Technical Field

[0001] The utility model relates to the technical field of police interrogation chairs, in particular to a police interrogation chair. Background Art

[0002] Police interrogation chairs are mainly used in the interrogation process of law enforcement agencies to help restrain the interrogated person and ensure the safety and order of the interrogation process. Interrogation chairs are usually used in interrogation rooms of law enforcement or judicial institutions such as police stations. Law enforcement officers will use interrogation chairs to impose necessary restraints on the interrogated person to prevent him from escaping, self-injury or attacking others.

[0003] In modern law enforcement environments, police interrogation chairs are designed to meet the needs of safety and control through their carefully constructed structures and durable materials. In actual use, they are deployed in interrogation rooms, where law enforcement officers use handcuffs and other restraints to secure the wrists of the interrogated person to the armrests of the chair or to specially designed locking points to ensure the stability and reliability of the locks. However, due to the high requirements for safety, interrogation chairs are usually made of heavy materials, which makes them extremely cumbersome to move when not in use, which not only increases the physical burden on staff when carrying them; at the same time, interrogation chairs are often not equipped with flexible universal wheels, which further increases the difficulty of carrying them, forcing staff to invest more labor and time in setting up interrogation rooms. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A police interrogation chair comprises an interrogation chair body 1, two pairs of support plates 2 symmetrically arranged on the interrogation chair body 1 are fixedly connected, a bottom frame 3 is fixedly connected to the bottom of the support plates 2, a horizontal plate 4 is fixedly connected to the opposite side walls of the two support plates 2 in the same pair, a mounting plate 1 5 and a mounting plate 2 6 are fixedly connected to the horizontal plate 4, and a universal wheel 14 is arranged below the mounting plate 2 6;

[0021] A driving structure for driving the universal wheel 14 to move vertically is arranged on opposite sides of the two support plates 2 .

[0022] The driving structure includes a rotating rod 7 rotatably connected to the left mounting plate 1 5, a gear 1 8 is fixedly connected to the top of the rotating rod 7, a screw 10 is rotatably connected to the mounting plate 2 6, a gear 2 9 meshing with the gear 1 8 is fixedly connected to the top of the screw 10, a moving seat 11 is threadedly connected to the screw 10, a limiting rod 12 is fixedly connected to the right mounting plate 2 6, and the moving seat 11 and the limiting rod 12 are vertically slidably connected, a connecting plate 13 is fixedly connected to the bottom of the moving seat 11, and a universal wheel 14 is fixedly installed at the bottom of the connecting plate 13. The setting of the limiting rod 12 ensures that the moving seat 11 moves stably vertically along the axial direction of the screw 10.

[0023] The bottom end of the rotating rod 7 is fixedly connected with a rotating disk 15, so that the rotating rod 7 can rotate more stably.

[0024] The bottom end of the rotating disk 15 is fixedly connected with a turning handle 16. It is convenient for the staff to realize the rotation of the turning rod 7.

[0025] The mounting plate 15 is set in an "L" shape to prevent the interrogated person from touching the gear 18 and causing harm to the interrogator, thereby reducing safety hazards.

[0026] The universal wheels 14 are symmetrically arranged in two parts, which ensures that the force of the universal wheels 14 is balanced, thereby ensuring the stability of the interrogation chair when it moves.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] When using the device, when it is necessary to move the interrogation chair, the staff member holds the handle 16 and rotates the handle 16. The rotation of the handle 16 drives the turntable 15 to rotate, the turntable 15 drives the rotating rod 7 to rotate, the rotating rod 7 drives the gear 1 8 to rotate, the gear 1 8 drives the gear 2 9 to rotate, the gear 2 9 drives the screw 10 to rotate, the screw 10 drives the moving seat 11 to move vertically downward, the moving seat 11 drives the connecting plate 13 to move downward, the connecting plate 13 drives the universal wheel 14 to move downward and contact the ground, so as to facilitate the staff to move the interrogation chair; when it is moved to the appropriate position, the reverse operation is performed to make the universal wheel 14 move vertically upward.
