Description

Portable quick adjusting easel

Technical field

The utility model relates to a kind of improvement of easel, specifically a kind of portable quick adjusting easel.

Background technology

At present, the easel that the student goes out sketching and carries constitutes the adjustment of easel height by three interior adjusting rods, three outer tubes, adjusting pole socket, drawing board, adjusting bolts; Lean on three interior adjusting rods of pull, above-mentioned easel, though existing widespread usage, also have weak point: one is the length of three interior adjusting rods; It is consistent highly to be difficult to disposable adjustment, repeatedly the adjustment time long, speed is slow, wastes time and energy; And the pull time grown, be prone to slippage, influence drawing quality; The 2nd, the gradient of drawing board, adjusting range is little, and bad adaptability is used inconvenient.

Summary of the invention

The purpose of the utility model is to provide a kind of adjusting simple and fast, and time saving and energy saving, adaptability is strong, portably uses conveniently, improves the portable quick adjusting easel of drawing quality.

For reaching above purpose, the technical scheme that the utility model is taked is: this portable quick adjusting easel is made up of drawing board; It is characterized in that establishing hook in the back of drawing board, hook inserts in the hanging nose of universal joint front, and the internal thread of universal ball head rod is connected with the external screw thread of interior pipe upper end; The lower end of interior pipe is installed in the outer tube after connecting piston, and gas tube is located at the lower end of outer tube; And be communicated with in inflatable ball; The connecting rod upper end is connected with outer tube, and the internal thread of the external screw thread of lower end and supporting leg seat joins, and supporting leg seat lower end is established supporting leg and moved wheel.The utility model is also implemented through following measure: described universal joint; Constitute by bulb, ball rod, last bulb bowl, following bulb bowl, bellmouth, wing bolt; Ball rod is established in the lower end of bulb, after bulb is installed in the bulb bowl, the external screw thread that descends the bulb bowl is screwed in the internal thread of bulb bowl; The upper end of ball rod is movable in the bellmouth of following bulb bowl, and wing bolt contacts with bulb through the internal thread of last bulb bowl.When using the utility model to regulate height, the operation inflatable ball, inflation or venting in outer tube, pipe racks animation plate rises or descends in making, after highly suitable, the shut-down operation inflatable ball, adjustment is simple, and is time saving and energy saving; When adjustment drawing board gradient, as long as loosening wing bolt once, the push-and-pull drawing board just can obtain needed gradient, after gradient is suitable, reinforces with wing bolt again.When carrying, drawing board is taken off, interior pipe is pressed in the outer tube, backs out the supporting leg seat, puts into knapsack, carries also very convenient.

The beneficial effect of the utility model is: compare with present easel, have the adjusting simple and fast, time saving and energy saving, adaptability is strong, portably uses conveniently, improves the advantage of drawing quality.
