Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0023] As Figures 1 to 6 shown, a connecting member for a fixed denture in this embodiment includes a bottom plate 1. A fixing plate 19 is connected to one side surface of the bottom plate 1. A connecting plate 18 can be detachably installed on one side surface of the bottom plate 1 and one side surface of the fixing plate 19. A sliding hole 2 is opened in the upper part of one side surface of the connecting plate 18. A sliding block 3 is slidably connected inside the connecting plate 18. One end of the sliding block 3 penetrates through the sliding hole 2 and extends to the outside of the connecting plate 18. A movable snap ring 4 is connected to the extending end of the sliding block 3. A fixed snap ring 5 is connected to one side surface of the connecting plate 18 below the movable snap ring 4. By placing the fixing plate 19 between the movable snap ring 4 and the fixed snap ring 5 of another bottom plate 1, and making one side surface of the fixing plate 19 contact the fixed snap ring 5, then moving the movable snap ring 4 until the movable snap ring 4 contacts the other side surface of the fixing plate 19 and the second threaded hole 7 is aligned with a first threaded hole 6, and by rotating the first bolt 8, inserting the first bolt 8 into the second threaded hole 7 and the first threaded hole 6, the movable snap ring 4 and the fixed snap ring 5 clamp the fixing plate 19.

[0024] Specifically, a first threaded hole 6 is provided in the upper part of the top end of the connecting plate 18, and a second threaded hole 7 is provided in the top end of the slider 3. A first bolt 8 is threadedly connected to the interiors of both the first threaded hole 6 and the second threaded hole 7. By rotating the first bolt 8 and inserting the first bolt 8 into the second threaded hole 7 and the first threaded hole 6, the movable snap ring 4 is fixed.

[0025] Further, a second bolt 20 is threadedly connected to the inner cavity in the middle of the connecting plate 18. One end of the second bolt 20 penetrates through the connecting plate 18 and extends into the fixing plate 19, and the second bolt 20 is threadedly connected to the fixing plate 19. By rotating the second bolt 20, the second bolt 20 is taken out from the interiors of the connecting plate 18 and the fixing plate 19, so that the connecting plate 18 and the fixing plate 19 are separated, and one connecting plate 18 is removed from one side of the bottom plate 1; a first sliding groove 9 is provided in the bottom plate 1, a fixing column 10 is connected to the top end of the bottom plate 1 above the first sliding groove 9, a second sliding groove 11 is provided in the fixing column 10, and the first sliding groove 9 is communicated with the second sliding groove 11, so that the sliding column 12 can move inside the first sliding groove 9 and the second sliding groove 11; a sliding column 12 is movably connected to the interiors of both the first sliding groove 9 and the second sliding groove 11. The sliding column 12 is in an inverted T shape. One end of the lower part of the sliding column 12 is connected to a spring 13 inside the first sliding groove 9, and one end of the spring 13 is connected to one side surface inside the first sliding groove 9. The elastic force generated during the springback process of the spring 13 drives the sliding column 12 back to its original position; a limiting block 14 is connected to one side surface of the sliding column 12, and a through hole 15 is provided in the side wall of the fixing column 10 on one side of the limiting block 14. The inner diameter of the through hole 15 is larger than the outer diameter of the limiting block 14, and the limiting block 14 can move from the inside of the fixing column 10 to the outside of the fixing column 10 through the through hole 15.

[0026] Furthermore, a denture 16 is detachably sleeved on the top end of the bottom plate 1 outside the sliding column 12. A slot is provided at the bottom end of the denture 16, and a limiting hole 17 is provided in one side surface inside the slot. The inner diameter of the limiting hole 17 is larger than the outer diameter of the limiting block 14. By moving the limiting block 14 into the limiting hole 17, the denture 16 is fixed on the top end of the bottom plate 1.

[0027] The usage method of this embodiment is as follows: When it is necessary to wear two or more dentures 16, by rotating the second bolt 20, the second bolt 20 is taken out from inside the connecting plate 18 and the fixing plate 19, so that the connecting plate 18 and the fixing plate 19 are separated. One connecting plate 18 is removed from one side of the bottom plate 1, and then the fixing plate 19 is placed between the movable snap ring 4 and the fixed snap ring 5 of another bottom plate 1, and one side surface of the fixing plate 19 is made to contact the fixed snap ring 5. Then, the movable snap ring 4 is moved until the movable snap ring 4 contacts the other side surface of the fixing plate 19, and the second threaded hole 7 is aligned with one first threaded hole 6. By rotating the first bolt 8, the first bolt 8 is inserted into the second threaded hole 7 and the first threaded hole 6, so that the movable snap ring 4 and the fixed snap ring 5 clamp the fixing plate 19, thereby enabling the splicing and installation of two or more bottom plates 1, so that two or more dentures 16 can be worn between two natural teeth. After multiple bottom plates 1 are spliced, the two natural teeth are respectively clamped by two groups of movable snap rings 4 and fixed snap rings 5, so that the bottom plate 1 is fixed between the two natural teeth. Then, the denture 16 is moved downward along the fixed column 10. Since the end of the limiting block 14 away from the sliding column 12 is arranged in an inclined surface, during the downward sliding of the denture 16, the limiting block 14 will be pushed towards the end close to the spring 13, so that the limiting block 14 slides along the through hole 15 towards the side close to the spring 13, thereby driving the sliding column 12 to press the spring 13. Then, the denture 16 is further moved downward until the limiting hole 17 is aligned with the limiting block 14. The sliding column 12 moves towards the side away from the spring 13 under the action of the elastic force of the spring 13, thereby driving the limiting block 14 to be clamped into the limiting hole 17 along the through hole 15, so that the denture 16 is fixed, thus completing the wearing of the denture 16.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
