Abstract

The utility model relates to a pair of open-proof handcuffs, which is composed of a set of handcuffs and a key. A set of three axially arranged unlocking marbles and four positioning marbles are arranged in the lock core of the handcuff. A set bar is combined with a spiral cam at the upper part of a falling pawl by means of a rotary pin. Pressing and twisting the set bar by means of the key can cause the falling pawl and a handcuff chain tooth to engage or disengage. Thus, the handcuffs are opened or locked. The key is made into a cylinder with an inner and an outer keys, and the outer wall of the key is provided with a set of circular arc grooves. Compared with the existing handcuffs, the utility model has the advantages of enhanced rigidity, enhanced strength, enhanced reliability, beautiful appearance, handy use and flexible use. The utility model causes opening the handcuffs easily without a purpose-made key to become impossible.

Description

Open-proof handcuffs

The utility model relates to a kind of bailiff's apparatus, the promptly anti-handcuffss of opening.

The existing handcuffss office of unblanking mostly is single safeguard procedures, general lock core is with a polygonal jack, cooperate a key that coincide with it, locking bolt is twisted the handcuffs death situation attitude that certain angle just can be removed handcuffss, and the handcuffs ring has only a kind of elasticity, the flexibility of its use, intensity aspect exist not enough, and causing is not being had key but can open handcuffss easily under with the situation of other object yet by the handcuffs person, make handcuffss lose due effect.

The purpose of this utility model is to provide a kind of anti-handcuffss of opening that design at the above-mentioned deficiency that has handcuffss now.

The utility model is made up of one group of handcuffs and key, establishes 4 axial location pellets shot from a slingshot and 3 pellets shot from a slingshot of unblanking in the handcuffss lock core, and the handcuffs hand portion then is made up of anti-reverse ratchet on the handcuffs ring and the detent mechanism under the locking bolt.Detent mechanism and locking bolt are shipped and resell on another market by one and are placed the effect of shipping and reselling on another market in the ratchet spiral cam, can press stubborn locking bolt to make ratchet and ratchet interlock or disengagement by key, and key also is the special tectonic according to the handcuffss tapered end, the appearance that is made into the inside and outside key of tubulose band and also has the arc groove that 3 degree of depth do not wait in front end outer wall cambered surface, the utility model has increased the handcuffs ring thickness in addition, change the sunk head rivet of handcuffs ring rotating shaft into 120 ° of countersunk not chipped rivets, its rigidity is greatly increased, rotate flexibly at each position.

The utility model is compared with existing handcuffss, anti-opens measure because unlocking mechanism has changed the mode of unblanking and increased several, makes it not have under the situation of special key to be become by exoneration easily impossible, and reliability increases greatly.Moreover the utility model can select handcuffs dead and from putting handcuffs on the position as required, under handcuffs state certainly, handcuffss can be struck to the appropriate location, and anti-road changes ratchet-gear wheel to be made by the handcuffs person and only may further lock and can not open, and its flexibility is better.

Now in conjunction with the accompanying drawings the utility model is described in detail.

The utility model is made up of one group of handcuffs and key.

The formation of handcuffss comprises: handcuffs ring (13), the rotating shaft (rivet) (15) of handcuffs ring, handcuffs cover (14), core retainer plate (2), ratchet (9) and ratchet (12) etc., locking bolt (3) places in the core retainer plate (2), it is outer, have the gap of 2.7mm between internal diameter, and keyway is separately arranged respectively.There are one group 4 around the locking bolt axially around location pellet shot from a slingshot (5) and 3 the unblank pellets shot from a slingshot (4) of axle at a distance of 70 °, ratchet (9) places the locking bolt lower end, it with the locking bolt bound fraction be the spiral cam structure, it moves axially down by the drive that acts on locking bolt (3) rotation that places shipping and reselling on another market in it (10), thus the action of finishing out, locking handcuffs.

Figure 1 shows that the utility model handcuffs dead position, ratchet this moment (9) and ratchet semi-ring (12) interlock, 4 location pellet shot from a slingshot (5) and 3 pellets shot from a slingshot of unblanking (4) are in correct position separately, if need to change handcuffs death situation attitude, need to exceed 3 pellet shot from a slingshot compressings of unblanking of locking bolt (3) end face, to making the locking bolt lower surface, pellet shot from a slingshot (5) upper surface, location, pellet shot from a slingshot (4) lower surface of unblanking becomes a circumferential plane, and then make locking bolt clockwise rotate certain angle, then back three marble springs (6) in the direction of the clock of 4 on the lock collar (7) will withstand in 33 pellet shot from a slingshot holes of unblanking of locating on pellets shot from a slingshot (5) the insertion locking bolt separately, this is the state of handcuffs certainly of handcuffss, under this state, can hold the handcuffs neck firmly strikes ratchet semi-ring (12) to wrist, overcome the pressure of compression spring (8) to ratchet semi-ring tooth inclined-plane and pawl teeth cambered surface are skidded, make ratchet semi-ring (12) under impact force action, go back to the wrist that handcuffs the people again, can only further be locked and can not open by the handcuffs person.If need mention ratchet, make ratchet and ratchet take off height, then need make locking bolt (3) by (10) rotational slide in the spiral shell cam (20) of ratchet of shipping and reselling on another market again, make ratchet (9) upwards move 2.9mm by sliding pin (11) (2) compressing compression springs (8) in core retainer plate, thereby the degree of depth of ratchet engagement ratchet semi-ring 2.6mm is thrown off, finish and open handcuffss.The whole process of opening and pinning need be pressed to twist and be finished with key, key is a tubular, it along axial line on the same cross section external diameter of key head be provided with the external key (18) long apart from end face 2mm, on internal diameter, be provided with internal key (17), with the exterior arc surface of external key (18) symmetry on to have at a distance of angle be 70 ° 3 arc grooves (19) that do not wait with the end face degree of depth, this groove is in order to oppress 3 pellets shot from a slingshot of unblanking (4), and interior external key can insert respectively in the keyway of locking bolt (3) and core retainer plate (2), rotates to drive locking bolt.
