Problems solved by technology

But there is following shortcoming in existing steel fork: 1) existing steel fork suppresses the prisoner by pressing down the prisoner's body,
[0003] It cannot be used effectively when there are no barriers such as buildings, walls or fences. 2) When suppressing prisoners or thugs, the prisoner or thugs can grasp the steel fork with both hands and use a little force to move the steel fork away from the waist and chest. It is easy to escape and escape, and the steel fork does not have a corresponding effect; 3), the shape of the existing steel fork body is open, and the prisoner can only be suppressed by obstacles. During the escort process, the prisoner is easy to escape and cannot be caught. Restrain and arrest criminals
If a steel ring is used to trap the prisoner, it can effectively solve the defect that the prisoner is easy to escape during the escort process of the steel fork, but the existing steel ring is just an ordinary steel ring, and it is not easy to trap a person with a fixed steel ring , it is more difficult to catch, time-consuming and labor-intensive
[0004] Chinese patent CN202403613U discloses a steel fork for police, including steel fork, high-voltage electric contact, gas injector, strong light, fork handle, high-voltage electric switch, gas injector switch, strong light switch, rubber sleeve , the steel fork is fixedly connected to the fork handle, the high-voltage electrical contact is arranged on the outer surface of the steel fork and the front half of the fork handle, and the fork handle is provided with a gas injector, a strong light, a high-voltage electric switch, a gas injection light switch, strong light switch; when performing tasks, the strong light, gas injector and high-voltage electricity can be controlled according to the specific situation, so as to quickly control criminals and improve the efficiency of law enforcement. fatal injury
The structure of the steel fork is complex, long-term use, and the limiting parts are easily damaged

Embodiment 1

[0042] Anti-riot automatic steel ring for police use, the structure is as follows Figure 1-Figure 7 As shown, it includes a handle and a steel fork body arranged at the front end of the handle. The steel fork body is in the shape of a hollow tube inside. The steel fork body includes a pair of bifurcated outer tubes 10 that are bifurcated into two strands. The whole body of the fork is semicircular, and the fixed pin 7 is fixed in the middle of the semicircular steel fork body. The two bifurcated outer tubes 10 are symmetrical to the longitudinal line where the fixed pin 7 is located. . Inner tube 11 is all arranged in two bifurcated outer tubes 10, and the radian of inner tube 11 is identical with the radian of bifurcated outer tube 10, and inner tube 11 can stretch out and indent bifurcated outer tube 10, and inner tube 11 and fixed pin 7 is provided with a spring 4 that ejects the inner tube 11 out of the outer tube, and the outer wall of the inner tube 11 is provided with...

Embodiment 2

[0050] Police anti-riot automatic steel ring, the structure is the same as described in embodiment 1, the difference is that

[0051] structured as Figure 8 As shown, the limit guide device includes a guide positioning sleeve 2 arranged at the end of the bifurcated outer tube and a guide pin 1 fixed on the inner side wall of the bifurcated outer tube, and the end of the inner tube 11 in contact with the spring 4 is provided with a guide ring. 23. A positioning ring 21 is set above the guide ring 23 on the inner tube 11. The positioning ring 21 is located at the position of 1 / 3~1 / 4 of the inner tube. The inner tube between the guide ring 23 and the positioning ring 21 is sleeved There is an inner tube locking ring 22, and an inner tube positioning hole is arranged on the inner tube locking ring 22. When the inner tube 11 retracts into the bifurcated outer tube 10 and locks, the protruding point 18 stretches into the inner tube locking hole 19 and the inner tube. The inner tub...

Abstract

The invention relates to a police antiriot automatic steel rim comprising a handle portion and a steel fork body. The steel fork body is in the shape of a hollow tube and includes a pair of forked outer tubes diverged into two parts. A fixing pin is arranged inside the tubes between the pair of the forked outer tubes. Inner tubes are arranged in the two forked outer tubes, the shapes of the inner tubes are matched with the shape of the forked outer tubes, and the inner tubes can be telescoped relatively to the forked outer tubes. A spring used for ejecting the inner tubes out of the outer tubes is arranged between the inner tubes and the fixing pin. Limit guiding devices used for controlling movements of the inner tubes are arranged at the end of the forked outer tubes. An inner tube locking device is arranged on the outer side wall of the forked outer tubes close to the fixing pin. The police antiriot automatic steel rim is simple in structure, once any part of the body of a prisoner or a thug touches a locking connection rod, the inner tubes in the forked outer tubes are instantly ejected out to form annularity with the forked outer tubes, the thug is locked inside the annular steel rim and can be arrested and subdued rapidly, the arrested prisoner or thug is not easy to escape, and barriers are omitted in the arresting process.

Description

technical field [0001] The invention relates to a steel ring, in particular to a steel ring used by police or security personnel when suppressing criminals and thugs, and belongs to the technical field of security equipment.
