The utility model relates to the field of teaching appliances, in particular to a hanging chart support for students, which comprises a disc base, a telescopic support rod, a telescopic column and a T-shaped plate. The back of the T-shaped plate is provided with three suckers with triangular distribution, the lower end of the T-shaped plate is fixed with a threaded connecting cylinder, and the threaded connecting cylinder is screwed with a telescopic column, and the telescopic column is screwed on the disc base. A universal wheel is arranged at the lower four corners of the base, and four telescopic supports are symmetrically fixed on both sides of the T-shaped plate. The structure design of the utility model is reasonable. The wall map height of the support can be adjusted by adjusting the expansion column, and the wall map of different sizes can be stretched by adjusting the expansion support, so as to prevent the curl of the wall map from affecting the teaching effect. The wall map support can be moved flexibly by universal wheel, and the expansion column can be removed. Then the wall map support can be directly absorbed and fixed on the blackboard or wall surface by suction cup. Easy to use, easy to fold and store.

一种学生用随堂挂图支架
本技术涉及教学用具领域,尤其是一种学生用随堂挂图支架。
技术介绍
目前,在课堂教学中经常需要使用图纸、图画等挂图资料来辅助进行互动教学,以便于学生更加直观的学习理解,现有的挂图方式一般是直接挂在黑板上或者使用胶纸粘贴在黑板上,使用非常不便,且一些挂图储存时通常是卷起或折叠存放,因而一些挂图悬挂使用时不能平顺的舒展开,其页面上会存在卷曲或褶皱,给挂图使用带来不便,影响教学效果。
技术实现思路
本技术的目的是为了克服上述技术缺点提供一种学生用随堂挂图支架。通过调节伸缩立柱可以调整支架挂图高度,通过调节伸缩支杆可以舒展的悬挂不同大小的挂图,防止挂图卷曲影响教学效果。本技术解决技术问题采用的技术方案为:一种学生用随堂挂图支架,包括圆盘底座、伸缩支杆、伸缩立柱、T形板,所述T形板背面设有呈三角形分布的3个吸盘,T形板下端固定设有螺纹连接筒,螺纹连接筒内螺接固定有伸缩立柱,伸缩立柱螺接固定在圆盘底座上,圆盘底座下侧四角部位设有万向轮,所述伸缩支杆两端均设有椭圆形的连接片,伸缩支杆顶端的连接片上铰接固定有固定夹,伸缩支杆尾端的连接片通过梅花手柄螺丝螺接固定在 ...
