Technical Field

[0001] This utility model relates to the field of paper food packaging box technology, and in particular to a paper food packaging box structure. Background Technology

[0002] Paper food packaging boxes are boxes made of paper materials used to package and protect food. They are commonly used for various types of food, such as snacks, candy, beverages, and fast food. Paper packaging boxes are environmentally friendly, recyclable, and biodegradable, and have gained increasing attention in recent years.

[0003] For example, Chinese utility model patent application number CN202321526539.1 discloses a paper food packaging box with an anti-collision structure, including a box body, a central rod fixed at the center of the box body, a reinforcing frame fitted on the outer wall of the central rod, a reinforcing side plate fixed on the side wall of the reinforcing frame, a slot on the side wall of the central rod, and an assembly groove on the inner wall of the reinforcing frame. A locking block is set inside the assembly groove, and one end of the locking block is placed inside the slot. This utility model, through the design of the central rod, reinforcing frame, reinforcing side plate, locking block, and slot, fits the reinforcing frame onto the central rod, and fixes its position by locking the locking block into the slot. At this time, the reinforcing frame is placed on the four inner surfaces of the box body, cooperating with the reinforcing side plate to support and reinforce the box body, preventing it from deforming due to impact, and has an anti-collision effect.

[0004] The above solution has the following shortcomings: In actual use, although the solution supports and reinforces the cardboard box by installing a reinforcing frame and reinforcing side panels inside the cardboard box to prevent the cardboard box from deforming due to impact, it does not set up a protective structure on the outside of the cardboard box, making the cardboard box easy to come into direct contact with external objects, resulting in the cardboard box breaking or being damaged, thus affecting the protective effect of the paper food packaging box. Utility Model Content

[0007] By setting up snap-fit ​​components and cooperating with moving components and protrusions, four vertical plates can be installed around the perimeter of the box and contact the four sides of the box, while four top plates are installed on the top of the box and contact the tops of the two folding lids, thereby protecting the exterior of the box.

[0008] As a further description of the above technical solution:

[0009] The mounting assembly includes four mounting ports on the bottom of the mounting plate, and a damping shaft is rotatably connected between the two sides of the inner wall of each of the four mounting ports. A connecting strip is rotatably connected to the outside of the damping shaft.

[0010] By setting a damping shaft and using connecting strips, the vertical plate can be easily moved away from the four sides of the box, thereby allowing the top plate to be moved away from the top of the box, making it easy to open the box.

[0011] As a further description of the above technical solution:

[0012] The top of the connecting strip is fixedly connected to the bottom of the vertical plate.

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.

[0034] Reference Figure 1-5This utility model provides a paper food packaging box structure, including a box body 1. A mounting plate 2 is fixedly connected to the bottom of the box body 1. A mounting assembly is provided at the bottom of the mounting plate 2. Four vertical plates 3 are provided at the top of the mounting assembly. A top plate 4 is fixedly connected to one side of each of the four vertical plates 3 that is attached to the box body 1. A connecting post 5 is fixedly connected to the top of one of the top plates 4. A snap-fit ​​assembly is provided at the bottom of the connecting post 5. Movable assemblies are provided at the top of the other three top plates 4. A protrusion 6 is provided at the top of each movable assembly. A pusher strip 7 is fixedly connected to one side of each protrusion 6. The top of the box body 1... The rotating connection has two folding lids 16. The top of the box body 1 is square, the top plate 4 is triangular, and the size of the four top plates 4 is the same as the top of the box body 1. The bottom of the top plate 4 fits into the top of the two folding lids 16. The connecting post 5 is circular. By setting a snap-fit ​​component and cooperating with the moving component and the protrusion 6, the four vertical plates 3 can be installed around the box body 1 and contact the four sides of the box body 1. At the same time, the four top plates 4 can be installed on the top of the box body 1 and contact the top of the two folding lids 16, thereby protecting the outside of the box body 1.

[0035] The mounting components include four mounting openings 8 at the bottom of the mounting plate 2. A damping shaft 9 is rotatably connected between the two sides of the inner wall of each of the four mounting openings 8. A connecting strip 10 is rotatably connected to the outside of the damping shaft 9. The top of the connecting strip 10 is fixedly connected to the bottom of the vertical plate 3. The bottom of the connecting strip 10 is semi-circular. By setting the damping shaft 9 and cooperating with the connecting strip 10, the vertical plate 3 can be easily moved away from the four sides of the box 1, thereby allowing the top plate 4 to be moved away from the top of the box 1, making it easy to open the box 1.

[0036] The snap-fit ​​assembly includes three limiting ports 11 fixedly connected to the bottom of the connecting post 5. The top of the inner wall of each of the three limiting ports 11 is provided with a fixing port 12. The diameter of the fixing port 12 is the same as the diameter of the top of the protrusion 6. After the four vertical plates 3 are attached to the four sides of the box body 1, the three limiting ports 15 are located above the three top plates 4 on which the moving components are installed.

[0037] The moving component includes a hollow block 13 fixedly connected to the top of the top plate 4. A spring 14 is fixedly connected to the bottom of the inner wall of the hollow block 13. A limiting opening 15 is opened on one side of the inner wall of the hollow block 13. The top of the spring 14 is fixedly connected to the bottom of the protrusion 6. One side of the push bar 7 passes through the limiting opening 15 and extends to the outside of the hollow block 13. By setting the spring 14, it can be ensured that the protrusion 6 always passes through the fixing opening 12.

[0038] Working principle: After sealing the box 1, the operator rotates three of the vertical plates 3, each equipped with a hollow block 13, ninety degrees, so that one side of these three vertical plates 3 is in contact with the outside of the box 1, and the corresponding top plate 4 abuts against the top of the folding lid 16. At this time, the three push bars 7 are pushed, causing the three protrusions 6 to move downwards and compress the spring 14 until the protrusions 6 are completely retracted into the interior of the hollow block 13. Then, another vertical plate 3 is rotated ninety degrees and brought into contact with the outside of the box 1. At this time, the positions of the three fixing holes 12 on the connecting post 5 are aligned with the positions of the three protrusions 6. Then, the three protrusions 14 are released. The push bar 7, under the pushing force of the three springs 14, causes the three protrusions 6 to move upward and pass through the three fixing holes 12 respectively, fixing the connecting post 5, thereby fixing the four vertical plates 3 and the four top plates 4 to the outside of the box body 1, thus protecting the outside of the box body 1. If the box body 1 needs to be opened later, simply pull the three push bars 7 to make the protrusions 6 move downward and disengage from the fixing holes 12, releasing the fixing of the connecting post 5. Then, first lay the vertical plate 3 with the connecting post 5 flat, and then lay the other three vertical plates 3 flat, so that the four top plates 4 can be removed from the top of the box body 1, making it easy to open the box body 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
