Description
Technical field
The present invention relates to teaching equipment field, in particular to a kind of deformable blackboard.
Background technique
Blackboard is the plane that can use chalk repeated writing, and plate face is hard, is chiefly used in imparting knowledge to students.Blackboard generally uses plank
Or made of ground glass etc., it can be write with the specific writing material such as chalk above.It is universal due to multimedia teaching,
The extensive use of computer and projector, space utilization rate is very high in present classroom, and many blackboards are designed to defecate very much
Be easy to be in the way, and blackboard is designed too small, sometimes again it is not enough come written contents.Existing blackboard design is simple, can not be certainly
By neatly changing volume, be not suitable for using in multi-media classroom.
Summary of the invention
It is ingenious in design technical problem to be solved by the invention is to provide a kind of deformable blackboard, it can with freedom and flexibility
Change volume, acts freely, it is highly reliable, it is suitble to use in multi-media classroom.
To achieve the above object, the present invention provides technical solution below:
The deformable blackboard includes the fixation blackboard of rectangular plate-like, and fixed blackboard side is provided with the pumping slot of rectangle, fixed black
The bottom that plate is provided with pumping slot side is vertically equipped with backing, and fixed blackboard be not provided with pumping slot three layers are enclosed with fixed border, Gu
Deckle arch is vertically equipped with the hanging ring of two annulars, and the Reelable blackboard of rectangular plate-like is inserted in the pumping slot of fixed blackboard, and activity is black
Plate side is enclosed with active border, and active border is vertically equipped with knob at the pumping slot side center far from fixed blackboard.
Preferably, the fixed blackboard, Reelable blackboard, backing are manufactured by hard PVC, and fixed blackboard and backing are
Overall structure, fixed blackboard and Reelable blackboard surface are brushed with blackboard paint.
Preferably, the fixed border and hanging ring are manufactured from aluminum alloy, and fixed border and hanging ring pass through welded connecting, Gu
Deckle frame is connect by screw with fixed blackboard.
Preferably, the active border and knob are manufactured from aluminum alloy, and active border and knob are living by being welded to connect
Dynamic frame is connect by screw with Reelable blackboard.
Preferably, the pumping slot clearance fit of the Reelable blackboard and active border and fixed blackboard.
Be using the beneficial effect of above technical scheme: the deformable blackboard can pass through hanging ring by nail during installation
The suitable position of classroom metope is hammered into fix fixed blackboard.Reelable blackboard can be inserted into the pumping slot of fixed blackboard by user
It is interior, knob can also be held by Reelable blackboard and pull out appropriate length out of fixed blackboard pumping slot, to flexibly change blackboard
Volume, for using.The deformable blackboard is ingenious in design, can with freedom and flexibility change volume, act freely, highly reliable,
It is suitble to use in multi-media classroom.
Detailed description of the invention
A specific embodiment of the invention is described in further detail with reference to the accompanying drawing.
Fig. 1 is a kind of main view of deformable blackboard of the present invention；
Fig. 2 is a kind of left view of deformable blackboard of the present invention.
Wherein, the fixed blackboard of 1-, 2- Reelable blackboard, 3- backing, 4- fixed border, 5- active border, 6- knob, 7- are hung
Ring, 8- pumping slot.
Specific embodiment
A kind of preferred embodiment of deformable blackboard that the invention will now be described in detail with reference to the accompanying drawings.
Show a kind of specific embodiment of deformable blackboard of the present invention in conjunction with Fig. 1 and Fig. 2:
The deformable blackboard includes the fixation blackboard 1 of rectangular plate-like combined with Figure 1 and Figure 2, and fixed 1 side of blackboard is provided with square
The pumping slot 8 of shape, the bottom that fixed blackboard 1 is provided with 8 side of pumping slot are vertically equipped with backing 3, and fixed blackboard 1 is not provided with the three of pumping slot 8
Layer is enclosed with fixed border 4, and 4 top of fixed border is vertically equipped with the hanging ring 7 of two annulars, is inserted in the pumping slot 8 of fixed blackboard 1
The Reelable blackboard 2 of rectangular plate-like, 2 side of Reelable blackboard are enclosed with active border 5, pumping of the active border 5 far from fixed blackboard 1
Slot is vertically equipped with knob 6 at 8 side center.The length of backing 3 is equal to the length of Reelable blackboard 2, and it is black that backing 3 can hold up activity
Plate 2.
Fixed blackboard 1, Reelable blackboard 2, backing 3 are manufactured by hard PVC, and durable, lighter in weight, cost is just
Preferably, fixed blackboard 1 and backing 3 are overall structure, and fixed blackboard 1 and 2 surface of Reelable blackboard are brushed with blackboard paint, so as to
Chalk writes on fixed blackboard 1 and Reelable blackboard 2.Fixed border 4 and hanging ring 7 are manufactured from aluminum alloy, sturdy and durable, corrosion resistant
Lose functional, by being welded to connect, fixed border 4 is connect by screw with fixation blackboard 1 for fixed border 4 and hanging ring 7.Activity
Frame 5 and knob 6 are manufactured from aluminum alloy, and sturdy and durable, corrosion resistance is good, and active border 5 and knob 6 are connected by welding
It connects, active border 5 is connect by screw with Reelable blackboard 2.Between Reelable blackboard 2 and active border 5 and the pumping slot 8 of fixed blackboard 1
Gap cooperation.
The deformable blackboard can pass through hanging ring 7 by nail during installation and hammer into the suitable position of classroom metope to fix
Blackboard 1 is fixed well.Reelable blackboard 2 can be inserted into the pumping slot 8 of fixed blackboard 1 by user, and can also hold knob 6 will be movable
Blackboard 2 pulls out appropriate length out of fixed blackboard 1 pumping slot 8, to change the volume of blackboard, flexibly for using.And it is movable
