Description

Technical Field

[0001] This utility model relates to the field of sunshade technology, and in particular to a wind-resistant sunshade. Background Technology

[0002] Existing sun umbrellas have poor wind resistance. When used outdoors, the canopy and ribs are easily flipped upwards by strong winds. Once this happens, the canopy needs to be manually flipped back to its normal position, causing significant inconvenience and affecting the user experience. Especially in sustained windy weather, the canopy may flip upwards frequently, requiring users to constantly adjust its position, which seriously affects the normal use of the sun umbrella. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a wind-resistant sunshade.

[0004] The purpose of this utility model is achieved through the following technical solution: a wind-resistant sun umbrella, including umbrella ribs and support columns, with a wind-resistant rope retraction device provided on the support columns. The wind-resistant rope retraction device includes a shell, with a plurality of rotatable spools inside the shell. A retractable wind-resistant rope is connected to the spools, with one end of the wind-resistant rope serving as the retraction end, which extends out of the shell and is used to connect to the end of the umbrella ribs. The wind-resistant rope retraction device also includes a rotating mechanism for driving the spools to rotate.

[0005] Preferably, the umbrella ribs are provided with a connecting ring at the end, and the wind-resistant rope is provided with a hook at the retraction end.

[0006] Preferably, the outer shell is annular, and the outer shell is fitted onto the support column, with the spools arranged in a circular array inside the outer shell.

[0007] Preferably, the rotating mechanism includes a rotating ring rotatably mounted on the outer casing and a gear connected to the spool, the gear being coaxial with the spool; an internal gear ring is provided on the inner side of the rotating ring, the internal gear ring meshing with the gear.

[0008] Preferably, the rotating ring includes a ring body, which is sleeved on the outside of the outer shell, and an internal toothed ring is disposed on the inside of the ring body; a retaining flap is provided at the lower end of the ring body, and a protrusion is provided on the retaining flap; an annular groove is provided on the outside of the outer shell, and the protrusion is engaged in the annular groove and can move around the annular groove.

[0009] Preferably, the rotating ring is made of plastic.

[0010] Preferably, the wind-resistant rope is made of nylon.

[0011] The beneficial effects of this invention are as follows: By installing a wind-resistant rope release device on the support column, the wind-resistant rope is fully released in windy weather, and its end is connected to the end of the umbrella rib, keeping the rope taut. The wind-resistant rope applies tension to the end of the umbrella rib, thus restraining it and effectively preventing the umbrella rib and canopy from flipping upwards, thereby improving the wind resistance of the parasol. This invention is particularly suitable for long-term use in outdoor camping, beach, and other similar scenarios, providing a superior user experience. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, a wind-resistant sun umbrella includes umbrella ribs 2 and support column 1. The support column 1 is equipped with a wind-resistant rope 5 retraction device. The wind-resistant rope 5 retraction device includes a housing 4. The housing 4 contains a plurality of rotatable spools 9. The spools 9 are connected to the wind-resistant ropes 5. One end of the wind-resistant rope 5 is the retraction end, which passes through the housing 4 and is used to connect to the end of the umbrella rib 2. The wind-resistant rope 5 retraction device also includes a rotating mechanism for driving the spools 9 to rotate.

[0019] The reason why existing parasols have poor wind resistance and are prone to flipping up is that, when the parasol is open, the ends of the umbrella ribs 2 lack effective restraint, causing the umbrella surface to flip up together when subjected to strong winds. In this invention, a wind-resistant rope 5 retraction device is installed on the support column. In windy weather, the wind-resistant rope 5 is fully released, and its end is connected to the end of the umbrella rib 2, keeping the rope taut. The wind-resistant rope 5 applies tension to the end of the umbrella rib 2, thereby restraining the end of the umbrella rib 2 and effectively preventing the umbrella ribs 2 and umbrella surface from flipping up. The wind-resistant rope 5 is retracted or extended by the rotation of the spool 9. This invention is particularly suitable for long-term use in outdoor camping, beach, and other similar scenarios, providing a superior user experience.

[0020] When the wind-resistant rope 5 is not in use (in windless weather), the rotating mechanism drives the spool 9 to rotate, which can completely wind the wind-resistant rope 5 onto the spool 9.

[0021] The outer casing 4 is provided with a rope outlet hole 4b for the wind-resistant rope 5 to pass through.

[0022] A connecting ring 3 is provided at the end of the umbrella rib 2, and a hook 6 is provided at the retraction end of the wind-resistant rope 5. The wind-resistant rope 5 is connected to the connecting ring 3 at the end of the umbrella rib 2 through the hook 6. This connection structure greatly facilitates the connection and disassembly between the wind-resistant rope 5 and the end of the umbrella rib 2.

[0023] The outer shell 4 is ring-shaped and is fitted onto the support column 1. The spools 9 are arranged in a circular array inside the outer shell 4. The outer shell 4 can slide up and down along the support column 1. There is a certain friction between the outer shell 4 and the support column 1, so that the outer shell 4 can be stably positioned on the support column 1 when no external force is applied. The sliding design of the outer shell 4 allows the entire windproof rope 5 retraction device to slide along the axial direction of the support column 1. When the sun umbrella is folded, the outer shell 4 is slid to the lower position of the support column 1 to avoid interfering with the folding of the sun umbrella. When the sun umbrella is open and the windproof rope 5 retraction device is in use, the windproof rope 5 retraction device moves to a position at the same height as the end of the umbrella rib 2.

[0024] Specifically, the rotating mechanism includes a rotating ring 8 rotatably mounted on the outer casing 4 and a gear 7 connected to the spool 9, with the gear 7 coaxially mounted with the spool 9. An internal gear ring 8b is provided on the inner side of the rotating ring 8, meshing with the gear 7. When the rotating ring 8 rotates, the internal gear ring 8b on the rotating ring 8 drives all the gears 7 to rotate synchronously, which in turn drives all the spools 9 to rotate synchronously, thereby achieving synchronous winding and unwinding of the wind-resistant ropes 5 on all the spools 9.

[0025] The rotating ring 8 includes a ring body 8a, which is fitted onto the outer side of the outer shell 4, and an internal gear ring 8b is positioned inside the ring body 8a. A retaining flap 8c is located at the lower end of the ring body 8a, and a protrusion 8d is provided on the retaining flap 8c. An annular groove 4a is provided on the outer side of the outer shell 4. The protrusion 8d engages with the annular groove 4a and can move around it. Through the cooperation between the retaining flap 8c and the annular groove 4a, the rotating ring 8 is allowed to rotate while its position is constrained, preventing it from detaching from the outer shell 4.

[0026] In this embodiment, the rotating ring 8 is made of plastic.

[0027] In this embodiment, the wind-resistant rope 5 is made of nylon. Nylon has high strength, making the wind-resistant rope 5 less prone to breakage.

[0028] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
