Large-size lightbox ball

Abstract

The invention relates to a large-size lightbox ball, comprising a ball body, a support and an inflating device, wherein the ball body is made by clipping a high-strength composite flexible material according to a special spherical surface and then splicing the clipped materials; the support is arranged at the lower part of the ball body and comprises a bottom ring, a bottom beam, a first stand column, a second stand column, a third stand column, a strut, a tying ring and a top ring; and the inflating device is arranged on the support. Compared with the prior art, the large-size lightbox ball disclosed by the invention has the advantages of large spherical angle, a wider information propagation range, high integral lateral stability and wind resistance of a ball body structure, longer service life, and capability of reducing the consumed energy for compensating air pressure losses, and the support can be designed into different shapes according to the requirements on activity styles on the premise of preserving a consistent top ring form.

Description

technical field [0001] The invention relates to an advertising prop, in particular to a large light box ball. Background technique [0002] Currently, inflatable structures with a spherical appearance are favored in advertising campaigns. But there are mainly the following problems: [0003] (1) The stability of the small structure is poor, and it will deform significantly under the action of wind, making the structure easy to damage, especially not suitable for outdoor use; [0004] (2) The spherical area of ​​the small structure is small, which is not conducive to the transmission of information in large-scale activities; [0005] (3) The overall height of the large-scale structure is relatively short, resulting in a single appearance of the sphere, generally a hemisphere or a spherical cap smaller than a hemisphere; due to its small spherical angle, the range of directions for transmitting information is not as good as that of small structures; [0006] (4) The passage...

AI Technical Summary

Problems solved by technology

[0003] (1) The stability of the small structure is poor, and it will deform significantly under the action of wind, making the structure easy to damage, especially not suitable for outdoor use;

[0004] (2) The spherical area of ​​the small structure is small, which is not conducive to the transmission of information in large-scale activities;

[0005] (3) The overall height of the large-scale structure is relatively short, resulting in a single appearance of the sphere, generally a hemisphere or a spherical cap smaller than a hemisphere; due to its small spherical angle, the range of directions for transmitting information is not as good as that of small structures;

[0006] (4) The passages that generally need to be configured for large-scale structures will bring additional air pressure loss to the inflatable structure, so that large-scale structures need to consume more energy to maintain structural stability;

[0007] (5) When disassembling a large inflatable structure, it is easy to cause dirt and damage to the spherical material, shortening the normal service life of the structure;

This is a major inconvenience for events of longer duration
