Description

Technical Field

[0001] The utility model relates to the technical field of luggage case expansion structures, in particular to a luggage case telescopic enclosure structure. Background Art

[0002] Users' space requirements for suitcases will vary depending on the travel period and the climate of the destination, and they will need to carry different clothes and suitcases of corresponding volumes. For example, when the weather at the traveler's departure place is relatively warm and the destination is relatively cold, the user will put the warm clothes in the luggage, and at this time the user will have a greater need for space in the suitcase. After arriving at the destination, the warm clothes are taken out of the luggage and the interior of the suitcase will be empty, but the user hopes that the external volume of the suitcase will not be too large to affect the convenience of travel or action. The opposite is true for the return trip. When the user returns to a warmer climate, he or she needs to put the warm clothes in the suitcase, and then the suitcase needs to have enough volume. In addition, the user may also purchase items at the destination, such as souvenirs, which places higher requirements on the volume of the suitcase. At the same time, the user hopes to use only one suitcase to solve the volume requirements under different conditions if possible.

[0003] Therefore, the suitcase has a retractable and expandable function which can not only meet the convenience of users, but also can meet the needs of users with different capacity requirements.

[0004] The existing technical solutions in the industry are roughly divided into two structural types: 1. Zipper structure (for example: CN215014105U); 2. Telescopic bracket with plastic structure (for example: CN102578779A);

[0005] Zipper structure: There are many variations of zipper-type telescopic structures. For example, the main compartment zipper is parallel to the telescopic zipper. When the telescopic zipper is closed, the space can be contracted to reduce the volume of the suitcase. When the telescopic zipper is opened, a circle of telescopic fabric can be extended from the inside of the zipper. Since the telescopic fabric is made of soft fabric and can be stretched freely to a certain distance, the thickness of the suitcase can be increased to release a certain amount of internal space.

[0006] The disadvantage is that when the telescopic zipper of the suitcase is opened and closed, the user needs to open or close the zipper around the suitcase, which is difficult and inconvenient to operate. At the same time, after the telescopic zipper is opened, the telescopic area is connected by fabric, which is relatively soft. Therefore, the front and rear shells of the suitcase do not have a hard connection structure, resulting in misalignment, tilting, shaking and other problems, which makes it difficult for users to push and causes trouble to the user experience.

[0007] Telescopic bracket with plastic structure: This structure uses a hard plastic component with telescopic function. The component is divided into two ends, which are fixed to the front and rear shells of the suitcase respectively. The front and rear shells of the suitcase need to be connected with cloth, and the user closes the telescopic area. This structure generally uses at least two groups, which are fixed to the two side walls of the suitcase respectively. The user can control the volume of the suitcase from the inside of the suitcase by operating the two telescopic components fixed to the side walls of the suitcase.

[0008] The disadvantages are: the manufacturing cost of the structural component is high and not conducive to production and manufacturing; in addition, the user needs to operate the two telescopic components separately from the inside of the box and manually lift the two sides to expand or press down to shrink the space. This is very inconvenient for user operation and seriously affects the user experience. Utility Model Content

[0009] 1. Technical issues to be solved

[0010] In view of the deficiencies in the prior art, the utility model provides a retractable enclosure structure for a luggage case, which solves the problems raised in the above-mentioned background technology.

[0011] (II) Technical solution

[0012] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0013] A retractable luggage enclosure structure comprises a left half shell and a right half shell, the left half shell and the right half shell are opened and closed by an axis and a zipper structure, universal wheels are arranged at the bottom of the left half shell and the right half shell, an expansion structure is arranged on the right half shell, platforms or steps connected to the left half shell and the right half shell are arranged on both sides of the expansion structure for engaging the foldable expansion structure.

[0014] Furthermore, the right half shell is divided into a front shell and a rear shell, wherein the outer diameter of one end of the telescopic enclosure structure connecting the two ends of the front shell and the rear shell is larger than the other end.

[0015] Furthermore, the expansion structure is a foldable soft rubber structure.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a luggage case telescopic enclosure structure, which has the following beneficial effects:

[0018] The utility model realizes the volume expansion and contraction of the suitcase through the self-foldable soft rubber structure. In the contracted state, there is no need to add an expansion zipper to stabilize the suitcase in the contracted state, thereby reducing the processing procedures, the number of material types, and facilitating production management.

[0019] When the user needs to expand the suitcase to a larger capacity, there is no need to open the expansion zipper. The user only needs to stretch the suitcase front and back to use it, which greatly facilitates user operation. When the suitcase is in the expanded state, it can still be stably in the expanded state. The stability of the front and rear shells connected by soft glue is better than the conventional zipper and fabric structure. When the user pushes the suitcase, the suitcase is more stable, and there will be no problems with the traditional telescopic wall structure such as shaking and wheels not moving in a straight line due to the soft connection of the telescopic wall.
