[0026] In order to make the above features and advantages of the present utility model more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings.

[0027] As Figures 1-8 shown, this embodiment provides a special chair for laryngoscope, including a chair body 1, a first hinge plate 2, a second hinge plate 3 and a baffle 4.

[0028] The chair body 1 includes a headrest part 11, a backrest part 12, a seat part 13 and a leg placement part 14. A strapping assembly 6 is arranged on the backrest part 12, and a tightening assembly is arranged on the leg placement part 14. A bracket 15 extending upward is formed on the back of the chair body 1. The bracket 15 is fixedly connected to the chair body 1 through a plurality of screws. One end of the first hinge plate 2 is hinged to the upper end of the bracket 15, and the other end of the second hinge plate 3 and one end of the first hinge plate 2 are hinged. Specifically, a first hinge notch is formed on the upper surface of the bracket 15, and first hinge holes are formed on both sides of the first hinge notch. A first convex platform is formed on one side end face of the first hinge plate 2, and first rotating shafts are formed on both sides of the first convex platform. The first rotating shafts are located in the first hinge holes and are rotationally connected; a second hinge notch is formed on the other end face of the first hinge plate 2, and second hinge holes are formed on both sides of the second hinge notch. A second convex platform is formed on one side end face of the second hinge plate 3, and second rotating shafts are formed on both sides of the second convex platform. The second rotating shafts are located in the second hinge holes and are rotationally connected. A tightening assembly is arranged at the hinge joints of the first hinge plate 2 with the bracket 15 and the second hinge plate 3. The tightening assembly includes a rotating column 5. Internal threads are arranged on the inner peripheral surfaces of one of the first hinge holes and the second hinge holes. External threads are arranged on the outer peripheral surface of the rotating column 5. The rotating column 5 is screwed into the first hinge hole or the second hinge hole and abuts against the first rotating shaft or the second rotating shaft. The screwing in and loosening of the rotating column 5 are used to control the tightness of the hinge joints of the first hinge plate 2 with the bracket 15 and the second hinge plate 3, facilitating fixation and adjustment.

[0029] The bracket 15 is fixedly connected to a display screen 151 on one side facing the chair body 1. Specifically, a first snap-fit ​​seat is provided on the side facing the chair body 1 of the bracket 15. The first snap-fit ​​seat includes a base plate and a protrusion. The protrusion is connected to the upper surface of the base plate. The protrusion is in an elongated strip shape. The horizontal interface projection of the protrusion is in a dovetail shape. A dovetail groove is formed on the back of the display screen 151, and the dovetail groove matches the protrusion.

[0030] A reflector 31 is fixedly connected to the inner side of the second hinge plate 3. Specifically, the reflector 31 includes a mirror body and a mounting frame. The mirror body is mounted in the mounting frame. A T-shaped block is formed on the back of the mounting frame. A convex strip 322 is formed on the side of the second hinge plate 3 facing the chair. A T-shaped groove is formed on the side wall of the convex strip 322. The T-shaped groove penetrates one side wall of the convex strip 322 and a side facing the chair body 1. The T-shaped block and the T-shaped groove match each other. The reason why the display screen 151 is not directly arranged on the second hinge plate 3 is that the display screen 151 has a certain weight. If it is installed on the hinge plate, the second hinge plate 3 may move downward under the influence of gravity, affecting normal work.

[0031] The baffle plate 4 is connected to the other end of the second hinge plate 3, and the baffle plate 4 extends toward the chair body 1. Specifically, two spaced limit plates 32 are formed on the back of the second hinge plate 3, and an extended limit strip is formed on the top of the limit plate 32. A through-hole 321 is formed on the side of the limit plate 32. An insert plate 41 extends upward on one side of the baffle plate 4, and a card slot is formed on both sides of the insert plate 41. A constriction is formed at the opening of the card slot. A card ball 411 and a spring are arranged in the card slot. The spring is located between the card ball 411 and the bottom wall of the card slot. The card ball 411 extends out of the constriction. The length of the insert plate 41 is equal to the shortest distance between the two limit plates 32, and the thickness of the insert plate 41 is equal to the distance from the lower surface of the extended limit strip to the back of the second hinge plate 3. The card ball 411 is adapted to the card hole 321, and the baffle plate 4 and the second hinge plate 3 are connected by plugging. The plug plate 41 is inserted into the two limit plate 32 brackets 15. When the card ball 411 and the card hole 321 correspond to each other, the card ball 411 pops out and is inserted into the card hole 321 to achieve fixation. When the plug plate 41 needs to be removed, the plug plate 41 is pulled out with force, and the card ball 411 is retracted into the card slot due to the resistance force around the buckle. The plug plate 41 is pulled out, and without the assistance of external force, the card ball 411 cannot fall out of the card hole 321. The number of card holes 321 is two, and the number of card slots is the same as the number of card holes 321. The four card slots and the card ball 411 make the connection between the plug plate 41 and the limit plate 32 more stable.

[0032] The strap assembly 6 is divided into two groups and arranged at intervals in the upper and lower parts. The strap assembly 6 includes a one-way rotating seat 61, a belt body 62, a first plug 63 and a first socket 64.

One end of the tightening belt 71 is connected to the side wall of the leg placement portion 14, and the other end of the tightening belt 71 is fixedly connected to the second plug 72. The second socket 73 is arranged on the other side wall of the leg placement portion 14. The second plug 72 and the second socket 73 are adapted to each other. When tightening the legs, it is only necessary to hold the second plug 72 around the patient's feet and insert it into the second socket 73. The legs do not need to be tightened like the chest. The legs only need to be controlled to be tightened appropriately. The tightening of the chest will affect the work of the laryngoscope, while the legs are relatively less affected, so the tightening belt 71 can be used.

[0034] Working principle: the patient lies on the chair body 1, and one person presses the rotary column 615 to stagger the deflection pawl 613 and the one-way ratchet 612, and the other person pulls the first plug 63 around the patient and then inserts it into the first socket 64, then loosens the rotary column 615, the spring resets the rotary column 615, and then rotates the rotary column 615 until the patient reaches a suitable tightness to fix the patient's body, and then the legs are fixed through the cooperation of the second plug 72 and the second socket 73, and then the first hinged plate 2 and the second hinged plate 3 are adjusted to a suitable angle for the patient, so that the patient can clearly see the animation in the reflector 31, and then the plug plate 41 is inserted. The cooperation of the reflector 31 and the display mirror can distract the attention of child patients, and the setting of the baffle 4 can prevent the patient from seeing the doctor's tools for laryngoscope out of the corner of his eye, thereby reducing the patient's psychological fear.
