DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0035] It should be noted that in the description of the present invention, the terms "front," "rear," "left," "right," "up," "down," "inside," and "outside" and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are provided solely for the purpose of facilitating the description of the present invention and do not require that the present invention be constructed or operated in a specific direction. Therefore, they should not be construed as limiting the present invention. The terms "front," "rear," "left," "right," "up," and "down" used in the description of the present invention refer to directions in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0036] This utility model provides a packaging box for use in a central channel of a front floor panel. The box is constructed by stacking several packaging box bodies in a longitudinal direction. The packaging box bodies are integrally molded from expanded polystyrene (EPS). EPS is a lightweight polymer. It is formed by adding a foaming agent to polystyrene resin and then heating it to soften it, generating gas. This creates a rigid, closed-cell foam plastic with low water absorption, excellent thermal insulation, light weight, and high mechanical strength.

[0037] like Figures 6 to 8 The figures shown are respectively a top perspective view, a bottom perspective view, and a front view of the channel in the front bottom plate in an embodiment of the present invention. The channel 3 in the front bottom plate has an overall structural shape that is convex at the top and concave at the bottom. A concave portion 33 that runs through the front and back is provided on its bottom surface. A downwardly protruding longitudinal beam 32 is provided on both sides of the concave portion 33. The outer side of the longitudinal beam 32 extends outward to form a "concave"-shaped flange 31. A plurality of outwardly protruding first limit pins 311 are provided on the bottom surface of the flange 31, and a plurality of outwardly protruding second limit pins 321 are provided on the bottom surface of the longitudinal beam 32. Three outwardly protruding clamping portions 312 are also provided on the bottom surface of the flange 31, which serve as a lateral clamping and limiting function during the installation process. A plurality of laterally distributed first reinforcing plates 331 are provided on the concave portion 33 and the longitudinal beam 32. The top surface of the channel 3 in the front bottom plate is provided with an outward-arching top protrusion 34. The top protrusion 34 is also provided with a number of transversely distributed second reinforcing plates 341. The second reinforcing plates 341 are provided with a number of outward-protruding third limiting pins 342. The first limiting pins 311, the second limiting pins 321, and the third limiting pins 342 all serve as installation limits, while the first reinforcing plates 331 and the second reinforcing plates 341 serve as structural reinforcement. A significantly upward-protruding connecting plate 343 is provided at the front end of the top protrusion 34. Figure 8 As shown in the figure, there are significant protrusions on the upper and lower end surfaces of the channel 3 in the front bottom plate, and the flange 31 has low structural strength, which can easily lead to deformation and damage when subjected to pressure during storage and transportation.

[0038] like Figures 1 to 5The figures are respectively the top perspective view, top view, bottom perspective view, bottom view, and front view of the packaging box body in an embodiment of the present invention. The top surface of the packaging box body is recessed inward to form a cavity that matches the bottom surface structure of the front bottom plate middle channel 3. The bottom surface of the front bottom plate middle channel 3 is received and fixed in the cavity with its bottom surface facing downward. In order to effectively realize the fixing function of the cavity and avoid damage to the vulnerable parts of the front bottom plate middle channel 3, the present invention adopts the following technical measures:

[0039] The mold cavity is symmetrically provided with flange support surfaces 11, longitudinal beam support surfaces 12, and recess support surfaces 13, which are distributed from the outside to the inside, and respectively match the flange 31, longitudinal beam 32, and recess 33 bottom surfaces of the front bottom plate channel 3. When the front bottom plate channel 3 is accommodated in the mold cavity, the stepped flange support surface 11 supports the bottom surface of the "concave"-shaped flange 31, the strip-shaped longitudinal beam support surface 12 supports the bottom surface of the longitudinal beam 32, and the arched recess support surface 13 supports the bottom surface of the recess 33, thereby ensuring that the front bottom plate channel 3 is evenly stressed and preventing deformation and damage to the front bottom plate channel 3 due to excessive local stress. The concave-convex structure in the mold cavity acts as a lateral limiter for the front bottom plate channel 3, and the upper packaging box body acts as a longitudinal limiter for the front bottom plate channel 3 in the lower packaging box body, thereby firmly fixing the front bottom plate channel 3 in the mold cavity.

