DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1:

[0019] like Figures 1 to 4 As shown, this embodiment provides a neck fixator, comprising: a back support 1, a front support 2, and a V-shaped shell 3. The back support 1 and the front support 2 are both U-shaped or arc-shaped, and the specific shape depends on actual needs. In addition, a back support sponge pad 11 is provided on the inner side of the back support 1; a front support sponge pad 21 is provided on the inner side of the front support 2; and a shell sponge pad 32 is provided on the inner side of the V-shaped shell 3 to ensure comfort when fixing the neck. The two arms 31 of the V-shaped shell 3 are fixedly mounted on both sides of the back support 1; the two sides of the front support 2 are correspondingly rotatably mounted on the two sides of the back support 1; specifically, the two sides of the front support 2 are hinged to the two sides of the back support 1 through a hinge axis; the V-shaped shell 3 is a shell structure with a V-shaped cavity inside; a driving mechanism and a linkage mechanism are installed in the V-shaped cavity; the driving mechanism drives the front support 2 to rotate through the linkage mechanism; in actual use, the linkage mechanism can drive the front support 2 to rotate about the hinge axis through the linkage mechanism, thereby achieving adjustment of the front support 2 to lift the person's lower jaw, adapting to different people, with wide adaptability and easy adjustment.

[0020] Please refer to Figure 2 and Figure 3 The linkage mechanism includes a crank 41, a return spring 42 and a steel wire 43; the center position of the crank 41 is hinged on the inner side of the V-shaped cavity; an arc-shaped hole 44 is provided on the inner side of the V-shaped cavity; the upper end of the crank 41 is connected to the side of the front support 2 through a connecting shaft, and the connecting shaft is slidably installed in the arc-shaped hole 44; the upper end of the crank 41 is connected to the return spring 42, and the other end of the return spring 42 is fixed to the inner side of the V-shaped cavity; specifically, the inner side of the V-shaped cavity is rotatably installed with a guide pulley 56; the V-shaped cavity is installed along the side wall of the guide tube 57. Ensure that the steel wire 43 will not be mixed up when it is contracted and released; the steel wire 43 is wound around the outside of the guide pulley 56 and passes through the guide tube 57 to ensure that the steel wire 43 is smooth when it is contracted and released; one end of the steel wire 43 is connected to the lower end of the crank 41, and the other end is fixedly connected to the driving mechanism; when in use, the steel wire 43 is contracted and tightened, driving the rotation of the crank 41, and then driving the front support 2 to rotate upward and close to the person's lower jaw to achieve stable lifting; when the steel wire 43 is released, the front support 2 rotates downward under the pull of the return spring 42, making it easy to remove.

[0021] See also Figure 3 and Figure 4As shown, the linkage mechanism includes a knob 51, a worm rod 52, and a turbine 53; a gear box 54 is installed at the top corner of the V-shaped cavity; the knob 51 is fixedly connected to the worm rod 52 coaxially; specifically, one end of the worm rod 52 is rotatably mounted on the front side of the gear box 54, and the end of the worm rod 52 extending from the front side of the gear box 54 is connected to the knob 51. The knob 51 is located outside the V-shaped housing 3 for easy adjustment. The turbine 53 is rotatably mounted between the two side walls of the gear box 54; the worm rod 52 is meshed with the turbine 53; the turbine 53 extends out of the gear box 54 and is symmetrically connected to the winding wheel 55 on both sides of the axle. One end of the steel wire 43 is fixedly mounted in the wheel groove of the winding wheel 55; when in use, by rotating the knob 51, the worm rod 52 and the turbine 53 are driven to rotate, which in turn drives the two winding wheels 55 to rotate, thereby driving the contraction and release of the steel wire 43, facilitating the upward or downward rotation of the front support 2.

[0022] When the present invention is actually used, the knob 51 is rotated to drive the contraction and release of the steel wire 43, thereby driving the rotation of the crank 41; the front support 2 can be easily rotated upward or downward, which is convenient for fixing and disassembling the neck; at the same time, the neck fixer is suitable for different people and has a wide range of applications.

[0023] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
