Wind inlet-adjustable windproof umbrella

Abstract

The invention discloses a weatherproof umbrella with an adjustable air inlet, which comprises an umbrella handle, a fixed-angle rib, a fixed-angle umbrella surface, a windproof adjustable rib and a windproof umbrella surface; the upper end of the umbrella handle is screwed with a top cover from top to bottom and a hinged seat; the umbrella handle is provided with a fixed-angle open and closed ring and a windproof open-close ring; the fixed-angle umbrella frame includes a number of fixed-angle inner support rods and a number of fixed-angle outer support rods; the fixed-angle umbrella surface is set on the fixed-angle outer support rod On the outer side wall and at the bottom of the fixed angle outer support bar; the windproof adjustment ribs include some windproof inner support bars and some windproof outer support bars; the windproof umbrella surface is arranged on the outer side wall of the windproof outer support bar; the lower end of the windproof umbrella surface is high On the upper end of the fixed-angle umbrella surface; a cylindrical groove-shaped sliding groove is set inside the umbrella handle; a fixed-angle opening and closing ring limiting device and a windproof opening and closing ring limiting device are arranged in the sliding groove. The gap between the windproof umbrella surface and the fixed angle umbrella surface of the present invention can be adjusted, and can be applied to windy weather of different grades.

Description

[0001] Technical field: [0002] The invention relates to the technical field of rain gear, in particular to a weatherproof umbrella with an adjustable air inlet. Background technique [0003] In summer, there are often strong winds and heavy rains. At this time, the umbrellas will be turned over by the strong winds and become trumpet umbrellas, and people will be wet by the heavy rain. The solution is to offer through holes on the umbrella surface so that the air inside and outside the umbrella surface can penetrate, so that the umbrella surface can remove the force of the wind. But if the wind force is very strong, the through hole must be very large to unload the force in time. However, if the through hole is too large, it cannot play the role of keeping out the rain; therefore, it is necessary to be able to adjust the amount of air intake, so as to be suitable for weather with different wind forces. Contents of the invention [0004] The object of the present invention...
