[0015] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0017] The utility model will be further described below in conjunction with the accompanying drawings.
[0018] Please refer to Figure 1-3 The utility model is a foldable lining expandable luggage case, comprising a first box body 1 and a second box body 2, a connecting frame 3 is connected between the first box body 1 and the second box body 2, the upper and lower ends of one side of the connecting frame 3 are fixedly connected with connecting cloth belts 4, the end of the connecting cloth belt 4 away from the connecting frame 3 is fixedly connected to the first box body 1 and the second box body 2, the four corners of the inner wall of the first box body 1 are rotatably connected with supporting side panels 5, and the connecting cloth belt 4 is detachably connected to the second box body 2.
[0019] A plurality of connecting holes 7 are drilled around the inside of the connecting frame 3, and a plurality of T-shaped plug rods 6 are fixedly connected to the position of the supporting side panels 5 relative to the connecting holes 7. The T-shaped plug rods 6 are plugged into the connecting holes 7. When the T-shaped plug rods 6 on the supporting side panels 5 are aligned with the connecting holes 7 of the connecting frame 3, the T-shaped plug rods 6 are inserted into the connecting holes 7, and the L-shaped limiting plates 11 are clamped on the cross plates of the T-shaped plug rods 6 to limit the supporting side panels 5, so that the connecting frame 3 is connected to the No. 1 box body 1 together. An L-shaped slide groove 9 is drilled inside the No. 2 box body 2 and at the top of the connecting hole 7. The L-shaped slide groove 9 is slidably connected to the inside of the L-shaped limiting plate 11, and the L-shaped limiting plate 11 is clamped on the cross plate of the T-shaped plug rod 6. When the suitcase is to be placed, the L-shaped limiting plate 11 is pulled to move the L-shaped limiting plate 11 out of the connecting socket 7. The L-shaped limiting plate 11 is located inside the L-shaped slide groove 9 and is fixedly connected with a No. 2 spring 10 at one end away from the T-shaped plug rod 6. The No. 2 spring 10 is fixedly connected to the inner wall of the L-shaped slide groove 9. The interior of the connecting socket 7 is fixedly connected with a No. 1 spring 8, which contacts the T-shaped plug rod 6. The T-shaped plug rod 6 that loses the limitation of the L-shaped limiting plate 11 is moved out of the connecting socket 7 under the push of the No. 1 spring 8, and the supporting side plate 5 that loses the connection detaches from the connecting frame 3. The connecting frame 3 that loses the support of the supporting side plate 5 can be received into the No. 1 box body 1, thereby reducing the distance between the No. 1 box body 1 and the No. 2 box body 2.
[0020] Specifically, when the utility model is used, when the luggage case is needed, the supporting side plate 5 inside the first box body 1 is erected, and when the T-shaped plug rod 6 on the supporting side plate 5 is aligned with the connecting hole 7 of the connecting frame 3, the T-shaped plug rod 6 is inserted into the connecting hole 7, and the L-shaped limiting plate 11 is clamped on the horizontal plate of the T-shaped plug rod 6 to limit the supporting side plate 5, so that the connecting frame 3 and the first box body 1 are connected together, and the distance between the first box body 1 and the second box body 2 is increased, thereby increasing the storage space of the luggage case, and the first box body 1 and the connecting frame 3 and the connecting frame 3 and the second box body 2 are respectively connected together through the zipper of the box body, and the luggage case is closed;
[0021] When the suitcase needs to be placed, the L-shaped limiting plate 11 is pulled to move the L-shaped limiting plate 11 out of the connecting socket 7. The T-shaped plug rod 6 that has lost the limitation of the L-shaped limiting plate 11 is moved out of the connecting socket 7 under the push of the No. 1 spring 8. The supporting side plate 5 that has lost connection is detached from the connecting frame 3. The connecting frame 3 that has lost the support of the supporting side plate 5 can be stored in the No. 1 box body 1, reducing the distance between the No. 1 box body 1 and the No. 2 box body 2, thereby reducing the thickness of the suitcase and reducing the space required for storing the suitcase.
[0022] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
[0023] Other parts of the present invention not described in detail belong to the prior art and will not be described here.
[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
