The specific embodiment:

Be embodiment of the present utility model with accompanying

drawing

1,2,3,4,5 below, the utility model be further detailed:

The utility model comprises a box body 4 and the tube wiping that is located in the box body 4, and described box body 4 is the open state box body, can be that transparent plastic is made, and box body 4 will leave the space of splendid attire chalk dust.In described box body 4, be provided with wiping 3 of lockable tube and rotary cylinder and wipe 31, below described lockable tube wiping 3 and rotary cylinder wiping 31, be equipped with cleaning brush 12.It is identical that the wiping 3 of described tube lockable tube is wiped a structure with the tube of rotary cylinder wiping 31.The inside that tube is wiped is the cylinder 8 of a hard, and cylinder 8 outer surfaces are made more coarse, and wiper 9 is made cylinder type, and its inner surface is littler than outer surface of cylinder, utilizes cylinder 8 on the resilient sleeve of wiper 9, can make like this wiper tightly encase cylinder and non-slip.A described lockable tube wipes 3 in the centre of box body 4, respectively establishes a rotary cylinder on the both sides of described lockable tube wiping 3 and wipes 31.Described lockable tube wiping 3 is wiped and can be wiped letter written with chalk easily during use, wiping 31 powder of wiping by the rotary cylinder on both sides simultaneously sweeps away, when rotary cylinder wipes 31 when turning to the space of splendid attire chalk dust of the box body 4 that is provided with cleaning brush 12, whitewash the pen that sticks in the rotary cylinder wiping 31 clean by cleaning brush, the space of splendid attire chalk dust, simultaneously rotary cylinder is wiped 31 and clean down, make the tube wiping on both sides can keep clean for a long time like this, make the phenomenon that does not just have chalk dust swarming everywhere when erasing the board.After tube is wiped use a period of time, the lockable tube is wiped long-pendingly on 3 to be had more chalk dust and influences when using effect, at this moment can open the locking switch 6 that the axle head of lockable tube wiping 3 is established, tube in the middle of making is wiped and can be rotated, make it to rotate or on blackboard, make it rotation with hand, allow cleaning brush can the ash that tube smears be cleaned down, afterwards the lockable tube of centre is wiped 3 lockings, promptly can continue to have used.Can see what of a powder in dress powder space by transparent box cover 7, long-pending when to a certain degree influence result of use when a powder, can open 7 powder of lid of transparent box body and outwell.

The lubricating requirement that tube wiping rotation is considered in filial piety is not high, therefore is designed to the structure that this not tape spool holds.Simultaneously in order to prevent that axle breaks away from axis hole, suitable position at axle 1 is equipped with circlip 2, shaft head has been made the square bigger than axle body, be for fixed axis, the installation that this structure is wiped tube becomes more or less freely, as long as aim at the axis hole 10 of tube wiping the axle on both sides is inserted, and first-class circlip 2, and tube is wiped and is just installed son.For good contact of keep clean brush 12 and tube wiping, described cleaning brush 12 is located in the brush groove 14; In described brush groove 14, be provided with spring 15.Cleaning brush 12 is to wipe 3,31 at tube to put in the position that tube is wiped before installing or open transparency cover and put in the place of lid mouthful together with the installation of spring 15, cleaning brush 12 has certain retractility under the effect of spring 15, cleaning brush 12 can be wiped tube keep excellent contact.The utility model is endways during use, under the few situation of the powder in the dress powder space to not influence of use of the present utility model.11 dividing plates for dress powder space.
