As a non-contact and high-precision measurement technology, three-dimensional scanning technology is widely used in the manufacturing and detection processes of dentures.

[0003] However, in the current working process of placing a denture model on a scanning table for three-dimensional scanning, the denture is often not fixed firmly and shakes, which affects the scanning accuracy and effect, and may fall off, making the denture model easy to be damaged. Therefore, traditional fixing methods, such as using adhesive materials to paste the model on the scanning table, are not only more cumbersome, but also cannot firmly fix the denture model. Therefore, there is an urgent need to develop a jig that can effectively fix the denture model. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a fixing jig that can effectively fix a denture and prevent the denture from shaking and falling off during the scanning operation.

Detailed Embodiments

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the protection scope of the present application.

[0034] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more such features. In the description of the present invention, "a plurality of" means two or more, unless otherwise specifically defined.

[0035] Currently, during the process of placing a denture model on a scanning table for three-dimensional scanning, it often happens that the denture is not fixed firmly and shakes, thus affecting the accuracy and effect of the scanning, and there may also be a situation of dropping, making the denture model prone to damage. Therefore, traditional fixing methods, such as using adhesive materials to paste the model on the scanning table, are not only rather cumbersome but also cannot firmly fix the denture model. Therefore, there is an urgent need to develop a fixture that can effectively fix the denture model to prevent the denture from shaking and dropping during the scanning work, so as to ensure the normal and smooth progress of the denture scanning work.

[0036] Based on this, this embodiment provides a denture fixing fixture 100. Please refer to Figure 1 、 Figures 3 - 5 As shown, it includes a bottom plate 110, a first jaw 111 installed on the bottom plate 110, a second jaw 112, and a housing 113 installed on the bottom plate 110; wherein, the first jaw 111 and the second jaw 112 are oppositely arranged on the bottom plate 110, and there is a fixing position 11a for fixing the denture 200 between the first jaw 111 and the second jaw 112, and the denture is installed in the fixing position 11a; it can be understood that both the first jaw 111 and the second jaw 112 can move closer to or away from the fixing position 11a after being stressed. The first jaw 111 applies a mutual force to the denture 200 by moving to closely adhere to one side of the denture 200, and the second jaw 112 moves towards the denture 200 and closely adheres to the other side of the denture 200. By closely adhering to both sides of the denture 200 with the first jaw 111 and the second jaw 112, the denture 200 is fixed in the fixing position 11a, realizing the clamping of the denture 200.

[0037] Please refer to Figures 1 - 3As shown, according to the above solution, specifically, in this embodiment, the first jaw 111 includes a first jaw bed 121, a first spring 122, and a clamping member 123 fixed to one end of the first jaw bed 121 away from the fixed position 11a. An installation groove 12a is provided in the first jaw bed 121, and the first spring 122 is installed in the installation groove 12a; a retaining piece 131 for blocking the first spring 122 extends from the housing 113 toward the first jaw bed 121, and the retaining piece 131 is aligned with one end of the installation groove 12a close to the clamping member 123; further, the second jaw 112 includes a second jaw bed 141, a second spring 142, a button 143, and a clamping member 123 fixed to one end of the second jaw bed 141 away from the fixed position 11a. The second spring 142 is installed below the button 143; a plurality of limit grooves 13a are provided on one side of the housing 113 facing the second jaw bed 141, and the second spring 142 applies an elastic force to the button 143 to make the button 143 engage with one of the limit grooves 13a.

[0038] According to the above solution, it can be understood that, please refer to Figures 3 - 5As shown, a cavity is formed between the bottom plate 110 and the housing 113. The first clamping bed 121 is installed in the cavity between the bottom plate 110 and the housing 113, and one end of the first clamping bed 121 protrudes outside the housing 113. During the process of clamping the denture 200, after the user places the product on the fixed position 11a, it is necessary to adjust the position of the denture 200 to achieve a firm fixing effect. At this time, the denture 200 will contact the clamping member 123 fixed at the end of the first clamping bed 121, further causing an interaction force between the clamping member 123 and the denture 200. During this process, the first clamping bed 121 may move along with the force exerted by the denture 200 on the clamping member 123. This process causes the first spring 122 located in the installation groove 12a to move towards the direction of the retaining piece 131 as the first clamping bed 121 moves, so that the first spring 122 is blocked by the retaining piece 131 and deformed and compressed, further causing the first spring 122 to generate an elastic force in the direction opposite to the moving direction of the first clamping bed 121, and further causing the clamping member 123 located on the first clamping bed 121 to generate an elastic force on one side of the denture 200, so that the clamping member 123 closely adheres to one side of the denture 200; it can be understood that the second clamping bed 141 is also arranged in the cavity between the bottom plate 110 and the housing 113. The button 143 and the second spring 142 are both installed on the second clamping bed 141, and the second spring 142 is located below the button 143 so that when the button 143 is pressed down by force, an elastic force can be generated between the second spring 142 and the button 143 to make the button 143 reset when not under force. It can be understood that when the button 143 is pressed down so that the button 143 is under force, at this time the button 143 is disengaged from one of the engaging limit grooves 13a on the housing 113, so that the button 143 can move between the housing 113 and the base, making the second clamping bed 141 approach or move away from the denture 200 installed on the fixed position 11a, so as to drive the clamping member 123 located on the second clamping bed 141 to fit with the other side of the denture 200. And when the clamping member 123 on the second clamping bed 141 adheres to the other side of the denture 200, the user can release the button 143, and the button 143 immediately pops up and engages with the aligned limit groove 13a on the housing 113, so that the button 143 is fixed, and further makes the clamping member 123 on the second clamping bed 141 keep closely adhering to the other side of the denture 200, thereby firmly fixing the denture 200 on the fixed position 11a.

