读写架制造技术
Reading and writing frame
A reading and writing frame consists of 4 plates and hinges, the plate 1 and the plate 2 are hinges, the plate 2 and the plate 3 are hinges, the plate 3 and the plate 4 are connected by hinges, and the angles formed by the plate 1 and the board 2 are changed when the plate 1 and the plate 4 are fitted and slid each other, and the plate 1 and plate 4 are fixed at a fixed angle when the plate 4 is fixed to each other. It is composed of 4 plates and flexible connecting bands, the plate 1 and the plate 2 are connected with a flexible connecting band, the plate 2 and the plate 3 are connected with a flexible connecting band, the plate 3 and the plate 4 are connected with a flexible connecting band, and the plate 1 and plate 4 are fitted and slid when the plates 1 and 2 are formed by the plate 4, and the plate 1 and plate 4 are fixed when the plate 4 is fixed to each other. Angle. The reading frame is beneficial to the correction of sitting position. When reading and writing, it will not bend forward and bend down. It plays a very good role in preventing myopia and humpback, neck, shoulder and waist pain. At the same time, it also has the advantages of foldable, small size, light weight and easy to carry.
【技术实现步骤摘要】
读写架所属
本专利技术涉及一种读写架，尤其是读写架放在书桌的平面后，形成适合读书和写字角度的读写架。
技术介绍
目前，在学校和办公室，以及家庭中使用的书桌一般都是平面书桌。人们习惯使用平面书桌，但使用平面书桌很难保持正确的坐姿，身体往前弯、驼背、低头读书和写字，这种典型的猿人姿势，会使得肩颈过度紧绷、腰酸背痛、腰椎负担大甚至合并脊椎侧弯或椎间盘突出，甚至许多年轻人颈椎提早退化，长骨刺。当眼睛平视时，颈椎可维持正常应有的弧度，当头部往前倾，颈椎的弧度增加甚至出现明显的转折点，产生颈椎压迫，如果长期低头，颈椎会被拉长、过直，肩颈容易僵硬酸痛，很多学生、上班族长期低头读书和写字，导致颈椎过直。
技术实现思路
为了克服使用平面书桌很难保持正确的坐姿，身体往前弯、驼背、低头读书和写字，长时间采用不正确坐姿，会导致颈、肩、腰部疼痛，容易得近视驼背，对人体健康带来危害的不足，本专利技术提供一种读写架，该读写架放在书桌的平面后，形成适合读书和写字的角度。本专利技术解决其技术问题所采用的技术方案是：读写架由4个板与铰链构成，板1与板2用铰链连接，板2与板3用铰链连接，板3与板4用铰链连接，板1与板4相互贴合和滑动时板1与板2形成的角度得到变化，板1与板4相互固定时板1与板2形成固定的角度。板1与板4通过手拧螺丝进行固定，板2底部有挡板。读写架由4个板与柔性的连接带构成，板1与板2用柔性的连接带连接，板2与板3用柔性的连接带连接，板3与板4用柔性的连接带连接，板1与板4相互贴合和滑动时板1与板2形成的角度得到变化，板1与板4相互固定时板1与板2形成固定的角度。板1与板4通过手拧螺...
