Description

Technical Field

[0001] This utility model belongs to the field of packaging box technology, and specifically relates to a base for packaging boxes. Background Technology

[0002] In traditional logistics transportation and warehousing, packaging boxes serve as crucial load-bearing tools, and their design and structure directly impact transportation efficiency and cargo safety. While traditional wooden or plastic packaging boxes meet basic needs to some extent, they still have many shortcomings. For example, wooden packaging boxes are heavy, inconvenient to handle, and prone to moisture damage and deformation; plastic packaging boxes, although lightweight, have limited load-bearing capacity and are prone to aging and cracking after prolonged use. Furthermore, these traditional packaging boxes are complex to disassemble and assemble. For instance, a detachable packaging box includes a base, support legs, box body, lid, and corner clips. Since the base is a vital component, if it cannot effectively secure the side panels, displacement during transportation can affect the stability of the packaging box, failing to meet the demands of modern logistics for efficiency and convenience.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] Example 1

[0022] like Figures 1-4As shown, this utility model provides a base for a packaging box, applied to a detachable packaging box, including support legs 2, a box body, a lid, and corner clips. The support legs 2 are fixed to the lower side of the base by welding or bolts, specifically in three groups, symmetrically distributed on both sides and the middle of the bottom of the base. Forklift slots 21 are provided on the support legs 2 for easy forklift handling; multiple side grooves 22 are provided above the forklift slots 21 along the extension direction of the support legs 2 to enhance the bending strength of the side walls of the support legs 2; several transverse grooves 23 are provided on the bottom end face of the support legs 2, penetrating the bottom of the forklift slots 21 to further disperse the stress when the forklift applies force, improving structural stability.

[0023] The base is formed by welding longitudinal frames 11 and transverse frames 12 end to end to form a rectangular frame, within which a steel plate base 13 is embedded. Multiple packaging rings 14 are bolted to the edges of the base 13 for securing goods. Square slots 17 are formed on the inner walls of both the longitudinal frames 11 and transverse frames 12. Multiple sets of locking slots 15 are spaced apart on the inner side of each square slot 17, and square positioning posts 16 are vertically welded to the bottom (e.g., ...). Figure 1 As shown, in other embodiments, the positioning post 16 may also be a cylindrical or frustum structure.

[0024] The housing includes a first side plate and a second side plate connected end to end. Symmetrically welded reverse-shaped C-shaped frames are welded to both sides of the vertical tubes of the first and second side plates. The C-shaped frames of adjacent side plates interlock to form the four corners 2 of the housing. The bottom of the housing has a locking platform that matches the locking slot 15, and a bottom groove that inserts into the positioning post 16. During assembly, the locking platform is inserted into the locking slot 15, and the bottom groove is fitted into the positioning post 16, achieving precise positioning and fixation of the housing to the base.

[0025] The top of the box has a first slot around its four sides, and the second slots are located on the second side panels on both sides of the top. The lid is a rectangular frame structure that covers the top of the box, and its four corners are secured by corner clips inserted into the first slots. The support rod is an adjustable-length metal rod, with both ends inserted into the second slots and corresponding holes on the lid, respectively, to support the lid and enhance overall rigidity. A locking component is installed on the outer side of the first side panel, and the hooks of the locking component cooperate with the buckles on the edge of the lid to further secure the lid.

[0026] Assembly process:

[0027] Fix the support leg 2 to the bottom of the base, and move the base to the designated position through the forklift slot 21;

[0028] Align the mounting plate of the box with the slot 15 of the base, align the bottom slot with the positioning post 16, and press down vertically to insert and fix the box to the base; insert the support rod into the second slot of the box, adjust the length, and connect it to the cover.

[0029] Close the cover, insert the corner clip into the first slot, and fasten the locking components to complete the assembly.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that the positioning column 16 has a frustum-shaped structure, and its conical surface forms a wedge-tight fit with the inner wall of the bottom groove, further enhancing the connection stability between the box and the base.

[0032] Example 3

[0033] In this embodiment, the first and second side panels of the box are made of honeycomb aluminum panels, the horizontal and vertical tubes are hollow square steel, and the C-shaped frame is fixed to both sides of the vertical tube by riveting, which reduces the overall weight while maintaining the structural strength.

[0034] The positioning post 16 can be a square block, a cylinder, or a frustum.

[0035] The base plate 13 is provided with drainage holes.

[0036] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
