Description

Technical Field

[0001] The invention relates to a study table technology, in particular to a household anti-myopia ergonomic study table. Background Art

[0002] A study table is a new, scientific, humane and practical learning aid suitable for children and teenagers. The tabletop angle of the study table is generally designed to be adjustable, so that users can sit upright and read and write in a comfortable posture. In recent years, with the acceleration of social modernization, the incidence of myopia has continued to increase, and myopia has become one of the most common eye diseases in the world today.

[0003] Myopia is a common problem among primary and secondary school students, which seriously endangers the physical development and health of young children. Recent scientific research results show that the main cause of myopia is due to the adoption of an improper sitting posture. Students often unconsciously move closer to their textbooks when studying, and the vision of adolescents is generally in a plastic stage. Long-term close reading or writing can easily cause myopia. Once students adapt to the myopic sitting posture, it is often difficult for them to change on their own, which in turn affects the vision of young children. Summary of the invention

[0034] Working principle: When using, first, when the user is learning, the handle 31 drives the threaded rod 32 to rotate, and the rotation of the threaded rod 32 drives the sliding rod 43 to move along the guide rod 33, and the movement of the sliding rod 43 drives the abdominal support rod 41 to move and push open the warehouse door 6, so that the abdominal support rod 41 moves to the outside of the storage layer 2, and the handle 31 is stopped after the abdominal support rod 41 reaches the appropriate position, and then the two shoulder support rods 51 are rotated to the appropriate position, and the rotation angle of the two shoulder support rods 51 is adjusted according to the shoulder position of the user. After the adjustment is completed, learning can be carried out. During the learning process of the user, the abdomen and shoulders are affected by the abdominal support rod 41 and the shoulder The abdominal support rod 51 is used to maintain a distance from the study textbook or reading material. When the user involuntarily approaches the reading material, his abdomen or shoulder pushes the abdominal support rod 41 to move to one side. At this time, the support rod 1 on both sides of the abdominal support rod 41 slides along the support rod 2, and the abdominal support rod 41 pushes the T-shaped push rod 422 to move to one side and compresses the spring 2 425. At the same time, the movement of the T-shaped push rod 422 drives the rotating wheel 427 and the limit block 423 thereon to move. When the user pushes the abdominal support rod 41 beyond a certain distance, the protrusion at one end of the limit block 423 is stuck in the limit groove 429, so that the abdominal support rod 41 stops moving to remind the user that he is approaching the reading material.
