Various details of the embodiments of the present disclosure are included to assist in understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, the description below omits the description of well-known functions and structures.

[0026] In the description of the present utility model, it should be noted that the term "including" and its variants mean open inclusion, that is, "including but not limited to". The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, in the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0027] The present utility model provides a quick-fold box, refer to Figures 1 - 3As shown in the figure, it includes a box body, and the box body includes a bottom plate 1, a first side plate 2 and a second side plate 3 that are foldably connected to the four sides of the bottom plate 1. There are two relatively arranged first side plates 2, and there are two relatively arranged second side plates 3. After the two first side plates 2 and the two second side plates 3 are respectively turned inward by 90° along the fourth crease at the connection with the bottom plate 1, they can enclose a box space with the bottom plate 1. A connecting plate 4 is arranged between each adjacent first side plate 2 and second side plate 3. The connecting plate 4 includes a fixed plate 41 close to the first side plate 2 and a movable plate 42 close to the second side plate 3. The fixed plate 41 is fixedly connected to the inner surface of the first side plate 2. A first crease 43 is arranged between the fixed plate 41 and the movable plate 42, and a second crease 44 is arranged between the movable plate 42 and the second side plate 3. As Figure 1 As shown in the figure, it is a planar structure formed by cutting and die-cutting the plates of the box body. During production, the fixed plate 41 is fixedly connected to the inner surface of the first side plate 2, then the box body structure is formed from the planar plate structure, and the box body can be folded into a box state and a flattened state. Reinforcing plates 5 that are foldably connected to the first side plate 2 are arranged on one side of the two first side plates 2 away from the bottom plate 1. When the box body is folded into the box state, the reinforcing plates 5 are stacked on the inner surface of the first side plate 2. The reinforcing plates 5 are stacked on the first side plate 2, which can clamp the movable plate 42 between the first side plate 2 and the reinforcing plates 5, thereby restricting the flipping of the movable plate 42 to form a stable box body, and can also increase the pressure-bearing strength of the first side plate 2 and improve the pressure-bearing capacity of the box body.

[0028] Reference Figures 2 - 4 As shown in the figure, the process of folding the box body from the box state to the flattened state is as follows: After pulling the two reinforcing plates 5 upward to flip and release the movable plate 42, press the reinforcing plates 5 against the upper edge of the movable plate 42 and the first side plate 2, and push the first side plate 2 to flip 90° around the bottom plate 1 to flatten the first side plate 2. At this time, the movable plate 42 flips along the first crease 43, and the movable plate 42 and the second side plate 3 are flattened. The two reinforcing plates 5 respectively cover the movable plate 42 and the first side plate 2 at both ends, and the box body as a whole forms a flattened state of a rectangular flat plate, with a regular and flat shape, convenient for stacking and storage, small in occupied space, and convenient for recycling and transportation when the box body is recycled. The process of folding the box body from the flattened state into the box state is as follows: Lift the two reinforcing plates 5 upward, and at the same time push the first side plate 2 inward to form a box space, and then turn the reinforcing plates 5 inward so that the reinforcing plates 5 are stacked on the inner surface of the first side plate 2. The box body of this folding box adopts an inward-pushing folding structure, which can be quickly folded into a box state and a flattened state, with convenient and fast operation and time-saving.

[0029] It can be understood that the term "inner surface" refers to the surface facing the box space in the plane structure diagram of the box body as the inner surface, and the "outer surface" refers to the surface facing away from the box space in the plane structure diagram of the box body as the outer surface. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] In one embodiment, the fixed plate 41 is connected to the first side plate 2, and a third fold is provided at the connection, and the inner surface of the fixed plate 41 is fixedly connected to the inner surface of the first side plate 2. In this embodiment, when the fixed plate 41 is folded and fixed to the first side plate 2 by a planar structure, the fixed plate 41 is turned inward 180° around the third fold, and the inner surface of the fixed plate 41 is fixedly attached to the inner surface of the first side plate 2. When folded into a box state, the movable plate 42 is folded along the first fold 43, and its outer surface is attached to the outer surface of the fixed plate 41.

