Description

Technical Field

[0001] The utility model relates to the technical field of umbrella accessories, in particular to a self-locking direction-adjusting mechanism for a parasol. Background Art

[0002] Parasols are daily tools for sheltering from the wind, rain, and sun. To fully meet the requirements of sun and rain protection, most parasols on the market have a directional adjustment function. Specifically, in order to facilitate the adjustment of the direction of the parasol, it is common practice to install an angle adjustment mechanism between the handle and the pole. This allows the angle of the parasol to be adjusted according to the angle of the sun, thereby reducing sunlight exposure. For example, a Chinese patent for a fishing umbrella steering adjustment accessory, Publication No.: CN221129059U, cooperates with the locking portion on the locking member and the steering portion of the steering portion. At the same time, under the squeezing action of the elastic force of the elastic element, the fishing umbrella handle can be tilted and adjusted along the steering axis and the angle can be fixed. However, the disadvantage of this patent is that it has too many parts, which will increase the complexity of production and manufacturing, making the production cost high. Therefore, how to simplify the structure of the steering mechanism while ensuring its function to reduce production costs is the issue to be explored in this application. Utility Model Content
