Abstract
The invention is a multifunctional shelf fluorescent tablet consists of a frame, a soleplate, a writing board and a fluorescent writing stick. A cold cathode tube is set inboard and connected with the power source. The colorless and transparent writing board is set on the soleplate with a space between the writing board and the soleplate. The cold cathode tube is installed at the side of the writing board and covered axially with a reflexive shade which affixed to the edges of both the writing board and the soleplate. The ray of the cold cathode tube is focused on the side of the writing board to provide apheliotropic light. Writing or drawing with the stick on the writing board corresponding text or drawings will appear on the board. The invention is simple, inexpensive, light while tough very mobile and no powder pollution. It could be applied to education and children's drawing practicing also it can be used to advertise in pubic place. Drawing with sticks of different color will make out colorful and bright patterns so as to celebrate the festivals.
Description
Technical field
The invention belongs to and write or drawing appliance, office appliance technical field, is a kind of multifunctional frame type fluorescent writing board.
Background technology
Traditional board is only as educational outfit, function singleness, the volume heaviness, carries inconvenience, and writes, causes dust pollution with chalk.For fear of the dust influence healthy to people, various electronic blackboards are come out one after another.By Chinese patent literature disclosed " ZL00230672.7 ", " electronic blackboard ", it is divided into many cells with blackboard, each cell is placed a light emitting diode, utilize the magnetic stripe of diode back to do the control of switch realization to light emitting diode, after connecting power supply, write on panel with a metal bar, promptly corresponding literal or figure can appear.The shortcoming of this electronic blackboard is the magnet-type mechanical switch as key element, and the folding time of switch is longer, and sensitivity is relatively poor; Mechanical contact is easy to wear, and volume of switch is big, so the pixel unit volume is bigger, display precision is relatively poor.Chinese patent " ZL01256861.9 ", " sensitization electronic blackboard and write and wipe annex ", it is to be separated out the chamber that volume equates by light tight parting bead between parallel panel, base plate glass, filling inert gas in chamber, constitute the pixel unit of gas diode formula, and be provided with an optoelectronic switch in each pixel unit, between panel and base plate glass, reserve separate chamber with the parting bead separation, be provided with in this chamber and wipe optoelectronic switch, the orange-colored light that electronic pen sends realizes switch conduction.In the time will wiping, light emitting display sends monochromatic light, makes to wipe switch conduction, and diode is not luminous.This electronic blackboard complex structure, processing technology difficulty, cost are higher, and light emitting diode is limited service life, and one of them or several light emitting diode damage, and will influence whole service life.
Summary of the invention
The objective of the invention is to defective and deficiency at above-mentioned prior art, for society provide a kind of simple in structure, cost is low, light weight is firm, multifunctional frame type fluorescent writing board easy to carry, non-dusting.
The technical solution used in the present invention is for achieving the above object: this multifunctional frame type fluorescent writing board comprises framework, clipboard, base plate and fluorescence lettering pen, madial wall at base plate sets up the cold-cathode tube that links to each other with power supply, water white clipboard is in above the base plate, this clipboard leaves the gap with the sidewall of the bottom plate that cold-cathode tube is housed, make cold-cathode tube be in the side of lettering pen, axial location is coated with a reflection shading strip on cold-cathode tube, it is adhered to board and the bottom edge that cold-cathode tube is housed, and the visible light that cold-cathode tube is sent provides backlight for clipboard; Described cold cathode tube is two, and they are erected at the base plate madial wall that is parallel to each other; Have the groove that to place cold-cathode tube and power circuit plate on the described base plate.Can install liner plate additional below the described clipboard, above the base plate; Can draw above the liner plate at this and to write lattice; Base plate and framework are fixed by screw.
It is light source that the present invention adopts cold-cathode tube, shines to side surface direction by cold-cathode tube, for clipboard provides backlight, makes the clear wash rice of the calligraphy and painting of writing on clipboard as seen.The present invention is simple in structure, cost is low, light weight is firm, easy to carry, and no dust pollution is for board provides a kind of new product.It can be used to do educational outfit or the child of family handwriting practicing drawing, also can be used as the exploitation of public place, also the e-Pointer of available different colours draw colourful pattern bright in luster, the calligraphy and painting fork-like farm tool used in ancient China is dressed up and increase the atmosphere in red-letter day.

Fig. 2 is a reflection shading strip schematic diagram among Fig. 1.
Fig. 3 is a front view of the present invention.
Fig. 4 is a rearview of the present invention.
The specific embodiment
As shown in the figure, the framework 1 and the base plate 5 of this multifunctional frame type fluorescent writing board are screwed, are equipped with clipboard 3 in framework, this clipboard is positioned on the base plate, clipboard is made by colourless transparent material, and it can be a macromolecular material, for example plastics, lucite, also can be glass, preferably make,, highlight to strengthen refraction effect backlight by the firm lucite of light weight.Can also adorn a liner plate 4 between base plate 5 and clipboard 3, if writing lattice is set on liner plate, it can provide support for writing, drawing.Base plate 5 is provided with groove 7 and groove 9, and groove 7 is used for placing wiring board 6, and groove 9 is used for placing cold-cathode tube 2, to avoid because of being subjected to improper external force to cause the superfine cold-cathode tube of caliber cracked.Can select to install 1 to 4 cold-cathode tube according to the intensity of board area size and required light.The used cold-cathode tube of present embodiment is two, cold-cathode tube 2 and cold-cathode tube 2 ', be erected at respectively on the madial wall that base plate is parallel to each other, the edge of clipboard 3 and liner plate 4 leaves the gap with the bottom edge that cold-cathode tube is housed, and makes cold-cathode tube 2 be in the side of clipboard.Cover a reflection shading strip 8 on cold-cathode tube, the bottom of this reflection shading strip is a black shading strip 10, is stained with the reflection bar 11 of white above it.The white reflection bar of reflection shading strip is towards cold-cathode tube, and is pasted on clipboard 3 and base plate 5 edges along its axial location, and cold-cathode tube is covered.Two utmost points of cold-cathode tube are connected with the wiring board output respectively.The plug of supply convertor joins by supply hub and power circuit plate.The 220V civil power is through supply convertor output 12V direct current, and the power circuit of via line plate converts the high voltage micro-current cooling cathode tube electricity consumption of 1100V to then.The power supply conversion portion is the prior art mature technology, can not be described further at this.
During use, connect power supply, the light sideways diffusion that cold-cathode tube sends is because the effect of reflection shading strip can make light concentrate towards the side surface direction of clipboard and shine, for clipboard provides a uniform backlight.On clipboard, write, draw with the fluorescence lettering pen, corresponding literal or figure promptly occur.Its erasing is convenient, and no dust is applicable to that classroom, family or other public place use.
