[0002] Psychiatry is a department in the hospital that treats neurological diseases that are mainly manifested in behavioral and psychological disorders. The restraint chair is an extremely common medical device in the psychiatry department. The restraint chair is a soft-padded sofa. The difference from an ordinary chair is that it can fix a person's legs, chest, and arms through straps to restrain a person's behavior. It can also make patients more comfortable when using it, facilitate patients to eat, and enhance the therapeutic relationship.
[0003] During the treatment of the patient, when the assistance of the restraint chair is needed, the restraint chair base is first moved to the designated position by the universal wheels, and then the patient is allowed to sit on the restraint chair base. At this time, the patient's back is in contact with the backboard, and then the restraint plate is installed on the restraint chair, thereby limiting the patient's upper body, and then the patient's arms are passed through the restraint belt, and then the patient's behavior is restrained, thereby assisting the doctor in treating the patient; but during the use of the restraint chair, after the restraint chair is moved to the designated location by the universal wheels, the restraint chair is usually only fixed by the universal wheels, which results in a smaller contact area and friction between the restraint chair and the ground, making the stability of the restraint chair poor, and during the treatment of the patient, there may be violent resistance, which may cause the restraint chair to easily shift, thereby affecting the doctor's treatment of the patient.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-Figure 7 The utility model provides a technical solution: a restraint chair with stable limit, comprising a restraint chair base 1, a backboard 2 and a restraint plate 3, the backboard 2 is docked on one side of the top of the restraint chair base 1, and the restraint plate 3 is arranged above the restraint chair base 1, and restraint belts 4 are installed on both sides of the top of the restraint plate 3, a universal wheel 5 is installed at the bottom end of the outer wall of the restraint chair base 1, and a limiting mechanism 6 is arranged on the outer wall of the universal wheel 5, and the limiting mechanism 6 includes a driving motor 601, a rotating gear 602, a transmission gear 603, a rotating column 604, a guide rod 605, a fixing plate 606, a support rod 607, a fixed suction cup 608, a support column 609 and a spring 610, the top of the inner wall of the restraint chair base 1 is connected to the driving motor 601 through a mounting seat, and the output end of the driving motor 601 is docked with the rotating gear 602, and the outer wall of the rotating gear 602 is meshed on both sides. It is connected to a transmission gear 603; a rotating column 604 is welded inside the transmission gear 603, and guide rods 605 are welded on both sides of the outer wall of the rotating column 604; the bottom end of the guide rod 605 is connected to a fixed plate 606 through a slide rail, and support rods 607 are butt-jointed on both sides of the bottom end of the fixed plate 606; a fixed suction cup 608 is butt-jointed at the bottom end of the support rod 607, and a support column 609 is welded at the middle of the fixed plate 606; a spring 610 is fixedly connected to the top end of the inner wall of the restraint chair base 1, and a guide cavity that is butt-jointed with the fixed plate 606 is opened in the middle of the restraint chair base 1; the top end of the spring 610 is in contact with the fixed plate 606, and an elastic telescopic mechanism is formed between the fixed plate 606, the spring 610 and the restraint chair base 1, the rotating column 604 and the restraint chair base 1 are rotationally connected, and the fixed plate 606 and the support column 609 are both slidingly connected to the restraint chair base 1.
[0027] In specific implementation, when the restraint chair is needed for assistance during the treatment of the patient, in order to prevent the restraint chair from deviating and affecting the treatment, when it is necessary to limit the position, the drive motor 601 is started first. Since the output end of the drive motor 601 is connected to the rotating gear 602, the drive motor 601 starts to drive the rotating gear 602 to rotate forward, and since the rotating gear 602 is meshed with the transmission gear 603, the rotating gear 602 rotates forward to drive the transmission gear 603 to rotate reversely, and then the transmission gear 603 reverses to drive the rotating column 604 to reverse, and since the rotating column 604 is connected to the guide rod 605, the rotation of the rotating column 604 drives the guide rod 605 to rotate together;
[0028] Because the bottom end of the guide rod 605 is connected to the fixed plate 606 through the slide rail, the guide rod 605 reverses to generate a thrust on the fixed plate 606, so that the fixed plate 606 moves downward along the guide cavity, and because the fixed plate 606 is connected to the support rod 607 and the support column 609, the movement of the fixed plate 606 drives the support rod 607 and the support column 609 to move together, and the fixed plate 606 squeezes the spring 610 when moving downward, causing the spring 610 to deform, and then the elastic force generated by the reset of the spring 610 assists the fixed plate 606 to return to its original position;
[0029] Until the support rod 607 drives the fixed suction cup 608 to dock with the smooth ground, the support column 609 docks with the preset fixed cavity on the ground, thereby limiting the position of the restraint chair base 1, and increasing the fixed area and friction between the restraint chair and the ground, thereby improving the stability of the restraint chair base 1, preventing the restraint chair base 1 from shifting arbitrarily and affecting the doctor's treatment, thereby facilitating stable limiting and anti-drifting when the restraint chair is in use.
