Abstract

A windproof sunshade comprises an umbrella fabric, an umbrella stand and an upright pole used for supporting, wherein the umbrella fabric is covered on the umbrella stand, the umbrella stand comprises a plurality of long ribs, a plurality of short ribs and a central pole, an upper umbrella tray for connecting the long ribs and a lower umbrella tray for connecting the short ribs are arranged on the central pole, and the long ribs and the short ribs can fold up or expand relative to the central pole. The windproof sunshade is characterized in that each long rib is formed by an upper rib and a lower rib connected in a foldable way, and the lower rib can turn over upwards under the action of wind force. When the sunshade runs into heavy wind, the lower ribs turn over upwards, so the wind force is prevented from completely transferring to the umbrella ribs, the umbrella ribs cannot be fractured or turned over, and the windproof capability of the sunshade is greatly improved. The windproof sunshade has the characteristics of simple structure, convenience in operation and strong practicality, and is also lower in manufacturing cost.

Description

A kind of blast screen sunshade

Technical field

Summary of the invention

The utility model technical problem to be solved is to the above-mentioned state of the art a kind of blast screen sunshade to be provided; This parasols is designed to folding go up bone and sending down the fishbone with long bone; When running into strong wind; Sending down the fishbone can upwards turn down with this and dredge wind-force, avoids fractureing of umbrella frame, has the good characteristics of performance simple in structure, easy to operate, windproof.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of blast screen sunshade; Comprise umbrella cover, umbrella stand and the vertical rod that is used to support; Said umbrella cover is covered on the umbrella stand; Said umbrella stand comprises a plurality of long bones, a plurality of short bone and a center-pole, on center-pole, is provided with the upper umbrella disc and the following umbrella disk that is used to be connected short bone that are used to connect long bone, and said long bone and short bone can be packed up or opened with respect to center-pole; It is characterized in that: said long bone is to be formed by connecting in last bone and sending down the fishbone collapsiblely, and sending down the fishbone can upwards turn down under the effect that receives wind-force.

As improvement, a said end of going up bone is installed on the upper umbrella disc, and the other end is connected with the middle and upper part of sending down the fishbone through connector rotationally, and the sidepiece of bone is provided with spacing block above the head position with respect to sending down the fishbone on said.

As improvement; Said block is rectangular

shape of cross section; Form the flanging of outside turnover in the inboard, lower end of block; Have through hole on the flanging, be fixed on the sidepiece of bone, when the said bone of going up is connected through screw or rivet with sending down the fishbone rotationally through screw; And go up bone and sending down the fishbone when in alignment when said, the head of said sending down the fishbone just in time is limited in the place, right angle of block.

Improve, an end of said short bone is installed in down on the umbrella disk again, and the other end is connected fixing with the middle and lower part of sending down the fishbone rotationally.

As improvement, said down umbrella disk can slide up and down to be nested with on center-pole, above umbrella disk down, the centre position of center-pole is fixed with a spacing collar.

At last, said bone and folding long bone of sending down the fishbone composition gone up, through interconnecting of upper umbrella disc, center-pole, following umbrella disk and short bone, forming a cross section is leg-of-mutton folding umbrella stand, when wind was big, sending down the fishbone can upwards turn down.

Compared with prior art; The advantage of the utility model is: long bone is designed to folding upward bone and sending down the fishbone, and sending down the fishbone upwards turnover only, like this when parasols runs into strong wind; Sending down the fishbone is turnover upwards; Avoid wind-force all to pass on the umbrella frame, and can umbrella frame not fractureed or overturning, improved the wind loading rating of parasols greatly.The utlity model has simple in structure, easy to operate, practical characteristics, manufacturing cost is also lower simultaneously.
