Abstract
The utility model discloses a blackboard eraser scraper plate which comprises a rectangular frame body (1). A plurality of pairs of long-plate-strip-shaped scraper sheets (2) are arranged in the frame body (1) along the length direction of the frame body (1). Each pair of scraper sheets (2) are composed of a front inclined sheet (2a) and a back inclined sheet (2b), wherein the front inclined sheet (2a) and the back inclined sheet (2b) are systemically arranged and shaped like a Chinese character 'ba'. A gap (2c) is formed between two adjacent scraper sheet pairs (2). A board face of each front inclined sheet (2a) is arranged to form a certain incline angle with a frame face of the frame body (1). Two ends of the front inclined sheet (2a) and the back inclined sheet (2b) are respectively fixed with a corresponding inner frame edge of the frame. By drawing and pulling the frame body, the front inclined sheet and the back inclined sheet of the scraper plate scrap dust in a blackboard eraser repeatedly so that cleaning is convenient. When the blackboard eraser is cleaned, dust can not fly everywhere because of the cooperation of the blackboard eraser scraper plate and an outer box body. When the blackboard eraser is taken out, the dust can not be taken out so that dust pollution is avoided.
Description
Technical field
The utility model relates to a kind of stationery and sporting goods, specifically, and particularly a kind of blackboard eraser scraper plate.
Background technology
Common blackboard eraser is wiped letter written with chalk by fur suede, still, when the letter written with chalk of wiping when blackboard eraser is more, can deposit more dust at the wiping surface of blackboard eraser, and when use the blackboard eraser wiping this moment again, effect is relatively poor, fully the erasing chalk writing.Usually, the people who erases the board can only make dust take from blackboard eraser toward ground or wall arsis blackboard eraser, in the process of removing in bat, can produce more dust, and surrounding environment is formed dust pollution, and the people who claps blackboard eraser is caused health harm; Simultaneously, clap the dust that removes and to fall on the ground or clap on the wall, pollute ground or metope.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of blackboard eraser scraper plate that prevents that dust from disorderly flying.
The technical solution of the utility model is as follows: a kind of blackboard eraser scraper plate, comprise rectangular framework (1), be distributed with many scraping blades to the long slab bar shaped (2) along its length direction in framework (1), every pair of scraping blade (2) is comprised of symmetrically arranged positively biased (2a) and backslash sheet (2b), and positively biased (2a) of every pair of scraping blade (2) and backslash sheet (2b) are " eight " font and distribute, two adjacent scraping blades (2) between have gap (2c); The frame face tilt of the plate face of described positively biased (2a) and framework (1) distributes, and the two ends of positively biased (2a) and backslash sheet (2b) the interior edge corresponding with framework (1) are respectively fixed.
The utility model is by providing a kind of rectangle framework, and arrange many scraping blades to being consisted of by positively biased and backslash sheet in framework, like this, be aided with outside box body, the utility model can be put into box body, simultaneously blackboard eraser is covered on the utility model, pull the utility model, by positively biased wiper with the backslash sheet, dust on blackboard eraser can be scraped, and enter in box body through the gap between scraping blade, thereby prevent that waving of dust from flying, not only simple in structure, the convenience that operates, also environmental protection simultaneously, health.
The angle that is 30-60 ° between the frame face of the plate face of described positively biased (2a) and framework (1) tilts.The angle of 30-60 ° tilts, and when scraping dust on blackboard eraser at positively biased with the backslash sheet, both has been conducive to scrape powder, also is conducive to dust and scrapes afterwards and fall from the inclined-plane.
A wherein end at described framework (1) length direction is provided with handle (3), and this handle (3) is "] " shape.After handle was set, the pull of framework operation was more convenient, and "] " the shape handle is simple and practical.
In order to simplify technique, to reduce costs, facilitate processing and fabricating, described framework (1), scraping blade (2) and handle (3) pass through injection moulding integrated molding.
Beneficial effect: the utility model is by the pull framework, make positively biased of scraper plate repeatedly to scrape with the backslash sheet dust of managing on blackboard eraser, cleaning effect is good, easy to operate, and when coordinating outside box body to use, dust neither can fly around, and also can not come by carry over when taking out blackboard eraser, can not produce dust pollution.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use state diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is made of framework 1, scraping blade 2 and handle 3.Wherein, framework 1 is rectangular dull and stereotyped frame, be distributed with many scraping blades 2 to the long slab bar shaped along its length direction framework 1 is interior, every pair of scraping blade 2 is comprised of symmetrically arranged positively biased 2a and backslash sheet 2b, and positively biased 2a of every pair of scraping blade 2 and backslash sheet 2b are " eight " font and distribute, and have gap 2c between two 2 pairs of adjacent scraping blades; Be the angle tilt distribution of 30-60 ° between the plate face of described positively biased 2a and the frame face of framework 1, the two ends of positively biased 2a and the backslash sheet 2b long frame edge corresponding with framework 1 are respectively fixed.A wherein end at described framework 1 length direction is provided with handle 3, and this handle 3 is "] " shape.Described framework 1, scraping blade 2 and handle 3 pass through injection moulding integrated molding.
As shown in Figure 2, the utility model can be equipped with outside box body 4, and the utility model is put into box body 4, and the utility model can realize that with box body 4 pull coordinates.After blackboard eraser is put into box body 4, can scrape dust on chalkboard eraser by pull the utility model, namely practical simply again.
