Description

机擦吸尘可调式黑板擦
技术领域
本实用新型涉及一种黑板擦的改进,具体地说是一种机擦吸尘可调式黑板擦。
目前,机关、学校等单位使用的黑板擦,一般都是用毛毡粘贴在木板上,教师手持木板在黑板上用力擦去粉笔痕迹,上述黑板擦,因简单现虽普遍应用,但也存有以下不足:一是教师用力擦黑板,劳动强度大,费时费力;二是擦下的粉笔沫,污染环境,危害教师和学生的身体健康;三是毡擦不能调整,毛毡用完后,剩下木板就得更换新擦,造成很大浪费。
发明内容
本实用新型的目的在于提供一种使用方便,减轻劳动强度,省时省力,避免环境污染,有利教师和学生身体健康,毡擦可调,减少浪费的机擦吸尘可调式黑板擦。
为达到以上目的,本实用新型所采取的技术方案是:该机擦吸尘可调式黑板擦,由壳体、壳体盖、毡擦构成,其特征在于在壳体内设微型电机,外设电池盒,电池盒内设电池,外设电池开关,微型电机轴连接吸尘扇后与调节装置的调节螺母相接,在毡擦内并设有吸尘孔。本实用新型还通过如下措施实施:所述的调节装置,由调节螺母、调节螺杆、固定螺母构成,调节螺杆一端与调节螺母连接,另一端用固定螺母将毡擦固牢。使用本实用新型时,操作者右手握住壳体,打开电池开关,微型电机带动吸尘扇和毡擦旋转,将旋转的毡擦贴在黑板上,将粉笔痕迹擦去,擦下的粉笔沫,被旋转的吸尘扇通过吸尘孔吸入壳体盖中,在排除粉笔沫时,关闭电池开关,拧开壳体盖倒出;当毡擦磨损至壳体下沿时,左旋调节螺杆,使毡擦露出壳体下沿继续使用,在毡擦不能使用时可更换。
本实用新型的有益效果在于:与目前的黑板擦相比,具有使用方便,减轻劳动强度,省时省力,避免环境污染,有利教师和学生身体健康,毡擦可调,减少浪费的优点。
附图说明
图1为本实用新型结构主视局剖示意图。
具体实施方式
