Description

Technical Field

[0001] This utility model relates to the field of eyewear technology, and in particular to an eyeglass frame, eyeglass holder, and eyeglasses that prevent the lenses from being squeezed. Background Technology

[0002] Eyeglasses consist of lenses and frames, with frames made up of eyeglasses frames and temples, and are used to improve vision, such as nearsightedness, farsightedness, astigmatism, presbyopia, strabismus, or amblyopia.

[0003] One type of eyeglass frame is a full-rim plastic frame. When installing the lens on the eyeglass frame, the lens is usually pressed by external force, pressing it into the groove of the eyeglass frame along the inclined guide surface. The lens is clamped by the two side walls of the groove of the eyeglass frame to complete the installation and fixation of the lens.

[0004] However, at this time, the lens is squeezed by the eyeglass frame, which creates a certain internal stress, causing the lens to deform. This leads to the actual correction power of the lens deviating from the preset correction power and changes in other optical properties. Moreover, if worn and used for a long time, it will have an adverse effect on the wearer's vision. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an eyeglass frame, eyeglass holder, and eyeglasses that prevent lens compression, thus preventing lens deformation and ensuring stable lens correction without deviating from the preset correction value.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] This invention provides an eyeglass frame to prevent lens compression, including an elastic groove for fixing the lens; the elastic groove is disposed on the eyeglass frame, and one or both sides of the elastic groove are elastic walls; when the lens is assembled on the eyeglass frame, the outer periphery of the lens is held tightly by the side wall of the elastic groove and stress is generated, while the lens exerts an outward compressive force on the elastic wall, causing the elastic wall to deform; the compressive force corresponds to the deformation of the elastic wall to ensure that the elastic wall elastically clamps the lens, thereby forming an anti-compression device to prevent lens deformation, thus ensuring the stability of the lens's corrective power.

[0008] Furthermore, the inner circumferential surface of the eyeglass frame has two limiting beams that protrude inward and are spaced apart; at least one limiting beam has an elastic clamp for elastically clamping the lens; the limiting beam with the elastic clamp is the elastic wall.

[0009] Furthermore, the limiting beam has a connecting portion, and the inner circumferential surface of the eyeglass frame and the elastic clip are connected through the connecting portion; the connecting portion is provided with a concave groove so that the wall thickness of the connecting portion is less than the wall thickness of the elastic clip, thereby cooperating with the deformation of the elastic clip.

[0010] Furthermore, a flexible decorative element is fitted inside the concave groove.

[0011] Furthermore, the elastic wall includes a plurality of elastic portions spaced apart, which surround the inner circumferential surface of the eyeglass frame.

[0012] Furthermore, the eyeglass frame is a one-piece connected structure.

[0013] Furthermore, the cross-sectional shape of the elastic groove is narrower at the top and wider at the bottom, or U-shaped.

[0014] This utility model also provides an eyeglass frame, including the above-mentioned eyeglass frame for preventing lens compression and temples mounted on both sides of the eyeglass frame.

[0015] This utility model also provides eyeglasses, including the above-mentioned eyeglass frame and a lens mounted on the eyeglass frame, wherein the lens is a corrective lens.

[0016] The technical solution provided by this utility model has the following beneficial effects:

[0017] When the lens is mounted on the eyeglass frame, by setting one or both sides of the elastic groove as elastic walls, the outer periphery of the lens is held tightly by the side walls of the elastic groove, forming stress or pre-tension force to fix the lens. At the same time, the lens applies a certain outward compressive force or reaction force to the elastic wall, so that the elastic wall produces a corresponding deformation, thereby achieving elastic clamping of the lens by the elastic wall, thereby reducing the stress on the lens and preventing the lens from being squeezed and deformed. At the same time, it ensures the stability of the lens's corrective power, that is, it will not deviate from the preset corrective power, and it can also ensure the stability of the lens's optical performance. Moreover, after long-term wear and use, it can also avoid adverse effects on the wearer's vision. Attached Figure Description

