Description

Technical Field

[0001] This utility model relates to the field of umbrellas, and more specifically, to an opening and closing structure for an umbrella. Background Technology

[0002] Umbrellas are widely used in daily life and various outdoor activities as a common tool for sun and rain protection. Traditional umbrella opening and closing structures are typically quite simple, generally using a fixed-length center pole with elastic tabs near the top and bottom. The umbrella opens and closes by engaging these tabs with a honeycomb-like mechanism. However, in practice, it has been found that the fixed length of the center pole prevents users from adjusting the umbrella height according to different usage scenarios or personal needs, making it extremely inconvenient when facing varying sun protection requirements or space constraints. Furthermore, the tabs complicate the opening and closing structure, requiring the embedding of elastically extendable tabs within the center pole, increasing production costs and reducing safety during use. Utility Model Content

[0003] In view of this, the present invention provides an umbrella opening and closing structure with an adjustable umbrella rod length that is simple in structure, safe to use, and easier to unlock.

[0004] The objective of this utility model is achieved through the following technical solution: An umbrella opening and closing structure includes: a central rod and a honeycomb; The middle rod includes a main rod body and a secondary rod body, the main rod body being retractably inserted into the secondary rod body; the main rod body is provided with a first limiting port, and the secondary rod body is provided with at least two second limiting ports spaced apart along its axial direction; The honeycomb includes a sleeve and a buckle, both of which are slidably fitted onto the central rod. The buckle is elastically engaged with the sleeve and has radial elastic movement capability. The inner side of the buckle is provided with a radially protruding limiting block, which can selectively engage with the first limiting port or any one of the second limiting ports.

[0005] In the above technical solution, the main rod body expands and contracts within the secondary rod body, and multiple second limiting ports are axially distributed on the secondary rod body, realizing a multi-level and precise adjustment function for the length of the central rod. Users can flexibly adjust the overall length of the umbrella according to their own height, usage habits (such as hand height, hanging requirements) or specific scenarios (such as avoiding obstacles, adapting to different seat heights), significantly improving the comfort and convenience of use.

[0006] Furthermore, the honeycomb design features an automatic elastic locking function. During sliding, the limiting block can slide to either the first or second limiting port. When the sleeve slides to the target position, corresponding to the open or closed state, the elastic force of the buckle will cause the limiting block to automatically and reliably engage with the preset first limiting port (usually corresponding to the fully open state) or any of the second limiting ports (corresponding to the closed state). This elastic locking method provides clear tactile feedback and a secure mechanical lock, ensuring that the umbrella will not accidentally slide or loosen when open or closed, thus improving safety and reliability.

[0007] Optionally, in one possible implementation, the outer periphery of the main rod is provided with an elastic limiting bead, which can be squeezed into the interior of the main rod; the auxiliary rod is provided with limiting holes matching the number of the second limiting ports, and the elastic limiting bead can be engaged in any of the limiting holes.

[0008] In the above technical solution, when adjusting the extension and retraction length of the main rod, the user only needs to apply a certain axial force to the main rod while pressing the elastic limiting bead, causing the elastic limiting bead to retract into the secondary rod, thus allowing the main rod to extend and retract freely. During extension and retraction, the elastic limiting bead will instantly spring into the limiting hole under its own elastic force, producing a distinct "click" sound and a tactile feedback, thereby completing the adjustment of the middle rod length. The operation is simple and convenient.

[0009] Alternatively, in one possible implementation, the spacing between two adjacent limiting holes is the same as the spacing between two adjacent second limiting ports.

[0010] In the above technical solution, the spacing between adjacent limiting holes on the auxiliary rod is designed to be exactly the same as the spacing between adjacent second limiting ports. This ensures the perfect coordinated operation of the main rod's elastic limiting bead locking and the honeycomb buckle limiting block locking, eliminating the risk of misalignment between the two levels of locking. It ensures that after adjusting the length of the central rod, the honeycomb can be accurately and stably engaged in the corresponding second limiting port, thus ensuring that the umbrella can be completely closed.

[0011] Optionally, in one possible implementation, the first limiting port and the second limiting port have the same structure, both being a hole-like structure or a groove-like structure.

