Description

Technical Field

[0001] This utility model relates to the field of packaging structure technology, and in particular to an EPE pearl cotton packaging structure. Background Technology

[0002] EPE (Expandable Polyethylene) foam, a packaging material with excellent properties such as lightweight, flexibility, shock absorption, cushioning, and impact resistance, is widely used in the packaging of various products, including electronics, home appliances, precision instruments, and handicrafts, due to its environmentally friendly and recyclable characteristics. It effectively reduces damage caused by collisions and compression during transportation and storage. Packaging structures based on EPE foam typically need to balance core requirements such as product securing, cushioning protection, and space utilization to adapt to packaging scenarios for different types and sizes of products.

[0003] However, the existing EPE (Expanded Polyethylene) packaging structure still has certain shortcomings: Most packaging structures have a fixed internal space design, which cannot flexibly adjust the internal partition space according to the size of the product to be packaged. This results in poor adaptability to products of different specifications, and is prone to space waste or unstable product fixation. In addition, the partition components are mostly fixedly connected to the packaging box body and cannot be removed as a whole. When large items need to be packaged, the partition components will occupy internal space and reduce the space utilization rate of the packaging structure.

[0004] Therefore, we propose an EPE pearl cotton packaging structure. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology. Most packaging structures have a fixed internal space design, which cannot flexibly adjust the internal partition space according to the size of the product to be packaged. This results in poor adaptability to products of different specifications and is prone to space waste or unstable product fixation. In addition, the partition components are mostly fixedly connected to the packaging box body and cannot be removed as a whole. When large items need to be packaged, the partition components will occupy internal space and reduce the space utilization rate of the packaging structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An EPE (Expanded Polyethylene) packaging structure includes: a packaging box body with a cover plate on the top; a cavity formed in the inner walls of the packaging box body; and several supporting and cushioning rubber pads fixedly disposed inside the cavity for auxiliary support and cushioning. A space adjustment mechanism is installed inside the packaging box body, including a horizontal partition structure, a vertical adjustment partition structure, and a locking structure. The horizontal partition structure is used to divide the internal space of the packaging box body horizontally. The vertical adjustment partition structure is used to slide at the horizontal partition structure to vertically divide the internal space of the packaging box body. The locking structure is used to lock and fix the vertical adjustment partition structure after adjustment. Two limiting sliding mechanisms are set on both sides inside the packaging box body to limit and fix the space adjustment mechanism, so that the space adjustment mechanism can be installed as a whole inside the packaging box body, or the space adjustment mechanism can be taken out as a whole when needed to obtain a larger storage space.

[0007] As a preferred embodiment of this utility model, the transverse partition structure includes: a transverse partition plate disposed inside the packaging box body; two pull-out sliding seats fixedly disposed on the two side walls of the transverse partition plate; a sliding groove formed at the transverse partition plate and located at the center; and a connecting groove formed at the transverse partition plate and near the top.

[0008] As a preferred embodiment of this utility model, the vertical adjustable partition structure includes: a vertical partition plate, disposed inside the packaging box body and connected to the horizontal partition plate; a reserved slot, opened at the center of the vertical partition plate, for fitting with the horizontal partition plate between the connecting slot and the sliding slot; a sliding block, fixedly disposed at the center of the vertical partition plate, for sliding connection with the sliding slot; and a locking slot, opened at the vertical partition plate and near the top, for connecting with the connecting slot.

[0009] As a preferred embodiment of this utility model, the locking structure includes: a rotating threaded rod, threadedly connected to the top of the vertical partition plate and located above the locking groove; a locking block, fixedly disposed at the bottom of the rotating threaded rod and located inside the locking groove; and a locking rubber pad, fixedly disposed at the bottom of the locking block.

[0010] As a preferred embodiment of this utility model, when the first rotating cap rotates, it drives the rotating threaded rod to rotate, thereby causing the locking block and locking rubber pad to descend and contact and lock the horizontal partition plate; the vertical partition plate is slidably connected to the sliding groove of the horizontal partition plate through a sliding block.

