Description
Technical field
This utility model is related to teaching aid technical field, more particularly to a kind of rock type purely mechanic blackboard eraser.
Background technology
The mode for erasing the board at present mainly has：（1）Traditional blackboard sassafras is manually used, and this blackboard eraser is cheap and compact,
But its using cycle very short and the effect that erases the board is not ideal, arduously time-consuming and limited by height.The another biography equipped with extension bar
Although system blackboard eraser overcomes the difficult problem that teacher of short and small stature erases the board, but still cannot equally avoid its common problem.（2）Make
With electronic blackboard eraser device to reach the effect of saving time and manpower, but its cost intensive, therefore its using be subject to compared with
Big restriction.（3）The effect for quickly erasing the board is reached using the blackboard cleaning device of mechanical rain brush or roller shutter operation principle, and the former uses
Electronic mode is expensive, blackboard is then replaced with two-sided soft blackboard by the latter, expend larger and during reeling soft blackboard, by
In unstability, the effect for erasing the board is caused significantly to reduce.As can be seen here, aforesaid way have the shortcomings that larger,
There is very big restriction in current application and popularizations, so the whole nation causes to wipe in a large number using traditional blackboard cleaning device at present
The dust of blackboard person is sucked and is wasted time and energy.
Content of the invention
For solve existing free-hand erase the board waste time and energy, electronic blackboard cleaning device expensive price and other blackboard cleaning devices low
The problem of efficiency, the utility model proposes a kind of rock type purely mechanic blackboard eraser.
For this purpose, the technical solution of the utility model is：Rock type machine blackboard sassafras, including drive mechanism, it is characterised in that：
The drive mechanism includes that upper and lower gate shafts, two gate shafts are set in parallel in the upper and lower ends of blackboard, in the centre of two gate shafts
Screw pair is provided with parallel to gate shafts, manual rocker is connected with by shaft coupling in one end of downslide fluted shaft, in manual rocker
The first transmission belt is provided between bar portion and the leading screw of screw pair, between the leading screw and upper hopper chute axle of screw pair is provided with the second transmission
Band；Gag lever post is connected with the screw of screw pair, is connected to upper and lower brush body, the upper and lower ends point of gag lever post on gag lever post
Gear mechanism Tong Guo not bored bonded with upper and lower gate shafts, cone gear mechanism includes that bevel gear, driven pulley, driven pulley are nibbled with bevel gear
Close and arrange, belt wheel is respectively equipped between driven pulley and upper and lower brush body, also is provided with belt wheel, upper and lower brush body between upper and lower brush body
Can move left and right along gate shafts and rotation.
Operation principle：
During use, artificial shake manual rocker provides power and is transmitted by Liang Ge branches respectively.One of branch by
First transmission belt drives the leading screw of screw pair to rotate, and converts torque into thrust, promotes the screw on leading screw for linear motion, from
And drive upper and lower brush body to move left and right, realize the function of erasing the board；Another branch drives downslide fluted shaft to rotate by shaft coupling,
The rotation of lower brush body realized by downslide fluted shaft by cone gear mechanism bonded with which；In the same manner, driven by the second transmission belt sliding
Fluted shaft is rotated, you can the rotation of brush body in realization, so as to reach the effect for efficiently erasing the board.
Shaft coupling can be also disconnected, lower brush body is screwed, lower brush body is separated with blackboard surface；The rotation work(of this brush body at present
Can fail, most of kinetic energy is used for the motion of upper brush body, and lower brush body is moved under gag lever post and leading screw effect, but is divided with blackboard surface
From the effect that a plate retains a plate is wiped in realization.
Beneficial effect：
This utility model has damping effect using drive belt configuration, improves the stability of device；Using spiral slave
Rotational motion is converted into linear motion by structure, efficiently can transmit kinetic energy at a distance；Rotation direction is achieved using cone gear mechanism
Change, and high efficiency smooth.The blackboard eraser simple structure, ruggedness, good reliability, by reconstruction unit part, can meet difference
The use of occasion；It is time saving and energy saving to be erased the board using the blackboard eraser, and noise is low, and efficient, environmental protection, life-span length are economical and practical；And overcome
Height restriction, easy to use.
