Description

Technical Field

[0001] This utility model belongs to the technical field of seat tube bundle load structure, and in particular relates to a hidden hollow seat tube bundle load structure for high-performance carbon fiber frames. Background Technology

[0002] The seatpost harness is a device that is fixed to the bottom tube of a bicycle to secure the saddle. Currently, most seatpost harnesses commonly used on bicycles are fixed to the bottom tube with bolts and lock nuts. When it is necessary to replace the seatpost harness, the disassembly process is relatively cumbersome, which increases the user's workload, reduces the user's work efficiency, and causes great inconvenience to the user.

[0003] Chinese patent application CN207843126U discloses a concealed bicycle seatpost assembly, including a center tube, a base at the top of the center tube, and a tube body inside the center tube. The top of the tube body communicates with the base. Housings are fixedly connected to both sides of the center tube. Sliding rods are fixedly connected to the top and bottom of the inner and outer sides of the housings. Sliding sleeves are fitted onto the surface of the sliding rods, and baffles are fixedly connected to opposite sides of the two sliding sleeves. This invention solves the problem of inconvenient disassembly of concealed bicycle seatpost assemblies by using the center tube, housing, pull plate, base, pull rod, tube body, first through hole, positioning rod, positioning groove, return spring, baffle, second through hole, sliding sleeve, sliding rod, and third through hole in combination. This concealed bicycle seatpost assembly has the advantage of easy disassembly, reducing the user's workload, improving user efficiency, and greatly facilitating disassembly. It is worthy of promotion.

[0004] While this patent achieves the function of concealed constraint, its structure is complex, and because it uses a spring as a power source, the spring will deform and lose its elasticity after prolonged use, leading to a loss of constraint function. To address these issues, we provide a high-performance carbon fiber frame concealed hollow seatpost load structure. Utility Model Content

[0005] The purpose of this utility model is to provide a high-performance carbon fiber frame with a hidden hollow seatpost harness structure. Through the cooperation of the frame and the restraint components, it solves the problems of the complex structure of the existing seatpost harness structure, which leads to cumbersome maintenance in the later stage, and the failure of the spring as a power source after long-term use.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a concealed hollow seat tube bundle structure for a high-performance carbon fiber bicycle frame, comprising a frame, a constraint assembly movably connected to the inner cavity of the frame, a groove for placing the constraint assembly on the top of the frame, a mounting groove on the top of one side of the groove, a mounting hole and a first through hole on the top of the mounting groove, the constraint assembly comprising a constraint tube inserted into the inner cavity of the groove and a mounting block sleeved in the inner cavity of the mounting groove, a pressing block slidably connected to the inner cavity of the mounting block, one side of the pressing block being in close contact with the surface of the constraint tube, and a pull handle fixedly connected to one side of the top of the pressing block.

[0008] The present invention is further configured such that the top of the mounting block has a threaded hole and a second through hole, the threaded hole being aligned with the mounting hole, and the second through hole being aligned with the first through hole. The end of the pull handle away from the compression block passes through the inner cavities of the second through hole and the first through hole in sequence and extends to the top of the frame. The threaded hole is aligned with the mounting hole of the frame, providing a precise threaded fit foundation for the installation of the external screw, ensuring that the screw can be stably inserted and apply pressure to the compression block, and avoiding the screw failing to effectively contact the compression block due to hole position deviation. At the same time, the alignment of the second through hole with the first through hole ensures that the pull handle can smoothly pass through the mounting block and extend to the top of the frame, preventing the pull handle from getting stuck or worn during pulling due to hole misalignment, improving the fit accuracy between the mounting block and the frame and the pull handle, and providing structural protection for the smoothness of subsequent constraint operations.

[0009] The present invention is further configured such that the inner cavity of the threaded hole is threadedly connected to the outer screw, the bottom of the outer screw is in close contact with the top of the extrusion block, and the top of the outer screw passes through the inner cavity of the mounting hole and extends to the top of the frame. Through the threaded connection between the outer screw and the threaded hole, the user can flexibly adjust the pressure of its bottom on the extrusion block by turning the screw, thereby precisely controlling the degree of extrusion of the extrusion block on the constraint tube.