[0031] In one embodiment, a first notch is provided between the fixed plate 41 and the first side plate 2, and the outer surface of the fixed plate 41 is fixedly connected to the inner surface of the first side plate 2. In this embodiment, when the fixed plate 41 is folded and fixed to the first side plate 2 by a planar structure, the connecting plate 4 turns inward 90° around the second fold 44 at the connection between the connecting plate 4 and the second side plate 3, and after the first side plate 2 and the second side plate 3 turn inward 90° along the fourth fold at the connection with the bottom plate 1, the outer surfaces of the fixed plate 41 and the movable plate 42 are both attached to the inner surface of the first side plate 2, and then the fixed plate 41 is fixed to the first side plate 2. In this way, the entire connecting plate 4 is attached to the first side plate 2, which can further enhance the bearing strength of the first side plate 2 in the horizontal and vertical directions. After being folded into a box body, the strength is high, which not only has a strong bearing capacity for the parts placed in the box body, but also has a higher bearing strength for the folding box itself when the folding box is stacked, and the transportation process is safer.

[0032] Generally, the box body of a folding box is set to be a rectangular parallelepiped, and the length and width of the rectangular parallelepiped are respectively the length of the connection between the first side panel 2 and the bottom panel 1 and the length of the connection between the second side panel 3 and the bottom panel 1. When the lengths of the first side panel 2 and the second side panel 3 are the same, either side panel can be set to be the first side panel 2. When the lengths of the first side panel 2 and the second side panel 3 are different, the side panel with the longer length can be set to the first side panel 2. This can increase the strength of the long side of the box body, so that the strength of the box body is higher after being folded into a box state.

[0033] When the box body is folded into the box state and the flattened state, in order to prevent the reinforcing plate 5 from warping after folding, the reinforcing plate 5 can be detachably fixed to the superposed plates. Specifically, a first magic tape can be provided on the inner surface of the reinforcing plate 5, and a second magic tape adapted to the first magic tape can be provided on the outer surface of the movable plate 42. When the box body is folded into the flattened state, the inner surface of the reinforcing plate 5 is attached to the outer surface of the movable plate 42, and the first magic tape is adhered to the second magic tape to fixedly connect the reinforcing plate 5 and the movable plate 42, preventing the reinforcing plate 5 from folding and warping, making it flatter and easier to stack during storage and stacking. When the fixing plate 41 is connected to the first side plate 2 and the inner surface of the fixing plate 41 is fixedly connected to the inner surface of the first side plate 2, when the box body is pushed inward and folded into the box state, the outer surface of the movable plate 42 is attached to the outer surface of the fixing plate 41, and the inner surface of the reinforcing plate 5 is attached to the outer surface of the movable plate 42. A third magic tape adapted to the first magic tape can be provided on the inner surface of the movable plate 42. When the box body is folded into the box state, the first magic tape is adhered to the third magic tape, and the reinforcing plate 5 can be fixed to the movable plate 42. When a first notch is provided between the fixing plate 41 and the first side plate 2 and the outer surface of the fixing plate 41 is fixedly connected to the inner surface of the first side plate 2, when the box body is pushed inward and folded into the box state, the inner surface of the fixing plate 41 is attached to the inner surface of the reinforcing plate 5. A third magic tape adapted to the first magic tape can be provided on the inner surface of the fixing plate 41. When the box body is folded into the box state, the first magic tape is adhered to the third magic tape, and the reinforcing plate 5 can be fixed to the fixing plate 41. The reinforcing plate 5 can be conveniently fixed through the magic tape, keeping the box state and the flattened state stable.

