Description

Personalized crown rapid positioning device Technical Field

[0001] This utility model relates to the field of dental crown mold positioning technology, and in particular to a personalized dental crown rapid positioning device. Background Technology

[0002] The crown mold rapid positioning device is an auxiliary tool used in dental restoration to improve fabrication efficiency. It is mainly used to accurately position the mold when making a crown (or bridge). The mold is fixed by mechanical or magnetic structure to avoid repeated calibration, improve fabrication consistency, and ensure the fit between the restoration and the patient's teeth.

[0003] Existing personalized crown rapid positioning devices lack an automatic flipping and positioning structure for the upper crown. This design deficiency makes it difficult to adjust and accurately position the upper crown at multiple angles during the examination process. It also makes it impossible to directly observe the matching of the upper and lower crowns at different occlusal angles, which seriously affects the accuracy of the restoration and clinical efficiency, increasing both workload and reducing restoration precision.

[0004] Therefore, to address the problem that existing crown positioning devices lack an automatic crown flipping function and make it difficult to observe the matching of upper and lower crowns from multiple angles, a personalized crown rapid positioning device can be designed. Summary of the Invention

[0005] To overcome the problem that existing crown positioning devices lack the function of automatically flipping the upper crown, making it difficult to observe the matching of the upper and lower crowns from multiple angles.

[0006] The technical solution of this utility model is as follows: a personalized crown rapid positioning device, comprising a base, curved arms, and a rotating shaft. Columns are installed at both ends of the base, and support rods are provided at the top of each column. A transmission shaft is rotatably connected between the two support rods. First transmission discs are provided at both ends of the transmission shaft. Curved arms are provided at both ends of the rear side of the base, and a rotating shaft is rotatably connected between the two curved arms. Two symmetrical second transmission discs are fitted around the rotating shaft, and a belt is fitted between the corresponding first and second transmission discs. A drive motor is embedded in the top center of the base, and a first bevel gear is connected to the output end of the drive motor. The drive motor drives the first bevel gear to rotate. Second bevel gears are fitted around the rotating shaft at positions corresponding to the first bevel gears, and the first and second bevel gears mesh with each other. A battery compartment is installed at the bottom of the base, and a battery for powering the drive motor is placed inside the battery compartment. A sleeve is installed around the transmission shaft between the two first transmission discs. Positioning components for positioning the crown are provided on the front side of the base and the rear side of the sleeve.

[0007] Preferably, by setting up a drive motor, the battery provides power for the operation of the drive motor. When the drive motor is in operation, the output end drives the first bevel gear to rotate. Through the meshing transmission of the second bevel gear, the shaft rotates. When the shaft rotates, it can drive the two second transmission discs to rotate synchronously. Through belt linkage, the two first transmission discs drive the transmission shaft to rotate, thereby driving the upper positioning component to perform multi-angle rotational positioning adjustment. This drives the upper crown to flip and stop at different angles to observe the matching degree with the lower crown. This solves the problem that the existing personalized crown rapid positioning device does not have an automatic flipping and positioning structure for the upper crown, and it is not convenient to observe the matching of the upper and lower crowns at multiple angles.

[0008] Preferably, the positioning component includes a base plate, a positioning groove, a first magnet, and a placement seat; the front side of the base and the rear side of the sleeve are both connected to the base plate, the top of the two base plates are provided with positioning grooves, the bottom of the positioning grooves are provided with the first magnets, and the top of the base plates are connected to the placement seat through the positioning grooves. By providing positioning grooves, the placement seat can be positioned, and the first magnets can attract each other with the magnetic blocks at the bottom of the placement seat, thereby realizing the assembly of the placement seat.

[0009] Preferably, the positioning component also includes a slot and a second magnet; the top of the placement seat has a slot, and the center of the top of the placement seat is equipped with a second magnet for adsorbing the crown. By setting the slot and the second magnet, the crown can be positioned and installed, improving the ease of installation.

