Problems solved by technology
It should be pointed out that this synchronous braking mechanism that can be used for universal wheels solves the problem of inconvenient disassembly and assembly of universal wheels in the document "CN203528569U". During daily use, some small stones and other foreign objects are easy to get stuck in the hole, resulting in the failure of the brake pin to extend normally, which affects the reliability of the brake mechanism

The invention discloses a baby stroller, and relates to the technical field of baby and child products. The baby stroller includes a braking mechanism, a braking pin, a braking hook, a transmission part, a driving part, a braking pin reset component, and a braking hook reset component, wherein the braking mechanism includes braking teeth, the braking teeth are arranged on the side of a wheel, anda braking tooth groove is formed between the two adjacent braking teeth; the braking pin is arranged on the side, close to the wheel, of a fork arm, and the braking pin can move upward along the forkarm and is clamped in the braking tooth groove; the braking hook is mounted on a wheel carrier mounting seat and can move relative to the wheel carrier mounting seat, and the braking hook is providedwith a hook part; the transmission part is mounted on a wheel carrier and can move relative to the wheel carrier; the driving part is mounted on a stroller frame or the wheel carrier mounting seat andconnected with the braking hook; the braking pin reset component is mounted on the wheel carrier, can push the braking pin to reset by using the resilience force of the braking pin reset component, and drives the transmission part to reset; and the braking hook reset component is mounted on the wheel carrier mounting seat and can push the braking hook to reset by using the resilience force of thebraking hook reset component. Casters of the baby stroller can be all universal wheels, and the baby stroller has the advantages of convenient dismounting of the universal wheels and synchronous braking.
Description
technical field [0001] The invention relates to the technical field of baby products, in particular to a baby trolley. Background technique [0002] In recent years, with the development of the economy, baby trolleys have gradually become popular, and people have higher and higher requirements for the convenience and safety of the trolleys. For example, some countries mandate that baby strollers sold on the market must be able to achieve synchronous braking, that is, the user can brake both rear wheels at the same time when a single step on the brake (it is called "single pedal double brake" in the stroller industry). For fixed wheels, it is very easy to achieve synchronous braking, but for universal wheels, it is necessary to rely on ingenious structural design to take into account free steering and synchronous braking at the same time. [0003] The Chinese patent document "CN203528569U" discloses a linkage brake mechanism that can be used for universal wheels. It drives t...