[0030] See also Figure 1-Figure 4 , Figure 8 It can be seen that the outer wall of the constraint plate 3 is provided with an adjustment mechanism 7, and the adjustment mechanism 7 includes a fixed column 701, a rotating disk 702, a bevel gear A703, a bevel gear B704, a guide plate 705, a fixed seat 706, a fixed pin 707, a threaded rod 708 and a threaded column 709. The top sides of the constraint chair base 1 are welded with fixed columns 701, and the outer wall of the fixed seat 706 is welded to the constraint plate 3; the bottom end of the fixed column 701 is internally connected to the rotating disk 702, and the outer wall of the rotating disk 702 is welded with a bevel gear A703, and the bevel gear A703 is welded to one side of the outer wall of the rotating disk 702. The outer wall is meshingly connected with a bevel gear B704, and a threaded rod 708 is docked inside the bevel gear B704, and a threaded column 709 is threadedly connected to the outer wall of the threaded rod 708; the top of the threaded column 709 is docked with a guide plate 705, and the top of the guide plate 705 is docked with a fixed seat 706, and a fixing pin 707 is slidably connected inside the fixed seat 706; the bottom end of the threaded rod 708 is connected to the restraint chair base 1 through a bearing seat, the outer wall of the threaded column 709 is slidably connected to the fixed column 701, and the top of the threaded column 709 is fixedly connected to the guide plate 705.
[0031] In specific implementation, when the restraint chair is needed to assist in the treatment of the patient, due to the different heights of the patients, the restraint plate 3 needs to be adjusted to correspond to the patients. Since the fixing seat 706 is connected to the restraint plate 3, the fixing seat 706 is connected to the guide plate 705, and the fixing pin 707 is passed through the fixing seat 706 and the guide plate 705, so that the restraint plate 3 is installed on the restraint chair, and the restraint plate 3 can be removed by moving the fixing pin 707.
[0032] Because the rotating disk 702 is connected to the bevel gear A703, the rotating disk 702 is first manually rotated to drive the bevel gear A703 to rotate, and because the bevel gear A703 is meshingly connected to the bevel gear B704, the rotation of the bevel gear A703 drives the bevel gear B704 to rotate, and then the rotation of the bevel gear B704 drives the threaded rod 708 to rotate, and because the threaded rod 708 is meshingly connected to the threaded column 709, the rotation of the threaded rod 708 causes the threaded column 709 to move upward, thereby generating an upward thrust on the guide plate 705, causing the guide plate 705 to move upward along the fixed column 701 until the guide plate 705 drives the constraint plate 3 to move to the specified position, and then adjusts the height of the constraint plate 3 to correspond to the patient's height and usage habits, thereby reducing the patient's discomfort during treatment, thereby facilitating adjustment when the restraint chair is used.
[0033] To sum up, when this kind of restraint chair with stable limit is used, the restraint chair base 1 is first moved to the specified position through the universal wheel 5, and then the patient is allowed to sit on the restraint chair base 1. At this time, the patient's back is in contact with the backboard 2, and then the restraint plate 3 is installed on the restraint chair, thereby limiting the patient's upper body, and then the patient's arms are passed through the restraint belt 4, and then the patient's behavior is restrained, thereby assisting the doctor to treat the patient. This is the existing technology and will not be elaborated on here. The restraint chair base 1 is limited by the limiting mechanism 6, and the fixed area and friction between the restraint chair and the ground are increased, thereby improving the stability of the restraint chair base 1, and then preventing the restraint chair base 1 from arbitrarily shifting and affecting the doctor's treatment, thereby facilitating stable limiting and anti-shifting. The height of the restraint plate 3 is adjusted by the adjustment mechanism 7 to make it correspond to the patient's height and usage habits, thereby reducing the patient's discomfort during treatment. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