[0010] Preferably, the drive shaft has external threads on both the left and right ends, and positioning caps are connected to the left and right ends of the drive shaft through the external threads. The positioning caps have anti-slip textures on both the front and back sides. By setting the external threads, the positioning caps can be connected to the drive shaft, thereby restricting the drive shaft between the two columns and preventing the drive shaft from shifting position.

[0011] Preferably, heat dissipation slots are provided at both the left and right ends of the battery compartment, and cooling fans are installed inside the battery compartment at the corresponding positions of the heat dissipation slots. By setting up heat dissipation slots, the cooling fans inside the battery compartment can drive air circulation through the heat dissipation slots during operation, thereby avoiding the problem of battery overheating and explosion.

[0012] Preferably, anti-slip pads are installed on the bottom of both columns and the front base plate. The cooling fan is electrically connected to the battery in the battery compartment. By setting the pads, the overall anti-slip performance of the device can be improved, and the stability during use can be enhanced.

[0013] Preferably, a fixing plate is provided at the front end of the rear base plate, and fixing screws are provided at the four rear corners of the fixing plate. The fixing plate is fixed to the sleeve by fixing screws. By setting fixing screws, the positioning plate can be fixed, thereby improving the stability of the rear base plate.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a flip-up positioning component, the crown model can be rotated freely and precisely positioned in all directions. Staff can observe the occlusal contact of the upper and lower crowns from any angle, significantly improving the accuracy and comprehensiveness of occlusal relationship assessment. This dynamic visualization design not only supports multi-angle matching detection, but also simulates the occlusal state under different jaw positions in real time, providing a reliable basis for the precise adjustment of restorations. Compared with the traditional fixed observation method, this device greatly improves the work efficiency of dental restoration, makes the mold calibration process more flexible and controllable, and ultimately ensures that the restoration achieves ideal occlusal function and aesthetic effect.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to Figures 1-5. This utility model provides an embodiment of a personalized crown rapid positioning device, including a base 1, a curved arm 6, and a rotating shaft 22. Columns 2 are installed at both ends of the base 1, and support rods 3 are provided at the top of each column 2. A transmission shaft 4 is rotatably connected between the two support rods 3. First transmission discs 5 are provided at both ends of the transmission shaft 4. Curved arms 6 are provided at both ends of the rear side of the base 1, and a rotating shaft 22 is rotatably connected between the two curved arms 6. Two symmetrical second transmission discs 7 are sleeved around the rotating shaft 22. A belt 8 is sleeved between the corresponding first transmission discs 5 and second transmission discs 7. A drive motor 9 is embedded in the top center of the base 1. The output end of the drive motor 9 is connected to a first bevel gear 10, which drives the first bevel gear 10 to rotate. Second bevel gears 11 are sleeved around the rotating shaft 22 at positions corresponding to the first bevel gear 10. The first bevel gear 10 meshes with the second bevel gear 11. A battery compartment 12 is installed at the bottom of the base 1, and a battery for powering the drive motor 9 is placed inside the battery compartment 12. A sleeve 13 is installed around the drive shaft 4 between the two first drive discs 5. Positioning components for positioning the crown are provided on the front side of the base 1 and the rear side of the sleeve 13. Power is provided by the drive motor 9, and the battery supplies power to the drive motor 9. When working, the output end of the drive motor 9 drives the first bevel gear 10 to rotate. Through meshing with the second bevel gear 11, it drives the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, it synchronously drives the two second drive discs 7 to rotate. Then, through the belt 8, the two first drive discs 5 drive the drive shaft 4 to rotate, thereby driving the positioning components above to achieve multi-angle rotation positioning. Through this kinematic chain, the upper crown can be flipped and kept stably at different angles to observe the matching with the lower crown.

