Description

Technical Field

[0001] The present application relates to the technical field of storage boxes, and in particular to a storage box with adjustable size. Background Art

[0002] Storage boxes are used to organize and sort out idle items in daily life. According to the materials they are made of, they can be divided into plastic storage boxes, wooden storage boxes or canvas storage boxes. Plastic storage boxes and wooden storage boxes are usually fixed structures. When there are fewer idle items in life, they cannot be folded when they are not needed. Although canvas storage boxes can be folded, there is no retractable fixed frame inside them. They are just simple fiber cloth bags. The overall design is simple. After folding for a long time, the box will easily deform, affecting its reuse. At the same time, as today's social life has entered the Internet era, the prevalence of online shopping has led to a large increase in logistics and express delivery, and the use of packaging storage boxes for logistics has also increased accordingly. Traditional logistics packaging storage boxes are mass-produced with fixed specifications. However, when the general public uses them for actual storage, the sizes of different storage items are not fixed, and the storage items often do not match the storage boxes. This is not conducive to the smooth packaging of storage items and the safety of items during transportation, and it will also cause a large amount of unnecessary waste of box materials.

[0120] Embodiment 15:

[0121] like Figure 27-31 As shown, this embodiment is an embodiment of a special hinge assembly for the structure of the storage box with adjustable size described in Embodiment 3. The difference between this embodiment and Embodiment 3 is that, in order to ensure that the flipping between the side walls of the storage box and between the side walls and the bottom plate is more stable, a hinge assembly 4 is provided between the lower part of the two groups of two-way retractable assembly panels 1-1 of the first folding assembly 3-3-1 and the bottom plate 3; and a hinge assembly 4 is provided between the lower part of the two groups of two-way retractable assembly panels 1-1 of the second folding assembly 3-3-2 and the upper part of the vertical folding avoidance plate 3-321;

[0122] The hinge assembly 4 includes: a first outer rotating plate 4-1, a second outer rotating plate 4-2, an arc-shaped elastic connecting member 4-3, a first inner rotating plate 4-4, a second inner rotating plate 4-5 and a hinge 4-6;

[0123] The first outer rotating plate 4-1 and the second outer rotating plate 4-2 are fixedly connected by an arc-shaped elastic connecting member 4-3, and the three can also be made into an integrated connection structure. The first inner rotating plate 4-4 and the second inner rotating plate 4-5 are hinged to each other by a hinge 4-6;

[0124] The first inner rotating plate 4-4 is correspondingly arranged on the inner side of the first outer rotating plate 4-1, and a first slide rail 4-61 is arranged on one side close to the arc-shaped elastic connecting member 4-3 between the first inner rotating plate 4-4 and the first outer rotating plate 4-1, and a first slider 4-62 slidably matched with the first slide rail 4-61 is arranged on the other side, wherein the sliding direction of the first inner rotating plate 4-4 and the first outer rotating plate 4-1 is perpendicular to the rotation direction between the first inner rotating plate 4-4 and the second inner rotating plate 4-5;

[0125] The second inner rotating plate 4-5 is correspondingly arranged on the inner side of the second outer rotating plate 4-2, and a second slide rail 4-71 is provided on one side close to the arc-shaped elastic connecting member 4-3 between the second inner rotating plate 4-5 and the second outer rotating plate 4-2, and a second slider 4-72 slidably matched with the second slide rail 4-71 is provided on the other side, wherein the sliding direction of the second inner rotating plate 4-5 and the second outer rotating plate 4-2 is perpendicular to the rotation direction between the first inner rotating plate 4-4 and the second inner rotating plate 4-5;

[0126] In this embodiment, the first outer rotating plate 4-1 can be fixedly arranged on the first lateral corrugated plate 1-11 of the bidirectionally retractable component plate 1-1, or the first outer rotating plate 4-1 and the first lateral corrugated plate 1-11 can be made into an integrated structure, or the first lateral corrugated plate 1-11 can be directly used as the first outer rotating plate 4-1. Similarly, the second outer rotating plate 4-2 can be fixedly arranged on the bottom plate 3 or the vertical folding avoidance plate 3-321, or the second outer rotating plate 4-2 and the bottom plate 3 or the vertical folding avoidance plate 3-321 can be made into an integrated structure, or the bottom plate 3 or the vertical folding avoidance plate 3-321 can be directly used as the second outer rotating plate 4-2.

