Description

Technical Field

[0001] This utility model relates to the field of craft umbrella technology, specifically to an upper umbrella support that prevents loosening and cracking. Background Technology

[0002] The existing umbrella supports for craft umbrellas are injection molded. Although the umbrella support is only a small component of a craft umbrella, it plays an indispensable role in improving the functionality, aesthetics, and durability of the umbrella. It not only improves the user experience but also effectively extends the lifespan of the craft umbrella. However, the umbrella supports currently on the market have significant defects: the diameter of existing wooden umbrella poles inevitably varies during production and the growth of bamboo umbrella poles. This results in an either too tight or too loose fit with the umbrella support. If it is too tight, the umbrella support will crack, causing defects or even scrapping. If it is too loose, it will easily fall off, affecting subsequent processes. Companies with good quality control can keep the tolerances within a strict range, but this will inevitably increase the technical threshold and the scrap rate, thereby increasing costs. For general companies and natural materials, it is necessary to design an umbrella support that is resistant to loosening and cracking. Utility Model Content

[0003] The purpose of this invention is to provide an umbrella support that is resistant to loosening and cracking, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-loosening and crack-resistant upper umbrella support, comprising an upper umbrella support top, side supports, a fixing structure, and an upper umbrella support bottom, wherein a second vertical rib is fixedly connected to a through hole opened inside the upper umbrella support top; a first vertical rib is fixedly connected to a through hole opened inside the upper umbrella support bottom, and a second vertical rib is fixedly connected to the first vertical rib.

[0005] As a further technical solution of this utility model, the bottom of the upper umbrella support is fixedly connected to the fixed structure.

[0006] As a further technical solution of this utility model, a side support is fixedly connected to the top of the upper umbrella support.

[0007] As a further technical solution of this utility model, a fixing structure is fixedly connected to the top of the upper umbrella support.

[0008] As a further technical solution of this utility model, the side support is fixedly connected to the fixed structure.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: This anti-loosening and crack-resistant upper umbrella support, by setting a hole in the center of the upper umbrella support with a diameter larger than the maximum limit diameter of the umbrella pole, and setting a first vertical rib and a second vertical rib inside the hole, achieves high adaptability by utilizing the toughness of the upper umbrella support material itself and the compressibility of the wood and bamboo material of the umbrella pole. The inner diameter of the first vertical rib is equal to the basic diameter of the umbrella pole, reducing the expansion force of the umbrella pole. The inner diameter of the second vertical rib is smaller than the minimum limit diameter of the umbrella pole, serving as the main stress point to bear the expansion force and forming a tight fit with the umbrella pole. This upper umbrella support can effectively reduce assembly losses, allow for larger tolerances in umbrella pole manufacturing, eliminate rework caused by this, fundamentally solve the problems of loosening and cracking that occur during the assembly of the umbrella pole and the upper umbrella support, significantly improve the yield rate, and thus reduce production costs.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of an anti-loosening and crack-resistant upper umbrella support, comprising an upper umbrella support top 1, a side support 2, a fixing structure 3, and an upper umbrella support bottom 4. A second vertical rib 6 is fixedly connected to a through hole inside the upper umbrella support top 1, and a first vertical rib 5 is fixedly connected to a through hole inside the upper umbrella support bottom 4. The first vertical rib 5 is fixedly connected to the second vertical rib 6. The upper umbrella support bottom 4 is fixedly connected to the fixing structure 3. The side support 2 is fixedly connected to the upper umbrella support top 1. The side support 2 is fixedly connected to the upper umbrella support top 1.

[0016] Based on the above, the advantages of this utility model are as follows: A hole is provided in the center of the upper umbrella support, with a hole diameter larger than the maximum limit diameter of the umbrella pole. A first vertical rib 5 and a second vertical rib 6 are provided inside the hole. High adaptability is achieved by utilizing the inherent toughness of the upper umbrella support material and the compressibility of the wood and bamboo material of the umbrella pole. The inner diameter of the first vertical rib 5 is equal to the basic diameter of the umbrella pole, reducing the expansion force of the umbrella pole. The inner diameter of the second vertical rib 6 is smaller than the minimum limit diameter of the umbrella pole, serving as the main stress point to withstand the expansion force and forming a tight fit with the umbrella pole. The beveled opening at the bottom 4 of the upper umbrella support is to improve guidance and facilitate installation. Through these methods, assembly losses of the upper umbrella support can be effectively reduced, allowing for larger tolerances in umbrella pole manufacturing, eliminating rework caused by this, fundamentally solving the problems of loosening and cracking that occur during the assembly of the umbrella pole and the upper umbrella support, significantly improving the yield rate, and thus reducing production costs.
