Description
Technical Field
[0001] This utility model relates to the field of denture base technology, and in particular to a denture base that is easy to assemble and disassemble. Background Technology
[0002] The denture base is the physical connection carrier for components such as artificial teeth, retention devices, and connectors. By shaping the model material, the base fixes these disparate components into a whole, simulating the final assembly relationship of the denture in the oral cavity, making it easier for technicians to check the coordination of each component.
[0003] Currently, the denture mounting block and the denture base body are usually fixedly connected. Through the overall shaping or rigid bonding of the model material, the denture mounting block and the denture base body can be firmly fixed into a whole. This avoids positional displacement caused by loose connection during the occlusion test and component coordination verification of the model, ensuring that the simulated assembly relationship is closer to the design expectation and reducing errors caused by component shaking.
[0004] While fixed-connection denture bases offer strong structural stability, they also present significant challenges in modification. Modification often requires grinding or cutting the entire base to adjust the mounting blocks, which can damage the overall structure and even necessitates rebuilding the entire model, increasing time and material costs. Furthermore, when different mounting block models are needed to test different artificial tooth morphologies or adjust retention device specifications, fixed-connection denture bases cannot be disassembled individually, necessitating the destruction of the original connection structure. This results in low model reusability and difficulty in quickly adapting to individual needs. Therefore, a denture base that facilitates easy assembly and disassembly is proposed to address these issues. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a denture base that facilitates denture assembly and disassembly, aiming to improve the problem in the prior art that the denture mounting blocks on the denture base cannot be disassembled individually.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A denture base that facilitates denture assembly and disassembly includes a slot block, an arc-shaped block slidably connected to the inner side of the slot block, a plurality of mounting block snap-fit components disposed on the inner side of the arc-shaped block, an arc-shaped shell fixedly connected to both ends of the arc-shaped block, a plurality of snap-fit fixing components disposed on the inner side of the arc-shaped shell, and a housing fixedly connected to the inner side of both ends of the slot block, with an assembly and disassembly component disposed on the inner side of both housings. The mounting block snap-fit assembly includes a fixing rod, which is rotatably connected to the inner side of the arc-shaped block. Two sliders are fixedly connected to the outer side of the fixing rod, and both sliders are rotatably connected to the inner side of the arc-shaped block. A denture mounting block is fixedly connected to the top of the fixing rod, and a slot is provided on the inner side of the fixing rod. As a further description of the above technical solution: The snap-fit fixing assembly includes a snap-fit rod two, which is slidably connected to the inner side of the arc-shaped shell. A spring three is sleeved on the outer side of the snap-fit rod two, and the end of the snap-fit rod two is slidably connected to the inner side of the snap-fit groove. As a further description of the above technical solution: The installation and disassembly assembly includes a snap-fit rod 1, which is slidably connected to the inner side of the housing. An L-shaped rod is slidably connected to the end of the snap-fit rod 1 away from the snap-fit rod 1. The L-shaped rod is also slidably connected to the inner side of the housing. Two spring push rods are fixedly connected to the bottom of the housing. Spring 1 and Spring 2 are respectively sleeved on the outer side of the two spring push rods. The snap-fit rod 1 is fixedly connected to one end of one of the spring push rods. Spring 2 is located at the bottom of the snap-fit rod 1. The L-shaped rod is fixedly connected to the end of the other spring push rod. Spring 1 is located at the bottom of the L-shaped rod. As a further description of the above technical solution: The installation and disassembly assembly also includes a rotating locking block, which is rotatably connected to the inner side of the L-shaped rod, and the middle part of the rotating locking block is rotatably connected to the inner side of the housing. The end of the rotating locking block away from the L-shaped rod is locked to the inner side of the locking rod. As a further description of the above technical solution: Multiple limiting blocks are fixedly connected to the side of the arc-shaped block, and the multiple limiting blocks are slidably connected to the inner side of the slot block. As a further description of the above technical solution: One end of each of the two snap-fit rods is fixedly connected to both ends of the arc-shaped block, and a pressing rod is fixedly connected to the top of each of the two L-shaped rods. The pressing rod is slidably connected to the inner side of the housing. As a further description of the above technical solution: Each of the aforementioned locking rods has a pull ring fixedly connected to both ends; As a further description of the above technical solution: The bottom of the card slot block is fixedly connected to a base.
