Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically to a folding mechanism with a limiter. Background Technology

[0002] A folding bicycle is a type of bicycle. Generally, a folding bicycle consists of a folding frame joint and a folding seat tube joint. By folding the frame, the front and rear wheels are folded together, reducing the length by approximately 45%. The folded bicycle can be easily placed in a folding bag or the trunk of a car. No external tools are needed during folding; the bicycle can be manually unfolded. The seatpost serves as a support point to ensure stability when folded. Folding bicycles are convenient to carry and use, comfortable to ride, and manufactured using mature technology.

[0003] To meet the portability requirements of cycling products, a folding mechanism with limiters has been designed. This folding mechanism works in conjunction with a folding bicycle to make the overall structure easier to operate and install. Summary of the Invention

[0004] A folding mechanism with a limiter includes: an upper seat, a lower seat, a trigger, a connecting structure, a main tube, upper and lower handlebar covers, a locking screw, an adjuster wrench, an adjuster screw, an adjusting clamp, a telescopic tube, a rubber pad, a plastic sleeve, an upper and lower seat connecting shaft, and a handlebar shaft.

[0005] The handlebar cover consists of two parts, which are arranged opposite each other and have grooves. The grooves engage with the handlebars, and the handlebar cover is installed together with the handlebars by locking screws.

[0006] The lower half of the handlebar cover is connected to a telescopic tube.

[0007] The upper half of the main tube is provided with a shrinkage groove;

[0008] The plastic sleeve is fitted inside the main tube, and the top of the plastic sleeve is provided with a ring edge that abuts against the top of the main tube.

[0009] The telescopic tube is inserted into the plastic sleeve;

[0010] The adjusting ring is sleeved on the outer wall of the main tube, and a pair of through holes are provided on one side of the adjusting ring; one end of the adjuster screw is a nut, and the other end is a hammer rod, and the adjuster screw passes through the pair of through holes of the adjusting ring;

[0011] The adjuster wrench also has a pair of through holes, through which the hammer head of the hammer rod passes.

[0012] The rubber pad is placed on the inner wall of the adjusting ring to reduce shock and increase friction.

[0013] The upper and lower seats are arranged opposite to each other, and the bottom of the main body tube is fixed together with the upper seat; a pair of through holes are provided on one side of the upper seat and a mounting hole is provided on the other side.

[0014] A pair of through holes are provided on each side of the lower seat;

[0015] The upper seat and the lower seat are rotatably connected together on one side by a connecting shaft between the upper and lower seats;

[0016] The mounting hole of the upper seat is connected to one end of the connecting structure;

[0017] The bottom of the trigger is rotatably connected to a through hole on one side of the lower seat via a handle shaft, and the other end of the connecting structure is located inside the trigger; the trigger is provided with a slot, which engages with one end of the connecting structure.

[0018] The beneficial effects of this utility model are as follows:

[0019] Compared to the traditional single-lock design of folding bicycles, this invention uses a trigger that works in conjunction with the upper and lower seats. After locking, the opening angle of the connecting structure is within a reasonable range and matches the vehicle's mounting position. Attached Figure Description
