Abstract

The utility model discloses a blackboard eraser dust shaking device which comprises a box, a brush, a first reciprocating mechanism, a second reciprocating mechanism and a power source. An opening capable of supporting the edge of a blackboard eraser from the position below the blackboard eraser is formed above the box, and is matched with the edge of the blackboard eraser, an open-closed base plate is arranged at the bottom of the box, the brush is used for brushing chalk dust on the blackboard eraser, the first reciprocating mechanism can reciprocate in the mode of being parallel to the short edges of the blackboard eraser, and is in transmission connection with the brush, the second reciprocating mechanism can reciprocate in the mode of being parallel to the long edges of the blackboard eraser, and is in transmission connection with the first reciprocating mechanism, the power source is connected with the first reciprocating mechanism and the second reciprocating mechanism, and a switch of the power source is arranged on the outer surface of the box. According to the blackboard eraser dust shaking device, the brush is matched with the first reciprocating mechanism and the second reciprocating mechanism to be capable of automatically and overall remove the chalk dust on the blackboard eraser completely and store the chalk dust into the box, and the human body is prevented from being harmed by the fact that the chalk dust rises around.

Description

Blackboard eraser is trembled powder device

Technical field

The utility model belongs to office stationary field, relates in particular to a kind of blackboard eraser and trembles powder device.

Background technology

Blackboard eraser is the instrument of wiping chalk trace in black and white, and what it was general is applied to school.

In the time that accumulation on blackboard eraser has a large amount of chalk dust, conventionally remove the chalk dust on it by artificial mode, as modes such as mouth blows, beatings, this manual mode dust removing effects is not good, while reusing, what can make that blackboard becomes is dirtier, and manual mode causes chalk dust to fly upward everywhere, harmful to health.

Utility model content

Based on this, for above-mentioned technical problem, provide a kind of blackboard eraser to tremble powder device.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of blackboard eraser is trembled powder device, comprising:

Box body, the top of described box body have can be from supported underneath blackboard eraser edge uncovered, this uncovered and described blackboard eraser edge adaptation, the bottom of described box body has base plate that can folding;

For brushing the brush of the chalk dust on blackboard eraser;

Can be parallel to the first reciprocator that the minor face of blackboard eraser moves reciprocatingly, this first reciprocator and described brush are in transmission connection;

Can be parallel to the second reciprocator that the long limit of blackboard eraser moves reciprocatingly, this second reciprocator and described the first reciprocator are in transmission connection;

Power supply, described power supply is connected with described the first reciprocator and the second reciprocator, and the switch of this power supply is located at the outer surface of described box body.

Described uncovered both sides are all hinged with hasp.

Described the first reciprocator and the second reciprocator are cylinder, and described the first reciprocator is fixed on the piston rod of described the second reciprocator, and described brush is fixed on the piston rod of described the first reciprocator.

The utility model is simple in structure, easy to use, brush of the present utility model coordinates the first reciprocator and the second reciprocator automatically comprehensively the chalk dust on blackboard eraser to be cleaned out, and chalk dust is accommodated in box body, has avoided flying upward human body being worked the mischief everywhere because of chalk dust.

Accompanying drawing explanation

Be elaborated below in conjunction with the drawings and specific embodiments the utility model:

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

The specific embodiment

As shown in Figure 1, a kind of blackboard eraser is trembled powder device, comprises box body 110, brush 120, the first reciprocator 130, the second reciprocator 140 and power supply.

The top of box body 110 have can be from supported underneath blackboard eraser edge uncovered 111, this uncovered 111 with blackboard eraser edge adaptation, for placing blackboard eraser.

Be understandable that, for blackboard eraser being fixed on to uncovered 111 places, uncovered 111 both sides are all hinged with hasp.

The bottom of box body 110 has base plate that can folding, is convenient to clear up the chalk dust on base plate.

Brush 120 is for brushing the chalk dust on blackboard eraser.

The minor face that the first reciprocator 130 can be parallel to blackboard eraser moves reciprocatingly, and itself and brush 120 are in transmission connection, and the minor face that can drive brush 120 to be parallel to blackboard eraser is back and forth shaken, the chalk dust thereby brush falls.

The long limit that the second reciprocator 140 can be parallel to blackboard eraser moves reciprocatingly, and itself and the first reciprocator 130 are in transmission connection, and move on the long limit that can drive brush 120 to be parallel to blackboard eraser, thereby whole blackboard eraser can both be brushed.

Power supply is connected with the first reciprocator 130 and the second reciprocator 140, and for above-mentioned Liang Ge mechanism provides power supply, and the switch of this power supply is located at the outer surface of box body 110.

Particularly, the first reciprocator 130 and the second reciprocator 140 are cylinder, and the first reciprocator 130 is fixed on the piston rod of the second reciprocator 140, and brush is fixed on the piston rod of the first reciprocator 130.

Certainly, the first reciprocator 130 and the second reciprocator 140 also can adopt other form.

But, those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, and be not used as restriction of the present utility model, as long as within the scope of connotation of the present utility model, variation, modification to the above embodiment all will drop within the scope of claims of the present utility model.
