Problems solved by technology

However, uneven road conditions such as steps are inconvenient for traveling with suitcases
In this regard, people have made some improvements to the runner structure of the suitcase, such as adopting single-wheel paired type, lever roller type, three-wheel conjoined structure, etc. In other words, there are also the following obvious defects: the synchronization of the runners is not high, the durability is not strong, the stability of operation is not high, the shock absorption effect is not good, the operation is not smooth, and it is labor-saving, etc.

Embodiment Construction

[0019] In the figure, the trolley box that can walk on the steps includes two runners and conductors symmetrically arranged on both sides of the rear of the trolley box. The trolley box consists of a box body 1, a box cover 2, a box lock chain 3 and Consists of 4 tie rods. Each runner group includes a conductive tube 7 and three open tubes 16 communicating with the conductive tube at intervals, that is, the conductive tube 7 and the back, middle and front three connected to the conductive tube. The middle opening pipe 16 is made as a whole. The runner group is composed of front runners, intermediate runners, rear runners and related accessories. The conduction pipe contains liquid (or compressed gas) medium 6 and the conduction pipe is fixedly connected with the support plate 15. The support plate is fixedly connected with the box body, and the work of the two runners does not interfere with each other. The open tube is sealed and equipped with a piston rod 9 which is connected...

Abstract

The invention discloses a draw-bar box walking on steps. The draw-bar box comprises two rotating wheel sets symmetrically arranged on the two sides of the back portion of the draw-bar box. Each rotating wheel set comprises a conduction device (7) with three parallel opening pipes (16); piston rods (9) are sealed and installed in the opening pipes and connected with a back rotating wheel (12), a middle rotating wheel (13) and a front rotating wheel (14) respectively through supports (10) and rotating shafts (11), wherein the back rotating wheel (12), the middle rotating wheel (13) and the front rotating wheel (14) are parallelly arranged in an adjacent mode; the back rotating wheel, the middle rotating wheel and the front rotating wheel are sequentially reduced in diameter, the length of the opening pipes corresponding to the back rotating wheel, the middle rotating wheel and the front rotating wheel is sequentially increased, the outer-end distance of the back rotating wheel and the front rotating wheel is larger than the length of the angular line of one step, and the diameter of the back rotating wheel is larger than a half of the height of a single step (5). The draw-bar box walking on steps is compact and simple in structure and convenient o manufacture and use; the rotating wheels reversely link, the synchronism is high, and the vibration reducing performance is high; the uneven road conditions such steps are adapted, more force is saved during walking, and the operating effect is good.

Description

Technical field [0001] The invention relates to a luggage case, in particular a trolley-type luggage case that can walk on steps and flat roads. Background technique [0002] Luggage is an important travel tool for humans. Existing suitcases are also called trolley suitcases. They are generally equipped with walking wheels at the bottom and attached retractable or foldable trolleys to facilitate walking, but when they encounter steps or obstacles , Not only lack of basic guarantee for the stability of walking, but also the bottom of the suitcase will always rub against the step surface or obstacles, resulting in damage to the suitcase. Carrying on one's shoulders is a common method for surmounting steps and roadblocks, but lifting and suspending the suitcase makes the suitcase lose its proper portability and labor saving function, which is a helpless move. Steps, also called stairs and stairs, are an important part of the road. They are very common in stations, docks, hotels, sh...