[0011] As a preferred embodiment of this utility model, the limiting sliding mechanism includes: a sliding groove, which is formed on the side wall inside the packaging box body and is used to slide and connect the pull-out sliding seat; threaded holes, which are formed at both ends of the sliding groove; a fixed seat, which is set at the top of the sliding groove; an abutment block, which is fixedly set at the bottom of the fixed seat and is used to abut the top of the pull-out sliding seat; a second rotating cap, which is set at the top of the fixed seat; and a locking threaded rod, which passes through the top of the fixed seat and is threadedly connected to the threaded hole to fix the fixed seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, by setting a space adjustment mechanism, the horizontal partition structure can horizontally divide the interior of the packaging box body, and the vertical adjustment partition structure can slide along the horizontal partition structure to achieve vertical division. The two work together to flexibly adjust the internal partition space according to the size of the product to be packaged, avoiding the problems of poor adaptability, space waste or unstable product fixation caused by traditional fixed space design, and can adapt to the packaging needs of products of different specifications.

[0013] The locking structure lowers the locking block and locking rubber pad by rotating the threaded rod to contact the horizontal partition plate. This allows for a stable lock after the vertical adjustment of the partition structure is completed. This solves the problems of poor locking effect and easy displacement due to vibration in traditional adjustable partition structures, ensuring the stability of the partition state during transportation.

[0014] The limiting sliding mechanism, through the cooperation of the sliding groove and the pull-out sliding seat, as well as the limiting fixation of the fixed seat and the abutment block, allows the space adjustment mechanism to be installed as a whole inside the packaging box, and can also be taken out as a whole when needed. This avoids the problem of space occupation when packaging large items caused by the fixed connection between the partition component and the packaging box body, and effectively improves the space utilization rate of the packaging structure.

However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0021] like Figure 1-9As shown, this utility model provides a technical solution: an EPE pearl cotton packaging structure, including: a packaging box body 10, and a cover plate 20 is provided on the top of the packaging box body 10; Cavity 30 is formed on the inner walls of the packaging box body 10. Several supporting and buffering rubber pads 40 are fixedly installed inside the cavity 30 for auxiliary support and buffering; The space adjustment mechanism 60 is located inside the packaging box body 10 and includes a horizontal partition structure, a vertical adjustment partition structure and a locking structure. The horizontal partition structure is used to divide the internal space of the packaging box body 10 horizontally. The vertical adjustment partition structure is used to slide at the horizontal partition structure to vertically divide the internal space of the packaging box body 10. The locking structure is used to lock and fix the vertical adjustment partition structure after it is adjusted. Two limiting sliding mechanisms 70 are set on both sides inside the packaging box body 10 to limit and fix the space adjustment mechanism 60, so that the space adjustment mechanism 60 can be installed as a whole inside the packaging box body 10, or the space adjustment mechanism 60 can be taken out as a whole when needed to obtain a larger storage space.

[0022] The packaging box body 10 serves as the load-bearing base, and the cover plate 20 seals the top for protection. The cavity 30 on the inner walls provides installation space for the supporting cushioning rubber pad 40. The rubber pad absorbs the impact force through elastic deformation, assists in supporting the internal items, and enhances the cushioning performance. In the space adjustment mechanism 60, the horizontal partition structure first divides the horizontal space, and the vertical adjustment partition structure slides along it to adjust the vertical partition. The locking structure fixes the positions of both through mechanical force to prevent vibration and displacement. The limiting sliding mechanism 70 realizes the installation (fixed seat 703 is fastened by locking threaded rod 706, and the abutment block 704 limits) and removal (after loosening the threaded rod, the mechanism slides out along the sliding groove 701) of the space adjustment mechanism 60 through the sliding cooperation of the pull-out sliding seat 602 and the sliding groove 701, flexibly adapting to the packaging needs of items of different sizes.

