Abstract

The utility model provides a blackboard eraser which structurally comprises a board body, a magnet and a scrubbing body, wherein the board body is provided with an upper surface, a lower surface, a front surface and a rear surface; a mounting opening penetrating through the upper surface and the lower surface is formed in the middle of the board body; the magnet is fixedly arranged on the lower surface of the board body; a fixing block is arranged on the scrubbing body in a protruding manner; the fixing block is fixedly mounted in the mounting opening; mounting grooves are formed on the front surface and the rear surface of the board body; and scrubbing blocks are arranged in the mounting grooves. Since the blackboard eraser is provided with the magnet, hand feeling during the use can be enhanced; and compared with a common blackboard eraser, the blackboard eraser provided by the utility model has the advantages that the weight is increased, so that a user is enabled to effectively scrub the effect of characters on a blackboard quickly, and in virtue of the magnet, dust can be adsorbed, and the effect of dust flying can be prevented.

Description

A kind of blackboard eraser

Technical field

The utility model relates to a kind of scrubber, more specifically is meant a kind of blackboard eraser.

Background technology

For a long time, the letter written with chalk on the blackboard is often wiped unclean, mainly is the problem of blackboard eraser, general blackboard eraser is gathering many chalk dusts on its fine hair after the use, be difficult to its removing, even wipe muddledly more more, and chalk dust flies upward everywhere when erasing the board, cause environmental pollution, in addition, common blackboard eraser is to adopt cloth to be entwined, and weight is lighter, carry though made things convenient for using, in the process of cleaning, need to apply excessive pressure.

Summary of the invention

Main purpose of the present utility model be to provide a kind of manufacturing simple, prevent that dust from flying upward, cleaning letter written with chalk blackboard eraser easily.

The technical solution adopted in the utility model is: a kind of blackboard eraser, comprise plate body, magnet and scrub body, wherein, this plate body has upper surface, lower surface, front surface and rear surface, the middle part of this plate body offers the installing port that runs through its upper surface and lower surface, this magnet is fixedly installed on the lower surface of this plate body, this is done the wash body and convexes with a fixed block, this fixed block is fixedly mounted in this installing port, the front surface of this plate body and rear surface all offer mounting groove, and all are provided with in this mounting groove and scrub piece.

This scrubs piece and this, and to do the wash body be sponge.

The beneficial effects of the utility model are: the utility model structurally comprises, plate body, magnet and scrub body, wherein, this plate body has upper surface, lower surface, front surface and rear surface, the middle part of this plate body offers the installing port that runs through its upper surface and lower surface, this magnet is fixedly installed on the lower surface of this plate body, this is done the wash body and convexes with a fixed block, this fixed block is fixedly mounted in this installing port, the front surface of this plate body and rear surface all offer mounting groove, and all are provided with in this mounting groove and scrub piece.By its special structure design,, can increase the feel when using owing to the utlity model has magnet, compare the normal blackboard brush and increased weight, can make the user fast, effectively clean the effect of the font in the blackboard, and have, prevent the effect that dust flies upward by magnet absorption dust.

The specific embodiment

Be a kind of preferable specific embodiment of the present utility model as shown in Figure 1 to Figure 3, a kind of blackboard eraser, comprise plate body 10, magnet 20 and scrub body 30, wherein, this plate body 10 has upper surface 11, lower surface 12, front surface 13 and rear surface 14, the middle part of this plate body 10 offers the installing port 15 that runs through its upper surface 11 and lower surface 12, this magnet 20 is fixedly installed on the lower surface 11 of this plate body 10, this is done the wash body 30 and convexes with a fixed block 31, and this fixed block 31 is fixedly mounted in this installing port 15.

Further, the front surface of this plate body 10 13 all offers mounting groove 16 with rear surface 14, and all is provided with in this mounting groove 16 and scrubs piece 17.

Further, this is scrubbed piece 17 and does the wash body 30 with this and be sponge or bristle.

What the utility model will be realized is in concrete practicality, can utilize the body of scrubbing of the present utility model to clean blackboard, and in the process of scrubbing, magnet 20 of the present utility model can to adsorb dust, is unlikely to make dust to fly upward everywhere.

The more important thing is, owing to the utlity model has magnet, can increase the feel when using, comparing the normal blackboard brush has increased weight, can make the user fast, effectively clean font in the blackboard.

Also what deserves to be mentioned is,, in actual use, can make things convenient for the user to clean interior among a small circle font, go to clean and be unlikely to use finger because forward and backward surface of the present utility model all is provided with and scrubs piece.

In addition, because the utility model is simple in structure, therefore has advantage easy to make.

Embodiment of the present utility model and accompanying drawing are just in order to show design concept of the present utility model, and protection domain of the present utility model should not be confined to this embodiment.

Can effectively implement by top narration purpose of design of the present utility model as can be seen.The part of embodiment has been showed the purpose of this utility model and has been implemented function and structural themes, and comprised other the replacement that is equal to.

Therefore, right of the present utility model constitutes the equivalence that comprises other to be implemented, and the concrete right scope is with reference to claim.

Claims
