Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a food delivery combination packaging box. Background Technology

[0002] The food delivery modular packaging box is a packaging container designed specifically for food delivery scenarios. Its core feature is that it enables the flexible splicing and combination of multiple boxes through a pre-set assembly structure, while taking into account basic functions such as sealing and protection, in order to meet the needs of space utilization, cargo classification and transportation stability in the food delivery process.

[0003] Traditional stackable packaging boxes are typically individual units, relying on their own weight or simple clips for stacking. Since stacking is achieved only through the contact of the top and bottom surfaces without side support, they are prone to tilting or collapsing during transport due to bumps or sudden braking. This risk increases significantly when stacking more than three layers, requiring additional ropes for securing them and adding to the handling process. Furthermore, slight wobbling between individual boxes can create gaps, preventing a tight, integrated structure and wasting transport space. The lack of side connections prevents lateral capacity expansion, limiting vertical stacking and restricting vehicle height. The lack of a unified load-bearing point after stacking makes them unusable for forklifts or other handling equipment, necessitating disassembly and handling layer by layer, resulting in high labor costs. Additionally, the high center of gravity in a stacked state makes them prone to tipping during transport, posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a modular packaging box for food delivery, which has the advantage of enabling precise and stable splicing of the upper, lower and side parts of the box, and solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A food delivery modular packaging box includes a packaging box body, a sealed box door hinged to the upper end of the packaging box body, a first side assembly component for side assembly, a second side assembly component for assembling two other sets of sides, a bottom assembly plate installed at the bottom of the packaging box body, symmetrical insertion slots on the upper surface of the sealed box door, and insertion plates installed on both sides of the upper end of the sealed box door. The first side assembly component includes an assembly frame plate installed on one side of the outer end of the packaging box body, and an assembly groove is provided inside the assembly frame plate.

[0007] Preferably, a sealing frame strip is installed at the lower end of the sealed box door, and a sealing groove is provided on the upper surface of the sealed box body to cooperate with the sealing frame strip.

[0008] It is worth noting that the sealing strip can significantly improve the overall sealing performance of the packaging box. On the one hand, it can effectively prevent external dust, moisture, and odors from seeping into the box, avoiding food contamination. On the other hand, if used for cold chain distribution, it can reduce the leakage of cold air inside the box and extend the shelf life of the food. At the same time, the sealing structure can also prevent the leakage of juices from the food inside the box, keeping the transportation environment clean. However, it is necessary to use wear-resistant and low-temperature resistant elastic materials, such as food-grade silicone, to avoid the squeezing and friction caused by frequent opening and closing of the box door, which could deform or break the strip and affect the sealing effect.

[0009] Preferably, positioning blocks are installed at both the upper and lower ends of the inner wall of the assembly frame plate, a fixed side plate is installed at one end of the outer side of the packaging box body, and insertion holes are installed inside the assembly frame plate and the fixed side plate.

[0010] It is worth noting that: the positioning blocks provide a precise vertical positioning reference for subsequent enclosure assembly, avoiding left-right offset or tilting during assembly and improving assembly efficiency; the fixed side plates enhance the structural strength of the sides of the enclosure body, reducing deformation of the enclosure due to collisions during transportation; however, it is important to note that the height and thickness of the positioning blocks must match the subsequent positioning slots. If the blocks are too thick, insertion will be difficult; if they are too thin, they will easily loosen and lose their positioning function.

[0011] Preferably, an assembly protrusion that matches the assembly groove is installed on the other side of the packaging box body, and positioning slots that match the positioning blocks are opened at the upper and lower ends of the assembly protrusion.

[0012] It is worth noting that the fit between the assembly convex plate and the assembly groove achieves the initial mechanical connection between the two sides of the box, providing a basic framework for the assembly; the cooperation between the positioning slot and the positioning block further restricts the relative movement of the box in the vertical direction, preventing the box from "misalignment" due to bumps after assembly, making the overall structure more stable; however, it should be noted that the depth of the positioning slot should be slightly greater than the height of the positioning block to ensure that the block can be fully embedded, while avoiding excessive depth that may cause deformation of the block.

[0013] Preferably, the side end of the assembly convex plate is provided with a mating insertion hole that is inserted and installed in conjunction with the insertion hole. A locking rod is detachably connected to the outside of the insertion hole and the mating insertion hole, and a locking screw is installed on the side end of the locking rod.

[0014] It is worth noting that by inserting the locking rod through the insertion hole and the mating hole, and then fixing it with the locking nut, a "mechanical locking" is formed, which upgrades the assembled box from "initial fit" to "rigid connection", significantly improving the overall impact resistance. Even in the transportation environment of sudden braking and bumpy conditions, the box is not easy to separate. However, it is recommended that the locking rod and locking nut be made of rust-proof material to avoid rusting in humid environments, which may cause the nut to become impossible to tighten or the rod to break.

[0015] Preferably, the second side-mounted component includes a combined groove opened on the other side of the outer side of the packaging box body. The side end of the packaging box body is equipped with snap-fit ​​side blocks on both sides of the combined groove. The snap-fit ​​side blocks are provided with a first mounting screw hole through the inside. The side end of the packaging box body is equipped with a bonding horizontal plate above the combined groove.

