Description

Technical Field

[0001] The present application relates to the field of dentures, and in particular to an anti-loosening telescopic crown denture. Background Art

[0002] Telescopic dentures are a combination fixed and removable restoration. They consist of a highly secure inner and outer crown. During installation, the inner crown is bonded to the abutment tooth, while the outer crown is placed inside the denture. The friction generated by the tight fit between the inner and outer crowns holds the denture in place. However, typical telescopic crowns can become loose during use, impacting the consumer experience.

[0003] Existing telescopic dentures are mainly connected by hook-like buckles during installation. This connection method will cause greater wear during long-term use, which will cause the denture to become loose easily. Once the denture becomes loose, it will directly lead to increased wear of the denture, which will directly affect the normal use of the denture. Utility Model Content

[0004] In order to solve the problem that existing telescopic crown dentures are prone to loosening, the present application provides an anti-loosening telescopic crown denture.

[0005] The present application provides an anti-loosening telescopic crown denture adopting the following technical solution:

[0006] A non-loosening telescopic crown denture comprises a tooth body, a connecting component mounted on the tooth body, a clamping component clamped on the connecting component and a denture mounted on the clamping component, wherein the connecting component comprises a clamping seat fixedly connected to the tooth body, and a through groove is provided on an outer wall of one side of the clamping seat, an installation cavity is provided inside the clamping seat, and an opening is provided on an inner wall of one side of the installation cavity, and an L-shaped connecting seat is slidably connected to the inner wall of the opening.

[0007] By adopting the above technical solution, the connecting component on the tooth body and the clamping component on the denture are engaged with each other, thereby facilitating the installation of the denture. The setting of the mounting cavity in the clamping seat facilitates the sliding installation of the L-shaped connecting seat.

[0008] The inner walls on both sides of the installation cavity are rotatably connected to a same bidirectional screw, and the outer wall of the bidirectional screw is threadedly connected to two symmetrically arranged threaded sleeves.

[0009] By adopting the above technical solution, the bidirectional screw can be rotated conveniently through the setting of the installation cavity, and when the bidirectional screw rotates, it is convenient to directly drive the two threaded sleeves to move toward or away from each other.

[0010] The outer walls of the two threaded sleeves are rotatably connected to a connecting plate, and one end of the two connecting plates is rotatably connected to a sliding seat, and the sliding seat is slidably connected to the inner wall of the installation cavity.

[0011] By adopting the above technical solution, the threaded sleeve is driven to move when the bidirectional screw rotates, and the threaded sleeve can directly drive the connecting plate to move when it moves, and the connecting plate can directly drive the sliding seat to move when it moves.

[0012] The sliding seat is fixedly connected to the L-shaped connecting seat, a circular groove is provided on the outer wall of the top of the clamping seat, and a rotating part is rotatably connected to the inner wall of the bottom of the circular groove. The transmission shaft of the rotating part is fixedly connected to the bidirectional screw, a sealing cover is clamped on the inner wall of the circular groove, and a clamping groove is provided on the inner wall of one side of the through groove.

[0013] By adopting the above technical solution, when the sliding seat slides in the installation cavity, it is convenient to directly drive the L-shaped connecting seat to move. The circular groove on the clamping seat facilitates the hidden installation of the rotating part. The setting of the rotating part facilitates the direct rotation of the bidirectional screw. The setting of the sealing cover facilitates the closing of the circular groove, thereby facilitating the protection of the rotating part.

[0014] The clamping assembly includes a connecting seat fixedly connected to the denture, and a rectangular seat is fixedly connected to an outer wall of one side of the connecting seat, and the rectangular seat is slidably connected to the inner wall of the clamping slot.

[0015] By adopting the above technical solution, the rectangular seat on the connecting seat is inserted into the clamping slot, thereby facilitating the clamping of the connecting seat on the clamping seat.

[0016] The specification of the card slot is larger than that of the rectangular seat.

[0017] By adopting the above technical solution, the width of the card slot is greater than the width of the rectangular seat, thereby facilitating the horizontal sliding of the rectangular seat in the card slot.

[0018] One side outer wall of the connecting seat is fixedly connected to two symmetrically arranged U-shaped seats, and the specifications of the U-shaped seats match those of the L-shaped connecting seat.

[0019] By adopting the above technical solution, the U-shaped seat on the connecting seat is conveniently connected to the L-shaped connecting seat on the clamping seat, and when the L-shaped connecting seat moves, the U-shaped seat is directly pulled to move.

[0021] 1. This application provides a connecting assembly on the tooth body and a clamping assembly on the denture. The cooperation between the clamping assembly and the connecting assembly facilitates the fixation of the denture. At the same time, the adjustable L-shaped connecting seat in the connecting assembly facilitates the tightening of the clamping seat, thereby effectively preventing the denture from loosening.

