A fully enclosed hinge for an eyeglass frame

Abstract

The present invention discloses a fully enclosed hinge for an eyeglass frame, which includes a hinge connecting member. The hinge connecting member includes a first rotating portion, a second rotating portion and an intermediate connecting member. The first rotating portion and the second rotating portion are respectively rotatably installed on both sides of the intermediate connecting member. A stud member is installed on one of the rotating portions, and a temple is installed on the other rotating portion. By means of the rotating portions, the stud member and the temple can rotate relative to the intermediate connecting member respectively in its circumferential direction. The present invention utilizes a fully enclosed hinge connecting member, so that the connection strength between the temple of the eyeglass and the stud member is higher, and loosening at the hinged connection can be effectively prevented.

The temple and the stud member are not prone to shaking, and the hinged structure rotates more stably.

Description

Technical Field

[0001] The present invention relates to the technical field of glasses, and particularly relates to a fully enclosed hinge for a spectacle frame. Background Art

[0002] The spectacle frame mainly includes a lens frame, temple arms, and a hinge member. One end of the hinge member is connected to the lens frame, and the other end is hinged to the temple arms through a hinge structure. There are some drawbacks in the traditional hinge structure between the hinge member and the temple arms. For example, the connection is unstable. Since it needs to be frequently opened and folded, the hinge connection is prone to looseness or even detachment, affecting the user experience; the service life is short. The hinge connection is subject to large friction and wears quickly, resulting in a reduced lifespan of the glasses; it is easily affected by the environment. Due to insufficient sealing at the traditional hinge connection, dust and moisture are easy to enter, leading to corrosion or damage of the hinge; it is difficult to repair. Once there is a problem with the hinge structure, such as looseness or damage, it is difficult to repair, and sometimes even the entire spectacle frame needs to be replaced; the temple arms are prone to shaking. The looseness of the hinge structure causes the temple arms to shake, affecting the wearing comfort of the user. Summary of the Invention

[0003] To solve the above problems, the present invention provides a fully enclosed hinge for a spectacle frame. Using a fully enclosed hinge connector significantly improves the quality and structural performance of the glasses. The stable connection between the temple arms and the hinge member greatly reduces the shaking of the glasses, making the rotation of the hinge structure more stable. This structure not only improves the durability of the glasses but also enhances the user's comfort and experience, effectively solving many deficiencies in the prior art.

[0004] The present invention is realized through the following technical solutions: A fully enclosed hinge for a spectacle frame includes a hinge connector. The hinge connector includes a first rotating portion, a second rotating portion, and an intermediate connector. The first rotating portion and the second rotating portion are respectively rotatably installed on both sides of the intermediate connector. A hinge member is installed on one of the rotating portions, and a temple arm is installed on the other rotating portion. The hinge member and the temple arm can rotate relative to the intermediate connector in their circumferential directions by using the rotating portions.

[0005] As a preferred technical solution, the first rotating portion has an assembly extension portion, and a corresponding assembly hole is provided on the second rotating portion corresponding to the assembly extension portion. When the first rotating portion and the second rotating portion are respectively rotatably assembled with the intermediate connector, the assembly extension portion of the first rotating portion passes through the intermediate connector and is rotatably inserted into the assembly hole of the second rotating portion.

[0006] As a preferred technical solution, a limiting bayonet is provided on one side of the cylindrical surface of the assembly extension portion, and a limiting retaining piece is provided in the assembly hole of the second rotating portion. After the assembly extension portion is inserted into the assembly hole, the limiting retaining piece is snapped into the limiting bayonet to prevent the separation of the first rotating portion and the second rotating portion.

[0007] As a preferred technical solution, the upper and lower ends of the intermediate connecting member each have a protruding positioning and assembling portion. Positioning and assembling holes are provided at the positions of the first rotating portion and the second rotating portion corresponding to the positioning and assembling portions. When the first rotating portion and the second rotating portion are respectively installed on both sides of the intermediate connecting member, the first rotating portion and the second rotating portion are respectively hermetically assembled with the intermediate connecting member.

