Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a locking device and a luggage case with the locking device. Background technique [0002] In the field of boxes, it is divided into two types: fixed volume and variable volume. For the former, the size of the use space inside the box is fixed, and the storage space inside the box cannot be changed according to actual needs, and the frequency of use of the box (especially the suitcase) is low, and most of the time it is in an idle state. In terms of large and small cases, it will take up a certain amount of storage space, which is not convenient for the storage of the case. [0003] For the latter, it can change the storage space inside the box according to the actual storage needs, so that the practicability of the box is better, but for the current variable volume box, it is mainly in the original box.

Problems solved by technology

For the former, the size of the use space inside the box is fixed, and the storage space inside the box cannot be changed according to actual needs, and the frequency of use of the box (especially the suitcase) is low, and most of the time it is in an idle state. For large and small boxes, it will take up a certain amount of storage space, which is not convenient for the storage of boxes

[0003] For the latter, it can change the storage space inside the box according to the actual storage needs, so that the practicability of the box is better, but for the current variable volume box, it is mainly in the original box. On the basis of adding a detachable box, the two are connected together through a locking structure. For example, in the application with the authorization announcement number CN208114187U and the name "A Luggage Box with Adjustable Size", it is locked by a zipper. The locking structure is used to realize the connection between the movable box, the top box, and the bottom box. This method is not convenient and labor-saving in actual use.
