Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] See attached document Figure 1-7 ,include:

[0031] Main support plate 10;

[0032] Chin support plate 20;

[0033] Two height adjustment mechanisms are provided. One of the height adjustment mechanisms includes an adjustment box 31 and a movable plate 32. The movable plate 32 is slidably connected to the inner wall of the adjustment box 31. The two ends of the main support plate 10 are respectively fixedly connected to the outer walls of the two adjustment boxes 31. The two ends of the chin support plate 20 are respectively connected to the two movable plates 32 through self-locking components. The distance between the adjustment box 31 and the movable plate 32 in the height adjustment mechanism can be adjusted, thereby adjusting the distance between the main support plate 10 and the chin support plate 20.

[0034] A locking assembly is used to lock and fix the adjusting box 31 and the movable plate 32. The locking assembly includes a mounting groove 35 formed on the side wall of the movable plate 32, and a rod 34 is slidably connected to the inner wall of the mounting groove 35. The side wall of the adjusting box 31 has multiple positioning holes 33. The end of the rod 34 is movably inserted into the interior of one of the positioning holes 33. A first spring 36 is fixedly installed on the end wall of the rod 34, and the end of the first spring 36 away from the rod 34 is fixedly connected to the inner wall of the mounting groove 35. When adjusting the distance between the adjustment box 31 and the movable plate 32, the insertion rod 34 can be pressed to move the insertion rod 34 out of the positioning hole 33, thereby releasing the limitation of the insertion rod 34 on the movable plate 32. At this time, the movable plate 32 can be pulled to adjust its position in the adjustment box 31. After adjusting the position of the movable plate 32, under the elastic force of the first spring 36, the insertion rod 34 can be pushed into the positioning hole 33, thereby completing the fixation of the movable plate 32 and the adjustment box 31 after adjustment.

[0035] The self-locking assembly includes a lock box 40 fixedly mounted on the outer wall of a movable plate 32. Inside the lock box 40, a ratchet 41 is rotatably connected to the outer wall of the movable plate 32. The side of the ratchet 41 away from the movable plate 32 is fixedly connected to a connecting block 21 via a connecting rod. A pawl 42 is rotatably connected to the outer wall of the movable plate 32, engaging between two adjacent teeth on the outer wall of the ratchet 41. A fixed plate 45 is fixedly mounted on the outer wall of the movable plate 32. A second spring 44 is fixedly connected to the outer wall of the fixed plate 45, with one end of the second spring 44 away from the fixed plate 45 fixedly connected to the outer wall of the pawl 42. A limit post 43 is fixedly mounted on the outer wall of the movable plate 32 (the limit post 43 is used to limit the rotation direction of the pawl 42, such as...). Figure 6 In the middle, to prevent the pawl 42 from rotating counterclockwise); where the chin support plate 20 can still be adjusted in angle, combined with Figure 3 , Figure 6 and Figure 7 As shown, when adjusting, the chin support plate 20 can be rotated counterclockwise. The chin support plate 20 drives the connecting block 21 and the ratchet 41. During the rotation of the ratchet 41, the pawl 42 rotates and engages in the next tooth groove, thereby achieving self-locking after rotation.

[0036] The second spring 44 has a pull rod 46 inside. One end of the pull rod 46 is rotatably connected to the outer wall of the pawl 42. The outer wall of the lock box 40 has a movable groove 47. The end of the pull rod 46 away from the pawl 42 moves through the movable groove 47 and extends to the outside of the lock box 40. In combination with the above self-locking principle, when it is necessary to rotate the ratchet 41 clockwise, the pull rod 46 can be pulled. The pull rod 46 drives the pawl 42 to rotate. At this time, the second spring 44 is in a compressed state. After the end of the pawl 42 is removed from the teeth of the ratchet 41, the pawl 42 can be released from fixing the ratchet 41. At this time, the ratchet 41 can support clockwise / counterclockwise rotation, and the angle of the chin support plate 20 can be adjusted in the opposite direction.

[0037] The fixing component is used to install the main support plate 10 around the neck. The fixing component includes a first fixing strap 11 and a second fixing strap 12, which are respectively fixedly connected to the outer walls of two adjustment boxes 31. The free ends of the first fixing strap 11 and the second fixing strap 12 away from the adjustment box 31 are fixed together by Velcro. When the main support plate 10 is worn around the neck, the main support plate 10 can be placed in front of the chest, and then the first fixing strap 11 and the second fixing strap 12 can be pulled around to the back of the neck. The free ends are then fixed by the Velcro component to complete the wearing of the device.

[0038] Cotton pads are installed on the outer walls of the main support plate 10 and the chin support plate 20, respectively; the cotton pads can be placed on the side walls that come into contact with the patient's skin, thereby improving the patient's skin comfort.

[0039] In this embodiment, when using the neck brace, the height adjustment mechanism can first be adjusted according to the length of the patient's neck. During adjustment, the insertion rod 34 can be pressed to overcome the elastic force of the first spring 36 and move out of the positioning hole 33, releasing the limitation on the moving plate 32. Then, the moving plate 32 is pulled to slide in the adjustment box 31 to change the relative position between the moving plate 32 and the adjustment box 31, thereby adjusting the distance between the main support plate 10 and the chin support plate 20. After the adjustment is completed, the insertion rod 34 is released. Under the elastic force of the first spring 36, the insertion rod 34 is reinserted into the corresponding positioning hole 33, thereby fixing the moving plate 32 and the adjustment box 31 after the adjustment position is adjusted, ensuring the stability of the neck brace height.

[0040] The applicability of the device is improved by adjusting the distance between the chin support plate 20 and the main support plate 10.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
