AI Technical Summary
The sphere in the traditional oral occlusion frame model cannot fix the current rotation angle, which makes it impossible to truly simulate the rotation characteristics of the human neck during training and teaching, affecting the teaching effect.
A directional universal joint of an oral teaching simulation trainer was designed. By opening a notch at the side end of the sphere and setting screw holes and screws at the upper side end, the horizontal rotation of the sphere is achieved by 180 degrees and up and down 90 degrees, which is in line with the ergonomics.
Through the design of the directional universal joint, the sphere can lock the current angle and adjust the rotation angle and amplitude, improving the authenticity and effect of teaching and training.

Abstract
Description
Technical Field
[0001] The invention discloses a directional universal joint for adjusting the angle of an oral teaching simulation trainer. Background Art
[0002] The teaching of stomatology has high requirements for operability. Learners need to undergo professional surgical training to master basic surgical skills, so practical operation is an indispensable part of teaching. Therefore, oral articulator models are widely used in simulated surgical operations in stomatological schools or stomatological hospitals.
[0003] The current oral articulator is connected by a support rod, and the connecting end of the oral articulator and the support rod is connected by a sphere to simulate the rotation of the human neck. The traditional sphere is a complete sphere. During training and teaching, the sphere rotates 360 degrees and the current rotation angle cannot be fixed, which is not in line with the ergonomics of the human neck. Therefore, it is extremely necessary to design a directional universal joint for angle adjustment of an oral teaching simulation trainer. Utility Model Content
[0004] In view of the above technical deficiencies, the utility model provides a directional universal joint for adjusting the angle of an oral teaching simulation trainer.
[0005] In order to achieve the above object, the utility model is implemented through the following technical solutions:
[0006] A directional universal joint for adjusting the angle of an oral teaching simulation trainer comprises an upper sleeve and a lower sleeve which are threadedly connected to each other, a top ring is provided at the top of the upper sleeve, a base is provided at the bottom of the lower sleeve, a sphere is rotatably arranged between the top ring and the base, a notch is provided at the side end of the sphere, a screw hole is provided at the side end of the upper sleeve, and a through hole is provided inside the sphere.
[0007] Furthermore, the notch is opened along the circumference of the sphere.
[0008] Furthermore, the slot and the screw hole are positioned opposite to each other, the screw hole is threadedly connected with a screw, and the screw is placed within the opening range of the slot.
[0009] Furthermore, the bottom of the base is an arc-shaped concave cavity downwards and fits tightly with the bottom of the sphere.
[0010] Furthermore, the through hole is connected to the oral articulator via a connecting rod.
[0011] The beneficial effects of the utility model are as follows: the sphere is provided with a notch, and the notch and the screw cooperate with each other, so that the sphere can be rotated 180 degrees horizontally and 90 degrees vertically, which conforms to the human neck ergonomics and improves the training effect of teaching.

[0018] Combination Figure 1-5 As shown: a directional universal joint for angle adjustment of an oral teaching simulation trainer, an upper sleeve and a lower sleeve threadedly connected to each other, a top ring is provided on the upper part of the upper sleeve, a base is provided on the lower part of the lower sleeve, a sphere is rotatably arranged between the top ring and the base, a notch is provided on the side end of the sphere, a screw hole is provided on the side end of the upper sleeve, and a through hole is provided inside the sphere.
[0019] The notch is opened along the periphery of the sphere, and the inner wall of the notch is arched; the notch and the screw hole are opposite to each other, the screw hole is threaded with a screw, and the screw is placed within the opening range of the notch; the bottom of the base is an arc-shaped concave cavity downward, and is tightly fitted with the bottom of the sphere.; The through hole is connected to the oral articulator through a connecting rod.
[0020] Specifically, the traditional sphere has no grooves and is a complete sphere. The traditional sphere can rotate 360 degrees in the horizontal plane, which does not conform to the ergonomics of the human neck and cannot simulate teaching and training more realistically.
[0021] Specifically, the notch 6 is an arched protrusion, or the notch 6 is a planar groove. Preferably, the notch 6 is an arched protrusion.
[0022] Specifically, after the slot 6 is opened, one end of the screw 8 can abut against the bottom of the slot 6 to lock the sphere 5 , that is, to lock the current angle of the sphere 5 .
[0023] Specifically, the rotation angle and rotation amplitude of the sphere 5 are adjusted by the tightening depth of the screw 8 in the screw hole.
[0024] Specifically, the screw 8 is always kept within the opening range of the notch 6 to ensure that the notch 6 is always opposite to the screw 8 .
[0025] Specifically, the slotting range of the notch 6 affects the rotation range of the ball 5. Preferably, the notch is made so that the ball 5 can rotate 180 degrees horizontally and 9 degrees vertically. This angle is more in line with human neck ergonomics.
[0026] Specifically, the through hole 9 is used for connection with an oral articulator.
[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