[0023] The horizontal partition structure includes: A horizontal partition 601 is disposed inside the packaging box body 10; Two pull-out sliding seats 602 are fixedly installed on the two side walls of the transverse partition plate 601; The sliding groove 603 is formed at the transverse partition plate 601 and is located at the center; The connecting groove 604 is provided at the horizontal partition plate 601, near the top.

[0024] The horizontal partition 601 is arranged horizontally to directly divide the space inside the box; the two side pull-out sliding seats 602 cooperate with the sliding groove 701 of the limiting sliding mechanism 70 to provide support for the overall sliding of the space adjustment mechanism 60; the central sliding groove 603 accommodates the sliding block 607 of the vertical partition 605, so that the vertical partition 605 can slide horizontally along the groove to adjust its position; the top connecting groove 604 corresponds to the locking groove 608 of the vertical partition 605, providing an abutment area for the locking block 610 of the locking structure to achieve locking of the horizontal and vertical partition structures.

[0025] The vertical adjustable partition structure includes: A vertical divider 605 is disposed inside the packaging box body 10 and is connected to the horizontal divider 601; A reserved slot 606 is provided at the center of the vertical partition plate 605 to be adapted to the horizontal partition plate 601 between the connecting slot 604 and the sliding slot 603; The sliding block 607 is fixedly installed at the center of the vertical partition plate 605 and is used to slide in connection with the sliding groove 603; The locking groove 608 is provided at the vertical partition plate 605, near the top, and is used to connect with the connecting groove 604.

[0026] The vertical partition plate 605 spans across the horizontal partition plate 601. The central pre-reserved slot 606 is adapted to the plate body between the sliding slot 603 and the connecting slot 604 on the horizontal partition plate 601 to ensure stable installation. The sliding block 607 is embedded in the sliding slot 603 to form a sliding pair. When pushed by external force, the vertical partition plate 605 can slide horizontally along the slot to adjust the width of the vertical partition. The top locking slot 608 corresponds vertically to the connecting slot 604, providing a space for the locking block 610 of the locking structure. When locked, both restrict the sliding of the vertical partition plate 605.

[0027] The locking structure includes: Rotate the threaded rod 609, which is threaded to the top of the vertical partition plate 605 and located above the locking groove 608; The locking block 610 is fixedly installed at the bottom of the rotating threaded rod 609 and located inside the locking groove 608; The locking rubber pad 611 is fixedly installed at the bottom of the locking block 610.

[0028] The threaded rod 609 is threadedly connected to the vertical partition plate 605. When the first rotating cap 612 is rotated, the threaded rod feeds downward along the axial direction, causing the locking block 610 and the locking rubber pad 611 to move downward, embed into the locking groove 608 and abut against the connecting groove 604 area of ​​the horizontal partition plate 601. The locking rubber pad 611 increases friction through elasticity, strengthens the locking effect, and at the same time buffers the locking impact force to avoid damage to the partition plate, thus achieving a stable lock of the horizontal and vertical partition structures.

[0029] When the first rotating cap 612 rotates, it drives the rotating threaded rod 609 to rotate, which in turn drives the locking block 610 and the locking rubber pad 611 to descend and contact and lock the transverse partition plate 601. The vertical partition plate 605 is slidably connected to the sliding groove 603 of the horizontal partition plate 601 via the sliding block 607.

[0030] The first rotating cap 612 provides an operating end. When rotated clockwise, it coaxially drives the rotating threaded rod 609 to rotate. The threaded rod is fed downward by the threaded transmission, pushing the locking block 610 and the locking rubber pad 611 to abut against the transverse partition plate 601. The positions of the two are locked by the thread self-locking and the rubber friction. When unlocked (rotating the cap counterclockwise), the threaded rod moves upward, the rubber pad disengages, and the vertical partition plate 605 can slide laterally along the sliding groove 603 via the sliding block 607, flexibly adjusting the position of the vertical partition.

