Description

Technical Field

[0001] This utility model relates to the field of bicycle seatposts, and in particular to aluminum alloy bicycle seatposts. Background Technology

[0002] Bicycles, also known as pedal bikes or bicycles, are usually small two-wheeled land vehicles that can be used as an environmentally friendly means of transportation for getting around. More and more people are using bicycles as fitness equipment for cycling exercise and cycling tours. Bicycles are also a competitive sport, including road cycling races, mountain biking races, track cycling races, and stunt cycling races.

[0003] A search revealed Chinese Patent Publication (Announcement) No. CN201923245U, which discloses an anti-theft quick-release seat post structure, including a bicycle seat post, a quick-release handle on the seat post, a notch on the quick-release handle, and a padlock in the notch. When riding, the bicycle seat is adjusted to a suitable height using the quick-release handle, and then the padlock is locked to achieve the purpose of anti-theft.

[0004] However, the existing method of adjusting the saddle height via a quick-release lever and then locking the padlock has drawbacks: the seatpost tends to slip during riding, requiring the application of anti-slip fluid to the clamping area, which is cumbersome and lacks safety. A lowered seatpost also leads to riding discomfort. Therefore, this invention proposes an improved aluminum alloy bicycle seatpost. Utility Model Content

[0005] Therefore, to address the technical problem of slippage during riding and the need to apply anti-slip liquid to the clamping area, an aluminum alloy bicycle seatpost is provided, comprising: a frame, a mounting tube on the frame, a slot inside the mounting tube, a tube clamp fitted on the circumferential side of the top of the mounting tube, a seatpost body inside the slot, a plurality of limiting grooves symmetrically formed on the circumferential side of the seatpost body, a movable groove symmetrically formed on the inner wall of the mounting tube, a retaining groove symmetrically formed on the inner wall of the tube clamp, a rotating screw inserted through one side of the inner wall of the retaining groove, one end of the rotating screw being disposed in the movable groove, a rotating shaft fitted on the circumferential side of one end of the rotating screw, a retaining block provided on one side of the rotating shaft, and a threaded hole formed on one side of the tube clamp. A bolt is threaded into the threaded hole. A sleeve is provided on one side of the pipe clamp at the left end of the bolt. The bolt passes through the threaded hole and the sleeve and is threadedly connected to the threaded hole and the sleeve. A circular groove is opened in the body of the seat tube. A nut is threadedly connected to the bottom end of the circular groove. A positioning post is provided in the circular groove. A spring is provided in the circular groove. A sliding post is provided in the circular groove. A connecting tube is provided on the upper surface of the sliding post. A mounting seat is provided at the upper end of the connecting tube. The positioning post is set on the nut. A locking post that mates with the lower end of the spring is provided at the top of the positioning post. A locking post that mates with the upper end of the spring is provided at the bottom end of the sliding post. The lower end of the spring is sleeved on the locking post at the top of the positioning post. The upper end of the spring is sleeved on the locking post at the bottom end of the sliding post.

[0006] In one embodiment, one side of the inner wall of the slot is threadedly engaged with the rotating screw, the slot communicates with the movable groove, the shape and size of the movable groove are adapted to the limiting groove, the movable groove communicates with the limiting groove, the shape and size of the locking block are adapted to the limiting groove, and the locking block is engaged with the limiting groove.

[0007] In one embodiment, the inner ring of the rotating shaft is fixedly connected to one side of the rotating screw, one side of the outer ring of the rotating shaft is fixedly connected to one side of the locking block, a plurality of scale grooves are symmetrically arranged on the side of the seat tube body, the scale grooves are located above the limiting grooves, the mounting tube is welded to the frame, and a knob is provided at one end of the bolt.

[0008] During operation, the aluminum alloy bicycle seatpost is inserted into the slot, aligned with the top of the mounting tube via the graduated groove. Then, the rotating screw is turned, engaging with the inner ring of the shaft. This pushes the locking block into the limiting groove on the side of the seatpost. Turning the knob then rotates the bolt, clamping the tube to prevent slippage during riding. Anti-slip fluid is applied to the clamping area. During riding, if the bicycle bumps, the connecting tube compresses the spring via a sliding column. The spring absorbs the force generated by the bumps, reducing the impact of the ride.
