Abstract
The utility model discloses a hand rotated auto erasing non powder blackboard, relating to a blackboard. An upper roller is surrounded with a seamless annulus belt shaped board, an lower pattern roller shaft is fixed on the force bearing frame, a supporting board is fixed on the face of the force bearing frame to support the seamless annulus belt shaped board, a powder collecting box is positioned below the lower pattern roller, a chalk erasing box is positioned on the powder collection box, and the lower pattern roller is driven by a gear in a rocker gear case. When the utility model is used, the rotating handle is rotated, the lower roller is driven by the gear group, so that the seamless annulus belt shaped board is driven to do circulation movement. The chalk letters can be written on the seamless annulus belt shaped board supported by the supporting board, after the writing, the handle is rotated continuously, the writing board with chalk letters from back is turned to chalk erasing box, the chalk letters are erased by the chalk erasing box automatically, and the powder drops in the powder collecting box to avoid the powder pollution. The utility model has the advantages of simple structure, very thin thickness, light weight, low fabrication cost, easy operation, convenient fabrication process, and no powder pollution.
Description
Technical field
The utility model relates to a kind of blackboard, is specially to wipe chalk dust automatically, and dustless blackboard.
Background technology
" a kind of two-sided turning lifting blackboard " (patent No. 03233857), it is made up of mainboard, subplate, tooth bar and holddown groove, mainboard is installed in the holddown groove, can move along tooth bar is upper and lower, four jiaos of mainboard are provided with fastener, subplate is fixedly mounted in the holddown groove of mainboard rear, in the holddown groove of subplate top locking device is housed.Be provided with steady pin and turning groove in the holddown groove." a kind of rotary Double-purpose blackboard of wiping automatically " (patent No. 02259136), comprise parts such as back shroud, plank support, roller bearing, the canvas space of a whole page, hand runner, fix the dust baffle of coarse wool brush, constant slope on the described back shroud successively, vertically placing dust guide groove, fine, soft fur brush, dust box, the upper/lower terminal of described plank support is connecting respectively goes up rotating shaft and lower rotary shaft, the canvas space of a whole page is contained on the plank support that assembles, back shroud and plank support are tightly connected.Owing to adopt said structure, drive the rotation of the cloth matter space of a whole page by upper and lower rotating shaft, only need rotate the hand runner during upset, the coarse wool brush and the fine, soft fur brush that are arranged on the back shroud are scrubbed the space of a whole page automatically, and the dust that brush falls is collected into dust box through dust baffle and guide groove.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aim to provide a kind of simple and reasonable, ultrathin, in light weight, cost is low, operation, easy to process easily, the rotatable automatic erasing dust-free blackboard of the hand of no dust pollution.
The implementation of the utility model purpose is, the rotatable automatic erasing dust-free blackboard of hand, upper roller 10, following annular knurl roller 11 roll shafts are fixed on the framework of load-bearing frame 2, plate face fagging 12 is fixed on the frame face of load-bearing frame 2, seamless endless belt-shaped plate face 1 is walked around upper roller 10, following annular knurl roller 11, plate face fagging 12, following annular knurl roller has for 11 times chalk dust to collect box 8, chalk dust is collected on the box has chalkboard eraser to wipe box 6, and chalkboard eraser is wiped box 6 near seamless endless belt-shaped plate face 1, rocker gear box 4 dress turning handles 5, the gear 14 of dress turning handle 5 and gear 13 engagements, gear 13 is coaxial with following annular knurl roller 11.
When using the utility model, rotate turning handle 5, by gear 14,13 drive annular knurl roller 11 down, thereby drive seamless endless belt-shaped plate face 1 and make shuttling movement, seamless endless belt-shaped plate face 1 front is supported by plate face fagging 12 and is in smooth stress, can bear relevant pressure when writing letter written with chalk and indeformable, can arbitrarily write letter written with chalk in the above, after the space of a whole page has been write, be rotated further turning handle 5, by the plate face of letter written with chalk by after go to chalkboard eraser and wipe box 6, chalkboard eraser is wiped 6 pairs of automatic wipings of letter written with chalk of box, chalk dust falls into chalk dust and collects in the box 8, has avoided dust pollution.
The utility model is simple and reasonable, ultrathin, in light weight, cost is low, easy operation, easy to process, no dust pollution.