[0022] 2. This application facilitates direct pulling of the L-shaped connecting seat by setting a bidirectional screw, a threaded sleeve and a connecting plate in the clamping seat. The setting of the rotatable part in the clamping seat facilitates direct rotation of the bidirectional screw, thereby facilitating manual adjustment of the L-shaped connecting seat.

The inner wall of the opening is slidably connected to the L-shaped connecting seat 2-5, and the inner walls on both sides of the mounting cavity 5 are rotatably connected to the same bidirectional screw 6, and the outer wall of the bidirectional screw 6 is screwed with two symmetrically arranged threaded sleeves 7, and the two threaded sleeves 7 The outer walls of the two connecting plates 8 are rotatably connected to the connecting plates 8, and one end of the two connecting plates 8 is rotatably connected to the sliding seat 9, the sliding seat 9 is slidably connected to the inner wall of the mounting cavity 5, and the sliding seat 9 is fixedly connected to the L-shaped connecting seat 2-5. A circular groove is provided on the top outer wall of the clamping seat 2-1, and the bottom inner wall of the circular groove is rotatably connected to the rotating part 2-2. The transmission shaft of the rotating part 2-2 is fixedly connected to the bidirectional screw 6. The inner wall of the circular groove is clamped with a sealing cover 2-3, and a clamping groove 2-6 is provided on the inner wall of one side of the through groove 2-4;

[0033] When in use, the circular groove on the clamping seat 2-1 is convenient for concealing the installation of the rotating part 2-2. The setting of the rotating part 2-2 is convenient for directly driving the bidirectional screw 6 to rotate. The setting of the sealing cover 2-3 is convenient for closing the circular groove, thereby conveniently protecting the rotating part 2-2. When the bidirectional screw 6 rotates, it is convenient to directly drive the two threaded sleeves 7 to move toward or away from each other. When the two threaded sleeves 7 move away from each other, the sliding seat 9 is directly pulled toward the bidirectional screw 6 through the connecting plate 8. When the sliding seat 9 moves, it directly pulls the L-shaped connecting seat 2-5 to move. When the two threaded sleeves 7 move toward each other, the sliding seat 9 is directly pushed through the connecting plate 8 to drive the L-shaped connecting seat 2-5 out.

[0034] Reference Figure 3 The clamping assembly 4 installed on the denture 3 includes a connecting seat 4-3 fixedly connected to the denture 3, and one side outer wall of the connecting seat 4-3 is fixedly connected to a rectangular seat 4-2, and the rectangular seat 4-2 is slidably connected to the inner wall of the slot 2-6. The rectangular seat 4-2 on the connecting seat 4-3 is inserted into the slot 2-6, so as to facilitate the connection of the connecting seat 4-3 to the clamping seat 2-1. The specifications of the slot 2-6 are larger than the specifications of the rectangular seat 4-2. The width of the slot 2-6 is larger than the width of the rectangular seat 4-2, which makes it convenient for the rectangular seat 4-2 to slide horizontally in the slot 2-6. One side outer wall of the connecting seat 4-3 is fixedly connected to two symmetrically arranged U-shaped seats 4-1, and the specifications of the U-shaped seat 4-1 match the specifications of the L-shaped connecting seat 2-5. The U-shaped seat 4-1 on the connecting seat 4-3 is conveniently connected to the L-shaped connecting seat 2-5 on the clamping seat 2-1. When the L-shaped connecting seat 2-5 moves, it directly pulls the U-shaped seat 4-1 to move.

[0035] The implementation principle of an anti-loosening telescopic crown denture in the embodiment of the present application is as follows: during use, when the denture 4 needs to be installed, the clamping seat 4-3 on the denture 3 is first vertically inserted into the clamping seat 2-1, the rectangular seat 4-2 is inserted into the clamping groove 2-6, and the U-shaped seat 4-1 is inserted into the L-shaped connecting seat 2-5, and then rotated by the rotating part 2-2. When the rotating part 2-2 rotates, it directly drives the bidirectional screw 6 to rotate. When the bidirectional screw 6 rotates, it directly drives the two threaded sleeves 7 to move toward or away from each other. When the two threaded sleeves 7 move away from each other, the sliding seat 9 is directly pulled toward the bidirectional screw 6 through the connecting plate 8. When the sliding seat 9 moves, it directly pulls the L-shaped connecting seat 2-5 to move. When the L-shaped connecting seat 2-5 moves, it directly tightens the clamping seat 2-1 through the U-shaped seat 4-1, thereby facilitating the tightening and fixing of the denture 3.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
