[0065] like Figures 1 to 3As shown, the embodiment of the present disclosure provides a detachable bag. It includes a bag body 1, a cover body 2, a slider 3 and a sealing device 4. The bag body 1 has a accommodating space 11 and one end is an open end 12, and a first toothed chain belt 14 is arranged on the outer side of the open end 12 along the circumferential direction, and a first notch 13 is formed at the confluence of the first toothed chain belt 14; the cover body 2 is covered on the side of the open end 12 of the bag body 1 and a second toothed chain belt 22 is arranged along the edge of the cover body 2, and a second notch 21 is formed at the confluence of the second toothed chain belt 22, wherein the position of the second notch 21 corresponds to the first notch 13; the slider 3 is installed on the first toothed chain belt 14 and the second toothed chain belt 22 through the first notch 13 and the second notch 21 to mesh the first toothed chain belt 14 and the second toothed chain belt 22; and the sealing device 4 covers the first notch 13 and the second notch 21, and is used to keep the chain teeth engaged and stop the slider 3.

[0066] With the detachable luggage provided by the embodiment of the present disclosure, the bag body 1 and the cover body 2 of the luggage can be separated, so that the cover body 2 can be easily replaced to meet the user's personalized requirements for the cover body 2. Preferably, the first notch 13 and the second notch 21 are located close to each other, and can be directly opposite or staggered by a certain distance, and the combination of the two is collectively referred to as a notch. When the slider 3 enters, the first notch 13 and the second notch 21 can be folded at a certain angle to facilitate the entry of the slider 3. The first and second tooth chain belts 14 and 22 are used in pairs and are called zippers. The ends of both are located at the notch, so that the slider 3 can be installed on the first and second tooth chain belts 14 and 22 through the notch. There is no stopper component at the end of the first and second tooth chain belts 14 and 22, which acts as a stopper component for the slider 3 after being fixed to the first and second tooth chain belts 14 and 22 by the sealing device 4. At the same time, the first and second tooth chain belts 14 and 22 are fixed. The first notch 13 and the second notch 21 in the sealing device 4 are all covered, so that the zipper is completely closed, which improves the overall aesthetics. The cover body 2 includes a first edge and a second edge, and the first edge and / or the second edge is provided with a second fastener belt 22 so that the cover body 2 can be used on both sides, thereby improving the use value.

[0067] like Figure 4 As shown, preferably, the first fastener belt 14 includes a first fastener belt 141 and a first fastener chain 142. The first fastener belt 141 is connected to the bag body 1 and surrounds the open end 12 of the bag body 1; the first fastener chain 142 is arranged along the outer side of the first fastener belt 141. The second fastener belt 22 includes a second fastener belt 221 and a second fastener chain 222. The second fastener belt 221 is connected to the cover body 2 and surrounds the cover body 2; the second fastener chain 222 is arranged along the outer side of the second fastener belt 221. Among them, the first notch 13 or the second notch 21 is closed at the confluence of the fastener belts.

[0068] Specifically, the zipper is composed of a chain belt and chain teeth. The inner side of the first chain belt 141 is arranged around the open end 12 of the bag body 1. The outer side of the first chain belt 141 is provided with first chain teeth 142 one by one. The second chain belt 221 and the second chain teeth 222 are also provided in the same manner and are symmetrical to the first chain belt 141 and the first chain teeth 142. The first notch 13 is closed at the confluence of the first chain teeth 14. The second notch 21 is closed at the confluence of the second chain teeth 22.

[0069] like Figure 3 to Figure 4 As shown, optionally, a first sliding guide portion 143 is provided on at least one side of the first chain 142 of the first chain belt 14 near the first notch 13, and the first sliding guide portion 143 is used to guide the slider 3 and adjust the mutual position between the first chain 142 of the first chain belt 14 and the second chain 222 of the second chain belt 22. And / or a second chain 222 of the second chain belt 22 is provided on at least one side near the second notch 21, and the second sliding guide portion 223 is used to guide the slider 3 and adjust the mutual position between the first chain 142 of the first chain belt 14 and the second chain 222 of the second chain belt 22.

