Description

Technical Field

[0001] This invention relates to the field of packaging and transportation, and more particularly to a combined knife card assembly and a pallet box. Background Technology

[0002] In the packaging and transportation industry, knife clips are widely used inside palletized boxes to divide the internal space of the box into several grid-like compartments, so that the items to be transported can be placed independently in each compartment, preventing the items from colliding with each other during transportation.

[0003] Traditional blade holders consist of several horizontal and vertical clamping plates intersecting each other, with shelves at the bottom for separation. Current methods for fixing these shelves involve laying individual shelves flat on the bottom of the blade holder and then securing them with adhesive. This manual adhesive application not only increases the number of steps and reduces production efficiency, but also results in the adhesive evaporating and producing an odor.

[0004] Patent CN212606448U proposes an integrated blade clamp structure, in which fixed partitions integrally formed with the base plate are arranged on both sides of the base plate, and the transverse partitions are inserted into the fixed partitions on both sides. Although this solution avoids adhesive bonding, the transverse partitions and fixed partitions rely solely on simple vertical slots for positioning and engagement. Due to the tolerances of the clamps themselves and the insertion gaps, the two have a large degree of vertical freedom after assembly, making them prone to relative loosening, resulting in insufficient rigidity of the overall structure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a combined blade card assembly.

[0006] In a first aspect, the present invention provides a combined knife holder assembly, comprising a shelf and a knife holder. The knife holder includes a plurality of transverse and longitudinal clamping plates, wherein the transverse and longitudinal clamping plates are interlocked to form a grid-like partition cavity for accommodating items. The shelf is disposed at the bottom of the knife holder, and fixed partitions bent upward in a vertical direction are provided on both sides of the shelf. The fixed partitions and the shelf are integrally formed, and the fixed partitions constitute the outer edge wall of the knife holder. The transverse clamping plates located at the edge of the knife holder are edge clamping plates, and the end of the edge clamping plate is provided with a first latch, the first latch being spaced from the edge of the end by a certain distance. A first end-holding portion is formed between the two; the end of the fixed partition is provided with a second latch, the second latch being spaced from the edge of the end to form a second end-holding portion between the two; both the first end-holding portion and the second end-holding portion are elastic sheet-like structures, the sheet-like structures are provided to form a first weak portion at the bend, the first end-holding portion and the second end-holding portion have a first state in which they bend along the first weak portion under the action of external force to allow the end of the edge-holding plate to cross with the end of the fixed partition, and a second state in which they spring back under the action of external force to form the first latch and the second latch engaging with each other.

[0007] Furthermore, the sheet-like structure has at least two first weak points, which are spaced apart and parallel to each other.

[0008] Furthermore, the edge plate is provided with a second weak part, which extends on the edge plate in the opposite direction to the opening of the first slot.

[0009] Furthermore, the extension directions of the first weak part and the second weak part are perpendicular to each other.

[0010] Furthermore, each weak point is a concave structure formed by creating notches or local thinning.

[0011] Furthermore, a third weak point is provided between the fixed partition and the shelf, which serves as the bending point where the fixed partition bends upward relative to the shelf.

[0012] Furthermore, the opening of the first bayonet is arranged facing upwards, and the opening of the second bayonet is in the opposite direction to that of the first bayonet.

[0013] Furthermore, the horizontal card plate located in the middle of the blade card is a middle card plate. The end of the middle card plate is provided with a third slot, and the middle of the fixed partition is provided with a fourth slot. The end of the middle card plate and the middle of the fixed partition are engaged with each other through the third slot and the fourth slot.

[0014] Furthermore, the opening direction of the end slot of each card plate is opposite to the opening direction of the middle slot, and the opening direction of the edge card plate is opposite to that of the corresponding position of the middle card plate.

[0015] In a second aspect, the present invention provides a enclosure box, including the above-described combined knife card assembly.

[0016] Compared with the prior art, the combined blade card assembly of the present invention has the following advantages: 1. By bending, nesting and springing the first and second end holding parts at the weak points, physical interlocking between the edge holding plate and the fixed partition is achieved, eliminating the need for glue, making it environmentally friendly and efficient in production and assembly; 2. The design of the weak part makes the deformation trajectory under external force during assembly clear, and the springback after crossing into place achieves locking, ensuring consistency and smoothness during batch assembly; 3. The first bayonet opens upwards, and the second bayonet faces the opposite direction. It is formed by bending upwards from both sides of the shelf with a fixed partition. After interlocking, the shelf and the blade are locked in the vertical position, which solves the problem of easy loosening of the traditional straight insertion structure.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the embodiments of this invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments described below are only for explaining this invention and are not intended to limit the scope of protection of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0023] like Figure 1As shown, this embodiment provides a combined blade holder assembly, which consists of a layer plate 1 serving as a support base and a blade holder 2 located above the layer plate 1. The layer plate 1 and the blade holder 2 are interlocked to form an integral structure.

