Abstract

The utility model discloses a quick blackboard eraser of hand -pulling type, including clearing cloth and slider, on the slide rail on upper and lower both ends sliding connection both sides limit about the blackboard of slider, and the surface coating of slider has clearing cloth, clearing cloth contact blackboard. This practicality sets up on the blackboard through sliding the slider for the blackboard eraser body that slider and clearing cloth constitute can realize cleaning fast the function of blackboard, coordinates guide pulley A, guide pulley B and stay cord simultaneously, make the slider to make a round trip spurred through the stay cord, thereby make things convenient for cleaning of blackboard, and can so that black people's principle blackboard of board avoid sucking a large amount of chalk dusts, safer.

Description

A kind of hand pulling type fast blackboard eraser

Technical field

This utility model relates to a kind of blackboard eraser, specifically a kind of hand pulling type fast blackboard eraser.

Background technology

Blackboard eraser is a kind of instrument of writing on blackboard wiping, and universal is used for every field. At present, conventional blackboard eraser substantially has brush type and two kinds of forms of felt type, all uses sliding friction former Reason removes blackboard chalk writing.The material such as hairbrush, felt has preferable adsorption to dust, works as hairbrush When type or felt type blackboard eraser surface ratio are cleaner, it has preferable wiping effect, is not easy to produce powder Dirt.

But traditional blackboard eraser is all independent and outside blackboard, in order to blackboard wiping, Zhi Nengyong Hand-held holding the in-plant blackboard wiping of blackboard eraser, not only wiping speed is slow, and distance closely can make user Suck substantial amounts of chalk dust.

Utility model content

The purpose of this utility model is to provide a kind of hand pulling type fast blackboard eraser, to solve above-mentioned background skill The problem proposed in art.

For achieving the above object, the following technical scheme of this utility model offer:

A kind of hand pulling type fast blackboard eraser, including wiper and sliding part, the two ends up and down of described sliding part are sliding Be automatically connected on the slide rail of the upper and lower dual-side of blackboard, and sliding part be coated with wiper, wiper contacts Blackboard.

As further program of the utility model: described wiper is connected by VELCRO head and the tail.

As further program of the utility model: arrange guide wheel A on four angles of described blackboard, blackboard is left Right both sides arrange guide wheel B, and the two ends up and down of sliding part are all fixed with two stay cords, and wherein a stay cord depends on The secondary guide wheel A through blackboard side, annulus and guide wheel B, collected the stay cord at upper and lower two ends by annulus； Another root stay cord sequentially passes through the guide wheel A of blackboard opposite side, annulus and guide wheel B so that sliding part can be by Pull back and forth.

As further program of the utility model: the bottom of described blackboard arranges ash collection slot.

Compared with prior art, the beneficial effects of the utility model are: by being slidably arranged in by sliding part On blackboard so that the blackboard eraser body that sliding part and wiper are constituted is capable of the function of quick wipe blackboard, Coordinate guide wheel A, guide wheel B and stay cord so that sliding part can be pulled back and forth by stay cord simultaneously, thus The wiping of Convenient blackboard, and so that people's principle blackboard of erasing the board, it is to avoid suck substantial amounts of chalk dust, Safer.

Accompanying drawing explanation

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

In figure: blackboard 1, stay cord 2, wiper 3, sliding part 4, guide wheel A5, guide wheel B6, annulus 7, collection ash Groove 8.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this The scope of utility model protection.

Refer to Fig. 1, in this utility model embodiment, a kind of hand pulling type fast blackboard eraser, including stay cord 2, Wiper 3, sliding part 4, guide wheel A5, guide wheel B6 and annulus 7, the two ends up and down of described sliding part 4 are sliding It is automatically connected on the slide rail of blackboard about 1 dual-side, thus ensures that sliding part 4 can be on the surface of blackboard Slidably reciprocate, and then ensure the function of writing on erasing blackboard, and sliding part 4 be coated with wiper 3, Contact blackboard-cleaning by wiper 3, while not injuring blackboard, ensure that blackboard can be wiped by wiped clean Cloth 3 is connected by VELCRO head and the tail, in order to disassemble cleaning.

Described guide wheel A5 is arranged on four angles of blackboard 1, and guide wheel B6 is arranged on blackboard 1 left and right sides, And the two ends up and down of sliding part 4 are all fixed with two stay cords 2, wherein a stay cord 2 sequentially passes through blackboard 1 The guide wheel A5 of side, annulus 7 and guide wheel B6, collected the stay cord 2 at upper and lower two ends, so by annulus 7 Afterwards by pulling the stay cord after collecting 2 can realize the slip of sliding part 4；Another root described sequentially passes through The guide wheel A5 of blackboard 1 opposite side, annulus 7 and guide wheel B6 so that sliding part 4 can be pulled back and forth, And then blackboard wiping, utilize the spy of movable pulley to use, it is ensured that the stay cord 2 on guide wheel B6 can be arbitrarily Angle pulls.

The bottom of described blackboard 1 arranges ash collection slot 8, it is simple to collect dust.

Operation principle of the present utility model is: by being slidably arranged on blackboard 1 by sliding part 4 so that The blackboard eraser body that sliding part 4 and wiper 3 are constituted is capable of the function of quick wipe blackboard, joins simultaneously Close guide wheel A5, guide wheel B6 and stay cord 2 so that sliding part 4 can be pulled back and forth by stay cord 2, from And the wiping of Convenient blackboard, and so that people's principle blackboard of erasing the board, it is to avoid suck substantial amounts of chalk Ash, safer.

It is obvious to a person skilled in the art that this utility model is not limited to above-mentioned one exemplary embodiment Details, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to other Concrete form realizes this utility model.Which point therefore, no matter from the point of view of, embodiment all should be regarded as Exemplary, and be nonrestrictive, scope of the present utility model by claims rather than on State bright restriction, it is intended that all changes that will fall in the implication of equivalency and scope of claim Change and include in this utility model.Any reference in claim should be considered as restriction involved Claim.

Moreover, it will be appreciated that although this specification is been described by according to embodiment, but the most each reality Mode of executing only comprises an independent technical scheme, and this narrating mode of description is only for understand Seeing, those skilled in the art should be using description as an entirety, and the technical scheme in each embodiment is also Other embodiments that it will be appreciated by those skilled in the art that can be formed through appropriately combined.
