Description

Technical Field

[0001] This utility model relates to the field of umbrella technology, and in particular to a double-material plastically molded umbrella rib structure and umbrella. Background Technology

[0002] As everyday tools for shielding from the sun and rain, the structural design of umbrellas directly affects the user experience and durability. Traditional umbrellas are mainly divided into two categories: folding umbrellas and straight-rib umbrellas. Folding umbrellas are assembled with their shafts, which have a certain degree of flexibility but lack strength. Straight-rib umbrellas are relatively simple to manufacture and have better strength than folding umbrellas, but they are less flexible.

[0003] In scenarios with unpredictable weather, users need to choose between folding umbrellas and straight umbrellas depending on the weather conditions, making carrying multiple umbrellas extremely inconvenient. Limited by the single-material structure of traditional umbrella poles, existing umbrellas struggle to simultaneously address the deficiencies in strength and toughness, leading to stagnation in the umbrella industry and failing to meet users' demands for comprehensive umbrella performance. Therefore, a rib structure that combines the strength of rigid materials with the toughness of flexible materials, and umbrellas utilizing this structure, are needed to solve the problems of existing technologies. Summary of the Invention

[0004] The purpose of this utility model is to provide a dual-material plastically molded umbrella rib structure and umbrella fitting, to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: The first aspect of this utility model provides a dual-material plastically molded umbrella rib structure, which consists of an inner layer and an outer layer covering the outside of the inner layer, wherein the inner layer is a soft material and the outer layer is a hard material.

[0005] Furthermore, both the inner and outer layers are manufactured by injection molding using a plastic molding process.

[0006] Furthermore, the umbrella rib structure is divided into folding umbrella ribs and a plurality of foldable support rods, wherein the folding umbrella ribs are used to support the support rods when unfolded.

[0007] Furthermore, a snap-fit ​​connection mechanism is provided between the folding umbrella rib and the support rod. When the folding umbrella rib supports the support rod in its unfolded state, the two are securely connected by the snap-fit ​​connection mechanism.

[0008] Furthermore, the buckle connection mechanism includes a slot formed in the support rod and a buckle provided in the folding umbrella rib; when the folding umbrella rib supports the support rod in its unfolded state, the buckle engages with the slot.

[0009] The second aspect of this utility model also provides an umbrella, which adopts the umbrella rib structure formed by plastic molding of two materials as described above.

[0010] The beneficial effects of this utility model are as follows: The umbrella rib structure of this utility model breaks through the performance limitations of traditional single-material umbrella ribs, taking into account the toughness of soft materials and the strength of hard materials, avoiding the problems of insufficient strength of folding umbrellas and poor toughness of straight-rib umbrellas, greatly improving the durability and adaptability of umbrella ribs, providing a more optimized technical solution for the umbrella industry, helping to enhance the industry's competitiveness and promote technological progress in the industry.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0022] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0023] The core objective of this application is to provide a dual-material plastically molded umbrella rib structure and umbrella. The umbrella rib structure, through the design of covering the inner soft material and the outer hard material, combined with specific connection and molding processes, achieves a dual improvement in the strength and toughness of the umbrella, while optimizing the unfolding and fixing effect of the umbrella rib, and improving the ease of use and product competitiveness.

[0024] Example 1 like Figure 1 and Figure 2As shown, this embodiment provides a dual-material plastically molded umbrella rib structure 1, which consists of an inner layer 101 and an outer layer 102 covering the outside of the inner layer 101. The inner layer 101 is made of a soft material, and the outer layer 102 is made of a rigid material, forming an integrated structure of a soft core and a rigid shell. The soft material of the inner layer 101 provides basic deformation capacity and toughness support for the umbrella rib, while the rigid material of the outer layer 102 forms a sturdy protective and load-bearing layer. The two layers are closely fitted and work together, so that when the umbrella rib is subjected to force, the inner layer 101 can buffer and disperse stress, and the outer layer 102 can resist external impact.

[0025] The umbrella rib structure 1 in this embodiment breaks through the performance limitations of traditional single-material umbrella ribs, taking into account the toughness of soft materials and the strength of hard materials. It avoids the problems of insufficient strength when folding umbrellas and poor toughness of straight-rib umbrellas, greatly improving the durability and adaptability of umbrella ribs. It provides a more optimized technical solution for the umbrella industry, helps to enhance the industry's competitiveness, and promotes technological progress in the industry.

[0026] In this embodiment, both the inner layer 101 and the outer layer 102 are manufactured using an injection molding machine through a plastic molding process. Specifically, both the inner layer 101 and the outer layer 102 are processed by an injection molding machine, and the injection molding process is completed in steps. When the outer layer 102 is injected, it is based on the already formed inner layer 101 to achieve precise coverage. First, a soft plastic material is injected into the injection molding machine, and after cooling, it forms the inner layer 101 structure. Then, through a secondary injection process, a rigid plastic material is injected into the same injection molding machine, so that the rigid material is evenly covered on the outside of the already formed inner layer 101, and finally solidified to form an integrated umbrella rib structure 1. Through the plastic molding injection process, it is ensured that the inner layer 101 and the outer layer 102 are tightly connected and evenly covered, avoiding delamination or peeling. The integrated molding process simplifies the production process, improves production efficiency, and at the same time ensures the dimensional accuracy and stability of the umbrella rib structure 1.

