This utility model discloses a sun umbrella with a riveted structure that enhances wind resistance. It includes a support mechanism with an umbrella canopy. The support mechanism comprises a main pole and adjustable umbrella ribs slidably mounted on the main pole. The main pole also has evenly distributed first umbrella ribs hinged to it. The first umbrella ribs, adjustable umbrella ribs, and second umbrella ribs are connected together by riveting components. Movable rivets allow relative rotation of the components, ensuring the sun umbrella can be opened and closed normally. The C-shaped structure of the limiting frame restricts the upward movement of the second umbrella ribs, preventing the umbrella canopy from flipping upwards in strong winds. Elastic sleeves and friction-enhancing grooves increase the friction between the second umbrella ribs and the limiting frame, preventing the second umbrella ribs from flipping downwards. The magnetic attraction of the magnetic components and protrusions further enhances the stability of the second umbrella ribs within the limiting frame, forming multiple layers of protection. Without affecting the normal use of the sun umbrella, this design enhances the wind resistance of the riveted parts and the overall structure, minimizing wind damage to the sun umbrella.

Description

Technical Field

[0001] This utility model relates to the field of umbrella frame technology, specifically to a sun umbrella with a riveting structure that improves wind resistance. Background Technology

[0002] As a common outdoor sunshade and sun protection tool, the parasol is widely used in daily life. It can be seen in parks, beaches, courtyards and commercial districts. It can not only shield people from the sun and provide shade, but also protect them from light rain to a certain extent, bringing convenience to outdoor activities. However, parasols often face the test of wind during use, especially in outdoor environments where the wind force is unpredictable. Strong winds can easily damage parasols, affecting their service life and safety.

[0003] The structural stability of a parasol largely depends on the connection method between its various components. Riveting is a common method for connecting parasol components, using rivets to fix the ribs, shaft, and other parts together, ensuring that the parasol can be opened and closed normally. However, in actual use, the existing riveting structure of parasols has certain deficiencies in wind resistance. When encountering strong winds, the wind force acts on the parasol surface, and then transmits the force to the ribs and riveted parts. Due to the unreasonable design of the existing riveting structure, the frame structure of the parasol is damaged, the parasol surface collapses, and it can no longer be used. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing riveting structures for improving wind resistance of sun umbrellas, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A sun umbrella with a riveted structure to improve wind resistance includes a support mechanism, on which an umbrella canopy is provided. The support mechanism includes a main pole and adjustable umbrella ribs slidably mounted on the main pole. The main pole is also hinged with evenly distributed first umbrella ribs, and a riveting member is provided between the first umbrella ribs and the adjustable umbrella ribs. A second umbrella rib is provided inside the riveting member. The riveting component includes an insert block sleeved on the end of the adjusting umbrella rib.

The first umbrella rib is inserted into the slot. The insert block also has a limit frame on its outer wall. The second umbrella rib is inserted into the limit frame and slidably installed. An elastic sleeve is provided inside the limit frame. The inner wall of the elastic sleeve has evenly distributed friction-enhancing textures. The limit frame, the elastic sleeve, and the friction-enhancing textures together restrict the flipping of the second umbrella rib.

[0007] As a preferred embodiment of the sun umbrella with a riveted structure that improves wind resistance according to this utility model, the limiting frame is configured as a C-shaped structure.

[0008] As a preferred embodiment of the sun umbrella with a riveted structure that improves wind resistance according to this utility model, the limiting frame is provided with a number of magnetic components, and the magnetic components are magnetically engaged with the second umbrella rib.

[0009] As a preferred embodiment of the sun umbrella with a riveted structure that improves wind resistance according to the present invention, a plurality of protrusions are provided on the outer wall of the second umbrella rib, and the protrusions correspond one-to-one with the magnetic components.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In this design, the first umbrella rib, adjusting umbrella rib, and second umbrella rib are connected together by riveting components. Movable rivets enable relative rotation of each component, ensuring the parasol can be opened and closed normally. The C-shaped structure of the limiting frame restricts the upward flipping of the second umbrella rib, preventing the canopy from flipping upward in strong winds. The elastic sleeve and friction-enhancing texture increase the friction between the second umbrella rib and the limiting frame, preventing the second umbrella rib from flipping downward. The magnetic attraction of the magnetic component and the protrusion further enhances the stability of the second umbrella rib within the limiting frame, forming multiple layers of protection. Without affecting the normal use of the parasol, the wind resistance of the riveted parts and the overall structure is enhanced, minimizing the damage of wind to the parasol.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example 1

[0016] Please see Figures 1-5 This utility model provides a technical solution: A sun umbrella with a riveted structure to improve wind resistance can enhance the structural stability of the sun umbrella in strong wind environments, prevent the riveted parts from loosening, deforming or breaking, prevent the umbrella canopy from collapsing, extend the service life of the sun umbrella, and ensure safety during use.

