Description

Technical Field

[0001] The present application relates to the technical field of packaging structures, and in particular to a stackable anti-displacement packaging box. Background Art

[0002] Wooden packing boxes are a common packaging container. Compared with paper packing boxes, wooden packing boxes have higher structural strength. Even when containing heavier items, such as metal mechanical parts, they can maintain good shape stability. Moreover, wooden packing boxes can be stacked. However, after containing heavier items, the number of stacking layers of wooden packing boxes is very limited.

[0003] On the other hand, although the coefficient of friction between wooden materials is relatively high, during transportation, the boxes closer to the top will move more relative to the boxes at the bottom. Therefore, the higher the number of stacked layers, the greater the risk of tipping. Summary of the invention

[0004] The purpose of the present application is to provide a packaging box that will not shift even when multiple layers are stacked.

[0005] To achieve the above objectives, the present application provides a stackable anti-displacement packaging box: comprising a base, a plurality of side sealing plates fixedly connected to the upper surface of the base, side frames fixedly connected between the side sealing plates, the bottom surface of the side frame being higher than the lower surface of the base, the top surface of the side frame being higher than the top surface of the side sealing plate, the top of the side frame being suitable for plugging and cooperating with the base of another stackable anti-displacement packaging box above, an upper cover being suitable for being arranged above the side sealing plate, and the upper cover being also suitable for plugging and cooperating with the side frame, thereby forming a complete packaging box structure.

[0006] Preferably, the side frame includes an inner embedded panel, the side of the inner embedded panel has an outer plate, the inner embedded panel and the outer plate have equal lengths in the vertical direction, the inner embedded panel is located at the center of the side of the outer plate, and the side sealing plate is fixedly connected between the side of the inner embedded panel and the outer plate to achieve a perfect fit.

[0007] Preferably, the number of the side sealing plates is four, and the two side sealing plates fixedly connected to the same side frame are perpendicular to each other and form a regular quadrangular prism.

[0008] As a preferred embodiment, the side sealing plate is fixedly connected to the inner panel by means of a transverse nail, and the transverse nail passes through the inner panel and then is inserted into another side sealing plate in the extension direction, thereby reducing the number of nails used and simplifying the fixing operation.

[0009] As a preferred embodiment, the base is fixedly connected to each of the side sealing plates by longitudinal nails to ensure the connection stability of the base.

[0010] As a preferred embodiment, the base is provided with a connected inner slot and outer slot, both of which pass through the upper and lower surfaces of the base, the inner slot is suitable for plugging with the inner embedded panel, and the outer slot is suitable for plugging with the outer attached panel, which can effectively prevent movement between the upper and lower packaging boxes.

[0011] As a preferred embodiment, the upper cover is provided with a connected inner slide groove and an outer slide groove, both of which pass through the upper and lower surfaces of the upper cover, the inner slide groove is suitable for plugging with the inner embedded panel, and the outer slide groove is suitable for plugging with the outer panel, so as to ensure the stability of the upper cover after configuration.

[0012] Preferably, the bottom surface of the side frame is flush with the upper surface of the base, and the height of the portion of the side frame that exceeds the top surface of the side sealing plate is the sum of the thicknesses of the upper cover and the base, so that the upper cover and the base are interchangeable.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] (1) By providing a side frame and a base structure that can be plugged into each other, the stacked packaging boxes are restrained from each other, effectively suppressing the movement between the upper and lower packaging boxes during transportation, and preventing horizontal misalignment due to displacement, thereby effectively reducing the risk of stacked packaging boxes tipping over;

[0015] (2) By designing a T-shaped side frame, not only the load capacity of the packaging box is improved, but also the limit between the upper and lower packaging boxes is more stable. At the same time, the number of long nails used can be effectively reduced, making the assembly operation of the entire packaging box simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] The terms "including" and "having" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0029] like Figure 1-8The stackable anti-displacement packaging box shown includes a square base 2, which is usually made of a wooden board with a certain thickness and has good strength and lightness. A number of side sealing panels 3 are fixedly connected to the upper surface of the base 2. Usually, there are four side sealing panels 3, which can form a regular quadrangular prism, allowing the entire packaging box to make better use of space and improve storage and transportation efficiency. The side sealing panels 3 are also made of wooden boards that are easy to nail into. The base 2 is fixedly connected to each side sealing panel 3 by longitudinal nails 203 to ensure that the position of the side sealing panels 3 on the base 2 is stable.

