Description
Technical field
The present invention relates to educational aid technical fields, specifically a kind of novel blackboard eraser.
Background technology
Blackboard eraser is the instrument that school instruction often uses in the process, especially in the class, is needing to wipe
On blackboard when writing, it is necessary to use blackboard eraser.
When traditional blackboard is used to wipe the font on blackboard wiping, the amplitude of brandishing blackboard eraser is bigger, frequency is higher, then dust
More obvious, neighbouring academics and students are drifted everywhere unconscious to suck in lung them, in the course of time, can influence teachers and students
Health.Therefore, the dust generated when how to handle blackboard eraser blackboard wiping is a stubborn problem.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of simple in structure, design rationally, make
With convenient novel blackboard eraser, have the function that collect dust by the mechanical movement of annular brace bar and apron, hairbrush is in plate
Dancing in the air for dust can be reduced by wiping in motion process, have the effect of environmental protection.
To achieve the above object, the technical solution adopted by the present invention is：A kind of novel blackboard eraser, comprising converse force block,
Felt, fixed pin, lever annular support, fixing piece, hairbrush, substrate, annular rectangular channel and anti-dust leakage set, the substrate are
Rectangular shape, the outside of the substrate are enclosed with anti-dust leakage set, and the upper surface of the substrate is along its profile length and width side
To equipped with annular rectangular channel, the annular rectangular channel is internally provided with hairbrush, and the upper surface of the substrate passes through fixed gluing
Felt is connected to, and is bonded with hairbrush, the outside of the hairbrush is equipped with ring-shaped lever support, and the ring-shaped lever support is along length side
To both ends central bottom be provided with fixing piece, the fixing piece passes through fixed pin connection, the fixation with lever annular support
The upper end of part is provided with converse force block.
Further, the outside interplanar distance of the annular rectangular channel and substrate is 3-4mm, and the groove depth of the annular rectangular channel is
1.5-2mm。
Further, the height of the hairbrush covers low 1-2mm than the leakage of anti-dust.
Further, the spacing between the lever annular support and hairbrush is 0.5-1mm, and the lever annular support is with preventing
Spacing between dust leakage set is 0.5-1mm.
Further, the fixing piece passes through fixed glue sticking with substrate.
Further, setting is fluted among the both sides of the felt, and the groove matches with converse force block.
With the above structure, beneficial effects of the present invention are：The configuration of the present invention is simple, design is reasonable, by it is converse by
Power block swings back and forth with wiping direction, and lever annular support is caused to strut the one side of anti-dust leakage set and receive opposite side
Tightly, by dust collection in anti-dust leakage set, hairbrush can reduce powder in blackboard eraser motion process for mechanical movement in this way
Dirt dances in the air, and has the effect of environmental protection, reduces environmental pollution, be conducive to the physical and mental health of teachers and students.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with attached drawing and specific implementation
Mode, the present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are only explaining this
Invention, is not intended to limit the present invention.
Referring to shown in Fig. 1 to Fig. 4, present embodiment uses following technical scheme：A kind of novel blackboard eraser, comprising inverse
Anti- force block 1, felt 2, fixed pin 3, lever annular support 4, fixing piece 5, hairbrush 6, substrate 7, annular rectangular channel 7-1, anti-powder
Dirt leakage set 8, the substrate 7 are rectangular shape, and the outside of the substrate 7 is enclosed with anti-dust leakage set 8, the substrate 7
Upper surface be equipped with annular rectangular channel 7-1 along the long cross direction of its profile, the annular rectangular channel 7-1's is internally provided with hairbrush
6, the upper surface of the substrate 7 is bonded with felt 2 by fixing glue, and is bonded with hairbrush 6, and the outside of the hairbrush 6 is equipped with ring
Shape lever support 4, the both ends central bottom of the ring-shaped lever support 4 along its length are provided with fixing piece 5, the fixing piece
5 are connected with lever annular support 4 by fixed pin 3, and the upper end of the fixing piece 5 is provided with converse force block 1.
The outside interplanar distance 4mm of the annular rectangular channel 7-1 and substrate 7, the groove depth of the annular rectangular channel 7-1 is 2mm.
The height of the hairbrush 6 leaks outside than anti-dust covers 8 low 1mm.
Spacing between the lever annular support 4 and hairbrush 6 is 1mm, and the lever annular support 4 leaks outside with anti-dust
Spacing between set 8 is 1mm.
The fixing piece 5 passes through fixed glue sticking with substrate 7.
Setting is fluted among the both sides of the felt 2, and the groove matches with converse force block 1.
The operation principle of present embodiment：When using blackboard eraser, when wiping letter written with chalk on blackboard, felt 2 wipes chalk
Word, 6 head of hairbrush by after curved with the direction of motion on the contrary, overstocking dust between hairbrush 6 and felt 2, stop dust is from blackboard
On fly upward, simultaneously because converse force block 1 with the blackboard eraser direction of motion on the contrary, causing the lever annular support 4 to be with fixed pin 3
Pivot, the opposite side tightening for the anti-dust leakage set 8 for strutting equidirectional anti-dust leakage 8 one sides of set and making negative direction,
Most dust collection is covered in the leakage of anti-dust in 8 at last.
Present embodiment is simple in structure, and design is reasonable, by converse force block as wiping direction swings back and forth, causes
