Handle, which is equipped with, refers to hole, and the blackboard one end is equipped with the humidifier one for precipitating dust, and the sliding rail upper end is also sliding
Dynamic connection blackboard two, two end of blackboard are equipped with the handle of push-and-pull, and two end of blackboard is equipped with the humidification for precipitating dust
Device two, described two humidifiers can be slided in blackboard one, two end of blackboard respectively, and the backboard end is equipped with for receiving
Collect the dust slot of dust, the dust slot end is equipped with the chalk holder for holding chalk, inlays and be equipped in the backboard
For the blank of projection teaching, limited block is equipped on the inside of the backboard, the limited block end is equipped with for fixing blackboard
Lock.
This practicality provide technological merit be：Blackboard can commonly be pushed and pulled by being different from, and make push-and-pull blackboard into two pieces, and
The blank using projection painting canvas can be pushed open, can be combined when not in use, and two Sliding blackboards can be fixed by lock
Position, prevent from writing inconvenience in use, in order to ensure the occupational disease that teacher can cause in use, set up
Task equipment humidifier, dust can be effectively adsorbed in by humidifier, and the quality for aggravating dust can be effectively adsorbed in blackboard
Or fall within dust slot.
As an improvement, the backboard quadrangle is round and smooth chamfering, end frame is structural al alloy, in the backboard
Side both ends are equipped with the sliding rail for sliding, and the blackboard one, two end of blackboard are equipped with the idler wheel for sliding, described
Idler wheel is equipped with adjusting block, and the blackboard one, two end of blackboard are equipped with theftproof block, and blackboard normal service life is limited when long
Between the time limit that uses blackboard and backboard when reach certain the excessive position at this time needing to adjust entire blackboard in gap, this
When adjusting block play facility.
As an improvement, being equipped with the dust-proof layer for filtering, the dust-proof layer in the humidifier one, humidifier two
Have two layers, the humidifier end electric connection of power supply, rubber leather hose connects water tank, and humidifier can not only make room air
It is improved, on the dust of environmentally-friendly sanitary, also having certain effect and then protecting, student and teacher's is healthy and safe.
As an improvement, one blackboard of blackboard, two surface, which is equipped with, is used for irreflexive frosted layer, the frosted layer
It is pasted onto blackboard surface for water white transparency layer, traditional blackboard surface is excessively smooth to lead to difference when light source direct projection is on blackboard
Position can be appreciated that reflective, so that student can't see the content on blackboard, diffusing reflection can be become by mirror-reflection by adding frosted layer
Improve ornamental.
As an improvement, the limited block is equipped with lockhole, the quantity of lockhole is two, the lockhole position and lock
Position matches.
As an improvement, being threadedly coupled anticollision pearl, the blackboard one, blackboard close to extreme on the inside of the backboard
Two ends are equipped with the anticollision pearl for anticollision, and the quantity of the anticollision pearl is at least six, adds anticollision pearl, can not only subtract
Noise of the small blackboard in collision process, moreover it is possible to be effectively increased the service life of blackboard.
