Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, and more specifically, to a clamping device for denture production. Background Art

[0002] A clamping device is a device that holds an object to be clamped and then manipulates the object to be clamped. It can avoid direct contact between the hand and the object to be clamped. During the production of dentures, heat treatment is required. When taking out the heat-treated dentures, a clamping device is needed to prevent the hand from being scalded when entering the heat treatment machine.

[0003] When the existing denture clamping device clamps dentures, since the surface of the dentures is irregular and there are many specifications of dentures, the clamping device cannot adapt to various different dentures and the parts in contact with the dentures cannot fit well. Insufficient contact surface will cause the dentures to fall off easily. On the other hand, if the dentures need to be made not to fall off easily, the pressure applied to the dentures needs to be increased. The increased pressure on the dentures will damage the surface of the dentures, thus affecting the quality of denture production. Therefore, a clamping device for denture production is proposed to solve the problem that the clamping device cannot fit the dentures. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a clamping device for denture production. By setting a clamping component, the range of rotation of the inner splint can be increased to better fit the denture, reducing the wear on the denture.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: The clamping device for denture production includes a plurality of outer splints and a plurality of support rods. The outer splints are fixedly connected to the support rods. A clamping component is rotatably connected to each of the plurality of outer splints. A plurality of inner splints are rotatably connected to the side of the clamping component away from the outer splint. A clamping groove is formed on the side of the inner splint away from the clamping component. The inner splints arranged along the length direction of the clamping component are in contact with each other pairwise. When the inner splint abuts against the object to be clamped, the inner splint rotates to drive the clamping component to rotate, increasing the range of the rotation angle of the inner splint so that the inner splint fits the object to be clamped.

[0006] By adopting the above technical solutions, when the inner splint abuts against the denture, the inner splint will rotate on the clamping component along with the denture to fit the denture, making the clamping more stable. The inner splints, which are heart-shaped and in contact with each other pairwise, can increase the contact area with the denture, making the inner splint fit the denture more closely. A closer fit can reduce the probability of the denture falling off and can reduce the degree of damage to the denture caused by increasing the pressure to avoid falling.

[0007] The present utility model is further configured as follows: The clamping assembly includes a plurality of first rotating plates and a plurality of second rotating plates. The plurality of first rotating plates are rotatably connected to the outer clamping plate. The side of the first rotating plate close to the outer clamping plate is arc-shaped. The length of the first rotating plate is half of the length of the outer clamping plate. The plurality of second rotating plates are rotatably connected to the end of the first rotating plate away from the outer clamping plate. The side of the second rotating plate close to the first rotating plate is arc-shaped. The length of the second rotating plate is half of the length of the outer clamping plate.

[0008] By adopting the above technical solution, when the inner clamping plate contacts the object to be clamped, the first rotating plate and the second rotating plate will rotate, thereby expanding the range where the inner clamping plate can move, enabling the inner clamping plate to better fit various specifications of dentures. The side of the first rotating plate close to the outer clamping plate is set to be arc-shaped and the length of the first rotating plate is half of the length of the outer clamping plate, which can make the two first rotating plates symmetrically arranged on the outer clamping plate, and the arc shape can make the first rotating plate rotate flexibly without being blocked by the adjacent first rotating plate. The setting of the second rotating plate has the same effect and further expands the range where the inner clamping plate can rotate on the basis of the first rotating plate.

[0009] The present utility model is further configured as follows: The inner clamping plate is rotatably connected to the side of the second rotating plate away from the first rotating plate. The side of the inner clamping plate close to the second rotating plate is arc-shaped. The length of the inner clamping plate is half of the length of the second rotating plate. The thickness of the inner clamping plate is greater than or equal to the thicknesses of the outer clamping plate, the first rotating plate, and the second rotating plate respectively. The central axes of the inner clamping plate, the outer clamping plate, the first rotating plate, and the second rotating plate in the horizontal direction are on the same horizontal plane.

