Description

Technical Field

[0001] This application relates to the field of umbrella technology, specifically to an umbrella honeycomb structure. Background Technology

[0002] The honeycomb structure of an umbrella, serving as the hub of the umbrella ribs, is an important component. Common honeycomb structures include an upper honeycomb and a lower honeycomb. The upper honeycomb is installed at the top of the center rod, while the lower honeycomb plays a significant role in the opening and closing of the umbrella.

[0003] Existing umbrellas have some inconveniences in their opening and closing operation. Traditional umbrellas have a button on the outside of the lower umbrella flap and an upper flap on the center stick. To open the umbrella, the lower umbrella flap needs to be moved upwards, and the upper flap locks it in place, keeping the umbrella open. However, to close the umbrella, the button needs to be located and pressed to release the lower umbrella flap. This traditional upper flap structure is directional, so when holding the umbrella, one needs to find the right direction and press the button downwards to close it. Sometimes, the force required to press the button is also quite large, making it difficult to close the umbrella easily and inconvenient to use.

[0004] Currently, there are also some push-pull honeycomb structures. Although they have improved in operation, the supporting structure of the applicable central rod has poor support, which affects the overall stability of the umbrella. Utility Model Content

[0005] Therefore, this application provides an umbrella honeycomb structure to solve the problems of inconvenient opening and closing or poor overall stability of existing umbrella honeycomb structures.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A honeycomb structure for an umbrella includes: an upper honeycomb, an outer sleeve, an inner sleeve, and a retaining ring. The upper honeycomb is installed at the top of the umbrella's central rod. The inner sleeve is fitted around the periphery of the central rod. The outer sleeve is fitted around the outside of the inner sleeve and moves along the central rod's axial direction with the inner sleeve.

[0008] The central rod includes an inner tube, a middle tube, and an outer tube that are sequentially sleeved together. A spring is connected to the upper end of the retaining ring, and the other end of the spring is located at the bottom of the upper honeycomb and is fixedly connected to the top of the inner tube. When the umbrella is opened, the inner tube, the middle tube, and the outer tube are distributed from top to bottom, and the retaining ring is located between the inner tube and the inner sleeve and moves along the axial direction of the inner tube.

[0009] The top of the outer tube is provided with four spaced-apart pull strips, which are divided into two groups of opposing first pull strips and second pull strips; the upper part of the first pull strip is provided with a snap-fit ​​hole, and the top inner wall of the first pull strip is provided with a first guide slope that slopes downward from the outside to the inside above the snap-fit ​​hole; the outer wall of the upper honeycomb is provided with a snap-fit ​​block that fits the snap-fit ​​hole, and the outer wall of the snap-fit ​​block is provided with a second guide slope that cooperates with the first guide slope;

[0010] The top of the inner sleeve is provided with a third pull bar and a fourth pull bar respectively corresponding to the positions of the two first pull bars. The upper parts of the third pull bar and the fourth pull bar are both open outward, and the open parts of the third pull bar and the fourth pull bar are respectively provided with a third guide slope and a fourth guide slope that cooperate with the first guide slope.

[0011] Optionally, there are two of each of the third and fourth pull strips, with the two third pull strips spaced apart on both sides of one locking block and the two fourth pull strips spaced apart on both sides of another locking block.

[0012] Optionally, the inner walls of both second pull bars are provided with limit blocks, and the inner walls of the second pull bars form a moving groove in the upper region of the limit blocks. The top of the inner sleeve is provided with a fifth pull bar corresponding to the position between the adjacent third and fourth pull bars. The outer wall of the fifth pull bar is provided with a protrusion, which can move up and down in the moving groove.

[0013] Optionally, the lower part of the inner sleeve is provided with a support portion for pushing the outer sleeve to move up and down.

[0014] Optionally, an anti-slip strip is provided at the lower part of the inner sleeve corresponding to the position below the support portion.

