Travel suitcase with stairs-climbing mechanisms with sliding wheels

Abstract

The invention relates to the technical field of articles for daily use, in particular to a hand-pulling type travel suitcase, which is provided with a plurality of stairs-climbing mechanisms with sliding wheels; the stairs-climbing mechanisms are matched with landing wheels; each stairs-climbing mechanism comprises a sliding wheel part and a concave seat part with fixed protective covers; the sliding wheel part is provided with a wheel-arranging box; and the box surface of the convex seat part is provided with fixed protective covers for wrapping part of box corners or angle edges. The hand-pulling type travel suitcase not only can travel on flat ground, but also can travel smoothly in the environments with rugged ground of stairs, steps, slopes and the like, has simple and durable structure, beautiful appearance and convenient assembly, also can have the function of reducing vibration, and can be adjusted according to the conditions of ground environment so as to lead a user to drag the travel suitcase more relaxedly with less effort.

Description

technical field [0001] The invention relates to a daily necessities, in particular to a suitcase convenient for going up and down stairs, steps, slopes and other rough and uneven ground environments. Background technique [0002] When people travel, if they need to bring larger items, they often use hand-held suitcases. The hand-held suitcase saves a lot of physical strength for people during the journey, but when going up and down the stairs, the suitcase must be lifted to continue moving forward. If the items in the suitcase are large, a lot of physical strength will be consumed. If you use People with limited strength, such as the elderly, children, pregnant women, etc., may even be unable to move forward. Therefore traditional pull-type suitcase still has comparatively prominent defective in this respect. In order to solve the defects of this hand-pulled suitcase when going up and down stairs, people have thought about various methods. Such as the application number i...

Problems solved by technology

Due to the fixed installation of the tracks in this design, when there is no need to go up the stairs, the friction in the process of pulling the box is relatively large, and it is more laborious

And because its angle is fixed, it is not suitable for going up and down a variety of stairs with different heights.

[0003] And because when going up and down stairs, the stair-climbing mechanism designed by the general suitcase will cause the box to have certain bumps, as well as the friction between the box body and the edge of the building and the vibration of the stair-climbing mechanism due to the pull of the edge of the building and the oppression of the weight of the box. factors such as friction and friction, so higher requirements are put forward for the anti-seismic ability of the mechanism and the fixing method and anti-wear method of the climbing mechanism in the box.