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Reference Figures 1 to 3 As shown, Embodiment 1 provides an eyeglass frame to prevent lens compression. The eyeglass frame 1 includes an elastic groove 11 for fixing the lens 5. The elastic groove 11 is disposed on the inner circumferential surface of the eyeglass frame 1. The rear sidewall of the elastic groove 11 is an elastic wall 12. When the lens 5 is assembled on the eyeglass frame 1, the outer periphery of the lens 5 is held tightly by the sidewall of the elastic groove 11 and stress is formed. At the same time, the lens 5 applies an outward compressive force to the elastic wall 12, causing the elastic wall 12 to deform. The compressive force corresponds to the deformation of the elastic wall 12, so as to ensure that the elastic wall 12 elastically clamps the lens 5, thereby forming an anti-compression setting for the lens 5 to prevent deformation of the lens 5, thereby ensuring the stability of the corrective power of the lens 5.

[0027] In this embodiment, two lenses 5 are mounted on the eyeglass frame 1 located on the left and right sides, and the sidewalls or groove walls of the elastic groove 11 are arranged in front and back.

[0028] When the lens 5 is installed on the eyeglass frame 1, by setting the sidewall of the elastic groove 11 as an elastic wall 12, the outer periphery of the lens 5 is held tightly by the sidewall of the elastic groove 11 and stress or pre-tightening force is formed to fix the lens 5. At the same time, the lens 5 applies a certain outward compressive force or reaction force to the elastic wall 12, so that the elastic wall 12 produces a corresponding deformation, so as to achieve elastic clamping of the lens 5 by the elastic wall 12, thereby reducing the stress on the lens 5 and preventing the lens 5 from being squeezed and deformed. At the same time, it ensures the stability of the corrective power of the lens 5, that is, it will not deviate from the preset corrective power, and it can also ensure the stability of the optical performance of the lens 5. After long-term wear and use, it can also avoid adverse effects on the wearer's vision.

[0029] Of course, in other embodiments, the front sidewall of the elastic groove 11 can also be an elastic wall 12, or both the front and rear sidewalls of the elastic groove 11 can be elastic walls 12, thus preventing the lens 5 from being squeezed.

[0030] In another preferred embodiment, the inner peripheral surface of the eyeglass frame 1 has two limiting beams that protrude inward and are spaced apart. One of the limiting beams located at the rear has an elastic clamping portion 122 for elastically clamping the lens 5. The limiting beam with the elastic clamping portion 122 is the elastic wall 12. At this time, the elastic clamping portion 122 extends toward the lens 5 inside the eyeglass frame 1 and can abut against the outer periphery of the lens 5.

[0031] More specifically, the limiting beam has a connecting part, and the inner circumferential surface of the eyeglass frame 1 and the elastic clip 122 are connected through the connecting part. The connecting part is provided with a concave groove 121 so that the wall thickness of the connecting part is less than the wall thickness of the elastic clip 122, thereby cooperating with the deformation of the elastic clip 122, that is, the elastic clip 122 bends around the connecting part.

[0032] In this specific embodiment, such as Figure 1 The cross-sectional shape of the elastic groove 11 shown is narrow at the top and wide at the bottom. The two limiting beams are set at an angle and the eyeglass frame 1 is an integral connection structure. This allows the two limiting beams and the inner circumferential surface of the eyeglass frame 1 to form the elastic groove 11 through an integral connection, so as to ensure the overall structural strength of the eyeglass frame 1 as well as its lightweight and durability.

[0033] The elastic clip 122 is located on the side of the concave groove 121 away from the inner circumferential surface of the eyeglass frame 1, and the two groove walls of the concave groove 121 are arranged in an inner and outer ring.

[0034] The concave groove 121, in conjunction with the elastic clamp 122, allows the elastic clamp 122 to move closer to or further away from the concave groove 121 and closer to the inner circumferential surface of the eyeglass frame 1, thereby achieving elastic clamping of the lens 5.

