Description

Technical Field

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

[0002] Packaging boxes are used to package goods for storage and transportation. Currently, commonly used packaging boxes consist of a box body and a lid, both made of plastic. One side of the lid is hinged to the box body, while the other side is hinged with a snap fastener for locking. In actual use, due to the stacking of multiple boxes, this structure is prone to deformation under impact and gravity, leading to snap fastener failure and the risk of the lid opening unexpectedly. Furthermore, when transported to high-altitude areas, the reduced external air pressure can cause the boxes to bulge due to pressure differential, resulting in poor stability when stacked.

[0003] Therefore, designing a packaging box with high structural strength that meets the transportation needs of different environments is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a packaging box with a simple structure and high structural strength, which can meet the needs of stacking and transportation in different environments.

[0005] The technical solution of this utility model is as follows: a packaging box, including a box body and a box lid. The box body has a rectangular box-shaped structure, with one end open and the other end closed. The side wall of the box body near the open end is provided with a circumferentially surrounding snap-fit ​​flange. The top surface of the box body is provided with two longitudinal ribs extending along the length direction and spaced apart. The top surface of the box body is provided with multiple positioning bosses, which are located between the two longitudinal ribs and spaced apart along the length direction. The bottom surface of the box body is provided with multiple positioning grooves, which correspond to the positioning bosses on the top surface. Both sides of the box body are provided with multiple transverse ribs, which are spaced apart along the length direction. The two ends of the transverse ribs extend to the positioning grooves and positioning bosses, respectively. At least one side of the box body is hinged with a handle, located between two adjacent transverse ribs. The four sides of the box lid are each hinged with at least one buckle. The box lid is closed at the open end of the box body and is fastened to the snap-fit ​​flange by the buckles, forming a detachable connection.

[0006] The other end of the box is sealed off by a bottom plate.

[0007] The other end of the housing is provided with a circumferential mounting flange. The base plate is connected to the mounting flange by multiple bolts and threaded nuts to form a detachable connection.

[0008] Multiple first auxiliary longitudinal ribs are provided between the transverse rib and the mounting flange near the other end of the housing. Multiple second auxiliary longitudinal ribs are provided between the positioning boss and positioning groove and the mounting flange near the other end of the housing. Multiple third auxiliary longitudinal ribs are provided between the transverse rib and the snap-fit ​​flange near one end of the housing. Multiple fourth auxiliary longitudinal ribs are provided between the positioning boss and positioning groove and the snap-fit ​​flange near one end of the housing.

[0009] The two adjacent positioning slots are connected by a reinforcing mesh, which is integrally formed on the bottom surface of the box.

[0010] Each side of the box has two hinged handles, which are symmetrically distributed.

[0011] A sealing ring is provided on the closing surface of the box lid, which is adapted to the contour of the open end of the box body.

[0012] The box cover is equipped with a pressure regulating valve.

[0013] The above technical solution has the following beneficial effects:

[0014] 1. The packaging box includes a box body and a box lid. The box body has a rectangular box-shaped structure, with one end open and the other end closed. The open end serves as the box opening, and the closed end serves as the box bottom. A circumferentially surrounding snap-fit ​​flange is provided on the side wall of the box body near the open end. This flange strengthens the structural strength of the box body and also serves as the fastening point for the lid's latches. Two longitudinal ribs extending along the length of the box body are provided on the top surface of the box body, spaced apart. These ribs further enhance the structural strength of the box body. Multiple positioning bosses are provided on the top surface of the box body. These positioning bosses are located between the two longitudinal ribs and are spaced apart along the length of the box body. These positioning bosses serve both as overlapping points when the packaging boxes are stacked / transported and as reinforcement of the box body's structural strength. The bottom surface of the box has multiple positioning grooves, which correspond to positioning bosses on the top surface. When the boxes are stacked / transported, the positioning grooves on the bottom surface of the upper box cooperate with the positioning bosses on the top surface of the lower box to ensure the stability of the stacked boxes. The positioning grooves also enhance the structural strength of the box. Multiple transverse ribs are provided on both sides of the box, spaced apart along its length. The ends of the ribs extend to the positioning grooves and positioning bosses, respectively. These ribs, in conjunction with the longitudinal ribs, positioning grooves, and positioning bosses, improve the overall structural strength of the box and also act as protective ribs, reducing the risk of scratches and cuts. A handle is hinged to at least one side of the box, located between two adjacent transverse ribs, for handling. At least one latch is hinged to each of the four sides of the lid, using conventional fasteners. The lid closes at the open end of the box and is secured to the snap-fit ​​flange via the latches, forming a detachable connection that meets the requirements for closed use. The latches are reliable and provide good serviceability.

[0015] 2. The other end of the box is closed by the bottom plate, which makes it easy to process the box and the bottom plate separately, reducing the processing difficulty and cost. The other end of the box is provided with a mounting flange that surrounds the circumference. The bottom plate is connected by multiple bolts passing through the mounting flange and threaded nuts, forming a detachable connection. This connection method is simple, stable and reliable.

[0016] 3. Multiple first auxiliary longitudinal ribs are provided between the transverse ribs and the mounting flange near the other end of the box body. Multiple second auxiliary longitudinal ribs are provided between the positioning boss and positioning groove and the mounting flange near the other end of the box body. Multiple third auxiliary longitudinal ribs are provided between the transverse ribs and the snap-fit ​​flange near one end of the box body. Multiple fourth auxiliary longitudinal ribs are provided between the positioning boss and positioning groove and the snap-fit ​​flange near one end of the box body. These auxiliary longitudinal ribs not only improve the structural strength of the box body, but also protect the buckles, effectively improving the stability and service life of the packaging box.

[0017] 4. The lid is equipped with a pressure regulating valve, which can be used to adjust the internal pressure of the chamber as needed to keep it consistent with the external pressure and meet the usage requirements at different altitudes.
