Description

Technical Field

[0001] The utility model relates to the field of optical glasses, in particular to an optical glass with a sunshade function. Background Art

[0002] Optical glasses are a device used to correct vision, eliminate visual fatigue, protect or treat eyes. They usually include frames on the left and right sides, lenses are arranged in the frames, a center bridge is arranged between the frames on both sides, each frame is provided with a nose pad under the center bridge, and the frame is hinged with temples on the other side of the other frame.

[0003] Common optical glasses do not have sunshade function. When the sun is particularly strong, they cannot block the sun from shining on the eyes, which not only affects the vision, but also affects the eye recovery after surgery. If you wear sunglasses with correction function, the wearer's field of vision will become darker, making it difficult to observe things and reducing the sensitivity when encountering emergencies. In addition, the high price also increases the consumer burden. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an optical pair of glasses with a sunshade function which can freely switch between a sunshade state and a non-sunshade state.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including frames respectively located on the left and right sides, lenses are arranged in the frames, a middle beam is arranged between the frames on the two sides, each frame is provided with a nose pad under the middle beam, and the frames are hingedly provided with temples on the other side of the other frame, and also include two sunshade seats respectively located above each frame, the upper end surface of the middle beam and the upper end surface of the frame form a mounting platform, the mounting platform is provided with a dovetail slide rail along the left and right directions, the sunshade seat is provided with a dovetail groove that slidably cooperates with the dovetail slide rail and slides into the dovetail slide rail from the adjacent end, and deformable sunshades are respectively provided in front and at the rear of the sunshade seat.

[0006] By adopting the above technical solution, when the optical glasses need to be shaded, the sunshade seat is pushed in from the end of the dovetail slide rail, and the sunshade will form a sunshade barrier in front of the eyes after it is in place, that is, the optical glasses are in a sunshade state; when the optical glasses are not needed for sunshade, the sunshade seat can be pulled out from the dovetail slide rail, that is, the optical glasses are in a non-sunshade state. The above structure has the following advantages: ① The sunshade seat can be used as a freely assembled module, and is only assembled when needed (single / two), which reduces the burden of wearing when no sunshade is required, and the plug-in installation method is also relatively simple; ② When the optical glasses are in a sunshade state, the field of vision can be kept bright, ensuring the wearer's ability to observe things normally and the sensitivity to respond to emergencies, and because it is close to the eyes, its sunshade effect is better than wearing a hat; ③ The sunshade has two parts, front and back, which not only forms a sunshade barrier on the front of the glasses, but also prevents light from entering the eyes from the gap between the face and the glasses, and has a comprehensive sunshade effect; ④ The sunshade has a deformation function and can be adjusted according to the facial contour or the angle of the skylight to ensure the sunshade effect.

[0007] The utility model is further configured as follows: the sunshade comprises a flexible fabric and a deformable metal strip surrounding the flexible fabric.

[0008] By adopting the above technical solution, the wearer can clamp the left and right ends of the sun visor with the thumb and index finger respectively, and can quickly adjust the shape of the sun visor (height, curvature, front and back position) by bending the metal strip. The sun visor can also stably maintain the adjusted shape, making the adjustment easier and more in line with actual needs, thereby optimizing the sunshade effect.

[0009] The utility model is further configured as follows: a limiting block is arranged above the installation platform in the middle of the dovetail slide rail, the left and right side surfaces of the limiting block serve as limiting surfaces respectively, the sunshade seat is opposite to the position of the mirror frame when it is against the limiting surface, each limiting surface is arranged above the dovetail slide rail with a first magnetic strip, and each sunshade seat is arranged towards the limiting surface with a second magnetic strip that is attracted to the first magnetic strip.

[0010] By adopting the above technical solution, a single limit block can realize the limit structure of the sunshade seats on both sides, making the structure more streamlined. After the sunshade seats are inserted into place, the suction force formed by the first magnetic strip and the second magnetic strip effectively prevents the sunshade seats from shifting due to external vibrations, thereby stably maintaining the sunshade effect.

[0011] The utility model is further configured as follows: the left and right sides of the sunshade cover are respectively provided with extension parts extending to the outside of the sunshade seat.

[0012] By adopting the above technical solution, the shading area of ​​the sunshade is increased by extending the part, which not only covers the sides of the glasses but also covers the top of the middle beam, making the shading effect more comprehensive.

[0013] The utility model is further configured as follows: friction lines are respectively arranged on the front and rear sides of the sunshade seat away from the limiting block.

