Description

Anti-picking handcuffs

Technical Field

The utility model relates to a police apparatus, in particular to handcuffs.

Background

Handcuffs are the most commonly used and essential as rings for law enforcement. As is well known, most handcuffs used in the ministry of public security and judicial expertise of China are common handcuffs, and the unlocking of the common handcuffs adopt the principle of a lock. The ordinary handcuffs have the advantages of simple structure and convenience in use, but the problem that a prisoner uses iron wires, needles, wooden sticks and other articles to pry the handcuffs is also solved, so that the prisoner escapes, the social security is possibly threatened, and the capturing and duty efficiency of public security personnel is influenced. In order to overcome the defects, the prior art has provided three-row-tooth anti-poking handcuffs (with the patent application number of 201820273752.9), the traditional single-row tooth structure on the ring is changed into the three-row tooth structure, a separation groove is arranged between adjacent teeth, after the structure is adopted, the three rows of parallel handcuffs teeth are matched with barbs on three independent swinging rods, when the lock is unlocked, the three independent swinging rods are needed to be poked simultaneously to open the handcuffs ring, and the anti-prying performance is improved to a certain extent. However, when a lawbreaker adopts three independent small iron wires, the handcuffs can be pried to be opened, so that the barbs on the swing rod are downwards separated from the handcuff teeth of the handcuff rings, and the handcuff rings can be reversely rotated to be opened.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: provides a novel anti-prying handcuff structure which can effectively prevent the handcuffs from being pried by tiny objects.

The utility model provides a solution of its technical problem is: pick-proof handcuffs comprises a copying body and a fan beam, wherein a lock box is arranged on the upper portion of the copying body, one end of the fan beam comprises a tooth buckle, a swing rod is arranged in the lock box, teeth buckled with the tooth buckle are arranged in the swing rod, a gear is further arranged in the lock box, the gear is rotatably connected with the copying body and is located at the front end of the swing rod, and the gear is meshed with the tooth buckle.

The utility model has the advantages that: the utility model adds a gear at the front end of the swing rod, when the handcuffs are locked, the tooth buckle of the fan beam firstly passes through the gear and then enters the swing rod, and the handcuffs are locked by utilizing the mutual fastening of the tooth buckle and the teeth; when a lawbreaker wants to pry open the handcuffs, the gear meshed with the tooth buckles of the fan beam is arranged at the front end of the swing rod, and small objects such as steel wires cannot penetrate through the swing rod and the tooth buckles of the fan beam, so that the possibility of prying open the handcuffs is fundamentally avoided.

As a further improvement of the above solution, the lock case includes an entrance, and the gear is located at the entrance of the lock case.

As a further improvement of the above technical solution, an elastic member is further disposed in the lock case, and one end of the elastic member abuts against the swing rod, and the other end abuts against an inner wall of the lock case. Preferably, the elastic member is a spring plate, pretightening force is provided through the spring plate, and when the tooth buckle of the fan beam enters the swing rod, the fan beam can only rotate in one direction.

As a further improvement of the technical scheme, the lock box further comprises a locking block, the locking block is connected with the lock box in a sliding mode, the locking block comprises a limiting protrusion, and the swing rod is provided with a top block. After the handcuffs are locked, the locking block is shifted to enable the limiting protrusions of the locking block to be abutted to the ejection block of the swing rod, so that the swing rod cannot swing, the handcuffs are locked, and the handcuffs are further prevented from being pried open illegally.

As a further improvement of the technical scheme, the copying body comprises a front panel and a rear panel, the lock box is clamped between the front panel and the rear panel, the front panel and the rear panel are fixedly connected through a plurality of rivets, and one rivet penetrates through the gear. The rivets of the front panel and the rear panel are used as rotating shafts of the gears, so that the structure of the handcuffs can be simplified.

Meanwhile, all technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

Referring to fig. 1, the anti-prying handcuffs comprise a copied body 100 and a fan beam 200, a lock box 300 is arranged at the upper part of the copied body 100, one end of the fan beam 200 comprises a tooth buckle 210, a swing rod 310 is arranged in the lock box 300, teeth 311 buckled with the tooth buckle are arranged in the swing rod 310, a gear 320 is further arranged in the lock box 300, the gear 320 is rotatably connected with the copied body 100, the gear 320 is located at the front end of the swing rod 310, and the gear 320 is meshed with the tooth buckle 210.

Further as a preferred embodiment, the lock box 300 includes an entrance, and the gear 320 is located at the entrance of the lock box.

In a further preferred embodiment, the lock case 300 further includes an elastic member 330, and one end of the elastic member 330 abuts against the swing lever 310 and the other end abuts against an inner wall of the lock case 300.

Further as a preferred embodiment, the lock box 300 further includes a locking block 340, the locking block 340 is slidably connected to the lock box 300, the locking block 340 includes a limiting protrusion 341, and the swing link 310 is provided with a top block 312.

Further as a preferred embodiment, the copy body 100 comprises a front panel and a rear panel, the lock box 300 is sandwiched between the front panel and the rear panel, the front panel and the rear panel are fixedly connected through a plurality of rivets, and one rivet penetrates through the gear.

Normally, in the unlocked state, the bottom of the fan beam 200 is coupled to the lower portion of the copy body 100, and the fan beam 200 does not enter the lock case 300. When the lock is needed, the fan beam 200 is rotated anticlockwise to enable the fan beam 200 to enter the lock box, the tooth buckle 210 of the fan beam 200 firstly passes through the gear 320 and then abuts against the swing rod 310, and the tooth buckle 210 and the tooth 311 are both in the inclined tooth structure, so that when the fan beam 200 rotates anticlockwise, the tooth buckle 210 enables the fan beam 200 to rotate continuously by jacking up the swing rod 310, and in the rotating process, a cavity between the fan beam 200 and the copy body 100 is smaller and smaller until the cavity reaches a proper size, and then the rotation of the fan beam 200 is stopped. At this time, the fan beam 200 cannot be rotated clockwise due to the abutment of the tooth holder 210 and the tooth 311, and thus, the handcuffs cannot be released. Unless the swing rod is jacked up by the key, so that the tooth holder 210 is separated from the tooth 311. Moreover, after the handcuffs are locked, as the gear 320 is arranged at the entrance of the lock box 300, the gear 320 is meshed with the tooth buckle 210, so that a lawbreaker cannot enter the steel wire from the entrance to pry the swing rod, and the accidental prying of the handcuffs is stopped.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
