Description

Technical Field

[0001] This utility model relates to the field of tube-head technology, specifically a concealed tube-head folding mechanism. Background Technology

[0002] The head tube is a key component integrated into the folding structure. It is typically used to connect and support the front-end components (such as handlebars and forks), and plays a guiding, positioning, and structural stability role during folding. Through clever design, the head tube not only enables devices (such as folding bicycles, mobility scooters, or portable electronic device cables) to fold efficiently and save space, but also ensures a firm connection and smooth operation when unfolded, thus balancing portability, durability, and user experience.

[0003] Existing end caps present significant operational inconveniences during practical use, particularly in handheld handling and installation. Lacking a dedicated grip structure or auxiliary design, users often need to support or hold the entire end cap with their hand for movement and positioning. Furthermore, the size of the end cap varies considerably depending on the application – when encountering large or heavy end caps, not only is it difficult to maintain a stable grip with one hand, but instability can also lead to slippage or installation deviations, significantly increasing operational difficulty and physical strain. Utility Model Content

[0004] The purpose of this invention is to provide a concealed folding mechanism for a tube with a head, thereby solving the problem mentioned in the background art that existing tubes with heads generally lack a dedicated grip structure, requiring users to hold them with their entire hand during handling and installation, which is inconvenient. This is especially true for large and heavy tubes, which are difficult to hold stably, are prone to slipping or shifting, and increase the difficulty and burden of operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concealed folding mechanism for a tube with a head, comprising a connecting block installed at the bottom of the tube body, a folding assembly installed in the inner cavity of the connecting block, the folding assembly including a storage groove, a rotating rod rotatably connected to the inner cavity of the storage groove, a mounting plate fixedly connected to the outer surface of the rotating rod, a fixing seat fixedly connected to the rear side of the mounting plate, and a pull plate installed on the rear side of the fixing seat, for carrying the tube body with the head, thus achieving portability.

[0006] Furthermore, a groove is provided on the rear side of the fixing seat, and the inner cavity of the groove is fixedly connected to one side of the pull plate.

[0007] Furthermore, a connecting plate is fixedly connected to one side of the pull plate, and the connecting plate and the pull plate cooperate with each other.

[0008] Furthermore, a positioning plate is fixedly connected to the top of the inner cavity of the storage slot, and a guide plate is fixedly connected to the rear side of the mounting plate, with the positioning plate and the guide plate in contact.

[0009] Furthermore, a concave surface is provided on one side of the connecting block.

[0010] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0011] This invention, by incorporating a folding component, significantly improves the convenience of carrying and handling the head tube. Users can quickly unfold the folding mechanism when installing the head tube; after installation, the handle can be folded and retracted to fit snugly against or embed into the head tube body, achieving a compact and integrated structure. This design saves space, avoids interference from protruding parts, enhances the overall appearance and portability, and effectively prevents damage to the handle during transportation or storage due to shaking or collisions, thus balancing functionality, safety, and aesthetics.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: A concealed folding mechanism with a head tube, such as Figures 1-6 As shown, a connecting block 11 is installed at the bottom of the tube body 1 with a head. A folding component 2 is installed in the inner cavity of the connecting block 11. The folding component 2 includes a storage groove 21, which is opened on the front side of the inner cavity of the connecting block 11 to facilitate the installation of the folding component 2. A rotating rod 22 is rotatably connected to the inner cavity of the storage groove 21. The rotating rod 22 is rotatably connected to the inner cavity of the storage groove 21 through a damping bearing.

[0023] like Figures 2-6 As shown, a mounting plate 23 is fixedly connected to the outer surface of the rotating rod 22, and a fixing seat 24 is fixedly connected to the rear side of the mounting plate 23. A pull plate 26 is installed on the rear side of the fixing seat 24. The pull plate 26 is easy for the user to pull and is used to carry the tube body 1 with the head, thus achieving the purpose of portability. A groove 27 is provided on the rear side of the fixing seat 24, and the inner cavity of the groove 27 is fixedly connected to one side of the pull plate 26.

[0024] like Figures 1-6 As shown, a connecting plate 25 is fixedly connected to one side of the pull plate 26, and the connecting plate 25 and the pull plate 26 cooperate with each other to form a concave surface, which further increases the contact area with the user's palm, making it easier for the user to pull the pull plate 26 to operate the entire folding assembly 2. A positioning plate 28 is fixedly connected to the top of the inner cavity of the storage slot 21, and a guide plate 29 is fixedly connected to the rear side of the mounting plate 23, and the positioning plate 28 and the guide plate 29 are in contact.

[0025] Specifically, when the user manually pulls the connecting plate 25 forward, the connecting plate 25 causes the mounting plate 23 to rotate around the rotating rod 22 as the rotation center, thereby flipping the entire mounting plate 23, making it easy for the user to pull the mounting plate 23 to carry the head tube body 1; conversely, the rotating rod 22 causes the mounting plate 23 to swing back to its original position. During the resetting process, the guide plate 29 and the positioning plate 28 cooperate with each other to effectively prevent the mounting plate 23 from shifting position.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
