Description

Technical Field

[0001] This utility model belongs to the field of umbrella technology, and more specifically, relates to a highly stable umbrella frame. Background Technology

[0002] As everyday tools for sheltering from rain and sun, umbrellas are increasingly used in a wider range of fields as people's lives become richer. Their application frequency is constantly increasing in various marketing activities, disaster relief, and other fields. The structure of the umbrella frame, an important component of the umbrella, enables the rapid opening and closing of the umbrella, bringing many conveniences to people's lives.

[0003] Existing umbrella frames typically consist of a main umbrella pole, a base, and umbrella ribs. While they allow for quick folding and unfolding, they suffer from insufficient structural stability during use after unfolding. The support points between the ribs rely solely on friction at the hinges, making them prone to swaying in strong winds, potentially leading to deformation at the hinges, especially in high winds, which can cause structural loosening or even tipping over. The stability of the frame structure directly impacts user experience and lifespan. For example, a folding umbrella frame disclosed in Chinese invention patent literature (CN201720458346.5) improves overall structural stability by using adhesive to fix the support rod with several mounting sleeves on the first and second connecting parts. However, after long-term use, the adhesive tends to age and detach, causing loosening between the support rod and the connecting parts, affecting the stability and lifespan of the umbrella frame.

[0004] Therefore, we need to design an umbrella support structure that is simple in structure, has high stability when the umbrella canopy is deployed, and has a long service life. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a highly stable umbrella support with a simple structure. By setting a double limiting and fixing structure of slot and platform, the shaking of the umbrella support after being subjected to external force after being unfolded is effectively limited, thereby enhancing the stability of the umbrella support in the unfolded state.

[0006] This utility model discloses a highly stable umbrella support, comprising an umbrella main pole, a fixed base, a movable base, and several umbrella rib assemblies. The fixed base is detachably installed on the top of the umbrella main pole, and the movable base is slidably connected to the umbrella main pole.

[0007] The umbrella rib assembly includes a main rib, a connecting part, and a secondary rib. One end of the main rib is hinged to a fixed base, and the other end of the main rib is hinged to one end of the connecting part. The other end of the connecting part is hinged to one end of the secondary rib, and the other end of the secondary rib is hinged to a movable base.

[0008] The connecting part has a slot on the side near the main umbrella rib, which engages with the main umbrella rib when the umbrella rib assembly is in the unfolded state; the secondary umbrella rib has a locking platform structure on the side near the connecting part, which abuts against the lower part of the connecting part when the umbrella rib assembly is in the unfolded state, thereby enhancing the structural stability of the umbrella rib assembly in the unfolded state.

[0009] As a further improvement of this utility model, the fixed base has the same number of side planes as the umbrella rib assembly, and a first hinge groove is opened at one end of the side of the fixed base, and the main umbrella rib is hinged to the first hinge groove; the movable base has the same number of side planes as the umbrella rib assembly, and a second hinge groove is opened at the end of the side of the movable base away from the first hinge groove, and the secondary umbrella rib is hinged to the second hinge groove; the movable base pulls the secondary umbrella rib and controls the opening and closing of the main umbrella rib through the connecting part.

[0010] As a further improvement of this utility model, the horizontal distance between the first hinge groove and the second hinge groove is consistent with the width of the connecting part, so as to prevent the umbrella rib main rod, the connecting part and the umbrella rib secondary rod from shifting when the umbrella rib assembly is unfolded, thereby further improving the structural stability.

[0011] As a further improvement of this utility model, the connecting part is an "L" shaped structure, with a first hinge part at one end of the longer side, which is hinged to the end of the umbrella rib main rod away from the first hinge groove; and a second hinge part at one end of the shorter side, which is hinged to the end of the umbrella rib auxiliary rod away from the second hinge groove.

[0012] As a further improvement of this utility model, a sleeve is provided on the inner side of the movable base, and the inner wall of the sleeve is slidably connected to the outer wall of the umbrella main pole, so that the umbrella rib assembly runs smoothly during the unfolding and closing process, reducing operating resistance.

