Problems solved by technology

[0003] However, in the past, the single-wheel brake only added a brake pedal to one side of the wheel, but not connected to the other side of the wheel. The disadvantage is that when the brake pedal is twisted and deformed, the brake block will be detached from the wheel and the brake will fail.

Abstract

The invention discloses a wheel structure of a baby stroller, which comprises wheels and wheel forks, wherein the wheels are installed on the wheel forks through wheel shafts. Both sides of each wheel forks are respectively pivoted with a connecting rod, and a brake step tread is arranged between the two connecting rods. Each wheel fork is provided with a connecting part which extends upwards, a brake shoe is sleeved on the connecting part, and a spring is connected between the brake shoe and the connecting part. An adapting part with an inclined plane is formed at the inner side of the brake step tread, a contact part placed above the inclined plane of the adapting part is convexly arranged on the brake shoe, and a limit part is convexly arranged at the lower part of the brake shoe. Each wheel is provided with a brake disc, and a plurality of brake slots are arranged at intervals on the periphery of the brake disc. The brake step tread can drive the brake shoe to move upwards and downwards through the inclined plane so as to enable the limit part of the brake shoe to insert or retreat the brake slots of the brake disc for braking or de-braking. The brake step tread is connected to the two sides of each wheel, so that brake failure due to the separation of the brake shoe and the wheels caused by the distortion of the brake step tread is avoided.

Description

technical field [0001] The invention relates to a wheel structure of a stroller. Background technique [0002] Currently on the market, the brake device of the baby stroller includes a brake seat, a wheel and brake teeth installed on the wheel shaft. A plurality of brake grooves are formed between each tooth of the brake teeth, and a brake pedal pivotally connected with the brake seat. There are brake pins on the pedals. When the user presses down the brake handle, the brake pin is inserted into the brake groove, so that the wheel cannot rotate; when the user lifts the brake pedal, the brake pin withdraws from the brake groove, so that the wheel can rotate freely. [0003] However, the conventional single-wheel brakes only add a brake pedal to one side of the wheel, but are not connected to the other side of the wheel. The disadvantage is that when the brake pedal is twisted and deformed, the brake block will be detached from the wheel and the brake will fail. Contents of...
