Description

Technical Field

[0001] This utility model belongs to the field of dental teaching model technology, and in particular relates to a split soft rubber dental teaching model. Background Technology

[0002] In the field of dental and maxillofacial teaching and training, traditional teaching models often adopt an integrated design. This design makes the model structure monolithic, making it difficult to disassemble and display the internal structure. This brings many inconveniences to students' understanding and actual operation. In particular, when assembling auxiliary equipment such as scanning rods, the limited operating space often leads to a cumbersome and inefficient operation process.

[0003] In addition, most traditional dental models are made of hard materials, such as photosensitive resin and plaster. Although these materials have high hardness and stability, they lack elasticity, which makes it necessary to rely on screws and other fasteners when assembling components such as the scanning rod. The operation process is complicated and the model is easily damaged. Although there are also dental models made of soft rubber materials, the lack of positioning holes and other designs makes components such as the scanning rod easy to fall off after installation, affecting the stability and service life of the model.

[0004] To address the aforementioned issues, some modular dental teaching models have emerged in the existing technology, attempting to improve the flexibility and operability of the models through detachable design. However, these modular models still have many shortcomings in terms of assembly stability and convenience. For example, some models rely on screws or adhesives for fixation, which are cumbersome to disassemble and prone to loosening, affecting the stability and reusability of the models. At the same time, these models often have limited functionality and cannot support the installation of both the maxilla and mandible simultaneously, thus limiting the diversity of teaching scenarios. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a split-type soft rubber dental teaching model.

[0006] To achieve the above objectives, the utility model adopts the following technical solution: a split soft rubber dental teaching model, including a base, a placement platform installed on the base, a pair of fixed seats provided on the placement platform, jaw seats respectively installed between the pair of fixed seats and the surface of the base, a plurality of connecting grooves respectively provided on the opposite side of the pair of jaw seats, scanning rods respectively installed in the plurality of connecting grooves, a face mask installed on the surface of the base, and a snap-fit ​​component provided between the face mask and the base.

[0007] By adopting the above technical solution, the split soft rubber dental teaching model of the present invention achieves a split design by designing a base, a placement platform, a fixing seat, a jaw seat, a connecting groove, a scanning rod, a face mask, and snap-fit ​​components. This facilitates the disassembly and display of the internal structure, especially the detailed structure of the jawbone and teeth.

[0014] Optionally, a pair of positioning holes are provided on the opposite sides of the pair of jaw seats, and the pair of positioning posts are inserted into the pair of positioning holes.

[0015] By adopting the above technical solution, the positioning holes opened on the jaw seat are connected with the positioning pins on the base, realizing the positioning and stable installation of the jaw seat. This design not only simplifies the assembly process, but also improves the stability and durability of the model.

[0016] Optionally, each of the pair of jaw seats has a groove, the thickness of which is adapted to the gap between the pair of fixed seats, and the groove is used in conjunction with the pair of fixed seats.

[0017] By adopting the above technical solution, the groove on the jaw seat is matched with the gap between the fixed seat. This design not only facilitates the installation and disassembly of the jaw seat, but also effectively prevents the jaw seat from loosening or deforming during use, ensuring the accuracy and stability of the model.

[0018] Optionally, the opposite sides of the pair of jaw seats are stepped, and the surface of the steps is inclined.

[0019] By adopting the above technical solution, the opposite side of the jaw seat is designed in a stepped shape, and the stepped surface is inclined.

[0039] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] like Figure 1 As shown in Figure 7, the specific solution of the embodiment is as follows: A split soft rubber dental teaching model includes a base 1, which has a double-layer structure. The double-layer structure enhances the stability and load-bearing capacity of the model and provides a foundation for the installation of the face mask 7. The surface of the base 1 is provided with a pair of positioning posts 101 for the installation of the jaw seat 4. The positioning posts 101 provide an installation position for the jaw seat 4, ensuring the stability and accuracy of the jaw seat 4 on the base 1. A placement platform 2 is installed on the base 1. The placement platform 2 is trapezoidal in shape and is integrally formed with the base 1. The back of the placement platform 2 is concave. The trapezoidal design of the placement platform 2 is not only aesthetically pleasing but also optimizes the placement and display effect of the model. The concave design on the back reduces weight while maintaining the structural rigidity, and the integral design enhances the integrity and stability of the model.

[0042] The placement platform 2 is provided with a pair of fixing seats 3. The pair of fixing seats 3 are installed on the inclined surface of the placement platform 2. The end of the pair of fixing seats 3 away from the placement platform 2 is a flared mouth. The fixing seats 3 enhance the stability of the jaw seat 4 and prevent it from slipping or shifting. The flared mouth design facilitates the installation and removal of the jaw seat 4.

