Description

Technical Field

[0001] The invention relates to the field of glasses, and in particular to a fully enclosed hinge and glasses. Background Art

[0002] With the advancement of modern eyewear design and manufacturing technology, consumers have put forward higher requirements for the aesthetics, comfort and durability of glasses. Among them, the performance of eyeglass hinges, as an important part of the eyeglass frame, directly affects the wearing experience and service life of the glasses. Traditional eyeglass hinges are mostly connected by screws. Although this structure has certain flexibility, it also has obvious disadvantages:

[0003] Traditional screw hinge structures usually have many gaps, which easily accumulate dust and foreign matter, not only affecting the appearance, but also causing the hinge to rotate unsmoothly.

[0004] Hinges connected by screws can easily loosen due to vibration or daily handling during long-term use, which can affect the stability of the glasses and even cause discomfort or damage, increasing the need for after-sales service.

[0005] The processing and assembly of traditional hinges requires high precision and involves multiple steps, which increases production costs.

[0006] In order to solve the above problems, some improved fully enclosed hinges have been proposed. These designs have optimized the structure to a certain extent and improved dust resistance and stability. However, these improved solutions often have problems such as complex assembly or difficult processing, which makes it difficult to meet the market demand for lightness, beauty and low cost. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a fully enclosed hinge and glasses, which adopt simple structural assembly, which not only improves the aesthetics and smoothness of the hinge, but also realizes a light and comfortable wearing experience, reduces production difficulty and cost, and further improves the stability and durability of the hinge.

[0008] The present invention is realized by the following technical scheme: a fully enclosed hinge, comprising:

[0009] A glasses leg, wherein a first rotating connection portion is provided at one end of the glasses leg;

[0010] A glasses head, wherein one end of the glasses head is provided with a second rotating connection part, and the first rotating connection part is located at the bottom of the first rotating connection part;

[0011] A snap-fitting component is arranged on the lower end surface of the eyeglass head, and the snap-fitting component passes through the eyeglass head and the eyeglass legs at the upper end in sequence.

[0012] As a preferred technical solution, a rotating part is provided on the top of the snap-on component, and a rotating shaft hole is provided on the first rotating connecting part and the second rotating connecting part corresponding to the rotating part, and the snap-on component passes through the rotating shaft hole in sequence through the rotating part.

[0013] As a preferred technical solution, a rotation limiting part is also provided on the snap-fitting part on one side of the rotating part, and a rotation limiting groove is provided on one side of the rotating shaft hole of the second rotating connecting part corresponding to the rotation limiting part. The rotation limiting part is located in the rotation limiting groove and can rotate within the limited range of the rotation limiting groove.

[0014] As a preferred technical solution, the outer cylindrical surface of the rotating part is provided with a positioning recess, the inner wall surface of the shaft hole of the first rotating connecting part is provided with a positioning protrusion corresponding to the positioning recess, and the positioning recess is positioned and assembled with the positioning protrusion.

[0015] As a preferred technical solution, after the positioning recess is positioned and installed in the positioning shaft hole, the positioning recess is fixed by stamping and flanging.

[0016] As a preferred technical solution, it also includes a gasket, which is installed between the first rotating connection part and the second rotating connection part.

[0017] As a preferred technical solution, the gasket is a T-shaped gasket, the bottom of the gasket has an extension portion, and the extension portion is inserted into the shaft hole on the second rotating connecting part.

[0018] The spectacles of the present invention include a fully enclosed hinge.

[0019] The beneficial effects of the present invention are as follows: the fully enclosed hinge proposed by the present invention realizes the tight assembly of the hinge assembly through the snap-fit ​​parts and the gasket structure, avoids the problem of loosening of the temple of the glasses due to loose screws in the traditional hinge structure, and significantly improves the overall stability and service life;

[0020] The fully enclosed structure of the hinge effectively prevents the entry of dust and foreign matter, ensuring the hinge's aesthetics and smoothness for long-term use, and reducing the jamming problem caused by wear;

[0021] In addition, the gasket in the hinge adopts a T-shaped design, which has precise positioning and shaft limiting functions, making the hinge more stable and smooth during rotation, further reducing the possibility of mechanical friction and structural looseness;

[0022] At the same time, the structure simplifies the assembly process, reduces production costs, and is suitable for mass industrial production. Due to the compact structure and lightweight design of the hinge, it is particularly suitable for the application of small glasses legs, thereby greatly improving the wearing comfort and fashionable appearance of glasses, meeting consumers' diverse needs for high-quality glasses, and almost realizing post-retail maintenance.