[0034] Reference Figure 1 and Figure 2 As shown, when the box body is folded into the box state, the edge of the box opening is the edge of the second side plate 3 and the fifth crease at the connection between the first side plate 2 and the reinforcing plate 5. In order to prevent scratching the operator and enhance protection, the edge of the second side plate 3 away from the bottom plate 1 is set as a rounded edge, and the fifth crease at the connection between the first side plate 2 and the reinforcing plate 5 itself is a smooth structure, so that the opening edge of the box can be made smooth, improving the safety of operation. Reference Figure 1 and Figure 3 As shown, when the box body is folded into the flattened storage state, the edges of the second side plate 3, the movable plate 42, and the reinforcing plate 5 are exposed. The inner surface of the reinforcing plate 5 is attached to the outer surface of the movable plate 42. When operating, the operator needs to grasp the edge of the reinforcing plate 5 to push and pull the reinforcing plate 5. Therefore, for operation safety, the edges of the movable plate 42 away from the bottom plate 1 and the reinforcing plate 5 away from the bottom plate 1 are set as rounded edges.

[0035] After the reinforcing plate 5 is folded, it is stacked with the first side plate 2, which can improve the pressure-bearing strength of the first side plate 2, cover the fixing plate 41 and the movable plate 42, and the width L1 of the reinforcing plate 5 can be set to 50%-100% of the width L2 of the first side plate 2. For example, the width L1 of the reinforcing plate 5 can be set to 50%, 60%, 70%, 80%, 90%, 100% of the width L2 of the first side plate 2, etc. Preferably, the width L1 of the reinforcing plate 5 can be made equal to the width L2 of the first side plate 2, so that the reinforcing plate 5 extends to the bottom of the box body after folding, further increasing the pressure-bearing strength of the first side plate 2, improving the shielding effect, making the box body more beautiful, and can also strengthen the protection of parts and prevent the edges of the plates from scratching the parts.

[0036] In one embodiment, a handle 51 is provided at the edge of the reinforcing plate 5 away from the first side plate 2. The handle 51 is provided in the middle of the edge of the reinforcing plate 5 and can be set in a notch shape or in a pull ring shape to facilitate pushing and pulling the reinforcing plate 5.

[0037] The material of the box body can be made of PP hollow board, which is not easily damaged, can be recycled many times, and has good economy. Moreover, it is convenient to process creases on the board through a knife die. Compared with using rotating combination fittings such as plastics or metals to realize the folding of the box body, the PP hollow board is thinner, flatter and more convenient for recycling and stacking after being folded into a flattened state. Preferably, the hollow board uses an S-shaped hollow board. Compared with a straight corrugated hollow board material, using an S-shaped hollow board has higher strength, better foldability, and higher load-bearing capacity after being folded into a box body state, and can achieve the lightweight of the box body weight when meeting the strength requirements. The appropriate thickness of the hollow board can be selected according to the needs of carrying parts. Preferably, the thickness of the hollow board is set to 2-8 mm. For example, the thickness of the hollow board can be set to 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, etc.

[0038] According to the material of the box body, the fixing plate 41 and the first side plate 2 can be fixed by bonding, welding, riveting, etc. When the material of the box body is set to PP hollow board, preferably, the fixing plate 41 and the first side plate 2 are fixed by ultrasonic welding or riveting to improve the connection strength between the fixing plate 41 and the first side plate 2 and make it more durable. Multiple fixing points can be set between the fixing plate 41 and the first side plate 2. Preferably, two or three fixing points can be set. One end of the fixing plate 41 close to the first side plate 2 is wider, and two fixing points can be set, and one fixing point can also be set at the other end, so that the fixing plate 41 is firmly fixed to the first side plate 2.

[0039] The folding box further includes a box cover. When the box body is folded into a box state, the box cover is buckled on the opening of the box. The box body and the box cover adopt a split design, which is convenient for removing the box cover and taking out the parts.

[0040] The box body of the folding box adopts an inward-pushing folding structure design, which can be quickly folded into a box state and a flattened state, greatly improving the convenience of the box folding operation and saving working hours. It can also be recycled and reused to save costs. When the box body is folded into a flattened state, it has a regular shape and a small volume, effectively saving space occupancy and facilitating stacking and transportation. When the box body is folded into a box state, by stacking the reinforcing plate 5 on the inner surface of the first side plate 2, the strength of the box can be improved, meeting the needs of most packaging markets. For example, it can meet the packaging and transportation strength requirements of fresh food, auto parts, etc., and has good economy.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
