Description

Technical Field

[0001] The utility model relates to the technical field of learning tools, in particular to a reader light shield and a reader using the light shield. Background Art

[0002] In recent years, the number of myopic people in my country has increased, especially among teenagers. In addition, the number of spinal and cervical diseases caused by long hours of reading with the head lowered has also increased. The current methods of preventing myopia are to use mechanical structure design or electronic equipment to force or remind readers to straighten their body posture, keep the eyes as far away from the book as possible, and read at the correct viewing angle, so as to prevent myopia and spinal and cervical diseases.

[0003] In order to solve this problem, there are readers on the market that can provide children with a correct reading angle and sitting posture, such as the solution disclosed in the patent with patent number CN216202723U, which has an eyepiece and an objective lens arranged in front and back, a flip arm that rotates to connect the eyepiece and the objective lens, and a support frame mechanism for adjusting the position of the eyepiece and the objective lens. When in use, the eyepiece and the objective lens are adjusted to the front of the user's face through the support frame mechanism, so that the user can maintain an adaptive angle of view, such as looking straight ahead. The image of the book or electronic device on the desktop is reflected into the user's eyes through the cooperation of the objective lens and the eyepiece, so that the user can maintain a good learning posture for reading and learning.

[0004] In addition, there are also upgraded products based on the above-mentioned products on the market, such as the solution disclosed in the patent with patent number CN219552771U, which not only has the above-mentioned functions, but also has the function of preventing attention distraction. The principle is to set shading plates on both sides of the eyepiece and the objective lens. However, the core component of the upgraded product, the shading plate, adopts an integrated design, which makes it impossible to take into account both the new and old products. When the product purchased by the user only has the function disclosed in patent number CN216202723U, if you want to upgrade to the function of preventing attention distraction, you can only buy a new upgraded product, and repurchasing will cause the original product to be abandoned, resulting in unnecessary waste. Therefore, it is necessary to design a shading hood that can be used for old products to meet user needs. Utility Model Content

For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0026] Moreover, the terms "up, down, left, right, upper end, lower end, longitudinal" and the like indicating directions are all based on the posture and position of the device or equipment described in this solution during normal use.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0028] The reader light shield of the preferred embodiment of the utility model is as follows Figure 1-4 As shown, the visor includes a fixed plate 10, and two visors 20 respectively arranged at the left and right ends of the fixed plate 10. The fixed plate 10 can be removably arranged on the eyepiece 100, and the connection between the two can be achieved by Velcro, buckle, magnetic attraction or clamping and snap connection. The two visors 20 are arranged longitudinally and the eyepiece 100 is located between the two visors 20. When assembled in place, the fixed plate 10 and the two visors 20 enclose a chamber 30 to prevent distraction, so that when the user uses it, the light from the surrounding environment entering the eyepiece 100 and the objective lens 200 can be reduced, avoiding the user's attention from being diverted, thereby achieving the purpose of preventing distraction.

[0029] The overall structure of this solution is simple, and the fixing plate 10 can be removably set on the eyepiece 100, which is easy to use. The user can remove and install the fixing plate 10 at any time when the user needs to use the light shield, which greatly meets the needs of the user and reduces the waste of resources and user funds. The up and down position adjustment of the objective lens 200 will not be affected during use.

[0030] In this embodiment, the fixing plate 10 includes a first plate 101, which can be removably opened on the back of the eyepiece 100, and the fixing plate 10 also includes a second plate 102 arranged on the back of the first plate 101, and the second plate 102 is slidably fitted with the first plate 101, and the two light shielding plates 20 are respectively vertically arranged on the two opposite ends of the first plate 101 and the second plate 102. The left-right sliding arrangement of the first plate 101 and the second plate 102 can facilitate the adaptation to eyepieces 100 of different lengths, further increasing the adaptability of the light shielding cover.

[0031] In this embodiment, the light shield also includes an adjustment mechanism 103 for adjusting the left and right relative positions of the first plate 101 and the second plate 102, so as to adjust and fix the position of the second plate 102. At the same time, it can also increase the friction force after the two light shielding plates 20 are attached to the left and right end surfaces of the eyepiece 100, and further play the role of fixing the light shield. Among them, the adjustment mechanism 103 includes a first fixing seat 1031 arranged on the first plate 101, a second fixing seat 1032 arranged on the second plate 102, and a connecting rod 1033 arranged horizontally. One end of the connecting rod 1033 is longitudinally rotatably connected to the first fixing seat 1031, and the other end is threadedly connected to the second fixing seat 1032. When the position of the second plate 102 needs to be adjusted, the connecting rod 1033 is rotated to make the thread push the second fixing seat 1032, thereby realizing the rapid adjustment of the position of the second plate 102, which is convenient and fast, and the structure is simple and practical.

[0032] In this embodiment, the first plate body 101 is also provided with a guide column 40 for guiding the lateral movement of the second plate body 102, and the second plate body 102 is provided with a guide sleeve 50 slidably mounted on the guide column 40 to ensure that the second plate body 102 can maintain good stability and smoothness during the left and right movement to avoid large shaking.

[0033] In this embodiment, the guide column 40 and the guide sleeve 50 form a unit. Two guide columns 40 and the guide sleeve 50 are arranged side by side in the longitudinal direction to further improve the stability of the movement of the second plate 102 .

[0034] In this embodiment, the lower end of the fixing plate 10 is attached to the back of the eyepiece 100, and the upper end of the fixing plate 10 extends forwardly at an angle. The front end of the light shielding plate 20 is provided with an extension portion 201 extending forward. When in use, the front end of the extension portion abuts against the upper end of the objective lens 200, thereby playing a supporting and stabilizing role.

[0035] In this embodiment, the left and right ends of the fixing plate 10 are aligned with the left and right ends of the eyepiece 100 to ensure the compactness of the structure.

[0036] In the present embodiment, a support platform 60 adapted to the top surface of the eyepiece 100 is convexly provided on the front side wall of the fixing plate 10. When assembled in place, the support platform 60 abuts against the top of the eyepiece 100 to prevent the fixing plate 10 from sliding down, thereby fixing the fixing plate 10. In order to further ensure stability, the support platform 60 is in the shape of an elongated strip and is arranged horizontally and fits with the upper end of the eyepiece.
