Abstract

The utility model discloses a laborsaving blackboard eraser, including last guide rail, pulley, blackboard eraser, pushing hands and lower guideway, last guide rail fix on the blackboard, the lower guideway fix below the blackboard, pulley and last guide rail, lower guideway sliding fit, the blackboard eraser fix between two pulleys, the pushing hands be connected with the blackboard eraser. The utility model discloses a go up the sliding fit of lower guideway and pulley, realized the technical problem of the quick laborsaving board of blacking, but through be provided with elevating gear and pushing hands on the blackboard eraser to the people who is fit for different heights uses the blackboard eraser, through set up fixing device on the lower guideway, the automatic slip of pulley has been avoided, storing dirt and depositing ash box through being connected with on the lower guideway, the people of being convenient for clear up chalk dirt fast, and the global design practicality is strong, easily realizes.

Description

A kind of Labor-saving blackboard eraser

Technical field

The utility model relates to realia field, particularly relates to a kind of Labor-saving blackboard eraser.

Background technology

Blackboard be one can the flat board of repeated writing, plate face is hard, be used for teaching, although multimedia use is increasingly extensive, but at present in most of areas of China, be still and use traditional blackboard to be used as educational aid, blackboard is after writing, need to use blackboard eraser to clean totally, but traditional blackboard eraser head is less, student or teacher need repeated multiple times wiping, not only require great effort but also suck dust-proof also many, certain hidden danger is also existed to the health of student and teacher, and a lot of pupil can't reach above blackboard, need to step down in wiping on stool, there is potential safety hazard.

For this phenomenon, a lot of human hair understands automatic blackboard eraser, blackboard eraser is driven to run by electricity, complete the work erased the board, laborsaving and easy to use, but use inevitable power consumption frequently, chalk dust also can not disappear because of automatic erasing, and structure relative complex, cost is more expensive, is not easy to promote.

Utility model content

The utility model provides a kind of Labor-saving blackboard eraser for solving the problem, and by being slidably matched of upper/lower guide and pulley, achieves the technical problem that fast power-saving erases the board; By being provided with apparatus capable of fluctuating and pushing hands on blackboard eraser, use blackboard eraser with the people of applicable different height; By arranging fixture on lower guideway, avoiding pulley and automatically sliding; Deposit grey box by being connected with storage dirt on lower guideway, be convenient to people and clear up chalk dust fast, global design is practical, is easy to realize.

The purpose of this utility model is by realizing with under type:

A kind of Labor-saving blackboard eraser, comprise upper rail, pulley, blackboard eraser, pushing hands and lower guideway, described upper rail is fixed on above blackboard, described lower guideway is fixed on below blackboard, described pulley and upper rail, lower guideway are slidably matched, described blackboard eraser is fixed between two pulleys, and described pushing hands is connected with blackboard eraser.

Further, described lower guideway is connected with fixture, described fixture and pulley are connected.

Further, described lower guideway is provided with opening, described opening is connected with storage dirt and deposits grey box, and described storage dirt is deposited grey box surface and is provided with handle.

Further, described blackboard eraser is provided with apparatus capable of fluctuating, described apparatus capable of fluctuating is connected with pushing hands.

Further, described upper rail and lower guideway are provided with arc groove.

Further, described upper rail, lower guideway and blackboard eraser surface is with one deck flexible material, and described flexible material is TPU or TPE or TPR or silica gel or rubber.

The beneficial effects of the utility model are:

A kind of Labor-saving blackboard eraser, by being slidably matched of upper/lower guide and pulley, achieving the technical problem that fast power-saving erases the board, decreases people and suck the dust-proof time, to a certain degree reduce down the injury that dust causes people's health; By being provided with apparatus capable of fluctuating and pushing hands on blackboard eraser, use blackboard eraser with the people of applicable different height; By arranging fixture on lower guideway, avoiding pulley and automatically sliding; Deposit grey box by being connected with storage dirt on lower guideway, be convenient to people and clear up chalk dust fast, global design is practical, is easy to realize.