[0035] When the lens 5 is about to be pressed into the elastic groove 11, the elastic clamp 122 is forced to bend outward and approach the outer ring side wall 1211 of the concave groove 121 under the force of the external force overcoming the elastic force of the elastic clamp 122, so that the opening distance of the two limiting beams is sufficient to realize that the lens 5 is inserted into the elastic groove 11. At this time, the outer ring side wall 1211 is the side wall of the concave groove 121 near the inner circumferential surface of the eyeglass frame 1.

[0036] like Figure 3As shown, after the lens 5 is assembled in the elastic groove 11, the external force is removed, and the elastic clamp 122 rebounds under its own elastic force. The elastic clamp 122 bends inward and moves away from the outer ring sidewall 1211, so that the opening distance of the two limiting beams is reduced, so that the elastic clamp 122 elastically abuts against the outer periphery of the lens 5, so that the elastic clamp 122 of the elastic wall 12 elastically clamps the lens 5, thereby reducing the stress on the lens 5, preventing the lens 5 from being squeezed and deformed, so as to ensure that the correction power of the lens 5 is stable, that is, it will not deviate from the preset correction power.

[0037] Of course, in other embodiments, the cross-sectional shape of the elastic groove 11 is U-shaped.

[0038] Further preferred, such as Figure 2 The elastic wall 12 shown includes five elastic portions 123 spaced apart, which surround the inner circumferential surface of the eyeglass frame 1.

[0039] In this specific embodiment, each of the five elastic parts 123 has its own elastic clamping part 122. The elastic clamping parts 122 of two adjacent elastic parts 123 are disconnected from each other to ensure that the deformation of each elastic part 123 does not affect each other. The bending amount or deformation of the corresponding elastic clamping part 122 can be adjusted according to the various local external dimensions of the lens 5 to reduce the stress in various local areas of the lens 5 and distribute it evenly, so as to further ensure the stability of the correction power of the lens 5.

[0040] Of course, in other embodiments, the number of elastic parts 123 may be two, three, four or six or more. The specific number of elastic parts 123 is determined according to the shape and structure of the eyeglass frame 1 and the lens 5, so as to ensure that the stress received by the lens is small enough and evenly distributed.

[0041] In another preferred embodiment, a flexible decorative element is fitted inside the concave groove 121 to enhance the aesthetics and prevent dust and dirt from entering the concave groove 121, making it convenient for the wearer to clean.

[0042] Example 2

[0043] Reference Figure 4 and Figure 5 As shown, Embodiment 2 provides an eyeglass frame, including the eyeglass frame 1 of Embodiment 1 that prevents the lenses from being squeezed and the temples 2 assembled on both sides of the eyeglass frame 1.

[0044] In this embodiment, the two eyeglass frames 1 located on the left and right sides are fixed together by the nose bridge 3, and each eyeglass frame 1 is equipped with a nose pad 4.

[0045] When the lens is installed on the eyeglass frame 1 of the eyeglass frame in this embodiment, by setting the sidewall of the elastic groove as an elastic wall, the outer periphery of the lens is held tightly by the sidewall of the elastic groove and stress or pre-tightening force is formed to fix the lens. At the same time, the lens applies a certain outward compressive force or reaction force to the elastic wall, so that the elastic wall produces a corresponding deformation, so as to realize the elastic clamping of the lens by the elastic wall, thereby reducing the stress on the lens and preventing the lens from being squeezed and deformed, so as to ensure the stability of the lens correction power, that is, it will not deviate from the preset correction power, and after long-term wear and use, it can also avoid adverse effects on the wearer's vision.

[0046] Example 3

[0047] Embodiment 3 provides a pair of glasses, including the eyeglass frame of Embodiment 2 and lenses mounted on the eyeglass frame. The lenses are corrective lenses. By setting anti-compression measures for the lenses, the corrective power of the lenses is ensured to be stable, that is, it will not deviate from the preset corrective power. Moreover, after wearing and using the glasses of this embodiment for a long time, it can also avoid adverse effects on the wearer's vision.

[0048] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
