Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental prosthesis processing technology, specifically to a dental prosthesis fixing bracket for dental prosthesis processing. Background Technology
[0002] In the field of denture fabrication, denture fixation is a crucial step in ensuring the precision and quality of denture processing. During the fabrication process, dentures need to be stably fixed in a specific position to ensure that subsequent processing operations such as polishing, carving, and coloring can be carried out accurately.
[0003] Currently, due to the wide variety of oral conditions among patients, dentures vary in size and shape, and traditional fixed frameworks often only fit dentures within a specific size range. When faced with dentures of different sizes, different fixed frameworks may need to be replaced, which not only increases the cost of denture processing but also reduces processing efficiency. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a dental prosthesis fixing bracket for dental prosthesis processing, which solves the problem of poor versatility of dental prosthesis fixing brackets in existing technologies.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a denture fixing bracket for denture processing, comprising a base, a hydraulic oil tank fixedly connected to the top of the base, a fixing rod fixedly connected to the outside of the hydraulic oil tank, and an inner support ring fixedly connected to the top of the fixing rod; further comprising: a clamping assembly fixedly connected to the outside of the hydraulic oil tank, the clamping assembly being used to clamp the denture in conjunction with the inner support ring; the clamping assembly comprising an oil reservoir, a flow-blocking component fixedly connected to the outside of the oil reservoir, a piston rod slidably connected to the inside of the oil reservoir, a compression spring fixedly connected to the outside of the piston rod, a movable frame fixedly connected to the end of the piston rod away from the oil reservoir, and an outer clamping plate fixedly connected to the outside of the movable frame by bolts; pulling the movable frame in the clamping assembly outward causes the movable frame to move the outer clamping plate away from the inner support ring, at which point the piston rod moves together with the movable frame, forcing the compression spring to be compressed, thus allowing the denture to be placed between the inner support ring and the clamping assembly.
[0008] Preferably, the clamping assembly is arranged in a fan shape along the outer side of the oil reservoir, and the flow-blocking component is fixedly connected to the outer side of the hydraulic oil tank on the side away from the oil reservoir, so that the hydraulic oil in the hydraulic oil tank can flow into the oil reservoir through the flow-blocking component.
[0009] Preferably, the end of the compression spring away from the piston rod is fixedly connected to the inner wall of the oil reservoir, and the outer side of the movable frame is slidably connected to the outer wall of the oil reservoir. Under the action of the rebound force of the compression spring, the piston rod can drive the outer clamp plate to reset through the movable frame, thereby fixing the denture between the inner support ring and the outer clamp plate.
[0010] Preferably, the flow-blocking component includes a flow-guiding block, a fixed frame is fixedly connected to the top of the flow-guiding block, a threaded rotating rod is rotatably connected to the inner side of the fixed frame, and a flow-blocking plate is threadedly connected to the outer wall of the threaded rotating rod. By rotating the threaded rotating rod, the flow-blocking plate slides downward along the inner side of the fixed frame.
[0011] Preferably, one side of the guide block is fixedly connected to the outer side of the oil reservoir, the other side of the guide block is fixedly connected to the outer wall of the hydraulic oil tank, the bottom of the hydraulic oil tank is fixedly connected to the bottom of the fixing frame, the outer wall of the baffle plate is slidably connected to the inner side of the fixing frame, the bottom of the baffle plate is inserted into the inner wall of the guide block, and the downward sliding baffle plate can be inserted into the guide block, thereby blocking the flow of hydraulic oil in the inner cavity of the guide block and preventing the hydraulic oil in the oil reservoir from flowing back into the hydraulic oil tank.
[0012] (III) Beneficial Effects
[0013] This utility model provides a denture fixing bracket for denture fabrication. It has the following beneficial effects:
[0014] (i) The bracket is equipped with a clamping assembly. The movable frame in the clamping assembly is pulled outward. At this time, the piston rod moves together with the movable frame, which forces the compression spring to be compressed. Then the denture is placed between the inner support ring and the clamping assembly. When the movable frame is released, the piston rod drives the outer clamp plate to reset through the movable frame under the action of the spring force, thereby fixing the denture between the inner support ring and the outer clamp plate. This can accommodate dentures of different sizes and improve the versatility and applicability of the fixed bracket.
[0015] (II) This bracket, by incorporating a flow-blocking component, allows the flow-blocking plate to slide downwards along the inner side of the fixed frame when the threaded rod is rotated. This downward-sliding flow-blocking plate then inserts into the guide block, thereby blocking the flow of hydraulic oil within the guide block's inner cavity and preventing the hydraulic oil in the reservoir from flowing back into the hydraulic tank. In this way, the piston rod will not move due to the flow of hydraulic oil, allowing the outer clamping plate to continuously and stably apply clamping force to the denture, ensuring that the denture does not loosen or shift during processing, and guaranteeing the precision and quality of the denture manufacturing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a denture fixing bracket for denture processing, including a base 1, a hydraulic oil tank 2 fixedly connected to the top of the base 1, a fixing rod 3 fixedly connected to the outside of the hydraulic oil tank 2, an inner support ring 4 fixedly connected to the top of the fixing rod 3, and further including: a clamping assembly 5, which is fixedly connected to the outside of the hydraulic oil tank 2.