[0015] Optionally, the lower outer wall of the outer sleeve is provided with a first annular groove in the radial direction, and the upper outer wall of the upper honeycomb is provided with a second annular groove in the radial direction, wherein the first annular groove and the second annular groove are used to install the umbrella rib assembly.

[0016] Optionally, keyholes are provided on both sides of the lower part of the upper honeycomb.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] 1. Based on further analysis and research of existing technical problems, this application provides a honeycomb structure for an umbrella, including an upper honeycomb, an outer sleeve, an inner sleeve, a retaining ring, and a spring. The upper honeycomb is installed at the top of the umbrella's central rod, and the outer sleeve is fitted over the inner sleeve and moves axially along the central rod with the inner sleeve. This honeycomb structure, through the snap-fit ​​hole and the first guide slope on the first pull bar, and the snap-fit ​​block and the second guide slope on the upper honeycomb, enables the outer sleeve and the upper honeycomb to quickly achieve a locking function. Furthermore, it eliminates the need to distinguish directions during use, allowing for easy opening and closing of the umbrella, making it convenient to use. The structural design of the central rod, with the outer diameters of the inner tube, middle tube, and outer tube increasing sequentially, allows the thicker outer tube at the bottom to withstand greater external forces, improving the overall support and stability of the umbrella. The retaining ring, with its outer diameter matching that of the outer tube, ensures stable movement between the inner tube and the inner sleeve, effectively supporting the inner sleeve and preventing it from detaching from the outer sleeve. This enhances the structural stability of the umbrella, prevents swaying during use, and improves the safety and reliability of the umbrella.

[0019] 2. The lower part of the inner sleeve of this application is provided with anti-slip strips, which not only play an anti-slip role, but also improve the convenience and safety of pushing and pulling operation, and at the same time play a decorative role in the overall structure of the umbrella.

[0020] 3. This application achieves the guiding and limiting functions of the inner sleeve during its up-and-down movement by setting a limiting block and a moving groove on the inner wall of the second pull bar, and setting a fifth pull bar and a protrusion on the top of the inner sleeve. The cooperation of the limiting block and the moving groove ensures the stable movement of the inner sleeve, prevents it from excessive displacement or falling off, and improves the overall stability, safety and reliability of the umbrella.

[0041] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0043] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0044] One embodiment of this application provides an umbrella honeycomb structure, such as... Figures 1-14 As shown, it includes: an upper honeycomb 1, an outer sleeve 2, an inner sleeve 3, a retaining ring 4, and a spring 5. The upper honeycomb 1 is installed at the top of the umbrella's central rod 6. Both the outer sleeve 2 and the inner sleeve 3 are hollow cylindrical structures. The inner sleeve 3 is fitted around the outer periphery of the central rod 6 and can move along the axial direction of the central rod 6. The outer sleeve 2 is fitted around the outer periphery of the inner sleeve 3 and moves along the axial direction of the central rod 6 with the inner sleeve 3.

[0045] like Figure 13 As shown, the central rod 6 includes an inner tube 61, a middle tube 62, and an outer tube 63 that are sequentially connected. One end of the spring 5 is connected to the upper end of the retaining ring 4, and the other end of the spring 5 is located at the bottom of the upper honeycomb 1 and is fixedly connected to the top of the inner tube 61. When the umbrella is opened, the inner tube 61, the middle tube 62, and the outer tube 63 are arranged in a top-to-bottom distribution structure. The outer diameters of the upper inner tube 61, the middle tube 62, and the lower outer tube 63 increase sequentially. The outer tube 63, which is thicker at the bottom, can withstand greater external forces, thus improving the overall support of the umbrella. The retaining ring 4 is located between the inner tube 61 and the inner sleeve 3 and moves along the axial direction of the inner tube 61. At the same time, the outer diameter of the retaining ring 4 is the same as the outer diameter of the outer tube 63.

