Problems solved by technology

[0003] The disadvantages of existing blackboards are: when using a dry-type eraser to remove handwriting, there is a lot of dust in the room, which is not conducive to air cleaning, the physical and mental health of teaching staff and the maintenance of indoor instruments; After drying, it can be used again
The partial position of the corners of the blackboard still cannot be cleaned in time, which affects the normal teaching
At the same time, the system is noisy, unstable and difficult to maintain, so the water-washed blackboard has appeared for a long time but has not been popularized.

Embodiment Construction

[0044] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail

[0045] This embodiment includes the following mechanisms: (1) board updating mechanism; (2) clutch mechanism; (3) cleaning mechanism and its water circulation mechanism at the back of the blackboard; (4) overall displacement mechanism and safety mechanism of the blackboard.

[0046] 1. Board update mechanism

[0047] Structural description: To renew the board surface, first move the frame (108), separate the slats (101) and the static frame (107) to form a suitable distance between each other (to avoid flipping interference), then flip 180° successively, and then press together to achieve . like figure 1 and figure 2 As shown, this design mainly includes the board surface and the frame around the board surface. The board surface is composed of a plurality of horizontally arranged slats (101); The frame (102) vertically arranged on the side a...

Abstract

The invention relates to a batten type automatic overturning back cleaning blackboard which is mainly composed of a board surface, a frame around the board surface and a power input mechanism. The board surface is composed of a plurality of horizontally arranged battens, mutually buckled protrusions or grooves are arranged at the positions of contact surfaces of the adjacent battens, and the frame is composed of a static frame, side frames and a movable frame. Board surface renewal mechanisms are arranged in two side frames respectively, sliding bodies are arranged at two ends of the movable frame, mandrels are arranged at two ends of the battens respectively, and the sliding bodies and the mandrels are respectively connected with the board surface renewal mechanisms. First driving bodies are arranged in the two side frames respectively, are driven by the power input mechanism and are connected with the board surface renewal mechanisms. By driving the movable frame and the plurality of horizontally arranged battens through the first driving bodies in the two side frames, separation of the movable frame, the battens and the static frame is achieved, then the battens are overturned for 180 degrees, integrated press fit is performed finally, cleaning of the back side is finished while normal teaching use of the visual board surface is achieved, and accordingly the problems which occur in blackboard use at present are solved.

Description

technical field [0001] The invention relates to a slatted blackboard with automatic flipping and back cleaning, which belongs to a blackboard for teaching. Background technique [0002] Currently, the teaching blackboard work surface is a fixed surface. After using the blackboard writing, use a dry eraser or a wet eraser to erase the handwriting, and then write again. [0003] The disadvantages of existing blackboards are: when using a dry-type eraser to remove handwriting, there is a lot of dust in the room, which is not conducive to air cleaning, the physical and mental health of teaching staff and the maintenance of indoor instruments; After drying, it can be used again. Because the blackboard eraser has no self-cleaning property, these two ways of wiping the blackboard are not thorough in cleaning, and at the same time affect the teaching effect, rhythm and cultural atmosphere. [0004] Existing a lot of solutions for the above problems, the effect is all unsatisfacto...
