Description

Technical Field

[0001] This utility model relates to a cable packaging box, specifically a cardboard structure that is folded to form a cable pull-out box. Background Technology

[0002] With the rapid development of technology, cables, including electrical cables and optical cables, are now widely used in various industries. Cables are typically wound on spools and then placed in cable packaging boxes for storage and transportation. (Cable packaging boxes) Figure 4 As shown, while ensuring the safety of the cable from moisture, it is also required that the cable can be quickly pulled out of the box directly through the outlet 10-2 (at this time, the I-beam rotates in the packaging box, thereby sending the unwound cable out of the packaging box) to meet the need for convenient and fast cable installation. Therefore, conventional cable packaging box materials require high mechanical strength, which increases the manufacturing cost of cable packaging boxes; and since cable packaging boxes are mostly used for single purposes, it will also cause resource waste.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] The terms "height," "width," "left," and "right" used in this article refer to... Figure 1 Based on.

[0028] Example 1

[0029] Figure 1 The cardboard structure shown for folding into a cable drawer box includes a flat packaging box sheet. The packaging box sheet comprises a right side 11, a top side 14, a left side 17, and a bottom side 20, which are sequentially connected to form four sides of a rectangle. The right side 11 and left side 17 are at the same height, and the top side 14 and bottom side 20 are at the same height. Folding lines (formed by machine stamping) are provided between these four sides. Adjacent sides are folded 90 degrees to form a drawer box. Figure 2 The state shown.

[0030] The left edge of the right side 11 is a fold line, connecting to the front side 10 with the cable outlet hole 10-2. The left side of the front side is also connected to the left folded edge 2 via a fold line. The right edge is also a fold line, connecting to the back side 12. The right side of the back side is also connected to the right folded edge 3 via a fold line. The bottom edge is also a fold line, connecting to the bottom folded edge 1. The three folded edges are connected to the corresponding surfaces via fold lines. The front side 10 and the back side 12 are at the same height. The left edge of the top surface 14 is connected to the upper half of the front padding layer 13 via a fold line, and the right edge is connected to the upper half of the back padding layer 15 via a fold line. The left edge of the left side surface 17 is connected to the front middle layer 16, which has a central cable outlet 16-2, via a fold line, and the right edge is connected to the back middle layer 18 via a fold line. The left and right sides are also connected to strip-shaped inserts 17-1 corresponding to the left folded edge 2 and the right folded edge 3, respectively (the figure shows two vertically arranged strip-shaped inserts connected to the left and right sides). These strip-shaped inserts are located on the right edge of the front middle layer and the left edge of the back middle layer, and are centered in the height direction. When folded, the left folded edge 2 of the front and the right folded edge 3 of the back can be inserted into the strip-shaped inserts 17-1 on the left and right sides of the left side surface. The left and right sides of the bottom surface are also connected to the front lower half padding layer 19-1 and the back lower half padding layer 21 via fold lines. The width of the upper half pad 13 on the front side and the width of the lower half pad 19-1 on the front side are both half the height of the front side, and the width of the upper half pad 15 on the back side and the width of the lower half pad 21 on the back side are both half the height of the back side.

[0031] The front and back sides are also provided with corresponding gripper holes 10-1. The shape of the gripper holes can be selected and determined as needed. The gripper hole shown in the figure is a horizontally arranged oval shape, and the cut-off part is only the lower straight section and the left and right arc sections (the upper straight section of the oval is a fold line). When in use, the oval part can be folded into the box along the upper straight section of the oval to block the cut surface of the other cardboard and improve the feel when handling the cable pull box.

[0032] The upper half of the front pad and the upper half of the back pad are each provided with an opening 13-1 of the same shape and corresponding to the gripper hole; the middle layer of the front and the middle layer of the back are each provided with a through hole 16-3 of the same shape and corresponding to the gripper hole; the positions of the opening 13-1 and the through hole 16-3 are exactly aligned with the gripper hole. The left edge of the upper half of the front pad and the left edge of the upper half of the back pad are aligned; and a semi-circular upper half hole 13-2 is provided on the left edge of the upper half of the front pad, and a semi-circular lower half hole 19-1 is provided on the left edge of the upper half of the back pad. After folding 90 degrees, the upper half of the front pad and the upper half of the back pad are aligned vertically and their total height is the same as the height of the front pad (after folding 90 degrees, the width of the upper half of the front pad and the width of the upper half of the back pad become the actual height), and the upper half hole 13-2 and the lower half hole 19-1 are also perfectly joined to form a complete hole corresponding to the position of the cable outlet.

[0033] Furthermore, several latches 4 are formed on the left and right sides of the left side face 17; these latches extend to the left and right respectively and cross the left and right edges of the left side face, and then extend to the middle layer of the front and back sides respectively. During manufacturing, the latches can be formed simply by punching U-shaped cuts in the same piece of cardboard with a knife.