[0027] In this embodiment, see Figure 1 and Figure 4The umbrella rib structure 1 is functionally divided into two main components: a folding rib 11 and a plurality of foldable support rods 12. The folding rib 11 supports the unfolding of the support rods 12. Specifically, the folding rib 11 is movably connected to the support rods 12, serving as a support component for the support rods 12, allowing the support rods 12 to unfold or fold as the folding rib 11 is opened or closed. When the folding rib 11 is open, it provides the main support force, driving the plurality of support rods 12 to unfold synchronously, forming a support frame for the umbrella surface. When the folding rib 11 is folded, the support rods 12 can be folded and folded away from the outside of the folding rib 11, reducing the overall volume of the umbrella. By rationally dividing the functional components of the umbrella rib structure 1, the supporting function of the folding rib 11 is combined with the foldable characteristics of the support rods 12, ensuring the stability of the umbrella surface after unfolding while retaining the advantage of the folding umbrella being easy to carry, thus improving the practicality of the product.

[0028] In this embodiment, see Figure 3 and Figure 5 A snap-fit ​​connection mechanism is provided between the folding umbrella rib 11 and the support rod 12. When the folding umbrella rib 11 supports the support rod 12 in its unfolded state, the two are securely connected by the snap-fit ​​connection mechanism. This mechanism provides a fixing function for the movable connection between the folding umbrella rib 11 and the support rod 12, and is only secured when the support rod 12 is fully unfolded. Specifically, when the folding umbrella rib 11 drives the support rod 12 to unfold to a preset angle (i.e., the umbrella surface is fully open), the snap-fit ​​connection mechanism is automatically triggered and locked, securing the folding umbrella rib 11 and the support rod 12 to prevent the support rod 12 from folding accidentally during use. When storing, the locking state of the snap-fit ​​connection mechanism is released, and the support rod 12 can be folded and closed along the folding umbrella rib 11. The snap-fit ​​connection mechanism ensures the stability of the connection between the support rod 12 and the folding umbrella rib 11 after the support rod 12 is unfolded, avoiding the impact on the use effect due to the support rod 12 loosening after the umbrella surface is opened; the tightening and unlocking operations are convenient and do not affect the convenience of folding the umbrella.

[0029] In this embodiment, see Figure 3 and Figure 5The snap-fit ​​connection mechanism includes a snap-fit ​​21 on the folding umbrella rib 11 and a slot 22 on the support rod 12. When the folding umbrella rib 11 supports the support rod 12 and is unfolded, the snap-fit ​​21 and the slot 22 engage. Specifically, the snap-fit ​​21 is fixedly mounted on the folding umbrella rib 11, and the slot 22 is located at the corresponding position on the support rod 12. The slot 22 and the snap-fit ​​21 are structurally matched to form a precise engagement. During the unfolding of the support rod 12, the snap-fit ​​21 on the folding umbrella rib 11 gradually approaches the slot 22 of the support rod 12 as the support rod 12 moves. When the support rod 12 is fully unfolded, the snap-fit ​​21 is precisely embedded in the slot 22, and the folding umbrella rib 11 and the support rod 12 are secured through mechanical engagement. When folding is required, external force is applied to disengage the snap-fit ​​21 from the slot 22, and the support rod 12 can be folded freely. The precise engagement of the slot 22 and the buckle 21 ensures a secure connection. The structure is simple, reliable, and not easily damaged. The mechanical locking method requires no additional steps and is compatible with the unfolding and folding process of umbrellas, improving ease of use.

[0030] Example 2 This embodiment provides an umbrella that uses the above-described dual-material plastic-molded umbrella rib structure 1.

[0031] In this embodiment, the umbrella includes an umbrella pole, an umbrella rib structure 1, and an umbrella fabric. The umbrella rib structure 1 is movably connected to the umbrella pole, and can be unfolded or folded along the pole. The umbrella fabric covers and is fixed to the support rod 12 of the umbrella rib structure 1, forming a complete umbrella. During use, the umbrella pole drives the extension and retraction of the folding umbrella ribs 11, which in turn drives the expansion or folding of the support rod 12. After unfolding, the support rod 12 is secured by a snap-fit ​​connection mechanism, supporting the umbrella fabric to form a complete shelter space. The dual-layer material of the umbrella rib structure 1 works synergistically to resist external impacts and maintain structural stability.

[0032] The umbrella in this embodiment inherits the strength and toughness advantages of the dual-material plastic-molded umbrella rib structure 1, while also having the characteristics of convenient folding and stable unfolding. It solves the problem that traditional umbrellas are difficult to balance durability and portability, and improves the overall user experience and market competitiveness of the umbrella.