[0008] As a preferred technical solution, a first mounting hole is installed on the first rotating portion, and a second mounting hole is installed on the second rotating portion. One end of the pile head component is fixedly assembled into the first mounting hole, and one end of the temple is fixedly assembled into the second mounting hole.

[0009] As a preferred technical solution, one end of the limiting flap is fixedly installed on the inner wall surface of the assembly hole. The limiting flap is buckled into the limiting bayonet, and the limiting bayonet is formed by circumferentially cutting around the first rotating portion.

[0010] The beneficial effects of the present invention are as follows: The present invention adopts a fully enclosed hinge connecting member to enhance the connection strength between the temple and the pile head component of the glasses. This structure can effectively prevent loosening at the hinge connection. Due to the high sealing performance at the rotating part of the hinge connecting member, dust and moisture are more difficult to penetrate, ensuring that the hinge part of the spectacle frame has a longer service life;

[0011] In addition, due to the stable connection between the temple and the pile head component, the shaking of the glasses will be greatly reduced, making the rotation of the hinge structure more stable. This structure not only improves the durability of the glasses, but also enhances the user's comfort and usage experience. The fully enclosed hinge connecting member significantly improves the quality and structural performance of the glasses. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or features with similar purposes. That is, unless specifically stated, each feature is only an example in a series of equivalent or similar features.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "central", "end portion", "length", "outer end", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0023] In addition, in the description of the present invention, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0024] Spatial relative position terms such as "upper", "above", "lower", "below", etc. used in the present invention are for the purpose of facilitating the description of the relationship between one unit or feature and another unit or feature as shown in the drawings. The spatial relative position terms can be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] As Figure 1 - Figure 2 shown, a fully enclosed hinge for an eyeglass frame according to the present invention includes a hinge connecting member. The hinge connecting member includes a first rotating portion 1, a second rotating portion 10, and an intermediate connecting member 6. The first rotating portion 1 and the second rotating portion 10 are respectively rotatably installed on both sides of the intermediate connecting member 6, and a stud member 4 is installed on one of the rotating portions, and a temple 8 is installed on the other rotating portion. By using the rotating portions, the stud member 4 and the temple 8 can respectively rotate relative to the intermediate connecting member 6 in its circumferential direction. In this embodiment, the stud member 4 is installed on the first rotating portion 1, and the temple 8 is installed on the second rotating portion 10. Therefore, both the stud member 4 and the temple 8 can achieve circumferential rotational movement relative to the intermediate connecting member 6.

[0027] Among them, in order to achieve the assembly of the first rotating portion 1, the second rotating portion 10, and the intermediate connecting member 6 on the same axis, in this embodiment, the first rotating portion 1 has an assembly extension portion 3, and a corresponding assembly hole 11 is opened on the second rotating portion 10 corresponding to the assembly extension portion 3. When the first rotating portion 1 and the second rotating portion 10 are respectively rotatably assembled with the intermediate connecting member 6, the assembly extension portion 3 of the first rotating portion 1 passes through the intermediate connecting member 6 and is rotatably inserted into the assembly hole 11 of the second rotating portion 10. After the assembly of the first rotating portion 1, the second rotating portion 10, and the intermediate connecting member 6 is completed, there is almost no gap inside, and the interior is fully enclosed.

[0028] As Figure 3As shown, a limit bayonet 5 is opened on one side of the cylindrical surface of the assembly extension part 3. A limit retaining piece 12 is arranged in the assembly hole 11 of the second rotating part 10. After the assembly extension part 3 is inserted into the assembly hole 11, the limit retaining piece 12 is snapped into the limit bayonet 5 to prevent the separation of the first rotating part 1 and the second rotating part 10. Since the limit retaining piece 12 is installed in the assembly hole 11, after the limit retaining piece 12 is buckled into the limit bayonet 5, the limit of the first rotating part 1 in the axial direction can be restricted, thus preventing the separation of the first rotating part 1 and the second rotating part 10 in the axial direction. And because the limit retaining piece 12 and the limit bayonet 5 are provided, the first rotating part 1 and the second rotating part 10 can achieve normal circumferential rotation. When the second rotating part 10 rotates to the position of the limit retaining piece 12, the limit retaining piece 12 limits the position, and at this time, the first rotating part 1 cannot continue to rotate relative to the second rotating part 10, as Figure 5 shown. That is to say, the circumferential rotation angle of the first rotating part 1 and the second rotating part 10 depends on the opening of the limit bayonet 5. In this embodiment, the opening angle of the limit bayonet 5 can be 270 degrees. Of course, it can also be smaller or larger, depending on the required rotation angle size.