[0010] By adopting the above technical solution, the arc-shaped inner clamping plate can prevent the adjacent inner clamping plates from being stuck to each other during the rotation process, thereby affecting the rotation and unable to fit well with the dentures. The length of the inner clamping plate being half of the length of the second rotating plate can make the two inner clamping plates symmetrically arranged on the second rotating plate and prevent the inner clamping plates from interfering with each other during rotation. The central axes of the inner clamping plate, the outer clamping plate, the first rotating plate, and the second rotating plate in the thickness direction are on the same horizontal plane and the thickness of the inner clamping plate is the largest. Therefore, when clamping the dentures, it can be ensured that the inner clamping plate can contact the placement table to better clamp the dentures.

[0011] The present utility model is further configured as follows: A first sliding groove is formed on the side of the outer clamping plate close to the inner clamping plate. The first rotating plate is rotatably connected to the inner side wall of the first sliding groove. A second sliding groove is formed on the side of the first rotating plate close to the inner clamping plate. The second rotating plate is rotatably connected to the inner side wall of the second sliding groove. A third sliding groove is formed on the side of the second rotating plate close to the inner clamping plate. The inner clamping plate is rotatably connected to the inner side wall of the third sliding groove. The inner side walls of the first sliding groove, the second sliding groove, and the third sliding groove are all arc-shaped.

[0012] By adopting the above technical solution, the arrangements of the first sliding groove, the second sliding groove and the third sliding groove enable the inner clamping plate, the first rotating plate and the second rotating plate to rotate within a larger range to fit the denture.

[0013] The utility model is further arranged as follows: on one side of the support rod close to the inner clamping plate, a connecting rod is fixedly connected and intermittently abuts against the side wall of the other support rod close to the inner clamping plate. On the side of the other support rod close to the inner clamping plate, a telescopic rod is fixedly connected, and the telescopic rod is slidably connected within the connecting rod.

[0014] By adopting the above technical solution, the connecting rod arranged on the support rod is slidably connected with the telescopic rod to connect the two clamping components. At the same time, the connecting rod and the telescopic rod can enable the two opposite clamping components to move on the same plane to clamp the denture.

[0015] The utility model is further arranged as follows: a connecting groove is formed inside the connecting rod, the telescopic rod is slidably connected to the inner wall of the connecting groove, one end of the telescopic rod far from the connection with the support rod is fixedly connected with an elastic member, and one end of the elastic member far from the telescopic rod is fixedly connected to the inner side wall of the connecting groove.

[0016] By adopting the above technical solution, both the inner wall of the connecting groove and the telescopic rod have edges and corners. The interaction force between the edges and corners of the inner wall of the connecting groove and the telescopic rod can keep the two clamping components on the same horizontal plane. When the telescopic rod slides on the inner wall of the connecting groove, the elastic member is stretched under the action of tension, thus generating a reverse pulling force on the telescopic rod so that the inner clamping plate can still clamp the denture when the external force on the support rod disappears.

[0017] The utility model is further arranged as follows: the hardness of the inner clamping plate is less than the hardness of the object to be clamped.

[0018] By adopting the above technical solution, the hardness of the inner clamping plate being less than the hardness of the clamped denture can prevent the inner clamping plate from wearing the denture during the clamping process, thus affecting the quality of the denture.

[0019] In summary, the utility model has the following beneficial effects: for the clamping device used in denture production, a rotatable clamping component is added to the outer clamping plate. The inner clamping plate rotatably connected to the clamping component can rotate according to the external contour of the clamped denture so as to fit the contour of the denture, achieving the purpose of better clamping the denture. Moreover, the hardness of the inner clamping plate being less than that of the denture can reduce the probability of wearing the denture during the clamping process. And the inner clamping plate is arranged in a heart shape to increase the contact area with the denture, achieving a better fitting effect. The clamping component is provided with a rotatable first rotating plate and a second rotating plate. When the inner clamping plate rotates in contact with the denture, the first rotating plate and the second rotating plate will rotate driven by the inner clamping plate, thereby expanding the rotation angle of the inner clamping plate, enabling the inner clamping plate to fit more angles and thus better fitting different specifications of dentures.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following combines the drawings and embodiments to describe the present utility model in detail.

