Description

Technical Field

[0001] This application relates to the field of packaging boxes, and more specifically to a support structure for stacking packaging boxes. Background Technology

[0002] Packaging boxes are widely used in all aspects of people's production and life. In order to improve the strength of packaging boxes, our company has applied for a base that can make the packaging box have higher strength in the patent "A Packaging Box Base with Flip Buckle" (application number 202220900421.X). This base can effectively fasten to the upper edge of the material board, improve the stress capacity of the material board, increase the stability of the product, and can also be used as a handle, thus improving the product's performance.

[0003] However, as the product is promoted and used, its weight is relatively heavy due to the large number of plastic parts. With the standardization of the market, many markets have set limits on the weight of packaging. If the weight of the packaging box exceeds the limit, it will not be allowed to enter the market for sale.

[0004] In order to better meet market demands while ensuring the strength of the packaging box, our company has further optimized the product. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides a support structure for stackable packaging boxes, which effectively reduces the overall weight of the packaging boxes while still ensuring their strength and ease of stacking, better meeting market demands and further promoting the development and progress of the industry.

[0006] A support structure for stackable packaging boxes includes a crossbar and two uprights symmetrically arranged on the left and right sides of the crossbar.

[0007] Preferably, the column can rotate around the connection point between the crossbar and the column as the center.

[0008] Furthermore, the crossbar is composed of a strip, a slotted block and a column head disposed on the back side of the strip.

[0009] Preferably, the slot block is located in the middle of the back side of the strip, and the slot block has a downward opening slot; there are two columns, which are symmetrically arranged on the left and right sides of the strip, and the columns are perpendicular to the strip.

[0010] Preferably, the diameter of the lower half of the column head is smaller than the diameter of its upper half, and the upper half of the column head is semi-circular; the column head is also provided with an opening that penetrates itself along the axial direction.

[0011] Furthermore, the column consists of a column body, a side plate disposed on the side of the column body, a slot disposed on the upper part of the back of the column body, a positioning head disposed on the top of the column body, a limiting groove disposed on the bottom of the column body, and a rear plate disposed on the side plate and located behind the column body.

[0012] Preferably, a gap is formed between the side plate and the left or right side of the column, and several sloping blocks are provided on the side plate at the entrance of the gap.

[0013] Preferably, the rear retaining plate is perpendicular to the side retaining plate, and a gap is formed between the rear retaining plate and the back of the column.

[0014] Preferably, the bayonet engages with the column head.

[0015] Preferably, the positioning head matches the limiting groove.

[0037] Example 1

[0038] like Figure 1-4 As shown, a support structure for stacked packaging boxes includes a crossbar 100 and two uprights 200 symmetrically arranged on the left and right sides of the crossbar 100.

[0039] The column 200 can rotate around the connection point between the crossbar 100 and the column 200.

[0040] like Figure 5-7 As shown, the crossbar 100 is composed of a strip 101, a slot block 102 and a column head 103 disposed on the back side of the strip 101.

[0041] The slot block 102 is located in the middle of the back side of the strip 101, and the slot block 102 has a downward opening slot; there are two pillars 103, which are symmetrically arranged on the left and right sides of the strip 101, and the pillars 103 are perpendicular to the strip 101.

[0042] The slot block is installed by locking it onto the top of the left and right side walls of the packaging box. Then, the two uprights are rotated to fit and fix it to the front and back of the side walls. A vertical limiting piece can also be installed in the slot block. Matching notches are made on the left and right side walls of the packaging box according to the position of the limiting piece, ensuring that the limiting piece can engage with the notch when the slot block is inserted, thereby further improving the stability of the product.

[0043] The diameter of the lower half of the column head 103 is smaller than the diameter of its upper half, and the upper half of the column head 103 is semi-circular; the column head 103 is also provided with an opening that penetrates itself along the axial direction.

[0044] The distance between the column head and the slot block needs to be adjusted according to the rotation radius of the column to ensure that the column is not blocked by the side wall of the slot block during rotation, thus ensuring smooth product operation. The structure of the column head is existing technology, and its setting and usage methods are well known to those skilled in the art. Those skilled in the art can complete its setting and use without creative effort based on the above description, and will not be elaborated here.

[0045] like Figure 8-10 As shown, the column 200 is composed of a column body 201, a side plate 202 disposed on the side of the column body 201, a slot 205 disposed on the upper part of the back of the column body 201, a positioning head 204 disposed on the top of the column body 201, a limiting groove 207 disposed on the bottom of the column body 201, and a rear plate 203 disposed on the side plate 202 and located behind the column body 201.

[0046] A gap is formed between the side plate 202 and the left or right side of the column 201, and a number of sloping blocks 206 are provided on the side plate 202 at the entrance of the gap.

[0047] In use, the front and rear side walls of the packaging box are inserted through the gap between the side plate and the column. Square holes are provided on the front and rear side walls of the packaging box to allow them to mate with the sloping locking blocks. The sloping structure of the locking blocks facilitates the insertion of the front and rear side walls of the packaging box. After the front and rear side walls are inserted, the straight rear wall of the sloping locking blocks can limit the square holes to prevent the front and rear side walls from sliding outward from the gap.

[0048] The rear card plate 203 is perpendicular to the side card plate 202, and a gap is formed between the rear card plate 203 and the back of the column 201.

[0049] The gap formed between the rear plate and the column can clamp the product against the front and back of the left and right side walls of the packaging box when the column is rotated, further improving the fit between the product and the side walls of the packaging box, thereby improving the product's performance.

[0050] The bayonet 205 is engaged with the column head 103.

[0051] During assembly, simply insert the column head into the bayonet to complete the connection between the crossbar and the column. The installation is simple and convenient, greatly improving the assembly efficiency of the product.

[0052] The positioning head 204 is matched with the limiting groove 207.

[0053] The positioning head and limiting groove can greatly improve the stability of packaging boxes when stacking, and at the same time make the packaging boxes stacked more neatly and beautifully.

[0054] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0055] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this invention, and these solutions all fall within the scope of this invention and its protection. Those skilled in the art should understand that this specification and its accompanying drawings are illustrative and not intended to limit the scope of the claims. The scope of protection of this invention is defined by the claims and their equivalents.
