Description

Technical Field

[0001] This utility model relates to the technical field of umbrella rib linkage mechanism, and in particular to an umbrella rib linkage mechanism for a windproof sun umbrella. Background Technology

[0002] The windproof parasol's rib linkage mechanism primarily achieves wind resistance through multi-axis hinges and a mechanical triangular support structure. Here's a detailed analysis: The ribs are made of aerospace-grade fiberglass composite material, and each rib undergoes 2000 opening and closing fatigue tests to ensure durability. The ribs employ a cross-tension distribution system to disperse wind pressure across the entire canopy, avoiding concentrated impact on connection points. A three-axis linkage design (including main axis, branch axis, and secondary axis) forms a mechanical triangular support system. When encountering gusts, the ribs can maintain elastic deformation within 15 degrees and achieve rapid reset through a patented hinge structure. In typhoon environments with wind speeds reaching 18 m / s, the canopy maintains a stable curvature, converting wind pressure into controllable deformation through fluid dynamics optimization. Experiments show that the ribs can maintain stable support in gale-force winds (level 8), avoiding the "blooming" phenomenon common in traditional umbrellas.

[0003] In an existing windproof parasol, the rib linkage mechanism is prone to damage from strong winds during operation and use due to the small support points and force of the ribs. This affects the stability of the ribs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a linkage mechanism for the ribs of a windproof parasol.

[0005] This utility model is achieved by the following technical solution: a windproof parasol rib linkage mechanism, including a first umbrella pole, a second umbrella pole slidably connected to the top of the first umbrella pole, a third umbrella pole slidably connected to the top of the second umbrella pole, and a top support plate fixedly connected to the top of the third umbrella pole; The top support plate is internally hinged with a first connecting rod, the surface of the first connecting rod is hinged with a reinforcing rotating seat, the interior of the reinforcing rotating seat is hinged with a second connecting rod, the surface of the second connecting rod is hinged with a push sleeve, the interior of the first connecting rod is hinged with an umbrella rod, the surface of the reinforcing rotating seat is fixedly connected with an auxiliary support rod, the surface of the auxiliary support rod is fixedly connected with a reinforcing support, and the surface of the umbrella rod is inserted with an installation sleeve.

[0006] As a further improvement to the above solution, the push sleeve is slidably connected to the surface of the third umbrella pole, the push sleeve is located at the top of the second umbrella pole, and the mounting sleeve is located at the top of the first umbrella pole.

[0007] Through the above technical solution, the sliding connection of the first umbrella pole, the second umbrella pole and the third umbrella pole forms a progressively shrinking structure. When strong winds act on the umbrella surface, the wind pressure is transmitted to each level of umbrella pole through the top support plate. The friction at each connection point can consume some energy and avoid a single point bearing too large a load.

[0008] As a further improvement to the above scheme, the number of the first connecting rod and the second connecting rod is set to several, and the several first connecting rods and the second connecting rods are distributed equidistantly around the top support plate.

[0009] The above technical solution allows for the active adjustment of the umbrella's center of gravity by changing the length of the extended umbrella pole. In strong winds, the pole can be shortened to reduce the wind-affected area, while in regular use, it can be extended to expand the shading range, thus achieving a dynamic balance between functionality and safety.

[0010] As a further improvement to the above solution, the reinforced support is internally engaged with an umbrella rod, the auxiliary support rod is located at the bottom of the umbrella rod, and the first connecting rod is located at the top of the second connecting rod.

[0011] Through the above technical solution, when the wind blows the umbrella surface, the elastic deformation of the linkage system allows the umbrella ribs to tilt slightly, adjusting the angle between the umbrella surface and the wind direction, converting some of the wind energy into the rotational kinetic energy of the umbrella body, and avoiding structural overload caused by direct frontal resistance.

[0012] As a further improvement to the above solution, the number of auxiliary support rods and reinforcing supports is set to several, and the several auxiliary support rods and reinforcing supports are distributed equidistantly around the top support plate.

[0013] As a further improvement to the above solution, the top support plate is located at the top of the push sleeve, and the first connecting rod is located at the top of the push sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a hinged center between the first and second connecting rods. The reinforced rotating seat is made of high-strength alloy material, and its internal bearing design ensures smooth and wear-resistant rotation of the connecting rods. This node converts the tension from the umbrella surface into the thrust between the connecting rods, forming a stable triangular load-bearing structure. By setting auxiliary support rods extending from the reinforced rotating seat to the bottom of the umbrella pole and engaging with the reinforced support, a cross-support network is constructed between the umbrella ribs, significantly improving the torsional stiffness of the structure, especially resisting the shearing damage of lateral wind forces.

