[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Figures 1-6 The diagram schematically illustrates the structure of a novel tooth model according to one embodiment of the present invention.

[0025] like Figures 1-6 As shown, a novel tooth model includes an upper jaw 1, a lower jaw 2, and a connecting rod 3. The upper jaw 1 is connected to the lower jaw 2 via the connecting rod 3. Teeth can be formed on both the upper jaw 1 and the lower jaw 2. Through the teeth on the upper jaw 1 and the lower jaw 2 of this invention, students can clearly understand the distribution and structure of human teeth. Figure 2 As can be seen from the figure, the upper jaw 1 in this embodiment has an integrally formed receiving groove 4, and a cover plate 5 can be installed on the receiving groove 4. The cover plate 5 and the receiving groove 4 are detachably connected. Therefore, the cover plate 5 can be closed on the receiving groove 4, or the cover plate 5 can be removed from the receiving groove 4. Generally speaking, the volume of the tooth model is large, so the space of the receiving groove 4 is also large. Some teaching tools can be placed in the receiving groove 4, which is convenient for teachers to carry the teaching tools.

[0026] like Figures 4-6 As shown, multiple connecting posts 51 are integrally formed on the back of the cover plate 5. The connecting posts 51 can be locked onto the upper jaw 1 and form a detachable connection with the upper jaw 1. Figure 1 As can be seen, a recess 11 can be integrally formed on the upper jaw 1. When the cover plate 5 is closed on the upper jaw 1, the recess 11 can provide space for a hand to reach into the receiving groove 4. Therefore, the cover plate 5 can cover the receiving groove 4 to prevent the teaching tools in the receiving groove 4 from falling out, and by setting the recess 11, it is convenient to reach in and open the cover plate 5.

[0027] like Figure 2As shown, on the upper jaw 1, a plurality of posts 7 are integrally formed at corresponding positions in the receiving groove 4. Each post 7 has a receiving slot 71. A connecting post 51 can be inserted into the receiving slot 71 or pulled out of the receiving slot 71. Therefore, the post 7 and the connecting post 51 can form a detachable connection between the cover plate 5 and the upper jaw 1.

[0028] like Figure 5 and Figure 6 As shown, in this embodiment, a groove 52 is integrally formed at the end (i.e., the upper end) of the connecting post 51, and a protrusion 72 is integrally formed at the corresponding position on the inner wall of the post 7. When the protrusion 72 is inserted into the groove 52, the connecting post 51 can be inserted into the post 7; when the protrusion 72 leaves the groove 52, the connecting post 51 can be removed from the post 7. In this embodiment, the post 7 and the connecting post 51 are made of a material with a certain degree of elasticity (such as rubber, silicone, etc.), so when a certain external force is applied, the protrusion 72 can be made to leave the groove 52.

[0029] In this embodiment, there are five connecting posts 51 and five upright posts 7. In other embodiments, the number of connecting posts 51 and five upright posts 7 can be set according to the size of the cover plate 5, such as four connecting posts 51 and four upright posts 7.

[0030] In this embodiment, the process of detachably connecting the cover plate 5 to the upper jaw 1 is as follows: To place the cover plate 5 onto the upper jaw 1, align the connecting post 51 on the back of the cover plate 5 with the receiving slot 71 of the post 7, so that the connecting post 51 enters the receiving slot 71. Then, press the cover plate 5 firmly, so that the groove 52 on the cover plate 5 is locked by the protrusion 72. When removing the cover plate 5 from the upper jaw 1, insert your hand into the recess 11 and pull the cover plate 5 forcefully. Since both the groove 52 and the protrusion 72 are arc-shaped, and both the connecting post 51 and the post 7 on the cover plate 5 can be made of a material with a certain degree of elasticity (such as rubber, silicone, etc.), after pulling the cover plate 5 forcefully, the groove 52 can disengage from the protrusion 72, causing the cover plate 5 and the upper jaw 1 to separate, forming a... Figure 6 The state shown.

[0031] Furthermore, the lower jaw portion 2 in this embodiment is also provided with a receiving groove, and a cover plate is correspondingly provided on the receiving groove of the lower jaw portion 2. The detachable connection method between the lower jaw portion 2 and the cover plate can be exactly the same as the connection structure between the cover plate 5 and the upper jaw portion 1 described above, therefore, it will not be described again.

[0032] like Figures 1-3 As shown, there are two connecting rods 3 in this embodiment, arranged side by side. The two connecting rods 3 make the connection between the upper jaw 1 and the lower jaw 2 more stable.

[0033] In this embodiment, the upper end of the connecting rod 3 can be fixed to the upper jaw 1 by a nut 6, and the lower end of the connecting rod 3 can be fixed to the lower jaw 2 by a nut 6. In this way, the connecting rod 3 can be more firmly fixed to the upper jaw 1 and the lower jaw 2.

[0034] In this embodiment, both the upper jaw 1 and the lower jaw 2 are integrally formed with through holes. The upper end of the connecting rod 3 can be inserted into the through hole of the upper jaw 1 and fixed to the upper jaw 1 by the nut 6. The lower end of the connecting rod 3 can be inserted into the through hole of the lower jaw 2 and fixed to the lower jaw 2 by the nut 6.

[0035] In this invention, both the upper jaw 1 and the lower jaw 2 are formed with receiving grooves, which can be used to store teaching aids for easy storage and are more convenient for teachers. The two ends of the connecting rod 3 are fixed to the upper jaw 1 and the lower jaw 2 respectively with nuts. During use, even if the connecting rod 3 moves or shakes, the nuts will not loosen, making the invention more stable overall.

[0036] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