[0013] As a further improvement of this utility model, the slot is set at the lower part of the connecting part, and the arc-shaped contour of the slot surface fits the umbrella rib main pole, which enhances the fit between the connecting part and the umbrella rib main pole, thereby improving the load-bearing capacity and stability of the connection.

[0014] As a further improvement of this utility model, the side of the card holder structure near the connecting part extends towards the connecting part with a sloping platform, which is used to form a sloping contact with the lower part of the connecting part when the umbrella rib assembly is unfolded. This platform plays a limiting role in the connection between the connecting part and the umbrella rib sub-rod, thereby preventing the umbrella rib sub-rod from overturning under external force and further improving the overall stability and deformation resistance of the umbrella frame.

[0015] As a further improvement of this utility model, a support rod is provided at the end of the connecting part away from the umbrella main pole. The support rod extends outward along the length of the longer side of the connecting part to support the umbrella surface, so that the umbrella surface is flatter when it is unfolded.

[0016] Compared to existing technologies, the advantages of this utility model are as follows: This utility model provides a highly stable umbrella support. The connection between the connecting part and the main umbrella rib, along with the locking structure of the secondary umbrella rib abutting against the connecting part, forms a double-limiting fixation, effectively limiting the shaking of the umbrella rib assembly after deployment. This improves the stability of the umbrella rib assembly in the deployed state, thereby enhancing the structural strength and service life of the entire umbrella support. By maintaining the horizontal distance between the first and second hinge slots consistent with the width of the connecting part, the structure is rationally designed while ensuring precise positioning of each component when the umbrella rib assembly is deployed, further improving the structural integrity. Stability; the design of sliding connection between the sleeve inside the movable base and the main umbrella rib ensures smooth operation of the umbrella rib assembly during unfolding and closing, reducing operating resistance and improving ease of use; the addition of a groove that matches the cross-sectional contour of the main umbrella rib enhances the fit between the connection and the main umbrella rib, thereby improving the load-bearing capacity and stability of the connection; the addition of an inclined platform extending from the mounting plate structure to the connection, forming an inclined surface that abuts against the lower part of the connection when the umbrella rib assembly unfolds, prevents the secondary umbrella rib from overturning under external forces, further improving the overall stability and deformation resistance of the umbrella frame.

Detailed Implementation

[0024] Specific Implementation Example 1: Please refer to... Figures 1-5 A highly stable umbrella support includes an umbrella main pole 1, a fixed base 2, a movable base 3, and several umbrella rib assemblies 4. The fixed base 2 is detachably installed on the top of the umbrella main pole 1, and the movable base 3 is slidably connected to the umbrella main pole 1.

[0025] The umbrella rib assembly 4 includes a main umbrella rib 41, a connecting part 42, and a secondary umbrella rib 43. One end of the main umbrella rib 41 is hinged to the fixed base 2, and the other end of the main umbrella rib 41 is hinged to one end of the connecting part 42. The other end of the connecting part 42 is hinged to one end of the secondary umbrella rib 43, and the other end of the secondary umbrella rib 43 is hinged to the movable base 3.

[0026] like Figure 2 The connecting part 42 shown is provided with a slot 421 on the side near the main umbrella rib 41. The slot 421 engages with the main umbrella rib 41 when the umbrella rib assembly 4 is in the unfolded state. The secondary umbrella rib 43 is provided with a locking structure 431 on the side near the connecting part 42. The locking structure 431 abuts against the lower part of the connecting part 42 when the umbrella rib assembly 4 is in the unfolded state, which is used to enhance the structural stability of the umbrella rib assembly 4 in the unfolded state. Through the double limiting and fixing of the slot 421 and the locking structure 431, the shaking of the umbrella rib assembly 4 after unfolding is effectively limited, and the stability of the umbrella rib assembly 4 in the unfolded state is improved, thereby enhancing the structural strength and service life of the entire umbrella frame.

[0027] Specifically, such as Figure 3 The fixed base 2 shown has the same number of side planes as the umbrella rib assembly 4. One end of the side of the fixed base 2 has a first hinge groove 21, and the main umbrella rib 41 is hinged to the first hinge groove 21. The movable base 3 has the same number of side planes as the umbrella rib assembly 4. One end of the side of the movable base 3 away from the first hinge groove 21 has a second hinge groove 31, and the secondary umbrella rib 43 is hinged to the second hinge groove 31. The movable base 3 pulls the secondary umbrella rib 43 to control the opening and closing of the main umbrella rib 41 through the connecting part 42, so as to realize the unfolding and closing of the umbrella rib assembly 4.

