Description

TECHNICAL FIELD

[0001] The utility model relates to a component of an umbrella used in daily life, in particular to a structure improvement of a hanging and unhooking device of an umbrella movable nest, and is suitable for various multi-fold umbrellas or straight bone umbrellas. BACKGROUND

[0002] The existing push-pull type umbrella nest is sleeved with a sleeve that can slide up and down on the lower nest main body of the umbrella, and the lower nest can be hung or unhooked at the umbrella opening position by pushing or pulling the sleeve, which is very convenient to use. Some push-pull type umbrella nests include a ring nest body for connecting with the umbrella ribs and a sleeve that is slidably sleeved below the ring nest body, an elastic sheet extending upward is arranged on the upper part of the ring nest body, and a pull sheet extending upward is arranged on the top of the sleeve and located inside the elastic sheet. When the sleeve is pushed upward to the upper part inside the elastic sheet of the ring nest body and hung at the hanging point arranged on the side wall of the upper nest of the umbrella, the protrusion arranged inside the pull sheet is clamped into the recess arranged on the side wall of the upper nest, and at this time, the lower nest can be hung at the umbrella opening state. When the sleeve is pulled downward, the protrusion inside the pull sheet slides out of the recess of the upper nest through the bottom guide surface and pushes the elastic sheet outward, so that the top of the elastic sheet moves outward and is separated from the hanging point of the upper nest, and at this time, the lower nest is unhooked and can be moved downward to close the umbrella. This umbrella nest structure does not need to open a hole in the side wall of the middle rod of the umbrella, and will not damage the strength of the middle rod. However, in the process of hanging and unhooking the lower nest, the protrusion inside the elastic sheet needs to pass through a long stroke from the bottom of the upper nest to the recess of the side wall of the upper nest, so that the force required to push and pull the lower nest sleeve to open and close the umbrella is heavy and not smooth, and the elastic sheet is forced to move outward whether the lower nest is hung or unhooked, which is easy to damage, thereby affecting the service life of the umbrella. SUMMARY

[0003] The utility model solves the technical problem of providing a hanging and unhooking device of an umbrella nest body, which is easy to push and pull smoothly and saves effort when opening and closing the umbrella.