[0010] The present invention is further configured such that the inner cavity of the extrusion block is provided with a sliding groove, and a sliding rod is slidably connected to the inner cavity of the sliding groove. The two ends of the sliding rod are fixedly connected to the inner wall of the mounting block. The cooperation between the sliding groove and the sliding rod defines a clear sliding path for the extrusion block, preventing the extrusion block from shifting, tilting or getting stuck when subjected to pressure or being pulled, and ensuring that the extrusion block always slides smoothly along the preset direction.

[0011] The present invention is further configured such that the extrusion block is wedge-shaped, and the wedge structure can efficiently convert the axial pressure of the external screw into radial extrusion force on the constraint tube, thereby improving the extrusion efficiency without the need for additional power components.

[0012] The present invention is further configured such that a socket is fixedly connected to one side of the top of the extrusion block, and the handle is glued to the inner cavity of the socket by adhesive. The socket provides a special mounting carrier for the handle, making the installation position of the handle more precise and the fixation more stable.

[0013] The present invention is further configured such that deformation grooves are provided on both the front and back sides of the constraint tube. The deformation grooves allow the constraint tube to undergo moderate elastic deformation when subjected to radial pressure from the compression block, thereby better conforming to the outer wall of the seat tube, increasing the contact area and friction between the two, and improving the tube bundle stability of the seat tube.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model, through the cooperation of constraint components, grooves, mounting slots, handles and screws, allows users to quickly release and switch the constraint of the compression block on the constraint tube without disassembling multiple scattered parts. Users can simply pull the handle to adjust the position of the compression block and turn the screw to control the pressure. This greatly simplifies the disassembly and adjustment process of the seat tube bundle, reduces operation time and labor intensity, and provides great convenience for subsequent maintenance and replacement of seat tube related components, significantly improving the efficiency of use.

[0016] 2. This utility model effectively avoids the core defects of complex structure and easy failure of spring. This structure uses the mechanical cooperation of extrusion block and external screw to replace spring, which makes the structure simpler and reduces the use of easily worn parts. At the same time, the axial pressure adjustment of the screw is stable and reliable, and will not have the problem of elasticity decay similar to that of spring due to long-term use. It can continuously provide stable pressure to the extrusion block, ensuring the effective extrusion of the extrusion block on the constraint tube, maintaining the stability and durability of the seat tube binding function in the long term, extending the service life of the overall structure and improving the safety of use.

[0023] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-4 This utility model is a high-performance carbon fiber frame with a hidden hollow seat tube bundle structure, including a frame 1. A constraint component 2 is movably connected to the inner cavity of the frame 1. A groove 3 is provided on the top of the frame 1 for placing the constraint component 2. A mounting groove 4 is provided on the top of one side of the inner cavity of the groove 3. A mounting hole 5 and a first through hole 6 are respectively provided on the top of the inner cavity of the mounting groove 4. The constraint component 2 includes a constraint tube 21 inserted into the inner cavity of the groove 3 and a mounting block 22 sleeved in the inner cavity of the mounting groove 4. A pressing block 23 is slidably connected to the inner cavity of the mounting block 22. One side of the pressing block 23 is in close contact with the surface of the constraint tube 21. A pull handle 24 is fixedly connected to one side of the top of the pressing block 23.

[0025] Specifically: the depth of the groove 3 is adapted to the installation length of the seat tube to ensure that the seat tube can be inserted completely; the mounting groove 4 matches the shape of the mounting block 22; the mounting hole 5 is a smooth round hole for external components to be inserted to adjust the pressure; the first through hole 6 is a smooth hole with a diameter adapted to the outer diameter of the handle 24; the two are spaced horizontally at the top of the mounting groove 4 to avoid interference between subsequent components during operation; the constraint tube 21 is a hollow tubular structure with an inner diameter adapted to the outer diameter of the seat tube, used to fit and support the seat tube; the outer wall of the constraint tube 21 fits against the inner wall of the groove 3 to ensure stability.

