Description

Technical Field

[0001] This utility model relates to the technical field of umbrellas, specifically an umbrella tail cap structure and an umbrella. Background Technology

[0002] Umbrellas, as everyday tools for rain and sun protection, typically consist of an umbrella canopy, ribs, handle, and control components. The handle, as the core component for gripping and support, usually has a cap at its end, known as the umbrella tail cap (or handle tail cap). In existing technology, the main functions of the umbrella tail cap include: firstly, protecting the internal structure of the handle by covering connecting screws, telescopic mechanism slots, and other components to prevent dust and rainwater from directly intruding and causing corrosion or jamming.

[0003] However, in the current industry, umbrella canopies are usually made of one piece, with a sewing allowance left on the side edges of each piece. The sides of adjacent pieces are sewn together one by one to form a whole, ultimately forming an umbrella canopy structure that can cover the umbrella ribs. Currently, the top canopy and the tail cap are connected by threads. If a one-piece umbrella canopy is to be replaced, if the middle of the umbrella canopy is not punched through, the threaded connection of the tail cap to the top canopy will wear down the umbrella canopy. If the threaded connection is not punched through, it will wear down the umbrella fabric. Furthermore, because the threaded part is high, the top of the umbrella canopy will be pulled up, thus affecting the opening of the umbrella. If the middle of the umbrella canopy is punched through, water may leak in the punched part during use.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application proposes a tail cap structure for an umbrella and an umbrella.

[0006] Firstly, a tail cap structure for an umbrella employs the following technical solution:

[0007] An umbrella tail cover structure includes an upper nest and an umbrella tail cover. An installation ring is provided on the upper nest, and a fastening ring is provided on the side of the umbrella tail cover near the upper nest. The inner sidewall of the fastening ring is tightly fitted and abuts against the outer sidewall of the installation ring.

[0008] Preferably, the outer wall of the mounting ring is provided with a groove for the insertion of the fitting ring.

[0009] Preferably, the height of the umbrella tail cover is 2-3cm.

[0010] Preferably, the portion of the umbrella tail cover that contacts the umbrella fabric is an arc surface, and the sidewall of the annular groove at the groove opening is also an arc surface.

[0011] Preferably, the umbrella tail cover is hollow inside.

[0012] Preferably, the umbrella tail cover has a cross-shaped reinforcing rib in its hollow interior.

[0013] Preferably, the umbrella tail cover is tapered, and the fitting ring is located at the end of the umbrella tail cover with a larger cross-sectional area.

[0014] Secondly, an umbrella adopts the following technical solution:

[0015] An umbrella, including the aforementioned umbrella tail cap structure.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] When installing the tail cap of the umbrella, first place the center part of the canopy on the upper housing, then align the tail cap with the mounting ring of the upper housing so that the fitting ring below the tail cap fits onto the mounting ring. Through the tight fit between the fitting ring and the mounting ring, the tail cap is securely installed on the upper housing. At this time, the canopy will be pressed between the inner wall of the fitting ring and the outer wall of the mounting ring, preventing the canopy from shifting. Compared with the threaded connection between the upper housing and the tail cap, and the method of punching through the canopy, this design method does not require punching through the canopy, which can minimize the leakage and also prevent the canopy from being damaged during the installation of the tail cap.

[0024] 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 scope of protection of the present utility model.

[0025] This application discloses a tail cap structure for an umbrella.

