Embodiment 1

[0020] The embodiment of this easily modifiable magnetic drawing board is as figure 1 As shown, the easily modifiable magnetic drawing board includes a bottom frame 1, and a drawing panel 2 is covered on the top of the bottom frame 1; and iron powder; the drawing panel 2 is a conventional component and can be purchased directly; the bottom frame 1 is densely covered with miniature sliding chambers 10, and the miniature sliding chambers 10 are provided with permanent magnetic sliders 3 that can slide up and down freely; During the sliding process of the permanent magnet slider 3, each side wall sticks to each inner wall of the miniature sliding cavity 10, that is, the gap fit between the permanent magnetic slider 3 and the inner wall of the miniature sliding cavity 10 maintains a small gap, and the gap is 0.1mm-0.3mm, even if the permanent magnetic slider 3 sticks to the miniature sliding chamber 10, the sliding resistance of the permanent magnetic slider 3 should be kept at a ...

Embodiment 2

[0023] Embodiment 2 of this easily modified magnetic drawing board is as figure 2 As shown, in the second embodiment, the easily modifiable magnetic drawing board includes a bottom frame 1, and the top of the bottom frame 1 is covered with a drawing panel 2; There are white mucus and iron powder inside; the bottom frame 1 is densely covered with miniature sliding chambers 10, the miniature sliding chambers 10 are completely sealed and filled with water, and each miniature sliding chamber 10 is equipped with permanent magnets that can move up and down freely Slider 3.

[0024] For the easily modifiable magnetic drawing board in the above two embodiments, all can adopt image 3 The first embodiment of the magnetic pen shown operates. For embodiment one of the magnetic pen, such as image 3 As shown, the magnetic pen includes a penholder 41, the two ends of the penholder 41 are respectively provided with a writing end 42 made of a weak permanent magnet, and a modification end...

Abstract

The invention provides a magnetic drawing board with easy correction. The magnetic drawing board comprises a bottom frame, wherein a drawing panel covers on the bottom frame; miniature sliding cavities are densely distributed in the bottom frame and are internally provided with permanent-magnetic sliding blocks capable of sliding up and down freely; in the sliding process, all the side walls of the permanent-magnetic sliding blocks are stuck on all the inner walls of the miniature sliding cavities; the bottom parts and the upper parts of the miniature sliding cavities are respectively providedwith first air holes and second air holes communicated with the outside; the magnetism of the permanent-magnetic sliding blocks meets the following conditions that when the permanent-magnetic slidingblocks are positioned at the bottom parts of the miniature sliding cavities, the magnetic attraction force of the permanent-magnetic sliding blocks for iron powder in the miniature cavities oppositeto the permanent-magnetic sliding blocks is less than the resistance of white viscose liquid for the movement of the iron powder, and when the permanent-magnetic sliding blocks are positioned at the upper parts of the miniature sliding cavities, the magnetic attraction force of the permanent-magnetic sliding blocks for the iron powder in the miniature cavities opposite to the permanent-magnetic sliding blocks is less than the resistance of the white viscose liquid for the movement of the iron powder. The magnetic drawing board and a magnetic pen provided by the invention can be convenient to clear image-text contents of any local position on the drawing board.

Description

technical field [0001] The invention relates to the field of stationery and sports articles, in particular to a magnetic drawing board. Background technique [0002] The magnetic drawing board is a common cultural, sports and entertainment product. It includes a panel composed of honeycomb-like micro-cavities. White mucus and iron powder are arranged in each micro-cavity; Permanent magnetic strip: After the permanent magnetic strip scrapes across the back of the panel, all the iron powder in the panel is attracted to the back of the panel, so that the graphic on the panel is cleared and the front of the panel appears white. However, this kind of magnetic drawing board can only clear the graphics and texts on the panel in a large area, and cannot clear the partial content on the panel, so that it is impossible to realize partial modification of the graphics and texts on the panel. Contents of the invention [0003] In view of the above problems, the object of the present i...