DETAILED DESCRIPTION

[0031] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0032] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0033] like Figure 1and Figure 5 As shown, the present invention proposes a fully enclosed hinge, wherein one end of the eyeglass leg 1 is provided with a first rotating connection portion 2, and the rotating connection portion is used to realize a hinge connection with one end of the eyeglass head 6;

[0034] A second rotating connection part 5 is provided at one end of the eyeglass head 6, and the first rotating connection part 2 is located at the bottom of the second rotating connection part 5, forming a structure of upper and lower docking; through this upper and lower distributed connection method, the coordination between the eyeglass leg 1 and the eyeglass head 6 is effectively simplified, and the stability of the structure is improved.

[0035] In order to achieve a tighter connection and assembly, the snap-fit ​​component 10 is designed as a key component. The snap-fit ​​component 10 is installed on the lower end surface of the eyeglass head 6, and passes through the eyeglass head 6 and the upper end of the eyeglass leg 1 in sequence to complete the connection between the two. A rotating part 9 is provided on the top of the snap-fit ​​component 10, and the rotating part 9 cooperates with the corresponding shaft holes 3 on the first rotating connection part 2 and the second rotating connection part 5. The rotating part 9 of the snap-fit ​​component 10 passes through these shaft holes 3 in sequence to ensure the flexibility and stability of the eyeglass leg 1 and the eyeglass head 6 during the rotation process.

[0036] Furthermore, in order to limit the rotation range of the hinge and prevent excessive rotation, a rotation limiter 8 is provided on one side of the rotation portion 9 of the buckle vehicle component 10. Figure 3 As shown, a rotation limiting groove 51 matched with the rotation limiting portion 8 is provided on one side of the rotation shaft hole 3 of the second rotation connection portion 5 .

[0037] The rotation limiting portion 8 is accommodated in the rotation limiting groove 51 and can realize rotation within a limited range in the groove. This design effectively prevents the hinge from being damaged due to excessive rotation during use, thereby improving the durability of the product.

[0038] Among them, a positioning recess 7 is provided on the outer cylindrical surface of the rotating part 9, and a positioning protrusion 21 corresponding to the positioning recess 7 is provided on the inner wall surface of the rotating shaft hole 3 of the first rotating connecting part 2. The positioning recess 7 is positioned and assembled with the positioning protrusion 21. After the positioning recess 7 is positioned and installed in the positioning shaft hole 22, the positioning recess 7 is fixed by stamping and flanging to further enhance the tightness and stability of the hinge structure.

[0039] In this embodiment, the positioning recesses are arranged to be two symmetrical ones, and the number of the positioning protrusions is the same as that of the positioning recesses. During assembly, the positioning protrusions are positioned and assembled with the positioning recesses, and then the stability of the hinge can be ensured and shaking can be prevented after stamping and flanging.

[0040] In order to solve the friction problem during the hinge rotation process, the present invention designs a gasket 4 structure. The gasket 4 is installed between the first rotating connection part 2 and the second rotating connection part 5, which can effectively reduce the direct contact between the two, reduce the friction force, and improve the smoothness of the rotation.

[0041] like Figure 4 As shown, the gasket 4 is preferably a T-shaped gasket 4, and an extension portion 41 is designed at the bottom thereof, and the extension portion 41 can be inserted into the shaft hole 3 on the second rotating connecting portion 5. The outer diameter of the extension portion 41 is equal to the inner diameter of the shaft hole 3, thereby ensuring a close fit between the gasket 4 and the shaft hole 3, and further improving the stability of the hinge rotation.

[0042] The fully enclosed hinge structure of the present invention has multiple advantages over the traditional design. On the one hand, its fully enclosed structure effectively prevents the entry of dust and foreign matter, ensures the aesthetic appearance of the hinge, and also prolongs the service life; on the other hand, the design of the gasket 4 and the optimization of the buckle 10 enable the hinge to remain smooth and stable during long-term use and not easy to loosen.

[0043] In addition, the structure simplifies the assembly process, reduces the difficulty and cost of production, and is particularly suitable for the design and production of thin glasses legs 1, greatly improving the wearing comfort and fashion appearance of glasses. The present invention realizes high-quality glasses hinge products close to retail, providing reliable technical support for modern glasses manufacturing.

[0044] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
