Technical Field

[0001] The utility model belongs to the technical field of bicycle saddle installation, and in particular relates to a saddle installation structure for a bicycle. Background Art

[0002] The design of a bicycle saddle mounting structure involves multiple aspects such as rider comfort, safety and convenience. The existing bicycle saddle mounting structure usually includes a saddle tube and a locking sleeve for fixing the saddle tube to the frame tube. However, there is a problem with some existing bicycle saddle mounting structures, that is, the locking sleeve is easy to fall off the frame tube when adjusting the connection. This problem may be caused by a variety of reasons, such as unreasonable design of the locking mechanism, weak structure of the locking sleeve, etc. The falling of the locking sleeve will not only increase the difficulty and time of installation, but also may affect the safety and comfort of riding. Therefore, the existing bicycle saddle mounting structure needs to be further improved and innovated to improve the convenience of installation and the safety of riding. Utility Model Content

[0012] 1. The existing bicycle saddle installation structure has the problem that the locking sleeve is easy to fall off the frame tube when the two connecting tubes are locked and adjusted, which makes the one-hand installation inconvenient, time-consuming and laborious. The frame tube elastic clamping sleeve is inserted into the frame, so as to facilitate the positioning of the saddle frame locking sleeve on the frame tube, and then the saddle connecting tube is inserted into the frame tube. At this time, the saddle frame locking sleeve clamps the two tubes, and the two screw clamps are locked by the locking screw as the rotating handle rotates, so as to achieve the clamping and fixing connection between the saddle tube and the frame tube. The existing bicycle saddle installation structure solves the problem that the locking sleeve is easy to fall off the frame tube when the two connecting tubes are locked and adjusted, which makes the one-hand installation inconvenient, time-consuming and laborious.
