Description

Technical Field

[0001] The utility model relates to the field of oral teaching models, and more specifically to a portable loose-tooth fixed oral teaching model. Background Art

[0002] At present, in the teaching of oral tooth models, tooth models can be used as intuitive teaching aids to teach dental care knowledge, thereby deepening students' understanding of tooth structure and the significance of dental care. They are almost all made of silicone rubber.

[0003] Chinese patent authorization announcement number: CN211124655U, provides a detachable tooth model for oral experimental teaching. This patent allows the teeth of the teaching tooth model to be detached by designing the jawbone skeleton, alveolar teeth, teeth, base, support rod, and adjustment rod, providing students with physical operations on teeth or jaw components through dental instruments, so that students can correctly learn dental anatomy and related technologies; and the model can be fixedly supported on a desk or teaching stand, freeing the hands of teaching staff, allowing teaching staff to operate other teaching tools, thereby improving teaching quality and allowing students to better understand teaching content; each tooth and the gum corresponding to the tooth are numbered, allowing teaching staff to teach according to the number, and when the tooth is pulled out, allowing beginners to quickly put the tooth back into the gum that matches the tooth.

[0004] In the existing technology, dental students need to perform simulated operations through oral teaching models, but in the existing oral loose tooth fixed oral teaching models, it is impossible to select loose teeth, which results in that medical students cannot fully operate on loose teeth in different positions in the real oral cavity, thereby reducing the operation training quality of the teaching model. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a portable loose tooth fixed oral teaching model, which can achieve the fixation and looseness control of the teeth by fixing a limit block at the bottom of the teeth and installing a limit assembly and a control rod at the bottom of the wall that fixes the teeth, and controlling the limit assembly through the control rod to fix and separate the limit block at the bottom of the teeth, thereby allowing medical students to automatically select loose teeth in different positions for simulated training. This structure can effectively improve the practicality and functionality of the oral teaching model and improve the quality of teaching operations.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A portable loose-tooth fixed oral teaching model comprises a lower oral base and an upper oral base, wherein the upper oral base is located at the upper end of the lower oral base, and the lower oral base and the upper oral base are fixedly hinged, and simulated gums are fixedly installed on the inner sides of the lower oral base and the upper oral base, and a plurality of cavities are arranged inside the simulated gums, and a rotating shaft is fixedly installed inside the cavity, and teeth are rotatably installed on the outer side of the rotating shaft, and a limiting block is fixedly installed on one end of the tooth close to the rotating shaft.

[0010] Furthermore, a limiting assembly is fixedly installed at one end of the cavity away from the teeth, and the limiting assembly includes a telescopic rod, a spring and abutment block. The telescopic rod is installed at the end of the cavity away from the teeth by a fixed connection method, the spring is sleeved on the outside of the telescopic rod, and the abutment block is installed at the end of the telescopic rod close to the teeth by a fixed connection method. A slot is provided in the middle of the end of the abutment block close to the teeth, and the slot is adapted to the shape of the limiting block.

[0011] Furthermore, a plurality of control rods are movably inserted into the outer sides of the cavities, the control rods are vertically arranged with the teeth, a bearing is fixedly embedded in the middle part of the outer side of the control rod, a connecting rod is fixedly installed inside the bearing, a threaded connection cover is fixedly installed on the end of the connecting rod away from the bearing, a plurality of threaded connection rings are fixedly installed on the outer sides of the lower oral base and the upper oral base, the threaded connection rings are all arranged on the outer sides of the control rods, and the threaded connection rings are threadedly connected to the threaded connection covers, a first inclined surface is arranged at the bottom of one end of the control rod close to the limit assembly, the first inclined surface is inclined with the left lower and the right higher, a plurality of abutment blocks are provided with sockets inside, the lower ends of the sockets are inclined with the left lower and the right higher, and the control rods are movably inserted into the sockets.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) This solution can be achieved by fixing a limit block at the bottom of the tooth, and installing a limit assembly and a control rod at the bottom of the wall that fixes the tooth. The limit block at the bottom of the tooth can be fixed and separated by the control rod to control the limit assembly, thereby achieving control over the fixation and loosening of the tooth. Medical students can then automatically select loose teeth at different positions for simulation training. This structure can effectively improve the practicality and functionality of the oral teaching model and improve the quality of teaching operations.

[0015] (2) In the default state, the spring stretches and pushes the abutment block to move toward the end close to the tooth, so that the limit block at the lower end of the tooth is inserted into the groove on the surface of the abutment block. The abutment block is supported by the spring, so that the tooth can be stably limited.

[0016] (3) The teaching staff can manually squeeze the control rod to move it toward one end close to the abutment block. The movement of the control rod can push the abutment block downward, causing the limit block to disengage from the slot. Then, the threaded connection cover on the outside of the control rod is rotated to thread the threaded connection cover and the threaded connection ring to fix the control rod. At this time, the tooth is in a loose state, which is convenient for medical students to fix the loose tooth. BRIEF DESCRIPTION OF THE DRAWINGS
