Abstract
Disclosed is a dust collecting blackboard eraser without electric power. A bottom plate, an edging and an erasing felt piece are sequentially placed; the edging is positioned at the edge position on the bottom plate; the inner side of the edging is inclined inwards; the erasing felt piece is positioned at the central position on the bottom plate; and a dust collecting rubber strip inclined inwards is additionally placed on the edging. When the blackboard eraser is pressed on the surface of a blackboard, the dust collecting rubber strip, the bottom plate and the surface of the blackboard form a closed space to function in dust collecting without electric power.
Description
Technical field
The utility model relates to the device of wiping chalk trace on the blackboard, especially unpowered control of dust blackboard eraser.
Background technology
At present, blackboard eraser by base plate, edge strip, wipe the felt piece and form, wipe chalk trace on the blackboard by wiping the felt piece.But, because edge strip can not form the space of sealing with blackboard surface, do not have the effect of control of dust, wipe the dust from flying of falling, on one's body promptly flying easily, the influence image, also easily in the suction body, unhealthful; Though electric dust blackboard eraser energy control of dust uses inconvenience, also consumes energy.
Summary of the invention
Can not control of dust or the deficiency of power consumption in order to overcome existing blackboard eraser, the utility model provides a kind of blackboard eraser, and this blackboard eraser not only can control of dust, and does not need electric power.
The technical scheme that its technical problem that solves the utility model adopts is: base plate, edge strip, wipe the felt piece and place successively, edge strip is positioned at the edge above the base plate, and the edge strip inboard tilts inwards, wipes the felt piece and is positioned at middle position above the base plate; Place a control of dust rubber strip and slope inwardly on edge strip, when blackboard eraser was pressed on the blackboard surface, control of dust rubber strip, base plate, blackboard surface formed enclosure space, play dust agglutination, and need not electric power; The two ends of blackboard eraser are semicircle, make control of dust rubber strip circle suitable, and easy and blackboard surface forms enclosure space; The control of dust rubber strip with wipe the felt piece and leave the space, with the storage dust; The control of dust rubber strip slopes inwardly, and dust can not expose when blackboard eraser left the blackboard surface; The vertical height of control of dust rubber strip is higher than the thickness of wiping the felt piece, guarantees to form the control of dust space of sealing.
The beneficial effects of the utility model are, can collect dust easily when wiping the blackboard chalk trace, the flying upward of control dust, and need not electric power, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a control of dust schematic diagram of the present utility model.
Fig. 2 is the shaft side figure of embodiment.
Fig. 3 is the top view of embodiment.
Fig. 4 is A-A cutaway view and the partial enlarged drawing of Fig. 3.
1. base plates among the figure, 2. edge strip, 3. the control of dust rubber strip is 4. wiped the felt piece, 5. blackboard.
The specific embodiment
In Fig. 1, when blackboard eraser was pressed in blackboard 5 surperficial going up, control of dust rubber strip 3, base plate 1, blackboard 5 surfaces formed enclosure spaces, play dust agglutination, and need not electric power.
In embodiment illustrated in fig. 2, the two ends of blackboard eraser are semicircle, and edge strip 2 is positioned at the edge above the base plate, wipe felt piece 4 and are positioned at middle position above the base plate, and control of dust rubber strip 3 is fixed on the edge strip.
In Fig. 3 and Fig. 4, edge strip 2 inboards tilt inwards, and control of dust rubber strip 3 is fixed on the edge strip 2 and slopes inwardly, control of dust rubber strip 3 with wipe felt piece 4 and leave the space, with the storage dust; The vertical height of control of dust rubber strip 3 is higher than the thickness of wiping felt piece 4, guarantees to form the control of dust space of sealing.Control of dust rubber strip 3, base plate 1, blackboard 5 surfaces form enclosure space, play dust agglutination, and need not electric power.
Claims (5)
1. unregulated power control of dust blackboard eraser, base plate, edge strip, wipe the felt piece and place successively, it is characterized in that: on edge strip, place a control of dust rubber strip, when blackboard eraser is pressed on the blackboard surface, control of dust rubber strip, base plate, blackboard surface form enclosure space, play dust agglutination, and need not electric power.
2. unregulated power control of dust blackboard eraser according to claim 1 is characterized in that: the two ends of blackboard eraser make control of dust rubber strip circle suitable for semicircle, and easy and blackboard surface forms enclosure space.
