Problems solved by technology

[0004] Although some of the existing desks have the ability to adjust the height or change the angle of the desktop, on the one hand, changing the angle of the desktop will affect the learning of students, and on the other hand, changing the angle of the desktop cannot guarantee the anti-myopia of students. Therefore, a desk that can be adjusted according to the actual state of the student's height and has anti-myopia function is needed to meet the needs of students of different heights.

Abstract

The invention discloses a desk capable of preventing myopia. The desk comprises a connecting frame, the connecting frame is movably connected with the table plate through a movable shaft; the connecting frame is connected with the supporting plate through a supporting rod; the table plate is movably connected with the top of the sleeve through a first fixing block. A movable rod is arranged in thesleeve; the bottom of the movable rod is movably connected with a second fixing block; the second fixing block is connected with the supporting plate. The top of the supporting plate is connected with a sliding rod through a first limiting mechanism. A sliding plate is fixedly connected to the end, close to the movable rod, of the sliding rod. The top of the sliding plate is connected with a first screw rod through an adjusting mechanism, the outer surface of the first screw rod is in threaded connection with a threaded sleeve, a second limiting mechanism is connected between the threaded sleeve and the first screw rod, the outer surface of the threaded sleeve is sleeved with a connecting cylinder, and the top of the connecting cylinder is fixedly connected with a limiting plate. The deskhas the advantages that the desk has high strain and diversity, and different requirements of students can be met.

Description

technical field [0001] The invention relates to the technical field of desks, in particular to a desk capable of preventing myopia. Background technique [0002] Myopia in children belongs to myopia, a type of refractive error, which is different from myopia in adults. Myopia (nearsightedness) refers to a refractive state in which parallel rays pass through the refractive system of the eye and fall before the retina when the eye is relaxed. Pediatric myopia refers to the onset of childhood, which is characterized by dysregulation, progression, and multi-factor interference. [0003] In the prior art, the essential cause of myopia in young people is that they look at things near for a long time, the eyes cannot rest for a long time, and visual fatigue occurs for a long time. Myopia, although the existing desks have guardrails to maintain the distance between the desks, but due to the different heights of different students, the guardrails play a limited role in preventing m...
