[0026] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to be able to fully convey the scope of the present invention to those skilled in the art.

[0027] As Figures 1 to 3 shown, the present invention provides a wearing device for a hook denture. A pair of hooks 2 are respectively arranged at both ends of the hook denture 1, including:

[0028] A base 3, a sliding groove is arranged inside the base 3, support portions are respectively arranged at both ends of the base 3, and a protruding top block 4 is arranged in the middle of the base 3. The top block 4 is used to contact the denture.

[0029] A slide block 5, which is slidably arranged in the sliding groove. A pressing block 6 extending out of the base 3 is arranged on one side of the slide block 5, and a wedge-shaped convex block 7 is respectively arranged at both ends of the other side of the slide block 5.

[0030] Two pairs of movable plates 8 are respectively arranged on both sides of the top block 4. The middle of each movable plate 8 is rotatably connected to the support portion through a rotating shaft 9. One end of each movable plate 8 is S-shaped and its outer end turns outwards. The other end of each movable plate 8 is provided with an inward protruding protruding portion 10. One end of each pair of movable plates 8 can be inserted into a pair of hooks 2. The wedge-shaped surface 11 of the wedge-shaped convex block 7 cooperates with the protruding portion 10 at the other end of the movable plate 8, so that when the pressing block 6 is pressed, the movement of the slide block 5 and the wedge-shaped convex block 7 relative to the base 3 can drive the two pairs of movable plates 8 to rotate.

[0031] Specifically, to solve the problems of inconvenient wearing of the hook denture 1 and lack of wearing operation tools in the prior art; the wearing device of the hook denture provided by the present invention is provided with two pairs of movable plates 8 at both ends of the upper side of the base 3, and each movable plate 8 is rotatably connected to the supporting part on the base 3 through a rotating shaft 9. A space capable of accommodating a healthy tooth 17 is formed between a pair of movable plates 8, and a space capable of accommodating the hook denture 1 is formed between the two pairs of movable plates 8. One end of each pair of movable plates 8 can be inserted between a pair of hooks 2 of the hook denture 1, and the top block 4 on the base 3 can abut and limit the hook denture 1. Since one end of the movable plate 8 is S-shaped and its outer end turns outwards, when installing the hook denture 1 through the wearing device of the hook denture, after the hook denture 1 is placed in the wearing device of the hook denture, the hook 2 is at the first bending position of one end of the movable plate 8. The operator can hold the wearing device of the hook denture and put it into the oral cavity. Guided by the outwards-turning structure of one end of the movable plate 8, the base 3 and the movable plate 8 move towards the gingiva side to be worn. The top block 4 pushes the hook denture 1. After moving in place, the index finger and middle finger can clamp the base 3, and the thumb presses the pressing block 6. Under the pressing action, the slider 5 moves towards the gingiva. The wedge surface 11 of the wedge-shaped convex block 7 cooperates with the protruding part 10 of the other end of the movable plate 8, so that the two pairs of movable plates 8 rotate. One end of the movable plates 8 on both sides of the hook denture 1 rotates. At the same time, the index finger and middle finger clamp the base 3 to move the base 3 outwards. With the pressing of the pressing block 6 and the outward movement of the base 3, the hook 2 falls off the movable plate 8 and hangs on the healthy teeth 17 on both sides of the hook denture 1, realizing the convenient wearing of the hook denture 1. Wearing the hook denture 1 through the wearing device of the hook denture is not only convenient to operate, but also can avoid scratching the healthy teeth 17 or the gingiva by the hook 2 as much as possible, and the wearing effect is good.

[0032] In this embodiment, wedge surfaces 11 are provided on both sides of the end of the wedge-shaped convex block 7 away from the slider 5.

[0033] Optionally, the supporting part includes a fixing part 12 and an assembling part 13. The fixing part 12 is fixedly connected to the base 3. Both ends of the assembling part 13 can be detachably connected to the fixing part 12. The rotating shaft 9 is rotatably connected to the assembling part 13. The other end of each movable plate 8 is set to be S-shaped and its outer end buckles inwards. The other end of each pair of movable plates 8 can wrap around a pair of hooks 2.

[0034] Specifically, the supporting part includes two parts, a fixing part 12 fixed on the base 3 and an assembling part 13 detachably installed on the fixing part 12. In this way, the assembling part 13 can be detached from the fixing part 12 together with the rotating shaft 9 and the movable plate 8. Since both ends of the assembling part 13 can be connected to the fixing part 12, the movable plate 8 can be turned over when it is necessary to disassemble the hook denture 1, so that one end of the movable plate 8 is close to the base 3, and the other end of the movable plate 8 is used to wrap around the hook 2, asFigure 4 As shown, since the other end of the movable plate 8 is S-shaped and its outer end is buckled inward, it can hook the hooks 2 on both sides of the healthy tooth 17. When the hooks 2 are hooked, the hooks 2 can be conveniently removed from the healthy tooth 17 by pulling, realizing the convenient disassembly of the hook denture 1.

[0035] In this embodiment, the assembly part 13 and the fixing part 12 can adopt a connection method of inserting a convex block and fastening with a side set screw. While being detachable, the connection is ensured to be stable.