[0024] like Figure 2 As shown, the blade holder 2 in this embodiment consists of several horizontal clamping plates 21 and several vertical clamping plates 22. Each horizontal clamping plate 21 and each vertical clamping plate 22 has a snap-fit ​​slot along its length that matches the thickness of the other plate. The horizontal clamping plates 21 and the vertical clamping plates 22 are assembled by interlocking to form the blade holder 2. During assembly, the horizontal clamping plates 21 and the vertical clamping plates 22 are aligned in a perpendicular cross configuration, so that the corresponding snap-fit ​​slots are inserted and nested into each other, thereby forming a grid-like partition cavity. The partition cavity is used to accommodate and separate the items to be transported, ensuring that the items do not squeeze or collide with each other during transportation.

[0025] In this embodiment, the layer 1 is adhered to the bottom of the blade holder 2. To avoid relying on adhesive for fixation between the layer 1 and the blade holder 2, as follows: Figure 2 As shown, the shelf 1 has integrally formed, upwardly bent fixed partitions 11 on both sides. After the fixed partitions 11 are flipped upward to a vertical state, they serve as the outer edge walls of the blade holders 2 on both sides. At this time, each longitudinal plate 22 is located between two fixed partitions 11. Both the longitudinal plates 22 and the fixed partitions 11 extend longitudinally and are arranged at equal intervals.

[0026] In this embodiment, the transverse clamping plate 21 is divided into an edge clamping plate 211 located at the edge of the blade clamping plate 2 and an intermediate clamping plate 212 located in the middle of the blade clamping plate 2, with each intermediate clamping plate 212 positioned between the two edge clamping plates 211. To lock the layer plate 1 and the blade clamping plate 2 together, an interlocking mechanism is provided at the end connection between the edge clamping plate 211 and the fixed partition plate 11. For example... Figure 3 As shown, the edge retaining plate 211 has a first retaining opening 31 with an upward opening cut out at its end using a die-cutting process. A certain distance is maintained between the first retaining opening 31 and the end edge of the edge retaining plate 211, thus forming a first end retaining portion 311 located between the first retaining opening 31 and the end edge at the end of the edge retaining plate 211. Similarly, a second retaining opening 32 with a downward opening is cut out at the end of the fixing partition 11, and a certain distance is also maintained between the second retaining opening 32 and the end edge of the fixing partition 11, forming a second end retaining portion 321.

[0027] To facilitate bending, the first end holding part 311 and the second end holding part 321 are provided with a first weak part 33 at their roots to guide the bending direction. The first weak part 33 may be a pre-pressed crease or groove, extending in the transverse or longitudinal direction. Since the cardboard and shelf 1 are made of resilient sheet materials such as corrugated cardboard or plastic sheet, the two cut end holding parts 311 and 321 have good bending elasticity.

[0028] like Figures 4a-4c As shown, during assembly, the operator applies force and uses the first weak part 33 as the bending point to elastically bend the first end clamping part 311 and the second end clamping part 321 in a direction that is relatively away from each other, so that the clamping parts that were originally interfering can avoid the misalignment space. After that, the end of the edge clamping plate 211 passes over the end of the fixed partition 11 to achieve cross overlap.

[0029] When the end of the edge plate 211 intersects with the end of the fixed partition 11 at a predetermined position, the external force applied to the end holding part is removed, and the first end holding part 311 and the second end holding part 321 spring back to their original position and return to a straight state. The first latch 31 and the second latch 32 engage and interlock with each other to form an interlock.

[0030] In this embodiment, the structure achieves physical interlocking between the edge plate 211 and the fixed partition 11 by bending, nesting and springing the first and second end holding parts 311 and 321 at the weak part 33. This interlocking structure will not fail or fall off due to vibration or moisture during transportation (the glue is prone to aging), and it can be assembled quickly, saving manpower and auxiliary material costs.

[0031] like Figure 3 As shown, as an improvement, this embodiment further optimizes the distribution of the weak points 33. At least two first weak points 33 are provided on the sheet structure, with each first weak point 33 spaced apart and parallel to the others. By providing multiple parallel weak points 33, when the retaining part is bent by external force, a hinge area with a certain width is formed, achieving a larger bending angle, while avoiding fiber breakage inside the retaining plate, increasing durability for repeated assembly and disassembly.

