Description

Technical Field

[0001] The utility model relates to the technical field of bicycle structures, in particular to a bicycle seat tube locking structure. Background Art

[0002] At present, with the increasing awareness of health and green living among people and the continuous maturity and innovation of bicycle technology, bicycles have become the simplest, most practical and most widely used means of transportation in the world.

[0003] In order to meet the requirements of people of different heights for bicycles, meet the different riding postures of riders, and improve the comfort of riders, the seat height of existing bicycles is usually adjustable up and down. Existing seat tubes are usually locked and fixed with bolts. With this design, when bumps occur during riding, the bolts are easy to loosen or fall off, thereby affecting the stability of the seat fixation. When adjusting the bolts, they need to be twisted twice with a tool, which not only requires a certain amount of force but also the process is cumbersome.

[0004] Therefore, how to provide a bicycle seat tube locking structure that can quickly prevent loosening has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by the utility model is how to provide a bicycle seat tube locking structure which can quickly prevent loosening.

[0006] To achieve the above-mentioned purpose, the utility model provides a bicycle seat tube locking structure, including: a bicycle frame, a connecting mechanism is arranged on the bicycle frame for connecting the bicycle seat, a locking mechanism is arranged at the connection between the bicycle seat and the connecting mechanism for use with the bicycle seat, the locking mechanism includes a limiting hole, a locking piece and an elastic piece, a plurality of limiting holes are arranged, the locking piece is arranged on the outside of the limiting hole, one end of the locking piece is inserted into the limiting hole, and the elastic piece is arranged on the locking piece to form a fast and stable locking structure for the bicycle seat.

[0007] The bicycle frame adopts the existing structure on the market, and the connecting mechanism is used to install the bicycle seat on the bicycle frame in an adjustable manner. This technical means is common knowledge in the field, so it is not repeated here. The elastic member limits the lateral movement of the locking member, so that the locking member can be quickly and stably inserted into the limiting hole, ensuring the stability of locking the bicycle seat.

[0008] Preferably, the connecting mechanism comprises a mounting sleeve and a seat tube.

[0009] The mounting sleeve and the seat tube adopt the existing structure on the market, so they will not be described in detail.

[0010] Preferably, the mounting sleeve is welded to the bicycle frame and is designed to be inclined.

[0011] The welding design ensures the stability of the connection between the mounting sleeve and the bicycle frame, and the inclined design forms a certain angle. This design has a certain labor-saving effect.

[0012] Preferably, the seat tube is movably arranged inside the mounting sleeve, and the top of the seat tube is threadedly connected to a bicycle seat.

[0013] The movable design allows users to adjust the height of the bicycle seat according to actual needs. The threaded connection not only ensures the stability of the bicycle seat installation, but also facilitates the later replacement and maintenance of the bicycle seat.

[0014] Preferably, the limiting holes are preset on the seat tube at equal longitudinal intervals.

[0015] The inside of the limit hole is coated with a resistance-enhancing material to ensure the stability of the connection between the limit hole and the locking piece.

[0016] Preferably, the cross-section of the locking piece is a "T"-shaped structure, and the radius of the locking piece corresponds to the radius of the limiting hole.

[0017] The locking member and the limiting hole having corresponding radii further ensure the stability of the connection between the locking member and the limiting hole.

[0018] Preferably, the locking member and the mounting sleeve have opposite magnetic poles.

[0019] This design allows the locking piece to fit tightly against the inner wall of the mounting sleeve.

[0020] Preferably, two elastic members are provided on the locking member, and the other ends of the two elastic members are connected to the outer wall of the mounting sleeve, and the two elastic members are both reset springs.

[0021] The design of the elastic member limits the lateral movement of the locking member and prevents the locking member from falling off.

[0022] The beneficial effects of the utility model are:

[0023] When the utility model is in use, the locking piece is designed with an elastic piece to avoid the phenomenon of the elastic piece falling off, and the design of controlling the locking piece by the elastic piece can improve the fixing efficiency of the user when in use, and the locking piece and the mounting sleeve have opposite magnetic poles. This design makes the locking piece and the inner wall of the mounting sleeve closely attached, thereby ensuring the stability of locking the bicycle seat, and is useful for promotion and use.
