Description

Technical Field

[0001] The utility model belongs to the field of umbrella accessories, and in particular relates to a protective structure of an umbrella nest. Background Art

[0002] Umbrellas are a kind of daily necessities that people often use. Most umbrellas currently on the market are made of iron or aluminum alloy as umbrella frames, in which the ribs need to be inserted into the umbrella nest to form a supporting structure, and the umbrella nest and the ribs are bound with iron wire. In order to ensure that the ribs have enough rotation space during the opening and closing of the umbrella, the connecting section between the ribs and the umbrella nest is usually partially exposed from the umbrella nest when the umbrella is in the folded state, forming sharp protrusions that are very easy to rub the umbrella cloth or ribs; although the existing umbrellas are passivated on the protruding ribs, it still cannot completely solve the problem, and the umbrella cloth or ribs are still damaged during transportation or after long-term use; especially driven by the demand for smaller umbrellas, the tightness of umbrella folding is required to be higher, and the frequency of customer complaints caused by this kind of abrasion is also increasing, seriously affecting the customer experience.

[0003] To solve this problem, existing commercially available umbrellas use soft materials such as elastic cotton or cloth to manually pad the joints of the ribs and nests when leaving the factory. This method has the following disadvantages: first, it increases the labor cost of umbrella manufacturing; second, the elastic cotton or cloth is easy to fall off during daily use and cannot form long-term protection, so it usually only plays a protective role during transportation and will be discarded after arriving at the destination. The discarded protective materials become waste, which is not in line with the concept of environmental protection; third, after the protective material is removed or falls off, the joints of the ribs and nests are exposed, and the iron wire interfaces for binding the ribs are also exposed accordingly (some umbrella products will set a protective cover outside the iron wire interface, but there is still the problem of the protective cover being easy to fall off), lacking effective and long-term protection, and the product quality is easily damaged and there are safety hazards such as scratches. Utility Model Content

[0004] In order to solve the problem that the joint between the ribs and the umbrella nest of the existing umbrella is easy to rub the umbrella cloth or the ribs when the umbrella is folded, the utility model proposes a protective structure of the umbrella nest, which has the characteristics of simple structure, long-term protection and controllable manufacturing cost.

[0005] The utility model is realized by the following technical solutions:

[0006] The utility model proposes a protective structure of an umbrella nest, comprising a lower umbrella nest and an elastic protective sleeve, wherein the lower umbrella nest comprises a nest body and an extension section, the extension section is provided with a fixing structure for preventing the elastic protective sleeve from sliding down, the elastic protective sleeve is sleeved outside the nest body, and the lower end of the elastic protective sleeve is provided with a necking section matched with the fixing structure.

[0007] Based on the above technical scheme, by arranging a layer of elastic protective cover on the outer surface of the lower umbrella nest and cooperating with an anti-slipping fixed structure on the lower end of the protective cover and the extension section of the lower umbrella nest, when the umbrella is opened, it does not interfere with the outward expansion of the umbrella ribs and prevents the protective cover from sliding downward. When the umbrella is folded, the joint between the umbrella ribs and the nest body is completely wrapped in the protective cover, separated from the umbrella cloth and other umbrella ribs, thereby achieving an effective protective effect.

[0008] Furthermore, the extension section is externally threadedly connected with a sleeve to form the fixed structure, and the necked section of the elastic protective sleeve is clamped to the lower end of the nest body through the sleeve. This structure has good installation characteristics and is easy to simplify the processing technology.

[0009] Furthermore, a necking groove is provided at the connection between the extension section and the nest body. This structure does not require the addition of additional components and can be integrally formed when the lower nest body is manufactured, thereby saving some material usage.

[0010] Furthermore, the extension section is protruded below the nest body to set a limiting structure to form the fixed structure. This structure does not require additional components and can be integrally formed when the lower nest body is manufactured. It can also be directly repaired and used on the original lower umbrella nest manufacturing mold, and the modification cost is low.

[0011] Preferably, the limiting structure is a circle of annular protrusions arranged on the extension section.

[0012] Preferably, the limiting structure is a plurality of positioning protrusions or positioning protrusions arranged circumferentially around the extension section.

[0013] Furthermore, the necking section is formed by extending the lower end of the elastic protective sleeve inwardly, and the necking section is embedded in the fixed structure. The structure prevents the elastic protective sleeve from sliding down by shrinking the lower end of the elastic protective sleeve inwardly and embedding it in the necking groove to limit the position.

[0014] Furthermore, the necking section of the elastic protective sleeve is formed by extending the elastic protective sleeve downward, the inner diameter of the necking section is slightly larger than the outer diameter of the extension section, the necking section is sleeved on the extension section, and the necking section is wrapped in the sleeve to form a limit for the elastic protective sleeve.

[0015] Furthermore, the necking section of the elastic protective sleeve is formed by extending the elastic protective sleeve downward, the inner diameter of the necking section is slightly larger than the outer diameter of the extension section, the necking section is sleeved on the extension section, the necking section wraps the limiting structure, and the structure is wrapped on the limiting structure of the lower umbrella nest through the necking section. The necking section is stretched outward and generates an inward contraction force under the action of elastic force, thereby achieving the effect of preventing the elastic protective sleeve from sliding down.

[0016] Furthermore, the elastic protective cover is made of silicone, which has good softness and wear resistance, or the elastic protective cover is made of heat-shrinkable elastic materials such as PE and silicone rubber. This material can enlarge the size of the elastic protective cover before processing, which is convenient for reducing the difficulty of processing, and makes the processed elastic protective cover have better fit and aesthetics with the lower umbrella nest, which is also convenient for miniaturized storage of the umbrella.

