Abstract

The utility model discloses an anti-releasing hand cuffs and shackles, comprising upper and lower corresponding fastening components, a rotating shaft, an iron chain connecting hole and a key, wherein, a groove (11) is arranged on a contact surface corresponding to the free end of the upper fastening component (1); a convex block (32) is arranged on the corresponding contact surface matching with the free end of the lower fastening component (3); the end of the convex block (32) is a hook (33) having a guide inclined plane; a latch pin (4) which can stretch along axial direction is arranged in matching with the convex block (32); the latch pin (4) is positioned in the groove hole (6) of the upper fastening component (1); the other end of the latch pin (4) is provided with a spring (7); a poking groove (41) is arranged on the latch pin (4); the poking piece (51) of a lock core is arranged in the poking groove (41). The hand cuffs and shackles of the utility model is rapid and convenient to use, can effectively prevent prisoners unlocking easily, and has stable performance as well as good safety, which completely satisfy detention houses and prisons for restricting prisoners.

Description

The anti-fetters of freeing

Technical field:

The utility model relates to a kind of fetters in the constraint utensil that law enforcement behavior uses.

Background technology:

The loose collar of present common fetters puts and has some unidirectional teeth, on the Fixing shrink ring of fetters, be provided with the tooth lock of the unidirectional stop of band holddown spring, when user mode, the restraint ring set only can be to the direction motion of locking, when opening fetters, thereby the movable ring set that unidirectional stop tooth is lifted make fetters with general key is to the direction activity of unclamping, thereby the purpose that reaches locking and open.Obviously, this fetters is simple in structure, use efficient and conveniently, but also exist the convict can be with starting the stop tooth in the tooth lock such as article such as iron wire, waddy, cloths easily or the tooth locking device damaged and reaching unlatching fetters purpose, for law enforcement behavior brings hidden danger.

The utility model content:

The purpose of this utility model provide a kind of use efficient and convenient, prevent the fetters that the convict opens easily voluntarily.

The anti-fetters of freeing of the utility model, comprise corresponding upper and lower two clamp structures and rotating shaft, iron chains connecting hole and key, have groove tightening on the free-ended corresponding contact surface of member, suitable touching in the following free-ended correspondence of clamp structure is provided with projection on the face, the end of projection is the hook that has guiding surface, with the suitable latch that can stretch vertically that is provided with of projection, this latch is positioned at the slotted eye that tightens firmware, this latch other end is with spring, establish allocating slot on this latch, the plectrum of lock core places in the allocating slot.

Upper and lower clamp structure is free-ended to be laminated or to collide fetters of the present utility model by making, projection guiding surface on the following clamp structure is pushed the contrary spring force direction of latch to slotted eye, the latch end is stretched in the hook of projection by the tension force effect of spring again, the locking fetters, in this process, the plectrum of lock core is in upright state all the time in allocating slot; When needs are opened fetters, use the key rotary locking cylinder, make plectrum horizontal flat in allocating slot, a side of plectrum acts on allocating slot in the horizontal flat process of plectrum, makes in the contrary spring tension direction of latch to contract, and makes latch break away from hook, opens fetters.Fetters of the present utility model uses efficient and convenient, can prevent effectively that the convict from opening easily voluntarily, and stable performance, has safety, satisfies detention house and prison constraint convict fully and uses.

Assembling drawing when Fig. 1 frees the fetters locking state for the utility model is anti-.

Assembling drawing when Fig. 2 frees the fetters opening for the utility model is anti-.

The specific embodiment:

As shown in Figure 1 and Figure 2, the utility model fetters comprises; On corresponding, following two clamp structures 1,3 and connect the rotating shaft 2 of these two clamp structures, iron chains connecting hole 31 and lock core 5, have groove 11 tightening on the member 1 free-ended corresponding contact surface, suitablely down be provided with projection 32 on the clamp structure 3 free-ended corresponding contact surfaces, projection 32 is the hook 33 that has oblique guide face with latch 4 corresponding these sides, when locking, stumble mutually with hook 33 in the end of latch 4, for locking, it is convenient to open, the going deep into length and will suit of the degree of depth of hook 33 and latch 4 ends, latch 4 is positioned at the slotted eye 6 that tightens firmware 1 and can stretches vertically, latch 4 can be axis body, latch 4 other ends are with spring 7, and the tension force of spring 7 will suit.Establish allocating slot 41 on this latch 4, the plectrum 51 of lock core 5 places in the allocating slot 41, and the length of allocating slot 41 and plectrum 51 horizontal strokes width at ordinary times adapt.

Claims

1, a kind of anti-fetters of freeing, comprise corresponding on, following two clamp structures and rotating shaft, iron chains connecting hole and key, it is characterized in that: described tightening on the free-ended corresponding contact surface of member (1) has groove (11), suitable touching in the following free-ended correspondence of clamp structure (3) is provided with projection (32) on the face, the end of projection (32) is the hook (33) that has guiding surface, with the suitable latch (4) that can stretch vertically that is provided with of projection (32), this latch (4) is positioned at the slotted eye (6) that tightens firmware (1), this latch (4) other end is with spring (7), establish allocating slot (41) on this latch (4), the plectrum of lock core (51) places in the allocating slot (41).
