Hand lock device

Abstract

The invention discloses a hand locking device and relates to the technical field of mechanical devices. The hand locking device comprises a shell, a driving device, a locking device and a guide device, wherein the guide device is arranged at the bottom of the shell, the driving device is arranged on the side surface of the shell, and the locking device is arranged at the upper end of the shell. The hand locking device is simple to operate, low in manufacture cost and convenient for case investigators to control. As long as upward and downward motion is controlled by a motor, opening or closing can be realized. Only downward motion can be controlled through manual work. Through a spring, when locking is carried out, an electric nose and a friction plate are separated from a flange head and rotate, and the whole U-shaped elbow can rotate downwards, so that safety is improved. After locking is finished, if the U-shaped elbow is manually pulled, the electric nose and the friction plate cannot rotate due to pressure increase, the U-shaped elbow cannot be pulled out, and the accidents of suspect escape or self-mutilation and the like can be effectively prevented from occurring.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to a hand locking device. Background technique [0002] The interrogation seat is a seat specially used for interrogating suspects by public security organs. The traditional interrogation seat only has a simple handcuff mechanism. Some suspects are unwilling to cooperate during the interrogation. Simple handcuffs are difficult to lock during the interrogation, and it is easy to handle cases Personnel or self-harm and other situations that threaten the safety of others and themselves, and locking and unlocking are relatively cumbersome. [0003] In order to facilitate the control of the suspect, parts such as handcuffs and handcuffs will be added to the interrogation seat. Through the above-mentioned interrogation seat, the excessive movement of the interrogated person can be controlled, which not only protects the suspect but also protects the interrogation personnel. . ...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the handcuffs used on the interrogation chairs of the public security and judicial departments in our country are ordinary handcuffs, and even the hand locking devices on some interrogation chairs directly use bicycle locks. The opening and locking of ordinary handcuffs all use the principle of lock

This kind of ordinary handcuffs or bicycle locks has a simple structure, but the entire use process requires manual participation, and the process of unlocking and unlocking is very cumbersome, especially when the criminal suspect does not cooperate, it is difficult to lock.

The efficiency of public security personnel's interrogation and handling of cases is affected
