Abstract

The utility model provides a combined type blackboard provided with a chalk dust collecting device which can easily and conveniently collect and clean chalk dust, and the utility model comprises a blackboard outer frame, a fixed board surface A, a fixed board surface B, a movable board surface and a dust collecting device, wherein a track groove is arranged on the lower outer frame of the blackboard for the moving of the movable board surface, a dust dropping hole facing directly downward is arranged at the two ends of the track groove respectively, a dust dropping pipe is arranged in the dustdropping hole, the lower end of the dust dropping pipe extends out of the frame thereof to be connected with the dust collecting device, and the dust can be easily brushed into the dust dropping holes so as to be collected in the dust collecting device through the dust dropping pipe, therefore the dust can be conveniently cleaned. The dust collecting device can either be a dust collecting box, adust collecting bag or other containers. And in addition, a brush can be mounted at the two ends of the movable board surface, so as to brush the chalk dust from the track groove into the dust dropping hole at the tail end thereof, thereby realizing the self-cleaning function thereof.

Description

Combined type blackboard with chalk dust gathering-device

Technical field

The utility model relates to a kind of teaching aid, especially relates to a kind of push-and-pull combined type blackboard that can conveniently collect chalk dust.

Background technology

Because the combined type blackboard has in finite length expansion write area and push-and-pull characteristics easily, so more and more adopted by education, scientific research institution, enterprise's meeting, training place etc., in order move left and right all can on the housing lower frame, to be provided with moving track, the ash that falls that ash and blackboard wiping caused generally all can focus in this rail groove because the chalk that four bandings close so write on the plate face falls, and is difficult to remove.

Summary of the invention

For solving above-mentioned deficiency of the prior art, the utility model aims to provide a kind of chalk dust gathering-device that has, the combined type blackboard with chalk dust gathering-device of the collection of energy simple and convenient, removing chalk dust.

For achieving the above object, the technical solution of the utility model is such: it comprises blackboard housing, fixed head face A, fixed head face B, portable plate face and collection apparatus for ash etc., wherein frame is provided with the rail groove that moves for the portable plate face under the blackboard housing, the two ends of rail groove respectively are provided with an ash-falling hole vertically downward, be provided with an ash tube in the hole, the ash tube lower end is stretched out frame and is used for outward linking to each other with the rally device, dust can sweep the aerial process of ash ash tube easily and enter gathering-device, is eliminated easily.Described collection apparatus for ash can be that ash collecting box or collection ash bag also can be other container.

In addition, can also a hairbrush be installed respectively at portable plate face two ends, in the process of push-and-pull, the chalk dust in the rail groove be swept in the terminal ash-falling hole, the self-cleaning function in the middle of realizing using by brush.

Take just to realize behind the utility model to collect easily beneficial effect with dust out.

Concrete structure of the present utility model and function will be described with reference to the accompanying drawings by embodiment.

Among the figure: 1, fixed head face A; 2, portable plate face; 3, fixed head face B; 4, blackboard housing; 5, ash tube; 6, collection apparatus for ash; 7, ash-falling hole 8, hairbrush.

The specific embodiment

Referring to Fig. 1, shown in Figure 2, fixed head face A (1) and fixed head face B (3) are the fixed head face among the figure, they and portable plate face (2) that can move left and right have constituted the plate face portion of blackboard jointly, surround blackboard housing (4) around them, on blackboard housing lower frame, be provided with the rail groove that moves for portable plate face (2), all have ash-falling hole (7) downward vertically at the two ends, the left and right sides of rail groove, be inserted with an ash tube (5) in the ash-falling hole (7), this ash tube (5) lower end protrudes in outside the blackboard plate body, and is slotting to block at ash tube (5) ledge and collection apparatus for ash (6), mode such as tying up can easily be connected.Can dust directly be swept ash-falling hole (7) with rag etc. and fall in the collection apparatus for ash (6) and empty easily then when rail groove declines when dust is arranged.

Referring to Fig. 3, figure is another exemplary embodiments of the utility model, difference is that the bipod lower end of portable plate face (2) is equipped with hairbrush (8) among the figure, when can being swept into the dust in the rail groove ash-falling hole (7) at two ends in move left and right the time according to the end in the direction two ends hairbrush (8) that move in, portable plate face (2) collects in the collection apparatus for ash (6) self-cleaning purpose in the middle of realizing using.

Because the utility model is simple in structure, convenient and practical, does not damage overall appearance again, so can solve the deficiencies in the prior art.

Obviously; foregoing is just in order to illustrate characteristics of the present utility model; and be not to restriction of the present utility model, the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the utility model should belong to protection category of the present utility model.
