[0023] Example 1
[0024] like Figures 1-4 As shown, this utility model provides an opening training device, including a fixing mechanism 1. The top surface of the fixing mechanism 1 is provided with a spreading mechanism 2. The spreading mechanism 2 includes a hinge 21, which is movably connected to one end of the outer surface of the fixing mechanism 1. A support plate 22 is fixedly connected to the side of the hinge 21. A rubber pad 23 is fixedly connected to the top surface of the support plate 22. An anti-slip groove 24 is provided inside the top surface of the rubber pad 23. An extension plate 25 is fixedly connected to the side of the support plate 22. A connecting plate 26 is fixedly connected to the side of the extension plate 25. A limit device 28 is fixedly connected to one end of the side of the extension plate 25. An arc-shaped slide rod 27 is fixedly connected to the bottom surface of the extension plate 25. A base plate 210 is fixedly connected to the bottom surface of the arc-shaped slide rod 27. A spring 29 is movably connected to the top end of the outer surface of the arc-shaped slide rod 27. A stroke adjustment bolt 211 is threadedly connected to the bottom end of the outer surface of the arc-shaped slide rod 27.
[0025] In this embodiment, by inserting the entire device in its contracted state into the patient's mouth and turning the stroke adjustment bolt 211 downwards, the entire device can be slowly opened in the patient's mouth through the cooperation of the spring 29 and the arc-shaped slide rod 27. When it is opened to a state that the patient can tolerate, the stroke adjustment bolt 211 is turned off, so that the patient can bite down on the anti-slip groove 24 to make an anti-movement against the spring 29, which can achieve the effect of exercising the mouth opening.
[0026] Example 2
[0027] like Figures 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the limiting device 28 includes a fixing buckle 281, which is fixedly connected to one side end of the extension plate 25. The fixing buckle 281 is rotatably connected to a rotating ring 282 inside. An arc-shaped rod 283 is fixedly connected to the bottom surface of the rotating ring 282. A support plate 284 is fixedly connected to the bottom side of the arc-shaped rod 283. An anti-slip pad 285 is fixedly connected to the top surface of the support plate 284. The anti-slip pad 285 is movably connected to the bottom surface of the fixing mechanism 1.
[0028] In this embodiment, after the patient's mouth muscles have been fully exercised and become sore, the arc-shaped rod 283 can be moved at the same time as the device is bitten for the last time. The arc-shaped rod 283 rotates around the center of the rotating ring 282, which drives the support plate 284 to bring the bottom surface of the fixing mechanism 1 and releases the biting anti-slip groove 24. The anti-slip pad 285 will tightly grip the bottom surface of the fixing mechanism 1, keeping the device in a closed state, making it easy to remove the device from the patient's mouth.
[0029] Example 3
[0030] like Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing mechanism 1 includes a second hinge 11, a first hinge 21 movably connected inside the second hinge 11, a fixing plate 12 fixedly connected to the side of the second hinge 11, a second rubber pad 13 fixedly connected to the bottom surface of the fixing plate 12, an anti-slip groove 14 formed on the bottom surface of the second rubber pad 13, an extension plate 15 fixedly connected to the side of the fixing plate 12, an arc-shaped sliding groove 110 formed inside the top surface of the extension plate 15, and an arc-shaped sliding rod 27 slidably connected to the arc-shaped sliding groove. Inside 110, the stroke adjustment bolt 211 is tightly attached to the bottom surface of the extension plate 2 15, the anti-slip pad 285 is movably connected to one end of the bottom surface of the extension plate 2 15, the side of the extension plate 2 15 is fixedly connected to the connecting plate 2 16, the inside of the connecting plate 2 16 is movably connected to the screw 18, the outer surface of the screw 18 is threaded with the nut 19, the top surface of the screw 18 is fixedly connected to the arc-shaped spring piece 17, there are two screws 18, the other screw 18 is fixedly connected to the top surface of the arc-shaped spring piece 17 and movably connected to the inside of the connecting plate 1 26.
[0031] In this embodiment, the entire device can be opened around hinges 11 and 21 by the cooperation of hinge 21 and hinge 21. The device is prevented from slipping while protecting the patient's oral cavity by the cooperation of rubber pad 13 and anti-slip groove 14 with rubber pad 23 and anti-slip groove 24. The arc-shaped slide groove 110 and arc-shaped slide rod 27 limit the movement trajectory of the entire device. At the same time, by inserting screws 18 into the connecting plates 26 and 26, the arc-shaped spring piece 17 can be fixed inside the connecting plates 26 and 26, so that the support force of the entire device can be adjusted according to the patient's needs.
[0032] The working principle of this mouth-opening training device will be explained in detail below.
[0033] like Figures 1-4 As shown, by inserting the entire device in its contracted state into the patient's mouth and turning down the stroke adjustment bolt 211, the spring 29 can push the arc-shaped slide rod 27 to slide inside the arc-shaped slide groove 110, causing the entire device to open around hinge 21 and hinge 11. Through the cooperation of rubber pad 213 and anti-slip groove 214 with rubber pad 123 and anti-slip groove 24, the device is prevented from slipping while protecting the patient's oral cavity. When the device is opened to a position that the patient can tolerate, turning the stroke adjustment bolt 211 stops, allowing the patient to bite down on the anti-slip groove 24, creating a counter-movement against the spring 29, thus exercising the mouth opening. Simultaneously, through continuous... A screw 18 is inserted into the inside of the connecting plate 1 (26) and the connecting plate 2 (16), so that the arc-shaped spring piece 17 can be fixed inside the connecting plate 2 (16) and the connecting plate 1 (26). This allows the support force of the entire device to be adjusted according to the patient's needs. After the patient's mouth muscles have been fully exercised and have become sore, the arc-shaped rod 283 can be moved while the device is bitten for the last time. The arc-shaped rod 283 rotates around the center of the rotating ring 282, which drives the support plate 284 to bring the bottom surface of the fixing mechanism 1 and release the biting anti-slip groove 24. The anti-slip pad 285 will tightly grip the bottom surface of the fixing mechanism 1, keeping the device in a closed state, making it easy to remove the device from the patient's mouth.
[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
