Abstract

The utility model provides a roller brush type dust-collecting blackboard eraser which relates to the technical field of stationery. The roller brush type dust-collecting blackboard eraser is formed by roller brushes, a strip-shaped brush, a power wheel, a gear box, balance wheels and a dust collecting box, wherein the gear box is fixed at the middle part of the dust collecting box and is provided with a swinging wheel groove, and a shaft passes through the middle part of the gear box and is fixedly provided with the power wheel and a driving gear; the driving gear is connected with a swinging gear; and the swinging gear is connected with a driven gear and can move in the swinging wheel groove. Preferably, the driven hear is connected with a guide gear which is connected with a roller brush gear; and the roller brushes are connected with the two sides of a roller brush gear shaft. Compared with the prior art, the roller brush type dust-collecting blackboard eraser disclosed by the utility model has the obvious advantages that dust is collected into a collecting box in a manner that the roller brushes rotate to generate air flow, so that indoor pollution is relieved, and further, the harm of the dust to the health of teachers and students is reduced; and the roller brush type dust-collecting blackboard eraser is convenient to use and serves as one stationery which has a very high popularization value.

Description

The roller-brush type dust absorption blackboard eraser

Technical field

The utility model belongs to a kind of school supply and stationery, is the roller-brush type dust absorption blackboard eraser specifically.

Technical background

In the school of small and medium-sized cities, still at the blackboard eraser that uses old-fashioned plank felt face.This type of blackboard eraser is when erasing the board, and dust flies upward everywhere, causes indoor environmental pollution, and the serious harm teachers and students are healthy.

The utility model content

The purpose of the utility model be to existing blackboard eraser deficiency---in use, dust flies upward everywhere, pollute indoor environment, the serious harm teachers and students are healthy, and a kind of blackboard eraser that can collect dust is provided.

The purpose of the utility model realizes through following technological means: the roller-brush type dust absorption blackboard eraser, to form by roller brush, bar shaped brush, power wheel, gear-box, stabilizer and dust collection box, and gear-box is being fixed at dust collection box middle part; Have the swing race on the gear-box; The gear-box middle part is installed with axle, is fixing power wheel and driving gear on the said axle, and driving gear is connected with wobble gear; Wobble gear is connected with driven gear, and wobble gear can move in the swing race.

As preferably, said driven gear is connected with guide gear, and guide gear is connected with roller brush gear; Roller brush gear shaft both sides are connected with the roller brush.

Compared with prior art the utlity model has following tangible advantage: the mode that produces air-flow through the rotation of roller brush; Dust is sucked in the collection box, reduce indoor pollution, thereby reduce dust the healthy harm of teachers and students; Easy to use, be a kind of school supply and stationery that promotional value is arranged very much.

The specific embodiment

Below in conjunction with description of drawings the utility model is done further to describe in detail:

The use of this roller-brush type dust absorption blackboard eraser is: the writing under the bar shaped brush 4 of roller brush both sides is wiped on the blackboard; Power wheel 1 and black print face friction generates power drive to roller brush 2 through the gear train in the gear-box 5, wherein through wobble gear 7 swinging back and forth in swing race 11; Conversion connects driven gear 8; Thereby roller brush 2 is turned to the inside all the time, produce the air-flow to 12 internal flows of dust collection box, the dust under bar shaped brush 4 is wiped is brought in the dust collection box 12.Stabilizer 3 keeps the angle of blackboard eraser bottom surfaces and blackboard, avoids roller brush 2 to contact with the black print face, and it is littler to make roller brush the resistance of 2 rotations.

In a word, the utility model provides a kind of roller-brush type dust absorption blackboard eraser.The above; Be merely a part of specific embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
