Abstract

The banana-shaped sunshade includes a pedestal, a support rod, a suspending rod and an umbrella fabric bracket, as well as a guide joint connected to the top of the support rod and capable of rotating horizontally, a movable seat connected movably around the support rod, and a locating seat connected to the support rod and the movable seat. The present invention has reduced rotation friction force, less wear of the rotation part, increased rotation regulating stability and lowered material cost.

Description

technical field [0001] The invention belongs to an umbrella category, in particular to a sunshade banana umbrella. Background technique [0002] Umbrellas are daily necessities used by people for outdoor entertainment and leisure to shelter from the sun and rain. Due to changes in sunlight, wind direction, scenery, hobbies and many other factors at any time, it is necessary to turn the umbrella surface horizontally to different directions to increase the number of people under the umbrella surface. The range of motion and the degree of freedom, the solution of the prior art is usually: connect the rotating disk at the base; or directly rotate the support rod movably connected with the base, and the support rod drives the umbrella surface to rotate. The cost of the former is relatively high; the latter has disadvantages such as large rotational friction resistance, easy wear and tear of the rotating parts, and unstable rotation adjustment because the support rod and the base ...