[0026] Reference Figures 1 to 4 The umbrella tail cover structure includes an upper canopy 1 and a tail cover 2. Specifically, the lower side of the upper canopy 1 is used for the installation of umbrella ribs and umbrella shaft. An installation ring 11 is provided on the upper side of the upper canopy 1. The installation ring 11 is circular and is coaxially arranged with the upper canopy 1. The tail cover 2 is installed on the upper side of the upper canopy 1. A fitting ring 21 is provided on the side of the tail cover 2 near the upper canopy 1. The fitting ring 21 is also circular and is used to cooperate with the installation ring 11. The inner wall of the fitting ring 21 is used to fit tightly against the outer wall of the installation ring 11. Therefore, with the cooperation of the fastening ring 21 and the mounting ring 11, the umbrella tail cover 2 can be firmly installed on the upper nest 1. So, during the installation of the umbrella tail cover, the umbrella canopy is first installed to the predetermined position of the upper nest 1, and then the umbrella tail cover 2 is pressed down so that the fastening ring 21 and the mounting ring 11 are tightly fitted together. At this time, the umbrella canopy will be stuck between the fastening ring 21 and the mounting ring 11, thus realizing the installation of the umbrella canopy. This design method does not require the umbrella canopy to be pierced, thus avoiding water leakage problems as much as possible, and it can also avoid the damage to the umbrella canopy caused by threaded installation.

[0027] In some embodiments, in order to improve the installation strength of the umbrella tail cover 2, an annular groove 12 is provided on the outer side wall of the mounting ring 11. The annular groove 12 is coaxially arranged with the mounting ring 11. The side of the annular groove 12 near the upper nest 1 communicates with the upper side surface of the upper nest 1. The annular groove 12 is used for the insertion of the fitting ring 21. When the fitting ring 21 is inserted into the annular groove 12, the fitting ring 21 is restricted by the side wall of the annular groove 12 and the upper side surface of the upper nest 1, respectively, to prevent the fitting ring 21 from detaching from the mounting ring 11, so as to minimize the possibility of the umbrella tail cover 2 detaching from the upper nest 1.

[0028] In some embodiments, in order to reduce wear at the contact points between the umbrella fabric and the upper nest 1 and the umbrella tail cover 2, the contact points between the umbrella tail cover 2 and the umbrella fabric are set as arc surfaces, that is, the outer sidewalls of the fastening ring 21 are all set as arc surfaces, and the sidewalls at the groove opening of the ring groove 12 are also set as arc surfaces. Therefore, when the umbrella fabric is engaged with the fastening ring 21 and the ring groove 12, the umbrella fabric minimizes contact with sharp surfaces to avoid damage to the umbrella fabric.

[0029] In some embodiments, the height of the umbrella tail cap 2 is set to 2-3cm, so that when the umbrella tail cap structure is in use, the overall length of the umbrella is not too different, making it convenient to use and carry.

[0030] In some embodiments, the interior of the umbrella tail cover 2 is hollow. The hollow structure reduces the weight of the umbrella tail cover 2. At the same time, a cross reinforcing rib 3 is provided inside the umbrella tail cover 2 to enhance the structural strength of the umbrella tail cover 2, improve the deformation resistance of the umbrella tail cover 2, and strengthen the firmness of the umbrella tail cover 2 so that the umbrella tail cover 2 does not deform when installed on the upper nest 1.

[0031] In addition, in some embodiments, the umbrella tail cover 2 is cone-shaped, and the cross-sectional area of ​​the umbrella tail cover 2 on the side closer to the upper nest 1 is larger than the cross-sectional area on the side farther away from the upper nest 1. The cone-shaped umbrella tail cover 2 can effectively guide airflow during use (especially in headwinds), reduce air resistance, make the umbrella easier to hold and control, reduce hand stress, and the cone-shaped structure can disperse external forces (such as the impact force when the umbrella falls) to the whole umbrella tail cover 2, reduce local stress concentration, and with the internal reinforcing ribs, can further improve structural stability and extend service life.

[0032] This application also discloses an umbrella, as shown in the embodiments. Figures 1 to 4 The umbrella includes the aforementioned umbrella tail cap structure. The umbrella in this embodiment also has the aforementioned beneficial effects, which will not be described in detail here. The umbrella of this utility model can be a manual umbrella or an automatic umbrella, that is, the umbrella tail cap structure of this utility model can be applied to manual umbrellas, automatic umbrellas, etc.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
