The utility model has the advantages of reasonable design, convenience simple to use drives through telescopic cylinder that the blackboard eraser is automatic to make a round trip to clean the blackboard, and blackboard eraser cover lower extreme is equipped with during the drawing fan can inhale lower extreme dust box with the dust moreover, labour saving and time saving promptly, and the effectual dust of having avoided too much causes harm to teachers and students respiratory again.

Description

A kind of new no-dust driven blackboard
Technical field
The utility model relates to teaching tool technical field, especially a kind of new no-dust driven blackboard.
Background technology
Blackboard to be imparted knowledge to students tool as one, is widely used in school sessions or training and teaching, at present, the blackboard majority that general school uses is traditional hard blackboard, need artificial erasing chalk word, when erasing the board, dust wafts full classroom, is in this environment for a long time, teachers and students are easily caused to suffer from respiratory disease, damage the healthy of teachers and students, and when blackboard writing content is too much, blackboard wiping is wasted time and energy, occupy a lot of valuable instructional blocks of time, have impact on teaching, training effect.
Utility model content
The purpose of this utility model provides a kind of new no-dust driven blackboard to overcome above-mentioned technical disadvantages.
The technical scheme that the utility model technical solution problem adopts is: a kind of new no-dust driven blackboard, comprise blackboard, blackboard eraser, drawing fan, dust box, blackboard eraser cover, telescopic cylinder, expansion link, the upper and lower two ends of described blackboard are provided with gathering sill, blackboard eraser cover is provided with before blackboard, blackboard eraser is provided with in blackboard eraser cover, blackboard eraser cover lower end is provided with drawing fan, dust box is provided with below drawing fan, telescopic cylinder is provided with on the right side of blackboard, telescopic cylinder is provided with expansion link, and expansion link one end connects the rolling wheel support centre position at blackboard back.When opening telescopic cylinder, expansion link is stretched back and forth, drive rolling wheel support to move back and forth, thus drive blackboard eraser Automatic erasing blackboard back and forth, time saving and energy saving, easy to use.
Described blackboard eraser cover two ends are provided with rotating shaft, and rotating shaft is provided with roller, and roller can roll on the gathering sill at the upper and lower two ends of blackboard, and the rotating shaft other end connects rolling wheel support, and rolling wheel support is positioned at the blackboard back side.Roller and gathering sill match and roll, and decrease the resistance that blackboard eraser cover moves back and forth, and are convenient to blackboard eraser cover fixed position and guided-moving direction, easy to use and reliable.
Described telescopic cylinder and drawing fan are equipped with power line, and power line is connected with gauge tap.When opening gauge tap, telescopic cylinder drives blackboard eraser blackboard wiping back and forth, and drawing fan rotates and sucked in dust box from blackboard eraser cover by dust simultaneously.
The beneficial effect that the utility model has is: reasonable in design, easy to use, blackboard eraser automatic back-and-forth blackboard wiping is driven by telescopic cylinder, and blackboard eraser cover lower end is provided with drawing fan and dust can be sucked in the dust box of lower end, namely time saving and energy saving, effectively avoid again dust and cross multipair teachers and students' respiratory system and work the mischief.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
Be described below below in conjunction with accompanying drawing 1 pair of the utility model.
As shown in Figure 1, the utility model comprises blackboard 1, blackboard eraser 3, drawing fan 4, dust box 5, blackboard eraser cover 2, telescopic cylinder 10, expansion link 9, described blackboard about 1 two ends are provided with gathering sill 13, blackboard 1 is provided with blackboard eraser cover 2 above, blackboard eraser 3 is provided with in blackboard eraser cover 2, blackboard eraser cover 2 lower end is provided with drawing fan 4, drawing fan 4 is provided with dust box 5 below, telescopic cylinder 10 is provided with on the right side of blackboard 1, telescopic cylinder 10 is provided with expansion link 9, and expansion link 9 one end connects rolling wheel support 8 centre position at blackboard 1 back.When opening telescopic cylinder 10, expansion link 9 is stretched back and forth, rolling wheel support 8 is driven to move back and forth, thus drive blackboard eraser 3 Automatic erasing blackboard 1 back and forth, time saving and energy saving, easy to use, and the dust produced during blackboard eraser 3 wiping covers by blackboard eraser cover 2, sucks in lower end dust box 5 under drawing fan 4 acts on.
Described blackboard eraser cover 2 two ends are provided with rotating shaft 7, and rotating shaft 7 is provided with roller 6, and roller 6 can roll on the gathering sill 13 at blackboard about 1 two ends, and rotating shaft 7 other end connects rolling wheel support 8, and rolling wheel support 8 is positioned at blackboard 1 back side.Roller 6 rolls on gathering sill 13, decreases the resistance that blackboard eraser cover 2 moves back and forth, and upper bottom roller 6 is placed in gathering sill 13, can fix blackboard eraser cover 2 position, makes blackboard eraser 3 be close to blackboard 1 and guided-moving direction, easy to use and reliable.
Described telescopic cylinder 10 and drawing fan 4 are equipped with power line 12, and power line 12 is connected with gauge tap 11.When opening gauge tap 11, telescopic cylinder 10 drives blackboard eraser 3 blackboard wiping 1 back and forth, and drawing fan 4 rotates and sucked in dust box 5 from blackboard eraser cover 2 by dust simultaneously.
During use, open gauge tap 11, telescopic cylinder 10 can control expansion link 9 stretching motion back and forth, drive rolling wheel support 8 to move back and forth, thus roller 6 is moved back and forth on gathering sill 13, drive blackboard eraser 3 Automatic erasing blackboard 1 back and forth in blackboard eraser cover 2, during wiping, drawing fan 4 is opened simultaneously, sucks in dust box 5, closing control switch 11 after wiped clean by the dust produced during wiping.