[0046] like Figures 6-12As shown, the top of the outer sleeve 2 is provided with four spaced-apart pull strips, with notches or vertical slots formed between adjacent pull strips. The four pull strips are arranged in pairs facing each other. One pair of facing pull strips is designated as the first pull strip 21, and the other pair is designated as the second pull strip 22. A snap-fit ​​hole 211 is provided on the upper part of the first pull strip 21, and a snap-fit ​​block 11 adapted to the snap-fit ​​hole 211 is provided on the outer wall of the upper honeycomb 1. A first guide is also provided on the top inner wall of the first pull strip 21 above the snap-fit ​​hole 211. The inclined surface 212 is a first guide inclined surface that slopes downward from the outside to the inside and is used to guide the snapping action of the snapping block 11. The outer wall of the snapping block 11 is provided with a second guide inclined surface 111, which cooperates with the first guide inclined surface 212. When the outer sleeve 2 moves upward, the first pull strip 21 of the outer sleeve 2 and the snapping block 11 of the upper honeycomb 1 interact with each other, so that the first guide inclined surface 212 slides along the first guide inclined surface 212, and the snapping block 11 can be smoothly snapped into the snapping hole 211 to achieve the locking function.

[0047] The top of the inner sleeve 3 is provided with a third pull bar 31 and a fourth pull bar 32 corresponding to the positions of the two first pull bars 21. The upper parts of the third pull bars 31 and the fourth pull bars 32 are both open outwards, and the open portions of the third pull bars 31 and the fourth pull bars 32 are respectively provided with a third guide slope 311 and a fourth guide slope 321 that cooperate with the first guide slope 212. Specifically, the top of the inner sleeve 3 is symmetrically provided with two third pull bars 31 and two fourth pull bars 32. The two third pull bars 31 are spaced apart on both sides of one snap-fit ​​block 11, and the two fourth pull bars 32 are spaced apart on both sides of another snap-fit ​​block 11. The upper parts of the third pull bars 31 and the fourth pull bars 32 are both open outwards. The open portion of the third pull bar 31 is provided with a third guide slope 311 that cooperates with the first guide slope 212, and the open portion of the fourth pull bar 32 is provided with a fourth guide slope that cooperates with the first guide slope 212. 321; When the umbrella is closed, the open portions of the third pull bar 31 and the fourth pull bar 32 at the top of the inner sleeve 3 are at the bottom of the first guide slope 212 of the outer sleeve 2; as the outer sleeve 2 moves upward, the third pull bar 31 and the fourth pull bar 32 gradually open outward along the outer sleeve 2 under the action of the guide slope; when the outer sleeve 2 is engaged with the upper honeycomb 1, the third pull bar 31 and the fourth pull bar 32 open to a certain angle, forming a stable support structure to ensure that the umbrella can be opened smoothly and remain stable; when the umbrella needs to be closed, by pulling the inner sleeve 3 downward, the third pull bar 31 and the fourth pull bar 32 continue to move downward under the action of the guide slope. At this time, the open portions of the third pull bar 31 and the fourth pull bar 32 will open the first pull bar 21, so that the engaging block 11 of the upper honeycomb 1 disengages from the engaging hole 211 of the first pull bar 21. After the engaging block 11 disengages, the umbrella unlocks and the closing action is achieved.

[0048] The structural design of the central rod 6 improves the overall support of the umbrella by increasing the outer diameter of the inner tube 61, the middle tube 62 and the outer tube 63 in sequence. The design of the retaining ring 4 ensures the stable movement of the retaining ring 4 between the inner tube 61 and the inner sleeve 3 by having the same outer diameter as the outer tube 63, while supporting the inner sleeve 3, which enhances the structural stability of the umbrella, prevents parts from falling off, and thus improves the safety and reliability of the umbrella.