[0026] The clamping device for denture production, as Figures 1-3 shown, includes two outer clamping plates 1 and two support rods 2. The two outer clamping plates 1 are respectively welded to the two support rods 2. When people clamp the denture, they use their hands to contact the support rods 2 to drive the outer clamping plates 1 to clamp the denture. A clamping assembly is rotatably connected to each of the two outer clamping plates 1. A plurality of inner clamping plates 3 are rotatably connected to the side of the clamping assembly away from the outer clamping plates 1. The inner clamping plates 3 are evenly distributed on the clamping assembly and are in contact with each other in pairs. When the inner clamping plates 3 are in contact with the denture, the inner clamping plates 3 will rotate at different angles on the clamping assembly according to the shape of the outer peripheral wall of the denture to fit the denture, making the clamping state more stable. The inner clamping plates 3 in contact with each other in pairs can reduce the gap with the denture and thus fit more closely. The inner clamping plates 3 are horizontally heart-shaped, and the two arc-shaped sides are used to contact the denture. The heart-shaped inner clamping plates 3 can increase the contact area with the denture, so that the inner clamping plates 3 fit the denture more closely. A closer fit can reduce the probability of the denture falling off and can reduce the pressure applied to avoid falling, thereby causing wear to the denture.

[0027] As Figures 1-3As shown, the clamping assembly includes two first rotating plates 4 and four second rotating plates 5. The first rotating plates 4 are rotatably connected to the outer clamping plate 1, and the second rotating plates 5 are rotatably connected to one end of the first rotating plates 4 away from the outer clamping plate 1. When the inner clamping plate 3 contacts the denture, the interaction force between the inner clamping plate 3 and the denture causes the inner clamping plate 3 to rotate. The rotation of the inner clamping plate 3 drives the second rotating plates 5 and the first rotating plates 4 to rotate as well. The rotation of the first rotating plates 4 and the second rotating plates 5 can expand the range within which the inner clamping plate 3 can move, so that the inner and outer clamping plates 1 can better fit various dentures of different specifications. The side of the first rotating plate 4 close to the outer clamping plate 1 is set to be arc-shaped, which can prevent the first rotating plate 4 from being stuck by the adjacent first rotating plate 4 during rotation. The length of the first rotating plate 4 is half of the length of the outer clamping plate 1 and is symmetrically arranged in the length direction of the outer clamping plate 1. Such a setting of the first rotating plate 4 can make the rotation angles of the two first rotating plates 4 the same, so that the expanded range of the rotation of the inner clamping plate 3 along the central axis in the length direction of the outer clamping plate 1 is also the same. The second rotating plates 5 further expand the rotation range of the inner clamping plate 3 on the basis of the first rotating plates 4.

[0028] As Figures 1-3 shown, the inner clamping plate 3 is rotatably connected to the side of the second rotating plate 5 away from the first rotating plate 4, and the side of the inner clamping plate 3 close to the second rotating plate 5 is arc-shaped. The arc-shaped design can prevent adjacent inner clamping plates 3 from getting stuck with each other during rotation, thus affecting the rotation and preventing the inner clamping plate 3 from fitting well with the denture. The length of the inner clamping plate 3 is half of the length of the second rotating plate 5, which can make the two inner clamping plates 3 symmetrically arranged on the second rotating plate 5 and the adjacent two inner clamping plates 3 will not interfere with each other during rotation. The central axes in the thickness direction of the inner clamping plate 3, the outer clamping plate 1, the first rotating plate 4 and the second rotating plate 5 are on the same horizontal plane, and the thickness of the inner clamping plate 3 is the largest. Therefore, when clamping the denture, it can be ensured that the inner clamping plate 3 can contact the placement table to better clamp the denture.

