Description
Technical field
The utility model belongs to teaching aid technical field, specifically, and particularly a kind of hand-held portable chalk dust ledge cleaning plant.
Background technology
Blackboard plays a part very important in teaching practice, applies very extensive.At present, in order to solve the problem of the remaining chalk end of cleaning chalk dust and use, a chalk dust ledge consistent with blackboard length is set mostly under blackboard, in the time that people write on blackboard or after writing, chalk end and used up chalk dust directly fall in this groove, and then sweep with burnisher, though this setting has solved the problem of cleaning chalk end and chalk dust to a certain extent, but be difficult to thoroughly cleaning, and scale removal process is more loaded down with trivial details.
For this reason, there is people that a cleaning slide block is set in chalk dust ledge, clear up chalk end and chalk dust by the slip of cleaning slide block.But in the process of sliding at cleaning slide block, chalk end is easy to be stuck in the gap between slide block and cell wall, thereby having hindered slide block continues to push ahead, need to end cleaning work, the chalk end of jam is taken out and just can be proceeded, so on the one hand complex operation, inconvenience; On the other hand, the efficiency of cleaning is low, and the effect of cleaning is also undesirable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy to operate hand-held portable chalk dust ledge cleaning plant.
The technical solution of the utility model is as follows: a kind of hand-held portable chalk dust ledge cleaning plant, comprise notch cell body (1) upward, one end of described cell body (1) is sealed by baffle plate (5), the other end of cell body (1) is uncovered, and be provided with ash bucket (6) in the uncovered below of this end of cell body (1), the outline of described ash bucket (6) is up big and down small tetragonous cone table, the one end at this ash bucket (6) top articulates mutually with cell body (1), and the other end at ash bucket (6) top is equipped with convertible handle; Slide block (2) is housed in described cell body (1), the centre position at this slide block (2) top is provided with handle (3), front portion and middle part in slide block (2) bottom are all fixed with row brush (8), the rear portion of slide block (2) bottom is fixed with sponge (7), and be provided with push pedal (4) at described slide block (2) towards one end of ash bucket (6), this push pedal (4) is arcuate structure, and arc top and the end of slide block (2) of push pedal (4) fix.
Adopt above technical scheme, when needs are cleared up chalk dust and chalk end, catch handle that slider top arranges firmly with hand, slide block is advanced to one end that ash bucket is installed, and in progradation, push pedal is drawn chalk end together in, and promote the direction motion of chalk end towards ash bucket, gap between push pedal and cell body is less, can prevent that chalk end is stuck in the gap between slide block and cell wall, thereby guarantee the smoothness of scale removal process.The most of chalk dusts that retain in groove are also promoted by push pedal, the row brush brushing that remaining chalk dust is first arranged by slider bottom is clean, and then carry out wiping again and adsorb clean by sponge, when slide block movement is to ash bucket when top, chalk end and chalk dust are fallen in ash bucket under the effect of gravity, are collected by ash bucket.As can be seen here, the utility model is not only time saving and energy saving, and uses very convenient, fastly, and the efficiency of cleaning is high, effective.Ash bucket is tetragonous cone table, and articulates mutually with cell body, and self structure is simple on the one hand, is easy to processing and fabricating, and production cost is low; On the other hand, ash bucket and cell body are easy to connect, and dismounting is very quick, are conducive to topple over fast chalk dust and the chalk end of collection; Meanwhile, convertible handle is installed on ash bucket, can convenient operation and mobile ash bucket.
Described slide block (2) is rectangle hollow structure, and slide block (2) and push pedal (4) are by injection mo(u)lding.Processing and fabricating is easy on the one hand, cost is low for above structure; On the other hand, slide block is good together with the structural strength of push pedal, not yielding or damage.Meanwhile, slide block is comparatively light and handy, operates more laborsaving.
In order to ensure to be connected firmly, to be convenient to processing and fabricating between handle and slide block, described handle (3) is structure as a whole with slide block (2).
For the ease of cleaning and processing and fabricating, two row brushes (8) and the sponge (7) of slide block (2) bottom are equally spaced.
For the ease of processing and fabricating, described sponge (7) is by being adhesively fixed on the bottom of slide block (2).
Beneficial effect: the utility model can be cleared up the chalk dust and the chalk end that drop in chalk dust ledge easily and quickly, has the features such as novel, simple in structure, processing ease.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of slide block and push pedal.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the cell body 1 of chalk dust ledge is positioned at the below of blackboard, and along left and right directions extend, the notch of this cell body 1 upward so that accept chalk dust and chalk end.Described cell body 1 right-hand member is as shown sealed by baffle plate 5, the left end of cell body 1 is uncovered, and cell body 1 left end uncovered below be provided with ash bucket 6, described in this, the outline of ash bucket 6 is up big and down small tetragonous cone table, the one end at these ash bucket 6 tops articulates mutually with cell body 1, and the other end at ash bucket 6 tops is equipped with convertible handle.In described cell body 1, slide block 2 is housed, described slide block 2 is rectangle hollow structure, and the centre position at these slide block 2 tops is provided with handle 3, and described handle 3 is structure as a whole with slide block 2.Front portion and middle part in slide block 2 bottoms are all fixed with row brush 8, and the rear portion of slide block 2 bottoms is provided with sponge 7, and described sponge 7 is by being adhesively fixed on the bottom of slide block 2, and two row brushes 8 and the sponge 7 of described slide block 2 bottoms are equally spaced.Be provided with push pedal 4 at the left end of described slide block 2, described slide block 2 and push pedal 4 are by injection mo(u)lding, this push pedal 4 is arcuate structure, arc top and the left part of slide block 2 of push pedal 4 are fixedly linked, between cell wall corresponding to the rear and front end of described push pedal 4 and cell body 1, there is the gap of 2-5mm, between the bottom of push pedal 4 and the interior diapire of cell body 1, there is the gap of 1-3mm.
Operation principle of the present utility model is as follows:
When needs are cleared up chalk dust and chalk end, catch the handle 3 that slide block 2 tops arrange to exert oneself with hand, slide block 2 is advanced left, in progradation, push pedal 4 is drawn chalk end together in, and promotes the direction motion of chalk end 4 towards ash bucket 6; Simultaneously, the most of chalk dusts that retain in groove are also promoted by push pedal 4, remaining chalk dust is carried out wiping and is adsorbed clean by row brush 8 and the sponge 7 of slide block 2 bottoms, in the time that slide block 2 moves to ash bucket 6 top, chalk end and chalk dust are fallen in ash bucket 6 under the effect of gravity, are collected by ash bucket 6.
