Description

Technical Field

[0001] This utility model belongs to the field of outdoor umbrella technology and relates to a windproof umbrella frame structure for outdoor umbrellas. Background Technology

[0002] Outdoor umbrellas are used outdoors, where strong winds are common. As a result, outdoor umbrellas not only need to provide shade and rain protection, but also need to improve their wind resistance. Existing outdoor umbrellas usually add more ribs to increase the structural strength of the umbrella frame, thereby improving their wind resistance.

[0003] Existing patents, such as Chinese patent application [Authorization Announcement No.: CN206453378U], disclose an outdoor umbrella frame with a detachable and telescopic structure, including an umbrella column, a pull rod assembly, and an umbrella rib assembly. The pull rod assembly includes a first pull rod and a second pull rod, and the umbrella rib assembly includes a long umbrella rib and a short umbrella rib. The umbrella column can be telescopically extended along its length. One or more of the first pull rod, the second pull rod, the long umbrella rib, and the short umbrella rib can be telescopically extended along its length. When the outdoor umbrella frame needs to be assembled, the umbrella column, the first pull rod, the second pull rod, the long umbrella rib, and the short umbrella rib are all in an extended and fixed state. When the outdoor umbrella frame needs to be disassembled and packaged, any one or more of the umbrella column, the first pull rod, the second pull rod, the long umbrella rib, and the short umbrella rib are in a retracted state. The second pull rod includes a second pull rod body and a second telescopic pull rod. One end of the second telescopic pull rod is used to hinge with the upper umbrella disc, and the other end of the second telescopic pull rod is telescopically connected to one end of the second pull rod body. The other end of the second pull rod body is used to hinge with the crank housing.

[0004] In the above structure, the upper umbrella plate is connected to the crank housing via the second pull rod, and the lower umbrella plate is hinged to the second pull rod via one of the short umbrella ribs. When the outdoor sun umbrella encounters strong winds, the upper and lower umbrella plates are connected by the rod, which will rotate circumferentially in strong winds. One end of the short umbrella rib is hinged to the lower umbrella plate, and the other end is hinged to the second pull rod. When the lower umbrella plate rotates, the connection between the short umbrella rib and the lower umbrella plate will wobble, reducing the wind resistance of the umbrella frame structure. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a windproof umbrella frame structure for outdoor umbrellas. The technical problem this utility model aims to solve is: how to address the poor wind resistance of existing umbrella frame structures.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A windproof umbrella frame structure for an outdoor umbrella includes a column, an upper umbrella plate, a lower umbrella plate, and a diagonal bar vertically slidably connected to the column. The upper end of the diagonal bar is hinged to the upper umbrella plate. One or more pull rods are hinged to the upper end of the column, and the lower end of the pull rods is hinged to the middle of the diagonal bar. A connecting rod is connected to the lower end of the upper umbrella plate. The connecting rod has a polygonal limiting tube at its end. The upper end of the lower umbrella plate protrudes to form a positioning rod that can be embedded in the limiting tube. The outer side wall of the positioning rod can fit against the inner side wall of the limiting tube. The windproof umbrella frame structure also includes two windproof rods. A mounting shell is formed by a vertical protrusion on the lower umbrella plate. The outer wall of the mounting shell has two parallel mounting walls. One end of each of the two windproof rods is hinged to the outer side wall of the diagonal bar, and the other end is hinged to the mounting wall, clamping the mounting shell.

[0008] The support post is set on the ground, with a diagonal rod slidably connected to it. The upper end of the diagonal rod is hinged to the upper umbrella tray. One or more pull rods are installed at the upper end of the support post, with the lower end of the pull rods hinged to the middle of the diagonal rods. This creates an outer triangle outside the umbrella fabric, improving the stability of the connection between the pull rods, support post, and diagonal rods. Multiple existing umbrella ribs are hinged to both the upper and lower umbrella trays. Since the lower umbrella tray needs to be pulled upwards after opening to open the umbrella ribs, a polygonal limiting tube is connected to the end of the connecting rod of the upper umbrella tray. During the upward movement of the lower umbrella tray, the upper end of the positioning rod inserts into the limiting tube. The outer wall of the positioning rod fits against the inner wall of the limiting tube, achieving circumferential positioning of the upper and lower umbrella trays. To further improve windproof performance, a mounting shell is formed on the protrusion of the lower umbrella tray, connecting the two windproof... One end of each pole is hinged to the outer wall of the diagonal bar, and the other end is hinged to the mounting wall. The other ends of the two windproof poles clamp the mounting shell. The parallel mounting walls ensure that the clamping force exerted by the windproof poles on the mounting shell is evenly distributed, improving the stability of the windproof pole installation. The mounting shell design does not affect the positioning of the positioning rod and the limiting tube, ensuring that the positioning structure of the upper and lower umbrella plates is not affected. On the other hand, while improving the structural strength of the lower umbrella plate, it also enables the installation and positioning of the windproof poles. After the upper and lower umbrella plates are positioned by the polygonal limiting tube and the positioning rod, the windproof poles will not shift from the limiting tubes after hinge. Furthermore, by clamping the positioning rods, the structural strength of the windproof pole hinge is further improved, thereby ensuring a further improvement in its wind resistance performance.

[0009] In the aforementioned windproof umbrella frame structure for outdoor umbrellas, the mounting wall is planar, the distance between the two mounting walls is greater than the width of the diagonal bar, and the upper and lower ends of the two windproof bars are inclined and set away from each other.

[0010] To ensure a better clamping effect, the diameter between the two mounting walls is set to be larger than the width of the diagonal bar, so that both windproof bars are inclined. Therefore, after installation, the mounting shell can be clamped, resulting in not only pressure but also clamping force between the windproof bars and the mounting shell, thereby improving the wind resistance at the connection between the windproof bars and the mounting shell.

[0011] In the above-mentioned windproof umbrella frame structure for outdoor umbrellas, the transverse cross-section of the mounting shell is convex, the mounting shell has a large diameter end and a small diameter end with an outer diameter smaller than the large diameter end, the small diameter end is fixedly connected to the positioning rod, and the mounting wall is located at the large diameter end.

[0012] The mounting shell adopts a convex shape, which not only ensures that the mounting shell does not affect the opening and closing of the outdoor umbrella, but also increases the distance between the two mounting walls, improving the structural strength of the lower umbrella plate. This enhances wind resistance without affecting the opening and closing of the outdoor umbrella.

[0013] In the windproof umbrella frame structure of the outdoor umbrella described above, the large-diameter end of the mounting shell protrudes radially outward.

[0014] This design allows for a shorter windproof bar, ensuring a stable visual connection and improving connection stability.

[0015] In the aforementioned windproof umbrella frame structure for outdoor umbrellas, the mounting shell and the positioning rod are integrally formed.

[0016] The one-piece molding design facilitates the assembly and disassembly of the umbrella frame and maximizes the structural strength of the lower umbrella tray, thereby improving the stability of the umbrella frame.

[0017] In the above-mentioned windproof umbrella frame structure for outdoor umbrellas, the lower umbrella plate includes an upper shell and a lower shell, both of which are disc-shaped. The middle part of the upper shell protrudes axially to form the positioning rod, and the upper shell protrudes radially to form the mounting shell. The lower end of the mounting shell presses against the lower shell.

[0018] The lower umbrella plate adopts a split design, which means that only the upper shell needs to be re-processed and molded, reducing the modification cost. Furthermore, by pressing the lower end of the mounting shell onto the lower shell, the stability of the connection between the upper and lower shells can also be improved.

[0019] In the aforementioned windproof umbrella frame structure, the upper shell has multiple mounting parts that are connected to the lower shell, distributed circumferentially along its upper edge, and the mounting shell is positioned between two adjacent mounting parts.

[0020] The lower umbrella ribs are all hinged between two adjacent mounting parts, and a mounting shell is provided between the two adjacent mounting parts. This does not affect the installation of the lower umbrella ribs, and the position of the mounting shell can also enhance the structural strength of the upper shell and improve the stability of the installation of the upper and lower shells.

[0021] In the aforementioned windproof umbrella frame structure, the windproof umbrella frame structure also includes multiple flat needle roller bearings. Flat needle roller bearings are provided between the two windproof rods and the mounting shell. The windproof rods, flat needle roller bearings, and mounting shell are connected by screws and nuts.

[0022] By using flat needle roller bearings, the two windproof rods clamp the fixed mounting shell. To avoid excessive friction between the windproof rods and the mounting shell, the flat needle roller bearings reduce friction, ensuring wind resistance while also preventing the umbrella from being affected when opening and closing.

[0023] In the aforementioned windproof umbrella frame structure, there is a gap between the hinge points of the pull rod and the inclined rod and the hinge points of the windproof rod and the inclined rod.

[0024] The spacing is designed to ensure that the hinges of the two components do not interfere with each other, making it easier to open and close the umbrella without affecting each other's swinging motion.

[0025] In the umbrella frame structure described above, the aforementioned flat needle roller bearings are provided between the two windproof rods and the diagonal rod, and the windproof rods, flat needle roller bearings, and diagonal rods are connected by screws and nuts.

[0026] By also installing a flat needle roller bearing between the windproof bar and the slant bar, the friction between the windproof bar and the slant bar is further reduced, making the opening and closing of the umbrella smoother.

