[0049] In another embodiment, the umbrella rib assembly may also adopt the umbrella rib assembly structure disclosed in patents CN216089262U and CN113519994A.

[0050] Continuing to refer to Figure 7, the protective wall 200 includes an anti-collision strip 2000, a protective wall head 2001, a protective wall metal cover 2002, a protective wall support 2003 and a protective wall tail 2004. The protective wall metal cover 2002 is the main structure of the protective wall 200, with the protective wall head 2001 set at one end and the protective wall tail 2004 set at the other end. A number of protective wall supports 2003 are arranged at intervals on the back side of the protective wall metal cover 2002 (when the outdoor large umbrella is folded, the side of the protective wall metal cover 2002 facing the umbrella column assembly 1), and anti-collision strips 2000 are set on the left and right sides of the protective wall metal cover 2002.

[0051] Continuing to refer to Figures 5 and 8, this embodiment also includes a drainage system 4, which includes a rainwater collector 400 and a drainage pipe assembly 401. The rainwater collector 400 is sleeved on the outer umbrella column 101 and is located lower than the lower umbrella plate 104. Its lower part is a funnel-shaped structure and its upper part is a cylindrical structure. The top edge of the funnel-shaped structure is connected to the umbrella cloth 3, and the accumulated water on the umbrella cloth 3 flows into the funnel-shaped structure. The drainage pipe assembly 401 is vertically arranged on one side of the outer umbrella column 101, and its upper end is conductively connected to the funnel-shaped structure of the rainwater collector 400. Its bottom extends into the base 6, and its bottom has a drain outlet, through which rainwater is discharged from the bottom of the base 6.

[0052] Continuing to refer to Figures 9 to 11, the umbrella fabric 3 is connected to the umbrella rib assembly through the buckle assembly 5. The buckle assembly 5 includes a locking and adjusting buckle 502, a fixing buckle 504 and a buckle 503. The locking and adjusting buckle 502 has a fixing portion and a locking portion. The fixing buckle 504 is provided on one of the umbrella rib assembly and the umbrella fabric 3, and the buckle 503 is connected to the other. A first end of the buckle 503 is connected to the fixing portion of the locking and adjusting buckle 502, and a second end of the buckle 503 passes through the fixing buckle 504 and is connected to the locking portion of the locking and adjusting buckle 502, so that the buckle 503 and the locking and adjusting buckle 502 form an annular structure, and the second end of the buckle 503 extends from the locking portion for human operation. The locking portion is used to lock the buckle 503. When the locking portion releases the buckle 503, the length of the buckle 503 extending from the locking portion can be adjusted.

[0053] It can be understood that in the above technical solution, this embodiment realizes the installation of the umbrella cloth 3 and the umbrella rib assembly through the buckle assembly 5. The buckle assembly 5 has a simple structure and the installation operation is convenient and quick without damaging the umbrella cloth 3. Moreover, the utility model can also adjust the tightness of the umbrella cloth 3 through the buckle assembly 5, which is very convenient.

[0054] 9 , the fixing buckle 504 is mounted on the long rib 204 of the rib assembly, and the buckle strap 503 is connected to the umbrella fabric 3. A plug 205 is mounted at the end of the long rib 204, and a groove 2050 is formed on the plug 205. The fixing buckle 504 is fixedly engaged with the groove 2050 by a fastener.

[0055] The buckle 503 and the umbrella cloth 3 can be connected by glue, Velcro, weaving, etc. The length of the buckle 503 used to connect with the umbrella cloth 3 is relatively large, which can improve the connection reliability.

[0056] In another embodiment, the fixing buckle 504 may be disposed on the umbrella fabric 3 , and the buckle strap 503 may be connected to the umbrella rib assembly.

[0057] Continuing to refer to FIG. 10, the fixing buckle 504 has a fixing buckle connection port 5040, and the buckle belt 503 passes through the fixing buckle connection port 5040.

[0058] Continuing to refer to FIGS. 10 and 11, the structure of the locking adjustment buckle 502 is approximately like the Chinese character 'Ri' (日). Its fixing part is the first winding rod 5020, and the buckle belt 503 is wound around the first winding rod 5020. Its locking part includes the second winding rod 5021 and the pressing rod 5022 which are arranged oppositely. The second winding rod 5021 is located between the first winding rod 5020 and the pressing rod 5022. A second locking adjustment buckle connection port is formed between the second winding rod 5021 and the first winding rod 5020, and a first locking adjustment buckle connection port 5023 is formed between the second winding rods 5021. The width of the first locking adjustment buckle connection port 5023 is smaller than that of the second locking adjustment buckle connection port. The buckle belt 503 bypasses the second winding rod 5021 and passes through the first locking adjustment buckle connection port 5023, and the pressing rod 5022 is used to press the buckle belt 503.

[0059] The installation process of the umbrella cloth 3 and the umbrella bone assembly is as follows:

[0060] When leaving the factory, the buckle belt 503 is pre-connected to the umbrella cloth 3 and connected to the first winding rod 5020. During installation, first install the fixing buckle 504 to the plug 205 through the screw 501, then pass the buckle belt 503 through the fixing buckle connection port 5040 of the fixing buckle 504, then穿入 (it should be 'pass through' in English, assume it is 'pass through') the second locking adjustment buckle connection port, bypass the second winding rod 5021, and pass out from the first locking adjustment buckle connection port 5023. Tighten the part of the buckle belt 503 that passes out from the first locking adjustment buckle connection port 5023, and press the buckle belt 503 through the pressing rod 5022 to achieve fastening. When rotating the locking adjustment buckle 502 so that the pressing rod 5022 no longer presses the buckle belt 503, the operation of adjusting the tightness of the umbrella cloth 3 or removing the umbrella cloth 3 can be carried out.

[0061] In this embodiment, the principle of the buckle belt assembly 5 is similar to that of a backpack buckle.

[0062] In this embodiment, the buckle belt assembly 5 plays a role in quickly disassembling and adjusting the tightness of the umbrella cloth on the umbrella, solving problems such as difficulty in fitting the umbrella cloth pocket, being easily punctured by the umbrella bone, and inconvenience in replacing the umbrella cloth.

[0063] The opening and closing process of the outdoor large umbrella in this embodiment is as follows:

[0064] When opening the umbrella, rotate the hand crank mechanism of the umbrella column telescopic drive mechanism 103. The umbrella column telescopic drive mechanism 103 drives the inner umbrella column 102 to move downward. The inner umbrella column 102 drives the short umbrella bone 202 to move downward and rotate. The short umbrella bone 202, the balanced long support umbrella bone 201, and the balanced short support umbrella bone 203 together drive the long umbrella bone 204 to unfold to a nearly horizontal state, thus completing the unfolding of the outdoor large umbrella; It should be noted that there is an unclear expression '穿入' in the original text, and I have made a translation assumption. If there is a more accurate expression, it can be adjusted accordingly.

[0065] When folding the umbrella, the handle mechanism of the umbrella column telescopic driving mechanism 103 is rotated, and the umbrella column telescopic driving mechanism 103 drives the inner umbrella column 102 to move upward, and the inner umbrella column 102 drives the short umbrella ribs 202 to move upward and rotate. The short umbrella ribs 202, the balanced long support umbrella ribs 201, and the balanced short support umbrella ribs 203 together drive the long umbrella ribs 204 to rotate from a nearly horizontal state to a vertical state, thereby completing the folding of the outdoor large umbrella.
