Description

Technical Field

[0001] The utility model relates to the technical field of luggage cases, and more specifically, to a luggage case with a telescopic structure. Background Art

[0002] Existing luggage cases are divided into soft-sided cases and hard-sided cases. Both cases include a case cover and a case body, which are connected by a zipper. In order to increase the storage space of the case, a telescopic mechanism is usually provided on the case cover of the soft-sided case. When the telescopic mechanism is extended, the height of the case cover can be increased, thereby increasing the volume of the case. When the mechanism is retracted, the volume of the case is reduced and restored to a normal size, thereby increasing practicality.

[0003] This telescopic mechanism is mostly realized by a zipper. When the zipper is opened, the box folded in the zipper can be opened to increase the height of the box and increase the storage space. However, in this way, since the expansion fabric is a soft material, the overall structure of the unfolded suitcase is relatively unstable, which affects normal use.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0007] By adopting the above technical solution, when in use, the main box body and the sub-box body can be separated by the first zipper, so that the suitcase can be opened. When it is necessary to expand the volume inside the sub-box body, the first retractable cloth strip can be unfolded by pulling the first and second zippers, thereby increasing the distance between the connecting frame and the sub-box body, thereby increasing the volume of the suitcase, and the sub-box body and the connecting frame are positioned by the positioning component, thereby ensuring the stability of the suitcase when in use.

[0008] The utility model is further configured as follows: a second retractable cloth strip is provided on the peripheral side of the connection frame and the auxiliary box body and located on the inner side of the first retractable cloth strip, the width of the second retractable cloth strip is greater than the first retractable cloth strip, and two of the second retractable cloth strips are provided with a third zipper along their peripheral side.

[0009] The utility model is further configured as follows: a positioning edge is arranged along the circumference of the inner wall of the connection frame, and the four corners of the positioning edge are fixedly connected with horizontally arranged limiting rods, and the four corners of the auxiliary box body are provided with limiting grooves for sliding connection of the limiting rods.

[0010] The utility model is further configured as follows: a spring is arranged in the limiting groove, and two ends of the spring are fixedly connected to the end inner wall of the limiting groove and the end of the limiting rod.

[0011] The utility model is further configured as follows: the positioning assembly is provided with two groups of positioning rods which are respectively arranged at the top end and the lower end inner wall of the auxiliary box body of the connecting frame; the positioning assembly includes a hinge shaft which is fixedly connected to the inner wall of the connecting frame; a rotating rod is hinged on the hinge shaft; a positioning block is provided on the end side wall of the rotating rod; a positioning groove is opened on the side wall of the positioning block; and a plurality of positioning rods which are fixedly connected to the inner wall of the auxiliary box body and are inserted into the positioning groove.

[0012] The utility model has the following beneficial effects: when in use, the main case and the auxiliary case can be separated by the first zipper, so that the suitcase can be opened; when the volume inside the auxiliary case needs to be expanded, the first and second zippers can be opened to unfold the first retractable cloth strip, thereby increasing the distance between the connecting frame and the auxiliary case, thereby increasing the volume of the suitcase; and the auxiliary case and the connecting frame are positioned by the positioning component, thereby ensuring the stability of the suitcase when in use.

[0021] As shown in the figure, a suitcase with a telescopic structure includes a main box body 1 and a sub-box body 2, a connecting frame 3 is arranged between the main box body 1 and the sub-box body 2, a connecting cloth strip 4 and a first zipper 5 are arranged between the main box body 1 and the connecting frame 3, a telescopic mechanism is arranged between the connecting frame 3 and the sub-box body 2, the telescopic mechanism includes a first telescopic cloth strip 6 arranged on a side opposite to the connecting frame 3 and the sub-box body 2 and arranged along the circumference thereof, the two first telescopic cloth strips 6 are each provided with a second zipper 7 along the circumference thereof, and a positioning component is arranged between the connecting frame 3 and the sub-box body 2.

[0022] When in use, the main box body 1 and the sub-box body 2 can be separated by the first zipper 5, so that the suitcase can be opened. When it is necessary to expand the volume inside the sub-box body 2, the first and second zippers 7 can be opened to unfold the first retractable cloth strip 6, thereby increasing the distance between the connecting frame 3 and the sub-box body 2, thereby increasing the volume of the suitcase, and the sub-box body 2 and the connecting frame 3 are positioned by the positioning component, thereby ensuring the stability of the suitcase when in use.

[0023] A second retractable fabric strip 8 is further provided on the peripheral side of the connecting frame 3 and the auxiliary box body 2 and located on the inner side of the first retractable fabric strip 6. The width of the second retractable fabric strip 8 is greater than that of the first retractable fabric strip 6. The two second retractable fabric strips 8 are provided with a third zipper 9 along the peripheral side thereof. When the volume of the suitcase needs to be further expanded, the second retractable strip can be stretched by opening the third zipper 9, thereby further expanding the volume of the suitcase, and the connecting frame 3 and the auxiliary box body 2 are positioned by the positioning assembly, so that the volume of the suitcase can be expanded according to the use needs.

[0024] The inner wall of the connection frame 3 is provided with a positioning edge 10 along its circumference, and the four corners of the positioning edge 10 are fixedly connected with the horizontally arranged limiting rods 11, and the four corners of the auxiliary box body 2 are provided with limiting grooves 12 for the limiting rods 11 to be slidably connected. A spring 13 is provided in the limiting groove 12, and the two ends of the spring 13 are fixedly connected to the inner wall of the end of the limiting groove 12 and the end of the limiting rod 11. The limiting rod 11 is used to improve the stability of the connection between the connection frame 3 and the auxiliary box body 2. The spring 13 is in a compressed state. Under the elastic force of the spring 13, when the second zipper 7 and the third zipper 9 are opened, the first retractable cloth and the second retractable cloth can be stretched, so that the volume of the box body is expanded.

[0025] The positioning assembly is provided with two groups, which are respectively arranged on the top end and the lower end inner wall of the auxiliary box body 2 of the connecting frame 3.
