Abstract
A handcuff structure for preventing illegal opening comprises a lock body with a fixed locking arm, and a locking ring with teeth. Control locking pieces and three rotary gears are arranged inside the lock body. The three rotary gears are arranged in the padlocking direction of the lock body and the locking ring with the teeth in a circular mode. When the locking ring with the gears padlocks the lock body, the rotary gears are just meshed with the locking ring with the teeth and guide the locking ring with the gears to lock the rotary gears tightly. The control locking pieces are arranged behind the rotary gears in a groove of the lock body in an overlapping mode.

Summary of the invention
In order to overcome the defective of prior art, the invention provides a kind of again safety simple in structure, can the illegal handcuffss structure of opening of prevention, its technical scheme is: comprise with fixedly lock body, the band tooth lock ring of hammerlock, be provided with in lock body and control locking plate and three swing pinions.
Three belt lock body and directions that fasten with the tooth lock ring of being arranged on of swing pinions, when being with the tooth lock ring to the lock body padlock, swing pinion is just in time locked with band tooth lock ring interlock and pilot tape tooth lock ring; The control locking plate is stacked at after the interior swing pinion of lock body groove.
Swing pinion is heterotypic gear, and its upper and lower part is made of 1/4 circle four teeth and octadentate gear one respectively.
The control locking plate is three, and the first control locking plate is " L " shape, and its vertical extension is towards the first swing pinion; Be provided with the extension of " L " shape towards the second swing pinion direction at the middle part of the second control locking plate; From control locking plate plane upwards be provided with the extension of " L " shape near the position of end towards the 3rd swing pinion at the 3rd control locking plate, the described locking plate of respectively controlling is integrated formed structure.
Between first and second control locking plate, between the second and the 3rd control locking plate and the 3rd control between locking plate and the down lock body reseting leaf is set, when handcuffss are in locking state, back-moving spring will be controlled locking plate jack-up, the extension of three control locking plates supports respectively on 1/4 crenel slice on the swing pinion corresponding with it, stops swing pinion to turn clockwise.
The control locking plate is provided with fixing hole, so that swing pinion and control locking plate and lock body install and fix.
Lock body, control locking plate adopt stainless steel material, and lock body is provided with mounting cover.
Pair of handcuffs comprises two lock bodies and band tooth lock ring, between use and be connected assembly and connect.
Lock body, control locking plate are provided with keyhole.
The present invention compared with prior art has easy to processly, improves machining accuracy, and the advantage such as cut down finished cost.Locking plate and gear, band tooth lock ring are controlled mutually, and project organization is simply ingenious, reliable, excellent performance, through up to ten thousand experiments, the record of illegally not opened.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1 and Figure 2, prevent illegal handcuffss structure of opening, comprise lock body, band tooth lock ring 2 with fixing hammerlock, described lock body with fixing hammerlock is made of upper and lower lock body (1-1,1-2), is articulated in the arc of upper down lock body fixedly between the hammerlock with tooth lock ring 2 via a pivot activity.Be provided with the space that can hold swing pinion and control locking plate in the upper down lock body, swing pinion is special shape gear, its upper and lower part is made of 1/4 circle four teeth and octadentate gear one respectively, three swing pinions go in ring and are arranged on lock body and the direction that fastens with tooth lock ring 2, when being with the tooth lock ring to the lock body padlock, swing pinion 4 is and pilot tape tooth lock ring locking meshing with band tooth lock ring just in time; The control locking plate is three, and the first control locking plate 3-1 is " L " shape, and its vertical extension is towards the first swing pinion; Be provided with the extension of " L " shape towards the second swing pinion direction at the middle part of the second control locking plate 3-2; Be provided with facing up the extension of " L " shape from locking plate towards the 3rd swing pinion near the position of end at the 3rd control locking plate 3-3.Three control locking plates are stacked in the lock body groove after the swing pinion, between first and second control locking plate, between the second and the 3rd control locking plate and the 3rd control between locking plate and the down lock body reseting leaf is set.When handcuffss are in locking state, back-moving spring will be controlled locking plate jack-up, and the extension of described three control locking plates supports on 1/4 crenel slice on the swing pinion corresponding with it, stop swing pinion to turn clockwise, and prevent illegal unlatching.After using key operated handcuffss, key drives three control locking plates and moves down, and compresses back-moving spring, discharges 3 swing pinions, and swing pinion can be turned clockwise, and allows band tooth lock ring 2 to break away from lock body, reaches the purpose of opening handcuffss.The control locking plate is provided with fixing hole 7, is used for swing pinion and control locking plate and lock body are installed and fixed.Lock body, control locking plate are provided with keyhole 6, are used for the normal handcuffss of opening.
Lock body, control locking plate adopt stainless steel material.Lock body is provided with mounting cover 1-3.
Pair of handcuffs comprises two lock bodies and band tooth lock ring, between use and be connected assembly and connect.The lock body rear portion is provided with and connects the tail structure that is connected assembly.Said structure is prior art and repeats no more.
Above-described embodiment only is for explanation the application, but not to restriction of the present utility model, for example said structure can be applied in the anti-illegal opening structure of fetters, as long as variation, the modification to the above embodiment all will drop in the scope of the utility model claims in the application's connotation scope.