[0007] This utility model has the following beneficial effects: 1. In this utility model, the fixed rod drives the slider to rotate inside the arc-shaped block. At the same time, the pull ring drives the second locking rod to slide and compress the third spring. After the spring is released, the third spring drives the second locking rod to insert into the slot, thereby achieving a stable lock of the denture mounting block. It can adapt to personalized oral needs. The denture mounting block can be disassembled and replaced separately. When the denture is partially worn or damaged, it is not necessary to replace the entire base, but only the denture mounting block needs to be replaced, thus reducing maintenance costs.
[0008] 2. In this utility model, the arc-shaped block drives the limiting block to slide inside the slot block. Simultaneously, the arc-shaped block pushes the locking rod one, causing the rotating block to rotate and pushing the L-shaped rod. Combined with the elastic action of spring one and spring two, this achieves precise alignment and secure self-locking between the arc-shaped block and the slot block, improving installation efficiency and stability. By pressing the rod to drive the L-shaped rod to slide, the rotating block rotates in the opposite direction. The return of spring two causes the locking rod one to reset, thus achieving quick unlocking of the arc-shaped block and the slot block, facilitating effortless disassembly.

Detailed Implementation
[0011] 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.
[0012] Reference Figure 1 , Figure 5 , Figure 7 and Figure 8 An embodiment of this utility model provides a denture base that is easy to assemble and disassemble, including a slot block 2, an arc-shaped block 5 slidably connected to the inner side of the slot block 2, a plurality of mounting block snap-fit components provided on the inner side of the arc-shaped block 5, an arc-shaped shell 3 fixedly connected to both ends of the arc-shaped block 5, a plurality of snap-fit fixing components provided on the inner side of the arc-shaped shell 3, and a housing 10 fixedly connected to the inner side of both ends of the slot block 2, and an assembly and disassembly component provided on the inner side of both housings 10; The mounting block assembly includes a fixing rod 20, which is rotatably connected to the inner side of the arc-shaped block 5. Two sliders 13 are fixedly connected to the outer side of the fixing rod 20, and both sliders 13 are rotatably connected to the inner side of the arc-shaped block 5. A denture mounting block 4 is fixedly connected to the top of the fixing rod 20, and a slot 12 is provided on the inner side of the fixing rod 20. The denture mounting block 4 is rotatably connected to the arc-shaped block 5 through the fixing rod 20, and the sliders 13 on the outer side of the fixing rod 20 rotate inside the arc-shaped block 5. The denture mounting block 4 is securely mounted inside the arc-shaped block 5 through the fixing rod 20 and the outer sliders 13.
[0013] Reference Figure 2 , Figure 3 and Figure 5 The snap-fit fixing assembly includes a snap-fit rod 21, which is slidably connected to the inner side of the arc-shaped shell 3. A spring 3 19 is sleeved on the outer side of the snap-fit rod 21, and the end of the snap-fit rod 21 is slidably connected to the inner side of the slot 12. Pull rings 9 are fixedly connected to the ends of multiple snap-fit rods 21. Pulling the pull ring 9 on the outer side of the arc-shaped shell 3 causes the snap-fit rod 21 to slide outward from the arc-shaped shell 3 and compress the spring 3 19. Aligning the slot 12 on the inner side of the fixing rod 20 with the end of the snap-fit rod 21, releasing the pull ring 9 causes the spring 3 19 to rebound and push the snap-fit rod 21 into the slot 12, locking the angle of the defining tooth mounting block 4.
