“大簸箕”课桌好用吗?
Is the "big dustpan" desk useful?
小编觉得吧,;大簸箕;课桌不好用,使用起来不方便!尤其是写字时,它阻挡了胳膊的正常摇摆扭转,暂时不太使用,不能普及各大中小学!日前,一种;大簸箕;防近视学习桌,由河南洛阳第42中学教师方春明设计成功,它适用于学生在防近视和休息中使用。其主要由学生旋转学习桌和簸箕式防近视装置构成,通过横垫板和软垫形成的高度,控制眼与书本的距离,从而实现中小学生预防近视的目的,同时学生还可以趴在上面休息。本设计方案利用学生学习时喜欢趴在学习桌上的错误习惯,将错就错设计成可以趴的防近视学习桌。
The editor thinks so,; Big dustpan; The desk is not easy to use and inconvenient to use! Especially when writing, it blocks the normal swinging and twisting of the arms, so it is not widely used and cannot be popularized in all primary and secondary schools! Recently, a type of; Big dustpan; The anti myopia study desk was successfully designed by Fang Chunming, a teacher from Luoyang No. 42 Middle School in Henan Province. It is suitable for students to use in anti myopia and rest. It mainly consists of a rotating learning table for students and a dustpan type anti myopia device. The height formed by horizontal pads and soft pads controls the distance between the eyes and the book, thereby achieving the goal of preventing myopia for primary and secondary school students. At the same time, students can also rest on it. This design scheme takes advantage of the student's habit of leaning on the study desk while studying, and designs a myopia resistant study desk that can be bent down.
事后经过科学分析:学生学习时喜欢趴在学习桌上,是因为学生的腰部肌肉和颈部肌肉力量薄弱,长时间学习造成肌肉疲劳的习惯动作。目前,中小学生防近视用品中,有防近视支架和带防近视支架的文具盒两种多见,它们由于能够控制学生学习时眼与书本的距离,防近视效果较好,但是学生使用常常难以坚持,防近视效果受到很大影响。
After scientific analysis afterwards, it was found that students like to lie on the study desk while studying because their waist and neck muscles are weak, and long-term learning leads to muscle fatigue in their habitual movements. At present, there are two common types of anti myopia products for primary and secondary school students: anti myopia brackets and stationery boxes with anti myopia brackets. They have good anti myopia effects because they can control the distance between students' eyes and books during learning. However, students often find it difficult to persist in using them, and the anti myopia effect is greatly affected.
这样就非常需要一种学生喜欢,能够长期坚持使用,又十分方便的学生用防近视学习桌,本方案由此得出。考虑到学生在学校和家庭中的使用,本方案分别设计了学校型和家庭型两种产品。生产;大簸箕;防近视学习桌,不需要增加设备投资和产品投资,生产一个;大簸箕;防近视学习桌的成本和生产一个普通旋转学习桌的成本差不多。防近视部分生产尺寸:长60厘米x宽45厘米x高20厘米,垫板宽8厘米,下面带撑,另两侧各有一个5厘米半径的半圆孔。;大簸箕;防近视学习桌由于生产成本低和受到学生的喜欢,市场前景将比较好。电动桌厂家生产的电动桌质量好,价格低廉,请广大客户纷纷致电邀约!
