The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Please refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is the dustless antifouling blackboard eraser cutaway views of two Scrolls of the utility model embodiment; Fig. 2 is the right side view of the dustless antifouling blackboard eraser of two Scrolls of the utility model embodiment; Fig. 3 is the left side view of the dustless antifouling blackboard eraser of two Scrolls of the utility model embodiment.The dustless antifouling blackboard eraser of two Scrolls of present embodiment comprises: first spool 1, second spool 2, base plate 3, wiper 4 and shell 6; Described wiper 4 is walked around base plate 3, and its two ends are separately fixed on first spool 1 and second spool 2; One end of described first spool 1 and second spool 2 is provided with first handwheel 11 and second handwheel 12 respectively; The described wiper 4 and first spool 1 and second spool, 2 junctions are adopted and are flexibly connected; The both sides of described shell 6 are respectively equipped with the slit, are used for the turnover of wiper 4; Described shell 6 forms a cavity with base plate 3, and described first spool 1 and second spool 2 are arranged in the cavity.It is also fixing by the mode combination that engages with base plate 3 that described shell 6 is provided with one handle 10 described shells 6; One side of described base plate 3 is provided with a skid resistant course 5.
Please refer to Fig. 4, Fig. 5, Fig. 4 is the base plate and the antiskid plate structure chart of the dustless antifouling blackboard eraser of two Scrolls of the utility model embodiment; Fig. 5 is the bulge-structure figure on the antiskid plate of the dustless antifouling blackboard eraser of two Scrolls of the utility model embodiment.In the present embodiment, described skid resistant course 5 surfaces are provided with some protruding 8, described protruding 8 and are provided with strip groove 9, and described protruding 8 is hemispherical.
Concrete: this device is made of shell (containing handle), base plate, wiper, spool and adjunct, base plate is as the inner support of this device and the collet of wiper, its two ends difference spooling was on two spools after wiper was walked around base plate, one end of each spool is equipped with the handwheel that rotating scroll is used, and the shell that has a handle is fastened on the base plate and covers the spool that is twining wiper.
Rubber antiskid layer on the base plate plays to be supported wiper and wiper is closely contacted with blackboard, it is smoothly mobile smoothly that unique elastomeric material makes wiper can accomplish that when wiping good braking can be close to skid resistant course again under the drive of handwheel, after the wiper on the skid resistant course is wiped dirt, rotate handwheel and just the wiper that pollutes can be involved in inner chamber, roll out clean wiper simultaneously.Special circumvolution design cooperates the reasonable slit between base plate and the shell, makes wiper turnover easily under the effect of handwheel external force, is difficult for hauling-out during no handwheel external force again.Tried enough wiper length has satisfied the blackboard wiping demand of a class hour.The wiper two ends are adopted with corresponding spool and are easily connect structure, and the break disassembly, cleaning are very convenient.Pure frame for movement is durable, meets middle and primary schools and uses actual conditions.
Adopt moistening wiper to wipe the principle of chalk dust, the ingenious cooperation between utilizing the mechanical device transmission and elastomeric material being braked, accomplished moving freely and reliable braking of wiper.
One of inventive point of the present utility model is to have worked out suitable elastomeric material and surface texture, found fixing with mobile critical point, solved moving and fixation problem of wiper. two are novel blackboard eraser structures of utilizing two moistening wipers of spool spooling and under the handwheel scrolling, can upgrading wiping surface flexibly, solved traditional blackboard and wiped and make chalk dust fly away the harm that brings to the classroom teachers and students. three be to utilize the flexible rotation that opposite rotation direction of two spools and opposite layout guaranteed wiper and be difficult for hauling out.
Above content be in conjunction with concrete optimal technical scheme to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
