Description

Technical Field

[0001] This utility model relates to the field of saddle tube limiting, specifically a saddle tube bundle that prevents jamming and tilting. Background Technology

[0002] The seat tube is a key component of a bicycle frame, typically located slightly rear-middle of the frame. It's a tubular structure, named for its resemblance to a saddle's support tube. It connects to the top tube at the top and to the bottom bracket (or bottom bracket) at the bottom, serving as a crucial stress point in the frame structure that bears the rider's weight and pedaling force. The seat tube is height-adjustable, with a telescopic design to accommodate riders of different heights, ensuring comfortable riding posture and stable handling. Its materials are often aluminum alloy or carbon fiber, balancing strength and lightweight design. The proper design and installation of the seat tube directly impacts the riding experience and is a vital aspect of optimizing bicycle performance.

[0003] Existing saddle tube harnesses have certain defects in their installation and fixation. After prolonged use, the saddle tube harness is prone to loosening due to frequent stress and material fatigue, affecting riding safety and comfort. To solve this problem, the common practice is to remove the middle section of the saddle tube harness and only install corresponding grooves and protrusions at both ends for fixation. However, this improvement also has drawbacks. The stress is concentrated at both ends, which can easily lead to accelerated local wear over long-term use. Moreover, the grooves and protrusions require high precision in their fit; even slight deviations in manufacturing will not only fail to provide effective fixation but will also further accelerate the loosening process.

[0018] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a saddle tube bundle for preventing jamming and tilting, including a saddle tube bundle 1, the saddle tube bundle 1 including a middle section locking block 12, an upper locking block 11 is inserted at the top of the middle section locking block 12, and a lower locking block 13 is inserted at the bottom of the middle section locking block 12.

[0020] The saddle tube bundle 1 uses three sets of fixing structures (upper, middle, and lower) to classify and fix the saddle tube, ensuring stability. The upper and lower sets of locking blocks can be adjusted in lateral angle to adapt to different scenarios according to actual needs. To adjust the fixing tightness, simply tighten the two sets of built-in bolts. This easy-to-adjust design is not only convenient to operate, but also avoids interference between components, effectively preventing the saddle tube from warping and providing reliable protection during use.

[0021] The upper locking block 11 includes a first wire locking plate 111 and a second wire locking plate 112. The bottom end of the first wire locking plate 111 is provided with a first horizontal groove, and the top end of the second wire locking plate 112 is provided with a second horizontal groove corresponding to the first horizontal groove. The top end of the first wire locking plate 111 is provided with a through first round hole, and the top end of the second wire locking plate 112 is provided with a through first square hole.

[0022] The middle section locking block 12 includes an adjustable locking block 121. The top of the adjustable locking block 121 has a through square opening, and a longitudinal connecting rod 122 is inserted into the square opening.

[0023] The lower locking block 13 includes a third locking plate 131 and a fourth locking plate 132. The top of the third locking plate 131 is provided with a third horizontal slot, and the bottom of the fourth locking plate 132 is provided with a fourth horizontal slot corresponding to the third horizontal slot. The top of the third locking plate 131 is provided with a through second round hole, and the top of the fourth locking plate 132 is provided with a through second square hole.

[0024] Both the first wire-locking plate 111 and the third wire-locking plate 131 are provided with locking blocks 14, and both the second wire-locking plate 112 and the adjustable locking block 121, as well as the fourth wire-locking plate 132 and the adjustable locking block 121, are provided with matching locking slots 15, and the locking blocks 14 and the locking slots 15 are fastened together.

[0025] The locking block 14 on the first cable clamping plate 111 is located on the opposite side of the first and second transverse slots. The locking block 14 on the third cable clamping plate 131 is located on the opposite side of the third and fourth transverse slots. The cooperation between the locking blocks and the slots at both ends effectively prevents the saddle tube from tilting upwards.

[0026] The top and bottom ends of the longitudinal connecting rod 122 are fixedly connected with threaded joints. The two ends of the longitudinal connecting rod 122 pass through the upper locking block 11 and the lower locking block 13 respectively. The two sets of threaded joints are respectively threadedly connected to the first adjusting nut 113 and the second adjusting nut 133.

[0027] During assembly, firstly, slide the adjustable locking block 121 into the middle of the longitudinal connecting rod 122. Then, slide the second wire-locking plate 112 and the fourth wire-locking plate 132 into the top and bottom of the longitudinal connecting rod 122, respectively. Since the longitudinal connecting rod 122 has a square cross-section, the second wire-locking plate 112 and the fourth wire-locking plate 132 can be installed in four directions. Next, slide the first wire-locking plate 111 and the third wire-locking plate 131 into the top and bottom of the longitudinal connecting rod 122, respectively. During installation, ensure that the first transverse groove is aligned with the second transverse groove, and the third transverse groove is aligned with the fourth transverse groove. This also ensures that the locking block and the slots are on the same straight line, achieving a tight engagement between the locking block and the slots. The pipeline can then be installed in the first transverse groove and the second transverse groove, respectively. After installation, tighten the first adjusting nut 113 and the second adjusting nut 133 inside the transverse slot, the third transverse slot, the fourth transverse slot, and the adjustable locking block 121. The first adjusting nut 113 presses down on the first wire clamping plate 111, causing the first wire clamping plate 111 to clamp the wire harness downwards. The second adjusting nut 133 presses up on the third wire clamping plate 131, causing the third wire clamping plate 131 to clamp the wire harness upwards. After continuing to tighten the two sets of nuts, the second wire clamping plate 112 will slide downwards and the fourth wire clamping plate 132 will slide upwards. At this time, the adjustable locking block 121 will be pressed inwards to clamp the wire harness installed inside. The transverse slot design can effectively limit and fix the wire harness, reduce wear caused by sliding, and extend the overall service life.

[0028] The bottom of the second wire-locking plate 112 and the top of the fourth wire-locking plate 132 are provided with several anti-slip grooves 16 arranged in a circle. These two sets of anti-slip grooves 16 correspond to the top and bottom of the adjustable locking block 121, respectively.

[0029] The anti-slip groove 16 design increases friction, reduces the possibility of sliding between the two sets of cable clamps and the adjustable clamp 121, and improves the overall stability after installation.