[0031] The limiting slide mechanism 70 includes: A sliding groove 701 is formed on the side wall inside the packaging box body 10 and is used to slide and connect the pull-out sliding seat 602. Threaded holes 702 are provided at both ends of the sliding groove 701; The fixing seat 703 is set at the top of the sliding groove 701; The abutment block 704 is fixedly installed at the bottom of the fixed base 703 and is used to abut the top of the pull-out sliding base 602; The second rotating cap 705 is disposed on the top of the fixed base 703; The locking threaded rod 706 passes through the top of the fixed seat 703 and is threadedly connected to the threaded hole 702 to fix the fixed seat 703.

[0032] The sliding groove 701 provides a sliding track for the sliding seat 602. During installation, the sliding seat is inserted into the groove, allowing the space adjustment mechanism 60 to slide into the box. The fixed seat 703 is placed at the top of the groove, and the bottom abutment block 704 abuts against the top of the sliding seat, restricting its upward sliding. Rotating the second rotating cap 705 drives the locking threaded rod 706 to be screwed into the threaded hole 702, tightening the fixed seat 703 and achieving the limiting and fixing of the space adjustment mechanism 60. When removing, rotating the cap in the opposite direction causes the threaded rod to come out, lifting the fixed seat 703. The sliding seat slides outward along the sliding groove 701, removing the entire space adjustment mechanism 60 and releasing the complete space inside the box.

[0033] Workflow 1. Loading / unloading decision of space adjustment mechanism 60 (adapting to packaging requirements) Scenario A: Packing large items (requires ample space): ①Operation limit sliding mechanism 70: Rotate the second rotating cap 705, loosen the locking threaded rod 706, lift the fixed seat 703, and release the top limit on the pull-out sliding seat 602; ② Remove the space adjustment mechanism 60: Slide the sliding seat 602 outward along the sliding groove 701 to remove the space adjustment mechanism 60 as a whole, and a complete storage space is formed inside the packaging box body 10.

[0034] Scenario B: Packaging multiple / irregularly shaped items (requiring separate spaces): ①Installation space adjustment mechanism 60: Insert the pull-out sliding seat 602 into the sliding groove 701 and slide it to the preset position inside the box; ② Fixed limit: Lower the fixed seat 703 so that the abutment block 704 abuts against the top of the withdrawable sliding seat 602. Rotate the second rotating cap 705 and screw the locking threaded rod 706 into the threaded hole 702 to tighten the fixed seat 703 and complete the limit installation of the space adjustment mechanism 60.

[0035] 2. "Adjustment / Locking" of Internal Divided Spaces (for Scenario B) Horizontal division base: The horizontal partition plate 601 pre-divides the horizontal area inside the box (if adjustment is required, it can be finely adjusted by sliding mechanism, based on the actual position after installation).

[0036] Vertical zone adjustment: ① Push the vertical divider 605 so that its sliding block 607 moves laterally along the sliding groove 603 of the horizontal divider 601, and adjust the width of the vertical partition until it fits the size of the item. ② During the process, the reserved slot 606 is adapted to the plate body of the horizontal partition plate 601 to ensure the stable erection of the vertical partition plate 605.

[0037] Locking and fixing: Rotate the first rotating cap 612, which drives the rotating threaded rod 609 to feed downward, so that the locking block 610 carrying the locking rubber pad 611 is embedded in the locking groove 608 and abuts against the connecting groove 604 area of ​​the transverse partition plate 601. By utilizing the self-locking thread and rubber friction, the relative positions of the vertical partition plate 605 and the horizontal partition plate 601 are locked to prevent displacement caused by transportation vibration.

[0038] 3. Packaging and cushioning of goods Item placement: Place the item in the designated area, with the supporting cushioning rubber pad 40 inside the cavity 30 fitting against the side of the item; Cushioning Protection: During transportation or collision, the supporting cushioning rubber pad 40 absorbs the impact force through elastic deformation, assists in supporting the item, and reduces bump damage; Sealing: Cover with the cover plate 20 to seal the main body of the packaging box 10, and the packaging is complete.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
