Problems solved by technology

[0002] The movable blackboard for teaching with fast lifting function is a blackboard commonly used in teaching, because it is convenient to move the blackboard, and it is easy to lift, but the existing movable blackboard cannot erase the chalk words written on the blackboard when they move each other, and It is impossible to absorb the pen powder dropped by wiping when the blackboard is moving. Therefore, it is necessary to provide a movable blackboard for teaching with a fast lifting function, which can achieve the effect of enhancing the effect of wiping chalk and absorbing pen powder.

A first blackboard body and a second blackboard body are arranged in the frame, an erasing mechanism is fixed to the side, close to the second blackboard body, of the first blackboard body, a long groove is formed in the top of the frame, a lower groove is formed in the bottom of the frame, an erasing and rolling mechanism is arranged in the long groove, and an absorbing mechanism is arranged at the bottom of the lower groove. The top of the second blackboard is in sliding connection with one side of the long groove, the bottom of the second blackboard is in sliding connection with one side of the lower groove, and the top of the first blackboard is in sliding connection with the top of the long groove.

Description

technical field [0001] The invention is applied to the background of the blackboard technical field, and the name is a movable blackboard for teaching with a fast lifting function. Background technique [0002] The movable blackboard for teaching with fast lifting function is a blackboard commonly used in teaching, because it is convenient to move the blackboard, and it is easy to lift, but the existing movable blackboard cannot erase the chalk words written on the blackboard when they move each other, and It is impossible to absorb the pen powder dropped by wiping when the blackboard is moving. Therefore, it is necessary to provide a movable blackboard for teaching with a fast lifting function, which can enhance the effect of wiping chalk and absorbing pen powder. Contents of the invention [0003] The object of the present invention is to provide a movable blackboard for teaching with fast lifting function, so as to solve the problems raised in the above-mentioned backgr...
