Abstract

The utility model discloses a novel writing instrument, which is characterized by consisting of a writing board (1), a writing pen (2) and a board eraser (3). The writing board (1) consists of a bottom board (4) and a semitransparent white board (5); a plurality of slide ways (7) are uniformly and densely distributed in a cavity (6) between the bottom board (4) and the semitransparent board (5); a fuscous magnetic ball (8) is arranged in each slide way (7); the end head of the writing pen (2) is provided with a magnetic head (9) and the magnetism of the magnetic head is different from that of the fuscous magnetic ball (8); and the end face of the board eraser (3) is provided with a magnetic board (10) and the magnetism of the magnetic board is the same as that of the fuscous magnetic ball (8). The novel writing instrument has simple and masterly structure and convenient operation, does not generate any dust pollution during writing and erasing and can protect the health of teachers and students.

Description

Novel writing appliance

Technical field

The utility model relates to a kind of teaching aid, especially a kind ofly produces dust such as chalk dust, the novel writing appliance of protection teacher and student health of human body writing Shi Buhui.

Background technology

Blackboard and chalk are people's requisite a kind of teaching aids when carrying out focusing study, it possesses advantage such as writes, wiping is convenient, fast, but simultaneously, when writing with wiping, the chalk dust that flies upward can be invaded in the respiratory system of Faculty and Students, in this dust atmosphere, can cause the disease of various respiratory tracts aspect for a long time, especially to the teacher, very harmful.Therefore be badly in need of now wanting a kind of can either being convenient for people to write, can quickly literal or figure be wiped again, can not produce any dust pollution simultaneously, the healthy novel writing appliance of protection teacher and student.

Summary of the invention

The utility model is in order to solve existing in prior technology the problems referred to above, to provide a kind of simple in structure, ingenious, easy to operate, all can not produce any dust pollution when writing with wiping, can protecting the healthy novel writing appliance of teacher and student.

Concrete solution of the present utility model is: a kind of novel writing appliance, it is characterized in that: described novel writing appliance is made up of clipboard 1, lettering pen 2 and blackboard eraser 3, clipboard 1 is made up of base plate 4 and translucent blank 5, in the cavity 6 between base plate 4 and translucent sheet 5, evenly be densely covered with a plurality of slideways 7, all be placed with a dark magnetic ball 8 in each slideway 7, the termination of lettering pen 2 is provided with magnetic head 9, the magnetic of its magnetic and dark magnetic ball 8 is different, the end face of blackboard eraser 3 is provided with magnetic sheet 10, and its magnetic is identical with the magnetic of dark magnetic ball 8.

The utility model is compared with prior art, has following advantage:

This device simple in structure, utilized the principle of magnetic dexterously, write on the clipboard and wiping to be implemented in, and in whole process, can not produce any dust pollution, protected the health of human body of Faculty and Students effectively, the writing appliance of this version in use can not consume chalk as traditional blackboard and chalk simultaneously, saves resource; This device possesses extensive market prospects, very helps applying in the art.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: novel writing appliance is made up of clipboard 1, lettering pen 2 and blackboard eraser 3 three parts; Clipboard 1 is two-layer single cavity configuration, and it is made up of base plate 4 and translucent blank 5, is cavity 6 between base plate 4 and the translucent sheet 5, evenly is densely covered with a plurality of slideways 7 in cavity 6, all is placed with a dark magnetic ball 8 in each slideway 7; As shown in Figure 3, the termination of lettering pen 2 is provided with magnetic head 9, and the magnetic of its magnetic and dark magnetic ball 8 is different; As shown in Figure 4, the end face of blackboard eraser 3 is provided with magnetic sheet 10, and its magnetic is identical with the magnetic of dark magnetic ball 8.

The course of work of the novel writing appliance of the utility model embodiment is as follows: under the original state, dark magnetic ball 8 in all slideways 7 all leans against base plate 4 one sides, write or draw a design at the outer surface of translucent sheet 5 with the magnetic head 9 of lettering pen 2 ends, because magnetic head 9 is different with the magnetic of dark magnetic ball 8, under the principle that there is a natural attraction between the sexes, magnetic head 9 is passed by the dark magnetic ball 8 of track just under the effect of magnetic force, in slideway 7, slide, and contact with the interior survey of translucent blank 5, a plurality of so dark magnetic ball 8 just can demonstrate the track that magnetic head 9 is passed by on the outer surface of translucent blank 8, form literal or pattern; When needs during with literal or pattern wiping, the outer surface that the magnetic sheet 10 of blackboard eraser 3 end faces is abutted in translucent blank 8 moves back and forth, because the magnetic of magnetic sheet 10 is identical with the magnetic of dark magnetic ball 8, under the principle that the same sex is repelled each other, magnetic sheet 10 is passed by the dark magnetic ball 8 of track just under the effect of magnetic force, in slideway 7, slide, and abut against the inner surface of base plate 4, look from the front of clipboard 1 like this, writing and pattern be just by wiped clean, can carry out writing or the drafting of pattern of literal next time.
