Description

Technical Field

[0001] This utility model relates to the field of tube clamps, specifically to a novel tube clamp for bicycle saddle tubes. Background Technology

[0002] The primary function of a bicycle seatpost is to support the rider's weight and provide a mounting position for the saddle. Bicycle seatposts are typically made of metals such as aluminum alloy or carbon fiber, offering high strength and durability. They are usually tubular, connecting at one end to the seat tube of the bicycle frame and at the other end to the saddle. The seatpost usually has an internal liner to reduce pressure on the saddle. However, an improper seatpost height can lead to falls or injuries during riding, making quick-release seatpost clamps essential for rapid adjustment. Utility Model Content

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0018] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A novel bicycle saddle post clamp includes a clamp assembly comprising a first anti-theft locking screw 1, a second anti-theft locking screw 2, a first cylindrical convex pin 3, a second cylindrical convex pin 4, a spiral 7, a handlebar 8, a clamp ring 9, a handlebar limiting post 14, and a positioning clip 15. The first cylindrical convex pin 3, the second cylindrical convex pin 4, the spiral 7, and the handlebar 8 are respectively mounted on the clamp ring 9 via the first anti-theft locking screw 1 and the second anti-theft locking screw 2. The spiral 7 has a positioning protrusion 5 on its side. The end of the clamp ring 9 is an end block with an anti-rotation groove 6 matching the positioning protrusion 5. The spiral 7 has a groove 10 on its side. The end of the handlebar 8 has a pin positioning hole 11. The clamping ring 9 has screw holes 12 on its side, and the end block has screw through holes 13. The handle limiting post 14 is fixedly installed on the side of the handle 8, and the positioning card 15 is fixedly installed on the inner side of the clamping ring 9. The guide assembly is installed on the side of the clamping ring 9 by screws. The guide assembly includes a mounting block 16, a connecting rod 17, a connecting ring 18, a limiting block 19, a mounting ring 20, a fixing block 21, and a guide rod 22. The connecting rod 17 is fixedly connected between the mounting block 16 and the connecting ring 18. The limiting block 19 is fixedly installed at the end of the connecting ring 18. The fixing block 21 is fixedly connected to the side of the mounting ring 20. The guide rod 22 is fixedly connected to the fixing block 21.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first anti-theft locking screw 1 is screwed into the interior of the second anti-theft locking screw 2, and the interior of the second anti-theft locking screw 2 is provided with a threaded groove that matches the first anti-theft locking screw 1. Two of each of the first cylindrical convex pin 3 and the second cylindrical convex pin 4 are provided. The ends of the first cylindrical convex pin 3 and the second cylindrical convex pin 4 pass through the pin positioning hole 11 and extend into the groove 10. The pin positioning hole 11 prevents the first cylindrical convex pin 3 and the second cylindrical convex pin 4 from falling out when the handle 8 is lifted upwards or pressed downwards.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning protrusion 5 and the spiral 7 are integrally formed. The positioning protrusion 5 is located within the anti-rotation groove 6. Through the cooperation of the positioning protrusion 5 and the anti-rotation groove 6, when the handle 8 is lifted upwards or pressed downwards, the first cylindrical convex pin 3 and the second cylindrical convex pin 4 rotate with the handle 8, while the spiral 7 and the clamping ring 9 remain fixed. There are two spirals 7, and the spirals 7 are in contact with the end block.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, there is a gap between the end blocks, and the handle limiting post 14 is located below the end blocks, so that after the handle 8 is pressed down to lock in place, the handle limiting post 14 can abut against the clamping ring 9 to prevent over-locking. The handle 8 has a U-shaped structure, and both the end of the handle 8 and the side of the screw 7 have openings to facilitate the passage of the first anti-theft locking screw 1 and the second anti-theft locking screw 2.

[0023] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a screw threaded through the end of the mounting ring 20, a nut screwed onto the outside of the screw, and a soft rubber pad with anti-slip protrusions adhered to the side of the mounting ring 20. The mounting block 16 has a threaded hole on its side that matches the screw. The guide rod 22 slides in contact with the limiting block 19. The surface of the limiting block 19 has a sliding through hole corresponding to the guide rod 22, and the end of the guide rod 22 passes through the sliding through hole.

[0024] In use: First, screw the end of the screw to the seat tube of the bicycle frame to install the clamp 9. Then, use the screw and nut to install the mounting ring 20 on the saddle tube near the saddle seat. The soft rubber pad is placed between the saddle tube and the mounting ring 20, and the nut is placed on the end of the mounting ring 20. Then, lift the handle 8 upwards. When the handle 8 is lifted upwards, the first cylindrical convex pin 3 and the second cylindrical convex pin 4 rotate simultaneously and slide within the groove 10 of the spiral 7. The spiral 7 rotates from the shallow concave part to the deep concave part, causing the spiral 7 to move outwards, which will loosen the clamp 9 and enlarge its inner diameter. Then, insert the saddle tube into the seat tube of the bicycle frame and move the saddle tube up and down. The guide rod 22 will slide along the sliding through hole of the limit block 19. This design prevents the saddle from tilting during saddle tube height adjustment, ensuring riding comfort and safety. Once the saddle tube is adjusted to the appropriate height, pressing down the handlebar 8 causes the first cylindrical convex pin 3 and the second cylindrical convex pin 4 to rotate simultaneously, sliding within the groove 10 of the spiral 7. The spiral 7 moves inward from a deep groove to a shallow one, clamping the clamping ring 9 and reducing its inner diameter. This clamps and secures the bicycle frame seat tube and the saddle tube inserted within the seat tube, preventing saddle tube displacement. This product allows for quick saddle tube height adjustment simply by manipulating the handlebar, providing a convenient and rapid adjustment for the user.

Furthermore, the scope of this invention is not limited to the specific combinations of the above-described technical features, but also includes other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
