Improvement of handcuffs safety structure

This creation is an improvement of the safety structure of the handcuffs, especially a safety structure that provides multiple safety locking mechanisms or locking effects, and effectively prevents the handcuffs from being opened in a non-key or various improper manners.

The handcuff security device is used for the device that binds the wrist of the person. It is commonly used in military and police. The handcuff is the body of the two-handed cymbal, and the middle is connected by a chain or the like. The traditional handcuffs are not tightly joined due to the internal locking structure. It is easy to use small and narrow simple tools such as hairpins and clippers to easily insert the handcuffs along the gap, and the anti-smashing mechanism is insufficient. Therefore, in order to improve this problem, Taiwan Patent No. 80215636 "A Handcuffs Anti-Smashing Structure" patent case has disclosed a handcuff anti-smashing structure which improves the structure of a traditional handcuff and has a gear structure in the middle of the two fixing ring hooks. The gear structure destroys the structure of the object to be opened into the handcuff and improves its safety mechanism. The disadvantage is that the other end of the gear is not provided, and the external object may be extended into the handcuff along the end to achieve the purpose of unlocking the lock. .

In view of this, Taiwan No. 102222091 "Handcuffs with Improved Locking Mechanism" discloses the handcuff structure of the improved locking mechanism, which is modified by a receiving groove formed in the middle of the two fixing ring hooks, and a baffle and an elastic member are added. When the movable ring hook is inserted into the accommodating groove, the elastic member pushes the locking piece toward the movable ring hook, and the latching teeth of the locking piece fit the barb tooth row of the movable ring hook, thereby lifting the difficulty of opening the locking state. However, the disadvantage is that if a person operates a sheet or a strip into the gap between the movable hook and the flap, the shackle can still be achieved when the lock is pushed open.

In order to improve the above situation, and with another design, Taiwan No. 104208319 "Handcuffs anti-mite structure" reveals a hand-proof smashing structure, which uses a plug body disposed between the hooks of the two fixing rings to make the card sheet The inner pressing makes the card piece engage with the stud and closes the space in which the locking piece moves upward to prevent the handcuff from being opened.

Typically, these references reveal a number of different internal design security structures in the same size handcuffs. As mentioned above, they are mostly enhanced with a single security structure. Although they are used to restrain the wrists, they are used in handcuffs. The safety of opening is still insufficient; in particular, the design of the handcuff structure is designed in a limited space by modifying the internal structure configuration and interlocking design, in accordance with the specific volume or space specification of the handcuff (ie, without increasing the size of the handcuff). It is a difficult subject to make the handcuff structure have multiple security mechanisms at the same time and improve the safety of handcuffs.

In view of this, the main purpose of the present invention is to provide an improvement of the safety structure of the handcuff, which comprises a fixing ring hook, a movable ring hook pivotally fixed at one end and forming a rotating or swinging freely; the fixing ring hook is assembled with a fixing piece and a bonding piece. , card parts, and gears. A barb tooth row is arranged on one side of the movable ring hook, and the movable ring hook is allowed to rotate to engage the locking piece to form a locking state or to operate the movable ring hook to rotate away from the locking piece, and the locking state is released, and a blocking piece is arranged on the combined piece. Block non-use of keys and improper means to open the lock state. When the movable ring hook is in the latching state, the barb tooth row interacts with the gear to break the intrusion object structure to achieve the function of blocking the entry of the object; and the binding piece and the fixing piece define a receiving groove. The cassette member is accommodated, and the card member can be moved in the receiving slot, and the locking piece is crimped, so that the locking piece cannot be opened, forming a dark locking mechanism to form a multiple safety locking structure, and the handcuff is prevented from being opened. safety.

According to the present invention, there is provided an improvement of the safety structure of the handcuff, wherein a fixing piece, a coupling piece and a gear are arranged between the two fixing ring hooks, and the fixing piece is engaged with the two fixing ring hooks, and the fixing piece fixes the bonding piece therein, fixing The sheet and the bonding sheet are provided with an inner groove and a receiving groove, and the supporting piece is provided with a blocking piece for blocking the entry of the object, and the receiving groove is further provided with a plug portion, a clamping piece, a locking piece and an elastic body, and the elastic body is engaged with the locking piece. The elastic card of the elastic body is coupled to the cassette to form a dark lock mechanism as described above, and the handcuff is improved to be easily opened by various improper (or improper external force) manners.