[0012] In the above technical solution, the hole-shaped or groove-shaped structure greatly facilitates processing. Only one set of molds for forming hole-shaped or groove-shaped limiting openings needs to be designed, which can simultaneously meet the production requirements of the first limiting opening and the second limiting opening, thereby reducing the development cost and design cycle of the mold.

[0013] Optionally, in one possible implementation, the inner wall of the sleeve is provided with a mounting groove, and the buckle is engaged in the mounting groove.

[0014] In the above technical solution, the mounting groove serves to position and limit the ring-shaped buckle, ensuring it is accurately installed in the predetermined position during assembly and preventing it from detaching from the sleeve. The buckle and sleeve are tightly connected through the mounting groove, forming an organic whole. During umbrella use, as the honeycomb slides along the central rod, the buckle and sleeve move synchronously, preventing separation or uncoordinated movement.

[0015] Optionally, in one possible implementation, the inner wall of the mounting groove is further provided with an extension groove, the extension groove extending radially outward along the central rod, and the outer side of the buckle is provided with a buckle, the buckle engaging in the extension groove.

[0016] In the above technical solution, the snap-fit ​​design of the extension groove and the buckle further strengthens the fixation of the annular buckle in the honeycomb structure. When the umbrella is opened or closed, the buckle engages within the extension groove, effectively preventing accidental radial displacement of the annular buckle. Furthermore, during assembly, the snap-fit ​​between the buckle and the extension groove provides assembly workers with clear assembly instructions, ensuring assembly accuracy.

[0017] Alternatively, in one possible implementation, the buckles are two located on opposite sides of the buckle, and the extension slots are two corresponding to the two buckles.

[0018] In the above technical solution, the two buckles and the two extension grooves form a double snap-fit ​​structure, which further enhances the connection strength between the buckle and the sleeve. Compared with the combination of a single buckle and extension groove, the stability is significantly improved.

[0019] Optionally, in one possible implementation, the side wall of the sleeve is provided with a positioning hole communicating with the mounting groove, and a button connected to the buckle is provided in the positioning hole, the button being opposite to the limiting block.

[0020] In the above technical solution, a button is provided inside the positioning hole, connected to the annular buckle and opposite to the limiting block, which greatly facilitates the user's operation of opening and closing the umbrella. When the user wants to open or close the umbrella, they only need to press the button to easily change the locking state of the limiting block with the first or second limiting port.

[0021] Optionally, in one possible implementation, the buckle is elastically snapped onto the sleeve by a snap-fit ​​structure. The snap-fit ​​structure includes a positioning post located on the outside of the buckle and opposite to the limiting block, and an elastic member sleeved on the positioning post. One end of the elastic member abuts against the buckle, and the other end abuts against the inner wall of the sleeve.

[0022] In the above technical solution, the elastic element in the snap-fit ​​structure provides a continuous and stable locking force. When the limiting block snaps into the first or second limiting port, the elastic force of the elastic element helps to maintain a tight snap-fit ​​between the limiting block and the first or second limiting port. When the umbrella is opened or closed, whether subjected to slight shaking or a certain degree of external pulling, this stable locking force ensures that the honeycomb is fixed in position on the central rod, preventing accidental unlocking.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] Please refer to Figures 1-5 .

[0033] This embodiment provides an umbrella opening and closing structure, including: a central rod 1 and a honeycomb 2; the central rod 1 includes a main rod body 11 and a secondary rod body 12, the main rod body 11 being retractably inserted into the secondary rod body 12; the main rod body 11 is provided with a first limiting port 111, and the secondary rod body 12 is provided with at least two second limiting ports 121 spaced apart along its axial direction; the honeycomb 2 includes a sleeve 21 and a buckle 22, both of which are slidably fitted onto the central rod 1; the buckle 22 is elastically engaged with the sleeve 21, and the buckle 22 has radial elastic movement capability, and the inner side of the buckle 22 is provided with a radially protruding limiting block 221, which can selectively engage with the first limiting port 111 or any one of the second limiting ports 121.

