Description

Multi-folding umbrella rib capable of shortening folding length

Technical Field

The utility model belongs to the technical field of the skeleton of umbrella and specifically relates to a can shorten the many books rib of converting into length, it can ensure that the convenient volume of folding up back umbrella that can also reduce when folding up of umbrella.

Background

The connecting part of any supporting bone in the umbrella ribs of the existing multi-folding umbrella is formed by connecting a joint structure, but the length of the existing joint structure cannot be increased when the umbrella ribs are opened, but the existing joint structure occupies the space length when the umbrella ribs are folded, and the length of the whole umbrella in storage is influenced. That is to say, in the prior art, the folded length of the two-fold umbrella is greater than that of the three-fold umbrella, and the folded length of the three-fold umbrella is greater than that of the four-fold umbrella, so as to analogize.

In order to enable the folded length of the three-fold umbrella to be equal to the folded length of the four-fold umbrella, chinese patent document CN 108887821A discloses a folding umbrella cloth supporting rib, which comprises a first rib rod, a second rib rod and a third rib rod, wherein the first rib rod, the second rib rod and the third rib rod are sequentially hinged end to end through a hinge element to form a link mechanism which can be rotatably folded by taking a hinge point as a circle center; the first bone rod and the second bone rod are hinged in sequence, the fourth bone rod comprises an upper driven bone rod and a lower movable bone rod, the upper driven bone rod and the lower movable bone rod are sequentially hinged in sequence from head to tail, the free end of the upper driven bone rod is hinged between the first bone rod and the second bone rod, and a single-axis point double-parallel scissors type structure is formed. The lower movable bone rod is hinged to the middle of the first bone rod and is formed by matching with the free end of the first bone rod. The utility model discloses the scissors formula transmission of the two parallels of single axis point is utilized in structural research and development of rib, effectively shortens the length when first and second bone pole hinge department fold condition, and then makes the rib that has this umbrella cloth support bone under the prerequisite of guaranteeing to possess effective umbrella face usable floor area equally, and the length of accomodating after the shrink effectively shortens.

Although the structure can only have the length of a four-fold umbrella after the three-fold umbrella is folded, the parallelogram structure adopted by the umbrella ribs has the problems that the umbrella ribs are unstable and easy to swing when the umbrella is folded, and the anti-turnover capacity of the umbrella tail ribs is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above problems and provides a multi-fold umbrella rib which has stable structure, does not swing, has good anti-folding capability of the umbrella tail rib and can shorten the folding length when the umbrella is folded.

The technical scheme of the utility model realizes being: a multi-fold umbrella rib capable of shortening the folding length comprises a tail rib and at least one umbrella rib, wherein the multi-fold umbrella rib is hinged with the upper end of the tail rib through a first hinge; the utility model discloses still include movable rib, movable rib's lower pot head is in on the tailbone, with the tailbone is sliding connection, movable rib be close to upper end department with first rib be close to first articulated elements department and pass through the second articulated elements articulated, make first rib with movable rib forms scissors fork structure, simultaneously, makes the tailbone first rib with movable rib constitutes the triangle-shaped structure when receiving the umbrella, constitutes a font structure when the umbrella struts.

As an improvement of the utility model, the upper end of the movable umbrella rib is hinged with the elastic wire.

As an improvement to the present invention, the movable umbrella ribs include a first connecting piece and a second connecting piece, which are arranged in parallel, and the first umbrella ribs are sandwiched between the first connecting piece and the second connecting piece, and the lower ends of the first connecting piece and the second connecting piece are sleeved on the tailbone through a sleeve.

As an improvement to the present invention, the movable umbrella rib comprises a first connecting piece, the lower end of the first connecting piece is sleeved on the tail rib through a sleeve, the umbrella is folded in, and the first connecting piece is completely overlapped with the first umbrella rib.

As an improvement of the utility model, the lower end of the coccyx is provided with a coccyx head.

As an improvement of the utility model, the upper end of the first umbrella rib is provided with a connecting piece.

The utility model discloses owing to increased movable rib, just movable rib's lower pot head is in on the tailbone, with the tailbone is sliding connection, movable rib be close to upper end department with first rib be close to first articulated elements department and pass through the second articulated elements articulated, make first rib with movable rib forms scissors fork structure, simultaneously, makes the tailbone first rib with movable rib constitutes the triangle-shaped structure when receiving the umbrella, constitutes a font structure when the umbrella struts. Therefore, when the umbrella is folded, the umbrella ribs can be more stable when the umbrella is folded by using the stability of the triangle due to the existence of the triangle structure; because the structure that the lower end of the movable umbrella rib is sleeved on the tail bone is adopted, the movable umbrella rib can effectively support the tail bone, and the wind-proof capability of the tail bone can be enhanced.
