Description

A kind of novel chalk is wiped

The utility model relates to a kind of novel chalk and wipes.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliances, and the big class of office appliance is write or drawing article, the assistant product group of writing or draw, the cleaning device technical group field of blackboard or slabstone.Be numbered B43L21/00.

At present, remove the demand of letter written with chalk when the technology about the cleaning device of blackboard or slabstone existing and that once had is utilized the chalk writing board book to people and all did very fruitful effort, once designed many outstanding technical schemes.As January 4 nineteen ninety-five the Decree of Patent Office of China by but Declare in the pool, and Granted publication number for CN2186669Y China Patent No. (ZL) is: 94227458.X number utility model title is the utility model patent of " making things convenient for dust absorption blackboard eraser ", the technical scheme that is adopted.Cleaning device technical elements at blackboard or slabstone is a routine of great value invention, and it has solved the problem of utilizing cylinder brush body cleaning blackboard and making things convenient for dust suction effectively.But because the square felt erasing blackboard of widespread usage is wiped in still widely use traditionally, so also be difficult to solve the problem that is transformed into the multifunctional ceiling dust of the black wiping of existing plate now.

The purpose of this utility model is to provide a kind of novel chalk to wipe.To have the problem that blackboard eraser is transformed into the multifunctional ceiling dust now to solve.

The purpose of this utility model is achieved in that a kind of novel chalk wiping of this utility model.Mainly by chalk rub body, burlap, support, goo, deposit chalk dust elongated slot, slide rail, support fixedly screw, chalk wiping carpet brush constitute.Its major part chalk rub body, burlap, goo support hold-down screw, select for use by market.Support, deposit chalk dust elongated slot, slide rail, use steel; Iron plate is the raw material processing and manufacturing.On common chalk rub body, support is installed, and be fastened on the chalk rub body with the support hold-down screw, cover is loaded onto burlap on support, be used for the wiping dust, around the chalk rub body 4 slide rails are installed, by slide rail four leg-of-mutton chalk dust elongated slots of depositing are installed, the medial surface of depositing the chalk dust elongated slot adheres to the goo (as molten glue) that one deck can paste chalk dust, depositing the chalk dust elongated slot can arbitrarily pull out and put into from slide rail, so that clean as required at any time.Molten glue class goo can be prepared to brush at any time.So just realized the purpose of this utility model.

The utility model has been compared two advantages and improvement with the technology of the cleaning device of original blackboard or slabstone;

The first and since the utility model in technical scheme, designed support is installed on the chalk rub body and on support the cover load onto burlap, this has just increased the function of dust on the chalkboard eraser wiping miscellaneous equipment.

The second and since the utility model in technical scheme, designed with goo deposit the chalk dust elongated slot, so just make to chalk dust enters elongated slot to be attached in the groove by suction, prevented dust from flying.Thereby just can more effectively solve and to have had the problem that blackboard eraser is transformed into the multifunctional ceiling dust now.

Accompanying drawing provides structural representation of the present utility model:
