Description

Technical Field

[0001] This utility model belongs to the field of outdoor umbrella technology and relates to an 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 sunshade that can be adjusted at all angles, including an umbrella column and an umbrella body. The umbrella body is hinged to the upper end of the umbrella column via a first connecting rod. The umbrella column is also provided with a sliding member that is hinged to the umbrella body. The sliding member is sleeved on the umbrella column and slides up and down on the umbrella column. The umbrella column is provided with a first handle for opening and closing the umbrella body. The first handle is connected to the umbrella body via a pull rope. The first handle realizes the unfolding and folding of the umbrella body by winding and releasing the pull rope. It also includes a support, and the umbrella column is connected to the support. The umbrella column is provided with a second handle for horizontally rotating the umbrella column. The umbrella column makes a horizontal rotation movement about the support through the second handle. The umbrella body includes umbrella ribs. One of the umbrella ribs of the umbrella body serves as a second connecting rod. One end of the second connecting rod is hinged to the upper umbrella plate on the umbrella body, and the other end is hinged to the sliding member. The first connecting rod is connected to the umbrella body by being hinged to the middle of the second connecting rod.

[0004] In the above structure, the upper umbrella plate is connected to the sliding component and the upper umbrella plate by one of the umbrella ribs as the second connecting rod. The lower umbrella plate is connected to the second connecting rod by one of the umbrella ribs on the lower umbrella plate. Since the connection between the lower umbrella plate and the second connecting rod is made by one of the umbrella ribs, with one end of the umbrella rib hinged to the lower umbrella plate and the other end hinged to the second connecting rod, there is no circumferential positioning between the upper and lower umbrella plates when the outdoor sun umbrella encounters strong winds. This makes the lower and upper umbrella plates prone to circumferential swaying, which in turn causes the umbrella ribs to wobble at the connection with the lower umbrella plate, affecting the wind resistance performance 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 frame structure for outdoor umbrellas. The technical problem to be solved by this utility model is: how to solve the problem of poor wind resistance in existing umbrella frame structures.

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

[0007] An outdoor umbrella frame structure 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 ends of the pull rods are all 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 frame structure also includes two windproof rods. One end of each windproof rod is hinged to the outer side wall of the diagonal bar, and the other end of each windproof rod is hinged to the outer side wall of the positioning rod, clamping the positioning rod.

[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 wind resistance, two windproof... The windproof rod has one end hinged to the outer wall of the diagonal rod and the other end hinged to the outer wall of the positioning rod. The other ends of the two windproof rods clamp the positioning rod. By using two windproof rods, the overall structural strength of the umbrella frame is improved. The hinge between the windproof rod and the diagonal rod does not affect the hinge between the pull rod and the diagonal rod. The windproof rod, diagonal rod, and connecting rod form an inner triangle located within the umbrella fabric, improving the structural strength of the entire umbrella frame. To further enhance the wind resistance of the umbrella frame, the windproof rod is directly hinged to the outer wall of the positioning rod. The positioning rod and the limiting tube ensure that the windproof rod will not shift after hinged. Furthermore, by clamping the positioning rod, the structural strength of the windproof rod hinge is further improved, thus ensuring further improvement in its wind resistance.

[0009] In the above-mentioned outdoor umbrella frame structure, the outer wall of the positioning rod is hexagonal, the diameter of the positioning rod is greater than the width of the diagonal rod, and the upper and lower ends of the two windproof rods are inclined and set away from each other.

[0010] To ensure a better clamping effect, the diameter of the positioning rod is set to be larger than the width of the diagonal rod, so that both windproof rods are set at an angle. Therefore, after installation, the positioning rod can be clamped, so that there is not only pressure but also clamping force between the windproof rod and the positioning rod, thereby improving the wind resistance at the connection between the windproof rod and the positioning rod.

[0011] In the above-mentioned umbrella frame structure, the umbrella frame structure includes multiple flat needle roller bearings, and flat needle roller bearings are provided between the two windproof rods and the positioning rod. The windproof rods, flat needle roller bearings and positioning rods are connected by screws and nuts.

[0012] By using a flat needle roller bearing, the positioning rod is clamped between the two windproof rods. To avoid excessive friction between the windproof rod and the positioning rod, the flat needle roller bearing reduces friction, ensuring wind resistance while also preventing the umbrella from being affected when opening and closing.

[0013] In the umbrella frame structure described above, the positioning rod has two parallel connecting walls, and two windproof rods are located on the outer walls of the two connecting walls and connected to the positioning rod by screws and nuts.

[0014] By connecting the windproof rods to two parallel connecting walls, the two windproof rods connected by screws and nuts are subjected to the same force and are set up symmetrically, so they can be more balanced when swinging, making it easier to open and close the umbrella and improving wind resistance.

[0015] In the above-mentioned outdoor umbrella frame structure, there is a gap between the hinge points of the pull rod and the diagonal rod and the hinge points of the windproof rod and the diagonal rod.

[0016] 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.

[0017] In the umbrella frame structure described above, the two windproof poles and the diagonal pole are each provided with the aforementioned flat needle roller bearings, and the windproof poles, flat needle roller bearings and diagonal poles are connected by screws and nuts.

[0018] 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.

[0019] Compared with the prior art, this utility model has the following advantages: By using two windproof rods, the overall structural strength of the umbrella frame is improved, and the hinge of the windproof rod and the diagonal rod does not affect the hinge of the pull rod and the diagonal rod. The windproof rod, the diagonal rod, and the connecting rod form an inner triangle located within the umbrella fabric, which improves the structural strength of the entire umbrella frame. In order to further enhance the wind resistance of the umbrella frame, the windproof rod is directly hinged to the outer wall of the positioning rod. Through the positioning rod and the limiting tube, the windproof rod will not be displaced after hinge. Furthermore, by clamping the positioning rod, the structural strength of the hinge of the windproof rod is further improved, thereby ensuring a further improvement in its wind resistance.

[0025] 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.

[0026] like Figure 1 As shown, the 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 lower ends of the pull rods 5 are all 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.

[0027] Specifically, such as Figure 1 and Figure 2 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. The outer side wall of the positioning rod 31 can fit against the inner side wall of the limiting tube 22. The umbrella frame structure also includes two windproof rods 6. One end of the two windproof rods 6 is respectively hinged to the outer side wall of the inclined rod 4, and the other end of the two windproof rods 6 is respectively hinged to the outer side wall of the positioning rod 31 and clamps the positioning rod 31. The outer side wall of the positioning rod 31 is hexagonal, and the diameter of the positioning rod 31 is greater than the width of the inclined rod 4. The upper and lower ends of the two windproof rods 6 are inclined and set away from each other.

[0028] 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 disc 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 disc 2 and the lower umbrella disc 3. Since the lower umbrella disc 3 needs to be pulled upward after opening the umbrella to open the umbrella ribs, the end of the connecting rod 21 of the upper umbrella disc 2 is connected to a polygonal limiting tube 22. During the upward movement of the lower umbrella disc 3, the upper end of the positioning rod 31 is inserted into the limiting tube 22. The outer side wall of the positioning rod 31 fits against the inner side wall of the limiting tube 22 to achieve circumferential positioning of the upper umbrella disc 2 and the lower umbrella disc 3. In order to further improve the windproof performance, a series of additional features are provided. Two windproof rods 6 are used. One end of the windproof rod 6 is hinged to the outer wall of the diagonal rod 4, and the other end is hinged to the outer wall of the positioning rod 31. The other ends of the two windproof rods 6 clamp the positioning rod 31. By using two windproof rods 6, the overall structural strength of the umbrella frame is improved. The hinge of the windproof rod 6 and the diagonal rod 4 does not affect the hinge of the pull rod 5 and the diagonal rod 4. The windproof rod 6, the diagonal rod 4, and the connecting rod 5 form an inner triangle located within the umbrella fabric, which improves the structural strength of the entire umbrella frame. In order to further enhance the wind resistance of the umbrella frame, the windproof rod 6 is directly hinged to the outer wall of the positioning rod 31. Through the positioning of the positioning rod 31 and the limiting tube 22, the windproof rod 6 will not be displaced after hinge. Furthermore, by clamping the positioning rod 31, the structural strength of the hinge of the windproof rod 6 is further improved, thereby ensuring its wind resistance is further improved.
