Description
Technical field
The utility model belongs to blackboard for teaching, specifically refers to a kind of blackboard being applicable to primary school teaching.
Background technology
It is used for teachers ' teaching that each classroom can be provided with corresponding blackboard, scribbled carry out transmission of knowledge by the chalk of different colours on blackboard, can wiped by corresponding blackboard eraser to corresponding letter written with chalk.Along with the progress in epoch, the application of multimedia projector instead of the use of blackboard to a great extent.But as pupil, its cognitive knowledge is comparatively limited, is not suitable for too much adopting multimedia, thus pupil attends class still based on blackboard writing on the blackboard at present.Pupil's height is relatively short, is therefore unfavorable for writing of writing on the blackboard, during upper blackboard answer, can only carry out bottom blackboard.And clear in order to what beneath classmates can be seen, often needing again the content of answer to write on higher position, is very difficult to manage.Therefore, Push-pull blackboard starts to be used.But also need certain height in the push-and-pull process of existing Push-pull blackboard, say from birth for lower primary school, the push-and-pull in use procedure is still more difficult is what realize.And the complicated structure of existing Push-pull blackboard, cost is quite high, and easily breaks down, and this is difficult to be suitable in comparatively remote rural area more.Therefore, carrying out solution for above-mentioned prior art Problems existing is research purpose of the present utility model.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the utility model is to provide a kind of blackboard being applicable to primary school teaching, effectively can solve above-mentioned prior art Problems existing.
The technical solution of the utility model is: a kind of blackboard being applicable to primary school teaching, comprise framework, two pieces of blackboards and one piece of blank, described framework comprises upper location cross bar parallel up and down and lower location cross bar, the both sides of described upper location cross bar and lower location cross bar are connected with two corresponding first radius rods respectively, the centre position of upper location cross bar and lower location cross bar is connected with two corresponding second radius rods, distance between described two second radius rods is the 8-12% of upper location cross bar length, described two second radius rods are in-built is equipped with described blank, described two pieces of blackboards are installed between corresponding first radius rod and the second radius rod respectively, the side that described first radius rod is relative to described second radius rod is respectively equipped with corresponding slide rail, the both sides tumbler of described blackboard has the roller matched with corresponding slide rail, the centre position of described first radius rod, the second radius rod is equipped with corresponding stopper, and the top of described two pieces of blackboards is equipped with the clamp corresponding with corresponding stopper, the lower rear of described two pieces of blackboards is equipped with corresponding locating slot, the location-plate that two of being connected with by spring in the below of cross bar both sides, described lower location are corresponding, and described location-plate is connected in the locating slot of corresponding blackboard respectively, described two pieces of blackboards are respectively equipped with corresponding handle on the position corresponding to the locating slot that it is provided with, and on described handle, device has the button for pressing location-plate.
The outside of described two first radius rods is equipped with corresponding chalk box and blackboard eraser holder.
Advantage of the present utility model: the utility model structure is simple, and push-and-pull process is simple and easy, is suitable for pupil and uses; And the utility model is with low cost, fault rate is extremely low, even if also can be suitable in comparatively remote rural area.After the button press location-plate that student is had by device on handle, blackboard can be pulled down to stopper and block clamp, one can at school time make the height of blackboard adapt to height be convenient to write answer, two can facilitate student after class to the wiping of blackboard, after writing or after wiping, by its handle, blackboard up one is pushed away and makes it reset.Be provided with two pieces of blackboards and one piece of blank in framework of the present utility model, and blank be arranged on centre position, can at school before on blank, write attend class priority and difficulty and the main line of this class, be conducive to the effect improving teaching.