[0015] This invention features a self-locking mechanism on the inner wall of the sleeve after the umbrella pole is inserted into the mounting sleeve, preventing the pole from slipping due to vibration. Combined with a reinforcing support that engages and positions the bottom of the pole, this creates a double-fixed structure, ensuring the umbrella ribs remain stable when unfolded. The plug-in design of the umbrella pole and mounting sleeve facilitates the replacement of different rib sizes to accommodate varying umbrella canopy dimensions. Furthermore, damaged parts can be replaced individually, reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example:

[0019] Please combine Figure 1-4 The umbrella rib linkage mechanism of a windproof parasol in this embodiment includes a first umbrella pole 1, a second umbrella pole 2 slidably connected to the top of the first umbrella pole 1, a third umbrella pole 3 slidably connected to the top of the second umbrella pole 2, and a top support plate 4 fixedly connected to the top of the third umbrella pole 3. The top support plate 4 is internally hinged to a first connecting rod 5. The surface of the first connecting rod 5 is hinged to a reinforcing rotating seat 7. The interior of the reinforcing rotating seat 7 is hinged to a second connecting rod 6. The surface of the second connecting rod 6 is hinged to a push sleeve 14. The interior of the first connecting rod 5 is hinged to an umbrella pole 10. The surface of the reinforcing rotating seat 7 is fixedly connected to an auxiliary support rod 11. The surface of the auxiliary support rod 11 is fixedly connected to a reinforcing support 12. The surface of the umbrella pole 10 is inserted with an installation sleeve 13. By setting it as the hinge center between the first connecting rod 5 and the second connecting rod 6, the reinforcing rotating seat 7 is made of high-strength alloy material. Its internal bearing design makes the connecting rod rotate smoothly and is wear-resistant. This node converts the tension from the umbrella surface into the pushing force between the connecting rods, forming a stable triangular load-bearing structure. By setting the auxiliary support rod 11 to extend from the reinforcing rotating seat 7 to the bottom of the umbrella pole 10 and to be fixedly engaged with the reinforcing support 12, a cross support network is built between the umbrella ribs, which greatly improves the torsional stiffness of the structure, especially resisting the shearing damage of the lateral wind force.

[0020] The push sleeve 14 is slidably connected to the surface of the third umbrella pole 3, the push sleeve 14 is located at the top of the second umbrella pole 2, and the mounting sleeve 13 is located at the top of the first umbrella pole 1.

[0021] The sliding connection of the first umbrella pole 1, the second umbrella pole 2 and the third umbrella pole 3 forms a progressively shrinking structure. When strong winds act on the umbrella surface, the wind pressure is transmitted to each level of umbrella pole 10 through the top support plate 4. The friction at each connection point can consume some energy and avoid excessive load on a single point.

[0022] The number of first connecting rods 5 and second connecting rods 6 is set to several, and the several first connecting rods 5 and second connecting rods 6 are distributed equidistantly around the top support plate 4.

[0023] By adjusting the extension length of the umbrella pole 10, the height of the umbrella's center of gravity can be actively changed. When encountering strong winds, the umbrella pole 10 can be shortened to reduce the wind-receiving area, while during normal use, it can be extended to expand the shading range, thus achieving a dynamic balance between functionality and safety.

[0024] The reinforcing support 12 has an internal snap-fit ​​umbrella rod 10, an auxiliary support rod 11 located at the bottom of the umbrella rod 10, and a first connecting rod 5 located at the top of the second connecting rod 6. After the umbrella rod 10 is inserted into the mounting sleeve 13, it achieves self-locking through the friction texture of the inner wall of the sleeve, preventing the umbrella rod 10 from slipping due to vibration. Together with the snap-fit ​​positioning of the bottom of the umbrella rod 10 by the reinforcing support 12, a double fixation is formed from top to bottom, ensuring the stability of the umbrella ribs after they are unfolded. The plug-in design of the umbrella rod 10 and the mounting sleeve 13 makes it easy to replace umbrella ribs of different specifications to meet the needs of different sized umbrella canopies. At the same time, damaged parts can be replaced individually when damaged, reducing maintenance costs.

[0025] When the wind blows the canopy, the elastic deformation of the linkage system allows the ribs to tilt slightly, adjusting the angle between the canopy and the wind direction, converting some of the wind energy into the rotational kinetic energy of the canopy, and avoiding structural overload caused by direct frontal resistance.

[0026] The number of auxiliary support rods 11 and reinforcing supports 12 is set to several, and the several auxiliary support rods 11 and reinforcing supports 12 are distributed equidistantly around the top support plate 4.

[0027] The top support plate 4 is located on top of the push sleeve 14, and the first connecting rod 5 is located on top of the push sleeve 14.

[0028] The implementation principle of the umbrella rib linkage mechanism of a windproof parasol in this embodiment is as follows: A high-strength alloy material is used as the hinge center between the first connecting rod 5 and the second connecting rod 6. Its internal bearing design ensures smooth and wear-resistant rotation of the connecting rods. This node converts the tension from the umbrella surface into pushing force between the connecting rods, forming a stable triangular load-bearing structure. An auxiliary support rod 11 extends from the reinforced rotating seat 7 to the bottom of the umbrella rod 10 and is fixedly engaged with the reinforced support 12, thus constructing a cross-support network between the umbrella ribs. The structure's torsional stiffness is significantly improved, especially against shearing damage from lateral wind forces. By inserting the umbrella pole 10 into the mounting sleeve 13, the friction texture on the inner wall of the sleeve enables self-locking, preventing the umbrella pole 10 from slipping due to vibration. Combined with the reinforcing support 12, which engages and positions the bottom of the umbrella pole 10, a double-fixed structure is formed, ensuring the stability of the umbrella ribs after deployment. The plug-in design of the umbrella pole 10 and the mounting sleeve 13 facilitates the replacement of umbrella ribs of different specifications to meet the needs of different sized umbrella canopies. In addition, damaged parts can be replaced individually, reducing maintenance costs.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