[0024] Please refer to Figures 2-4. In this embodiment, the positioning assembly includes a base plate 141, a positioning groove 142, a first magnet 143, and a placement seat 144. The front side of the base 1 and the rear side of the sleeve 13 are both connected to the base plate 141. The top of each base plate 141 has a positioning groove 142, and the bottom of the positioning groove 142 is provided with the first magnet 143. The top of the base plate 141 is connected to the placement seat 144 through the positioning groove 142. By providing the positioning groove 142, the placement seat 144 can be positioned. The first magnet 143 can attract the magnetic block at the bottom of the placement seat 144, thereby assembling the placement seat 144. The positioning assembly also includes a slot 145 and... The second magnet 146; the top of the placement seat 144 is provided with a slot 145, and the center of the top of the placement seat 144 is provided with a second magnet 146 for adsorbing the crown. By setting the slot 145 and the second magnet 146, the crown can be positioned and installed, which improves the ease of installation. The left and right ends of the drive shaft 4 are provided with external threads 15. The left and right ends of the drive shaft 4 are connected to positioning caps 16 through the external threads 15. The front and back sides of the positioning caps 16 are machined with anti-slip textures 17. By setting the external threads 15, the positioning caps 16 can be connected to the drive shaft 4, thereby restricting the drive shaft 4 between the two columns 2 and preventing the position of the drive shaft 4 from shifting.

[0025] Please refer to Figures 1-5. In this embodiment, heat dissipation slots 18 are provided at both the left and right ends of the battery compartment 12. Cooling fans are installed inside the battery compartment 12 at positions corresponding to the heat dissipation slots 18. By setting the heat dissipation slots 18, the cooling fans inside the battery compartment 12 can drive air circulation through the heat dissipation slots 18 during operation, thereby avoiding the problem of battery overheating and explosion. Anti-slip pads 19 are installed at the bottom of the two columns 2 and the front base plate 141. The cooling fans are electrically connected to the battery inside the battery compartment 12. By setting the pads 19, the overall bottom anti-slip performance of the device can be improved, and the stability during use can be improved. A fixing plate 20 is provided at the front end of the rear base plate 141. Fixing screws 21 are provided at the four rear corners of the fixing plate 20. The fixing plate 20 is fixed to the sleeve 13 by fixing screws 21. By setting the fixing screws 21, the positioning plate can be fixed, improving the stability of the rear base plate 141.

[0026] During installation, the drive shaft 4 passes through the two support rods 3, and the two ends are fixed in place with positioning caps 16. The placement seat 144 is fixed to the surface of the base plate 141 by means of the first magnet 143. The lower crown and the upper crown are respectively attracted to the corresponding placement seat 144 by the second magnet 146. When the battery supplies power to the drive motor 9, the motor output drives the first bevel gear 10 to rotate. After being meshed and transmitted by the second bevel gear 11, it drives the rotating shaft 22 to rotate. The rotating shaft 22 synchronously drives the two second transmission discs 7 to rotate. Through the belt 8, the two first transmission discs 5 drive the drive shaft 4 to rotate, thereby realizing the upper base plate 141 to drive the upper crown to perform multi-angle rotation positioning adjustment.

[0027] Through the above steps, by setting up a drive motor 9, after the drive motor 9 is started, its output shaft drives the first bevel gear 10 to rotate. The second bevel gear 11 meshing with it transmits power to the rotating shaft 22. The second transmission discs 7, which are symmetrically installed at both ends of the rotating shaft 22, transmit the rotational motion synchronously to the corresponding first transmission disc 5 through the belt 8, thereby driving the transmission shaft 4 to rotate. The upper end of the transmission shaft 4 is connected to the positioning component. Through the coordinated action of this series of transmission mechanisms, the positioning component can achieve multi-angle precision rotation. During this process, the upper crown completes the flipping action with the positioning component and can be precisely positioned at any angle, which makes it convenient for the operator to observe and evaluate its occlusal matching degree with the lower crown from different positions. This solves the problem that the existing personalized crown rapid positioning device does not have an automatic flipping and positioning structure for the upper crown when in use, and it is not convenient to observe the matching of the upper crown and the lower crown at multiple angles.
