The utility model discloses a rotary eraser anti dust blackboard blackboard short, including software, which is characterized in that: the blackboard software around the rotating roller of two vertical arranged on the outer wall of the roller; the right end of the sleeve is provided with a rubber sleeve; the right end of the rotating roller bottom type and micro motor the drive shaft is fixedly connected with a bracket; two between two rotating rollers, in front of the vertical bracket fixed on the front wall lining, lining board and soft board before the blackboard and contact in parallel; both ends of the bracket is provided with a sleeve, and soft blackboard two bottom edges are placed on both ends of the sleeve before and after on the outside of the bracket; the two rotating rolls are provided with a dust storage blackboard, blackboard software ends are located in the opposite side of the reservoir between the dust eraser and a rotating roller. The utility model has the advantages of convenient rotation, and the utility model is convenient for students to see the handwriting on the blackboard, and does not affect a large number of writing of the teacher; because the utility model is provided with a dust removing self cleaning blackboard eraser, and no dust flying, the dust pollution can be prevented.
【技术实现步骤摘要】
本技术涉及一种黑板的改进,具体地说是一种旋转自擦防扬尘短黑板。
技术介绍
在学校的教室中,黑板是每个教室中必不可少的教学工具,教室中的黑板大多是固定在墙面上的,且面积比较大,几乎占用整面墙壁,这种黑板的不足之处在于:一是由于黑板太长,不便于学生观看黑板所书写的内容,当老师在中间部分书写的时候,下面的学生能够看清所写内容,但是老师在黑板两边书写的时候,由于黑板面的反光会使教室两边的学生,看不清楚黑板,影响了学生的学习成绩;二是由于黑板擦是用手拿着擦拭黑板,粉尘纷扬下落,影响教室的环境,到处飞扬的粉尘还会被老师和同学吸入,对身体造成危害;三是由于黑板太长,不能只设在教室墙的中间。通过检索,目前尚未见黑板较短、只设在教室墙的中间、又不影响老师大量书写、便于学生全面看清老师书写内容的黑板的报导。
技术实现思路
本技术的目的在于提供一种黑板较短、只设在教室墙的中间,又不影响老师大量书写,便于学生全面看清老师书写内容,且自擦黑板并无粉尘飞扬的旋转自擦防扬尘短黑板。为了达到以上目的,本技术所采用的技术方案是:该旋转自擦防扬尘短黑板,包括软体黑板,其特征在于:所述的软体黑板环绕在两根垂直设置的转动辊上,两根转动辊之间的距离为2-3m;在右端的转动辊的外壁上套设有胶套;所述的右端的转动辊的底部与微型电机的主动轴固定连接;在两个转动辊之间设有两个托架,在托架的前部垂直固定上衬板,衬板的前板面与软体黑板的前壁平行并接触;在托架的两端都设有套筒,软体黑板的前后两个底边沿分别放置在托架的前后两端的套筒上;在两根转动辊的外侧均设有储尘黑板 ...
【技术保护点】
旋转自擦防扬尘短黑板,包括软体黑板(1),其特征在于:所述的软体黑板(1)环绕在两根垂直设置的转动辊(9)上,两根转动辊(9)之间的距离为2?3m;在右端的转动辊(9)的外壁上套设有胶套(5);所述的右端的转动辊(9)的底部与微型电机(6)的主动轴固定连接;在两个转动辊(9)之间设有两个托架(4),在托架(4)的前部垂直固定上衬板(3),衬板(3)的前板面与软体黑板(1)的前壁平行并接触;在托架(4)的两端都设有套筒,软体黑板(1)的前后两个底边沿分别放置在托架(4)的前后两端的套筒上;在两根转动辊(9)的外侧均设有储尘黑板擦(2),软体黑板(1)的两端分别位于相对应一侧的储尘黑板擦(2)和转动辊(9)之间。
