Description

Technical Field

[0001] This utility model relates to the field of umbrella rib technology, specifically to an umbrella rib connection structure. Background Technology

[0002] Currently, most umbrella rib structures on the market use exposed or simply fixed hooks for securing the umbrella when closed. The connection between the hook and the rib lacks a dedicated storage or protective structure, leaving the hook in a naturally extended state after folding. Due to the lack of effective storage and restraint, the hook protrudes after folding, its sharp edges directly exposed. Furthermore, the connection method between the hook and the rib does not allow for retractable rotation adjustment. The protruding hook is prone to contact with the user's body, potentially causing scratches. Additionally, when the umbrella is folded, the hook can easily snag on the fabric, causing damage, fraying, and other issues, reducing the umbrella's lifespan and safety, and negatively impacting the user experience. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing an umbrella rib connection structure that solves at least one of the aforementioned technical problems. This structure has the advantages of being able to store and restrain the hooks, preventing scratches and cuts, and improving service life and safety.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an umbrella rib connection structure, comprising: an umbrella rib, and a pull rod hinged to the umbrella rib; the umbrella rib is provided with a receiving groove, and a mounting hole is provided through the receiving groove; one end of the pull rod is provided with a hook that hooks into the mounting hole, and the end of the hook is accommodated and movable within the receiving groove.

[0005] In a further embodiment of this invention, the receiving groove is an arc-shaped groove.

[0006] The present invention is further provided that the height of the receiving groove is at the same level as the end of the hook.

[0007] The present invention is further provided that the opening end of the receiving groove is rounded.

[0008] In a further embodiment of this invention, the umbrella rib and the receiving groove are integrally formed.

[0009] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, a receiving groove is provided on the umbrella rib, and an installation hole is provided through the middle of the receiving groove. One end of the pull rod is provided with a hook that hooks into the installation hole. The end of the hook passes through the installation hole and is accommodated in the receiving groove. The hook can move in the receiving groove. Therefore, the hook can be effectively stored and restrained, which can prevent scratches and cuts, avoid scratching the umbrella surface or injuring the user, and improve the service life and safety.

[0011] 2. When the umbrella ribs are retracted or unfolded, the pull rod rotates with the umbrella ribs, and the hook rotates relative to the receiving groove. The receiving groove is set as an arc-shaped groove, and the trajectory of the hook rotating with the pull rod is usually arc-shaped. The arc-shaped groove can match the movement path of the hook, reduce the friction or jamming between the hook and the inner wall of the receiving groove, make the pull rod rotate more smoothly, and avoid structural jamming or component wear caused by mismatch of trajectory.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] This embodiment relates to an umbrella rib connection structure, referring to... Figures 1-4 The system includes: umbrella ribs 100 and a pull-back rod 200 hinged to the umbrella ribs 100. The umbrella ribs 100 provide support when the umbrella canopy is unfolded, ensuring the overall stability of the umbrella. The pull-back rod 200 is the transmission component for unfolding or retracting the umbrella ribs 100. The umbrella ribs 100 have a receiving groove 110, and a mounting hole 111 is provided through the center of the receiving groove 110. A hook 210 is located at the end of the pull-back rod 200, connecting the pull-back rod 200 to the umbrella ribs 100 by hooking onto the mounting hole 111. The receiving groove 110 provides space for the hook 210 to move, physically confining the hook 210 within the groove to prevent it from protruding outwards, thus preventing it from scratching the user or damaging the umbrella canopy. This solves the safety and umbrella canopy damage problems associated with protruding hooks 210 in traditional structures. The end of the hook 210 passes through the mounting hole 111 and is accommodated in the receiving groove 110, allowing the hook 210 to move within the receiving groove 110. Therefore, the receiving groove effectively stores and restrains the hook 210, preventing scratches and cuts, avoiding damage to the umbrella surface or injury to the user, and improving the service life and safety of the umbrella rib 100.

[0021] In this embodiment, refer to Figure 2 and Figure 4 The receiving groove 110 is an arc-shaped groove. When the umbrella opens and closes, the hook 210 rotates with the pull rod 200, and its movement path is arc-shaped. The arc-shaped groove can conform to the rotation trajectory of the hook 210, reducing the friction between the hook 210 and the groove wall, making the hook 210 move more smoothly, and avoiding structural jamming or component wear caused by trajectory mismatch. In other embodiments, the receiving groove 110 may also be in other shapes.

[0022] In this embodiment, the height of the receiving groove 110 is at the same level as the end of the hook 210. The end of the hook 210 does not extend beyond the groove plane of the receiving groove 110. Compared with the partial protrusion of the hook 210 in the existing connection structure, it can avoid the hook 210 from contacting the user or the umbrella fabric, further reducing the risk of scratching or snagging, and also achieving a higher degree of flatness.

[0023] In this embodiment, the opening of the receiving groove 110 is rounded. The rounded edges of the groove have a smooth surface, which can further prevent scratching the user's fingers or prevent the user from rubbing against the groove when the umbrella is folded, thus reducing the risk of injury upon contact.

[0024] In this embodiment, the umbrella rib 100 and the receiving groove 110 are integrally formed, which enhances the overall strength of the umbrella rib 100, avoids weak connection points formed by splicing the umbrella rib 100 and the receiving groove 110, and allows for precise control over the position and shape of the receiving groove 110, avoiding dimensional deviations. Specifically, the umbrella rib 100 and the receiving groove 110 are integrally injection molded. In other embodiments, the umbrella rib 100 and the receiving groove 110 may also be integrally stamped or formed by other methods.

[0025] The working principle of this utility model is roughly as follows: When the user operates the umbrella rib 100 to unfold, the hinge point between the pull rod 200 and the umbrella rib 100 rotates upward. During the rotation, the hook 210 slides in the groove along the trajectory of the receiving groove 110. The receiving groove 110 constrains the hook 210 to deflect through the groove wall. As the umbrella rib 100 gradually unfolds, the position of the hook 210 in the receiving groove 110 gradually moves until the umbrella rib 100 is fully opened. When the user operates the umbrella rib 100 to close, the hinge point between the pull rod 200 and the umbrella rib 100 rotates downward. The hook 210 rotates with the pull rod 200 and slides in the opposite direction along the receiving groove 110. The receiving groove 110 continues to constrain the range of motion of the hook 210 until the umbrella rib 100 is fully closed. The hook 210 returns to its initial position in the receiving groove 110, and the pull rod 200 and the umbrella rib 100 fold and fit together, completing the closing action.

[0026] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