[0030] The side sealing plates 3 are fixedly connected with the side frames 4, so the two side sealing plates 3 fixedly connected with the same side frame 4 are perpendicular to each other. The specific structure of the side frame 4 includes an inner panel 401, and the side of the inner panel 401 has an outer panel 402. The inner panel 401 and the outer panel 402 are an integrated structure, which are planed from wood with better toughness. The inner panel 401 and the outer panel 402 have the same length in the vertical direction, which is convenient for processing and forming. The inner panel 401 is located at the center of the side of the outer panel 402. The width of the outer panel 402 in the horizontal direction is obviously wider than that of the inner panel 401, so that the cross-section of the side frame 4 forms a T-shape. Usually, the width of the outer panel 402 is the width of the inner panel 401. 1, the side sealing plate 3 is fixedly connected between the side surfaces of the inner panel 401 and the outer panel 402. Since the thickness of the inner panel 401 relative to the outer panel 402 is equal to the thickness of the side sealing plate 3, after the side sealing plate 3 is fixed to the side frame 4, the inner side surface of the side sealing plate 3 will remain flush with the inner panel 401, while the outer panel 402 is located on the outer side of the side sealing plate 3. The side sealing plate 3 is fixedly connected to the inner panel 401 by the cross nail 301, and the cross nail 301 will be inserted into another side sealing plate 3 along its own length direction after passing through the inner panel 401, so that two adjacent and mutually perpendicular side sealing plates 3 are connected together, reducing the number of nails used, and the operation is less and more convenient during installation.

[0031] The bottom surface of the side frame 4 is higher than the lower surface of the base 2, and the top surface of the side frame 4 is higher than the top surface of the side sealing plate 3. In this embodiment, the bottom surface of the side frame 4 will be flush with the upper surface of the base 2, and the height of the side frame 4 that exceeds the top surface of the side sealing plate 3 is the sum of the thicknesses of the upper cover 1 and the base 2. Because the thickness of the upper cover 1 is usually the same as the thickness of the base 2, the height of the side frame 4 that exceeds the top surface of the upper cover 1 is twice the thickness of the base 2.

[0032] The top of the side frame 4 can be plugged into and matched with the base 2 of another stackable anti-displacement packaging box above, which can effectively suppress the relative movement of the stacked packaging boxes. In order to achieve this plug-in connection, a connected inner slot 201 and outer slot 202 are opened on the base 2. The inner slot 201 and the outer slot 202 both pass through the upper and lower surfaces of the base 2, also forming a T-shape, with the inner slot 201 on the inside and the outer slot 202 on the outside, and the outer slot 202 passes through the outer side of the base 2, which makes it convenient for staff to observe whether the base 2 and the side frame 4 below are plugged into place, the inner slot 201 is just plugged into the inner embedded plate 401, and the outer slot 202 is just plugged into the outer plate 402. The T-shaped matching structure has good stability.

[0033] An upper cover 1 can be provided above the side sealing plate 3 to cover the upper open end of the topmost packing box in the stack. Therefore, when there is another packing box above the packing box, the upper cover 1 may not be provided on the packing box below, because the base 2 of the packing box above can serve as the upper cover 1 to produce dustproof and shielding effects. This stacking method can effectively reduce the overall weight of the stacked packing boxes, reduce the load on the side frame 4, and reduce the burden during transportation. Of course, in order to ensure the stability of the upper cover 1 after installation, the upper cover 1 will also be The side frame 4 is plug-in compatible, and the upper cover 1 is provided with a connected inner slide groove 101 and an outer slide groove 102, which also form a T-shape. The inner slide groove 101 and the outer slide groove 102 both pass through the upper and lower surfaces of the upper cover 1 for the side frame 4 to pass through. The inner slide groove 101 is used to be plugged with the inner embedded panel 401, and the outer slide groove 102 is used to be plugged with the outer panel 402. The T-shaped interlocking structure at the four corners of the upper cover 1 enables the wooden or plastic upper cover 1 to stay stably on the opening of the packaging box and play its role without the use of nails.

[0034] Assembly method: First, fix the four side sealing panels 3 to the side frames 4 through transverse nails 301 to form a regular quadrangular prism. At this time, the side sealing panels 3 are flush with the bottom surfaces of the side frames 4; then use longitudinal nails 203 to fix the base 2 to the bottom surfaces of all the side sealing panels 3. At this time, the inner slot 201 and the outer slot 202 are aligned with the bottom surfaces of the side frames 4, so that the items to be packaged can be placed in the cavity surrounded by the four side sealing panels 3. Finally, the upper cover 1 is inserted into the four side frames 4 and buckled on top of all the side sealing panels 3 to complete the packaging; continue to stack another packaging box upwards, so that the four side frames 4 below are inserted into the base 2 of the upper packaging box, which can effectively improve the stability of the packaging box after stacking. During transportation, the upper packaging box will not move relative to the lower packaging box.
