The invention relates to a blackboard, in particular to a novel multifunctional dustproof blackboard. According to the novel multifunctional dustproof blackboard, dust prevention is achieved, chalks are stored, and a foot brake is achieved. A novel multifunctional dustproof blackboard comprises supporting wheels, a supporting plate, a first supporting column, a first pedal, a first spring, a pressing block, a second spring, a first supporting block, a third spring, a blackboard body and the like. A supporting plate is connected among the tops of the four supporting wheels, first supporting columns are arranged on the left side and the right side of the bottom of the supporting plate, and a first pedal is rotationally arranged between the two first supporting columns. Through downward movement of the first supporting frame and the blackboard, when the blackboard is moved to a certain height, people loosen the first pedal, so that the motor is closed, and the adjusting effect is achieved; and a brush is moved downwards, so that a second supporting block moves downwards, a fourth spring is compressed, the cleaning effect is achieved, and the blackboard can be conveniently used next time.
本发明涉及一种黑板,尤其涉及一种新型多功能用防粉尘黑板。本发明提供一种实现防尘,储存粉笔和实现脚刹的新型多功能用防粉尘黑板。一种新型多功能用防粉尘黑板,包括有支撑轮、支撑板、第一支撑柱、第一踏板、第一弹簧、按压块、第二弹簧、第一支撑块、第三弹簧、黑板等;四个支撑轮顶部之间连接有支撑板,支撑板底部左右两侧均设有第一支撑柱,两个第一支撑柱之间转动式设有第一踏板。本发明通过第一支撑架和黑板向下移动,当黑板被移动到一定高度时,人们松开第一踏板,从而使得电机被关闭,达到了调节的效果;通过向下移动毛刷,从而使得第二支撑块向下移动,进而第四弹簧被压缩,达到了清扫的效果,方便了下一次使用黑板。
