[0026] This specific embodiment is a special vest for restricting chairs, and its structural diagram is shown below. Figures 1-7 As shown, the chair body 1 includes a restraint vest 2, which is used on the chair body 1. The restraint vest 2 has symmetrical fixing straps 3 fixedly connected to the front and rear side walls. The chair body 1 has mounting plates 4 fixedly connected to the rear side wall near the four corners. The mounting plates 4 are U-shaped. One end of each of the four fixing straps 3 passes through the mounting plate 4 and extends to the outside of the mounting plate 4. The mounting plate 4 has a buckle mechanism. The rear side wall of the chair body 1 has a movable opening 18 near the middle. The left and right inner walls of the movable opening 18 are movably connected to a square tube 19. The top of the square tube 19 extends above the chair body 1. The square tube 19 has a square rod 20 inside. The top of the square rod 20 extends to the top of the square tube 19 and is fixedly connected to a guard plate 21. The rear side wall of the square tube 19 and the rear side wall of the chair body 1 are provided with a buffer mechanism.

[0027] The restraint vest 2 in this technical solution is a common item on the market. Different materials of restraint vest 2 can be selected according to needs. The fixing strap 3 is made of plastic, specifically polyethylene, which can be bent to a certain extent without breaking and has a certain degree of sturdiness.

[0028] like Figures 1-5 As shown, the buckling mechanism includes a fixed plate 5 inside the mounting plate 4. The fixed plate 5 is fixedly connected to a uniformly distributed toothed block 11 on the side opposite to the chair body 1. The fixed strap 3 is provided with a uniformly distributed toothed groove 13 on the side opposite to the fixed plate 5. The toothed block 11 matches the toothed groove 13. Round rods 6 are fixedly connected to the four corners of the rear side wall of the fixed plate 5. The rear end of the round rod 6 passes through the mounting plate 4 and is movably connected to the mounting plate 4. A rectangular plate 8 is fixedly connected between the rear ends of the four round rods 6 on the same mounting plate 4. A first spring 7 is sleeved on the side wall of the round rod 6. One end of the first spring 7 is fixedly connected to the fixed plate 5, and the other end is fixedly connected to the inner wall of the mounting plate 4. A handle 9 is fixedly connected to the rear side wall of the rectangular plate 8.

[0029] In this technical solution, the tooth block 11 is made of steel, which can effectively prevent slippage between the tooth block 11 and the tooth groove 13. Furthermore, both the tooth block 11 and the tooth groove 13 are inclined, so that one side of the tooth block 11 and the tooth groove 13 is vertical, which can effectively prevent slippage and better hold them together.

[0030] like Figure 2 and Figure 6 As shown, the buffer mechanism includes an upper U-shaped plate 23 on the rear side wall of the square tube 19, a lower U-shaped plate 24 slidably connected to the rear side wall of the chair body 1 near the middle, a connecting rod 25 movably connected between the left and right inner walls of the upper U-shaped plate 23 and the lower U-shaped plate 24, a second spring 26 fixedly connected to the bottom of the lower U-shaped plate 24, a support plate 27 fixedly connected to the bottom end of the second spring 26, and the front wall of the support plate 27 fixedly connected to the chair body 1.

[0031] The lower U-shaped plate 24 in the design is fixedly connected to a slider on its front wall, and the rear side wall of the chair body 1 is provided with a groove that matches the slider. This prevents the lower U-shaped plate 24 from detaching from the chair body 1 and serves as a limiting position. The elastic force of the second spring 26 needs to be assembled and used according to actual needs.

[0032] The square tube 19 has a threaded hole near the top on its rear side wall. A lead screw 22 is installed in the threaded hole. One end of the lead screw 22 extends into the square tube 19 and contacts the square rod 20. A lever is fixedly connected to the rear end of the lead screw 22, which facilitates the rotation of the lead screw 22. The square rod 20 can be fixed at the required height by the lead screw 22 to accommodate patients of different heights.

[0033] In addition, first positioning wheels 15 are symmetrically arranged on the left and right side walls of the chair body 1. The first positioning wheels 15 are located inside the fixing belts 3. The top and bottom of the first positioning wheels 15 are movably connected to the first connecting plates 14. One side of the first connecting plates 14 is fixedly connected to the chair body 1. Second positioning wheels 17 are arranged on the rear side walls of the four fixing belts 3. The top and bottom of the second positioning wheels 17 are movably connected to the second connecting plates 16. One side of the second connecting plates 16 is fixedly connected to the rear side wall of the chair body 1.

[0034] The first positioning wheel 15 and the second positioning wheel 17 both serve to reduce the resistance of pulling the fixing strap 3, reduce the friction of the fixing strap 3 on the chair body 1, and improve service life and save effort.

[0035] The four mounting plates 4 have rectangular openings 10 at the top and bottom respectively. The top and bottom of the fixing plate 5 are fixedly connected to limit blocks 12. One side of the limit block 12 passes through the rectangular opening 10 and extends to the outside of the mounting plate 4. The limit block 12 can prevent the round rod 6 from deforming and being damaged when the fixing plate 5 is pulled, thus effectively improving the stability of use.

[0036] In addition, a type of restraint chair includes the aforementioned restraint chair vest.

[0037] Working Principle: In use, the restraint vest 2 is first worn backwards on the patient, with the opening facing the back. Then, the fixing straps 3 on the restraint vest 2 are passed around the first positioning wheel 15 and inserted into the mounting plate 4. If there is resistance, the fixing plate 5 can be pulled backwards by the handle 9 to compress the first spring 7, allowing it to easily pass through the mounting plate 4 and around the front of the second positioning wheel 17. Next, the handle 9 is released, and the first spring 7 simultaneously pushes the fixing plate 5 forward, causing the toothed block 11 to engage with the toothed groove 13. This ensures that the fixing straps 3 will not loosen when pulled, providing excellent fixation. The fixing straps 3 can be pulled appropriately according to the patient's body shape to prevent the patient from tilting left, right, or forward. The guard plate 21 supports the patient's head, preventing it from tilting left or right. When a struggling patient tilts their head backwards, it will push the guard plate. 21 swings backward, and the backward swing of the guard plate 21 and square tube 19 presses down on the connecting rod 25, causing the lower U-shaped plate 24 to move downward and compress the second spring 26. This can play a buffering role and effectively protect the head, avoiding hard impacts to the head. When the patient's head moves forward, the second spring 26 pushes the lower U-shaped plate 24 and connecting rod 25 upward through the rebound force, so that the square tube 19 and upper U-shaped plate 23 return to the vertical state. The height of the guard plate 21 can be adjusted according to the patient's height. After loosening the screw 22, the height of the guard plate 21 and square rod 20 can be adjusted upward or downward. After adjustment, the screw 22 can be tightened to fix the position of the square rod 20 after adjustment. When it is necessary to remove the restraint vest 2, the handle 9 can be pulled by the above operation to separate the toothed block 11 from the toothed groove 13, and then the fixing strap 3 can be pulled out for reuse.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
