Description

A kind of anti-riot confinement ring

Technical field

The utility model belongs to defence apparatus field, is specifically related to a kind of anti-riot confinement ring.

Background technology

At present, locate the defence instrument commonly used for a kind of fixing semicircular metal antiriot fork hospital, school and many unit entrance guards, have structure simple, cheap, easy to use, the feature such as to be widely used.But in actual use, find that metal antiriot fork also exists obvious drawback, main manifestations is: because its top is open architecture, after target is pitched, its backward backward be just easy to avoid constraint; Even if target is forced to dead angles such as wall limits in addition, if it holds to becket or the handle of metal antiriot fork, slightly firmly resistance is just easy to escape, and even also likely robs metal antiriot fork, continues to implement to destroy.

Utility model content

The purpose of this utility model is to provide a kind of anti-riot confinement ring, can subdue suspected target fast and effectively.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of anti-riot confinement ring, comprise by two ring arm form can the rotating ring of folding, the root of two ring arm is hinged and symmetrically by cylindrical hinge, the two ends of spring are separately fixed on the afterbody of two ring arm, and the top of two ring arm can folding under the effect of cylindrical hinge and spring; Cylindrical hinge is fixed on one end of pull bar, and the other end of pull bar is fixed on control handle, and the outer cover of pull bar is equipped with the execution sliding sleeve for push-and-pull two ring arm foldings.

Foam-rubber cushion is provided with inside two described ring arm.

Described pull bar is provided with and slides over for preventing two ring arm from closing rear execution the spring retainer card that pull bar slides.

Described rotating ring, cylindrical hinge, spring, execution sliding sleeve, pull bar and control handle are stainless steel.

Described execution sliding sleeve and the outer surface of control handle are provided with anti-skidding rubber pad.

Be annular or oval ring after described rotating ring is closed.

The diameter of described annular is 150 ~ 800mm, and the long axis length of oval ring is 180 ~ 1000mm, and minor axis length is 150 ~ 500mm.

The length of pull bar is 1000 ~ 2000mm.

Relative to prior art, the utility model has following beneficial effect:

The anti-riot confinement ring that the utility model provides, wherein two ring arm of rotating ring are hinged by cylindrical hinge, and the two ends of spring are fixed in two ring arm, pull bar is connected with cylindrical hinge, and pull bar is arranged with execution sliding sleeve, the afterbody of pull bar is fixed with control handle, when target is inserted in rotating ring by needs, driven forward performs sliding sleeve, pull back control handle simultaneously, thus drive cylindrical hinge and driving spring, make two ring arm tight closure of rotating ring, to reach the object of constrained objective.Use the anti-riot confinement ring that provides of the utility model can entangle the weak parts of defence such as the neck of target or lower limb easily, make it to lose very soon resistance ability, thus prevent it and implement to destroy or subdued further.The anti-riot confinement ring that the utility model provides have structure simple, cheap, easy to use, act on the features such as remarkable, convenient in the various occasion large-scale promotion use needing defence, as used the entrance guard of hospital department, school, unit and security authority, and use when public safety department executes the task.

Further, the anti-riot confinement ring that the utility model provides, foam-rubber cushion is provided with inside two ring arm of rotating ring, due to the buffering of foam-rubber cushion and the effect of extrusion, target can be reduced by the risk of rotating ring unexpected injury on the one hand, another convenient gap that can significantly reduce between the locked position of target and rotating ring, is difficult to after target is lockable carry out struggle resistance.

Further, owing to being provided with spring retainer card in the utility model on pull bar, when execution sliding sleeve is pushed forward to two ring arm tight closure of rotating ring, spring retainer card ejects from pull bar, blocking execution sliding sleeve makes it can not slide on pull bar, thus withstand cylindrical hinge and make it not rotate, therefore rotating ring cannot be opened from inside by struggle, makes target not easily shake off resistance.

Further, in the utility model, the shape of rotating ring and size meet the size characteristic of human body, are convenient to clamp fat or thin neck, chest, waist and the leg etc. waiting different target of height, facilitate easy-to-use.

Wherein: 1 be rotating ring, 2 being cylindrical hinge, 3 being spring, 4 being pull bar for performing sliding sleeve, 5,6 be control handle, 7 be spring retainer card, 8 for foam-rubber cushion.

Detailed description of the invention

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

See Fig. 1 to Fig. 3, the anti-riot confinement ring that the utility model provides, comprise by two ring arm form can the rotating ring 1 of folding, be annular or oval ring after rotating ring 1 is closed, wherein the diameter of annular is 150 ~ 800mm, the long axis length of oval ring is 180 ~ 1000mm, and minor axis length is 150 ~ 500mm.Foam-rubber cushion 8 is provided with inside two ring arm of rotating ring 1, the root of two ring arm is hinged and symmetrically by cylindrical hinge 2, the two ends of spring 3 are separately fixed on the afterbody of two ring arm, cylindrical hinge 2 is fixed on one end of pull bar 5, the length of pull bar 5 is 1000 ~ 2000mm, the other end of pull bar 5 is fixed on control handle 6, and the outer surface of control handle 6 is provided with for the anti-skidding rubber pad being easy to grip.The outer cover of pull bar 5 is equipped with the execution sliding sleeve 4 for push-and-pull two ring arm foldings that can slide on pull bar 5, the outer surface performing sliding sleeve 4 is provided with for the anti-skidding rubber pad being easy to grip, and pull bar 5 is provided with the spring retainer card 7 slided on pull bar 5 for preventing two of rotating ring 1 ring arm from closing rear execution sliding sleeve 4.Top folding under the effect of cylindrical hinge 2, spring 3 and execution sliding sleeve 4 of rotating ring 1 two ring arm.Rotating ring 1, cylindrical hinge 2, spring 3, execution sliding sleeve 4, pull bar 5, control handle 6 and spring retainer card 7 are stainless steel.

In use, left hand holds and performs sliding sleeve 4 the anti-riot confinement ring that the utility model provides, and the right hand firmly grasps control handle 6.When the defence weak parts such as target neck or lower limb are inserted in after in rotating ring 1, the quick driven forward of left hand performs sliding sleeve 4, right hand cooperation simultaneously pulls back control handle 6 fast, the two makes a concerted effort to drive cylindrical hinge 2, spring 3 is driven to pull two ring arm quick-makes of rotating ring 1, target is firmly locked, spring retainer card 7 ejects from pull bar 5 simultaneously, blocking execution sliding sleeve 4 makes it not slide, thus withstand cylindrical hinge 2 and make it not rotate, therefore rotating ring 1 cannot be opened from inside by struggle, makes target not easily shake off resistance.And due to the buffering of foam-rubber cushion 8 and the effect of extrusion, target can be reduced by the risk of rotating ring 1 unexpected injury on the one hand, another convenient gap that can significantly reduce between the locked position of target and rotating ring 1, is difficult to after target is lockable carry out struggle resistance.If locking position is neck, can before and after or left and right promote control handle 6, compressing neck target was fallen.If locking position is lower limb, then firmly front and back pull control handle 6, and target disequilibrium is fallen down, and are now just easy to subdue target.When needs release target, pressing spring retainer card 7, firmly pulls back simultaneously and performs sliding sleeve 4, rotating ring 1 can be opened, target be released.
