Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 give, including stool 1, the rear side of stool 1 upper end is rotated and is connected with axial pivot 2 about, be equipped with the back 3 of upper and lower direction on the pivot 2, sliding connection has upper and lower direction and the forward U-shaped board 4 of opening on the back 3, it has the splint 5 of V-arrangement respectively to articulate on the left and right sides wall of U-shaped board 4, the opening of two splint 5 is relative, but be equipped with left and right directions and the push pedal 6 of back-and-forth movement in the U-shaped board 4, both ends are connected with splint 5 through connecting rod 7 respectively about the push pedal 6 is articulated, the front end of push pedal 6 is equipped with the baffle 9 that is located between two splint 5 through.

In order to enable the rotating shaft 2 to rotate, the right side of the stool 1 is provided with a fixing box 10, the right side of the rotating shaft 2 is coaxially provided with a worm wheel 11 positioned in the fixing box 10, the fixing box 10 is rotatably connected with a worm 12 meshed with the worm wheel 11, and the rear end of the worm 12 penetrates through the fixing box 10 and is coaxially provided with a hand wheel 13.

In order to facilitate the U-shaped plate 4 to slide up and down, the backrest 3 is provided with a sliding groove 14 in the up-down direction, and the sliding groove 14 is connected with a sliding block 15 fixedly connected with the U-shaped plate 4 in a sliding manner.

In order to enable the push plate 6 to move back and forth, the rear end of the push plate 6 is rotatably connected with a screw rod 16 which is in front and back axial directions, the screw rod 16 is in threaded connection with the U-shaped plate 4, a through hole which is coaxial with the screw rod 16 is formed in the sliding block 15, and a knob 17 is coaxially arranged at the rear end of the screw rod 16, extending out of the through hole.

In order to improve the fixing effect, the left side of the upper end of the stool 1 is provided with a fixing belt 18.

In order to improve the comfort of the patient, the front end face of the baffle plate 9 is an arc-shaped face which is axially concave upwards and downwards, and the front end of the baffle plate 9 is provided with an elastic cushion 19.

When the utility model is used, the initial state of the device is that the lower end surface of the slide block 15 is contacted with the lower side wall of the chute 14, and the backrest 3 is in a vertical state;

when the baffle 9 is positioned right behind the head of the infant, the U-shaped plate 4 stops moving, the head of the infant is in contact with the elastic cushion 19, the knob 17 is rotated clockwise, the knob 17 drives the screw 16 to rotate clockwise, the screw 16 drives the push plate 6 to move backwards, the push plate 6 drives the baffle 9 to move backwards through the connecting rod 8, and the head of the infant synchronously moves backwards;

when the baffle 9 moves backwards, the push plate 6 drives the front ends of the two splints 5 to swing relatively through the connecting rod 7, then the push plate 6 moves backwards, the front ends of the two splints 5 are contacted with the forehead of the patient, when the head of the infant is clamped and fixed by the two splints 5, the knob 17 stops rotating, and because the screw 16 has self-locking property, the head of the infant cannot drive the front ends of the two splints 5 to swing back, and at the moment, the head of the infant cannot rotate;

the free end of the fixing belt 18 is pulled to further fix the infant on the device, so as to prevent the infant from moving;