[0032] As an alternative improvement, a second weak portion 34 is added to the edge plate 211. The second weak portion 34 extends in the opposite direction to the opening of the first latch 31 and is disposed on the body of the edge plate 211. The design of the second weak portion 34 allows the operator to elastically bend the end of the edge plate 211, temporarily shortening the end of the edge plate 211, thereby allowing the entire blade holder 2 grid to move downwards to the lower layer 1 to a fitted state. Furthermore, the first weak portion 33 and the second weak portion 34 are set with mutually perpendicular extending directions. Specifically, the first weak portion 33 is a crease along the length direction of the plate, serving the outward folding action of the end holding part, and the second weak portion 34 is a crease along the width direction of the plate, serving end clearance. These two weak portions are arranged perpendicularly in the end connection area and do not interfere with each other.

[0033] In this embodiment, the first weak part 33, the second weak part 34, etc., are recessed structures formed by notching or local thinning. During manufacturing, "V" or "U" shaped grooves can be cut into the cardboard or partition using a die-cutting process, or the cardboard thickness can be locally thinned by applying pressure on a creasing machine. This recessed structure ensures that the cardboard or partition deforms at a predetermined position when it is bent, avoiding random tearing or skewing deformation and ensuring the consistency of batch assembly.

[0034] As another improvement, such as Figure 5 As shown, a third weak portion 35 is provided between the fixed partition 11 and the shelf 1. The third weak portion 35 serves as the bending point where the fixed partition 11 bends upward relative to the shelf 1. When not assembled, the third weak portion 35 allows the fixed partition 11 to be in the same plane as the shelf 1, facilitating stacking. When needed, the operator folds the fixed partition 11 upward along the third weak portion 35. The third weak portion 35 acts as a hinge, effectively improving the internal stress at the bending point and ensuring the perpendicularity of the outer sidewall of the knife holder 2.

[0035] This embodiment optimizes the bayonet layout of the blade holder 2, forming a design where the openings of the end bayonet and the middle bayonet are reversed.

[0036] like Figure 5 As shown, the end slot (i.e., the first slot 31) of the edge plate 211 faces upward, while the middle slot 41, which is used to engage with the longitudinal plate 22, faces downward. In conventional blade clips 2, the slots of the transverse plates 21 have the same opening direction. In this embodiment, by setting the end and middle slots of the edge plate 211 in opposite directions, when the middle sinks, the upward-facing slot of the end opening 31 is blocked by the edge fixing partition 11. Through this arrangement of openings in opposite directions, a mutually locking mechanical system is formed inside and outside the mesh, preventing the blade clip 2 from opening, detaching, or twisting as a whole, effectively improving the deformation resistance of the mesh structure.

[0037] Furthermore, the longitudinal clamping plate 22 also features a reversed clamping direction. The end clamping slot 42 of the longitudinal clamping plate 22, which connects to the edge clamping plate 211, has an opening direction opposite to that of the central clamping slot 43, which connects to the intermediate clamping plate 212. In this way, the entire blade clamp assembly achieves opposing restraints between the end locking force and the internal insertion force in both the transverse and longitudinal directions, effectively preventing the blade clamp 2 from opening, detaching, or twisting during frequent use.

[0038] As a preferred design, the end of the intermediate clamping plate 212 is provided with a third latch 44, and the middle of the fixed partition plate 11 is provided with a fourth latch 45. The end of the intermediate clamping plate 212 and the middle of the fixed partition plate 11 are interlocked by the third latch 44 and the fourth latch 45. The opening direction of the end latch (i.e., the third latch 44) of the intermediate clamping plate 212 used to interlock the fixed partition plate 11 is opposite to the opening direction of the latch 46 in the middle of the plate used to interlock the longitudinal clamping plate 22. At this time, the fixed partition plate 11 is not only locked to the edge clamping plate 211 at the end, but also has multiple support points added in the middle of its long side span. On the one hand, the fixed partition plate 11, as one of the longitudinal clamping plates 22, participates in the opposite restraint between the end locking force and the internal insertion force. On the other hand, the long strip fixed partition plate 11 is divided into several short force-bearing segments. When the operator grasps the fixed partition plate 11 with both hands to remove the knife clamp assembly, the fixed partition plate 11 will not bend or deform inward, further ensuring the shape maintenance of the entire knife clamp assembly during the transportation process.

[0039] The present invention also provides a collapsible box, in which the above-mentioned combined knife-card assembly is placed. Thanks to the integral molding of the shelf 1 and the fixed partitions 11 on both sides and the physical self-locking structure, the operator can simply hold the fixed partitions 11 on both sides during daily loading and unloading to smoothly lift the entire layer of knife-card assembly loaded with products out of the collapsible box, thereby improving the efficiency of logistics transfer.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although detailed descriptions have been provided with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
