. A spacing rod is fixed to the outer sidewall of the spacing tube. A spacing rod hole is disposed on the inner sidewall of the key hole. The spacing rod is inserted into and in fit with the spacing rod hole. The beneficial effects are that when another object is inserted into the lock instead of a corresponding key, an umbrella surface angle cannot be found. An object made of hard materials fails to find the angle. An object made of soft materials fails to draw out and rotate without force. The safety and reliability of the handcuff are improved.

Description

Pickproof safety handcuffs

Technical field

The utility model belongs to the police equipment technical field of public security.

Background technology

At present, police handcuffss are all by key operated, and the deficiency of this traditional mode is, can hook and choose snap with elasticity material bar, cause handcuffss to be opened, and reliability is not high.

Summary of the invention

The purpose of this utility model is: a kind of pickproof safety handcuffs is provided, and it has overcome the problem that can open handcuffss without key with other article.

The technical solution of the utility model is: a position-limiting tube is installed in keyhole, position-limiting tube and keyhole are slidably matched, position-limiting tube top is conical head, forward have and turn to draw-in groove at conical head, after in position-limiting tube, tension spring is installed, on position-limiting tube lateral wall, be fixed with limited post, keyhole inside wall has limited post hole, and limited post and limited post hole are inserted and coordinated.

The beneficial effects of the utility model are: in the time hooking lock without key with other article, can not find the angle of umbrella cover: if by harder material, can not find angle; By softer material, unable, can not pull, more do not have strength rotation.Safety, the reliability of handcuffss are improved.

Accompanying drawing explanation

Fig. 1 is the utility model structure chart;

Fig. 2 is the conical head cross-sectional drawing of the utility model position-limiting tube;

Fig. 3 is the utility model keyhole lateral view.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further:.

As shown in the figure, the 1st, keyhole, the 2nd, position-limiting tube, the 3rd, conical head, the 4th, tension spring, the 5th, limited post, the 6th, limited post hole, the 7th, stop spring, the 8th, turns to draw-in groove.

Conical head 3, limited post 5, tension spring 4 form swingle core, tension spring 4 by bar core bullet to right; Limited post hole 6 is on keyhole 1 wall, and wherein limited location device spring 7, is also tension spring, and slideway returned by limited post 5 bullets by this spring, and elastic force direction is to closing direction.

Key inserts and aligns umbrella shape column cap, pull behind 5mm left and right, then to opening direction (clockwise direction) rotation, lock leaves to the direction going out.While closing, stop to right rotation, elastic force effect automatically left, inwards playback, key can be departed to umbrella shape column cap and pulls out to anticlockwise gently.

The key matching with conical head (key is just in time contrary with conical head) is inserted while be rotated in a clockwise direction, key just combines with conical head, pulls out, more opens to clockwise direction rotation.Can prevent from using other TOs, because conical head does not coordinate with other instruments, be oblique because turning to draw-in groove again, cannot hook also reinforcing be pulled outwardly with iron bar etc., more can not rotate, safe and reliable.While being pulled outwardly, limited post is moved to the left in spacing hole, and during to the left side, rotation to the right lock is opened, and when hand unclamps reinforcing, limit spring is by limited post (counterclockwise) ejection to the right, and tension spring rebounds bar core again to approach axis, and lock just returns the state of locking.

Claims

1. a pickproof safety handcuffs, it is characterized in that: a position-limiting tube is installed in keyhole, position-limiting tube and keyhole are slidably matched, position-limiting tube top is conical head, forward have and turn to draw-in groove at conical head, after position-limiting tube is interior, tension spring is installed, on position-limiting tube lateral wall, be fixed with limited post, keyhole inside wall has limited post hole, and limited post and limited post hole are inserted and coordinated.
