The four-side folding luggage with the pair of unlocking locks comprises a case body 10, a zipper assembly 20 arranged on the case body 10, a tooth stopping assembly 30 arranged on the zipper assembly 20, and a pair of unlocking locks 40 arranged on the case body 10. It is contemplated that the four-sided suitcase with the pair of unlocking mechanisms may include other functional modules, such as handles, pull rod assemblies, pulley assemblies, etc., which are well known to those skilled in the art and will not be described in detail herein.

The box 10 may be a box-shaped structure formed by injection molding of plastic, and includes an upper cover 11 and a lower cover 12 that are fastened to each other. The upper cover 11 and the lower cover 12 have substantially the same structure, and when the upper cover 11 and the lower cover 12 are fastened together, a space is formed for a user to receive articles.

The zipper assembly 20 includes a double-layered zipper 21, and two sliders 22 respectively disposed on the double-layered zipper 21. The double-layer zipper 21 is an explosion-proof zipper, so that after the double-layer zipper 21 is closed, the case can not be opened by any sharp device on the premise of not damaging the double-layer zipper 21, and the case can be opened and closed at four sides. Because for the case provided with the single-layer zipper, a large number of experiments prove that the zipper can be opened only by using a sharp hard object. This makes the single layer zipper unsuitable for four-sided opening and closing, as the entire case is completely opened by merely poking the single layer zipper. The double-layered zipper 21 is a prior art, such as that disclosed in patent No. 201220248939.6 entitled single-ended double-layered zipper, and the structure and operation thereof will not be described in detail herein, and specifically, the double-layered zipper 21 includes an upper stringer 211 sewn to the upper cover 11, and a lower stringer 212 sewn to the lower cover 12. The two sliders 22 have the same structure, and the specific structure thereof is disclosed in patent No. 201220248939.6, and will not be described in detail herein. The slider 22 includes a release side 221, an engagement side 222 opposite the release side 221, and a pull tab 223 disposed between the release side 221 and the engagement side 222. To achieve the four-sided opening and closing, when the two sliders 22 are disposed on the upper and lower stringers 211, 212, the disengaged sides 221 of the two sliders 22 are disposed to face each other, that is, when the two sliders 22 are assembled, one end of the upper and lower stringers 211, 212 is inserted from the disengaged side 221 of one slider 22 and is inserted from the engaged side 222 of the other slider 22. And thus the engaging sides 222 of the two sliders 22 are disposed opposite each other when the two sliders 22 are disposed on the upper and lower links 211, 212. In order to assemble the two sliders 22 to the lower and lower stringers 211, 212, two aligned ends of the upper and lower stringers 211, 212 may be respectively provided with a plunger having a tapered structure so that both the upper and lower stringers 211, 212 can be inserted and assembled to the double-layer stringer 21 from the engaging side 222 of the slider. When the teeth of the upper and lower chains 211, 212 are made of plastic, the tapered structure is formed by sintering. Meanwhile, the tapered structures of the upper and lower chains 211, 212 are disposed at the ends of the upper and lower chains 211, 212 in the same direction. If the insert pin does not have the tapered structure, the ends of both the upper and lower zipper tapes are flush, so when the ends of the upper and lower zipper tapes are inserted into the engaging side 222 of the slider 22, the flush structure will abut against the connecting column of the two flat plates of the slider 22, thereby preventing the engaging side 222 of the slider from being assembled to the upper and lower zipper tapes 211, 212. The pull tab 223 is used for pulling the slider 22 to open and close the double-layer zipper 21. With the existing slider 22, the pull tabs 223 are all in a straight strip shape, so that the manufacturing is convenient, and the cost can be reduced.