[0036] Optionally, it further includes a pair of pressing plates. Each pressing plate includes a T-shaped main board body 14. One end of the main board body 14 is provided with a bent connecting plate 15. The bent connecting plate 15 is connected to the top block 4. The other two ends of the main board body 14 are respectively arranged on the outer sides of the two movable plates 8.

[0037] Specifically, one end of the main board of each T-shaped pressing plate is a connecting end, which realizes elastic deformation when connecting and pressing on the side of the top block 4. The other two ends of the main board of each T-shaped pressing plate respectively extend to the outer sides of one movable plate 8 in each of the two pairs of movable plates 8. In this way, as long as the middle part of the T-shaped main board body 14 is pressed, the two pairs of movable plates 8 can be pressed simultaneously, and the two pairs of hooks 2 can be removed from the healthy tooth 17 at the same time.

[0038] Optionally, a pressing part is arranged at the T-shaped intersection of the main board body 14, and the surface of the pressing part is provided with uneven first anti-slip textures 16.

[0039] Specifically, the setting of the first anti-slip textures 16 can increase the friction at the pressing position, and it is convenient for the thumb and index finger to pull the whole wearing device of the hook denture outward when pressing a pair of pressing plates.

[0040] Optionally, the base 3 is strip-shaped, and uneven second anti-slip textures are respectively arranged on both sides of the base 3.

[0041] Specifically, the shape of the base 3 is similar to a rectangle, but the outer shape of the base 3 still needs to be set according to the tooth arrangement situation, so that the space between the two pairs of movable plates 8 on the upper side of the base 3 matches the positions of the healthy teeth 17 on both sides of the missing tooth, and the middle space on the upper side of the base 3 between the two pairs of movable plates 8 matches the position of the missing tooth; the setting of the second anti-slip textures on both sides of the base 3 can increase the friction at the clamping position of the index finger and middle finger, and it is convenient for the index finger and middle finger to stably clamp the base 3 and move the base 3 outward when the thumb presses the pressing block 6.

[0042] In this embodiment, both side surfaces of the base 3 are covered with second anti-slip textures.

[0043] Optionally, the fixing part 12 is columnar, and the four fixing parts 12 are respectively arranged at the four corners of the base 3. The assembling part 13 is columnar, and both ends of the rotating shaft 9 are respectively rotatably connected to an assembling part 13.

[0044] Specifically, both the fixing part 12 and the assembling part 13 are columnar, and they are detachably connected to facilitate turning over the movable plate 8, so as to realize the wearing function of the hook denture 1 while realizing the disassembly function of the hook denture 1; the two assembling parts 13 at the same end of the base 3 may not be connected, and the two assembling parts 13 on the same side of the base 3 are connected by the rotating shaft 9; alternatively, the two assembling parts 13 at the same end of the base 3 can be connected by a steel wire that can pass through the dental space to improve the integrity of the disassembly part.

[0045] Optionally, the movable plate 8 is a stainless steel plate.

[0046] Specifically, the thickness and stiffness of the movable plate 8 need to be set according to actual needs, and it needs to be as thin as possible while ensuring a certain support stiffness.

[0047] Optionally, the top view projection shapes of both ends of the movable plate 8 match the top view projection shape of the hook 2 of the hook denture 1.

[0048] Specifically, as Figure 3 and Figure 4 shown, the movable plate 8 not only has a structure with both ends being S-shaped in cross-section, but also in the top view projection direction, the shapes of both ends of the movable plate 8 match the bending shape of the hook 2. In this way, when wearing, the movable plate 8 can fit more closely with the hook 2, making it easy to wear. And after multiple disassembly, if the hook 2 undergoes some deformation and causes loosening during wearing, the hook denture 1 and its hook 2 can be placed in the wearing device of the hook denture, so that the two pairs of hooks 2 are respectively located between the other ends of the two pairs of movable plates 8. By squeezing a pair of pressing plates, the hook 2 is shaped in an overcorrection manner, making the distance between each pair of hooks 2 slightly smaller, and thus making it more stable after the next wearing.

[0049] Optionally, the stiffness of the main board body 14 is greater than the stiffness of the bent connecting plate 15.

[0050] Specifically, the main board body 14 needs to transmit the pressure at the pressing part position to the other two ends of the main board body 14, so that the two pairs of movable plates 8 move inwards, so a large stiffness is required. While the bent connecting plate 15 undergoes elastic deformation during this process and does not require a large stiffness.

[0051] Optionally, the thickness of the bent connecting plate 15 is less than the thickness of the bent connecting plate 15.

[0052] Specifically, it can be made easy to deform by gradually thinning the thickness of the bending connection plate 15, and the stiffness of the main board body 14 is ensured to meet the pressing force transmission requirements.

[0053] In summary, the wearing device for the clasp denture provided by the present invention can be adaptively designed according to the specific situation of the clasp denture 1. For example, it can be provided in a supporting manner when the user obtains the clasp denture 1. It can not only facilitate the wearing of the clasp denture 1, but also facilitate the disassembly of the clasp denture 1 by turning over the movable plate 8, making the disassembly and assembly of the clasp denture 1 very simple. The wearing device for the clasp denture is small and portable, and is convenient for cleaning and storage, and can be placed in a denture storage box together with the clasp denture 1.

[0054] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
