Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of blackboard wiping convenience, high, the effective blackboard convenient for cleaning of efficient are provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises blackboard, the last lower edge of its structural feature blackboard is respectively arranged with the bar shaped slideway, the upper/lower terminal of slide bar is separately positioned in the described slideway, and the lower end of slide bar is provided with pulley corresponding to slideway, and described slide bar links to each other with wiping board by spring, wiping board is provided with wiper, and wiper places described blackboard surface; Described spring is two, is arranged at the both sides up and down of described slide bar respectively; The upper end of described slide bar is provided with anti-down fixture block perpendicular to the direction on blackboard surface, and the sidewall of described slideway is provided with the fixture block groove corresponding to fixture block.
As a kind of preferred version, the lower edge of blackboard described in the utility model is provided with the bar shaped water collector, and the lower edge of water collector and blackboard is movably connected.
As another kind of preferred version, slide bar described in the utility model, pulley, fixture block, spring, wiping board, wiper be combined as two groups.
In addition, an end of slideway described in the utility model is provided with caging bolt.
The utility model beneficial effect
1, blackboard wiping is convenient, efficient is high, effective
The last lower edge of the utility model blackboard is respectively arranged with the bar shaped slideway, and the upper/lower terminal of slide bar is arranged in the described slideway, and described slide bar links to each other with wiping board by spring, and wiping board is provided with wiper, and wiper places described blackboard surface; Described spring is two, is arranged at the both sides up and down of described slide bar respectively; The upper end of described slide bar is provided with anti-down fixture block perpendicular to the direction on blackboard surface, and the sidewall of described slideway is provided with the fixture block groove corresponding to fixture block; Can drive the wiper blackboard wiping by the slip slide bar, because spring places the slide bar both sides, so almost the vertical length with blackboard is consistent for the vertical length of wiping board, the efficient height just can all be clipped the monoblock blackboard by the slide bar that slides like this No. a time.And slide bar is to link to each other with wiping board by spring, and it is tight that wiper and blackboard surface contact, makes wiping effect better.Because the effect of fixture block, when slide bar was desired to topple over, fixture block just was stuck on the lower plane of fixture block groove, prevented toppling over of slide bar.So the utility model blackboard wiping is convenient.
2, be convenient to clear up dirt
The lower edge of the utility model blackboard is provided with the bar shaped water collector, and the lower edge of water collector and blackboard is movably connected, and water collector can be collected water and the chalk dust that stays from blackboard and wiper, when needs cleaning water collector, water collector can be taken out cleaning from the blackboard lower edge.So the utility model is convenient to clear up dirt.
3, be convenient to thoroughly clean blackboard
The utility model slide bar, spring, pulley, fixture block, wiping board, wiper be combined as two groups; One group is wet wipes, and another group is xerotripsis cloth, can dry blackboard with xerotripsis cloth more earlier with wet wipes cleaning blackboard surface like this, not only can thoroughly clean blackboard, and be convenient to blackboard surface rapid draing, is beneficial to people's use.
4, easy to use, safe
One end of the utility model slideway is provided with caging bolt; The shank of bolt of caging bolt can be prevented the slip of limited slip wheel, so just can avoid because people's the slideway that because of carelessness slide bar skidded off causes danger and inconvenience.