[0034] Specifically, both the main rod 11 and the secondary rod 12 are hollow structures, and can be circular or polygonal. In this embodiment, a polygonal structure is preferred, ensuring that the main rod 11 does not rotate relative to the secondary rod 12 during sliding. This embodiment has two second limiting ports 121, allowing for two-stage adjustment of the length of the central rod 1. When the rod is in a retracted state, and the umbrella is closed, the honeycomb 2 will engage in the lower second limiting port 121. Conversely, when the rod is in an extended state, and the umbrella is closed, the honeycomb 2 will engage in the upper second limiting port 121.

[0035] This embodiment achieves a multi-level, refined length adjustment function for the middle rod 1 through the telescopic cooperation of the main rod 11 within the secondary rod 12 and the axial distribution of multiple second limiting ports 121 on the secondary rod 12. Users can flexibly adjust the overall length of the umbrella according to their own height, usage habits (such as hand holding height, hanging needs) or specific scenarios (such as avoiding obstacles, adapting to different seat heights), significantly improving the comfort and convenience of use.

[0036] Furthermore, the honeycomb 2 features an automatic elastic locking function. During sliding, the limiting block 221 can slide to either the first limiting port 111 or the second limiting port 121. When the sleeve 21 slides to the target position, corresponding to the open or closed umbrella state, the elastic force of the buckle 22 will cause the limiting block 221 to automatically and reliably engage with the preset first limiting port 111 (usually corresponding to the fully open umbrella state) or any of the second limiting ports 121 (corresponding to the closed umbrella state). This elastic locking method provides clear tactile feedback and a stable mechanical lock, ensuring that the umbrella will not accidentally slide or loosen when open or closed, thus improving safety and reliability.

[0037] Please refer to Figure 1 In this embodiment, an elastic limiting bead 112 is fitted around the outer periphery of the main rod 11, and the elastic limiting bead 112 can be squeezed into the interior of the main rod 11. The secondary rod 12 is provided with limiting holes 122 matching the number of second limiting ports 121, and the elastic limiting bead 112 can be engaged in any of the limiting holes 122. A circular hole is opened on the side wall of the main rod 11, and the diameter of the circular hole is smaller than the diameter of the elastic limiting bead 112. The elastic limiting bead 112 is squeezed and abutted against the circular hole by the action of a spring, so that part of the elastic limiting bead 112 protrudes from the circular hole.

[0038] When adjusting the extension and retraction length of the main rod 11, the user only needs to apply a certain axial force to the main rod 11 while pressing the elastic limiting bead 112, causing the elastic limiting bead 112 to retract into the secondary rod 12, thus allowing the main rod 11 to extend and retract freely. When the main rod 11 extends and retracts, the elastic limiting bead 112 will instantly spring into the limiting hole 122 under its own elastic force, producing a distinct "click" sound and a tactile jolt, thereby completing the adjustment of the length of the middle rod 1. The operation is simple and convenient.

[0039] It should be noted that the distance between two adjacent limiting holes 122 is the same as the distance between two adjacent second limiting openings 121. Understandably, the honeycomb 2 moves a fixed distance when the umbrella is closed. Therefore, when the main rod 11 extends or retracts within the secondary rod 12, the position of the honeycomb 2 on the secondary rod 12 changes. Thus, multiple second limiting openings 121 need to be provided on the secondary rod 12 to cooperate with the honeycomb 2. The distance between two adjacent second limiting openings 121 needs to be synchronized with the distance between two adjacent limiting holes 122 to ensure that the honeycomb 2 accurately engages within the corresponding second limiting opening 121 when the umbrella is closed.

[0040] Therefore, designing the spacing between adjacent limiting holes 122 on the auxiliary rod 12 to be exactly the same as the spacing between adjacent second limiting ports 121 ensures perfect coordination between the locking of the elastic limiting bead 112 of the main rod 11 and the locking of the limiting block 221 of the honeycomb 2 buckle 22. This eliminates the risk of misalignment between the two levels of locking and ensures that after adjusting the length of the middle rod 1, the honeycomb 2 can be accurately and stably engaged with the corresponding second limiting port 121, thus ensuring that the umbrella can be completely closed.

[0041] In this embodiment, the first limiting port 111 and the second limiting port 121 have the same structure, both being hole-shaped or groove-shaped structures. Specifically, the first limiting port 111 and the second limiting port 121 can be square holes or square grooves, punched out by stamping.