[0049] The aforementioned retaining ring 4 serves two specific purposes: First, it stabilizes the umbrella and prevents swaying. When the umbrella is open, under the elastic force of the spring 5, the retaining ring 4 is pushed into the gap between the lower middle part of the outer sleeve 2 and the inner tube 61 of the center rod 6. This positioning effectively limits the swaying amplitude of the umbrella and reduces the swaying arc caused by external forces during use. In this way, the retaining ring 4 ensures the stability of the umbrella during use, prevents it from falling due to excessive swaying, and improves the safety of umbrella use. 1. Safety and reliability; 2. Supporting the inner sleeve 3 to prevent parts from falling off: When the retaining ring 4 is pushed to the designated position, it can hold the inner sleeve 3, so that the inner sleeve 3 and the outer sleeve 2 fit tightly together, effectively preventing the third pull strip 31 and the fourth pull strip 32 from falling to the side closer to the inner tube 61. If the third pull strip 31 and the fourth pull strip 32 fall off, the umbrella will not be able to open normally. The retaining ring 4, by supporting the inner sleeve 3, ensures the stable position of the third pull strip 31 and the fourth pull strip 32, thereby ensuring that the umbrella maintains a good working condition and will not fall off easily.

[0050] Preferably, the inner walls of both second pull bars 22 are provided with limit blocks 221, and the inner walls of the second pull bars 22 form a moving groove 222 in the upper region of the limit blocks 221. The top of the inner sleeve 3 is provided with a fifth pull bar 33 at the position between the adjacent third pull bar 31 and the fourth pull bar 32. The outer wall of the fifth pull bar 33 is provided with a protrusion 331, which can move up and down in the moving groove 222.

[0051] Preferably, the lower part of the inner sleeve 3 is provided with a support part 34 for pushing the outer sleeve 2 to move up and down.

[0052] More preferably, the lower part of the inner sleeve 3 is provided with an anti-slip strip 35 corresponding to the position below the support part 34, which serves to prevent slipping, facilitate push-pull operation, and also serve a decorative function for the overall structure.

[0053] Preferably, the lower outer wall of the outer sleeve 2 is provided with a first annular groove 23 in the radial direction, and the upper outer wall of the upper honeycomb 1 is provided with a second annular groove 12 in the radial direction. The first annular groove 23 and the second annular groove 12 are used to install the umbrella rib assembly.

[0054] Preferably, the lower part of the upper honeycomb 1 is provided with locking holes 13 on both sides, and the upper honeycomb 1 is installed on the inner tube 61 of the middle rod 6 through the locking holes 13 on both sides.

[0055] The operating principle of the above embodiments:

[0056] When opening the umbrella, push the inner sleeve 3 upwards to its position. The supporting part 34 on the inner sleeve 3 pushes the outer sleeve 2 upwards, causing the outer sleeve 2 to move upwards synchronously. The first guide slope 212 at the top of the first pull bar 21 contacts the second guide slope 111 of the snap-fit ​​block 11 on the outer wall of the upper honeycomb 1. Continue to push the inner sleeve 3 upwards, so that the snap-fit ​​block 11 snaps into the snap-fit ​​hole 211 at the top of the first pull bar 21, thereby locking the outer sleeve 2 and opening the umbrella. At this time, when the umbrella is in the open state, under the elastic force of the spring 5, the retaining ring 4 is pushed into the gap between the lower middle part of the outer sleeve 2 and the inner tube 61 of the middle rod 6, reducing the swing arc of the umbrella during use and preventing the umbrella from falling.

[0057] When closing the umbrella, pull the inner sleeve 3 downwards. Under the interaction of the third guide slope 311 on the third pull bar 31 and the fourth pull bar 32 with the first guide slope 212 at the top of the first pull bar 21, the open parts on the third pull bar 31 and the fourth pull bar 32 are squeezed downwards, causing the open parts of the third pull bar 31 and the fourth pull bar 32 to open the corresponding first pull bar 21. Then the snap block 11 on the upper honeycomb 1 will disengage from the snap hole 211 at the top of the first pull bar 21, thus unlocking the umbrella and closing it. Subsequently, the outer sleeve 2 and the inner sleeve 3 continue to move downwards, returning to the position of the outer tube 63 of the middle rod 6.

[0058] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
