DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 5As shown, a denture simulation fixing frame includes a support frame 1, a denture opening and closing adjustment mechanism 4 installed on one side of the support frame 1, a denture fixing plate 7 connected to the denture opening and closing adjustment mechanism 4, and a denture model 5 connected to the surface of the denture fixing plate 7. The support frame 1 is composed of two symmetrical L-shaped brackets, a support plate 101 is fixedly connected between the bottoms of the two L-shaped brackets, a fixing plate 104 is fixedly connected between the tops of the two L-shaped brackets, a rotating component 2 is rotatably connected between the support plate 101 and the fixing plate 104, and the rotating component 2 includes a rotating rod 201 and a rotating disk 202. The top of the support plate 101 is provided with a circular Groove 102, an end bearing 103 is fixedly connected to the bottom of the circular groove 102, a rotating rod 201 is fixedly connected to the inner ring of the end bearing 103, a through hole 105 is opened on the top of the fixed plate 104, and a turntable 202 is fixedly connected to the other end of the rotating rod 201 through the through hole 105, and threads are provided on the upper and lower ends of the rotating rod 201, and the threads of the upper and lower ends are arranged in opposite directions. A symmetrical height adjustment mechanism 3 is sleeved on the outer side of the rotating rod 201, and the symmetrical height adjustment mechanism 3 is respectively sleeved on the upper and lower ends of the rotating rod 201, and one end of the height adjustment mechanism 3 is fixedly connected to a denture opening and closing adjustment mechanism 4.

[0023] like Figure 1 As shown, a denture simulation fixing frame in the utility model is similar to the existing denture simulation fixing frame structure, such as the denture simulation fixing frame disclosed in the patent publication number CN210749586U. The main improvement of the utility model is to improve the adaptability of the denture simulation fixing frame, such as Figures 1 to 5 As shown, when a denture simulation fixing frame in the utility model is in use, the rotating component 2 drives the height adjustment mechanism 3 connected to its outer side to move up and down, and drives the denture opening and closing adjustment mechanism 4 connected to the height adjustment mechanism 3 to adjust the height of the upper and lower jaws in the mouth. The denture opening and closing adjustment mechanism 4 can make the denture models 5 connected to it detect the bite force, and the denture opening and closing adjustment mechanism 4 can be moved to make the denture models 5 bite or separate; the upper and lower ends of the rotating rod 201 are arranged with opposite threads so that when the height adjustment mechanism 3 rotates with the rotating rod 201, the user can move the two height adjustment mechanisms 3 closer to or farther away from each other by rotating the turntable 202, so as to achieve the effect of adjusting the height of the upper and lower jaws in the mouth. At the same time, the circular groove 102 of the support plate 101 and the through hole 105 of the fixing plate 104 can fix the rotating rod 201 between the supporting frame 1, and at the same time, the cooperation of the rotating rod 201 and the end bearing 103 can make the rotating rod 201 rotate between the supporting frame 1 to adjust the height of the upper and lower jaws in the mouth.

[0024] like Figure 3 to Figure 4As shown, the height adjustment mechanism 3 includes a sliding bar 301, a connecting plate 302 and a spring 303. A rotating rod channel 304 threadedly connected to the rotating rod 201 is opened at the top of the sliding bar 301. The connecting plate 302 is fixedly connected to one end of the sliding bar 301, and a spring 303 is fixedly connected between two symmetrical connecting bars.

[0025] Specifically, through this arrangement, when the rotating component 2 drives the height adjustment mechanism 3 to adjust the height, the spring 303 can prevent the sliding bar 301 threadedly connected to the rotating rod 201 from being skewed when the rotating rod 201 rotates, thereby affecting the denture detection effect. At the same time, the sliding bar 301 drives the denture opening and closing adjustment mechanism 4 connected to it to move up and down, thereby achieving the effect of adjusting the height of the upper and lower jaws in the oral cavity.

[0026] like Figures 3 to 5 As shown, the denture opening and closing degree adjustment mechanism 4 includes a fixed sleeve 401, a bearing 402, a rotating column 403 and a denture support plate 406, one end of the connecting plate 302 is fixedly connected to two symmetrical fixed sleeves 401, the inner bottom of the fixed sleeve 401 is fixedly connected to the bearing 402, the rotating column 403 is fixedly connected between the symmetrical bearings 402, the inner ring of the bearing 402 is fixedly connected to the outer side of the rotating column 403, and the outer side of the rotating column 403 is fixedly connected to the denture support plate 406.

[0027] Specifically, through this arrangement, when the user moves the denture support plate 406, the denture support plate 406 drives the rotating column 403 connected thereto to rotate in two symmetrical bearings 402, thereby achieving the effect of adjusting the occlusal angle of the denture model 5. The user can adjust the height between the upper and lower jaws. At the same time, when adjusting the occlusal angle, the bite force detection effect of the denture model 5 can be achieved.

[0028] As shown Figures 3 to 5 As shown, a limiting plate 405 is fixedly connected to the inner wall of the fixed sleeve 401, the number of limiting plates 405 is greater than 1, and they are arranged at equal intervals on the top, and a soft silicone pick 404 is fixedly connected to the outer side of the rotating column 403, and the surface of the soft silicone pick 404 is fit and connected to one side of the limiting plate 405.

[0029] Specifically, through this arrangement, when the user bends the denture support plate 406, the soft silicone paddle 404 on the outside of the rotating column 403 is squeezed by the limiting plate 405, and moves from one end of the limiting plate 405 to another end of the adjacent limiting plate 405. Through the engagement of the soft silicone paddle 404 and the limiting plate 405, the user can fix the denture support plate 406 at different angles to perform denture bite force detection, thereby improving the convenience of the denture simulation fixator.

[0030] like Figures 1 to 5 As shown, a denture fixing plate 7 is fixedly connected to the surface of the denture supporting plate 406 .

[0031] Specifically, by setting the denture fixing plate 7 between two symmetrical denture support plates 406, different denture models 5 can be fixed on its surface for testing, and the denture support plate 406 connected thereto drives the denture fixing plate 7 and the denture model 5 to adjust the height and angle, which is convenient for users to test the denture and improves the convenience of the denture simulation fixing frame.

[0032] like Figure 1 As shown, a suction cup 6 is fixedly connected to the bottom of the support frame 1.

[0033] Specifically, by configuring the suction cup 6 in this way, the friction between the support frame 1 and objects such as the desktop can be increased, thereby preventing the denture simulation fixed frame from shaking during the test and affecting the test results.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
