Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis models, specifically a dental prosthesis printing model fixing base. Background Technology

[0002] Dentures are what people commonly refer to as "false teeth." Just as "prosthetic legs" or "prosthetic limbs" are called "prosthetics," "dentures" refer to teeth that fulfill their "duties" for humans. Traditionally, making teeth requires first using a mold and then grinding it according to the mold, which is quite cumbersome. With the continuous maturation of 3D printing technology, 3D printing technology has begun to be used to make dentures. When printing dentures, clamps (i.e., fixing bases) are needed to hold the dentures in place to prevent them from moving during printing.

[0003] According to Chinese Patent No. CN215688626U, a 3D printing fixture for dentures is disclosed. This utility model prints dentures in the center of a turntable. A rotating adjustment rod drives an adjustment bar to move. The adjustment bar drives a gear and a turntable to rotate through gear teeth. At this time, the drive shaft moves in a guide groove. The guide groove drives the adjustment plate and the clamping plate to move, clamping the denture. It can adapt to dentures of different sizes. When clamping dentures of different shapes, the clamping plate can be replaced. During clamping, the spring can buffer to avoid excessive clamping force causing denture deformation. The fixture can clamp dentures of different sizes and shapes, has strong practicality, and is easy to promote.

[0004] Regarding the aforementioned patent content, four clamping plates are used to clamp and limit the denture. However, the shape of the denture is irregular. When the four clamping plates move simultaneously, due to the different distances between the four clamping plates and the denture, some clamping plates will contact the denture first, while others will contact it later. The clamping plate that contacts the denture first will compress the corresponding spring, causing the spring to be compressed. At the same time, the clamping plate will be subjected to the spring's reaction force. As the clamping plates that have not yet contacted the denture continue to move, the clamping plates that have contacted the denture first will experience a greater reaction force from the spring, which will exert a greater compressive force on the denture contact surface, potentially damaging the denture and reducing the clamping effect. A T-shaped retaining groove is provided to replace the clamping plates, but the clamping plates are not limited after being inserted into the T-shaped retaining groove, resulting in poor stability of the clamping plates, which may cause wobbling and thus affect the clamping effect of the denture. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a denture printing model fixing seat to solve the technical problem that the existing clamping method may damage the denture model due to excessive clamping force.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dental prosthesis printing model fixing base, comprising a base plate, a fixing block mounted on the top of the base plate, and a first positioning block mounted on the fixing block by a first bolt; a sliding groove is also provided on the top of the base plate, and a threaded column is connected to the inside of the sliding groove by a bearing; a threaded seat is fitted on the outer wall of the threaded column, and an adjusting seat is mounted on the top of the threaded seat; frames are fixed on both sides of the adjusting seat, and a movable shaft is connected to the inside of the frames by a bearing; a worm gear and a rotating plate are respectively mounted on the outer wall of the movable shaft; a clamping plate is mounted on the rotating plate by a second bolt; a worm is also connected to the inside of the frames by a bearing; and a second positioning block is mounted on the back of the adjusting seat by a first bolt.

[0007] By adopting the above technical solution, when the threaded column is rotated, the threaded column can drive the threaded seat to move, which in turn drives the adjusting seat to move.

[0008] Furthermore, a protective pad is installed on one side of the clamp, and the protective pad is made of rubber material.

[0009] By adopting the above technical solution, the protective pad can play a protective role, preventing the splint from directly contacting the denture model.

[0010] Furthermore, the bottom of the adjustment seat is fitted to the top of the base plate.

[0011] By adopting the above technical solution, the adjustment seat can be moved smoothly.

[0012] Furthermore, one end of the threaded column extends to the outside of the base plate and is equipped with a knob, and both sides of the threaded seat are in contact with the inner wall of the slide groove.

[0013] By adopting the above technical solution, it is convenient for staff to rotate the threaded column by turning the knob, and the rotation of the threaded column will drive the threaded seat to move.

[0014] Furthermore, both the clamping plate and the protective pad are arc-shaped, and the clamping plate and the protective pad are detachably connected to the rotating plate.

[0015] The above technical solution allows for the replacement of the clamps and protective pads.

[0016] Furthermore, both the top of the fixing block and the top of the adjusting seat are provided with snap-fit ​​grooves, the first positioning block is detachably connected to the fixing block, and the second positioning block is detachably connected to the adjusting seat.

[0017] By adopting the above technical solution, the first positioning block or the second positioning block can be disassembled and replaced.

[0018] Furthermore, one end of the worm gear extends to the outside of the frame and is fitted with a handle.

[0019] By adopting the above technical solution, it is convenient for workers to rotate the worm gear using the handle.

[0020] Furthermore, the worm gear meshes with a worm wheel, which is located above the rotating plate.

[0021] By adopting the above technical solution, the rotation of the worm gear can drive the rotation of the worm wheel, and the rotation of the worm wheel will drive the rotation of the movable shaft.

[0022] Furthermore, the clamping plate and the rotating plate are rotatably connected to the frame via a movable shaft.