[0029] As Figures 1-3 shown, a first sliding groove 61 is formed on the side of the outer clamping plate 1 close to the inner clamping plate 3. The first rotating plate 4 is rotatably connected to the inner side wall of the first sliding groove 61. The inner side wall of the first sliding groove 61 is arc-shaped and fits with the outer side wall of the first rotating plate 4. A second sliding groove 62 is formed on the side of the first rotating plate 4 close to the inner clamping plate 3. The second rotating plate 5 is rotatably connected to the inner side wall of the second sliding groove 62. The inner side wall of the second sliding groove 62 is arc-shaped and fits with the outer side wall of the second rotating plate 5. A third sliding groove 63 is formed on the side of the second rotating plate 5 close to the inner clamping plate 3. The inner clamping plate 3 is rotatably connected to the inner side wall of the third sliding groove 63. The inner side wall of the third sliding groove 63 is arc-shaped and fits with the outer side wall of the inner clamping plate 3. The arc-shaped designs of the first sliding groove 61, the second sliding groove 62 and the third sliding groove 63 can allow the first rotating plate 4, the second rotating plate 5 and the inner clamping plate 3 to flexibly rotate at different angles to better fit the denture.

[0030] As Figure 1 , Figure 3 , Figure 4 shown, a connecting rod 7 is welded to the support rod 2. The connecting rod 7 intermittently abuts against the side surface of the adjacent support rod 2. The adjacent support rod 2 is provided with a telescopic rod 8 corresponding to the connecting rod 7. The telescopic rod 8 is slidably connected inside the connecting rod 7. The connecting rod 7 and the telescopic rod 8 connect two clamping assemblies. The connecting rod 7 and the telescopic rod 8 can move the two opposite clamping assemblies on the same plane to clamp the denture and manipulate it.

[0031] As Figure 1 , Figure 3 , Figure 4 shown, the connecting rod 7 is provided with a connecting groove 9. The telescopic rod 8 is slidably connected to the inner wall of the connecting groove 9. Both the inner wall of the connecting groove 9 and the telescopic rod 8 have edges and corners so that a mutual acting force can be generated between the telescopic rod 8 and the inner wall of the connecting groove 9. The mutual acting force between the telescopic rod 8 and the connecting groove 9 keeps the two clamping assemblies on the same horizontal plane. One end of the telescopic rod 8 far from the connection with the support rod 2 is bonded with an elastic member 10. The elastic member 10 is set as a spring. One end of the elastic member 10 far from the telescopic rod 8 is bonded to the inner side wall of the connecting groove 9. When the telescopic rod 8 slides on the inner wall of the connecting groove 9, the elastic member 10 is stretched by the pulling force. Due to the elastic deformation performance of the elastic member 10 itself, a pulling force in the opposite direction will be generated on the telescopic rod 8. When the hand releases the support rod 2, the pulling force of the elastic member 10 on the telescopic rod 8 enables the inner clamping plate 3 to clamp the denture. The material of the inner clamping plate 3 uses graphene, which can prevent the inner clamping plate 3 from wearing the denture when clamping the denture, thus affecting the quality of the denture.

[0032] Working principle: For the clamping device used in denture production, when it is necessary to take out the heat-treated denture from the machine, hold the two support rods 2 with hands respectively and apply an outward pulling force to open the clamping assemblies. Insert the clamping assemblies into the machine and contact the denture. After the inner clamping plate 3 on the clamping assembly contacts the denture, a mutual acting force will be generated with the denture, causing it to rotate to fit the outer peripheral wall of the denture. The rotation of the inner clamping plate 3 will drive the first rotating plate 4 and the second rotating plate 5 to rotate, enabling the range where the inner clamping plate 3 can move to be better, so as to better fit the denture and prevent the denture from falling during the clamping process. After clamping the denture, due to the elastic member 10 between the telescopic rod 8 and the connecting groove 9 generating a pulling force on the two support rods 2, when the force applied to the support rod 2 disappears, the inner clamping plate 3 can still abut against the denture. Then, the denture can be taken out from the heat treatment machine by manipulating the support rod 2. The hardness of the inner clamping plate 3 is less than that of the denture to avoid the inner clamping plate 3 wearing the denture during the clamping process.

[0033] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
