Abstract
The utility model discloses a rotary type teaching blackboard, which comprises rims on every side. Rollers are arranged on the upper and the lower ends of the rims on both sides of the utility model, and a pad board is fixed on the rims. The writing surface of a soft writing board is pressed closely to the pad board through butt joint soft writing boards sheathed on rollers, and one of the rollers is connected with a rotary device. The soft writing board can spin up and down cyclically through the turning device. The teaching blackboard has the advantages of no restriction on the stature of teachers, convenient and comfortable writing and long detention time of content.
Description
Technical field
The utility model belongs to teaching facilities, relates in particular to protecting teaching writing board.
Technical background
In classroom, universities, middle and primary schools classroom, blackboard must not lack at present, useful " blank " yet.Its structure all is that the hard plate flooring is fixed in the frame, installs on the wall then.Face sheet material is as plank, frosted glass or inferior honorable steel plate etc.This traditional machine made blackboard has many deficiencies: 1, plate face setting height(from bottom) and width are generally all fixed because of the restriction of people's stature, and too high, the teacher can't reach, and be too low, stops student's sight line; 2, because teacher's height does not wait, and low people lifts the arm dysgraphia, high people bends over to squat down real in inconvenient, more can't reach when the student appears on the stage to demonstrate or erase the board, and it is abnormally dangerous to step on stool; 3, plate face width degree is limit, and makes the amount of writing limited.
Summary of the invention
The application's purpose is the deficiency that overcomes existing fixed blackboard, and the teaching " blackboard " of a kind of plate face rotation capable of circulation is provided.
The application's technical scheme is that the frame around it comprises is installed transfer roller at the upper and lower side of both sides frame, fixed-bearing plate on frame, put soft the writing " plate " of butt joint by transfer roller, the writing surface of soft clipboard is close to lining plank, and wherein a transfer roller connects tumbler.Make soft writing " plate " circulating rolling up and down by tumbler.
The application's good effect is: 1, the height of " plate " and width no longer are subjected to the restriction of teacher's stature, can reach the height of classroom metope, scroll up as long as write at suitable height, and the plate face enlarges at double, and the amount of writing is big, does not also stop student's sight line; 2, various statures all suit, and need not lift arm or bend over, and comfortable how writing how need not be with writing with wiping, and retention time is long, is convenient to teaching, also can forward to positively to come even forward the content at the back side to.Only need wipe the out-of-date content that turns over when the amount of writing is very big and get final product, make whole plate face keep continuity.
Description of drawings
Fig. 1 is the schematic diagram of the front view of embodiment, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the profile of another embodiment, and Fig. 4 is the cutaway view after the B portion of Fig. 1 amplifies, and Fig. 5 is the C-C profile of Fig. 4.
The specific embodiment
As shown in Figure 1 and Figure 2: it comprises a frame 1, install transfer roller 2 and following transfer roller 6 at the both sides frame, the transfer roller rough surface has certain frictional force, fixed-bearing plate 4 on the frame of both sides, lining plank 4 will have certain stiffness, in case tremble when firmly writing, soft writing " plate " 3 is enclosed within on two transfer rollers and is docking together.
Being another kind of embodiment as shown in Figure 3, is the deepening to a last embodiment, and mainly being increases several roads axis of guide 9 on side frame, makes soft writing " plate " revolution several times, stores length thereby increase, and further improves the amount of writing.
As shown in Figure 4, the last transfer roller axis hole on the side frame is a slotted hole 7, establishes a vertical core in the side frame, and spring 8 and pad are housed in the vertical core, is mainly used in the rate of tension of automatic adjusting soft board.
In the above-described embodiment, do not draw among the figure structure of tumbler 5.5 one kinds of schemes of tumbler are that employing is electronic, promptly at an end of last transfer roller 2 micromachine are installed, and drag transfer roller by transmission device and rotate.The kind of drive such as gear drive, belt transmission etc.Another kind of scheme is to take manually, promptly at the axle head of following transfer roller 6 hand crank or manual pulley is installed, and is rotated by the manually-operated transfer roller.
Above-described soft board is selected surface abrasion resistance, tension, easily and the flexible material of writing and wiping for use, as the volume property material of waterproof sheet, fibrous interlayer polyester film and so on.Soft " plate " is enclosed within when docking on the transfer roller, can bond, sews up, zip mode all can.
