Folding umbrella with controllable shielding area based on pc plastic glass fiber cloth

Abstract

The invention discloses a folding umbrella with a controllable shielding area based on pc plastic glass fiber cloth. By arranging a transmission rod, a threaded rod, a base, a first connecting ring, a second connecting ring and a clamping ring, when in used, a separation block drives the position of the base to change; when the position of the base changes, the position of the top end of a first framework synchronously deviates; under the condition that the supporting positions of a second framework and a third framework are not changed, the supporting strength of the first framework is changed; when wind power is large, the wind resistance effect is improved by enhancing the supporting strength of the first framework; and meanwhile, in the sun shading process, the compactness of the first framework is reduced by reversely rotating a threaded sleeve, so that the shielding cloth is kept in a loose state, the opening degree gets smaller, and the coverage on the head is increased. By means of the mode, the wind resistance strength for different environments can be adjusted according to use, meanwhile, the opening degree can be slightly adjusted, and the umbrella is made to be suitable for use in the different environments.
