Description

Technical Field

[0001] This utility model relates to a wind-resistant pull rod for an umbrella, belonging to the field of umbrellas. Background Technology

[0002] Umbrellas are a common item in people's lives, often used for sunshade and to shield from rain and snow. Their structure generally includes a main pole, a ring of ribs hinged to a section of the main pole, and a stretchable waterproof fabric fixed to the ribs. However, in windy weather, the fabric of traditional umbrellas can deform, causing the ribs to bend upwards, which can lead to rib breakage or the fabric flipping up, posing a significant safety hazard.

[0003] To prevent umbrella ribs from breaking in strong winds, some umbrellas are equipped with wind-resistant structures, such as wind-resistant springs on the ribs or ribs that can be folded outwards. However, wind-resistant springs are not very effective at preventing wind damage, and folded-out ribs often result in the user getting wet in the rain, which is not a satisfactory solution. Furthermore, this design leads to complex structures or extremely high rib strength, increasing the weight and cost of the umbrella and making it less practical. Utility Model Content

[0004] In view of this, the present invention provides a wind-resistant pull rod for umbrellas to solve the problems of poor wind-resistant structure performance and complex structure in existing umbrellas.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wind-resistant pull rod for an umbrella, the umbrella including an umbrella pole, multiple umbrella ribs and a support rod connecting the umbrella pole and the multiple umbrella ribs respectively, the wind-resistant pull rod having a fixed sleeve and a movable sleeve at both ends respectively, the fixed sleeve being fitted onto the support rod and fixedly connected to the middle section of the support rod, the movable sleeve being fitted onto the umbrella ribs, the umbrella ribs having a fixing member to limit the sliding distance of the movable sleeve, and the middle section of the wind-resistant pull rod having a one-way bending structure.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the wind-resistant tie rod is an integral structure and the movable sleeve can slide along the length of the umbrella ribs, while the fixing component limits the sliding distance of the movable sleeve towards the umbrella rod. Furthermore, the wind-resistant tie rod is a flat elastic sheet with a thickened structure, and the thickened structure in the middle section is discontinuous to form a unidirectional bending structure.

[0008] Furthermore, the wind-resistant tie rod consists of two elastic rods connected axially, with the fixing component and the movable sleeve fixedly connected.

[0009] The beneficial effects of this utility model are: The wind-resistant pull rod of this utility model has a simple structure and can be installed on both straight and folding umbrellas. It can provide strong pulling force so that the umbrella is not easily overturned in strong winds, effectively ensuring the safety of the user. Attached Figure Description

[0011] The attached diagram lists the components represented by each number as follows: 01. Wind-resistant tie rod; 11. Fixed sleeve; 12. Movable sleeve; 13. One-way bending structure; 02. Umbrella rib; 21. Fixing component; 03. Support rod. Detailed Implementation

[0012] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0013] The umbrella has a wind-resistant pull rod 01. The umbrella includes an umbrella pole, multiple umbrella ribs 02, and a support rod 03 that connects the umbrella pole and the multiple umbrella ribs 02 respectively. The wind-resistant pull rod 01 has a fixed sleeve 11 and a movable sleeve 12 at both ends. The fixed sleeve 11 is fitted onto the support rod 03 and fixedly connected to the middle section of the support rod 03. The movable sleeve 12 is fitted onto the umbrella ribs 02. The umbrella ribs 02 have a fixing member 21 that limits the sliding distance of the movable sleeve 12. The middle section of the wind-resistant pull rod 01 has a one-way bending structure 13.

[0014] In strong winds, the wind-resistant lever 01 provides tension to the umbrella ribs 02, making them less prone to tipping over. When the umbrella is closed, the wind-resistant lever 01 bends at the one-way bending structure 13, causing the umbrella ribs 02 and the wind-resistant lever 01 to fold up. Example

[0015] like Figure 1-3 As shown, the wind-resistant pull rod 01 is an integral structure and the movable sleeve 12 can slide along the length direction of the umbrella rib 02. The fixing member 21 restricts the sliding distance of the movable sleeve 12 towards the umbrella rod.

[0016] When the umbrella is closed, the movable sleeve 12 slides away from the umbrella pole, and the one-way bending structure 13 bends, causing the umbrella ribs 02 and the wind-resistant pull rod 01 to fold up. When the umbrella is opened, the movable sleeve 12 slides towards the umbrella pole and is limited by the fixing part 21. At this time, the wind-resistant pull rod 01 is straightened and provides tension when the wind blows towards the umbrella ribs 02. The structure can be a nylon injection-molded pull strap.

[0017] In another embodiment of this invention, the wind-resistant tie rod 01 is a flat elastic sheet with a thickened structure. The thickened structure in the middle section is discontinuous to form a unidirectional bending structure 13, so that the wind-resistant tie rod 01 provides sufficient tension to prevent the wind-resistant tie rod 01 from being broken by strong winds. Example

[0018] like Figure 4-5 As shown, the wind-resistant tie rod 01 is two elastic rods connected axially. Its structure can be selected as a pin connection or a cornice nail connection. The fixing part 21 is fixedly connected to the movable sleeve 12. Optionally, the fixing part 21 and the movable sleeve 12 are an integral structure.

[0019] Both ends of the wind-resistant rod 01 are fixedly connected. When the umbrella is closed, the two ends of the wind-resistant rod 01 exert force towards the middle, and the wind-resistant rod 01 undergoes slight deformation. After the unidirectional bending structure 13 is folded up, the deformation is restored, allowing the umbrella ribs 02 and the wind-resistant rod 01 to be closed.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