[0023] By adopting the above technical solution, the rotation of the movable shaft will drive the rotating plate to rotate, which in turn drives the clamping plate to rotate, so as to adjust the angle of the clamping plate.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by comprising a worm gear, a worm shaft, a movable shaft, a rotating plate, a clamping plate, and a protective pad, allows for the clamping of a denture model. First, the first and second positioning blocks contact the denture model. Then, the worm shaft is rotated sequentially. The rotation of the worm shaft drives the worm wheel shaft, which in turn drives the movable shaft, rotating the rotating plate and clamping plate. Once the protective pad is tightly fitted to the denture model, the worm shaft is no longer rotated. This clamping and limiting mechanism prevents the denture model from moving freely. This method improves the clamping effect and avoids damage to the denture model caused by the simultaneous movement of all four clamping structures. Simultaneously, the protective pad prevents the clamping plate from directly contacting the denture model and prevents excessive pressure from the clamping plate, which could damage the denture model.

[0026] 2. Because the worm and worm wheel have self-locking properties, they can prevent the clamping plate from rotating randomly, thereby improving the stability of the clamping plate and enabling the clamping plate and protective pad to stably hold the denture model. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1:

[0037] A denture printing model holder, such as Figures 1-6 As shown, the device includes a base plate 1, a fixing block 2 is installed on the top of the base plate 1, and a first positioning block 4 is installed on the fixing block 2 by a first bolt 6. A sliding groove 8 is also provided on the top of the base plate 1, and a threaded column 7 is connected to the inside of the sliding groove 8 through a bearing. A threaded seat 9 is fitted on the outer wall of the threaded column 7, and an adjusting seat 10 is installed on the top of the threaded seat 9. Frames 11 are fixed on both sides of the adjusting seat 10, and a movable shaft 13 is connected to the inside of the frame 11 through a bearing. A worm gear 14 and a rotating plate 15 are respectively installed on the outer wall of the movable shaft 13.

[0038] See Figures 1-5 A clamping plate 16 is installed on the rotating plate 15 by a second bolt 17. A worm gear 12 is also connected to the inside of the frame 11 by a bearing. A second positioning block 5 is installed on the back of the adjusting seat 10 by a first bolt 6. When the threaded column 7 is rotated, the threaded column 7 can drive the threaded seat 9 to move, which in turn drives the adjusting seat 10 to move. The bottom of the adjusting seat 10 is in contact with the top of the base plate 1 so that the adjusting seat 10 can move smoothly. One end of the threaded column 7 extends through to the outside of the base plate 1 and is equipped with a knob. Both sides of the threaded seat 9 are in contact with the inner wall of the slide groove 8, which makes it convenient for the operator to rotate the threaded column 7 by the knob. After the threaded column 7 is rotated, it will drive the threaded seat 9 to move.

[0039] Specifically, both the top of the fixing block 2 and the top of the adjusting seat 10 are provided with snap-fit ​​grooves. The first positioning block 4 is detachably connected to the fixing block 2, and the second positioning block 5 is detachably connected to the adjusting seat 10, so that the first positioning block 4 or the second positioning block 5 can be disassembled and replaced. One end of the worm 12 extends to the outside of the frame 11 and is equipped with a handle, which allows the operator to rotate the worm 12 by rotating the handle. The worm 12 meshes with the worm wheel 14, which is located above the rotating plate 15. After the worm 12 rotates, it can drive the worm wheel 14 to rotate. The rotation of the worm wheel 14 will drive the movable shaft 13 to rotate. The clamping plate 16 and the rotating plate 15 are rotatably connected to the frame 11 through the movable shaft 13. After the movable shaft 13 rotates, it will drive the rotating plate 15 to rotate, and then drive the clamping plate 16 to rotate, so as to adjust the angle of the clamping plate 16. A silicone pad is installed on the side of the second positioning block 5 away from the adjusting seat 10.

[0040] Example 2:

[0041] Based on the above embodiment 1, in order to prevent the splint 16 from directly contacting the denture model, the following structure will be set.

[0042] See Figures 1-5 A protective pad 3 is installed on one side of the clamp 16. The protective pad 3 is made of rubber material. The protective pad 3 can play a protective role and prevent the clamp 16 from directly contacting the denture model. Both the clamp 16 and the protective pad 3 are arc-shaped. The clamp 16 and the protective pad 3 are detachable from the rotating plate 15 so that the clamp 16 and the protective pad 3 can be removed and replaced.

[0043] The working principle of this utility model is as follows: First, when in use, the operator places the denture model on the base plate 1 and makes the back of the denture model contact the first positioning block 4. Then, the operator rotates the threaded column 7. The rotation of the threaded column 7 drives the threaded seat 9 to move, and drives the adjusting seat 10 to move. The adjusting seat 10 drives the second positioning block 5 to move. After the silicone pad on the second positioning block 5 is tightly attached to the denture model, the threaded column 7 is no longer rotated. Then, the operator rotates the two worm gears 12 in sequence. The rotation of the worm gears 12 drives the worm wheel 14 to rotate. The worm wheel 14 drives the movable shaft 13 to rotate, and drives the rotating plate 15 and the clamping plate 16 to rotate. When the protective pad 3 is tightly attached to the denture model, the worm gears 12 are no longer rotated. In this way, the denture model can be clamped and limited to prevent it from moving at will.

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
