DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1 , Figure 2 As shown, the utility model includes a support vest, the front of the support vest is provided with a mandibular fixing component, and the back of the support vest is provided with a back head supporting component;

[0027] The support vest comprises a front piece 1 and a back piece 2. The front piece 1 and the back piece 2 are connected at the shoulders by a load-bearing shoulder strap 4. The front piece 1 and the back piece 2 are connected at the waist by an adjusting strap 5. The adjusting strap 5 is provided with a schoolbag buckle. The load-bearing shoulder strap 4 is made of a material with low ductility.

[0028] The mandibular fixing assembly includes a mandibular support pad 11, an upper front base, and a lower front base 10. The bottom surface of the mandibular support pad 11 is vertically fixed to the front sliding rod 9. The front sliding rod 9 passes through the upper front base and the lower front base 10 in sequence. The front sliding rod 9 is slidably connected to the upper front base and the lower front base 10. The upper front base has the function of fastening the front sliding rod 9. The upper front base includes a front part 6, a rear part 7, and a locking nut 8. The locking nut 8 passes through and is threadedly connected to the front part 6 and the rear part 7 in sequence. The front part 6 and the rear part 7 clamp the front sliding rod 9. The front part 6 and the rear part 7 are both provided with grooves adapted to the front sliding rod 9. Head fixing pads 13 are respectively provided on both sides of the mandibular support pad 11. The head fixing pad 13 is fixedly connected to the side of the mandibular support pad 11 through a spring sheet 12. The spring sheet 12 is made of elastic material.

[0029] The back head support assembly includes a back head support pad 14, an upper rear base 16, and a lower rear base 17. The bottom surface of the back head support pad 14 is vertically fixedly connected to a rear sliding rod 15. The rear sliding rod 15 passes through the upper rear base 16 and the lower rear base 17 in sequence. The rear sliding rod 15 is slidably connected to the upper rear base 16 and the lower rear base 17, and the rear sliding rod 15 is in strong friction contact with the upper rear base 16.

[0030] In order to improve the stability of the device, there are two front sliding rods 9 arranged side by side, and there are two rear sliding rods 15 arranged side by side.

[0031] In order to further improve the comfort, a first soft cushion is provided on the top surface of the chin support pad 11 , and a second soft cushion is provided on the top surface of the back of the head support pad 14 .

[0032] In order to further make the back of the head support pad 14 fit the back of the human head, the back of the head support pad 14 is rotatably connected to the rear sliding rod 15, and the rotation point between the back of the head support pad 14 and the rear sliding rod 15 is a strong friction connection.

[0033] In order to improve the comfort and ventilation of the device, the front sheet 1 and the back sheet 2 are both made of hard materials, and both the front sheet 1 and the back sheet 2 are provided with ventilation holes 3.

[0034] In actual use, the user directly puts on the support vest over the head, the load-bearing shoulder strap 4 is less deformed, and the height of the support vest is relatively fixed. By adjusting the length of the adjustment belt 5, the support vest is relatively fixed;

[0035] After fixing the support vest, adjust the height of the chin support pad 11 and fix the chin support pad 11 by tightening the locking nut 8 to clamp the front sliding rod 9 to support the chin. Under the action of the spring 12, the head fixing pad 13 clamps the head to prevent the head from shaking left and right unconsciously.

[0036] The back head support pad 14 is pulled up, and can be kept stable under the strong friction effect, supporting the back of the human head, preventing the head from tilting back, and reducing fatigue.

[0037] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
