Problems solved by technology

[0002] Straight bone umbrellas usually include an umbrella surface, umbrella ribs, a middle stick and an umbrella handle. Two elastic bows are installed up and down inside the middle stick. The nest squeezes the elastic bow by pushing the lower nest, and the position of opening and closing the umbrella nest is limited by the elastic bow. The existing umbrella usually uses two bows to lock the opening and closing of the umbrella. However, this kind of double limb structure requires two corresponding limb grooves on the center rod, which will destroy the strength of the entire limb, and usually directly pushes the umbrella nest, and the operation stroke of the user's arm to open and close the umbrella is longer. Moreover, the two bow limbs pass through the side wall of the middle stick, and if they leak outside, they will easily collide with the human body and cause damage to the human body.

Abstract

The invention discloses a quick and labor-saving unfolding and folding device of an umbrella. The quick and labor-saving unfolding and folding device of the umbrella comprises a middle rod. The middlerod is sleeved with a lower nest connected with umbrella ribs. An elastic arch piece is installed in the middle of the middle rod. The lower end of the lower nest is fixedly connected with a lengthened pushing rod. An unfolding and folding structure is installed at the lower part of the lengthened pushing rod and comprises a limiting barrel and a pushing disc, the limiting barrel is fixed to thelower end of the lengthened pushing rod, the pushing disc is arranged on the limiting barrel in a sleeving mode and is in sliding fit with the limiting barrel, and the lower end of the pushing disc isconnected with an arch piece barrel. According to the quick and labor-saving unfolding and folding device of the umbrella, the operation length of the arms of a user is reduced by means of the lengthened pushing rod and the unfolding and folding structure, more labor is saved during use, and convenience is brought during use.
