<p>A parasol comprises an upper parasol disc, a lower parasol disc, a long parasol frame and a short parasol frame, wherein the upper parasol disc and the long parasol frame are rotatably hinged together, one end of the short parasol frame hinges with the lower parasol disc, and the other end of the short parasol frame hinges with the upper portion of the long parasol frame to form a parasol frame. The parasol is characterized in that the upper parasol disc and the lower parasol disc are connected through inner pipes and outer pipes, and a plurality of recessed surfaces are formed on the inner pipes. Correspondingly, the outer pipes are arranged on the recessed surfaces in such a manner that the outer pipes are slidable up and down relative to the inner pipes. The upper parasol disc is fixed on the top of the outer pipes, and the lower parasol disc detachably wraps up the outer pipe and the inner pipe and is fixed to the upper portions of the inner pipes through fixing members. The lower portions of the outer pipes are connected to fixing sleeves for positioning the outer pipes, and locking structures are arranged on the positioning portions of the outer pipes. Such a structure facilitates coloring, and the parasol is more solid for connection, longer in service lifetime. The locking structures are ingenious and have positioning and locking functions, and safe holes on a fixing base ensures safe buckling.</p> |
