[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] At present, all oral articulators are fixed with a rod, and the fixed angle of the rod and the oral articulator cannot be adjusted. Therefore, when trainees are trained, the actual human surgical environment cannot be truly restored. Therefore, it is extremely necessary to design a gear universal joint with an angle adjustment for an oral teaching simulation trainer to simulate a more realistic surgical environment and improve the training effect.

[0023] Combination Figure 1 As shown: a gear universal joint for angle adjustment of an oral teaching simulation trainer, comprising an adjusting shaft sleeve 100, and an adjusting shaft mechanism 200 and a limiting mechanism 300 assembled integrally with the adjusting shaft sleeve 100.

[0024] Specifically, the adjustment shaft mechanism 200 is connected to the oral frame, and the adjustment shaft mechanism 200 can adjust the shaft sleeve 100 as the axis to rotate at a certain angle, thereby driving the oral frame to rotate at a certain angle; specifically, it drives the pitch angle adjustment of the oral frame; wherein, the limiting mechanism 300 is used for limiting and releasing the adjustment shaft mechanism 200, when released, the adjustment shaft mechanism 200 can adjust the angle; when limited, the adjustment shaft mechanism 200 can fix the current angle position.

[0025] Combination Figure 1-Figure 5 As shown: the adjusting sleeve 100 includes a sleeve cover 110 disposed at the top, the sleeve cover 110 is provided with a cover groove 120, the side wall of the adjusting sleeve 100 is provided with a sleeve groove 130, a screw hole 140 and a limit mechanism jack 150; the adjusting shaft mechanism 200 includes an adjusting body 210 disposed inside the adjusting sleeve 100, the adjusting body 210 is connected to an adjusting shaft 220, the side end of the adjusting body 210 is provided with an adjusting body tooth 230, and the inside of the adjusting body 210 is provided with a screw hole 140. An adjusting body through hole 240 is provided through it; the limiting mechanism 300 includes a limiting body 310 inserted into the adjusting sleeve 100, a connecting block 320 threadedly connected to the limiting body 310, and a handshake 340 provided at one end of the connecting block 320, and the limiting body 310 is inserted into the limiting mechanism jack 150; the cover groove 120 and the sleeve groove 130 are connected to each other, and the adjusting shaft 220 can rotate in the cover groove 120 and the sleeve groove 130.

[0026] Specifically, the cover groove 120 and the shaft sleeve groove 130 are used to provide a rotation space for the adjustment shaft 220 , and therefore, the cover groove 120 and the shaft sleeve groove 130 are connected to each other, that is, the cover groove 120 and the shaft sleeve groove 130 are in the same axial section.

[0027] The limiting body 310 is provided with a pin hole 311, and the side end of the limiting body 310 is provided with a limiting body tooth 312. The outer edge of the limiting body 310 is provided with a limiting body thread 313. The pin hole 311 is provided with a pin 330 inserted through a spring 331. The limiting body thread 313 is internally threadedly connected to the connecting block 320; one end of the pin 330 is provided with a pin hole 332, and the screw hole 140 is provided with a screw 160, and the screw 160 is connected to the connecting block 320. The pin hole 332 is threadedly locked; the limiting body teeth 312 and the adjusting body teeth 230 are meshed and transmission-connected with each other; a limiting protrusion 314 is provided on the limiting body 310, and a limiting hole 170 is provided on the limiting mechanism socket 150, and the limiting protrusion 314 and the limiting hole 170 are mutually engaged and limited; the limiting mechanism socket 150, the adjusting body through hole 240, the screw hole 140, the pin hole 332 and the pin hole 311 are all on the same axis.

[0028] The adjusting shaft mechanism 200 and the limiting mechanism 300 are connected by meshing of teeth. Specifically, the adjusting body teeth 230 and the limiting body teeth 312 are meshed with each other.

[0029] Specifically, the limiting body 310 is limited in the limiting mechanism insertion hole 150 through the limiting hole 170, so the limiting body 310 can move forward and backward in the limiting mechanism insertion hole 150, but cannot rotate left and right.

[0030] Specifically, the forward and backward movement of the limiting body 310 causes the limiting body teeth 312 and the adjusting body teeth 230 to separate from each other; after the teeth are separated from each other, since the adjusting shaft structure no longer has the limiting effect of the limiting body teeth, the adjusting shaft mechanism 200 can rotate, thereby adjusting the angle of the adjusting shaft 220.

[0031] Specifically, after the limit body 310 is separated from the adjusting shaft mechanism 200, the pin 330 is always locked with the screw 160, and the position of the pin 330 remains unchanged; during the separation process of the limit body 310 from the adjusting shaft mechanism 200, the spring 331 will be squeezed. After adjusting the angle of the rear adjusting shaft 220, release your hand. Under the action of the spring, the limit body 310 is reset, and the limit body teeth 312 re-engage with the adjusting body teeth 230 and are limited to this angle.

[0032] Specifically, the pin 330 passes through the pin hole 311 and the adjusting body through hole 240 , so when the adjusting body 210 rotates, it rotates with the pin 330 as the axis.

[0033] Specifically, the handshake 340 is used to pull the limiting body 310, wherein the movable cavity 400 allows a certain movable space inside, so that the limiting body 310 can be inserted and removed smoothly.

[0034] 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.
