Description

Technical Field

[0001] This utility model relates to the field of umbrella manufacturing technology, and in particular to a novel umbrella rib structure. Background Technology

[0002] Umbrellas are widely used tools for rain protection or sun protection in people's daily lives. One of their core components is the umbrella rib structure, which is responsible for the opening, closing, and support of the umbrella fabric.

[0003] In existing technologies, the design of an umbrella's rib structure directly affects its ease of use and durability. Many traditional umbrella rib structures, in pursuit of low manufacturing costs and structural simplicity, typically employ a basic link design.

[0004] However, this simple linkage structure often requires users to apply significant pushing or pulling force during actual opening and closing, resulting in less smooth operation and a poor user experience. Furthermore, this structure often lacks effective auxiliary mechanisms to help the umbrella ribs maintain stable locking when fully open or fully closed, making it prone to springback or loosening.

[0005] More importantly, in order to simplify the design, traditional umbrella ribs often have insufficient structural strength. These ribs usually have simple cross-sectional shapes and lack targeted structural optimization, which makes the umbrella ribs very prone to bending, deformation or even breakage when encountering external forces such as strong winds, greatly shortening the lifespan of the umbrella.

[0006] Therefore, existing umbrella rib structures generally suffer from problems such as unsmooth opening and closing, lack of auxiliary locking mechanisms, insufficient structural strength of the ribs themselves, and susceptibility to damage, making it difficult to simultaneously meet users' dual needs for ease of operation and structural durability.

[0007] Therefore, this utility model proposes a novel umbrella rib structure to address the shortcomings of existing technologies. Utility Model Content

[0010] The first connecting rod has a first groove inside, with the opening of the first groove facing upwards towards the umbrella fabric; the second connecting rod has a second groove inside, with the opening of the second groove facing upwards towards the umbrella fabric.

[0011] The connecting mechanism includes a spring, a fixed shaft, a hook, and a fixing block. The upper end of the spring is arranged around the outer wall of the fixed shaft, which is the rotatable connection point between the control rod and the second transmission rod.

Detailed Implementation

[0028] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to Figures 1 to 4 This utility model provides a novel umbrella rib structure, which aims to solve the problems of poor linkage and insufficient strength of existing umbrella rib structures.

[0030] like Figure 1 and Figure 2 As shown, the novel umbrella rib structure includes a control lever 1 and an umbrella rib mechanism 2 that is linked and cooperates with the control lever 1. The control lever 1 is used by the user to directly operate and control the opening and closing of the umbrella, while the umbrella rib mechanism 2 serves as the linkage support and transmission body for the entire umbrella rib.

[0031] The specific structural design of the umbrella rib mechanism 2 is as follows: The umbrella rib mechanism 2 includes a second connecting rod 203, a first connecting rod 201, a first transmission rod 205, a rotating block 5, and a third connecting rod 4. The upper end of the control rod 1 is rotatably connected to the second connecting rod 203 near the center of the umbrella rib mechanism 2. The inside of the control rod 1 is rotatably connected to the upper end of the second transmission rod 301. The lower end of the second transmission rod 301 is rotatably engaged with the upper end of the second connecting rod 203 to realize the transmission of force. The outer surface of the second connecting rod 203 is rotatably connected to the upper end of the first connecting rod 201 to ensure synchronous movement between the two rods. The inner surface of the first connecting rod 201 is rotatably connected to the upper end of the first transmission rod 205 to transmit the rotation of the first connecting rod 201 to the first transmission rod 205. The lower end of the first transmission rod 205 is rotatably engaged with the outer surface of the rotating block 5 to drive the rotating block 5 to rotate around the lower end of the second connecting rod 203, thereby driving the entire umbrella rib mechanism 2 to open or close. A third connecting rod 4 is provided on the outer surface of the rotating block 5. The third connecting rod 4 serves as the end support rod of the umbrella rib mechanism 2, and its movement directly affects the degree of opening of the umbrella fabric.

[0032] The first connecting rod 201 has a first groove 202 inside, with the opening of the first groove 202 facing the upper direction of the umbrella fabric, which effectively enhances the structural strength of the first connecting rod 201. Similarly, the second connecting rod 203 also has a second groove 204 inside, with the opening of the second groove 204 also facing the upper direction of the umbrella fabric, which further enhances the strength of the second connecting rod 203, thereby improving the overall wind resistance and deformation resistance of the umbrella rib structure.

[0033] The new umbrella rib structure also includes a connecting mechanism 3, which comprises a spring 303, a fixed shaft 304, a hook 306, and a fixing block 302. The upper end of the spring 303 is arranged around the outer wall of the fixed shaft 304, which is the rotatable connection point between the control rod 1 and the second transmission rod 301. The hook 306, connected to the lower end of the spring 303, is inserted into a through hole 305 inside the fixing block 302, which is fixed to the lower surface of the first connecting rod 201. The spring 303 is designed to provide auxiliary elasticity, which can assist the umbrella ribs in opening quickly when the umbrella is open, or provide tightening force when the umbrella is closed, and may provide locking support when the umbrella is fully open or closed, improving user experience and umbrella rib stability.

[0034] The connecting mechanism 3 includes a spring 303, a fixed shaft 304, a hook 306, and a fixing block 302. The upper end of the spring 303 is arranged around the outer wall of the fixed shaft 304, which is the rotatable connection point between the control rod 1 and the second transmission rod 301. The outer wall of the fixed shaft 304 is provided with an annular groove, and the upper end of the spring 303 is arranged around the inside of the annular groove to ensure that the spring 303 can be stably positioned on the fixed shaft 304 without axial sliding.