[0014] Reference Figure 1 , Figure 4 and Figure 6The installation and disassembly assembly includes a snap-fit rod 7, which is slidably connected to the inside of the housing 10. An L-shaped rod 14 is slidably connected to the end of the snap-fit rod 7 away from its end, and is also slidably connected to the inside of the housing 10. Two spring push rods 18 are fixedly connected to the bottom of the housing 10. A spring 16 and a spring 2 17 are respectively fitted onto the outer sides of the two spring push rods 18. The snap-fit rod 7 is fixedly connected to one end of one of the spring push rods 18, and the spring 2 17 is located at the bottom of the snap-fit rod 7. The L-shaped rod 14 is fixedly connected to the end of the other spring push rod 18, and the spring 16 is located at the bottom of the L-shaped rod 14. The arc-shaped block 5 pushes the snap-fit rods 7 at both ends to slide inwards towards the inside of the housing 10. The snap-fit rod 7 compresses the spring 2 17 at the bottom, pressing down on the pressing rod 6, which drives the rotating block 15 to rotate clockwise around the fulcrum inside the housing 10, simultaneously compressing the spring 16. After the arc-shaped block 5 is fully inserted, releasing the pressing rod 6 causes one end of the rotating locking block 15 to engage with the inner groove of the locking rod 7 under the push of the spring 16, forming a self-locking mechanism that firmly fixes the arc-shaped block 5 to the locking block 2. The installation and disassembly assembly also includes the rotating locking block 15, which is rotatably connected to the inner side of the L-shaped rod 14. The middle part of the rotating locking block 15 is rotatably connected to the inner side of the housing 10, and the end of the rotating locking block 15 away from the L-shaped rod 14 is engaged with the inner side of the locking rod 7. The ends of the two locking rods 7 are respectively fixedly connected to the two ends of the arc-shaped block 5, and the tops of the two L-shaped rods 14 are fixedly connected with the pressing rod 6, which is slidably connected to the inner side of the housing 10. Pressing the pressing rod 6 on the outside of the housing 10 causes the L-shaped rod 14 to slide towards the bottom of the housing 10. The L-shaped rod 14 pushes the rotating block 15 to rotate clockwise, causing its protrusion to disengage from the groove of the first locking rod 7. The second spring 17 rebounds and pushes the first locking rod 7 back to its original position, releasing the lock on the arc-shaped block 5. The arc-shaped block 5 can then be pulled out along the slide groove. Pulling the pull ring 9 outwards causes the second locking rod 11 to disengage from the slot 12, releasing the lock on the fixing rod 20. The denture mounting block 4, along with the fixing rod 20, can then be removed from the arc-shaped block 5.
[0015] Reference Figure 1 and Figure 4 Multiple limiting blocks 8 are fixedly connected to the side of the arc-shaped block 5, and these limiting blocks 8 are slidably connected to the inner side of the slot block 2. The limiting blocks 8 move synchronously within the slide groove along with the arc-shaped block 5. Because the shape of the limiting blocks 8 matches that of the slide groove, the lateral displacement of the arc-shaped block 5 perpendicular to the sliding direction can be limited, ensuring that the arc-shaped block 5 always slides precisely along the preset path, avoiding installation jamming or disassembly obstruction caused by displacement. A base plate 1 is fixedly connected to the bottom of the slot block 2. The base plate 1 provides stable foundation support for the entire denture base.
[0016] Working principle: First, the arc-shaped block 5 is slidably inserted into the groove on the inner side of the slot block 2, and the limiting block 8 slides in the slot block 2 to ensure accurate installation direction and prevent lateral displacement.
[0017] When the arc-shaped block 5 is inserted into the slot block 2, it pushes the locking rod 7 to slide inward into the housing 10, compressing the spring 17. Pressing the L-shaped rod 14 causes the other end of the rotating block 15 to push the L-shaped rod 14 downward, compressing the spring 16, and simultaneously causing the rotating block 15 to rotate. When the arc-shaped block 5 is fully inserted, one end of the rotating block 15 engages with the groove of the locking rod 7, forming a mechanical lock and fixing the arc-shaped block 5 to the slot block 2.
[0018] The denture mounting block 4 is rotatably connected to the arc-shaped block 5 via the fixing rod 20, and the angle can be adjusted as needed. Pulling the pull ring 9 causes the locking rod 11 to slide outward, compressing the spring 19. Then, aligning the slot 12 of the fixing rod 20 with the locking rod 11, the pull ring 9 is released, and the locking rod 11 is inserted into the slot 12 under the action of the spring force, locking the denture mounting block 4.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
