Problems solved by technology

[0014] In order to solve the above problems, the present invention provides a magnetic display board, which is placed on the front end of a magnetic pen for children, in view of the fact that this magnetic display board is mainly used by young children, and the first purpose is to ensure the physical safety of young children and reduce the risk. When the drawing surface of the magnetic drawing board is strongly pierced or knocked, the drawing surface will not be easily damaged, and the bonding between the drawing surface and the honeycomb core board will not be easily damaged, thereby ensuring the safety of the child's body. At the same time, clear drawing lines can always be displayed, and In case of disposal, it can be disposed of safely without causing public hazards

Embodiment Construction

[0039] figure 1 is a perspective view of a magnetic display panel 1 according to the present invention, figure 2 is its cross-sectional view, image 3 It is an exploded perspective view, the magnetic display board 1 uses a honeycomb core board 5 as a core board with a plurality of units 4 and seals it between the face plate 2 and the core board receiver 3, and encloses the inside of each unit 4 of the honeycomb core board 5 containing Plastic dispersion liquid of magnetic particles7.

[0040] In the above-mentioned structure, contact the front end of the magnetic pen (not shown in the figure) with the drawing surface (the surface of the core board receiving body 3), or move left and right to be equipped with a eraser such as a magnet that is freely slidably arranged on the inner side of the panel 2 The word stick (not shown in the figure) can make the magnetic field act in the plastic dispersion liquid 7, make the magnetic particles float to the painting surface or leave the...

Abstract

A magnetic display panel capable of ensuring safety to the body of an infant, permitting drawing of clear lines and ensuring safe disposal thereof. A magnetic display panel (1) includes a core housing (3) which has a peripheral edge (3a) formed to have an increased height and is formed therein with a recess (8), a plate-like face member (2) arranged so as to cover the recess (8), and a core block (5) provided with a number of cells (4) in which a plastic dispersion liquid (7) containing magnetic particles is encapsulated and sealedly joined between the core block (5) and the plate-like face member (2) by an adhesive. The core housing (3) and plate-like face member (2) are each made of olefin synthetic resin. One of the core housing (3) and plate-like face member (2) constitutes a drawing faceplate which is formed to be transparent or semi-transparent. The core block (5) is formed of pulp made paper.

Description

technical field [0001] The present invention mainly relates to a magnetic display board for children's drawing and its manufacturing method, and more particularly to an improved magnetic display board whose structure is improved by compounding the materials of the core board and members sealing from both sides thereof and its manufacturing method . Background technique [0002] Generally, as a drawing board for infants, there is known a magnetic drawing board that seals a honeycomb core having a plurality of hexagonal cells between a transparent or translucent drawing board (substrate) and a panel member facing it. plate, enclosing the plastic dispersion liquid containing the magnetic particles in each of the above units. [0003] Because the front end of the magnetic pen is in contact with the painting surface, the magnetic field acts on the dispersion liquid, and the magnetic particles that sink to the bottom float to the painting surface, and the pictures or characters a...
