[0003] With increasing environmental awareness and growing demand for resource recycling, paper lining grids are now commonly used in lighting packaging. These lining grids typically employ a grid-like cardboard structure, but the traditional grid-like cardboard structure relies on manual insertion of clips, which is cumbersome, time-consuming, and labor-intensive. Furthermore, the bottomless design of the lining components results in insufficient overall stability after the lighting fixtures are installed, making them prone to scattering and tipping during production line operations or forklift transport, posing safety hazards.

[0018] Figure 1 This is a perspective view of the overall structure in an embodiment of the present utility model; Figure 2 This is a schematic diagram of the connection of the inner lining assembly in an embodiment of this utility model.

[0019] In the diagram, 1 is the enclosure box; 2 is the inner lining assembly; 3 is the inner lining upright; and 4 is the inner lining side panel. Detailed Implementation

[0020] like Figures 1 to 2 As shown, this embodiment provides a reusable packaging liner for a lamp, including four liner components 2 evenly distributed along the inner dimensions of the enclosure box 1, and the liner components 2 are detachably connected to each other through a connecting structure.

[0021] like Figure 1As shown, the connecting structure includes Velcro and auxiliary snap fasteners. The Velcro is set on the mating surface of adjacent inner lining components 2 and is fixed by sewing or pasting. The auxiliary snap fasteners are set at the edge mating point of the inner lining components 2 to enhance the connection stability. The inner lining has at least two groove structures on opposite sides, and the groove structures are fixedly connected to the side wall of the inner lining component 2. Each inner lining component 2 can be folded inward along the connecting structure. In the folded state, it can be stored inside the enclosure box 1 as a whole, realizing the complete recycling of the enclosure box 1.

[0022] Specifically, the four evenly spaced units are quickly positioned via flexible Velcro connections, allowing operators to complete initial assembly simply by aligning the unit edges. Auxiliary snap-fits provide rigid constraints at the unit mating edges; once the light fixture is installed, the mechanical locking action of the snaps resists lateral impacts during transport. The Velcro sewing method accommodates the production needs of units made of different materials, such as foam or recycled plastic. The grooved structures on both sides form an integral structure with the unit sidewalls, preventing stress concentration and connection failure during handling. In the folded state, the units are stacked along their thickness, maintaining their folded shape through Velcro adhesion, significantly reducing storage space requirements.

[0023] The Velcro fasteners consist of a male and a female side, respectively positioned at the edges of the mating surfaces of adjacent inner liner components 2. During assembly, the male and female sides quickly bond together by pressing. The edge placement concentrates the adhesive force on both sides of the mating surfaces, preventing connection failure due to misalignment. When folding for storage, the Velcro fasteners can be easily removed by peeling them off along the edges, eliminating the need to disassemble each clip individually, simplifying the process. The separate design of the male and female sides allows the inner liner components 2 to align naturally when folded, reducing localized stress caused by misalignment and extending their lifespan. The auxiliary snap-fit ​​fastener is a flexible plastic snap-fit ​​fastener, including a protrusion on the edge of the inner lining upright plate 3 and a corresponding groove on the edge of the inner lining side plate 4. When adjacent inner lining components 2 are mated, the protrusion embeds into the groove through elastic deformation. The elastic properties of the plastic material allow the snap-fit ​​to generate a continuous elastic restoring force after engagement, forming a stable clamping state. The mating surfaces of the protrusion and the groove are geometrically constrained, forming a physical limit in the horizontal direction to prevent relative sliding between components. The deformation capacity of the flexible snap-fit ​​allows for certain tolerances during assembly, avoiding assembly failure due to processing errors. When the snap-fit ​​structure is distributed along the mating edge, multiple snap-fits share the load, making the connection surface evenly stressed, thereby improving the overall structure's resistance to displacement under vibration or impact conditions.

[0024] Four inner lining components 2 are arranged linearly and evenly along the length or width of the enclosure box 1. The length or width of each unit is matched to one-quarter of the internal dimensions of the enclosure box 1. The four inner lining components 2 are arranged sequentially along this direction, and the length of each component is set to one-quarter of the total internal length of the enclosure box 1. During installation, the operator only needs to place the inner lining components 2 sequentially along a straight line. This linear arrangement eliminates the lateral cross-positioning steps required by traditional grid structures. The precise correspondence between the dimensions of each unit and one-quarter of the enclosure box 1 ensures that adjacent inner lining components 2 automatically form a gapless continuous plane when mated, avoiding assembly misalignment caused by dimensional deviations. This layout allows the inner lining components 2 to evenly distribute the load during transportation, preventing structural deformation caused by localized stress concentration.

