Stepless telescopic giant folding umbrella

Abstract

The invention discloses a stepless telescopic giant folding umbrella. Comprising a stand column body, a telescopic stand column capable of being inserted into the top end of the stand column body in an axial sliding and telescopic mode, a driving mechanism arranged in an inner cavity of the stand column body and used for driving the telescopic stand column to move in the axial direction, and connecting rod umbrella rib mechanisms connected between the telescopic stand column and the stand column body and distributed in the annular direction. The main umbrella cloth is attached to the bottom face of the connecting rod umbrella rib mechanism and annularly sleeves the outer wall of the stand column body, and the telescopic stand column drives the connecting rod umbrella rib mechanism to conduct folding or unfolding movement in the annular direction in the telescopic stroke. According to the stepless telescopic giant folding umbrella disclosed by the invention, the telescopic stand column is driven by the driving mechanism to move, and the connecting rod umbrella rib mechanism is driven to perform connecting rod transmission through the vertical lifting motion of the telescopic stand column, so that the main umbrella cloth can be conveniently folded or unfolded in the annular direction, and therefore, sun and rain can be shielded for a user after the main umbrella cloth is unfolded; or the umbrella can be folded in windy weather, so that the wind resistance of the umbrella body is improved.

Description

technical field [0001] The invention relates to the technical field of giant umbrellas, in particular to a stepless telescopic giant folding umbrella. Background technique [0002] With the development of society, some square parks, patios between shopping malls, open-air stadiums, open-air construction sites, and even archaeological work have problems such as too many people or the environment needs to be isolated from direct sunlight and rain. In these scenes, strong sunlight and rain All have had a huge impact on the travel and work of the crowd, and it is necessary to take protective measures for these people to prevent them from being affected by the sun, rain and even other bad weather. [0003] At present, giant umbrellas are usually built in open-air construction sites and other places. The giant umbrella is a temporary construction umbrella. Its rib is not supported by fixed rods, and only relies on rope support for traction, and the rib can only be rotated and cann...

AI Technical Summary

Problems solved by technology

[0003] At present, giant umbrellas are usually built in places such as open-air construction sites. This giant umbrella is a temporary construction umbrella. Its ribs are not supported by fixed rods and are only supported by ropes for traction, and the ribs can only rotate and cannot be folded.

When the ribs shrink, the height of the umbrella in the contracted state will be higher than that in the expanded state by about one frame height, which not only increases the overall height, but also leads to poor strength of the overall structure, and there are obvious defects in wind resistance

In addition, there are some beach parasols in the prior art. Although the umbrella cloth can be folded, it needs to pull two connecting rods and a spring mechanism by manpower to assist in closing and opening the umbrella, which is limited by manpower and the operation process is inconvenient. And the process is cumbersome and requires a lot of physical strength
