The four line grids standard is drawn to this blackboard, and easy operation is laborsaving, can absorb the dust in the setting -out to avoid mr and student to absorb the dust.
Description
Technical field
This utility model relates to English teaching appurtenance technical field, draws the blackboard of four line lattice particularly to a kind of English teaching of being easy to.
Background technology
Writing of Chinese is with matts for standard, writing of English, is with four line lattice for standard, in process of English teaching, teacher will not draw four line lattice on blackboard again, because four line lattice are drawn four line lattice and extremely lost time, the aid of existing picture four line lattice is also generally handheld tool, not only not readily portable, and owing to the length of chalker is certain, therefore draw broken string and the drawn four uneven situations of line lattice of unavoidably there will be in four line lattice processes.
English teaching four ruling drawing tool of the prior art, a kind of Novel English teaching equipment as disclosed in CN201410811747.5, including scriber and word plate, described word plate is arranged on bottom described scriber, described scriber includes track gauge, box body, handle and multiple sleeve, one end of described box body is connected with described handle, the uniform other end being set in parallel in described box body of multiple described sleeves, described track gauge is track box, described box body is vertically installed in inside described track gauge, and described word plate abuts with described track gauge.It is disadvantageous in that: need left hand to be pressed against on blackboard by equipment during use, right hand sliding skateboard, and owing to teaching equipment volume is big, operation is wasted time and energy, and the lines of picture are inconsistent, unintelligible.
Chinese utility model patent if number of patent application is 201020655323.1 discloses a kind of simple blackboard eraser, including the slide rail being arranged on the upper and lower two ends of blackboard, being provided with roller in slide rail, swipe is connected with the roller being arranged on slide rail, the bottom surface of swipe is provided with bristle, and the back side of swipe is provided with handle.The length of this swipe is suitable with the width of blackboard, and the handle gripped in swipe can be wiped along blackboard slip swipe.This blackboard eraser solves the problem of erasing monoblock blackboard difficulty, and simultaneously erased speed also increases.But this kind of blackboard eraser needs the handle that people grips in swipe to swipe, people is relatively painstaking in pulling handle process, and automaticity is not high.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of English teaching of being easy to draws the blackboard of four line lattice, four line lattice specifications drawn by this blackboard, simple to operate laborsaving, while setting-out can dust adsorption, thus avoiding teacher and student's dust adsorption.
For reaching above-mentioned purpose, this utility model is by the following technical solutions: a kind of English teaching of being easy to draws the blackboard of four line lattice, including the slide rail being arranged on the upper and lower two ends of blackboard, the slide plate with roller is set in described slide rail, described slide plate is set with the sliding sleeve slided up and down, described sliding sleeve is provided with several through holes holding chalk, described slide plate is provided with mean for the rectangular through-hole of chalk traverse, described slide plate is provided with for compressing the pressure cap of chalk in through hole, described slide plate two ends are respectively provided with at least two roller, the slide rail of described blackboard has tooth bar, the elongated end of described slide plate is provided with motor, driving of described motor is set with, on axle, the driving gear engaged with tooth bar, described sliding sleeve has vacuum cleaner.
Described vacuum cleaner and motor are all connected with Programmable Logic Controller.
It is connected by elastic mechanism between described pressure cap and chalk.
Described elastic mechanism is the spring being arranged in pressure cap.
Described pressure cap and sliding sleeve are threaded connection.
Uniform 4 through holes on described sliding sleeve.
Described through hole longitudinal arrangement is on sliding sleeve.
Bolt on described sliding sleeve.
Compared with prior art, the beneficial effects of the utility model are: the real new blackboard of this practicality in use, during use, regulate the position of sliding sleeve, screwed in place bolt, chalk is inserted sliding sleeve, nut is screwed on sliding sleeve, chalk is pressed on blackboard by the spring in nut, controls motor work by controller, and driven by motor slide plate moves right in slide rail, blackboard draws four line lattice, four line lattice processes of drawing are without hand-held instrument, time saving and energy saving, easy to operate.While motor works, vacuum cleaner works dust absorbing, it is to avoid student and teacher absorb；By spring, chalk is pressed on blackboard, in that context it may be convenient to regulating chalk and be pressed in the pressure on blackboard, in line drawing process, chalk is not easy to fracture, and what is more important chalk different in size all can use.Further, by regulating the upper-lower position sliding on slide plate, in that context it may be convenient on blackboard, four line lattice are drawn in any position, draw four line lattice codes and standards.
