Extensible luggage box

Abstract

The invention relates to an extensible luggage box. The extensible luggage box comprises a first box shell, a second box shell, an annular band and at least one telescopic device. The first box shell is provided with penetrating holes, and the first box shell and the second box shell are connected together through the annular band. Each telescopic device comprises a movable seat, a fixed seat and a positioning mechanism, wherein the movable seat is arranged on the first box shell, the fixed seat is arranged on the second box shell and sleeved with the movable seat in a penetrating mode, and the positioning mechanism is connected with the fixed seat and the movable seat and provided with a detent end which is exposed out of the first box shell through the corresponding penetrating hole. When the detent ends are not braked, the positioning mechanisms are in a locked state, and the movable seats cannot move relative to the fixed seats; when the detent ends are braked, the positioning mechanisms are in a relieving state, the movable seats can move relative to the fixed seats, and thus a user can uniformly extend the storage capacity of the luggage box as needed.

Description

Technical field [0001] The invention relates to a luggage case, in particular to an expandable luggage case. Background technique [0002] Currently commercially available suitcases are mainly divided into two types: soft-shell suitcases and hard-shell suitcases. Some soft-shell suitcases have retractable functions. As long as the specific device (such as zippers, etc.) is removed, the items in the suitcase can be added And expand a certain storage capacity to solve the problem that the original capacity cannot fully store the items. However, when the items are not placed evenly, the extent of expansion of the soft shell box will be inconsistent, the luggage box will be deformed, and the items in the box shell During the transportation of the luggage, it is also easy to cause damage due to the external force squeezing the shell itself. Compared with the soft shell, the hard shell box on the market can reduce the probability of damage to the item, but it does not have the expansio...

Problems solved by technology

[0002] At present, the suitcases on the market are mainly divided into two types: soft-shell boxes and hard-shell boxes. Some of the soft-shell boxes have a retractable function. And expand a certain storage capacity to solve the problem that the original capacity cannot fully store items. However, when the items are not placed evenly, the degree of expansion of the soft shell box will be inconsistent, the suitcase will be deformed, and the items in the box shell During the transportation of the suitcase, it is also easy to be damaged due to the extrusion of the suitcase itself; compared with the soft-shell suitcase, although the commercially available hard-shell suitcase can reduce the probability of damage to the items, it does not have the ability to expand and contract. Therefore, the use capacity of hard-shell cases is still limited; therefore, how to design a suitcase that can evenly expand the storage capacity and reduce the damage rate of items has become a goal that the industry is trying to achieve.
