Abstract
The utility model discloses a novel blackboard, which comprises a blackboard frame and a blackboard surface, wherein the blackboard surface is hinged on the blackboard frame. Two rotating shafts are fixed on the left side and the right side of the blackboard surface; the two rotating shafts are hinged in two mounting holes of the blackboard frame in a clearance fit manner; a plurality of raised clamping points are formed on the inner surface of each mounting hole; and a plurality of clamping holes matched with the clamping points and capable of fixing the rotating shaft are formed on the outer circumference surface of each rotating shaft. The blackboard surface of the novel blackboard is capable of rotating around the blackboard frame, thereby enabling a user to rotate the blackboard surface in various angles for more comfortable writing.
Description
Technical field:
The utility model relates to a kind of teaching aid, relates to a kind of new type blackboard in particular.
Background technology:
Blackboard is a kind of realia indispensable in the classroom, it generally is made of frame and plate face, the plate face is used for writing, and existing blackboard panel is fixed, and this blackboard panel is parallel with blackboard framework, but such blackboard panel is when writing, comfortable inadequately, and a lot of not enough people of height, effort not only write, also reach the top of blackboard panel, caused very big waste.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of new type blackboard is provided, and its blackboard panel can rotate around blackboard framework.Technology solution of the present utility model is as follows:
A kind of new type blackboard comprises blackboard framework, blackboard panel, and described blackboard panel is hingedly mounted on the described blackboard framework.
Described a kind of new type blackboard, two sides are fixed with two rotating shafts about described blackboard panel, in two installing holes that are hinged on described blackboard framework of these two rotating shaft matched in clearance, each installing hole inner surface all has the stuck point of a plurality of projectioies, and the outer circumference surface of each rotating shaft all has with these stuck points match makes the hole clipping that rotating shaft is fixed.
Described a kind of new type blackboard, described blackboard panel is fixed with two horizontal line slideways in the longitudinal direction, be fixed with a vertical line slideway on the slide block of these two horizontal line slideways, a blackboard eraser is fixed on the slide block of this vertical line slideway, and the upper surface of the bottom surface of this blackboard eraser and described blackboard panel contacts.
Described a kind of new type blackboard, the stuck point of each installing hole inner surface projection is six, the hole clipping that makes rotating shaft be fixed that the outer circumference surface of each rotating shaft and these six stuck points match also is six.
Described a kind of new type blackboard, described two horizontal line slideways and described blackboard panel are isometric, and one of them is installed in the upper side place of the upper surface of described blackboard panel near blackboard panel, and another is installed in the downside place of the upper surface of described blackboard panel near blackboard panel.
The utility model beneficial effect is:
The blackboard that this is novel, its blackboard panel can rotate around blackboard framework, makes the user as required blackboard panel to be rotated a plurality of angles, makes when it is write again more comfortable; This novel blackboard in addition, its blackboard eraser is mounted on the blackboard panel, utilize line slideway make its can blackboard laterally, vertically move freely, blackboard panel is cleaned freely, very convenient.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is this novel structural representation;
Fig. 2 is this novel A-A cutaway view.
The specific embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 1,2, and a kind of new type blackboard comprises blackboard framework 1, blackboard panel 2, and described blackboard panel is hingedly mounted on the described blackboard framework.
Two sides are fixed with two rotating shafts 3 about described blackboard panel, in two installing holes 4 that are hinged on described blackboard framework of these two rotating shaft matched in clearance, each installing hole inner surface all has the stuck point 401 of a plurality of projectioies, and the outer circumference surface of each rotating shaft all has with these stuck points match makes the hole clipping 301 that rotating shaft is fixed.Like this, when blackboard panel rotates around blackboard framework, the sound of " card reaches ", " card reaches " is arranged, utilize the cooperation of hole clipping and stuck point, can make blackboard when rotating, stay, and can not rotate easily after stopping, be user-friendly for and write in a plurality of positions.
Described blackboard panel is fixed with two horizontal line slideways 5 in the longitudinal direction, be fixed with a vertical line slideway 6 on the slide block of these two horizontal line slideways, a blackboard eraser 7 is fixed on the slide block of this vertical line slideway, and the upper surface of the bottom surface of this blackboard eraser and described blackboard panel contacts.
The stuck point of each installing hole inner surface projection is six, and the hole clipping that makes rotating shaft be fixed that the outer circumference surface of each rotating shaft and these six stuck points match also is six.
Described two horizontal line slideways and described blackboard panel are isometric, and one of them upper surface that is installed in described blackboard panel is near the upper side place of blackboard panel, and another is installed in the downside place of the upper surface of described blackboard panel near blackboard panel.So, make blackboard eraser to move in that the x of blackboard axle, y direction of principal axis are cofree, clean blackboard panel also become very easily.
