Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 - Figure 2The utility model provides an embodiment: a track-type oral CT device, including an oral CT device 1, a support frame 2 is arranged on the front surface of the oral CT device 1, and an articulator 3 is arranged on the front end of the upper surface of the support frame 2. When the patient is tested, he needs to bite on the articulator 3, which can ensure the stability of the patient's head and improve the clarity of the imaging. The front end outer wall of the articulator 3 is sleeved with an articulator sleeve 6, and the upper surface of the support frame 2 is adjacent to the front side of the articulator 3. A through groove 7 is opened, and a sleeve removal component 4 is arranged on the inner wall of the front end of the support frame 2. The upper surface of the articulator 3 is provided with a A fixing component 5 is provided, and the sleeve removal component 4 includes a movable shell 41, which is slidably connected to the inner wall of the front end of the support frame 2, and a spring 45 is fixedly connected to the rear surface of the movable shell 41. The spring 45 always pulls the movable shell 41 to move backward by its own elasticity, ensuring that the movable shell 41 is always in a closed state when the rectangular bar 46 is not pushed, thereby ensuring the sealing performance. The rear end of the spring 45 is fixedly connected to the inner wall of the front end of the support frame 2, and the upper surface of the front end of the movable shell 41 is fixedly connected to a support plate 8. The patient can put his chin on the support plate 8 to ensure the stability of his head.

[0031] Reference Figure 1 , Figure 3 The fixing assembly 5 includes a bracket 51, which is fixedly connected to the rear end of the upper surface of the articulator 3. The inner wall of the front end of the bracket 51 is fixedly connected with a concave shell 55, and the inner wall of the concave shell 55 is slidably connected with an extrusion block 54. The extrusion block 54 is trapezoidal in shape, and the front surface and the rear surface are provided with inclined surfaces. The inclined surfaces are provided to facilitate the installation and removal of the articulator sleeve 6, thereby improving the work efficiency. The rubber material is provided on the lower surface of the extrusion block 54. Under the action of the spring 2 53, the rubber material can be deformed when it contacts the articulator sleeve 6, thereby increasing the contact area and improving the stability of the articulator sleeve 6.

[0032] Reference Figure 1 - Figure 2 The sleeve removal assembly 4 also includes a rectangular bar 46, the bottom end of the rectangular bar 46 is slidably connected to the inner wall of the through groove 7, the lower surface of the through groove 7 is fixedly connected to the upper surface of the rear end of the movable shell 41, and the upper surface of the rectangular bar 46 is fixedly connected to a top block 47. The top block 47 is L-shaped to ensure that it can smoothly eject the bite sleeve 6, thereby improving practicality. The top block 47 is slidably connected to the inner wall of the articulator 3.

[0033] Reference Figure 2 The sleeve assembly 4 also includes a storage box 42, which slides on the inner wall of the movable shell 41. A card block 43 is fixedly connected to the right surface of the front end of the storage box 42. The card block 43 is made of rubber material and has a certain elasticity. It will deform when squeezed and will quickly reset when the squeezing is released. A card slot 44 is opened on the inner wall of the front end of the movable shell 41, and the card block 43 contacts the inner wall of the card slot 44.

[0034] Reference Figure 3 A pull rod 52 is slidably connected to the upper surface of the concave shell 55, and a spring 53 is sleeved on the outer wall of the pull rod 52. The spring 53 always pushes the extrusion block 54 to move downward through its own elasticity to ensure the stability of its clamping of the bite sleeve 6. One end of the spring 53 is fixedly connected to the inner wall of the concave shell 55. The concave shell 55 ensures the stability of the movement of the extrusion block 54. The other end of the spring 53 is fixedly connected to the upper surface of the extrusion block 54.

[0035] Working principle: During use, when the bite sleeve 6 needs to be put on, it is only necessary to pass the bite sleeve 6 from the front side of the top of the bite frame 3 through the outer wall of the support frame 2. During the insertion process, the bite sleeve 6 will contact the extrusion block 54 and push it upward along the inclined surface of the extrusion block 54. The extrusion block 54 will squeeze the spring 2 53 upward until the upper surface of the bite sleeve 6 contacts the lower surface of the extrusion block 54, and then the pushing can be stopped. At this time, the spring 2 53 will always push the extrusion block 54 to move downward through its own elasticity. Since the lower surface of the extrusion block 54 is made of rubber and has a certain degree of roughness, the bite sleeve 6 can be fixed to prevent it from falling off during use, thereby improving stability. At this time, the patient can bite the bite sleeve 6 and place the chin on the upper surface of the support plate 8, so that the device can be started for inspection.

[0036] When the patient has finished using the device and needs to take off the bite sleeve 6, he only needs to pull the rectangular bar 46, which will drive the top block 47 to slide on the inner wall of the articulator 3. The top block 47 will contact the rear surface of the extrusion block 54 and push the extrusion block 54 to move along the inclination of its rear surface, so that the extrusion block 54 releases the clamping and fixation of the bite sleeve 6. At the same time, the top block 47 contacts the bite sleeve 6 and pushes the bite sleeve 6 to move and separate from the outer wall of the articulator 3. While the top block 47 pushes the bite sleeve 6, the rectangular bar 46 will also drive the movable shell 41 to move and open it. The movable shell 41 will stretch the spring 1 45, so that when the bite sleeve 6 separates from the outer wall of the articulator 3, it will fall into the inner wall of the storage box 42 arranged on the inner wall of the movable shell 41. In this way, the used bite sleeves 6 can be collected and collected. After removing the sleeve, just loosen the rectangular bar 46. At this time, the spring 1 45 will drive the movable shell 41 to move in the opposite direction through its own elasticity to close it, thereby improving the installation performance.

[0037] When it is necessary to deal with the discarded engaging sleeve 6 inside the storage box 42, it is only necessary to pull the storage box 42. While pulling the storage box 42, another hand is required to press the movable shell 41 to prevent the movable shell 41 from opening. At this time, the card block 43 will move together with the storage box 42, and the card block 43 will be squeezed and deformed and separated from the inner wall of the card slot 44, so that the storage box 42 can be taken out from the inner wall of the movable shell 41. When installing, just insert the storage box 42 into the inner wall of the movable shell 41. The subsequent operation method is the same as above, and the matching method between the structures is also the same as above.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
