[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1-6 This utility model provides a technical solution: an adjustable mouth opening device for rehabilitation, comprising a housing 1, on which an upper jaw pad 4 is provided; an arc-shaped slider 6 is movably arranged inside the housing 1, and the arc-shaped slider 6 can perform arc-shaped movement; specifically, the housing 1 is composed of two parts, each part is provided with two arc-shaped grooves 102, the two arc-shaped grooves 102 are correspondingly arranged, the arc-shaped slider 6 is adapted to the arc-shaped grooves 102, and the front and rear ends of the arc-shaped slider 6 are respectively fitted in the two arc-shaped grooves 102, and the arc-shaped slider 6 can move along the arc of the arc-shaped grooves 102; a lower jaw pad 5 is provided on the arc-shaped slider 6, the lower jaw pad 5 passes through the housing 1, and the upper jaw pad 4 and the lower jaw pad 5 can be made of silicone or other materials.

[0031] An adjusting seat 2 is movably disposed on the housing 1. One end of the adjusting seat 2 is rotatably disposed on the housing 1 via a rotating shaft or a pin. Specifically, the adjusting seat 2 can be rotated by rotating a shaft on the housing 1 and fixedly sleeved on the outside of the shaft; or a pin can be fixed inside the housing 1 and the adjusting seat 2 can be movably sleeved on the outside of the pin, allowing the adjusting seat 2 to rotate along the pin. The above are all existing technologies and will not be described in detail.

[0032] The rehabilitation mouth opener also includes a linkage assembly 3, which connects the adjustment seat 2 and the arc-shaped slider 6.

[0033] The connecting rod assembly 3 includes a connecting rod 301, one end of which is fixedly provided with a connecting post 302, and the connecting rod 301 is fixedly sleeved on the outside of the connecting post 302; the other end of the connecting rod 301 is provided with a fixing post 303, which is fitted on the arc-shaped slider 6, and the connecting post 302 is fitted on the adjusting seat 2.

[0034] The adjusting seat 2 consists of two identical parts that can be connected by snaps or screws. A groove 202 is provided in the middle of the adjusting seat 2, and multiple limiting holes 201 are evenly distributed on the adjusting seat 2, connecting the limiting holes 201 to the groove 202. A connecting post 302 is fitted into one of the limiting holes 201, allowing the connecting post 302 to rotate within the limiting hole 201. Simultaneously, two retaining rings 304 are fixedly sleeved on the outside of the connecting post 302, contacting the adjusting seat 2 to limit the movement of the connecting post 302. Since the adjusting seat 2 is composed of two identical parts that can be separated, the connecting post 302 can be easily fitted into different limiting holes 201.

[0035] An opening is provided in the middle of the arc-shaped slider 6, through which the connecting rod 301 passes; multiple fixing holes 601 are evenly distributed on the arc-shaped slider 6, and the fixing post 303 is fitted into one of the fixing holes 601; the arc-shaped slider 6 can be made of materials such as silicone, and can undergo elastic deformation by applying external force; since the arc-shaped slider 6 can be elastically deformed, the fixing post 303 can be easily fitted into different fixing holes 601 by bending the arc-shaped slider 6; the fixing hole 601 and the fixing post 303 are adapted to each other, and the fixing post 303 can rotate within the fixing hole 601.

[0036] like Figure 2 As shown, an elastic element 7 is provided between the bottom of the adjusting seat 2 and the inner wall of one side of the housing 1. The elastic element 7 can be a spring 701. The adjusting seat 2 is provided with a through hole structure, and a part of the spring 701 is located inside the through hole structure.

[0037] In this embodiment, when in use, the patient bites on the maxillary pad 4 and the mandibular pad 5. By pressing the adjusting seat 2, the adjusting seat 2 rotates, and the adjusting seat 2 drives the connecting rod 301 to move, thereby driving the arc-shaped slider 6 to move along the arc-shaped groove 102, and the mandibular pad 5 moves away from the maxillary pad 4, thereby expanding the patient's mouth. When the adjusting seat 2 is pressed down, the spring 701 is compressed. After the adjusting seat 2 is rotated to a suitable angle, the adjusting seat 2 is released. Under the action of the spring 701, the adjusting seat 2 can be reset, thereby resetting the mandibular pad 5.

[0038] In this embodiment, by fitting the connecting post 302 into different limiting holes 201, or fitting the fixing post 303 into different fixing holes 601, when the pressing adjustment seat 2 rotates by the same angle, the included angle between the mandibular pad 5 and the maxillary pad 4 can be different, thereby achieving adjustability and making it convenient to use.

[0039] Example 2

[0040] Please see Figure 2 and Figure 7 Based on Embodiment 1, this embodiment provides a blocking part 103 on the housing 1. The blocking part 103 is used to prevent the arc-shaped slider 6 from moving from the arc-shaped groove 102, thereby preventing the arc-shaped slider 6 from detaching from the housing 1.

[0041] Example 3

[0042] Please see Figures 1-9 Based on Embodiment 2, this embodiment further includes a limiting component 8, which limits the rotation of the adjusting seat 2. The limiting component 8 includes a limiting screw 801, which is threadedly connected to the housing 1. Specifically, a threaded hole 101 adapted to the limiting screw 801 is provided on the housing 1, and the limiting screw 801 is engaged in the threaded hole 101. The limiting screw 801 is rotatably mounted on the housing 1 near the adjusting seat 2. When the adjusting seat 2 rotates and contacts the limiting screw 801, the limiting screw 801 can prevent the adjusting seat 2 from continuing to rotate. This is the maximum opening of the patient's mouth. By adjusting the position of the limiting screw 801, the maximum opening of the patient's mouth can be adjusted to meet different usage needs.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
