Description

Technical Field

[0001] The utility model relates to the technical field of learning tools, in particular to a zoom reading and writing table. Background Art

[0002] Reading and writing are scenarios in life where eyes are used more frequently. Usually, people place books directly on the table and read the contents on the screen or book directly with their eyes. However, it is often difficult to maintain an appropriate distance between people and books for a long time in this reading method, especially for children and teenagers with poor self-control. After reading for a long time, they tend to lean their upper body towards the book, or even put their head directly close to the book. Long-term reading and writing in this way can more easily induce myopia. In view of this, a reading table has appeared on the market. Its basic structure consists of a box, a spectrometer placed inside the box, and a concave magnifying glass. The book is placed under the box, and the spectrometer reflects the image of the book into the concave mirror. The concave mirror transmits the image forward through the spectrometer into the human eye. During use, it is necessary to supervise the child to keep his eyes level. This reading table can extend the visual distance and thus prevent myopia.

[0003] However, the viewing distance of traditional reading tables cannot be adjusted and cannot be adjusted according to the needs of different groups of people. Its use is relatively limited. Therefore, our company has specially developed a new type of reading table to overcome the shortcomings of existing technology and meet the further needs of consumers. Utility Model Content

Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The zoom reading and writing table of the preferred embodiment of the utility model is as follows Figure 1-4As shown, the zoom reading and writing table includes a dark box 10, and a projection window 20 and a reading window 30 are respectively provided at the bottom and the front of the dark box 10;

[0032] The zoom reading and writing table further comprises a concave magnifying glass 40 horizontally arranged on the inner top of the dark box 10. The concave magnifying glass 40 is said to be square, but can of course be designed in other shapes such as circular or polygonal;

[0033] The zoom reading and writing table also includes a semi-transparent mirror 50 disposed below the concave magnifying glass 40 to reflect the image forward into the human eye. Generally, the semi-transparent mirror 50 is tilted at an angle of 45 degrees, thereby allowing the image of the concave magnifying glass 40 to be reflected horizontally forward, making it easier for the user to maintain a suitable posture for reading.

[0034] The zoom reading and writing platform also includes an adjustment component 60 for driving the concave magnifying mirror 40 to move up and down. The adjustment component 60 can adopt a linear mechanism such as a screw motor module, a linear motor, an electric cylinder module, or a motor rack module;

[0035] The zoom reading and writing platform also includes a guide rail assembly 70 for guiding the up and down movement of the concave magnifying glass 40. The guide rail assembly 70 can be a slide rail-slider module or a guide shaft-guide sleeve module. Different structural modes can be selected according to actual needs.

[0036] The utility model has a simple overall structure, and the focal length can be adjusted as needed, thereby increasing or decreasing the viewing distance. It can be adjusted according to the needs of different users, is convenient and quick to use, and has high practicality.
