Abstract

The invention discloses a cart with extension-type wheels. Extension-type wheel sets are mounted in the front and in the back of the bottom of a cart carriage. Each extension-type wheel set comprises a wheel, a connecting-rod extension mechanism and a hydraulic cylinder. Each pair of extension-type wheel sets can be adjusted to ascend and descend within a certain range according to needs, so that when the cart needs to pass two ground surfaces different in height, the height of the extension-type wheel sets can be adjusted sequentially, and the cart can cross an obstacle caused by the ground surfaces different in height stably. The trouble of inconvenience in passing can be omitted particularly when the cart carries a plenty of goods; since the extension-type wheel sets are adjusted to ascend and descend in pairs, the goods carried in the cart can be kept horizontal as far as possible during passing, and side tilt is reduced.

Description

technical field [0001] The invention belongs to transportation equipment, in particular to a cart with retractable wheels. Background technique [0002] Cart (or trolley, trolley) is a small and convenient means of transportation. Because of its simple structure and convenient use, it is mainly used for temporary transportation of some materials and equipment. However, in some high-rise buildings, there are situations such as different floor heights between rooms, and it is generally difficult for carts to pass through smoothly. It is laborious to use manpower to carry, and it is not easy to ensure the stability of the equipment, and the transportation efficiency is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cart with retractable wheels that is reasonable in design, convenient and practical. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the follo...