[0017] Beneficial Effects

[0018] One of the above technical solutions has the following advantages or beneficial effects:

[0019] 1) By arranging a layer of elastic protective cover on the outer surface of the lower umbrella nest and cooperating with an anti-slipping fixing structure on the lower end of the protective cover and the extension section of the lower umbrella nest, when the umbrella is opened, the ribs will not be interfered with and the protective cover will not slide downward. When the umbrella is folded, the joint between the ribs and the nest body is completely wrapped in the protective cover and separated from the umbrella cloth and other ribs, thereby achieving an effective protection effect, especially for multi-fold umbrellas and umbrellas that pursue miniaturization, the effect is more significant.

[0020] 2) By setting the necking section of the elastic protective cover as a circle extending inward, and fixing it with the necking groove, sleeve or limiting structure on the lower umbrella nest, the structure is simple, the anti-slip effect is good, and the processability is good.

[0027] The present invention is further described in detail below in conjunction with the embodiments, but the implementation manner of the present invention is not limited thereto.

[0028] Embodiment 1

[0029] The present embodiment provides a protective structure of an umbrella nest, comprising a lower umbrella nest 100 and an elastic protective cover 200. The lower umbrella nest 100 comprises a nest body 101 and an extension section 102. The extension section 102 is provided with a fixing structure 10 for preventing the elastic protective cover 200 from sliding down. The elastic protective cover 200 is sleeved on the outside of the nest body 101. The lower end of the elastic protective cover 200 is provided with a necking section 20 matched with the fixing structure 10. The inner diameter of the necking section 20 can be between the outer diameter of the extension section 102 and the outer diameter of the nest body 101 to improve the convenience of manufacturing. The inner diameter of the necking section 20 can also be smaller than the outer diameter of the extension section 102 to increase the adhesion of the elastic protective cover 200 on the umbrella nest. The elastic protective cover 200 is made of a silicone material with good softness and wear resistance.

[0030] like Figure 1 As shown, the necking section 20 is a circle formed by the lower end of the elastic protective sleeve 200 extending inwardly, and the fixing structure 10 is a sleeve 12 connected to the external thread of the extension section 102. The necking section 20 is clamped at the lower end of the nest 101 by the sleeve 12 to prevent the elastic protective sleeve 200 from sliding down. The fixing structure 10 is specifically as follows: the extension section 102 is provided with an external thread at a position a certain distance from the lower end of the nest 101 and is threadedly connected with the sleeve 12, and an internal thread matching the external thread is provided in the sleeve 12. After the elastic protective sleeve 200 is sleeved on the lower umbrella nest 100, the necking section 20 wraps the lower end surface of the nest 101 and is clamped and fixed on the lower end surface of the nest 101 by the sleeve 12. This structure has good installation characteristics and a relatively simple processing technology. As a feasible implementation, the necking section 20 may also be formed by extending the lower end of the elastic protective sleeve 200 downward, and the necking section 20 is sleeved on the extending section 102 and wrapped in the sleeve.

[0031] Embodiment 2

[0032] This embodiment proposes a protective structure of an umbrella nest, which is different from the previous embodiment in that:

[0033] like Figure 2 As shown, the necking section 20 is a circle extending inward from the lower end of the elastic protective sleeve 200, and the fixed structure 10 is a circle of annular grooves formed at the connection between the extension section 102 and the nest body 101. The necking section 20 also correspondingly increases the extension amount into the necking groove 11. This structure does not require additional components and can be integrally formed when the lower nest body 101 is manufactured, thereby saving some material usage.

[0034] Embodiment 3

[0035] This embodiment proposes a protective structure of an umbrella nest, which is different from the previous embodiment in that:

[0036] The fixing structure 10 is a limiting structure 13 protruding from the extension section 102 below the nest body 101. The limiting structure 13 is a circle of annular protrusions provided on the extension section 102 or a plurality of positioning protrusions or positioning protrusions arranged circumferentially around the extension section 102. This structure does not require the addition of additional components and can be integrally formed when the lower nest body 101 is manufactured. It can also be directly used to repair the original mold for manufacturing the lower umbrella nest 100, and the modification cost is relatively low.

[0037] An implementation method based on the above technical solution is: Figure 3 As shown, the necking section 20 is a circle formed by the lower end of the elastic protective sleeve 200 extending inwardly, and an annular groove is formed between the limiting structure 13 and the nest body 101, and the necking section 20 is embedded in the annular groove to form a limit;

[0038] Another implementation method based on the above technical solution is: Figure 4 As shown, the necking section 20 of the elastic protective cover 200 is formed by extending the elastic protective cover 200 downward, and the necking section 20 is sleeved on the extension section 102 and wraps the limiting structure 13. The structure is wrapped on the limiting structure 13 of the lower umbrella nest 100 through the necking section 20. The necking section 20 is stretched outward and generates an inward contraction force under the action of elastic force, thereby preventing the elastic protective cover 200 from sliding down.

[0039] Embodiment 4

[0040] This embodiment proposes a protective structure of an umbrella nest, which is different from the previous embodiment in that:

[0041] The elastic protective cover 200 is made of heat-shrinkable elastic materials such as PE and silicone rubber. This material allows the elastic protective cover 200 to be appropriately enlarged in size during production so that the elastic protective cover 200 can be easily inserted into the lower umbrella nest 100, and the elastic protective cover 200 can be tightly fitted to the lower umbrella nest 100 through heat shrinkage, so that the durability and aesthetics are better.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the present invention.
