Abstract

The invention provides a trolley wheel adjusting device. The trolley wheel adjusting device comprises external adjusting mechanisms and internal adjusting mechanisms, wherein, the external adjusting mechanisms and the internal adjusting mechanisms are arranged on a trolley, each external adjusting mechanism comprises an external lifting unit, and each internal adjusting mechanism comprises an inner lifting unit, and the internal adjusting mechanisms and the external adjusting mechanisms are arranged mutually independent. According to the trolley wheel adjusting device, the two external adjusting mechanisms and the two internal adjusting mechanisms which are mutually dependent and mutually hands-off are arranged in the trolley wheel adjusting device, and the trolley wheel adjusting device is alternately adjusted by the external adjusting mechanisms and the internal adjusting mechanisms, so that the trolley with the trolley wheel adjusting device easily and flexibly strides over a plurality of continuous thresholds; and in addition, the external adjusting mechanisms and the internal adjusting mechanisms is subjected to motion transmission through rod pieces or gears, so that the trolley wheel adjusting device can be steady and reliable in transmission.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an adjusting device, in particular to a wheel adjusting device. Background technique [0002] At present, the commonly used trolleys are only suitable for carrying items on flat ground. In the actual moving process, it is very difficult to carry heavy things over the threshold, and some even move the items from the cart due to the threshold. It is very inconvenient to roll up and down. [0003] Chinese invention patent (CN 1693128A) discloses a foldable cross-threshold trolley, including a flat plate, casters and armrests, the casters are installed under the flat plate, and the handrail is connected to one end of the flat plate, characterized in that: at the other end of the flat plate One end of the other flat plate is hinged, castors and handrails are respectively provided on the bottom and the other end of the other flat plate; a plurality of transversely parallel rollers are...