[0023] The clamping assembly 5 is used to clamp the denture in conjunction with the inner support ring 4. The clamping assembly 5 includes an oil reservoir 51, a flow-blocking component 52 fixedly connected to the outer side of the oil reservoir 51, a piston rod 53 slidably connected to the inner side of the oil reservoir 51, a compression spring 54 fixedly connected to the outer side of the piston rod 53, and a movable frame 55 fixedly connected to the end of the piston rod 53 away from the oil reservoir 51. An outer clamping plate 56 is fixedly connected to the outer side of the movable frame 55 by bolts. Pulling the movable frame 55 outward in the clamping assembly 5 causes the movable frame 55 to drive the outer clamping plate 56 to move away from the inner support ring 4. At this time, the piston rod 53 moves with the movable frame 55. The frame 55 moves together, forcing the compression spring 54 to be compressed. During this process, the hydraulic oil in the hydraulic oil tank 2 flows into the oil reservoir 51 through the flow-blocking component 52. At the same time, the gap between the outer clamping plate 56 and the inner support ring 4 increases. Then, the denture is placed between the inner support ring 4 and the clamping assembly 5. Then the movable frame 55 is released. At this time, under the action of the rebound force of the compression spring 54, the piston rod 53 drives the outer clamping plate 56 to return to its original position through the movable frame 55, thereby fixing the denture between the inner support ring 4 and the outer clamping plate 56. This can accommodate dentures of different sizes and improve the versatility and applicability of the fixed bracket.
[0024] The clamping assembly 5 is arranged in a fan shape along the outer side of the oil reservoir 51. The side 51 of the flow-blocking component 52 away from the oil reservoir is fixedly connected to the outer side of the hydraulic oil tank 2. The end of the compression spring 54 away from the piston rod 53 is fixedly connected to the inner wall of the oil reservoir 51. The outer side of the movable frame 55 is slidably connected to the outer wall of the oil reservoir 51. Multiple mounting holes are provided on the outer side of the movable frame 55, so that the position of the outer clamp 56 is adjustable. This allows the outer clamp 56 to fit more precisely with the parts of the denture that need to be clamped, thereby optimizing the clamping effect, ensuring that the denture is more stable during processing, and avoiding loosening or displacement of the denture due to improper clamping position, which would affect the processing accuracy and quality of the denture.
[0025] The flow-blocking component 52 includes a flow guide block 521. A fixed frame 522 is fixedly connected to the top of the flow guide block 521. A threaded rotating rod 523 is rotatably connected to the inner side of the fixed frame 522. A flow-blocking plate 524 is threadedly connected to the outer wall of the threaded rotating rod 523. One side of the flow guide block 521 is fixedly connected to the outer side of the oil reservoir 51, and the other side of the flow guide block 521 is fixedly connected to the outer wall of the hydraulic oil tank 2. The bottom of the hydraulic oil tank 2 is fixedly connected to the bottom of the fixed frame 522. The outer wall of the flow-blocking plate 524 is slidably connected to the inner side of the fixed frame 522, and the bottom of the flow-blocking plate 524 is inserted into the inner wall of the flow guide block 521. By rotating the threaded rotating rod 523, the flow-blocking plate 524 slides downward along the inner side of the fixed frame 522. At this time, the downward sliding flow-blocking plate 524 can be inserted into the flow guide block 521, thereby blocking the flow of hydraulic oil in the inner cavity of the flow guide block 521 and preventing the hydraulic oil in the oil reservoir 51 from flowing back into the hydraulic oil tank 2. In this way, the piston rod 53 will not move due to the flow of hydraulic oil, so that the outer clamping plate 56 can continuously and stably apply clamping force to the denture, ensuring that the denture will not loosen or shift during processing, and guaranteeing the accuracy and quality of denture processing.
[0026] In use, the base 1 is placed stably, and the inner support ring 4 is fixed to the hydraulic oil tank 2 by the fixing rod 3. During the denture fixing process, the movable frame 55 in the clamping assembly 5 is first pulled outward, so that the movable frame 55 drives the outer clamping plate 56 to move away from the inner support ring 4. At this time, the piston rod 53 moves with the movable frame 55, forcing the compression spring 54 to be compressed. During this process, the hydraulic oil in the hydraulic oil tank 2 flows into the oil reservoir 51 through the flow blocking component 52. At the same time, the distance between the outer clamping plate 56 and the inner support ring 4 increases. Then the denture is placed between the inner support ring 4 and the clamping assembly 5. Then the movable frame 55 is released. At this time, under the action of the rebound force of the compression spring 54, the piston rod 53 drives the outer clamping plate 56 to return to its original position through the movable frame 55, thereby fixing the denture between the inner support ring 4 and the outer clamping plate 56. This can accommodate dentures of different sizes and improve the versatility and applicability of the fixing bracket.
[0027] The movable frame 55 has multiple mounting holes on its outer side, which makes the position of the outer clamp 56 adjustable. This allows the outer clamp 56 to fit more precisely into the parts of the denture that need to be clamped, thereby optimizing the clamping effect and ensuring that the denture is more stable during processing. This avoids the denture from loosening or shifting due to improper clamping position, which would affect the processing accuracy and quality of the denture.
[0028] Subsequently, by rotating the threaded rod 523, the flow-blocking plate 524 slides downward along the inner side of the fixing frame 522. At this time, the downward sliding flow-blocking plate 524 can be inserted into the guide block 521, thereby blocking the flow of hydraulic oil in the inner cavity of the guide block 521 and preventing the hydraulic oil in the oil reservoir 51 from flowing back into the hydraulic oil tank 2. In this way, the piston rod 53 will not move due to the flow of hydraulic oil, so that the outer clamping plate 56 can continuously and stably apply clamping force to the denture, ensuring that the denture will not loosen or shift during processing, and guaranteeing the accuracy and quality of denture processing.