[0014] By adopting the above technical solution, when the sunshade seat needs to be pulled out, the thumb and index finger need to clamp the front and rear sides of the sunshade seat away from the limit block. The friction lines increase the friction between the sunshade seat and the fingers, making the pulling out more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] like Figure 1 — Figure 4As shown, the utility model discloses an optical spectacles with sunshade function, including frames 1 respectively located on the left and right sides, lenses 2 are arranged in the frames 1, a middle beam 3 is arranged between the frames 1 on both sides, each frame 1 is provided with a nose pad 4 located below the middle beam 3, and the other side of the frame 1 relative to the other frame 1 is hingedly provided with temples 5, and also includes two sunshade seats 7 respectively located above each frame 1, the upper end surface of the middle beam 3 and the upper end surface of the frame 1 form a mounting platform 6, the mounting platform 6 is provided with a dovetail slide rail 61 along the left and right directions, the sunshade seat 7 is provided with a dovetail groove 71 that is slidably matched with the dovetail slide rail 61 and slides into the dovetail slide rail 61 from the adjacent end, and a deformable sunshade 72 (including Figure 4 a represents the front part and Figure 4 b) represents the rear part. When the optical glasses need sun protection, the sunshade seat 7 is pushed in from the end of the dovetail slide rail 61. After it is in place, the sunshade cover 72 will form a sunshade barrier in front of the eyes, that is, the optical glasses are in a sun-shielding state; when the optical glasses are not needed for sun protection, the sunshade seat 7 can be pulled out from the dovetail slide rail 61, that is, the optical glasses are in a non-sun-shielding state. The above structure has the following advantages: ① The sunshade seat 7 can be used as a freely assembled module, and it is only assembled when needed (single / two), which reduces the burden of wearing when no sun protection is needed, and the plug-in installation method is also convenient. The invention is relatively simple; ② when the optical glasses are in the sun-shading state, the field of vision can be kept bright, thus ensuring the wearer's ability to observe things normally and the sensitivity to deal with emergencies, and because the distance between the glasses and the eyes is closer, the sun-shading effect is better than wearing a hat; ③ the sunshade 72 has two parts, the front and the back, which not only forms a sunshade barrier on the front of the glasses, but also prevents light from entering the eyes from the gap between the face and the glasses, thus having a comprehensive sun-shading effect; ④ the sunshade 72 has a deformation function, which can be adjusted according to the facial contour or the angle of the skylight to ensure the sun-shading effect.

[0022] The sunshade 72 includes a flexible fabric 721 and a deformable metal strip 722 surrounding the flexible fabric 721. The flexible fabric 721 can be made of common plastic, cloth, etc., and the metal strip 722 can be made of iron, aluminum, etc. The wearer holds the left and right ends of the sunshade 72 with the thumb and index finger of both hands respectively, and the shape (height, curvature, front and back position) of the sunshade 72 can be quickly adjusted by bending the metal strip 722. The sunshade 72 can also stably maintain the adjusted shape, making the adjustment easier and more in line with actual needs, thereby optimizing the sunshade effect.

[0023] A limiting block 62 is arranged above the mounting platform 6 in the middle of the dovetail slide rail 61, and the left and right side surfaces of the limiting block 62 serve as limiting surfaces 621 respectively. When the sunshade seat 7 is in contact with the limiting surfaces 621, it is opposite to the position of the mirror frame 1. Each limiting surface 621 is arranged above the dovetail slide rail 61 and a first magnetic strip 622 is arranged thereon. Each sunshade seat 7 is arranged facing the limiting surface 621 and is provided with a second magnetic strip 73 which is attracted to the first magnetic strip 622. A single limiting block 62 can realize the limiting structure of the sunshade seats 7 on both sides, making the structure more streamlined. After the sunshade seat 7 is inserted into place, the attraction force formed by the first magnetic strip 622 and the second magnetic strip 73 can effectively prevent the sunshade seat 7 from shifting due to external vibration, thereby stably maintaining the sunshade effect.

[0024] The left and right sides of the sunshade 72 are respectively provided with extension parts 723 extending to the outside of the sunshade seat 7. The extension parts 723 increase the shading area of ​​the sunshade 72, not only covering the sides of the glasses, but also covering the top of the middle beam 3, so that the shading effect is more comprehensive.

[0025] The front and rear sides of the sunshade seat 7 away from the limit block 62 are respectively provided with friction lines 74, which are composed of multiple parallel raised lines in the accompanying drawing. When the sunshade seat 7 needs to be pulled out, the thumb and index finger need to clamp the front and rear sides of the sunshade seat 7 away from the limit block 62. The friction lines 74 increase the friction between the sunshade seat 7 and the fingers, making the pulling out more labor-saving.
