Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of packaging boxes, and in particular relates to a retractable box. Background Art
[0002] When transporting items, you need to use packaging boxes to pack them. In order to ensure that the items do not collide during transportation, general packaging boxes are customized according to the size and shape of the items. When customers receive the items, the packaging boxes used to pack relatively flat items are generally of no value for reuse and will be thrown away directly or sold as waste paper, and cannot be reused. Utility Model Content
[0003] The utility model aims to provide a scalable box, which can reuse a packaging box for packaging relatively flat articles, so that the packaging box becomes a usable storage box and exerts its value.
[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a retractable box, comprising a bottom box, an intermediate body and an upper cover, wherein the bottom box is provided with a placement cavity, the intermediate body is arranged in the placement cavity of the bottom box, and the upper cover is used to cover the upper side of the intermediate body; the intermediate body is a rectangular parallelepiped structure, and the intermediate body comprises a main box body and four box plates, the four box plates are respectively fixed to the four sides of the lower side of the main box body and can be folded to the bottom of the main box body, and the lengths of the four box plates are respectively the same as the length or width of the intermediate body; the inner side of the placement cavity matches the outer side of the main box body or the outer sides of the four box plates after unfolding.
[0005] Furthermore, a covering cavity is provided in the upper cover, and the inner side of the covering cavity matches the outer side of the intermediate body.
[0006] Furthermore, at least one of the box plates is provided with an inserting tongue at a connection position with the main box body, and a socket is provided on the bottom box at a position corresponding to the inserting tongue.
[0007] Furthermore, a first fold line is provided at the position where the four box plates are connected to the main box body.
[0008] Furthermore, a second fold line is provided on the box plate, and the second fold line is parallel to the first fold line.
[0009] The working principle of this technical solution is: when transporting items, fold the four box plates inward along the first fold line. If the height of the box plate is too high, fold the box plate by setting a second fold line. Then insert the tongue on the box plate into the socket on the bottom box. Place the item in the intermediate body, and then close the upper cover on the intermediate body. After taking out the item, the tongue can be taken out of the socket, pull the main box body, and pull it upward, and press the four box plates outward so that the four folded box plates are pulled to a vertical state, the height of the entire intermediate body is increased, and the accommodating space becomes larger. The inner wall of the placement cavity is against the outer side of the four box plates to achieve their positioning and fixation.
[0010] The beneficial effects of this technical solution are:
[0011] ① After the box board of this technical solution is folded, the storage space of the middle body is small, and relatively flat items can be packaged. After the box board is pulled up, the storage space of the middle body is increased, and it can be used as a storage box, and the packaging box can be reused to realize its value.
[0012] ② The technical solution provides a tongue to fix the intermediate body and the bottom box.
[0013] ③ The technical solution sets a second folding line, and folds the box plate with a higher height (higher than the length or width of the main box body on the corresponding side). BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is further described in detail through specific implementation methods:
[0018] The reference numerals in the drawings of the specification include: base box 1, intermediate body 2, upper cover 3, placement cavity 4, insertion tongue 5, main box body 6, box plate 7, first inflection line 8, second inflection line 9, and cover cavity 10.
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The embodiment is basically as shown in the attached Figure 1-3 As shown: a retractable box, comprising a bottom box 1, an intermediate body 2 and an upper cover 3, wherein a placement cavity 4 is provided in the bottom box 1, and the intermediate body 2 is provided in the placement cavity 4 of the bottom box 1. The intermediate body 2 is a rectangular parallelepiped structure, and the intermediate body 2 comprises a main box body 6 and four box plates 7, wherein the four box plates 7 are respectively fixed to the four sides of the lower side of the main box body 6 and can be folded to the bottom of the main box body 6, and the lengths of the four box plates 7 are respectively the same as the length or width of the intermediate body 2. The inner side of the placement cavity 4 matches the outer side of the main box body 6 or the outer side of the four box plates 7 after unfolding. The upper cover 3 is used to cover the upper side of the intermediate body 2, and a covering cavity 10 is provided in the upper cover 3, wherein the inner side of the covering cavity 10 matches the outer side of the intermediate body 2, and the upper cover 3 and the intermediate body 2 are covered and fixed by friction.
[0021] At least one box plate 7 is provided with an inserting tongue 5 at the connection position with the main box body 6, and a socket is provided at the position corresponding to the inserting tongue 5 on the bottom box 1. In the technical solution, the inserting tongue 5 is provided on the two opposite box plates 7. The first inflection line 8 is provided at the connection position of the four box plates 7 with the main box body 6. When the height of the box plate 7 is relatively high, a second inflection line 9 is provided on the box plate 7, and the second inflection line 9 is parallel to the first inflection line 8.
[0022] The specific implementation process is as follows:
[0023] When transporting items, fold the four box plates 7 inward along the first fold line 8. If the height of the box plate 7 is too high, fold the box plate 7 through the second fold line 9. Then insert the tongue 5 on the box plate 7 into the socket on the bottom box 1. Place the items in the intermediate body 2, and then cover the upper cover 3 on the intermediate body 2. After taking out the items, the tongue 5 can be taken out of the socket, the main box body 6 can be pulled and pulled upward, and the four box plates 7 can be pressed outward, so that the four folded box plates 7 are pulled to a vertical state, the height of the entire intermediate body 2 is increased, and the accommodating space becomes larger. The inner wall of the placement cavity 4 is against the outer side of the four box plates 7 to achieve their positioning and fixation.
