Description
Technical field
The utility model relates to a kind of deployable and sliding blackboard, belongs to the technical field of teaching aid.
Background technology
Blackboard newspaper makes carrier with blackboard that is fixing or movement, the popularization publicity position of Writing-painting instrument is done with chalk or poster paint, there is the advantage of easy scouring, amendment, replacing, be most economical, most convenient, modal a kind of propagandizing form, be widely used in middle and primary schools, army, universities and colleges and factories and miness enterprises and institutions.
At present, all kinds of blackboard that can slide big-and-middle universities and colleges use more, be usually applicable to large-scale classroom or meeting room etc., and the similar blackboard being applicable to small-sized place is less, therefore, develop a kind of blackboard that can increase writing surface for small-sized place to be necessary very much.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of deployable and sliding blackboard, deployable collapsible, controls write area according to actual needs and can be free to slide that control is write, display location.
The utility model is achieved through the following technical solutions.
A kind of deployable and sliding blackboard, comprise mainboard, subplate, locking mechanism, two slide rails, above-mentioned mainboard is the single sided board that front can be write, above-mentioned subplate is the dual platen that tow sides all can be write, above-mentioned subplate is hinged on the top of above-mentioned mainboard, when being in non-deployed condition, above-mentioned subplate covers the front of above-mentioned mainboard, when being in deployed condition and subplate upwards dig and parallel with above-mentioned mainboard time, above-mentioned locking mechanism locks above-mentioned subplate, above-mentioned two slide rails vertically and be set in parallel in the both sides of above-mentioned mainboard and above-mentioned mainboard face is provided with vertical chute, the side of above-mentioned mainboard all arranges at least two slide bars, above-mentioned slide bar inserts the chute of above-mentioned two slide rails and coordinates with slide.
Further, above-mentioned locking mechanism comprises threaded rod, bolt, a side of the end face of above-mentioned mainboard is provided with incomplete screwed hole, the corresponding position of the side of hinged of above-mentioned subplate and the incomplete screwed hole of above-mentioned mainboard is also provided with incomplete screwed hole, when subplate is in deployed condition, the incomplete screwed hole of above-mentioned mainboard and the incomplete screwed hole of above-mentioned subplate form complete screwed hole, and above-mentioned threaded rod inserts above-mentioned screwed hole and locked by above-mentioned bolt.
Further, the width of the notch of the chute of above-mentioned slide rail is less than the width of the inner space of chute, and above-mentioned slide bar inserts the partial shape of above-mentioned chute and above-mentioned chute matches.
Further, above-mentioned slide bar has screw thread, and above-mentioned jack rod sleeve is equipped with clamping screw.
The beneficial effects of the utility model:
Can Lookup protocol write area by arranging subplate, the setting simultaneously regulated is comparatively reasonable, uses comparatively convenient, flexible; Simultaneously can free lifter slide, conveniently control the position of writing or showing, relative to comparatively large-scale Sliding blackboard, its structure seems comparatively simple and easy, the use in comparatively applicable small-sized place.
Accompanying drawing explanation
Fig. 1 is the deployable and structural representation of sliding blackboard of the implementation case.
Detailed description of the invention
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the deployable and structural representation of sliding blackboard of the implementation case, with reference to Fig. 1, , the utility model, deployable and sliding blackboard, comprise mainboard 1, subplate 2, locking mechanism, two slide rails 4, the single sided board that above-mentioned mainboard 1 can be write for front, above-mentioned subplate 2 is the dual platen that tow sides all can be write, above-mentioned subplate 2 is hinged on the top of above-mentioned mainboard 1, when being in non-deployed condition, above-mentioned subplate 2 covers the front of above-mentioned mainboard 1, when being in deployed condition and subplate 2 upwards dig and parallel with above-mentioned mainboard 1 time, above-mentioned locking mechanism locks above-mentioned subplate 2.Above-mentioned two slide rails 4 vertically and be set in parallel in the both sides of above-mentioned mainboard 1 and above-mentioned mainboard 1 face is provided with vertical chute, the side of above-mentioned mainboard 1 all arranges at least two slide bars 11, and above-mentioned slide bar 11 inserts the chute of above-mentioned two slide rails 4 and coordinates with slide.
Above-mentioned locking mechanism comprises threaded rod, bolt, a side of the end face of above-mentioned mainboard 1 is provided with incomplete screwed hole, the corresponding position of the side of hinged of above-mentioned subplate 2 and the incomplete screwed hole 10 of above-mentioned mainboard 1 is also provided with incomplete screwed hole 20, when subplate 2 is in deployed condition, the incomplete screwed hole 10 of above-mentioned mainboard 1 forms complete screwed hole with the incomplete screwed hole of above-mentioned subplate 2, and above-mentioned threaded rod inserts above-mentioned screwed hole and locked by above-mentioned bolt.
The width of the notch of the chute of above-mentioned slide rail 4 is less than the width of the inner space of chute, and above-mentioned slide bar 11 inserts the partial shape of above-mentioned chute and above-mentioned chute matches.Above-mentioned slide bar 11 has screw thread, and above-mentioned slide bar 11 is set with clamping screw 12.