[0039] Specifically, please refer to Figure 2 、 Figures 4 - 5As shown in the figure, a limiting post 132 is provided on one side of the housing 113 extending towards the first clamping bed 121. A limiting sliding groove 14a corresponding to the limiting post 132 is provided on the first clamping bed 121. The limiting post 132 penetrates into the limiting sliding groove 14a and can slide back and forth along the groove diameter of the limiting sliding groove 14a, so that the limiting post 132 can limit the moving position of the first clamping bed 121, ensuring that the first spring 122 is in a reasonable deformation range, and preventing the first spring 122 from failing due to excessive deformation or insufficient clamping force during use. Further, a guiding groove 14b is provided on the outer peripheral side of the housing 113. One end of the first clamping bed 121 close to the peripheral side of the bottom plate 110 is embedded in the guiding groove 14b and can move within the guiding groove 14b. The guiding groove 14b limits the two sides of the outer end of the first clamping bed 121, enabling the outer end of the first clamping bed 121 to slide back and forth along the groove diameter of the guiding groove 14b, thereby guiding the movement of the first clamping bed 121 along the moving direction through the guiding groove 14b, making the clamping of the denture 200 on one side by the clamping member 123 on the first clamping bed 121 not deflect and be smoother. In addition, a first guiding opening 13b and a second guiding opening 13c are provided on the housing 113. A slider member 151 is further provided on the second clamping bed 141. The button 143 penetrates into the first guiding opening 13b and can move within the first guiding opening 13b. The slider member 151 penetrates into the second guiding opening 13c and can move within the second guiding opening 13c. This structure is to guide the moving direction of the slider member 151 through the second guiding opening 13c on the housing 113, so that the slider member 151 does not deflect during movement and the clamping is smoother. At the same time, the upper end of the button 143 is limited by the first guiding opening 13b, improving the smoothness effect of the button 143 during the movement after being pressed down.

[0040] As Figure 2 shown, in the above solution, two installation grooves 12a are provided. The two installation grooves 12a are respectively arranged on both sides of the limiting sliding groove 14a. This structure enables the first spring 122 to be also provided with two springs, two compression springs on the left and right, making the formed clamping force more uniform.

[0041] Please refer to Figures 4 - 5 shown, in the above solution, the principle of the movement and fixation of the button 143 is as follows: The limiting groove 13a on the housing 113 is a U-shaped groove. The upper end of the button 143 has a protrusion. When the button 143 is bounced up by the second spring 142, the protrusion and the U-shaped groove form a locking structure, which can fix the position of the slider; when the button 143 is pressed down, the protrusion is disengaged from the U-shaped groove, and the position of the slider member 151 can be quickly moved. In this way, the clamping range can be quickly adjusted to adapt to different sizes of dentures 200, improving the adaptability of the fixture 100.

[0042] Please refer to Figures 1 - 2As shown, preferably, a limiting thread 161 is provided around the outer side of the clamping member 123. Optionally, in this embodiment, the clamping members 123 on the first chuck 121 and the second chuck 141 are both knurled screws, and the limiting thread 161 is a knurled structure. This structure is to enhance the friction between the clamping member 123 and the side of the denture 200, thereby improving the clamping and fixing effect of the clamping member 123 on the denture 200. Further, the knurled screws can also be used in an overlapping manner, that is, an overlapping groove 16a is provided at the end of the clamping member 123, and the clamping member 123 can be inserted into another clamping member 123 through the overlapping groove 16a, so as to clamp and fix the denture 200 model with a higher base. In addition, a rubber band groove 17a is also provided on the bottom plate 110. The rubber band groove 17a can mount a rubber band when clamping an extra-large denture 200 model to better fix the model and further improve the adaptability of the fixture 100.

[0043] Please refer to Figures 2 - 3 As shown, preferably, a receiving groove 17b is further provided on the side of the bottom plate 110 facing the housing 113. The fixing fixture 100 further includes a magnetic attracting sheet 171, and the magnetic attracting sheet 171 is installed in the receiving groove 17b. The magnetic attracting sheet 171 in this embodiment is made of an iron sheet, which facilitates the bottom plate 110 to be adsorbed and fixed by the magnet on the scanning table through the magnetic attracting sheet 171, so as to facilitate the next scanning operation of the denture.

[0044] In summary, the present utility model provides a denture fixing fixture. By placing the denture on the fixing position spaced between the first jaw and the second jaw, and applying a mutual acting force to the denture by the first jaw to closely adhere to one side of the denture, and the second jaw moves towards the denture and closely adheres to the other side of the denture, the denture is fixed, avoiding the influence of the denture shaking due to unstable fixation on the scanning accuracy and effect, and also preventing the denture from falling during the scanning process, ensuring the normal and smooth progress of the denture scanning work.
