Abstract

The invention provides a luggage box roller mechanism capable of climbing stairs. The mechanism comprises six roller sheets and a telescoping mechanism. Six roller sheets are symmetrically arranged two by two in the horizontal direction and are enclosed to form an ellipsoid. Three roller sheets in the left side and three roller sheets in the right side are connected by the telescoping mechanism. Every two symmetric roller sheets are fixedly connected on the opposite external edges. The telescoping mechanism comprises a first hinge end, a second hinge end, and three parallel four-bar linkages.Three ends of each parallel four-bar linkage are hinged to the first hinge end, the second hinge end, and one roller sheet; through the telescoping mechanism, six roller sheets can be spread out, andafter six roller sheet are spread out, three roller sheets in the same side are distributed in a triangular shape. The provided mechanism can freely roll on flat ground and is capable of climbing stairs and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of luggage components, in particular to a luggage roller mechanism capable of going up and down steps. Background technique [0002] Bags are a very common tool used in daily life, especially bags with pull rods. Existing trolley bags are all equipped with rollers to facilitate dragging when walking. When going up and down the steps, the trolley bags cannot cross the steps, and the bags need to be lifted to pass through the steps. The quality of the bags with articles is generally large, and it takes a lot of effort to lift the bags and pass through the steps, which brings inconvenience to the users. Contents of the invention [0003] The object of the present invention is to provide a luggage roller mechanism capable of going up and down steps. [0004] In order to achieve the above object, the present invention adopts the following technical scheme: a luggage roller mechanism that can go up and down s...
