Anti-seizing anti-riot steel fork head

Abstract

The invention relates to the technical field of security and protection equipment, and discloses an anti-seizing anti-riot steel fork head. The fork head comprises a connecting rod connected with a holding rod and U-shaped forks, the connecting rod is fixedly connected with a connecting base, three sets of hydraulic cavities are formed in the connecting base, and a spherical plugging ball is movably connected into each hydraulic cavity. According to the anti-seizing anti-riot steel fork head, dangerous personnel are limited through the three sets of U-shaped forks at the same time, movement of the dangerous personnel can be limited through one U-shaped fork all the time, due to the fact that the dangerous personnel are limited and cannot do larger actions, the seizing difficulty of the dangerous personnel is increased, meanwhile due to the fact that the held U-shaped forks can freely move within a small range, force unloading and buffering effects are achieved, furthermore, in the process of seizing the U-shaped forks and storing and applying force, the plugging balls repeatedly compress and extract liquid in the hydraulic cavities, under the action of throttling holes and throttling air holes, a part of energy is consumed, and force transmitted to a holder is reduced.

Description

technical field [0001] The invention relates to the technical field of security equipment, in particular to an anti-seizure explosion-proof steel fork fork. Background technique [0002] Anti-riot steel forks are used to restrain dangerous persons such as gangsters holding sharp weapons, drunks, contagious or mentally ill patients. It uses half-moon or U-shaped forks to restrain dangerous persons within a certain range. While not hurting the people around, it can ensure the safety of the holder, and at the same time, it will not cause harm to the bound people. [0003] The biggest function of the anti-riot fork is to limit the movement range of the target person. Its suppression ability is weak. When the target person is relatively strong, it is easy to be seized. In order to prevent the steel fork from being seized, some steel forks have spikes on the outer wall. But in many cases, the danger level of the target person is not high, such as drunks, mental patients with inte...

[0003] The biggest function of the anti-riot fork is to limit the movement range of the target person. Its suppression ability is weak. When the target person is relatively strong, it is easy to be seized. In order to prevent the steel fork from being seized, some steel forks have spikes on the outer wall. But in many cases, the danger level of the target person is not high, such as drunks, mental patients with intermittent attacks, and irrational people who are temporarily emotional. At this time, it is necessary to consider not causing too much damage to them while subduing them, so , steel forks with barbs are not suitable for extensive use, and additional structures are required to prevent the steel forks from being seized