[0029] The limit retaining piece 12 can be made of elastic metal. During installation, the limit retaining piece 12 can be deformed. After the first rotating part 1 is inserted into the second rotating part 10, the limit retaining piece 12 is used to restore its deformation to achieve the purpose of limiting the position.

[0030] Among them, as Figure 2 shown, the upper and lower ends of the intermediate connecting piece 6 respectively have a protruding positioning and assembling part 7. Positioning and assembling holes 11 are arranged at the positions of the first rotating part 1 and the second rotating part corresponding to the positioning and assembling part 7. When the first rotating part 1 and the second rotating part 10 are respectively installed on both sides of the intermediate connecting piece 6, the first rotating part 1 and the second rotating part 10 are respectively hermetically assembled with the intermediate connecting piece 6. By setting the positioning and assembling part 7 and the positioning and assembling hole 11, after the first rotating part 1, the second rotating part 10, and the intermediate connecting piece 6 are assembled, they have very good positioning and sealing ability, increasing the sealing effect and the rotational stability, as Figure 4 shown. After the first rotating part 1, the second rotating part 10, and the intermediate connecting piece 6 are assembled, there are almost no large gaps, realizing a tight assembly.

[0031] In order to better install the temple component 4 and the temple 8 in the first rotating part 1 and the second rotating part 10, a first mounting hole 2 is installed on the first rotating part 1, and a second mounting hole 9 is installed on the second rotating part 10. One end of the temple component 4 is fixedly assembled into the first mounting hole 2, and one end of the temple 8 is fixedly assembled into the second mounting hole 9. When installing the temple component 4, the temple 8 and the mounting holes of the rotating part, welding fixation can be used after insertion. Of course, side screw locking can also be used, but welding fixation has a longer service life and is more stable in use.

[0032] As Figure 3 shown. One end of the limit stop 12 is fixedly installed on the inner wall surface of the assembly hole 11, and the limit stop 12 is snapped into the limit bayonet 5, and the limit bayonet 5 is formed by circumferentially cutting around the first rotating part 1. In this embodiment, the limit stop 12 and the limit bayonet 5 are used to complete the limit between the first rotating part 1 and the second rotating part 10. Of course, in other embodiments, other rotational limit structures can also be used between the first rotating part 1 and the second rotating part 10 to prevent the separation of the two.

[0033] After the first rotating part 1 is inserted relative to the second rotating part 10, the limit stop 12 is snapped into the limit bayonet 5 and presses down the bottom surface of the limit bayonet 5. In this way, the first rotating part 1 is pressed down relative to the second rotating part 10 by using the limit stop 12, and a tight fit connection can be completed, with better sealing performance.

[0034] The present invention adopts a fully enclosed hinge connector to enhance the connection strength between the temple 8 and the temple component 4 of the glasses. This structure can effectively prevent loosening at the hinge connection. Due to the high sealing performance at the rotating part of the hinge connector, dust and moisture are more difficult to penetrate, ensuring that the hinge part of the spectacle frame has a longer service life;

[0035] In addition, due to the stable connection between the temple 8 and the temple component 4, the shaking of the glasses will be greatly reduced, making the rotation of the hinge structure more stable. This structure not only improves the durability of the glasses, but also enhances the user's comfort and usage experience. The fully enclosed hinge connector significantly improves the quality and structural performance of the glasses.

[0036] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be thought of without creative labor should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
