Referring to fig. 1 to 5, the appearance volume adjustable luggage of an embodiment of the present invention includes two shells 10, a connecting sheet 20 connecting the two shells 10 and enclosing an accommodating space with the two shells 10, a zipper assembly 30 mounted on the connecting sheet 20, and a positioning assembly 40 disposed inside the accommodating space and connected to the two shells 10, wherein the positioning assembly 40 can be folded at a certain angle to reduce the thickness of the luggage, and the zipper assembly 30 cooperates with the connecting sheet 20 to limit the position of the folded positioning assembly 40.

The two shells 10 are oppositely arranged, the connecting sheet 20 is made of freely bendable cloth or other bendable materials, the connecting sheet 20 is annularly arranged, and two side edges of the connecting sheet 20 are connected with the edges of the shells 10 in a knitting, bonding or other mode.

The zipper assembly 30 comprises two key tooth groups 31 and a zipper head 32 installed on the two key tooth groups 31, and when the zipper head 32 is stroked along the positive and negative directions, the two key tooth groups 31 matched with the zipper head are driven to be meshed or separated. The two key tooth groups 31 are arranged along the circumferential direction of the connecting piece 20, the two key tooth groups 31 are separately arranged on the connecting piece 20 in an extending state, and when the zipper head 32 drives the two key tooth groups 31 matched with the zipper head to be meshed, the two key tooth groups 31 pull the connecting piece 20 to be close to the middle part, the length of the connecting piece 20 after extension is shortened, and the thickness of the luggage case is further reduced.

In order to ensure that the connecting piece 20 can be fully extended and prevent the zipper head 32 from pulling the connecting piece 20 to make the heights of the shells 10 on different sides inconsistent, the key tooth group 31 comprises a straight section 311 and an inclined section 312, and the inclined sections 312 of the two key tooth groups 31 are close to each other in the end direction.

In this embodiment, the number of the positioning assemblies 40 is two, two sets of the positioning assemblies 40 are disposed at two opposite sides of the accommodating space, each positioning assembly 40 includes two rotating plates 41, two fixing plates 42, a first rotating shaft 43 inserted between the two rotating plates 41, a torsion spring 45 installed on the first rotating shaft 43 and limiting the rotation of the two rotating plates 41, and a second rotating shaft 44 inserted between the rotating plates 41 and the fixing plates 42, wherein the two rotating plates 41 are disposed between the two fixing plates 42, one side of each rotating plate 41 is pivoted to the other rotating plate 41 through the first rotating shaft 43, the two rotating plates 41 can rotate relatively, the other side of each rotating plate 41 is pivoted to the fixing plate 42 through the second rotating shaft 44, and the rotating plate 41 can rotate relative to the fixing plate 42 matched therewith. The lateral surface of rotating plate 41 is equipped with draw-in groove 411, torsion spring 45 both ends are blocked respectively and are located in the draw-in groove 411 of two rotating plate 41, and when two rotating plate 41 rotated around first axis of rotation 43 relatively, torsion spring 45 elastic deformation to two rotating plate 41 return are supported in the top. The fixed plate 42 is installed inside the two housings 10, and when the two rotating plates 41 rotate with each other, the fixed plate 42 is fixed to each other, so that the rotating plates 41 and the fixed plate 42 rotate around the second rotating shaft 44 in synchronization.

In the use, when the volume that needs reduce the suitcase occupies too big space in order to reduce the suitcase, press casing 10, make the junction between two rotor plates 41 inwards bend and fold, torsional spring 45 elastic deformation pulls zipper head 32 of zip fastener subassembly 30 again, makes two key tooth group 31 be in the state of complete lock, and two key tooth group 31 pulling connection piece 20 of complete lock are drawn close to the middle part, shortens the length after connection piece 20 extends, and then carries on spacingly to rotor plate 41 in rotor plate 41's return direction, and then reduces the thickness of suitcase.

In addition, an opening 50 is formed in one of the shells 10, a sealing element for sealing is disposed at an edge of the opening 50, in this embodiment, the sealing element is a zipper, in other embodiments, the sealing element may also seal the opening 50 by means of a snap, a magnetic attraction, and the like, and after the opening 50 is opened, an article may be placed into or removed from the opening 50.

The suitcase with the adjustable appearance volume has the advantages that: through setting up positioning assembly 40, zip fastener subassembly 30 and connection piece 20 on the suitcase, positioning assembly 40 can carry out certain angle folding to reduce suitcase thickness, zip fastener subassembly 30 cooperation connection piece 20 is spacing to positioning assembly 40 after folding, thereby realizes adjusting the suitcase volume according to the user demand, and the flexibility is good, convenient to use, and the practicality is strong, has stronger popularization meaning.