[0017] This sun umbrella with a riveted structure to improve wind resistance includes a support mechanism 1, which is the frame of the sun umbrella and supports the canopy 3. The canopy 3 is mounted on the support mechanism 1 and is used for sun protection and light rain protection. The support mechanism 1 includes a main pole 2 and adjustable umbrella ribs 5 slidably mounted on the main pole 2. The main pole 2 is the central support rod of the sun umbrella, and the adjustable umbrella ribs 5 can slide along the main pole 2 to adjust the unfolded and retracted state of the sun umbrella. The main pole 2 is also hinged with evenly distributed first umbrella ribs 4, which support the top part of the canopy 3. A riveting piece 7 is provided between the first umbrella ribs 4 and the adjustable umbrella ribs 5 for connecting... The first umbrella rib 4, the adjusting umbrella rib 5, and the second umbrella rib 6 are connected. The second umbrella rib 6 is provided inside the riveting component 7. The second umbrella rib 6 assists in supporting the umbrella surface 3 and enhances the overall structural stability. The riveting component 7 includes an insert block 8 sleeved on the end of the adjusting umbrella rib 5. The insert block 8 is fixedly connected to the adjusting umbrella rib 5. A slot 10 is provided on the outer wall of the insert block 8. The slot 10 is used to accommodate the end of the first umbrella rib 4. The insert block 8 is rotatably installed with the second umbrella rib 6 and the first umbrella rib 4 through a movable rivet 11. The movable rivet 11 allows the second umbrella rib 6 and the first umbrella rib 4 to rotate relative to the insert block 8. The first umbrella rib 4 is inserted into the slot 10 to ensure the stability of the connection between the first umbrella rib 4 and the insert block 8.

[0018] A limiting frame 9 is also provided on the outer wall of the insert block 8. The limiting frame 9 is used to limit the flipping range of the second umbrella rib 6. The second umbrella rib 6 is inserted into the limiting frame 9 and slidably installed. The limiting frame 9 is designed with a C-shaped structure, so that while storing the second umbrella rib 6, the closed structure formed by itself can limit the second umbrella rib 6 from flipping upward. An elastic sleeve 12 is provided inside the limiting frame 9. The elastic sleeve 12 is made of rubber, which can increase the friction when the second umbrella rib 6 is engaged in the limiting frame 9, and prevent the second umbrella rib 6 from flipping downward. The inner wall of the elastic sleeve 12 is provided with evenly distributed friction-enhancing textures 14, which further enhance the friction. The limiting frame 9 is provided with several magnetic attracting elements 13, which are magnets and magnetically cooperate with the second umbrella rib 6. The second umbrella rib 6 is made of magnetic materials containing iron or other magnetic materials. The outer wall of the second umbrella rib 6 is provided with several protrusions 15, which are magnetic materials and correspond one-to-one with the magnetic attracting elements 13. The magnetic attraction of the magnetic attracting elements 13 and the protrusions 15 provides magnetic locking.

[0019] This sun umbrella, featuring a riveted structure to enhance wind resistance, connects the first umbrella rib 4, the adjusting umbrella rib 5, and the second umbrella rib 6 together via riveting 7. Movable rivets 11 enable relative rotation of the components, ensuring the sun umbrella can be opened and closed normally. The C-shaped structure of the limiting frame 9 restricts the upward movement of the second umbrella rib 6, preventing the canopy 3 from being lifted upwards in strong winds. The elastic sleeve 12 and the friction-enhancing texture 14 increase the friction between the second umbrella rib 6 and the limiting frame 9, preventing the second umbrella rib 6 from turning downwards. The magnetic attraction of the magnetic component 13 and the protrusion 15 further enhances the stability of the second umbrella rib 6 within the limiting frame 9, forming multiple layers of protection. These structures work together to enhance the wind resistance of the riveted parts and the overall structure without affecting the normal use of the sun umbrella, minimizing the damage caused by wind.

[0020] In use, the main pole 2 of the parasol is fixed to the ground or other support. The adjusting rib 5 is pushed to slide upwards along the main pole 2. The adjusting rib 5 causes the riveting piece 7 to move upwards, thereby unfolding the first rib 4 and the second rib 6. During the unfolding process, the end of the first rib 4 slides within the slot 10 and rotates around the movable rivet 11. The second rib 6 rotates around the movable rivet 11 and engages within the limiting frame 9, contacting the elastic sleeve 12 within the limiting frame 9. The elastic sleeve 12 is compressed, generating friction. The friction-enhancing texture 14 further increases the friction. When the second rib 6 is fully unfolded, the magnetic attractor 13 within the limiting frame 9 attracts the protrusion 15 on the second rib 6, forming a magnetic lock. Combined with the friction provided by the elastic sleeve 12, the second rib 6 is stabilized within the limiting frame 9. The umbrella canopy 3 is supported and unfolded by the first umbrella rib 4 and the second umbrella rib 6, and can be used normally. When encountering strong winds, the wind force acts on the umbrella canopy 3, and the force is transmitted to the second umbrella rib 6. Since the limiting frame 9 has a C-shaped structure, it restricts the second umbrella rib 6 from tilting upwards. At the same time, the friction provided by the elastic sleeve 12 and the friction-enhancing texture 14, as well as the magnetic force between the magnetic suction part 13 and the protrusion 15, prevent the second umbrella rib 6 from flipping downwards, thereby maintaining the stability of the umbrella canopy 3 and preventing the second umbrella rib 6 from causing the umbrella canopy 3 to flip. When it is necessary to close the sun umbrella, push the adjusting umbrella rib 5 to slide downwards along the main pole 2. The adjusting umbrella rib 5 drives the riveting part 7 to move downwards. The second umbrella rib 6 overcomes the magnetic force of the magnetic suction part 13 and the friction force of the elastic sleeve 12, slides out from the limiting frame 9, and rotates around the movable rivet 11. The first umbrella rib 4 also rotates around the movable rivet 11, and finally the sun umbrella is closed.

[0021] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