[0070] Specifically, the first sliding guide portion 143 and the second sliding guide portion 223 can exist separately or together. The first sliding guide portion 143 and / or the second sliding guide portion 223 are located near the first notch 13 and / or the second notch 21. The slider 3 is first pulled into the zipper from the first sliding guide portion 143 and / or the second sliding guide portion 223. Up to this point, since the combined width of the two guide portions is narrower than the normal zipper width, the relative positions of the chain teeth entering the slider 3 can be adjusted here. It can also play a guiding role to adjust the portion of the zipper that smoothly enters the meshing area 32 of the slider 3. Preferably, the first sliding guide portion 143 and the second sliding guide portion 223 are in a gradual manner, that is, they gradually decrease in the direction of the notch.

[0071] like Figure 4 As shown, optionally, the first sliding guide portion 143 is a non-engaging chain tooth, and the height of the non-engaging chain tooth is equal to or lower than half of the height of the chain tooth of the non-first sliding guide portion 143, or the first sliding guide portion 143 is an insertion tube, and the height of the insertion tube is equal to or lower than half of the height of the chain tooth of the non-first sliding guide portion 143. The second sliding guide portion 223 is a non-engaging chain tooth, and the height of the non-engaging chain tooth is equal to or lower than half of the height of the chain tooth of the non-second sliding guide portion 223, or the second sliding guide portion 223 is an insertion tube, and the height of the insertion tube is equal to or lower than half of the height of the chain tooth of the non-second sliding guide portion 223.

[0072] Specifically, the chain teeth and the insert are two specific forms of the first sliding guide part 143 and the second sliding guide part 223. Both of them can be chain teeth or inserts, or one can be a chain tooth and the other can be an insert. Both the height of the chain teeth and the height of the insert are lower than the height of normal chain teeth, that is, the height of the chain teeth of the non-sliding guide part. Non-engaging chain teeth are special chain teeth different from ordinary chain teeth. The non-engaging chain teeth on both sides cannot be directly engaged together, and there will be a gap in the middle.

[0073] Optionally, the detachable bag further includes a closing component installed at the first notch 13 or the second notch 21 for closing the confluence of the first fastener tape 14 or the confluence of the second fastener tape 22 .

[0074] Specifically, one of the first notch 13 and the second notch 21 may be closed so that the two sliders 3 after installation will not fall from the first notch 13 or the second notch 21 .

[0075] like Figure 5 As shown, optionally, the slider 3 includes two front introduction ports 31, an engagement area 32 located at the rear side of the front introduction ports 31, and a rear introduction area 33 located at the rear side of the engagement area 32, wherein the rear introduction area 33 is an extension outward from the engagement area 32, so as to guide the first tooth chain 142 and the second tooth chain 222 into the slider 3 from the rear introduction area 33.

[0076] Specifically, the two front introduction ports 31 can guide the first tooth chain 142 and the second tooth chain 222 respectively. When the first tooth chain 142 and the second tooth chain 222 enter the slider 3 from the front introduction port 31, they enter the meshing area 32 and mesh together. However, in the solution of the present invention, the first tooth chain 142 and the second tooth chain 222 can also enter from the rear side of the slider 3. In order to facilitate their entry, a rear introduction area 33 is set on the rear side. The rear introduction area 33 can be an involute area. The rear introduction area 33 enables both sides of the slider 3 to pull the first tooth chain 142 and the second tooth chain 222 into the slider 3.

[0077] like Figures 6 to 8 As shown, optionally, the sealing device 4 includes a bottom plate 41 and a cover plate 42. The bottom plate 41 includes a lower limit portion 411, a lower groove 412 located inside the lower limit portion 411, and a lower fixing mechanism 413 disposed in the lower groove 412, wherein the lower groove 412 includes a lower opening 4121. The cover plate 42 includes an upper fixing mechanism 421, and the upper fixing mechanism 421 cooperates with the lower fixing mechanism 413 to fix the ends of the first and second fastener belts 14 and 22 that enter the lower groove 412 through the lower opening 4121.

[0078] Specifically, the lower groove 412 can be a recessed portion formed inwardly through one side of the bottom plate 41, and the remaining portions on both sides are the lower limit portions 411. The space of the lower groove 412 portion is sufficient to accommodate the first and second tooth chains 142 and 222. The lower opening 4121 can be located on one side of the lower groove 412, for introducing the first and second tooth chains 142 and 222 into the lower groove 412. A lower fixing mechanism 413 is provided behind the lower opening 4121. Preferably, the lower fixing mechanism 413 is provided in the middle of the lower groove 412.