[0127] At the same time, the first slide rail 4-61 and the second slide rail 4-71 can be independently arranged between the first lateral corrugated plate 1-11 and the second lateral corrugated plate 1-12 of the bidirectional retractable component plate 1-1, or can be directly replaced and used as a sliding structure between the first lateral corrugated plate 1-11 and the second lateral corrugated plate 1-12.

[0128] Embodiment 16:

[0129] like Figure 32-33 As shown, this embodiment is another embodiment of the hinge assembly described in the present application. The difference between it and the hinge assembly in the previous embodiment is that the installation position of the hinge 4-6 between the first inner rotating plate 4-4 and the second inner rotating plate 4-5 is different. In this embodiment, it is installed on the other side of the first inner rotating plate 4-4 and the second inner rotating plate 4-5, and the rest of the structure is the same as the previous embodiment.

[0130] At the same time, the various structures of the bidirectional retractable component board 1-1 used in the above-mentioned embodiments of the present application can also be used to arbitrarily replace the use of various side panels or bottom panels, which is also the technical solution that the present application wants to protect, and its structure will not be repeated here.

[0131] In the present application, the advantage of adopting the above-mentioned hinge assembly 4 structure is that due to the sliding structure composed of the first slide rail 4-61 and the first slider 4-62, the second slide rail 4-71 and the second slider 4-72, the first outer rotating plate 4-1 and the second outer rotating plate 4-2 can freely extend and slide with the first inner rotating plate 4-4 and the second inner rotating plate 4-5 regardless of whether they are in a folded or unfolded state, and the first slide rail 4-61 and the second slide rail 4-71 play a limiting role. Combined with the above-mentioned adjustment of the displacement that may occur between the inner and outer two-layer plates during the folding process by the arc-shaped elastic connecting member 4-3, it is ensured that the folding direction and the sliding direction are always perpendicular to each other, which greatly improves the stability of the folding structure between the side wall and the bottom plate and between the side walls of the present application, and can ensure that the edge positions of the inner and outer double-layer plates between the side walls can be aligned at any time in the open state or in the folded state without interference, so that each side wall and the bottom plate can be smoothly pushed and pulled to achieve extension and retraction regardless of whether they are in the open state or in the folded state. At the same time, in order to achieve the above-mentioned expansion and contraction more smoothly, when the edge positions of each side wall and the bottom plate and the inner and outer double-layer plates between the side walls are hinged to each other, the best connection method is to set a hinge structure between the inner and outer plates that are close to each other, and between the outer and inner plates.

[0132] In the description of this application, the term "hinge" is only used to describe the connection relationship between objects. Therefore, the characteristics defined as "hinge" can explicitly or implicitly include various embodiments such as crease hinge, hinge hinge, hinge hinge, etc.

[0133] In addition, it should be noted that the accompanying drawings corresponding to the corrugated plates mentioned in the embodiments illustrate a structure with a wavy cross-section. It is easy for those skilled in the art to think of modifying the shape of the waves into square, V-shape, trapezoid or a combination of these shapes, which should be included in the protection scope of the present application. In addition, with regard to the sliding sleeve structure of the corrugated plates, those skilled in the art should be able to understand that appropriate damping should be set therebetween so that the two corrugated plates can slide against each other and maintain a certain friction force in a certain position to form a locking effect, thereby maintaining a certain spatial shape and size of the box.

[0134] Although the present application uses specific embodiments and their alternatives to illustrate and explain the present application, it should be understood that various changes and modifications can be implemented as long as they do not deviate from the spirit and scope of the present application. In the above-mentioned embodiments, unless otherwise clearly specified and limited, the terms "connection", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, the orientation or position relationship indicated by the terms "up and down", "left and right" and the like are based on the orientation or position relationship shown in the drawings, which is only for the convenience of description and simplified description, and does not indicate or imply a specific orientation.

[0135] Therefore, it should be understood that the present application is not limited in any sense except by the appended claims and their equivalents.