[0025] The connecting structure also includes a positioning pin and a corresponding insertion hole located at the bottom of the inner liner assembly 2. The positioning pin and the insertion hole are fitted with a clearance fit to achieve vertical positioning. When the inner liner assembly 2 is aligned horizontally, the hemispherical guide surface at the top of the positioning pin guides it into the corresponding insertion hole, and the elastic buffer layer absorbs the assembly impact force. The positioning pin and the insertion hole form a vertical physical limit, constraining the vertical displacement of the inner liner assembly 2 under vibration or tilting conditions. The clearance fit allows for slight horizontal adjustment of the assembly, while the friction of the contact surface generates a damping effect to prevent the assembly from loosening during transportation. This structure, together with the horizontal connection of Velcro and buckles, forms a three-dimensional constraint system, jointly improving the overall impact resistance of the inner liner.

[0026] Each inner liner component 2 has a reinforcing rib structure on its sidewalls, with the ribs extending along the height direction and integrally formed with the unit body. Specifically, by setting reinforcing ribs extending along the height direction on the sidewalls of the inner liner component 2, a continuous longitudinal support skeleton is formed. When the packaging is subjected to external compression or vibration impact, the reinforcing ribs distribute the load vertically to the overall structure. The integrated construction of the reinforcing ribs and sidewalls avoids stress concentration areas caused by traditional welding or bonding processes, allowing the sidewalls to maintain structural integrity when bearing the weight of the lamp and transportation loads. This construction method maintains the lightweight characteristics of the inner liner while improving the resistance to deformation through a three-dimensionally distributed rib network.

[0027] At least two auxiliary snap-fit ​​fasteners are provided on the mating edge of each inner liner component 2, evenly distributed along the edge length. When adjacent inner liner components 2 are mated, multi-point constraint is formed through the synergistic action of at least two auxiliary snap-fit ​​fasteners. When lateral shear force or longitudinal torsional force is generated during transportation, each snap-fit ​​fastener bears part of the load, preventing single snap-fit ​​fastener from failing due to stress concentration. At the same time, the evenly distributed snap-fit ​​fasteners can limit the relative displacement of the inner liner components 2 on the mating surface, preventing loosening of the connection due to local deformation.

[0028] The locating pin has a cylindrical structure with a hemispherical guide surface at the top and an elastic buffer layer on the inner wall of the insertion hole. The cylindrical structure avoids stress concentration caused by sharp corners during vertical insertion, ensuring a uniform contact surface between the locating pin and the insertion hole. The hemispherical guide surface guides the locating pin to automatically correct any offset angle during the initial insertion stage, reducing the difficulty of manual alignment. The elastic buffer layer undergoes elastic compression upon insertion, buffering the impact force and filling the gap between the locating pin and the insertion hole through deformation, eliminating loosening caused by manufacturing errors. The buffer layer on the inner wall of the insertion hole complements the rigid structure of the locating pin, reducing rigid friction between components while maintaining vertical positioning accuracy.

[0029] The inner wall of the enclosure box 1 has a limiting protrusion corresponding to the storage position of the folded lining. The limiting protrusion and the end of the lining form a snap-fit ​​engagement. Specifically, when the lining assembly 2 is folded along the connecting structure, the folded end of the lining is pushed into the limiting protrusion area on the inner wall of the enclosure box 1. The vertical sidewall of the limiting protrusion contacts the plane of the lining end to form the first limiting, while the barb structure at the top of the protrusion is embedded in the pre-set groove at the lining end to form the second limiting. This dual constraint mechanism offsets the vibration and impact forces generated during transportation through the rigid contact surface, while maintaining the folded shape of the lining assembly 2 by utilizing the self-locking characteristics of the snap-fit ​​structure.

[0030] The peripheral surface of the groove structure is provided with anti-slip texture, which is distributed in a wavy pattern along the length of the groove structure. During handling, when lateral displacement occurs, the alternating peaks and troughs of the anti-slip texture provide segmented resistance to the fingers, preventing slippage in one direction. The texture continuously covers the entire gripping area along its length, ensuring that all parts of the palm are in contact with the texture, while eliminating pressure from the annular texture on localized areas of the palm.

[0031] The working principle of this utility model: The four inner lining components are initially positioned by quick-attaching the male and female sides of the Velcro straps. The protrusions of the auxiliary snap fasteners embed into the grooves to form a rigid constraint, and the gap fit between the bottom positioning pin and the insertion hole completes vertical positioning, together forming a three-dimensional stable structure. After the lamp is placed inside, the reinforced sidewalls and ring support structure evenly distribute the load, and the anti-slip texture of the grooved structure facilitates handling. For recycling, the Velcro straps and snap fasteners are separated, and each component is folded along its thickness direction and secured by the limiting protrusions on the inner wall of the enclosure, enabling the entire set to be recycled. This solves the problems of cumbersome assembly, poor stability, and lack of recyclability associated with traditional paper inner linings.

[0032] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
