Abstract
The utility model relates to a blackboard belongs to teaching aid technical field. A teaching chalkboard, its characterized in that includes the body, this internal horizontal line pipe that transversely is provided with a plurality of parallels, this internal vertical vertical line pipe that is provided with a plurality of parallels, the one end of horizontal line pipe is connected with the horizontal line pump, the other end of horizontal line pipe is connected with liquid tank, the one end of vertical line pipe is connected with the vertical line pump, the other end of vertical line pipe is connected with liquid tank. The utility model discloses set up horizontal line pipe and vertical line pipe to let in the liquid that has fluorescent substance or with the liquid of the great colour of blackboard body colour difference, make people can observe horizontal line pipe and the projection of vertical line pipe on the blackboard body surface, make the blackboard body surface a plurality of horizontal lines and vertical line appear.
Description
Technical field
The utility model relates to a kind of blackboard, belongs to teaching aid technical field.
Background technology
In English teaching, write the English letter step that is absolutely necessary, even in university classroom, draw four line three latticeAlso be common occurrence feelings. In practice, the conventional ruler of teacher draws many parallel lines, uses as four line three lattice, long like thisTime line, not only tired but also bother, extend instructional blocks of time, also setting-out is easily drawn tiltedly. In addition, in language teaching, serve as a teacher and needWhile wanting writing Chinese characters, need to use matts, equally also need on blackboard, draw matts. Equally, waste time and energy.
Summary of the invention
The purpose of this utility model is addressing the above problem exactly, while providing one can meet English and language teaching,Can show the blackboard of four line three lattice and matts.
The technical scheme that the utility model provides is:
A kind of blackboard for teaching, comprises body, is horizontally arranged with some parallel horizontal line pipes, described body in described bodyInside vertically be provided with some parallel vertical line pipes, one end of described horizontal line pipe is connected with horizontal line pump, the other end of described horizontal line pipeBe connected with fluid box, one end of described vertical line pipe is connected with vertical line pump, and the other end of described vertical line pipe is connected with fluid box.
A kind of blackboard for teaching, comprises body, is horizontally arranged with some parallel horizontal line pipes, described body after described bodyVertically be provided with afterwards some parallel vertical line pipes, one end of described horizontal line pipe is connected with horizontal line pump, the other end of described horizontal line pipeBe connected with fluid box, one end of described vertical line pipe is connected with vertical line pump, and the other end of described vertical line pipe is connected with fluid box.
Concrete, all horizontal line pipes are in the same plane, and all vertical line pipes are in the same plane, described horizontal line pipe structureThe plane that the plane parallel becoming forms in described vertical line pipe.
Concrete, between horizontal line pipe and horizontal line pump, be provided with valve, between vertical line pipe and vertical line pump, be provided with valve.
Concrete, the distance between described horizontal line pipe is equal, and the distance between described vertical line pipe equates.
The utility model arranges horizontal line pipe and vertical line pipe, and pass into the liquid of fluorescent material or with this body colour of blackboardThe liquid of poor larger color, makes people can observe horizontal line pipe and vertical line pipe in the projection of blackboard body surface, makes blackThere is some horizontal lines and vertical line in plate body surface. By by-pass valve control, make to be full of in vertical line pipe and horizontal line pipe liquid or for emptyPipe.

Detailed description of the invention
A kind of blackboard for teaching, comprises body, is horizontally arranged with some parallel horizontal line pipes, described body in described bodyInside vertically be provided with some parallel vertical line pipes, one end of described horizontal line pipe is connected with horizontal line pump, the other end of described horizontal line pipeBe connected with fluid box, one end of described vertical line pipe is connected with vertical line pump, and the other end of described vertical line pipe is connected with fluid box. AllHorizontal line pipe is in the same plane, and all vertical line pipes are in the same plane, and the plane parallel that described horizontal line pipe forms is in describedThe plane that vertical line pipe forms. Between horizontal line pipe and horizontal line pump, be provided with valve, between vertical line pipe and vertical line pump, be provided with valve. InstituteState distance between horizontal line pipe and equate, the distance between described vertical line pipe equates.
Liquid in described fluid box be with the liquid of fluorescent material or with the liquid of the larger color of blackboard body aberrationBody.
By by-pass valve control, adjust the annexation between vertical line pump and gateway and the fluid box of horizontal line pump simultaneously, makeBe full of liquid in vertical line pipe and horizontal line pipe or be blank pipe. Like this, four shown line three lattice and fields on described blackboard for teachingThe size of word lattice.
Embodiment 2
Be with the difference of embodiment 1, horizontal line pipe and vertical line pipe are positioned at after body.
Finally should be noted that: above embodiment is only in order to the technical solution of the utility model to be described but not to its limitSystem; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field shouldUnderstand: still can modify or part technical characterictic is equal to and is replaced detailed description of the invention of the present utility modelChange; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the technical scheme of the utility model request protectionIn the middle of scope.
