Abstract

The utility model discloses a writing board with display which is realized by that the writing board with display is additionally provided with a writing board and a magnetic electric bead is improved on the basis of the existing discoloration writing board. The arrangement of the writing board with display is convenient for writing and is cooperated with the display board to play the actions of magnifying writing and optional colours. The structure of the magnetic electric bead is changed into the structure of a bead electric pillar, which simplifies the structure. The utility model which is widely suitable for teaching, advertisement, etc. has the advantages of easy production, low cost, etc.

Description

Writing board with display

The utility model belongs to teaching aid and makes the field.

Prior art in the utility model prior art field is further to improve to realize on the application number that the utility model applicant declares is No. 89217776.4 the basis of " variable color clipboard ".The variable color clipboard is wiped by lattice frame, catch, magnetoelectricity pearl, base plate, slide, lettering pen and background color and is formed, base plate is positioned at the bottom of lattice frame, the magnetoelectricity pearl is arranged in the lattice of lattice frame and turns, and catch is positioned on the magnetoelectricity pearl, and slide is positioned on the catch.

Purpose of design of the present utility model is: design and a kind ofly write and the demonstration clipboard that shows at display board by clipboard.

Design of the present utility model is: show that clipboard is to be made of display board, lettering pen, end wiping and clipboard.Clipboard is connected with multi-core socket on the display board by lead-in wire and multi-pin connector.1. display board is made up of slide, frame, catch, lattice frame, magnetoelectricity post, axis of a cylinder, base plate and multi-core socket.Base plate adopts printed board, the copper face that covers on its printed panel is divided into several and covers the copper sheet grid and cover the copper sheet grid and cover between the copper sheet grid to not conducting, each covers and is welded with a lead-in wire on the copper sheet grid, and another termination of its lead-in wire is positioned at the terminals of the multi-core socket on the frame; The magnetoelectricity post is by having magnetic Shape skeleton and two sheet metals that have a positive and negative electric charge constitute, and positive and negative electric charge sheet metal is embedded in respectively On the skeleton,

The orthogonal fan-shaped skeleton of skeleton dashes respectively has N, S polarity magnetic, the sheet metal of N, S pole-face and positive and negative electric charge to adopt color not of the same race to show (as: red, yellow, blue, green, black etc. color) respectively; Base plate is positioned at frame, axis of a cylinder is through on the lattice frame and is positioned on the axis of a cylinder of lattice frame and all is with a magnetic post, lattice frame be positioned on frame and the base plate and each lattice of lattice frame all with base plate on each to cover the copper sheet grid corresponding, catch is positioned on the magnetic post, and slide is positioned on the catch.Clipboard be by inner housing, conduction panel, storage plate, multi-core socket, write the lid and insulating barrier constitute, the storage plate adopts the metallic rod of mutual insulating to constitute and is positioned at housing, writing lid is positioned on the housing, it writes the intrinsic rubber layer of medial surface of lid, write and touch mutually with the plate face of storage plate after lid is closed, insulating barrier is close to the bottom surface of storage plate, conduction panel adopt the metal bar of mutual insulating to constitute and be close on the insulating barrier and and each metal bar of storage plate corresponding one by one, bottom and line end that multi-core socket is positioned at housing are connected with the metal bar of conduction panel.3. lettering pen is on the basis of existing propelling pencil its casing diameter increase, static lead for retractable pencil to be increased slightly, and the end of button 22 increases a solid rubber and realizes.4. end wiping is to be made of brush, metal bar, brush body and lead, and brush adopts finer wire and is positioned at the end of brush body, and metal bar is positioned at brush body and left end is connected with brush, and right-hand member is connected with lead, the other end ground connection of lead.5. after operation principle: a, the lead 24 that has a multi-pin connector are connected the multi-core socket of display board 8 and clipboard 11, writing of clipboard covered 13 opens, adopt lettering pen 23 on the plate face of its storage plate 12, to write then, this moment lettering pen with electrostatic induction be delivered to display board to conduction panel 18 by multicore connector and lead, make magnetic post in the display board turn to needed can constituting word or picture (repel each other according to the same sex, the principle that there is a natural attraction between the sexes rotates the magnetic post).B. also the storage plate can be taken out write outside being placed in the clipboard, cover and write lid, and reach the purpose that display board is shown.C, also can on display board, directly write with lettering pen.6. lettering pen described in the utility model divides positive and negative electric charge lettering pen, N, S utmost point lettering pen; Wipe at the bottom of wiping and dividing positive and negative electric charge at the described end, wipes at the bottom of N, the S utmost point.

The utility model 1. can demonstrate word or figure along with lettering pen is write on the structural design on clipboard on the display board, and its tone difference; 2. can wipe the writing of wrongly writing when writing on the clipboard (or display board) at any time and not influence other writing; 3. write after the storage plate in the clipboard can being taken out and place in the clipboard and on display board, demonstrate the content of clipboard.
