Description

A kind of dustproof blackboard eraser sleeve

Technical field

The utility model relates to a kind of dustproof blackboard eraser sleeves.

Background technique

Traditional blackboard wipes plastic simplicity, using the pattern of cuboid, convenient for grip.But its drawbacks of having packet simultaneously It includes: the pollution of chalk dust can not be mitigated；It can not be clean by blackboard-cleaning；Dead angle cannot be removed.Forefathers carry out on this basis Improvement, the overwhelming majority using mechanical, electronic method automatically or semi-automatically wipe letter written with chalk, have and removed using electrostatic Dirt utilizes Electrostatic Absorption dust；Have using high power vacuum cleaner dust suction, powerful pipeline of dust catcher be connected with blackboard eraser, The dust that blackboard eraser is wiped directly is siphoned away by high-power pipeline；Have and brush blackboard by the Wiper system of automobile, but still without solution The problem of certainly dust floats everywhere, while structure is complex, price is also relatively high.

Summary of the invention

The utility model makes improvement for the above-mentioned problems of the prior art, i.e., skill to be solved in the utility model Art problem is to provide a kind of dustproof blackboard eraser sleeve, can not only be dust-proof, facilitates gripping, and structure is simple.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is: dustproof blackboard eraser sleeve include dustproof part and Grip part, the dustproof part connect blackboard eraser far from extending out at grip part relatively close at grip part in dustproof part；Grip part is remote It is fluted from the setting of the side of dustproof part, support frame is set in groove, and support frame is indent streamlined structure, and grip part material is Flexible, grip part is bonded support frame under external force.

Further, the dustproof part is in horn-like, is arranged in the horn-like end of dustproof part to dustproof part infolding Turn of bilge.

Further, protrusion is provided between the dustproof part and blackboard eraser.

Further, the blackboard eraser is connect with blackboard eraser using velcro fastener.

Further, sponge is arranged in the surrounding annular peripheral of end of the dustproof part far from grip part.

Further, dustproof blackboard eraser sleeve is the integrated design, and is formed by 3D printing one-pass molding or mold.

Compared with prior art, the utility model has the following beneficial effects: structure is simple, design rationally, be can be avoided The problem of bringing fugitive dust because of wiping blackboard, it is small in size, it is suitable for producing in enormous quantities；Replaceability sets in the groove of grip part It sets the support frame of different size and holds and use to adapt to different size of hand, usage experience sense is comfortable, more meets ergonomic It learns, applicable crowd is wider.

Detailed description of the invention

Fig. 1 is the stereoscopic schematic diagram of one angle of overall structure of the utility model embodiment；

Fig. 2 is the stereoscopic schematic diagram of another angle of the overall structure of the utility model embodiment.

In figure: 1- dustproof part, the grip part 2-, 3- groove, the protrusion 4-, 5- support frame.

Specific embodiment

The utility model is described in more detail with reference to the accompanying drawings and detailed description.

As shown, dustproof blackboard eraser sleeve includes dustproof part and grip part, the dustproof part is leaned on far from opposite at grip part It is extended out at nearly grip part, blackboard eraser is connected in dustproof part；Side setting of the grip part far from dustproof part is fluted, setting in groove Support frame, support frame be indent streamlined structure, grip part material be it is flexible, grip part is bonded support under external force Frame.The support frame of the setting different size of replaceability holds and uses to adapt to different size of hand in the groove of grip part, Usage experience sense is comfortable, and applicable crowd is wider, and indent streamlined structure meets ergonomics, improves usage comfort.

Further, the dustproof part is in horn-like, is arranged in the horn-like end of dustproof part to dustproof part infolding Turn of bilge.The dust-proof position of the blackboard eraser extends out horn structure using micro-, it is possible to increase the contact surface of blackboard eraser and fugitive dust Dust can be blocked in set to reduce fugitive dust by product.During using blackboard eraser wiping blackboard, it is attached to blackboard Dust is detached from blackboard by the active force of blackboard eraser and floats towards in the air.At this time since the micro- of blackboard eraser extends out horn structure Aerial dust can be covered in blackboard eraser, part dust will be attached in blackboard eraser, and remaining dust is then in blackboard It wipes and is attached to each other in set, and since the factor of gravity falls within ground under in blackboard eraser vertically, thus reach dust-proof effect, it is interior The setting of the turn of bilge of folding further reduces flour dust overflow.

Further, protrusion is provided between the dustproof part and blackboard eraser, protrusion can cooperate a variety of rule with a thickness of 3mm Lattice blackboard eraser uses.The receiving range of blackboard eraser can be increased by increasing thickness at the position for placing blackboard eraser, extend out loudspeaker due to micro- Formula structure, i.e. the increase more thick then open ended blackboard eraser of thickness can be wider.

Further, the blackboard eraser is connect with blackboard eraser using velcro fastener.Using only need when blackboard eraser will be black Blackboard eraser and blackboard eraser need to only be torn when not in use in the bottom of blackboard eraser, can reach easy disassembly by blackboard eraser hasp Effect.

Further, the material of the absorption dust such as surrounding annular peripheral setting sponge of end of the dustproof part far from grip part Matter so can be improved the ability that dust is attached in blackboard eraser, also conveniently removed cleaning due to the loose nature of sponge.

Dustproof blackboard eraser sleeve is integrally the integrated design, can directly be passed through using succinct space multistory formula arcuate structure The quick one-pass molding of 3D printing can also rely on mold molding.

In the present embodiment, the material of blackboard eraser is plastics or rubber.

In the present embodiment, the groove of the top setting of the blackboard eraser, makes it have both storage and receives function, can place chalk Etc. lesser article.

Blackboard eraser when in use, by blackboard eraser by velcro fastener be arranged in dustproof part, according to use blackboard eraser it The support frame of the size selection dimension of the hand of people, and the support frame chosen is placed in the groove of grip part, holding is in one's hands It holds portion and applies external force, make grip part patch and support frame, and meet the hand of user, a part of dust meeting during erasing the board Fall on the ground, a part can stay in turn of bilge, and the dust of turn of bilge is poured into dustbin by rotating angle, it is remaining be attached to it is black Dust in blackboard eraser set cleans in time；It substitutes in use, such as primary school teacher's and pupil is used alternatingly, because of grip part To be flexible, original support frame need to only be taken out with hand, be put into the support frame being suitble to i.e. by the hand of user.Usually When not used, groove can realize that storage is received.

Above-listed preferred embodiment has been further described the purpose of this utility model, technical solution and advantage, It should be understood that the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical Within novel protection scope.

The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the patents it is equal Deng variation and modification, it should all belong to the covering scope of the utility model.
