Embodiment
The invention will be further described with reference to the accompanying drawings and examples, but should not be construed the above-mentioned theme of the present invention
Scope is only limitted to following embodiments.Without departing from the idea case in the present invention described above, known 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, referring to Fig. 1 to Fig. 4, including lower house 1, upper shell 2, disposable box 3,
Roller brush 4, gear 5, rack 6, movable block 7, spring 8 and blackboard eraser 9.
The lower house 1 and disposable box 3 are the open rectangular box in upper end.The disposable box 3 is placed on lower house 1
It is interior.The side wall of the lower house 1 is provided with an opening for being put into/extracting out for disposable box 3.The top both sides of the lower house 1
Respectively there is a chute 10 slided for upper shell 2.
The upper shell 2 is arranged on the upper end of lower house 1, and after installation, upper shell 2 can the front and rear shifting on chute 10
It is dynamic.In order to prevent the displacement of upper shell 2 excessive, cause upper shell 2 departing from lower house 1, so being additionally provided with chute 10
Limiting plate 13.After upper shell 2 moves a certain distance in fore-and-aft direction, then it can be limited plate 13 and block, prevent upper shell 2 from continuing
Continue to move to this side up.
The upper shell 2 is a rectangular box.The all round closure of the upper shell 2, its top have a cover plate
201, bottom is one flat plate 202.The side of the cover plate 201 is connected through the hinge at the top of upper shell 2 so that cover plate
201 raise or close around pin joint.The lower surface of the cover plate 201 has a protruding block, and this protruding block is for depressing black
Blackboard eraser 9.A rectangular-shaped through hole is opened in the center of the flat board 202, and this through hole is used to leak down chalk powder.The flat board 202
On be fixed with two racks 6 and four vertical support bars 203.Distance of the forward and backward both ends of the flat board 202 to center through hole
It is all higher than displacement of the upper shell 2 on chute 10.
The orientation for defining the surrounding of flat board 202 is respectively all around.Two racks 6 are located at the left and right two of flat board 202 respectively
Side, and be parallel to each other with chute 10.The support bar 203 is located at the front and rear sides (front and rear each two) of flat board 202, and every branch
Spring 8 is cased with strut 203.The upper end of the wherein support bar 203 of front and rear sides is connected with a movable block 7 respectively.The activity
The lower end of block 7 is provided with corresponding patchhole so that the upper end of support bar 203 is located in patchhole.The lower end of the spring 8 is with putting down
The plate face contact of plate 202, its upper end contacts with the lower surface of movable block 7.When spring 8 is compressed, movable block 7 is in support bar
Moved down on 203.
There is a gear 5 being engaged respectively on two racks 6.Two gears 5 are connected by a horizontal rotating shaft 11.
The upper sleeve through of rotating shaft 11 has roller brush 4.The roller brush 4 is located at the surface of the through hole of flat board 202.The rotating shaft 11
On be provided with the limiting card 12 being arranged symmetrically, the strong point of the limiting card 12 is located in lower house 1.The limiting card 12 due to
It is the element propped from lower house 1, and is fixed, so limiting card 12 limits moving horizontally for rotating shaft 11 so that rotating shaft
11 can only rotate.Specifically, rotating shaft 11 be by bearings on limiting card 12.
During work, the blackboard eraser 9 (referring to Fig. 2, blackboard eraser 9 is general blackboard eraser, is made up of rectangle plate face and hair side)
Both ends are respectively supported on the movable block 7 of front and rear sides, and hair side is downward, close cover plate 201, and now protruding block will push black
Blackboard eraser causes it to move down, and the hair side that the height of projection of protruding block is just met for pushing rear blackboard eraser 9 connects with roller brush 4
Touch, then promote upper shell 2 movable along chute 10 manually, so as to drive roller brush 4 to be rotated in defined position.Herein
The horizontal displacement of process middle gear 5 and rotating shaft 11 is defined, so the moving belt carry-over bar 6 of upper shell 2 moves, so as to
Gear 6 and rotating shaft 11 rotate, and roller brush 4 is worked, while blackboard eraser 9 is also in movable state, so as to complete
The dust of the whole hair side of clear all.
After the completion of cleaning, cover plate 201 is opened, jacks up movable block 7 automatically in the presence of spring 8, so as to which blackboard eraser 9 is upward
It is mobile to can be taken off, while extract disposable box 3 out, the dust of the inside is put into specified collection site.
