Abstract
The utility model discloses a blackboard groove, comprising a concave type groove. The concave type groove is formed with a tank for storing liquid with an opened mouth at an upper end and the other ends surrounded together. The surface of the groove mouth of the concave type groove is embedded with a mask body which takes the shape of a concave and the groove surface is provided with a powder via-hole. One end of the groove can be provided with a gate for discharging the liquid. With the present functions of the blackboard kept, the blackboard groove can effectively solve the problem of the dust absorption of the blackboard groove. And the blackboard groove is convenient and sanitary to use and wash.
Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to the blackboard groove of blackboard lower edge.
Background technology
For the blackboard that uses in the present teaching, the trough body structure of blackboard lower edge and function are still continuing traditional function, promptly be used for putting the chalk dust of landing on chalk, blackboard eraser and the collection blackboard, because whole cell body is open by design, so the inside deposit the chalk dust that falls unavoidably can because ventilate, local air flow changes and in time cleaning etc. is former thereby cause dust pollution, even bring out breathing problem, thereby numerous teachers and students' hygiene and health are caused harmful effect.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of clean type blackboard groove that can effectively solve the existing existing above-mentioned deficiency of blackboard groove, and its technical problem to be solved can be implemented by the following technical programs.
A kind of blackboard groove comprises the matrix cell body, and it is uncovered that described concave groove body forms a upper end, and all the other respectively hold the liquid bath of putting that surrounds mutually; Described matrix cell body notch face is embedded with and is the cover body that concave and groove face are provided with the powder through hole.
Further, described cell body one end is provided with the fluid discharge gate.
Described cover body can be the wire netting cover.
Adopt the blackboard groove of this technical scheme, under the situation that keeps blackboard groove existing capability, can effectively solve the dust suction problem of blackboard groove, use and clean all very convenient, health.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model being done one describes in detail.
Fig. 1 is the structural representation of blackboard grooved profile described in the utility model.
The specific embodiment
Blackboard groove as shown in the figure, the blackboard groove is made concave groove, and it is uncovered that matrix cell body 1 forms a upper end, and all the other each ends surround mutually puts liquid bath 11, the gate that fluted body body 1 one end settings can be opened.Put liquid bath 11 the insides and discharge water and be used to adsorb chalk dust, when needs cleaned, the gate opening of an end discharged water.Groove upper cap metal guard 12, this metal guard 12 forms a cover body, and cover body is fluted body, but more shallow, is used to place chalk 2 and blackboard eraser, and the chalk dust when using at ordinary times just can enter in the water by the slit on the cover body.
This utility model has solved the problem that blackboard groove dust flies upward, and the place that makes chalk and blackboard eraser place is more cleaned.
