Description
Technical field
The utility model relates to a kind of English-teaching aid, especially a kind of Novel English teaching blackboard.
Background technology
Student is in learning English, for English word memory and write extremely important, teacher needs correct guiding and demonstration in teaching, in word is resolved, usual teacher adopts chalk and ruler first on blackboard, to draw four equidistant line lattice, then write words in four line lattice, draw four line lattice not only to bother but also time-consuming, usually not very standard, student can not be given direct vision thoughts and feelings, affect the learning efficiency of student, be unfavorable for progress and the effect of teaching, unresolved the problems referred to above notification number is that the utility model patent of CN 203210952 U discloses a kind of blackboard for English teaching, although certain effect is played in this invention in actual applications, but still have the following disadvantages: 1, first must ensure before setting-out that each the root chalk in chalk clamp can contact with blackboard, the position of the adjustment chalk clamp that therefore requires a great deal of time, if secondly in line drawing process, chalk is fractureed, or when there is blackboard surface irregularity, just cannot draw four complete line lattice, 2, needing teacher manually to operate when setting-out, is so waste the time of attending class, and two come to be the workload increasing teacher, teacher can be made to feel tired, thus affect classroom efficiency.
Summary of the invention
Technical assignment of the present utility model is for above the deficiencies in the prior art, and provides a kind of Novel English teaching blackboard.
The utility model solves the technical scheme that its technical problem adopts: a kind of Novel English teaching blackboard, comprise blackboard body, line drawing ruler, be arranged on the slide block on described line drawing ruler, be arranged on the chalk clamp on described slide block in addition, and the snap ring be enclosed within outside described chalk clamp, wherein on described line drawing ruler, be provided with controller, micromachine is provided with at described line drawing ruler top, electric expansion bar is provided with in described slide block, push pedal is provided with in described electric expansion bar front end, pressure sensor is provided with between described push pedal and described electric expansion bar, described push pedal is connected with described chalk clamp by spring, at input connection control handle and the described pressure sensor of described controller, output is connected with described micromachine and electric expansion bar.
Advantage of the present utility model: 1, first by controlling the flexible of electric expansion bar, control the distance between chalk clamp and blackboard, and pressure during setting-out between chalk and blackboard, each goes adjustment not need teacher, time of having saved improves operating efficiency, secondly, fracture if there is chalk in line drawing process or blackboard irregular situation time, spring can play certain cushioning effect and ensure the complete of setting-out, then by the flexible distance just can adjusted fast between chalk clamp and blackboard of electric expansion bar; 2, when setting-out, teacher can control electric rotary by joystick, thus drives line drawing ruler to move striping jobs, easy to operate, not only alleviates the workload of teacher, and improves the efficiency on classroom well.

Fig. 2 is the connection diagram of the utility model slide block and chalk clamp.
Fig. 3 is the utility model control framework figure.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described below.
As shown in Figures 1 to 3, a kind of Novel English teaching blackboard, comprise blackboard 1, line drawing ruler 2, be arranged on the slide block 6 on line drawing ruler 2, be arranged on the chalk clamp 3 on slide block 6 in addition, and the snap ring 4 be arranged in chalk clamp 3, wherein on described line drawing ruler 2, be provided with controller 9, micromachine 10 is provided with at described line drawing ruler 2 top, electric expansion bar 7 is provided with in described slide block 6, push pedal 5 is provided with in described electric expansion bar 7 front end, pressure sensor 8 is provided with between described push pedal 5 and described electric expansion bar 7, described push pedal 5 is connected with described chalk clamp 3 by spring 11, at input connection control handle and the described pressure sensor 8 of described controller 9, output is connected with described micromachine 9 and electric expansion bar 7.
Its operation principle is: first in controller 9, set suitable range of pressure values, teacher is when picture four line lattice, only need the setting-out button pressed on joystick, then controller 9 will control motor 10 start rotate, thus it is mobile to drive line drawing ruler 2 to start, in line drawing process, the force value detected is passed to controller 9 by pressure sensor 8, controller 9 is by contrasting with the data of setting, fracture if there is chalk when setting-out, the force value that so pressure sensor 8 detects will be less than the minimum pressure values of setting, now prove that chalk does not contact with blackboard 1, striping jobs cannot be completed, control motor 10 stops operating by this Time Controller 9, control electric expansion bar 7 to start to extend simultaneously, by the time after the force value that pressure sensor 8 is checked through is greater than the minimum pressure values of setting, controller 9 just can rotate from new control motor 10, by the time when the force value that detects of pressure sensor 8 is the same with the most suitable force value of setting, controller 9 will control electric expansion bar 7 to be stopped extending, when meet blackboard 1 has " convex closure " time, because there is spring 11, chalk is avoided to be fractureed so certain cushioning effect can be played, when the force value that pressure sensor 8 detects is greater than the maximum of setting, prove that chalk has by the danger of this section, control electric expansion bar 7 starts to shorten by this Time Controller 9, the pressure between chalk and blackboard 1 is reduced with this, by the time the force value that detects of pressure sensor 8 identical with the most suitable value of setting after, control electric expansion bar 7 stops shortening by controller 9, whole process is all Automatic Control, simple to operation.
