AI Technical Summary

Problems solved by technology

The center of gravity of existing casters is relatively high, and the wheel seat is biased to one side, so the torque is relatively large, and it is easy to be damaged; the structure is cumbersome and requires many components, such as the rotating shaft needs to be fixed with nuts, and the connection relationship is also very complicated, and the processing and assembly procedures follow. increase, and thus higher cost

Abstract

The invention discloses a baby carriage adapting to go up and down stairs. The baby carriage comprises a wheel shell, a wheel core which is connected with the wheel shell in a clamping mode and can rotate around the wheel shell, and a roller which is installed on the wheel core through a rotation shaft. The baby carriage adapts to go up and down stairs, the contact area between the rollers and theground is large, and thus the baby carriage is stable; the center of gravity is low and the moment of force is small, so that work is reliable; and the baby carriage adapting to go up and down stairsis simple in structure and convenient to machine and assemble.

Description

technical field [0001] The invention relates to casters, in particular to a stroller adapted to go up and down stairs installed under equipment that needs to be frequently moved. Background technique [0002] Casters are commonly used items, such as refrigerators and washing machines for household appliances, trolleys for hotel food delivery, and swivel chairs for household use. After installing a stroller suitable for going up and down stairs, it is more convenient to move. [0003] A common stroller suitable for going up and down stairs is generally divided into two modules, a steering module and a roller module. The former allows the casters to rotate 360°, allowing the mobile device to turn in any direction without hindrance; the latter enables the mobile device to move freely. In the prior art, the center of gravity of the caster is relatively high, and the wheel seat is biased to one side, so the torque is relatively large, and it is easy to be damaged; the structure ...
