Umbrella Capable of Being Quickly Assembled and Disassembled

An umbrella capable of being quickly assembled and disassembled, comprising:

• a column;
• a plurality of long rods each having a middle portion;
• a plurality of short rods;
• an upper nest;
• a lower nest;
• a plurality of rod connectors each having a rear end and a front end;
• a plurality of connecting mechanisms;
• wherein,
• each long rod has a first end which is detachably connected to the upper nest through one rod connector, and each short rod has a first end which is detachably connected to the lower nest through one rod connector and a second end which is detachably connected to the middle portion of the corresponding long rod through one connecting mechanism;
• each of the upper nest and the lower nest has a plurality of connecting grooves formed at intervals on a periphery of the upper nest and the lower nest, each connecting groove is for receiving one rod connector and has two inner walls, each of the upper nest and the lower nest has a plurality of pairs of connecting pins each pair protruding from two inner walls of the corresponding connecting groove;
• the rear end of each rod connector is connected to one long rod or one short rod, each rod connector has two sliding grooves respectively formed at a left side and a right side of the front end of each rod connector for receiving the pair of connecting pins, each sliding groove is distributed inclined and has an opening;
• when the front end of each rod connector is inserted into the corresponding connecting groove of the upper nest or the lower nest at a certain angle, each pair of connecting pins is capable of inserting into the corresponding two sliding grooves passing through the corresponding openings after rotating the rod connector, so as to make the rod connector quickly connect to the upper nest and the lower nest.
