Detailed Description

To achieve the above objects and advantages, the present invention provides a technical means and a structure, which will be described in detail with reference to the accompanying drawings, so as to fully understand the features and functions of the preferred embodiments of the present invention.

Referring to fig. 1 to 3, it can be clearly seen that the present invention includes:

a combination seat body 1 for combining on a tooth surface;

a dental arch wire casing 11 formed on the combination seat body 1;

a through hole 12 formed on the combination base 1 and located at one side of the dental arch wire casing 11;

a sliding cover component 2 arranged on the combined seat body 1 in a sliding way for sealing the opening of the dental arch wire casing 11;

a positioning groove 3 arranged at the inner side of the sliding closure component 2, wherein the positioning groove 3 comprises a sliding part 31 and at least one positioning concave part 32 formed at the end of the sliding part 31;

at least one damping member 33 defined in the sliding cover assembly 2 and located at one side of the positioning slot 3;

a movable guiding member 4 movably disposed on the through hole portion 12 and the positioning groove 3; and

a sealing member 5 disposed at the bottom of the combination base 1 for sealing the through hole 12.

With the above description, the structure of the present technology can be understood, and according to the corresponding cooperation of the structure, the advantages of smooth movement and fixed strength of the sliding cover assembly 2, reduced abrasion of the movable guide 4 and the positioning groove 3, stable repeated opening and closing function, and high assembly convenience can be provided, and the detailed description will be described below.

Referring to fig. 1 to 8, when the above components are assembled, as can be seen clearly from the drawings, the appearance of the present invention is similar to that of a general dental appliance, but the component providing the elasticity of the sliding cover component 2 is formed by combining the movable guide 4, the damping member 33 (the damping member 33 of the present embodiment is integrally formed on one side of the positioning groove 3), and the sealing member 5, and the assembly method of the above components is very simple and fast, specifically, as shown in fig. 4, the combined base 1 of the present embodiment is made of metal, so the combined base 1, the dental arch wire groove 11, and the perforated portion 12 are all integrally formed, when assembling, the movable guide 4 (the movable guide 4 of the present embodiment is made of a ball as an example) and the sealing member 5 are assembled from the perforated portion 12 of the bottom of the combined base 1, and finally the combined base 1 and the sealing member 5 are fixed by laser welding, the through hole 12 is closed to complete the assembling operation.

In actual use, as shown in fig. 5, the bottom of each combination seat body 1 is respectively adhered to the surface of each tooth (i.e. tooth surface 7) of a patient, then the dental arch wire 71 is placed in the dental arch wire groove 11, and after the user adjusts the dental arch wire 71, the user applies force to one side of the sliding cover component 2 to displace the sliding cover component towards the opening of the dental arch wire groove 11 so as to close the opening of the dental arch wire groove 11, thereby fixing the dental arch wire 71.

Specifically, as shown in fig. 6 and 7, the closing operation of the slide cover assembly 2 is moved from the open state to the closed state. When the sliding cover assembly 2 is in the open state, the movable guiding member 4 is located in the sliding portion 31 of the positioning slot 3, the sliding portion 31 is a smooth surface or a circular arc surface with a shallow depth, which not only provides the effect of smooth displacement (relative displacement with the sliding cover assembly 2) of the movable guiding member 4, but also generates a downward extrusion pressure on the damping member 33 due to the depth, and at this time, the damping member 33 generates obvious deformation due to its own flexibility, so that the damping member 33 accumulates a certain degree of elasticity. When the movable guiding element 4 moves to the positioning concave part 32 of the positioning slot 3, the sliding cover assembly 2 is in a closed state, because the depth of the positioning concave part 32 is greater than the depth of the sliding part 31, and the shape of the positioning concave part 32 is approximately matched with the surface of the movable guiding element 4, the accumulated elastic force is released by the positioning concave part 32 and the movable guiding element 4, and the damping element 33 is matched to push the movable guiding element 4, so that the movable guiding element 4 is reliably fixed in the positioning concave part 32, and the purpose of limiting the sliding cover assembly 2 is completed (please refer to fig. 2).

Therefore, even if the orthodontic treatment course is long and the repeated opening and closing times are more, the wear problem between the movable guide 4 and the positioning groove 3 can be alleviated through the design of the damping piece 33.

