Description

Technical Field

[0001] This utility model specifically relates to a portable oral teaching tool, belonging to the technical field of oral teaching tools. Background Technology

[0002] In the field of oral medicine education, traditional teaching methods often rely on large clinics or equipment facilities, which greatly limits the breadth and flexibility of teaching, especially in areas with relatively insufficient oral medical resources. Although current oral teaching props have made significant progress in precision and functionality, most of them are designed to be large in size and not easy to carry and store, which causes inconvenience to teachers and students and limits the scope of teaching activities.

[0003] Current dental teaching aids have certain limitations in structural design. Most teaching aids do not use flexible materials to make dental models with special shapes and colors, which makes the teaching equipment inconvenient to transport and carry. Especially when teaching dental artificial teeth and force analysis, it is difficult to flexibly adjust the shape and color of the teaching aids according to the specific patient cases of the trainees, thus affecting the teaching effect and the flexibility of practical application. In addition, existing dental teaching aids are usually large in size, inconvenient to carry, and limited by space and region, making it impossible to conduct effective teaching in some specific environments.

[0004] To address the aforementioned technical issues, a portable oral teaching tool has been proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a portable oral teaching tool that facilitates efficient explanation of dental biomechanics analysis, allows for quick and precise explanation of different patient cases using various arrangement methods, and is easy to store and carry.

[0006] A portable oral teaching tool includes a support mechanism and a display mechanism. The support mechanism includes a base and a U-shaped frame. The top of the base is symmetrically threaded with a first support rod, and the top of the first support rod is engaged with a second support rod. The U-shaped frame is engaged with the second support rod. The bottom of the base is symmetrically integrally formed with storage grooves. The bottom of the base is provided with a base plate, and the interior of the base has two storage holes.

[0007] The display mechanism includes a flexible magnetic whiteboard and magnetic teaching aids. A rotating shaft is rotatably installed inside the base. Torsion springs are fixedly connected to both sides of the rotating shaft. One end of each torsion spring is fixedly connected to the base. The flexible magnetic whiteboard is wrapped around the outside of the rotating shaft. One side of the flexible magnetic whiteboard is fixedly connected to the rotating shaft. The magnetic teaching aid is located on one side of the flexible magnetic whiteboard. Teaching aid components are provided on one side of the magnetic teaching aid. A limiting plate is fixedly connected to the top of the flexible magnetic whiteboard. A hook is fixedly connected to the top of the limiting plate. The hook engages with a U-shaped frame.

[0008] Furthermore, the magnetic teaching aid and its components are all composed of a printed surface and a magnetic sheet, with the printed surface fixedly connected to one side of the magnetic sheet.

[0009] Furthermore, a magnetic strip is provided on one side of the teaching aid component.

[0010] Furthermore, the interior of each of the two storage holes is provided with a dust cover and a storage tube, a handle is fixedly connected to one side of the storage tube, and two identification plates are fixedly connected to one side of the base.

[0011] Furthermore, an anti-slip pad is fixedly connected to the bottom of the base plate.

[0012] Furthermore, the base plate is internally connected with symmetrical threaded fixing bolts, one end of which is threadedly connected to the base.

[0013] Beneficial effects:

[0014] This invention uses a first and second support rod in conjunction with a U-shaped frame as the overall support framework. A flexible magnetic whiteboard is unfolded and fixed within the frame using hooks. Magnetic teaching aids representing different functions, along with their components, visually demonstrate teaching cases, facilitating efficient explanations of dental prosthetics and biomechanical analysis. Different arrangements allow for quick and precise explanations tailored to different patient cases. All magnetic teaching aids and components are lightweight and can be quickly stored in the base for easy transport and use in various regions and environments. Attached Figure Description
