The utility model discloses a roll-like black-board eraser with chalk-dust collection. A chalk baffle plate is fixedly connected with a shell body, and then a sealed hollow cavity is formed to accommodate chalk dust. A chalk scraping plate is fixed on the shell body. Chalk rubbing material is pasted on a cylinder. A chalk discharge opening is a hole arranged on the end of the shell body. The chalk baffle plate is fixedly connected with the shell body. The chalk scraping plate is fixedly connected with the shell body. Short shafts exposed out of both ends of the cylinder are inserted on the hole of the shell body. The utility model uses the black-board eraser with cylinder type movement to replace the existing place type fixed black-board eraser. The utility model has the characteristics that the chalk rubbing material is pasted on the cylinder to continuously work, the function is strong compared with the existing black-board eraser, the structure is simple, and the use is convenient.
Description
The utility model relates to a kind of drum-type blackboard eraser of collecting powder.Exactly, it is exactly that a kind of novel chalk that is used on the blackboard for education is wiped.
Existing blackboard eraser after a period of time of nuzzling up, is wiped chalk dust down and just is difficult for attached to top, but along with the wiping of blackboard eraser is moved and arbitrarily descended slowly and lightly.For addressing this problem,
The purpose of this utility model is to design a kind of novel drum-type blackboard eraser.
For this reason, the utility model has designed a kind of drum-type blackboard eraser of collecting powder, its powder blocking plate and housing connect firmly, form sealed hollow and hold powder, powder-wiping plate is fixed on the housing, and the crocus material sticks on the cylinder, powder outlet is the hole on the shell end, powder blocking plate and housing connect firmly, and powder-wiping plate and housing connect firmly, and the minor axis that expose at the cylinder two ends inserts in the hole on the housing.
The utility model replaces existing plane fixing blackboard eraser with the blackboard eraser of drum-type activity, and its maximum characteristics are exactly that its crocus material sticks on the cylinder, can continuous operation.Powder-wiping plate can prevent that cylinder from skidding, and can constantly scrape the chalk dust that sticks on the crocus material, keeps the cleaning of cylinder.Have than strong, simple in structure, the easy to use characteristics of original blackboard eraser function.
The utility model will be further described below with reference to accompanying drawing:
Fig. 1 is a front view of the present utility model
Fig. 2 is a left pseudosection of the present utility model
Among the figure, 1 is housing; 2 is powder outlet; 3 is powder blocking plate; 4 is powder-wiping plate; 5 is cylinder; 6 is the crocus material; 7 is blackboard
As we know from the figure, housing 1 is used to accommodate powder, also is the position of handing, powder outlet 2 is used for the powder of collecting in the housing is poured out, powder blocking plate 3 connects firmly with housing, forms sealed hollow and holds powder, and powder-wiping plate 4 is fixed on the housing, be used for the chalk dust of cylinder surface absorption is scraped in the housing 1, crocus material 6 sticks on the cylinder, and crocus material 6 can or be a sponge etc. with felt, when blackboard eraser during in blackboard 7 side-to-side movements, ash under inhaling can in time be scraped by powder-wiping plate 4, and leaves in the housing 1.The cleaning that can keep cylinder 5 like this makes it to remain on the state of good easy absorption chalk dust always.When the quantity of chalk dust acquires a certain degree, lid can be opened, pour out chalk dust from powder outlet 2.Powder outlet 2 is the holes on housing 1 end, and powder blocking plate 3 connects firmly with housing 1, and powder-wiping plate 4 connects firmly with housing, and the minor axis that expose at cylinder 5 two ends inserts in the hole on the housing 1, makes cylinder 5 location and can rotate in the hole on housing, and crocus material 6 sticks on the cylinder.
Blackboard eraser with the drum-type activity replaces existing plane fixing blackboard eraser, and its maximum characteristics are exactly that its crocus material sticks on the cylinder, can continuous operation.Powder-wiping plate 4 can prevent that cylinder 5 from skidding, and can constantly scrape the chalk dust that sticks on the crocus material 6, keeps the cleaning of cylinder 5.
