Description

The quick cleaning plant of chalk dust ledge

Technical field

The utility model belongs to teaching aid technical field, specifically, and the particularly quick cleaning plant of a kind of chalk dust ledge.

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, when 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, by the slip of cleaning slide block, clear up chalk end and chalk dust.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 the quick cleaning plant of chalk dust ledge of a kind of convenient and swift cleaning chalk dust and chalk end.

The technical solution of the utility model is as follows: the quick cleaning plant of a kind of chalk dust ledge, 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 being provided with ash bucket (6) in the uncovered below of this end of cell body (1), this ash bucket (6) articulates mutually with cell body (1); Slide block (2) is housed in described cell body (1), the centre position of this slide block (2) front bulkhead is provided with handle (3), described handle (3) consists of fixed arm (3a) and lever arm (3b), one end of fixed arm (3a) and slide block (2) fix, the other end of fixed arm (3a) stretches out forward outside cell body (1), and hinged with lever arm (3b), lever arm (3b) can be in 90 ° of upsets of above-below direction; The hole (8) that described cell body (1) front side wall passes through for fixed arm (3a) is strip hole, the fixing sponge (7) in the bottom of described slide block (2), and towards one end of ash bucket (6), be provided with push pedal (4) at described slide block (2), this push pedal (4) is arcuate structure, arc top and the end of slide block (2) of push pedal (4) fix, the gap between the cell wall corresponding with cell body (1) of the two ends of described push pedal (4) with 2-5mm, has the gap of 1-3mm between the bottom of push pedal (4) and the interior diapire of cell body (1).

Adopt above technical scheme, when needs are cleared up chalk dust and chalk end, with hand, catch the lever arm of handle to exert oneself, 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 chalk end towards the direction motion of 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, remaining chalk dust is first carried out wiping and is adsorbed clean by the sponge of slider bottom, 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, by ash bucket, are collected.After cleaning work completes, the lever arm of handle upwards can be carried out to 90 ° of upsets, can draw upward lever arm in, in order to avoid stretch out in the lever arm of cell body outer wall, human body is collided and swipe, effectively prevented the injury to human body.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.

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.

For the ease of grasping, on described lever arm (3b), be set with the little gum cover in two broad in the middle.

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 chalk dust and the chalk end dropping in chalk dust ledge easily and quickly, has the features such as novel, simple in structure, processing ease, cost be low, safe and reliable.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the top view of Fig. 1.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As shown in Figure 1 and Figure 2, the utlity model has notch cell body 1 upward, this cell body 1 extends along left and right directions, and is positioned at the below of blackboard, to accept chalk dust and chalk end.The right-hand member of described cell body 1 is sealed by baffle plate 5, and the left end of cell body 1 is uncovered, and cell body 1 left end uncovered below be provided with ash bucket 6, this ash bucket 6 articulates mutually with cell body 1.In described cell body 1, slide block 2 is housed, described slide block 2 is rectangle hollow structure, the centre position of these slide block 2 front bulkheads is provided with handle 3, described handle 3 consists of fixed arm 3a and lever arm 3b, one end of fixed arm 3a and slide block 2 fix, and the other end of fixed arm 3a stretches out forward outside cell body 1, and hinged with lever arm 3b, lever arm 3b can be in 90 ° of upsets of above-below direction, and on lever arm 3b, are set with the little gum cover in two broad in the middle.

As shown in Figure 1 and Figure 2, the hole 8 that described cell body 1 front side wall passes through for fixed arm 3a is strip hole, the left end in this strip hole is near ash bucket 6, and right-hand member arranges sponge 7 near baffle plate 5. in the bottom of described slide block 2, and described sponge 7 is by being adhesively fixed on the bottom of slide block 2.At described slide block 2, towards one end of ash bucket 6, be provided with push pedal 4, described slide block 2 and push pedal 4 are by injection mo(u)lding, this push pedal 4 is arcuate structure, the arc top of push pedal 4 is integrated mutually with the end of slide block 2, the gap between the cell wall corresponding with cell body 1 of the rear and front end of described push pedal 4 with 2-5mm, has the gap of 1-3mm between the bottom of push pedal 4 and the interior diapire of cell body 1.

The utility model operation principle is as follows:

When needs are cleared up chalk dust and chalk end, first make fixed arm 3a and lever arm 3b keep point-blank, then with hand, catch lever arm 3b firmly, slide block 2 is advanced to one end that ash bucket 6 is installed, in progradation, push pedal 4 is drawn chalk end together in, and promotes chalk end 4 towards the direction motion of ash bucket 6; Simultaneously, the most of chalk dusts that retain in groove are also promoted by push pedal 4, and remaining chalk dust is carried out wiping and adsorbed totally by the sponge 7 of slide block 2 bottoms, when 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, by ash bucket 6, are collected.After having cleared up, slide block 2 is got back to low order end, finally upwards pulls lever arm 3b, makes it, with respect to 90 ° of fixed arm 3a upsets, to form folding shape.