[0040] More specifically, the flange support surface 11 and the longitudinal beam support surface 12 are recessed inward to form a clamping portion avoidance groove 122 that is compatible with the clamping portion 312. When the channel 3 in the front base plate is accommodated in the mold cavity, the clamping portion avoidance groove 122 serves to avoid and accommodate the protruding clamping portion 312. In this embodiment, there are three clamping portion avoidance grooves 122. The flange support surface 11 and the longitudinal beam support surface 12 are provided with a number of inwardly recessed avoidance grooves. The avoidance groove on the flange support surface 11 is a first avoidance groove 111, which is compatible with the first limit pin 311; the avoidance groove on the longitudinal beam support surface 12 is a second avoidance groove 121, which is compatible with the second limit pin 321. When the channel 3 in the front base plate is accommodated in the mold cavity, the first avoidance groove 111 avoids and accommodates the protruding first limit pin 311, and the second avoidance groove 121 avoids and accommodates the protruding second limit pin 321. The clamping portion avoidance groove 122 , the first avoidance groove 111 , and the second avoidance groove 121 can prevent the significantly raised portion of the bottom surface of the channel 3 in the front bottom plate from being damaged due to pressure.

[0041] More specifically, the longitudinal beam support surface 12 and the recessed support surface 13 are recessed inward to form a plurality of third avoidance grooves 131 that are compatible with the first reinforcing plate 331. When the channel 3 in the front bottom plate is accommodated in the cavity, the third avoidance grooves 131 avoid and accommodate the protruding first reinforcing plate 331. As a preferred solution, the middle area of the cavity, i.e., the majority of the recessed support surface 13, is recessed inward to form a first hollow groove 14 that penetrates the bottom surface of the packaging box body. While saving materials and reducing weight, it can also avoid conflict with the channel 3 in the front bottom plate in the lower packaging box body, i.e., the channel 3 in the lower front bottom plate is partially accommodated in the first hollow groove 14 on the bottom surface of the upper packaging box body, thereby reducing the layer height of the packaging box body and improving the utilization rate of the packaging space. Specifically, Figures 9 to 11 As shown in the figure, the top perspective view, front view, and left view of the channel in the front bottom plate of the packaging box body are respectively shown. Since the recessed support surface 13 is mostly replaced by the first hollow groove 14, only the part of the structure of the third avoidance groove 131 corresponding to the longitudinal beam support surface 12 is retained.

[0042] More specifically, the bottom surface of the packaging box body is recessed inward to form a cavity that matches the structure of the top surface of the front bottom plate middle channel 3, including a second hollow groove 21 and a plurality of fourth avoidance grooves 22. The second hollow groove 21 is adapted to the connecting plate 343. When multiple packaging box bodies are stacked, the connecting plate 343 on the top surface of the front bottom plate middle channel 3 in the lower packaging box body is precisely accommodated within the second hollow groove 21 of the upper packaging box body, avoiding airflow. The fourth avoidance groove 22 is adapted to the second reinforcing plate 341 and the third limiting pin 342. When multiple packaging box bodies are stacked, the second reinforcing plate 341 and the third limiting pin 342 on the top surface of the front bottom plate middle channel 3 in the lower packaging box body are precisely accommodated within the fourth avoidance groove 22 of the upper packaging box body, avoiding airflow. The second hollow groove 21 and the fourth avoidance groove 22 can not only prevent the second reinforcing plate 341, the third limiting pin 342 and the connecting plate 343 on the top surface of the channel 3 in the front bottom plate from being damaged due to pressure, but also reduce the layer height of the packaging box body and improve the utilization rate of the packaging space.

[0043] More specifically, the top surface of the packaging box body is provided with a number of outwardly protruding limiting posts 1, and the bottom surface of the packaging box body is recessed inwardly to form limiting grooves that are compatible with the limiting posts 1. When multiple packaging box bodies are stacked, the limiting posts 1 of the lower packaging box body are just embedded in the limiting grooves of the upper packaging box body, thereby achieving stable positioning of adjacent packaging box bodies and avoiding overturning during storage and transportation. As a preferred solution, the bottom surface of the packaging box body is provided with a material reduction groove 2 formed inwardly recessed, which plays a role in saving material and reducing weight. The aforementioned limiting groove is formed at the inner edge of the material reduction groove 2, which can not only achieve stable positioning of adjacent packaging box bodies, but also simplify the structural design of the packaging box body, thereby improving production efficiency and yield rate.

[0044] More specifically, the top surface of the packaging box body is recessed inward to form a retrieval slot 15 and a storage slot 16. The bottom surface of the packaging box body is also recessed inward to form a hand-lift slot 23. The retrieval slot 15 communicates with the mold cavity, while the hand-lift slot 23 communicates with the side of the packaging box body. Operators can smoothly lift the front bottom plate middle channel 3 within the mold cavity through the retrieval slot 15, and can smoothly lift the upper box body through the hand-lift slot 23 between two adjacent packaging boxes, thereby improving work efficiency. The storage slot 16 is used to store accessories in the front bottom plate middle channel 3, avoiding the problem of mismatch caused by the independent storage and transportation of accessories.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
