The invention discloses a movable writing board. The movable writing board comprises a frame assembly, a fixed-movable assembly and a sliding device; the fixed-movable assembly comprises a fixed boardand a movable board and further comprises a sliding track-changing structure; the sliding track-changing structure comprises a left-right sliding groove and a front-rear guiding groove; the front-rear guiding groove comprises a left-right straight-direction section and a front-rear turning section, wherein the head end of the front-rear turning section is connected with the left-right sliding groove, and the tail end of the front-rear turning section extends to the rear side of the side away from the left-right straight-direction section; and the sliding device comprises a left-right movementassembly and a front-rear movement assembly, wherein the left-right movement assembly is slidably connected with the left-right sliding groove, the front-rear movement assembly is slidably connectedwith the front-rear guiding groove, and the movable board is connected with the front-rear movement assembly. When the front-rear movement assembly is at the left-right straight-direction section, thefront-rear distance between the movable board and the fixed board is not changed, when moving to the front-rear turning section, the front-rear movement assembly can move backwards, thus the movableboard can get close to the frame assembly, the front-rear position of the movable board is changed, and the movable board and the fixed board can be flush.
Description
technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a movable writing board. Background technique [0002] The movable writing board has a fixed board and a movable board. The fixed board and the movable board are arranged front and back. When the electronic display device is used, the movable board can be moved to the front side of the electronic display device, so that writing can be done on the movable board and the fixed board. [0003] In the existing portable writing board, the movable board can only move left and right. When the movable board moves to the front side of the electronic display device, the movable board is higher than the fixed board, and continuous writing on the movable board and the fixed board is impossible, and the visual experience is also poor. poor. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. F...
