Abstract
The invention provides a dust-removal blackboard eraser. The dust-removal blackboard eraser comprises a lower shell body, an upper shell body, a collecting box, a roller hairbrush, gears, racks, movable blocks, springs and a blackboard eraser body. According to the main work principle, the linear movement of the upper shell body is transferred to the gears and the racks, the gears are driven to move linearly, meanwhile, the horizontal movement of the gears is limited, and thus the gears rotate. The roller hairbrush rolls when making contact with the blackboard eraser body, and dust on the hairy surface of the blackboard easer is effectively cleaned up. According to the dust-removal blackboard eraser, dust on the blackboard easer can be effectively removed and does not pollute the environment air, and the health of workers is facilitated. In addition, the dust waste is recycled to become the valuable, so that resources are saved.

Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings, but should not
It is interpreted as that the above-mentioned subject area of the present invention is only limitted to following embodiment.Without departing from the present invention
In the case of stating technological thought, according to ordinary skill knowledge and customary means, make
Various replacements and change, all should include within the scope of the present invention.
The present embodiment provides a kind of dust-removing blackboard eraser, sees Fig. 1 to Fig. 4, including lower house 1,
Upper shell 2, disposable box 3, roller brush 4, gear 5, tooth bar 6, movable block 7, spring
8 and blackboard eraser 9.
Described lower house 1 and disposable box 3 are the rectangular box that upper end is uncovered.Described collection
Box 3 is placed in lower house 1.The sidewall of described shell body 1 is provided with one for disposable box 3
The opening put into/extract out.The both sides, top of described lower house 1 respectively have one for upper shell 2
The chute 10 slided.
Described upper shell 2 is arranged on the upper end of lower house 1, after installation, and upper shell 2
Can move forward and backward on chute 10.In order to prevent upper shell 2 displacement excessive, cause
Upper shell 2 is departing from lower house 1, so being additionally provided with limiting plate 13 on chute 10.When upper
Housing 2 after fore-and-aft direction moves a certain distance, then can block, in prevention by limited plate 13
Housing 2 continues to continue to move to this side up.
Described upper shell 2 is a rectangular box.The all round closure of described upper shell 2, its
Top has a cover plate 201, and bottom is one flat plate 202.The side of described cover plate 201
It is connected through the hinge at the top of upper shell 2 so that cover plate 201 is raised around pin joint or closes
On.The lower surface of described cover plate 201 has a protruding block, this protruding block for depressing
Blackboard eraser 9.The central authorities of described flat board 202 open a rectangular-shaped through hole, and this through hole is used for
Leak down chalk powder.Two tooth bars 6 and four vertical supports it are fixed with on described flat board 202
Bar 203.The forward and backward two ends of described flat board 202 are all higher than upper shell to the distance of center through hole
2 displacements on chute 10.
The orientation of definition flat board 202 surrounding is respectively all around.Two tooth bar 6 positions respectively
In the left and right sides of flat board 202, and it is parallel to each other with chute 10.Described support bar 203
Both sides (the most each two) before and after flat board 202, and it is cased with bullet on every support bar 203
Spring 8.Before and after wherein, the upper end of the support bar 203 of both sides is connected with a movable block 7 respectively.Institute
The lower end stating movable block 7 has the insertion hole of correspondence so that the upper end of support bar 203 is positioned at
In insertion hole.The lower end of described spring 8 contacts with the plate face of flat board 202, its upper end and work
The lower surface contact of motion block 7.When spring 8 is compressed, movable block 7 is at support bar 203
On move down.
A gear matched 5 it is respectively provided with on two tooth bars 6.Two gears 5 are by one
Root horizontal rotating shaft 11 connects.Described rotating shaft 11 upper sleeve through has roller brush 4.Described cylinder hair
Brush 4 is positioned at the surface of the through hole of flat board 202.It is provided with in described rotating shaft 11 and is arranged symmetrically with
Limiting card 12, the strong point of described limiting card 12 is positioned at lower house 1.Described limiting card
12 owing to being the element propped from lower house 1, and is fixed, so limiting card 12 limits
The moving horizontally of rotating shaft 11 so that rotating shaft 11 can only rotate.Specifically, turn
Axle 11 by bearings on limiting card 12.
During work, (seeing Fig. 2, blackboard eraser 9 is general blackboard eraser to described blackboard eraser 9, by square
Shape plate face and hair side composition) two ends be respectively supported on the movable block 7 of before and after both sides, and
Hair side is downward, and close cover plate 201, and now protruding block will press down blackboard eraser to make it to moving down
Dynamic, the height of projection of protruding block be just met for down pressing after blackboard eraser 9 hair side with roll hairbrush 4
Contact, the most manually promotes upper shell 2 to move forward and backward along chute 10, thus drives rolling hair
Brush 4 rotates in defined position.The horizontal displacement of gear 5 and rotating shaft 11 is in the process
It has been defined, so the mobile band carry-over bar 6 of upper shell 2 moves, thus gear 6 He
Rotating shaft 11 rotates, and makes rolling hairbrush 4 work, and blackboard eraser 9 is also in moving forward and backward simultaneously
State, it is thus possible to be fully apparent from the dust of whole hair side.
After having cleared up, open cover plate 201, automatic jack-up movable block under the effect of spring 8
7, thus blackboard eraser 9 moves up and i.e. can be taken off, and extracts disposable box 3 out, by the inside simultaneously
Dust puts into appointment collection site.