[0043] A jaw seat 4 is installed on the surface of the base 1 between the pair of fixed seats 3. The pair of jaw seats 4 are U-shaped. The U-shaped design simulates the real jaw structure, which is convenient for students to observe and operate. The pair of jaw seats 4 are made of soft rubber material, such as silicone or TPU. The elastic modulus of the soft rubber material is controlled between 0.5MP and 2MP. The control of the elastic modulus ensures that the jaw seat 4 has a certain deformation ability while maintaining shape stability, so as to adapt to different assembly requirements.

[0044] A pair of positioning holes 401 are respectively provided on the opposite sides of the pair of jaw seats 4. A pair of positioning pins 101 are inserted into the pair of positioning holes 401. The cooperation between the positioning holes 401 and the positioning pins 101 realizes the positioning and stable installation of the jaw seats 4. A groove 402 is respectively provided on the pair of jaw seats 4. The thickness of the groove 402 is adapted to the gap between the pair of fixing seats 3. The groove 402 is used in conjunction with the pair of fixing seats 3. The gap between the groove 402 and the fixing seats 3 is adapted to enhance the stability of the jaw seats 4 and prevent them from loosening or deforming during use.

[0045] One of the opposing sides of the pair of jaw supports 4 is stepped, and the surface of the steps is inclined. The stepped and inclined surface design can simulate tooth arrangement at different angles, improving the flexibility and practicality of the model. Each of the opposing sides of the pair of jaw supports 4 is provided with several connecting grooves 5, providing installation positions for scanning rods 6. Each of the several connecting grooves 5 is equipped with a scanning rod 6. The several scanning rods 6 are connected to the several connecting grooves 5 through inserts 601. The scanning rod 6 is rectangular, and the diameter of the connecting groove 5 is smaller than the diameter of the insert 601, with a tolerance range of 0.05mm-0.1mm. When the insert is inserted into the connecting groove 5, a radial deformation of 0.1mm-0.3mm will occur, forming a self-locking effect. The insertion method of the insert 601 into the connecting groove 5 simplifies the assembly process and improves efficiency. The radial deformation generated when the insert 601 is inserted into the connecting groove 5 ensures the stability of the scanning rod 6 on the jaw support 4 and prevents it from falling off or shifting during operation.

[0046] The face mask 7 has a through hole 701 on its front surface. The through hole 701 is designed to facilitate students' observation of the structure of the jawbone and teeth, and also provides a good visual effect. The front surface of the face mask 7 is an arc-shaped surface. The arc-shaped surface design improves the comfort and user experience of students, and also increases the aesthetics of the model. The face mask 7 is mounted on the surface of the base 1.

[0047] A snap-fit ​​component 8 is provided between the face mask 7 and the base 1. The snap-fit ​​component 8 includes mounting grooves 81 formed on the left and right side walls of the face mask 7. A pair of mounting grooves 81 are respectively provided with connecting plates 82. The connecting plates 82 are elastic elements. The lower ends of the pair of connecting plates 82 are respectively provided with locking blocks 83. The surface of the base 1 is provided with mounting holes 84 for the pair of locking blocks 83 to be inserted into. A limiting seat 85 is provided in the mounting holes 84. The mounting grooves 81, connecting plates 82, locking blocks 83 and mounting holes 84 together constitute a stable connection structure between the face mask 7 and the base 1. The elastic design of the connecting plates 82 allows the locking blocks 83 to be easily inserted into and removed from the mounting holes 84, realizing the quick installation and removal of the face mask 7. The limiting seat 85 ensures the stability of the locking blocks 83 in the mounting holes 84 and prevents them from falling off or shifting.

[0048] Except for the white scanning rod 6, all other components of the aforementioned dental teaching model are pink. The pink design replicates the clinical situation and increases the model's aesthetics and appeal. At the same time, setting the appearance to gray or other colors enhances the overall sense of depth, making the model more three-dimensional and vivid.

[0049] In some embodiments, the insertion post 601 on the scanning rod 6 can be quickly assembled into the connecting groove 5 provided on the jaw seat 4 by magnetic adsorption; by utilizing the principle of magnetic adsorption, the rapid assembly between the scanning rod 6 and the jaw seat 4 is realized, improving assembly efficiency and convenience.

[0050] In some embodiments, the jaw seat 4 can be quickly assembled onto the base 1 and the placement platform 2 by means of magnetic attraction or screw fastening; this provides another option for the rapid assembly of the jaw seat 4, further enhancing the flexibility and practicality of the model.

[0051] In some embodiments, the working principle of the above embodiments is as follows: the face mask 7 can be set in a symmetrical form, and flipping the face mask 7 can quickly simulate the upright and inverted positions of the dental model; by flipping 7, the upright and inverted positions of the dental model can be quickly simulated, which increases the teaching function and fun of the model.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