[0034] Correspondingly, on the left folded edge 2 connected to the left side edge of the front 10 and the right folded edge connected to the right side edge of the back 12, vertically arranged narrow strips 2-1 close to the corresponding edges (the left side edge of the front and the right side edge of the back 12) are respectively provided; when folded, several corresponding latches can be inserted into the narrow strips 2-1 one by one to lock them.

[0035] Furthermore, the outlet hole 10-2 has a smaller missing circle hole 10-21 in the center; the outer periphery of the outlet hole 10-2 is formed by a series of continuously arranged pinholes to create a tearable edge (i.e., a tearable edge); in use, the missing circle hole 10-21 can be used as a cable outlet as needed, or the larger outlet hole 10-2 can be used as a cable outlet after tearing along the pinholes.

[0036] Furthermore, a smaller cross-shaped cut 10-3 is provided next to the cable outlet 10-2; correspondingly, a semi-circular upper semi-circular hole 13-3 is provided on the left edge of the upper half of the front pad, and a semi-circular lower semi-circular hole 19-2 is provided on the left edge of the lower half of the front pad; when the upper half of the front pad and the lower half of the front pad are folded and spliced, the complete hole formed by the splicing of the upper semi-circular hole 13-3 and the lower semi-circular hole 19-2 corresponds exactly to the cross-shaped cut 10-3. A small hole 16-2 corresponding to the cross-shaped cut 10-3 is also provided on the middle layer 16 of the front. During use, the cable end that has been pulled out from the cable outlet can be inserted into the cross-shaped cut for clamping, so as to avoid the cable end retracting into the box and causing trouble for cable installation, and also to avoid the cable end dragging on the ground and getting contaminated when moving the cable pull box.

[0037] An inspection hole 11-1 is provided on the right side; the inspection hole is formed by connecting a straight folded edge and an arc-shaped tearable edge end to end; during the use of the cable pull box, the inspection hole can be torn open as needed to inspect the cables inside the box.

[0038] The tearable edge consists of multiple needle-shaped perforations arranged in a continuous pattern. After tearing along the tearable edge, the two parts on both sides of the tearable edge can be separated. In use, the tearable edge can be torn open or left intact as needed.

[0039] When this utility model is used for packaging cables, the steps for folding it to form a cable pull-out box are as follows:

[0040] 1. For example Figure 2 As shown; fold the bottom edge, right side, top surface, right side, and bottom surface 90 degrees along the folding edge, then align the bottom edge with the inside edge of the top edge of the bottom surface and connect them (by double-sided adhesive or staples) to form a rectangular shell (at this time, a cable tray with a bracket can be placed inside).

[0041] 2. Fold and close the two openings on both sides of the rectangle (the folding method is the same on both sides, so only the left side is described):

[0042] The steps for folding and closing the left opening of the rectangle are as follows: Fold the front 10, the upper half of the front padding 13, the middle layer of the front 16, and the lower half of the front padding 19 inward (i.e. fold inward towards the opening) by 90 degrees along their respective right-side fold lines; the folding order is: first fold the upper half of the front padding and the lower half of the front padding inward by 90 degrees, then fold the middle layer of the front padding inward by less than 90 degrees to cover the upper half of the front padding and the lower half of the front padding, and finally fold the front inward by less than 90 degrees to cover the middle side layer of the front.

[0043] 3. For example Figure 3As shown: During the process of folding the front to 90 degrees, align the left edge of the folded edge with and insert it into the strip slot 17-1 of the front middle layer; at the same time, during the process of folding the front middle layer to 90 degrees, align the latches on the edge with and insert them into the strip slit 2-1 on the left edge; finally, the front middle layer and the front are folded to 90 degrees at the same time, and the left opening of the rectangle is folded closed to complete the process.

[0044] 4. Following step 3, complete the folding and closing of the right-side opening of the rectangle; the resulting cable drawer box is as follows: Figure 4 As shown.

[0045] Example 2

[0046] This embodiment is basically the same as embodiment 1, except that the cardboard is cut along the fold line between the left side 17 and the top side 14 to divide it into two pieces, and an additional folded edge 22 is provided along the cut edge on the left side 17 or the top side 14. When forming the cable pull-out box, the additional folded edge must first be connected to the corresponding edge of the top side 14 or the left side 17 (by double-sided adhesive or staples) to form a cardboard with the same shape as in embodiment 1. The subsequent folding work is the same as in embodiment 1.

[0047] After receiving the cable packaging box, users can manually move the cable packaging box through the gripper hole; when installing the cable, they can open the inspection hole, reach into the box to find the cable end, and align the cable end with the outlet and extend it out of the box; the cable can then be continuously pulled out (the I-beam reel rotates on the bracket to unwind the cable at the same time).