[0027] Compared with the prior art, this utility model has the following advantages: By forming a mounting shell on the lower umbrella plate, one end of each of the two windproof rods is hinged to the outer wall of the diagonal rod, and the other end is hinged to the mounting wall. The other ends of the two windproof rods clamp the mounting shell. The parallel mounting walls ensure that the clamping force of the windproof rods on the mounting shell is evenly distributed, improving the stability of the windproof rod installation. The mounting shell does not affect the positioning of the positioning rod and the limiting tube, so that the positioning structure of the upper and lower umbrella plates is not affected. On the other hand, while improving the structural strength of the lower umbrella plate, it can also realize the installation and positioning of the windproof rods. After the upper and lower umbrella plates are positioned by the polygonal limiting tube and the positioning rod, the windproof rods will not be displaced from the limiting tube after hinge. Furthermore, by clamping the positioning rod, the structural strength of the windproof rod hinge is further improved, thereby ensuring further improvement in its wind resistance performance.

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figure 1 As shown, the windproof umbrella frame structure of this outdoor umbrella includes a column 1, an upper umbrella plate 2, a lower umbrella plate 3, and a diagonal rod 4 that is vertically slidably connected to the column 1. The upper end of the diagonal rod 4 is hinged to the upper umbrella plate 2. One or more pull rods 5 are hinged to the upper end of the column 1. The lower end of the pull rod 5 is hinged to the middle of the diagonal rod 4. A connecting rod 21 is connected to the lower end of the upper umbrella plate 2.

[0037] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the end of the connecting rod 21 is connected to a polygonal limiting tube 22. The upper end of the lower umbrella plate 3 protrudes to form a positioning rod 31 that can be embedded in the limiting tube 22.

[0038] The support column 1 is set on the ground, and a diagonal rod 4 is slidably connected to the support column 1. The upper end of the diagonal rod 4 is hinged to the upper umbrella tray 2. One or more pull rods 5 are set at the upper end of the support column 1, and the lower end of the pull rod 5 is hinged to the middle of the diagonal rod 4, so that the pull rod 5, the support column 1, and the diagonal rod 4 form an outer triangle outside the umbrella fabric, which improves the stability of the connection between the pull rod 5, the support column 1, and the diagonal rod 4. Multiple existing umbrella ribs are hinged to both the upper umbrella tray 2 and the lower umbrella tray 3, because after the umbrella is opened, multiple ribs are needed. Pulling the lower umbrella plate 3 upwards opens the umbrella ribs. The end of the connecting rod 21 of the upper umbrella plate 2 is connected to a polygonal limiting tube 22. During the upward movement of the lower umbrella plate 3, the upper end of the positioning rod 31 inserts into the limiting tube 22.

To further improve windproof performance, a mounting shell 32 is formed on the protrusion of the lower umbrella plate 3, connecting the two windproof... One end of each of the two windproof rods 6 is hinged to the outer wall of the diagonal rod 4, and the other end is hinged to the mounting wall 32a. The other ends of the two windproof rods 6 clamp the mounting shell 32. The parallel mounting walls 32a ensure that the clamping force of the windproof rods 6 on the mounting shell 32 is evenly distributed, improving the stability of the windproof rods 6 installation. The mounting shell 32 does not affect the positioning of the positioning rod 31 and the limiting tube 22, so that the positioning structure of the upper umbrella plate 2 and the lower umbrella plate 3 is not affected. On the other hand, while improving the structural strength of the lower umbrella plate 3, it can also realize the installation and positioning of the windproof rods 6. After the upper umbrella plate 2 and the lower umbrella plate 3 are positioned by the polygonal limiting tube 22 and the positioning rod 31, the windproof rods 6 will not be displaced from the limiting tube 22 after hinge. Furthermore, by clamping the positioning rod 31, the structural strength of the hinged windproof rods 6 is further improved, thereby ensuring further improvement of its wind resistance performance.

[0040] like Figure 5 and Figure 6As shown, the lower umbrella disc 3 includes an upper shell 33 and a lower shell 34. Both the lower shell 34 and the upper shell 33 are disc-shaped. The positioning rod 31 is formed by the protrusion in the middle of the upper shell 33. The mounting shell 32 is formed by the radial protrusion of the upper shell 33. The lower end of the mounting shell 32 presses on the lower shell 34. Multiple mounting parts 33a connected to the lower shell 34 are distributed circumferentially on the upper shell 33. The mounting shell 32 is disposed between two adjacent mounting parts 33a.

[0041] like Figure 4 and Figure 5 As shown, the windproof umbrella frame structure also includes multiple flat needle roller bearings 7. Flat needle roller bearings 7 are provided between the two windproof rods 6 and the mounting shell 32. The windproof rods 6, the flat needle roller bearings 7 and the mounting shell 32 are connected by screws 9 and nuts 8. There is a gap 10 between the hinge point of the pull rod 5 and the hinge point of the windproof rod 6 and the inclined rod 4. The aforementioned flat needle roller bearings 7 are provided between the two windproof rods 6 and the inclined rod 4.
