Description

Technical Field

[0001] The present application relates to the technical field of reading glasses, and in particular to a reading glass with adjustable pupil distance of lenses. Background Art

[0002] A reading glass is a pair of glasses designed specifically for people with presbyopia to help middle-aged and elderly people see nearby objects more clearly. The pupil distance of the glasses is an important indicator of whether the glasses are comfortable to wear. If there is an error between the pupil distance of the glasses and the pupil distance of the human eye, wearing them will be very uncomfortable.

[0003] In the related art, a reading glass includes a frame and two lenses, and both lenses are fixedly connected to the frame.

[0004] Unlike myopia glasses, generally speaking, reading glasses are not customized, so reading glasses are usually standardized, and the pupil distances of the lenses in the reading glasses are the same, making the pupil distances of the lenses unable to adapt to the pupil distances of the human eyes. As a result, people will feel uncomfortable when wearing reading glasses with mismatched pupil distances. Utility Model Content

[0005] In order to improve the problem that the pupil distance of the lens in the reading glass is different from the pupil distance of the human eye, the present application provides a reading glass with adjustable pupil distance of the lens.

[0006] A reading glass with adjustable pupil distance of the lens provided by the present application adopts the following technical solutions:

[0007] A reading glass with adjustable pupil distance of the lens includes a frame and two lenses. An installation groove for installing the lens is provided on the frame. An adjusting wheel is rotatably connected to the frame. An adjusting structure is provided on the lens. The adjusting wheel drives the lens to face or move away from the other lens in the installation groove through the adjusting structure.

[0008] By adopting the above technical solutions, the adjusting structure is driven to move by the adjusting wheel, and the adjusting structure drives the lens, so as to realize the movement of the lens in the installation groove, thereby changing the pupil distance of the lens, enabling the pupil distance of the lens to adapt to the pupil distance of the human eye, so that people can adjust it by themselves when purchasing reading glasses, making people more comfortable when wearing reading glasses; at the same time, making the reading glasses adaptable to more people and increasing the applicability of the reading glasses.

[0009] Optionally, the adjusting structure includes a first fixing strip and a second fixing strip. The first fixing strip is rotatably connected to the side of the adjusting wheel. The second fixing strip is rotatably connected to the first fixing strip. The second fixing strip is arranged on the lens. When the adjusting wheel rotates, the adjusting wheel drives the first fixing strip and the second fixing strip to move.

[0010] By adopting the above technical solution, when the adjusting wheel rotates, the adjusting wheel can drive the first fixing strip to move. The first fixing strip drives the lens to move horizontally through the second fixing strip, so that the lens moves towards or away from the direction of another lens, enabling the two lenses to move synchronously and allowing the interpupillary distance of the lens to be adjusted to adapt to the interpupillary distances of the eyes of different people.

[0011] Optionally, a rotating cavity is formed in the frame, the adjusting wheel is rotatably connected in the rotating cavity, and a sliding groove communicating with the rotating cavity is formed in the frame. People rotate the adjusting wheel through the sliding groove.

[0012] By adopting the above technical solution, the rotating cavity is communicated with the sliding groove, and people can rotate the adjusting wheel through the sliding groove, which facilitates the rotation of the adjusting wheel and makes it more convenient to rotate the adjusting wheel.

[0013] Optionally, a retaining rib is provided on the adjusting wheel, and the retaining rib can abut against the inner wall of the rotating cavity.

[0014] By adopting the above technical solution, the retaining rib can abut against the inner wall of the rotating cavity, making the adjusting wheel more stable in the rotating cavity and reducing the situation that the adjusting wheel rotates randomly in the rotating cavity. After people adjust the interpupillary distance of the lens, the interpupillary distance of the lens is not likely to change.

[0015] Optionally, one of the first fixing strips is located on one side surface of the adjusting wheel, and the other first fixing strip is located on the other side surface of the adjusting wheel.

[0016] By adopting the above technical solution, since one of the first fixing strips is located on one side surface of the adjusting wheel and the other first fixing strip is located on the other side surface of the adjusting wheel, and the two first fixing strips are respectively located on both sides of the adjusting wheel, when the adjusting wheel rotates, the two first fixing strips and the two second fixing strips will not interfere with each other, enabling the adjusting wheel to stably drive the adjusting structure to rotate. If one of the first fixing strips is damaged and cannot move, it will not affect the movement of the other first fixing strip.

[0017] Optionally, a fixing groove communicating with the installation groove is formed in the frame, the second fixing strip is slidably connected in the fixing groove, and an anti-slip rib is provided on the second fixing strip, and the anti-slip rib can abut against the groove wall of the fixing groove.

[0018] By adopting the above technical solution, the anti-slip rib can abut against the groove wall of the fixing groove, so that the anti-slip rib can limit the movement of the second fixing strip in the fixing groove, thereby making it difficult for the second fixing strip to move in the fixing groove, further enhancing the stability of the lens in the installation groove and making it difficult for the interpupillary distance of the lens to change.

[0019] Optionally, the adjusting structure includes a rack which is disposed on the lens. The adjusting wheel and the rack are meshed with each other. A receiving cavity is formed on the spectacle frame. The adjusting wheel is rotatably connected in the receiving cavity. A through hole communicating with the receiving cavity is formed on the spectacle frame, and the through hole is for people to rotate the adjusting wheel.

[0020] By adopting the above technical solution, people rotate the adjusting wheel through the through hole. Since the adjusting wheel and the rack are meshed with each other, the adjusting wheel can drive the rack to move, so that the lens moves towards or away from the direction of the other lens, changing the pupillary distance of the lens, so as to adapt the pupillary distance of the lens in the presbyopic glasses to the pupillary distance of people's eyes.

[0021] Optionally, a cross hole is formed on the adjusting wheel, and the cross hole is aligned with the through hole.

[0022] By adopting the above technical solution, by aligning the cross hole with the through hole, people can directly rotate the adjusting wheel through a tool, so as to facilitate the rotation of the adjusting wheel. At the same time, if the tool is missing, it is difficult for the adjusting wheel to rotate, reducing the possibility that people accidentally touch and rotate the adjusting wheel.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The adjusting wheel drives the adjusting structure to move, and the adjusting structure drives the lens, realizing the movement of the lens in the installation groove, so that the pupillary distance of the lens changes, enabling the pupillary distance of the lens to adapt to the pupillary distance of the human eye, so that people can adjust by themselves when purchasing presbyopic glasses, making people more comfortable when wearing presbyopic glasses. At the same time, the presbyopic glasses can be adapted to more people, increasing the applicability of the presbyopic glasses.

[0025] 2. By connecting the sliding groove with the rotating cavity, people can rotate the adjusting wheel through the sliding groove, facilitating the rotation of the adjusting wheel by people and making the rotation of the adjusting wheel more convenient.

[0026] 3. People rotate the adjusting wheel through the through hole. Since the adjusting wheel and the rack are meshed with each other, the adjusting wheel can drive the rack to move, so that the lens moves towards or away from the direction of the other lens, changing the pupillary distance of the lens, so as to adapt the pupillary distance of the lens in the presbyopic glasses to the pupillary distance of people's eyes.
