Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, and more specifically to an auxiliary device for seatpost adjustment. Background Technology

[0002] The seatpost is the component in a bicycle frame that connects the saddle to the seat tube. It is mainly used to support the body weight during riding. Conventional round seatposts are highly reliable, inexpensive to manufacture, and highly compatible, and can be adapted to various high-end and low-end bicycle parts.

[0003] The seatpost adjustment directly affects the riding experience and needs to be set comprehensively based on height, riding posture, and frame angle. Too high or too low a seatpost can lead to knee injuries or poor cadence. Therefore, the seatpost height must be adjusted before riding to match the rider's height, riding posture, and frame angle. When using a round seatpost, the seatpost angle also needs to be adjusted according to the saddle, ensuring the length of the saddle is parallel to the direction of the bicycle frame, thus guaranteeing rider comfort.

[0004] However, the seat post height and angle in existing technologies are difficult to accurately position during use, requiring users to make repeated adjustments. This is especially true for folding bikes, where folding requires opening the seat post clamp, lowering the seat post, and then pulling the seat post out again, necessitating readjustment each time, which is inconvenient.

[0005] Therefore, how to provide an auxiliary device for seat post adjustment that allows cyclists to quickly adjust the direction and height of the seat post and saddle before riding is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides an auxiliary device for adjusting the seat post, which aims to solve the problems in the background art mentioned above, so that cyclists can quickly adjust the direction and height of the seat post and saddle before riding.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An auxiliary device for seat post adjustment, comprising:

[0009] The positioning tube is located inside the vertical tube below the bicycle seat and is sleeved on the outer wall of the seat post. The positioning tube is slidably connected to the seat post.

[0010] A positioning groove is provided at the bottom of the positioning tube. Multiple positioning grooves are provided, and the multiple positioning grooves are arranged in pairs along the circumferential direction of the bottom of the positioning tube.

[0011] Positioning pins are provided on the seat tube below the positioning tube. Multiple positioning pins are provided and are arranged one-to-one with the positioning grooves. When the seat tube moves upward, it causes the positioning pins to slide upward into the corresponding positioning grooves.

[0012] Furthermore, an expansion joint is vertically provided on the side wall of the positioning tube, and the expansion joint vertically penetrates the side wall of the positioning tube.

[0013] Furthermore, an extension strip is provided at the top of the positioning tube, and a retaining plate is provided on the outer side wall of the top of the extension strip, with the bottom of the retaining plate being engaged with the top of the vertical tube.

[0014] Furthermore, a fixing ring is provided in the seat tube, and multiple fixing holes are provided on the side wall of the fixing ring, which are respectively set with the positioning pins one by one. The positioning pins are inserted into the fixing holes by passing through the side wall of the seat tube laterally.

[0015] Furthermore, a bottom plug is provided at the bottom of the fixing ring in the seat tube, the bottom plug being threadedly connected to the seat tube and abutting against the bottom of the fixing ring.

[0016] Furthermore, a cover plate is provided at the bottom of the bottom plug, the cover plate is located at the bottom of the seat tube and is fixedly connected to the bottom plug, and a rotating handle is provided at the bottom of the cover plate.

[0017] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an auxiliary device for seat post adjustment. By setting a positioning tube, which is fixedly connected to the outer wall of the vertical tube, the seat post and saddle are adjusted to a reasonable position according to the user's height and riding posture. When the bicycle seat post needs to be stored and used again, the seat post is driven upward so that the positioning pin can quickly slide into the positioning groove. This allows the positioning pin to be quickly engaged in the positioning groove during use. Since the position of the positioning tube and the position of the positioning groove on the positioning tube remain unchanged, the positioning pin can be engaged in the usual position, the height of the seat post is the same as usual, and the direction of the saddle on the seat post is the same as usual. The rider can quickly adjust the direction and height of the seat post and saddle before riding. Attached Figure Description