[0016] It is worth noting that the snap-fit ​​side blocks restrict the lateral movement of the expansion components from both sides to prevent left and right wobbling after assembly; however, it is important to ensure that the threads of the first mounting screw hole are clear and the hole depth is sufficient to prevent stripping of the threads or failure to secure the bolt completely when it is screwed in.

[0017] Preferably, an assembly side plate is installed on the side end of the packaging box body, and a combination protrusion is installed on the outer side of the assembly side plate to fit the combination groove. A second mounting screw hole is opened inside the fitting cross plate and at the top of the assembly side plate. A snap-fit ​​side groove is opened on both sides of the assembly side plate to cooperate with the snap-fit ​​side block.

[0018] It is worth noting that the second mounting screw hole mates with the screw hole of the fitting horizontal plate, and the connection gap is further eliminated by bolt fixing, so that the side plate can withstand greater lateral pressure; however, it should be noted that the inner wall of the snap-fit ​​side groove must be smooth to reduce friction and wear with the snap-fit ​​side block and extend service life.

[0019] Preferably, the lower end of the bottom assembly plate is equipped with a plug-in bottom block that fits into the plug-in slot, and the bottom assembly plate has an insertion slot that mates with the insertion plate. Both the insertion plate and the insertion slot have a third mounting screw hole through them.

[0020] It is worth noting that the third mounting screw hole is fixed by bolts, which further locks the bottom assembly plate to the door, so that the stacked boxes form a whole, distributes the weight of the top box, reduces the load pressure on the bottom box, and reduces the risk of box deformation; however, it should be noted that the third mounting screw hole should be evenly distributed to ensure that the bolts are fixed with balanced force, and avoid the bottom assembly plate from breaking due to excessive local force.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In this invention, the first and second side-mounted components are key to realizing the assembly function of the packaging boxes. The first side-mounted component is used for assembling the sides, while the second side-mounted component is used for assembling the other two sides. The combination of the two allows multiple packaging boxes to be flexibly assembled side by side. Depending on the amount of food delivered and the transportation space requirements, they can be combined into overall structures of different sizes, improving the utilization rate of transportation space and facilitating unified management and handling of multiple boxes, reducing chaos during transportation. Furthermore, the sealing box door, in conjunction with the bottom assembly plate, further enhances the assembly efficiency of the packaging box body. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To address the issue of existing technologies failing to achieve precise and stable splicing between the top, bottom, and sides of the enclosures, the following technical solution is proposed. Please refer to [link / reference]. Figure 1-5 ;

The side end of the assembly plate 306 is provided with a mating insertion hole 308 that is inserted into the insertion hole 305. A locking rod 309 is detachably connected to the outside of the insertion hole 305 and the mating insertion hole 308. A locking screw 310 is installed on the side end of the locking rod 309. The locking rod 309 passes through the insertion hole 305 and the mating insertion hole 308, and is then fixed with the locking screw 310 to form a "mechanical lock". This upgrades the assembled box from "initial fit" to "rigid connection", significantly improving the overall impact resistance. Even in the transportation environment of sudden braking and bumpy conditions, the box is not easy to separate.

[0033] The second side-mounted component includes a combination groove 401 located at the other end of the outer side of the packaging box body 1. Snap-fit ​​side blocks 402 are installed on both sides of the combination groove 401 on the side end of the packaging box body 1. A first mounting screw hole 403 is provided through the snap-fit ​​side block 402. A fitting horizontal plate 404 is installed above the combination groove 401 on the side end of the packaging box body 1. An assembly side plate 405 is installed on the side end of the packaging box body 1. A combination protrusion 406, which mates with the combination groove 401, is installed on the outer side of the assembly side plate 405. A second mounting screw hole 407 is provided inside the fitting horizontal plate 404 and at the top of the assembly side plate 405. Both sides of 405 are provided with snap-fit ​​side grooves 408 that cooperate with snap-fit ​​side blocks 402. The lower end of the bottom assembly plate 5 is provided with a plug-in bottom block 501 that fits into the plug-in groove 201. The bottom assembly plate 5 is provided with an insertion groove 502 that cooperates with the insertion plate 202. The insertion plate 202 and the insertion groove 502 are both provided with a third mounting screw hole 503.

[0034] Working principle: In use, first place the packaging box body 1 stably and open the sealed box door 2; if it needs to be combined with one side of the packaging box body 1, align the assembly protrusion 306 of the other packaging box body 1 with the assembly groove 302 in the assembly frame plate 301 of the current packaging box, so that the positioning block 303 is embedded in the positioning groove 307 to complete the initial positioning, then pass the locking rod 309 through the insertion hole 305 and the mating insertion hole 308, and tighten the locking nut 310 to fix it; if it needs to be combined with the other side of the packaging box body 1, insert the assembly protrusion 406 of the assembly side plate 405 into the other side of the packaging box body 1. The food is inserted into the combination groove 401, and the snap-fit ​​side groove 408 is aligned with the snap-fit ​​side block 402. It is then fixed to the fitting horizontal plate 404 with bolts through the first mounting screw hole 403 and the second mounting screw hole 407. If stacking is required, the bottom block 501 of the bottom assembly plate 5 of the upper packaging box is inserted into the insertion groove 201 of the lower sealing box door 2, and the insertion plate 202 is inserted into the insertion groove 502 and fixed through the third mounting screw hole 503. Finally, the food is placed into the packaging box body 1, and the sealing box door 2 is closed so that the sealing frame strip 203 is embedded in the sealing groove 101 to complete the seal.
