Abstract
The utility model relates to a teaching articles for use, the name is electric blackboard that optional was cleaned, including the framework, spool and time spool having in the framework on also have annular coiled material cover at last spool under and between the spool lower spool the outside in addition and its parallel arrangement clean the spool in the framework, framework side the rectangular hole that length set up from top to bottom has, the spool of cleaning install in rectangular hole, have lifting unit spare below rectangular hole, lifting unit spare is pushing up cleans the spool, when lifting unit spare raises, cleans the contact of spool and coiled material, when lifting unit spare descends, clean spool and coiled material and separate, lifting unit spare still connect electric actuator, electric actuator connection control device, such electric blackboard have that the optional is cleaned, convenient to use's advantage, lifting unit spare still connect electric actuator, the electric actuator connection control device still has control and cleans more convenient advantage.
Description
Technical field
The utility model relates to realia, specifically relates to driven blackboard.
Background technology
Driven blackboard comprises framework, has upper winding shaft and lower winding shaft in framework, also has the coiled material of annular to be enclosed between upper winding shaft and lower winding shaft, and also have and its wiping spool be arranged in parallel in the outside of described upper winding shaft or lower winding shaft, wiping spool is arranged in framework; In prior art, wiping spool is fixed in framework, and that is, always and cylinder contacts, like this, wiping spool just always wipes out the writing on coiled material to wiping spool, but does not in use sometimes need writing to wipe, and has awkward shortcoming.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of driven blackboard of the easy to use wiping selected.
The technical solution of the utility model is achieved in that the driven blackboard can selecting wiping, comprise framework, upper winding shaft and lower winding shaft is had in framework, the coiled material of annular is also had to be enclosed between upper winding shaft and lower winding shaft, in the outside of described lower winding shaft also have and its wiping spool be arranged in parallel in framework, it is characterized in that: described framework side has length strip hole setting up and down, described wiping spool is arranged in strip hole, Lift Part is had below strip hole, Lift Part heads on wiping spool, when Lift Part rises, wiping spool and cylinder contacts, when Lift Part declines, wiping spool is separated with coiled material.
Say further, described Lift Part also connects electric device, electric device connection control device.
The beneficial effects of the utility model are: such driven blackboard has can select wiping, advantage easy to use; Described Lift Part also connects electric device, electric device connection control device, also has and controls wiping advantage more easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, framework 2, upper winding shaft 3, lower winding shaft 4, coiled material 5, wiping spool 6, strip hole 7, Lift Part.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the driven blackboard of wiping can be selected, comprise framework 1, upper winding shaft 2 and lower winding shaft 3 is had in framework, the coiled material 4 of annular is also had to be enclosed between upper winding shaft and lower winding shaft, in the outside of described lower winding shaft also have and its wiping spool 5 be arranged in parallel in framework, it is characterized in that: described framework side has length strip hole setting up and down 6, described wiping spool is arranged in strip hole, Lift Part 7 is had below strip hole, Lift Part heads on wiping spool, when Lift Part rises, wiping spool and cylinder contacts, when Lift Part declines, wiping spool is separated with coiled material.
When needs wiping, Lift Part rises, wiping spool and cylinder contacts, and when not needing wiping, Lift Part declines, and wiping spool and coiled material depart from, and can realize the purpose of this utility model.
Say further, described Lift Part also connects electric device, electric device connection control device.Such control button just can realize the effect rotating wiping, more saves labour.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed in the scope of the claims of the present utility model.