In addition, as shown in fig. 8, since the positioning slot 3 has only one positioning recess 32 in the embodiment, when the sliding cover assembly 2 is in the open state, there is a risk of being disengaged from the combination base body 1 if the operation is careless, so a limit post 15 is inserted into the combination base body 1 to abut against the limit groove 22 of the sliding cover assembly 2 (the limit groove 22 is formed at one side of the positioning slot 3), and the purpose of preventing the sliding cover assembly 2 from being disengaged is achieved by the cooperation of the limit post 15 and the limit groove 22.

As shown in fig. 9 to 11, it is clear that the embodiment is the same as the above embodiment, and only the damping member 33a is additionally disposed in the groove 21a of the sliding cover assembly 2a, so that the sliding cover assembly 2a or the positioning groove 3a is made of one of metal, polymer or ceramic, and thus has no deformation capability and depends on the deformation of the damping member 33 a. Therefore, the sealing part 5a arranged below the movable guide part 4a can be matched to support and limit, and the damping part 33a arranged above can contract and deform, so that the abrasion resistance of the sliding cover component 2a is increased. Or as shown in fig. 9, the closing member 5a has at least one fixing member 6a disposed in the through hole portion 12a and located on a side of the movable guide 4a facing away from the sliding cover assembly 2a, so as to provide another form of supporting the movable guide 4 a.

In addition, at least one accommodating portion 13a is formed at the bottom of the combination seat body 1a, so that the colloid coated on the combination seat body 1a when being adhered to the tooth surface of the patient can contact the combination seat body 1a in a larger area, thereby increasing the adhesion strength of the combination seat body 1 a. In addition, in the present embodiment, the number of the positioning concave portions 32a is increased to two, and the two positioning concave portions 32a are respectively formed at the two ends of the sliding portion 31a, so that the movable guide 4a can be fixed in the positioning concave portions 32a no matter the sliding cover assembly 2a is in the open state or the closed state.

As shown in fig. 12 to 14, it is clear that the embodiment is different from the above embodiments in that the material of the combination seat body 1b is changed to ceramic, and the fixing member 6b of the embodiment includes a ring-shaped supporting portion 61b, a penetrating portion 62b formed at the center of the ring-shaped supporting portion 61b, and a limiting member 63b disposed at an end of the ring-shaped supporting portion 61b opposite to the movable guiding member 4 b. During assembly, the combination base body 1b, the dental arch wire slot 11b and the through hole 12b are still integrally formed, so long as the movable guide 4b, the annular support portion 61b and the limiting member 63b are sequentially installed from the through hole 12b at the bottom of the combination base body 1b, and finally the light-cured resin (i.e., the sealing member 5b) is coated on one side of the limiting member 63b and the through hole 12b is sealed, so that the assembly operation is completed, as shown in fig. 14, the spherical limiting member 63b is matched to provide the positioning effect of the movable guide 4b, and simultaneously, the sealing effect of the sealing member 5b is increased by using a larger spherical area.

The annular support portion 61b is disposed between the movable guide 4b and the limiting member 63b, so that the movable guide 4b can normally provide a supporting and limiting effect without being affected by the closing member 5b, and at this time, the movable guide 4b is partially disposed in the penetrating portion 62b, so that a stable supporting force and a limiting effect can be obtained by utilizing the hollow shape of the annular support portion 61 b.

The closing member 5b has at least one combining portion 51b on one side thereof, and the bottom of the combining base 1b has at least one abutting portion 14b correspondingly combined with the combining portion 51 b. Therefore, during assembly, the movable guide 4b, the fixing member 6b, and the limiting member 63b are also sequentially placed into the through hole 12b, and the sealing member 5b is covered at the bottom of the coupling seat 1b, and the sealing member 5b and the coupling seat 1b are fixed in this embodiment by using a large number of concave-convex fastening structures, so as to provide a stable coupling force between the sealing member 5b and the coupling seat 1b, or the coupling portion 51b is designed in a hook shape, the abutting portion 14b is designed in a groove shape, and the coupling portion 51b and the abutting portion 14b are respectively placed at the side edges of the sealing member 5b and the coupling seat 1b, so as to be fixed from the outer side edge.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, so that the contents of the specification and the drawings are simplified and the equivalent structure changes are all included in the scope of the present invention.
