Description

Technical Field

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

[0002] An interrogation chair is a chair used in more serious occasions. It is a special chair used in public security departments, procuratorates, courts, prisons and other places where interrogations are conducted. It is restrictive and can effectively restrict the actions of the person being interrogated and prevent him from endangering himself or others.

[0003] Most existing interrogation chairs only emphasize confinement and restraint. During the interrogation process, the suspect often breaks down emotionally or tries to break free. At this time, the interrogation chair can only ensure that the suspect cannot break free, but there are still defects in the reminder function. When the suspect has excessive behavior, the interrogation chair itself cannot send out a warning signal to remind him. There is still room for improvement in the structure. Utility Model Content

[0030] See also Figures 1 to 5 The utility model provides a technical solution: an interrogation chair, comprising an interrogation chair body 1 and a limiting cage 2, wherein one side of the front end of the interrogation chair body 1 is rotatably connected to the limiting cage 2 through a rotating shaft;

[0031] The first limiting leg cuffs 10 are fixed to the front end of the supporting legs 6 of the interrogation chair body 1 and play the role of fixing the suspect's lower limbs in the interrogation chair body 1;

[0032] An active limiting structure 18, which is fixed inside the shackle body 17 of the first limiting shackle 10, and plays a role in strengthening the limiting in the first limiting shackle 10;

[0033] The leg cuffs of the interrogation chair have an automatic tightening structure. When the suspect refuses to cooperate or tries to break free, the leg cuffs will automatically narrow after being stressed, reducing the possibility of the suspect breaking free. At the same time, the narrowed leg cuffs will serve as a warning to the suspect, reminding him to cooperate in completing the interrogation process. Embodiment 2

[0034] On the basis of the first embodiment, the interrogation chair body 1 includes a backrest 3, a limit seat 4, a semicircular limit plate 5, a support leg 6, a side limit plate 7, a first anti-roll baffle 8, a second anti-roll baffle 9 and a first limit footcuff 10. One side of the backrest 3 is fixedly connected to the limit seat 4, and the other side of the backrest 3 is rotatably connected to the semicircular limit plate 5 through a rotating shaft. The bottom end of the backrest 3 is fixedly connected to the support leg 6, and two groups of side limit plates 7 are symmetrically fixed on both sides of the middle section of the support leg 6. Two groups of first anti-roll baffles 8 are symmetrically fixed on the rear side of the bottom end of the support leg 6. The front side of the bottom end of the support leg 6 is fixedly connected to the second anti-roll baffle 9, and the front side of the bottom of the support leg 6 is fixedly connected to two groups of first limit footcuffs 10;

[0035] The limiting cage 2 includes a cage frame 11, a shackle fixing frame 12, a second limiting shackle 13, a support plate 14, a wrist limiting shackle 15 and a front chest baffle 16. The bottom of the cage frame 11 is fixedly connected to the shackle fixing frame 12, the front side of the shackle fixing frame 12 is fixedly connected to two sets of second limiting shackles 13, the top of the cage frame 11 is fixedly connected to the support plate 14, the top of the support plate 14 is fixedly connected to two sets of wrist limiting shackles 15, and the front side of the support plate 14 is fixedly connected to the front chest baffle 16;

[0036] When in use, the suspect is fixed on the interrogation chair seat, the semicircular limiting plate 5 is rotated and fixed in the limiting seat 4, the upper body of the suspect is clamped, and then the ankles of the suspect are fixed in two sets of first limiting leg cuffs 10 and corresponding second limiting leg cuffs 13 to fix the lower body of the suspect, and the cage frame 11 is rotated so that the front chest baffle 16 performs secondary fixation on the upper body of the suspect. The cage frame 11 can limit the lower body of the suspect. The use of the first anti-roll baffle 8 and the second anti-roll baffle 9 increases the contact area between the interrogation chair and the ground, reducing the situation where the interrogation chair tilts due to the suspect's non-cooperation in shaking the interrogation chair. Embodiment 3

[0037] On the basis of the first embodiment, the first position-limiting leg cuffs 10 and the second position-limiting leg cuffs 13 correspond to each other, and the first position-limiting leg cuffs 10 and the second position-limiting leg cuffs 13 have the same structure;

[0038] The first position-limiting shackle 10 comprises a shackle body 17, a driven position-limiting block 18 and an active position-limiting structure 19. The active position-limiting structure 18 is fixedly connected to the rear side of the shackle body 17, and four groups of driven position-limiting blocks 19 are fixedly connected to the front side of the shackle body 17. The four groups of driven position-limiting blocks 19 are located on both sides of the active position-limiting structure 18.

[0039] The shackle body 17 includes a fixed shell 20, an arc-shaped limiting plate 21, a two-stage limiting plate 22 and a limiting protrusion 23. The front end of the fixed shell 20 is fixedly connected to the arc-shaped limiting plate 21. The fixed shell 20 and the arc-shaped limiting plate 21 are hollow inside. The front end of the arc-shaped limiting plate 21 is provided with an opening, and the two-stage limiting plate 22 is slidably connected in the opening. A plurality of groups of limiting protrusions 23 are fixed on the surface of the two-stage limiting plate 22.

[0040] The active limiting structure 18 includes a support seat 24, a first spring 25 and a slider 26. The front end of the support seat 24 is fixedly connected to one end of the first spring 25, and the other end of the first spring 25 is fixedly connected to the slider 26.

[0041] The driven limit block 19 includes a second spring 27 and a push plate 28, and the front end of the second spring 27 is fixedly connected to the push plate 28;

[0042] The rear end of the support seat 24 is fixedly connected to the inner wall of the fixed housing 20, the front end of the slider 26 is fixedly connected to the rear end of the second-stage limit plate 22, the top of the slider 26 is provided with a first plug hole, and the top of the fixed housing 20 is provided with a second plug hole corresponding to the first plug hole, the rear end of the second spring 27 is fixedly connected to the inner wall of the arc-shaped limit plate 21, and the front end of the push plate 28 is fixedly connected to the rear end of the second-stage limit plate 22;

[0043] Brittle plastic plugs are inserted into the first and second plug holes, and the brittle plastic has the characteristics of high hardness and great brittleness;

[0044] When the suspect becomes emotionally unstable during interrogation, he or she will often engage in extreme behaviors such as shaking his or her limbs to break free. If the suspect's legs break free at this time, the ankle will violently hit the second-stage limit plate 22, which will retract inwards under the force, causing the slider 26 to slide in the fixed housing 20. At this time, the first socket and the second socket are not in the same vertical plane, and the brittle plastic pin is broken under the force. At this time, the slider 26 is suddenly pushed outward under the elastic force of the first spring 25, pushing the second-stage limit plate 22 outward. The second spring 27 simultaneously uses the push plate 28 to drive the second-stage limit plate 22 to be pushed outward. The limiting protrusion 23 on the surface of the second-stage limit plate 22 will directly compress the suspect's ankle skin to increase the degree of confinement. The physical discomfort can serve as a warning and reminder to the suspect.

[0045] A person skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention, including the claims, is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
