Description
Technical field
The utility model relates to a kind of folding blackboard, is specially a kind of Portable movable foldable formula blackboard.
Background technology
The main as a whole blackboard of existing mobile blackboard and two bracing frame compositions, then move by the runner of bracing frame below.Existing shortcoming is: blackboard is heavier, move and be merely able to rely on roller slip, and volume ratio is larger, cannot move at a distance easily.
The utility model is transformed on the basis of existing mobile blackboard, one monoblock of existing blackboard is designed to 4 piecemeals that connect together, then connect with hinge, can carry out it to be folded into the shape of a fritter, then bracing frame can Telescopic rotating, finally can be folded into the appearance of a luggage case, convenient delivery, laborsaving, save trouble, be convenient for carrying.Be specially:
A kind of folding blackboard, comprise the black whiteboard face of rectangle of four formed objects, these four plate faces are through folding chain connection, on the minor face of two symmetrical plate faces, be provided with jockey, jockey lower end is provided with free-extension bar, free-extension bar lower end is connected with balance base, and balance base both sides are provided with universal wheel through fixture;
The inner side minor face of plate face is provided with space arbitrarily, is also provided with telescopic bar in space, is provided with control telescopic lever and stretches out the button stretching on telescopic lever.
Described folding hinge has 6, is symmetricly set on respectively the inner side of 3 panels arbitrarily, and the outer ledge of panel being fixed between two to four plate faces is fixed through space of a whole page bar.
Described jockey is can the revolving flexible connection in front and back.
Described free-extension bar is made up of 3 section telescopic bars, and every section telescopic bar connects through the buckle of expansion link bar inner side, and from top to bottom, the diameter of expansion link reduces successively.
Advantage of the present utility model is exactly that it does not need other auxiliary equipment to consign device, easy to carry, adopts folding mode, reduces and takies volume.The pattern that is designed to luggage case can be consigned at a distance to blackboard, laborsaving, saves trouble, and saves worry.

Detailed description of the invention
embodiment 1
A kind of Portable movable foldable formula blackboard, comprise the black whiteboard face 2 of rectangle of four formed objects, these four plate faces 2 connect through folding hinge 3, on the minor face of two symmetrical plate faces 2, be provided with jockey 6, jockey 6 lower ends are provided with free-extension bar 5, free-extension bar lower end is connected with balance base 9, and balance base 9 both sides are provided with universal wheel 8 through fixture 7;
The inner side minor face of plate face 2 is provided with space 10 arbitrarily, is also provided with telescopic bar 11 in space 10, is provided with control telescopic lever 11 and stretches out the button 12 stretching on telescopic lever 11.
Described folding hinge 3 has 6, connects between two respectively the two boards face of upper left and upper right, the two boards face of lower-left and bottom right, and two the plate faces in upper right and bottom right, through figure mono-, figure bis-, finally becomes the appearance of figure tetra-after figure tri-folding.
The outer ledge of four described plate faces 4 is fixing through edge band 1.
Described jockey 6 is can the revolving flexible connection in front and back.
Described free-extension bar 5 is made up of 3 section telescopic bars, and every section telescopic bar connects through the buckle of expansion link bar inner side, and from top to bottom, the diameter of expansion link reduces successively.
operation principle:
The folding black and white plate of this Portable movable formula is mainly shown black (in vain) the plate effect of oneself, when our remote distance moving or while carrying, can folding hinge 3 be rotated by rotating the plate face 2 of left one side of something and right one side of something, allow it be folded into 1/2nd (as figure bis-), then carrying out page turning for the second time folding (as figure tri-), finally, by regulating and revolving joint, make the universal wheel direction symmetry on both sides, last adjustable telescopic rod, makes last bar cover with the condition of foot motion.