[0042] The hole-like or groove-like structure greatly facilitates processing. Only one set of molds for forming hole-like or groove-like limiting openings needs to be designed, which can simultaneously meet the production requirements of the first limiting opening 111 and the second limiting opening 121, reducing the development cost and design cycle of the mold.

[0043] Please refer to Figure 4 In this embodiment, the inner wall of the sleeve 21 is provided with a mounting groove 211, and the retaining ring 22 is engaged in the mounting groove 211. The mounting groove 211 has a ring-shaped structure and extends radially outward along the inner wall of the sleeve 21. The two opposite sides of the retaining ring 22 are two parallel straight edges, and the retaining ring 22 can be directly inserted into the mounting groove 211.

[0044] The mounting groove 211 positions and limits the annular buckle 22, ensuring it is accurately installed in the designated position during assembly and preventing it from detaching from the sleeve 21. The buckle 22 and sleeve 21 are tightly connected via the mounting groove 211, forming a unified whole. During umbrella use, as the honeycomb 2 slides along the central rod 1, the buckle 22 and sleeve 21 move synchronously, preventing separation or uncoordinated movement.

[0045] In addition, the inner wall of the mounting groove 211 is provided with an extension groove 212, which extends radially outward along the central rod 1. A buckle 222 is provided on the outer side of the retaining ring 22, and the buckle 222 engages within the extension groove 212. The buckle 222 has an inverted triangular cross-section. During installation, the mounting groove 211 compresses the inclined edge of the buckle 222, causing it to elastically deform until the buckle 222 engages within the extension groove 212. There are two buckles 222 located on opposite sides of the retaining ring 22, and two extension grooves 212 corresponding to the two buckles 222.

[0046] The snap-fit ​​design of the extension groove 212 and the buckle 222 further strengthens the fixation of the annular buckle 22 in the honeycomb 2. When the umbrella is opened or closed, the buckle 222 snaps into the extension groove 212, effectively preventing accidental radial displacement of the annular buckle 22. Furthermore, during assembly, the snap-fit ​​between the buckle 222 and the extension groove 212 provides clear assembly instructions for the assembly worker, ensuring assembly accuracy. The two buckles 222 and the two extension grooves 212 form a double snap-fit ​​structure, further enhancing the connection strength between the buckle 22 and the sleeve 21. Compared to the cooperation of a single buckle 222 and extension groove 212, the stability is significantly improved.

[0047] In this embodiment, the side wall of the sleeve 21 is provided with a positioning hole 213 communicating with the mounting groove 211. A button 223 connected to the retaining ring 22 is provided inside the positioning hole 213, and the button 223 is opposite to the limiting block 221. During installation, the retaining ring 22 is inserted into the mounting groove 211 through the positioning hole 213. When installation is complete, the button 223 is positioned exactly inside the positioning hole 213. The user can change the position of the retaining ring 22 by pressing the button 223.

[0048] A button 223 is provided inside the positioning hole 213, which is connected to the annular buckle 22 and is opposite to the limiting block 221, providing great convenience for the user to operate the opening and closing of the umbrella. When the user wants to open or close the umbrella, he / she can easily change the locking state of the limiting block 221 with the first limiting port 111 or the second limiting port 121 by simply pressing the button 223.

[0049] In this embodiment, the retaining ring 22 is elastically engaged with the sleeve 21 via a snap-fit ​​structure. The snap-fit ​​structure includes a positioning post 23 located on the outside of the retaining ring 22 and opposite to the limiting block 221, and an elastic element 24 sleeved on the positioning post 23. One end of the elastic element 24 abuts against the retaining ring 22, and the other end abuts against the inner wall of the sleeve 21. The elastic element 24 is a metal spring.

[0050] The elastic element 24 in the snap-fit ​​structure provides a continuous and stable locking force. When the limiting block 221 is engaged with the first limiting port 111 or the second limiting port 121, the elastic force of the elastic element 24 helps to maintain the tight engagement between the limiting block 221 and the first limiting port 111 or the second limiting port 121. When the umbrella is opened or closed, whether subjected to slight shaking or a certain degree of external pulling, this stable locking force ensures that the honeycomb 2 is fixed in position on the central rod 1, preventing accidental unlocking.
