Description

A wheel installation structure of a stroller for young children

technical field

The utility model relates to a wheel installation structure of a stroller for young children.

Background technique

At present, there are many kinds of baby strollers in the children's products market, with novel and practical functions. However, some parents feel that the steps are very cumbersome and time-consuming when collecting and transporting baby strollers.

Therefore, the energy of the parents of the busy babies has been scattered, and many inconveniences have been brought to life.

Contents of the invention

In order to solve the above problems, the utility model provides a wheel installation structure for children's stroller, which is characterized in that: the wheel is rotatably installed on the axle, the axle is inserted into the axle sleeve on the frame, and the axle sleeve has The movable engaging mechanism fixes the axle. The movable engaging mechanism includes a groove on the axle, a bayonet pin that can extend into the groove, a return spring, and a button that can control the bayonet pin to expand and contract. The bayonet pin is located in the shell outside the shaft sleeve, and the shaft sleeve is provided with a positioning hole corresponding to the groove position on the axle. connect.

The working principle is: the button drives the detent to move and then the axle is disengaged from the engaging mechanism, and at the same time, the wheel can be removed by lightly pulling the wheel outward.

The beneficial effect of the utility model is that the wheel can be quickly and easily disassembled on the cart frame, which saves time for parents, and is a time-saving and efficient push-wheel button-type quick-disassembly structure. And this push-button quick release structure can also be used on supermarket carts, luggage carts and other carts that need to be disassembled and stored.
