The invention relates to the field of learning machine, in particular to a learning machine mounting frame for preventing myopia, including a placement board and a bottom board. The bottom board is a flat plate. The two sides of the frame are equipped with sliding feet, and the sliding feet are equipped with sliding plates. The sliding plates are equipped with two lifting positioning posts, two lifting positioning posts are equipped with lifting sleeves, and the placement board is installed with lifting boards. On the falling sleeve, the cross-section of the placement plate is C-shaped. The top of the placement plate is provided with a perforation, and the connecting rod is perforated with a connecting rod. One end of the connecting rod is penetrated downwards into the C-shaped placement plate to connect with the top plate, and the other end is penetrated upwards into the C-shaped placement plate to connect with the lifting plate. The connecting rod between the lifting plate and the placement plate is sleeved with a spring, and one end of the spring is connected with the lifting plate. The other end is connected with the placing plate, and a scale is arranged on the bottom plate. The invention is used for installing and placing the learning machine, adjusting the fixed position of the learning machine, so as to avoid the shortsightedness of children caused by the close distance between the holding and placing of the learning machine.
【技术实现步骤摘要】
一种防近视的学习机安装架
本专利技术涉及学习机领域,具体是指一种防近视的学习机安装架。
技术介绍
学习机是在学生群体中比较普及的一种便携式学习设备。早期的学习机和电视机连接,利用电视屏幕进行输出和显示,不具备便携性。后来逐步转向各种尺寸较小、带独立显示屏的电子辞典,提供个人信息管理、游戏、中英词典、中英互译等功能,但所有程序都是固化在存储器上,因而存储能力有限,而且功能不具有扩充性。随着技术的发展,这种便携设备在新的发展中进一步增强了学习功能,支持不同学习形式和多样化科目。功能强大、有些具备开放式操作系统、支持容量扩充、播放器等功能。学习机作为一种高科技学习辅导工具,越来越受到消费者的关注。很多家长都会考虑给孩子选购一台学习机帮助孩子在新学年发挥出更好的成绩,但是目前便携式的学习机虽然方便了携带,但是长时间使用后由于其拿放距离过近及坐姿等原因导致孩子近视,因此,设计一种防近视的学习机安装架对于长时间使用学习机的孩子来说很有现实意义。
