The present invention relates to the technical field of outdoor umbrellas, and particularly relates to a curved pipe umbrella with a structure for adjusting an inclination angle of an umbrella body.
Outdoor umbrellas, also referred to as sunshades, can be divided into side column umbrellas, Roman umbrellas, banana umbrellas, and the like according to models, and they are usually single-sided umbrellas. Curved arm hanging umbrellas, as sunshades with a unique model in outdoor sunshades, have a good market and better aesthetic appearance and are popular with many people.
Most curved arm hanging umbrellas use a curved pipe structure. The curved arm hanging umbrella mainly includes an upper curved pipe, a lower curved pipe, an umbrella fabric, and a base. The structure for adjusting the inclination angle of the umbrella fabric is to mount a handle and a locking device on a supporting rod of a main umbrella body. During operation, the locking device is loosened first, and then the supporting rod is manually operated to rotate left and right to control the inclination angle of the umbrella fabric. The curved arm hanging umbrella is troublesome to operate. Cooperation among parts is easily prone to problems, so that it is troublesome to adjust.
For example, a patent with publication No. CN221012246U provides a telescopic curved arm umbrella column structure for an outdoor curved arm hanging umbrella, including a lower curved pipe, an upper curved pipe, and an armrest structure. An opening is formed in a side wall of the lower curved pipe in a length direction thereof. The upper curved pipe is slidably inserted into the lower curved pipe. The armrest mechanism is arranged at a lower end of the upper curved pipe and stretches out from the opening of the lower curved pipe for people to operate, which locks the upper curved pipe on the lower curved pipe.
However, according to the curved arm hanging umbrella in the above structure, the upper and lower curved pipes need to match with the armrest mechanism to push and pull up and down for stretching. A user needs to exert a large force to push and pull the armrest mechanism. Particularly, it is strenuous to operate part of outdoor umbrellas with large umbrella body. For this kind of curved pipe hanging umbrellas, the angle of the inclined plane of the umbrella body cannot be adjusted, so that the curved pipe hanging umbrellas are relatively single in using function.

The second curved pipe umbrella column 200 is configured to match with the upper umbrella tray 520 for mounting, and the other end of the pole bracket 510 matches with the upper umbrella tray 520 for mounting.
Combined with the above, the umbrella unfolding and folding mechanism 410 is arranged in the sliding seat 400. The umbrella unfolding and folding mechanism 410 is configured to unfold or fold the umbrella body. The umbrella unfolding and folding mechanism 410 usually includes a rope winding wheel and an umbrella rope. The rope winding wheel is configured to encircle the umbrella rope to roll or loosen the umbrella rope. As the rope winding wheel rolls the umbrella rope, the umbrella stand can be unfolded. On the contrary, the umbrella stand retracts, and the other end of the umbrella rope is usually fixed with the lower umbrella tray 530 in a matched manner. A specific structure of the umbrella unfolding and folding mechanism can refer to an umbrella unfolding and folding mechanism commonly used in the Roman umbrella in the prior art.