[0026] The top of the mounting block 22 has a threaded hole 25 and a second through hole. The threaded hole 25 is aligned with the mounting hole 5, and the second through hole is aligned with the first through hole 6. The end of the handle 24 away from the compression block 23 passes through the inner cavity of the second through hole and the first through hole 6 and extends to the top of the frame 1. The threaded hole 25 is aligned with the mounting hole 5 of the frame 1, providing a precise threaded fit foundation for the installation of the external screw, ensuring that the screw can be stably inserted and apply pressure to the compression block 23, and avoiding the screw from failing to effectively contact the compression block 23 due to hole position deviation. At the same time, the alignment of the second through hole with the first through hole 6 ensures that the handle 24 can smoothly pass through the mounting block 22 and extend to the top of the frame 1, preventing the handle 24 from getting stuck or worn during the pulling process due to hole misalignment, improving the fit accuracy between the mounting block 22, the frame 1, and the handle 24, and providing structural protection for the smoothness of subsequent constraint operations.

[0027] The inner cavity of the threaded hole 25 is threadedly connected to the outer screw. The bottom of the outer screw is in close contact with the top of the extrusion block 23. The top of the outer screw passes through the inner cavity of the mounting hole 5 and extends to the top of the frame 1. Through the threaded connection between the outer screw and the threaded hole 25, the user can flexibly adjust the pressure of its bottom on the extrusion block 23 by turning the screw, thereby precisely controlling the degree of extrusion of the extrusion block 23 on the constraint tube 21.

[0028] The inner cavity of the extrusion block 23 is provided with a groove 26, and a slide rod 27 is slidably connected to the inner cavity of the groove 26. The two ends of the slide rod 27 are fixedly connected to the inner wall of the mounting block 22. The cooperation between the groove 26 and the slide rod 27 defines a clear sliding path for the extrusion block 23, preventing the extrusion block 23 from shifting, tilting or jamming when subjected to pressure or being pulled, and ensuring that the extrusion block 23 always slides smoothly in the preset direction.

[0029] The extrusion block 23 has a wedge-shaped design. The wedge structure can efficiently convert the axial pressure of the external screw into radial extrusion force on the constraint tube 21, thereby improving extrusion efficiency without the need for additional power components.

[0030] A socket 28 is fixedly connected to one side of the top of the extrusion block 23. The handle 24 is glued to the inner cavity of the socket 28 with adhesive. The socket 28 provides a special mounting carrier for the handle 24, making the installation position of the handle 24 more precise and the fixation more stable.

[0031] Deformation grooves 29 are provided on both the front and back sides of the constraint tube 21. The deformation grooves 29 allow the constraint tube 21 to undergo moderate elastic deformation when subjected to radial pressure from the compression block 23, thereby better fitting the outer wall of the seat tube, increasing the contact area and friction between the two, and improving the tube bundle stability of the seat tube.

[0032] The working principle of this utility model is as follows: The mounting block 22 is fitted into the mounting groove 4 on one side of the inner cavity of the groove 3, and the pull handle 24 at the top of the pressing block 23 passes through the second through hole of the mounting block 22 and the first through hole 6 of the frame 1 in sequence, extending to the top of the frame 1. Then, the constraint tube 21 is inserted into the inner cavity of the groove 3 at the top of the frame 1, so that the outer wall of the constraint tube 21 fits against the inner wall of the groove 3; at the same time, it is ensured that the pressing block 23 side of the inner cavity of the mounting block 22 is in contact with the surface of the constraint tube 21. When it is necessary to constrain the seat tube, the external screw passes through the mounting hole 5 of the frame 1 and is threadedly connected to the threaded hole 25 of the mounting block 22. The external screw is screwed so that its bottom presses the pressing block 23 downward. The pressing block 23 moves along the sliding groove 2 in the inner cavity of the mounting block 22. The sliding path of the 6th slides with the slide bar 27. Because the extrusion block 23 is wedge-shaped, it generates radial extrusion force on the constraint tube 21 during the sliding process. After being subjected to extrusion force, the constraint tube 21 undergoes moderate deformation through the deformation grooves 29 on the front and back sides, tightly fitting the outer wall of the seat tube inserted therein, thereby fixing the seat tube bundle. When it is necessary to disassemble or adjust the seat tube, the external screw is turned in the opposite direction to separate its bottom from the extrusion block 23, reducing the pressure on the extrusion block 23. Then, the handle 24 on the top of the frame 1 is pulled to drive the extrusion block 23 to slide in the opposite direction along the slide bar 27, releasing the extrusion force on the constraint tube 21. The constraint tube 21 returns to its original shape through the deformation groove 29, and the seat tube can be taken out from the constraint tube 21 or its position adjusted to complete the disassembly or adjustment operation.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