[0035] Meanwhile, the other end of the spring 303 is connected to a hook 306. The hook 306 has a C-shaped structure and is designed to be easily inserted and removed, enabling quick installation and removal of the spring 303. The hook 306 is inserted into the through hole 305 inside the fixing block 302. The through hole 305 is a circular hole, and a detachable insertion fit is formed between the hook 306 and the through hole 305. After the hook 306 is inserted into the through hole 305, a limiting fit is formed between the hook 306 and the through hole 305, effectively preventing the hook 306 from accidentally falling off. The fixing block 302 is fixed to the lower surface of the first connecting rod 201 by bolt connection. The fixing block 302 is provided with at least two bolt holes to ensure that the connection between the fixing block 302 and the first connecting rod 201 is firm and reliable and will not loosen due to frequent opening and closing of the umbrella ribs.

[0036] This connecting mechanism 3 provides auxiliary force for the opening and closing process of the umbrella rib mechanism 2 through the elastic action of the spring 303. When opening the umbrella, the spring 303 may provide an initial spring force, making it easier to unfold the umbrella ribs. When closing the umbrella, the spring 303 can assist in tightening the umbrella ribs, or when the umbrella is fully open or closed, its elasticity can maintain the locked state of the umbrella ribs, improving the stability of the umbrella ribs and the convenience of operation.

[0037] As a preferred embodiment, in order to further enhance the structural strength of the first connecting rod 201 and reduce its weight, the first groove 202 extends along the length of the first connecting rod 201, and the cross-sectional shape of the first groove 202 is U-shaped. This U-shaped cross-section design optimizes the material distribution while ensuring sufficient strength, and further improves the bending and torsional resistance of the rod.

[0038] As another preferred embodiment, in order to further enhance the structural strength of the second connecting rod 203 and meet specific force transmission requirements, the second groove 204 extends along the length direction of the second connecting rod 203. The cross-sectional shape of the second groove 204 is V-shaped. The V-shaped cross-section provides stronger compressive and shear resistance, and is especially suitable for areas subjected to concentrated loads.

[0039] In another preferred embodiment, to ensure the reliability of the connection between the fixing block 302 and the first connecting rod 201, the fixing block 302 is fixed to the lower surface of the first connecting rod 201 by bolt connection. The fixing block 302 is provided with at least two bolt holes, and multiple bolts are used for fastening, which effectively disperses the connection stress and avoids loosening or damage caused by excessive force on a single bolt.

[0040] In another preferred embodiment, to ensure the stability and reliability of the fit between the hook 306 and the through hole 305, the hook 306 has a C-shaped structure, and the through hole 305 is a circular hole. A detachable insertion fit is formed between the hook 306 and the through hole 305. After insertion into the through hole 305, a limiting fit is formed between the hook 306 and the through hole 305, effectively preventing the hook 306 from accidentally dislodging under the action of the spring 303 or during umbrella rib movement, thus ensuring the continuous and effective function of the spring 303 mechanism.

[0041] As a further preferred embodiment, in order to simplify the manufacturing process and improve the overall integrity of the components, the rotating block 5 and the third connecting rod 4 are integrally formed and fixedly connected. The integral forming eliminates additional connecting parts and assembly steps, reduces potential failure points, and improves the structural rigidity of the components.

[0042] In another preferred embodiment, to improve the wear resistance and extend the service life of each rotating connection point of the umbrella rib mechanism 2, wear-resistant shims are provided at the rotating connection points between the second connecting rod 203 and the first connecting rod 201, and at the rotating connection points between the first connecting rod 201 and the first transmission rod 205. The wear-resistant shims can reduce direct friction between metal parts, reduce wear, and ensure smooth rotation.

[0043] As another preferred embodiment, in order to improve the positioning stability of the spring 303 on the fixed shaft 304, an annular groove is provided on the outer wall of the fixed shaft 304, and the upper end of the spring 303 is arranged around the inside of the annular groove, which effectively prevents the spring 303 from shifting axially during frequent opening and closing movements and ensures that it is always in the correct working position.

[0044] Working Principle: When the user needs to open the umbrella, by operating the control lever 1, the movement of the control lever 1 drives the second transmission rod 301 to move in a specific direction. The movement of the second transmission rod 301 is linked with the second connecting rod 203, which is rotatably connected to it, pushing or pulling the second connecting rod 203. The movement of the second connecting rod 203 is transmitted through the first connecting rod 201, which is rotatably connected to its outer surface. The first transmission rod 205, which is rotatably connected to the inner surface of the first connecting rod 201, transmits the movement to the first transmission rod 205. The movement of the first transmission rod 205 is further linked with the rotating block 5, which is rotatably engaged with its outer surface, driving the rotating block 5 to rotate around the lower end of the second connecting rod 203. The third connecting rod 4, which is set on the outer surface of the rotating block 5, then unfolds outward, thereby opening the umbrella ribs. When the user needs to close the umbrella, the control lever 1 moves in the opposite direction. Through the same linkage mechanism, all connecting rods and rotating block 5 will move in the opposite direction, causing the third connecting rod 4 to close inward, completing the folding of the umbrella ribs.

[0045] During this process, the spring 303 plays an auxiliary role through its connecting mechanism 3. When the umbrella ribs open, the energy stored in the spring 303 or the elastic force released can assist the rapid pop-out of the umbrella ribs, reducing the resistance during user operation. When the umbrella ribs are fully open or closed, the elasticity of the spring 303 acts between the fixing block 302 and the first connecting rod 201, providing a locking or holding force to maintain the stability of the umbrella ribs in a specific position and prevent accidental opening and closing. The first groove 202 inside the first connecting rod 201 and the second groove 204 inside the second connecting rod 203 effectively increase the structural rigidity and deformation resistance of the rods during the opening and closing and stress process of the umbrella ribs, ensuring the overall stability and reliability of the umbrella ribs.