[0028] Specifically, the horizontal distance between the first hinge groove 21 and the second hinge groove 31 is consistent with the width of the connecting part 42, so that the umbrella rib main rod 41, the connecting part 42 and the umbrella rib secondary rod 43 do not shift when the umbrella rib assembly 4 is unfolded, thereby improving the structural stability of the umbrella support.

[0029] Specifically, a sleeve 32 is provided on the inner side of the movable base 3. The inner wall of the sleeve 32 is slidably connected to the outer wall of the umbrella main rod 1, so that the umbrella rib assembly 4 runs smoothly during the unfolding and closing process, reducing operating resistance.

[0030] Specifically, such as Figure 4 The connecting part 42 shown is an "L" shaped structure. The longer side has a first hinge part 422, which is hinged to the end of the umbrella rib main rod 41 away from the first hinge groove 21; the shorter side has a second hinge part 423, which is hinged to the end of the umbrella rib auxiliary rod 43 away from the second hinge groove 31.

[0031] Specifically, a support rod 424 is provided at the end of the connecting part 42 away from the umbrella main rod 1. The support rod 424 extends outward along the length of the longer side of the connecting part 42 to support the umbrella surface, so that the umbrella surface is flatter when it is unfolded.

[0032] Specifically, such as Figure 5 The slot 421 shown is located at the lower part of the connecting part 42, blocking the direction of the umbrella rib main pole 41 from moving towards the lower part of the connecting part 42. This provides support for the umbrella rib main pole 41 in the unfolded state, preventing the umbrella rib main pole 41 from sagging or deforming due to external forces. The arc-shaped contour of the slot 421 fits the umbrella rib main pole 41, enhancing the fit between the connecting part 42 and the umbrella rib main pole 41, and preventing relative offset between the connecting part 42 and the umbrella rib main pole 41. This improves the load-bearing capacity and stability of the connection between the connecting part 42 and the umbrella rib main pole 41 in the unfolded state of the umbrella assembly 4.

[0033] Specifically, the bracket structure 431 extends towards the connecting part 42 from the side near the connecting part 42, and is provided with a ramp 432. When the umbrella rib assembly 4 is unfolded, it forms a ramp with the lower part of the connecting part 42, thereby limiting the connection between the connecting part 42 and the umbrella rib sub-rod 43. When strong winds or other external forces impact the position of the connecting part 42, the ramp 432 bears the pressure of the connecting part 42 moving downward, while the connecting part 42 is simultaneously supported by the slot 421. At this time, the connecting part 42 is doubly limited and fixed, thereby preventing the umbrella rib sub-rod 43 from overturning under the action of external forces, and further improving the overall stability and deformation resistance of the umbrella frame.

[0034] During use, the user holds the main umbrella pole 1 and controls the movable base 3 to slide upward along the main umbrella pole 1, causing the umbrella rib auxiliary pole 43 to move upward. At the same time, the main umbrella rib pole 41 is pulled open by the connecting part 42. After opening, the slot 421 at the lower part of the connecting part 42 is tightly engaged with the pole body of the main umbrella rib pole 41, and the lower plane of the connecting part 42 abuts against the inclined platform 432 of the mounting structure 431. At this time, when encountering strong winds or other external forces, the inclined platform 432 will bear the force of the umbrella surface on the connecting part 42, and the cooperation between the slot 421 and the main umbrella rib pole 41 will also provide support for the umbrella rib assembly 4. At this time, the connecting part 42 is doubly limited and fixed, thereby preventing the umbrella rib auxiliary pole 43 from overturning under the action of external forces, and improving the overall stability and deformation resistance of the umbrella frame. After use, the user controls the movable base 3 to slide downward along the main umbrella pole 1, causing the umbrella rib auxiliary pole 43 to move downward. At the same time, the main umbrella rib pole 41 is pulled closed by the connecting part 42, completing the umbrella frame retraction.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
