[0002] At present, large plastic airtight packaging boxes are mainly composed of a box body and a box cover on the top of the box body. The box body and the box cover are both manufactured by rotational molding. The box wall of the box body is usually provided with a rotationally molded embedded part, the purpose of which is to install various auxiliary accessories such as a meter valve or a lifting ring or a hanger on the embedded part later; however, traditional embedded parts are only a tubular main body, which is mainly rotationally molded with the box body through a knurled shape or a hexagonal shape. During the manufacturing process, this shape will result in the rotational molding material not wrapping the embedded part tightly enough, resulting in poor fastening between the embedded part and the rotationally molded box body. Therefore, when installing various auxiliary accessories, the embedded part is often easily driven to form radial rotation or axial movement, resulting in loose position, that is, the anti-rotation performance and tensile performance of the embedded part are poor, which not only causes the sealing leakage between the embedded part and the box body, but also affects the installation effect of various auxiliary accessories. At the same time, many installation interfaces or installation joints of embedded parts will protrude on the outer surface of the box, that is, the installation location of the embedded parts will directly protrude, which is easy to be damaged by bumps during the movement of the plastic airtight packaging box, thereby affecting the subsequent installation of auxiliary accessories.

[0026] A pre-embedded parts fastening type plastic airtight packaging box, such as Figure 1~Figure 5 As shown, it is mainly used for airtight storage of articles, and its structure includes a box body 1 and a box cover 2 covering the top of the box body, etc. The box body 1 and the box cover 2 are both made of rotational molding material through a rotational molding process.

[0027] The outer surface of the box body 1 and the outer surface of the box cover 2 are both provided with a plurality of reinforcement grooves, and each adjacent reinforcement grooves may be separated by a reinforcement rib. A plurality of reinforcement ribs are also provided on the top surface of the box cover 2. Handles 7 are provided in several of the reinforcement grooves on the outer surface of the box body 1 to facilitate the movement of the airtight packaging box. A plurality of hinges 6 and a plurality of locks 3 are provided between the box body 1 and the box cover 2. The plurality of hinges 6 only need to be provided on one of the side surfaces so that the box cover 2 can form a single-sided opening and closing connection relative to the box body 1, and a plurality of locks 3 are provided on the remaining side surfaces to achieve locking.

[0028] The outer surface of the box body 1 is also provided with a circular recessed groove 11 , which extends into the box body and is rotationally molded to wrap the embedded part 5 to form a protrusion 12 .

[0029] The embedded part 5 is composed of a tubular main body 51 and a connecting piece 52 connected to the tail of the main body. The front part of the main body 51 is provided with a connecting hole 53 exposed from the inside and outside of the sink 11, and the connecting hole is an internal threaded hole. It can be designed as a through hole passing through the axis of the main body 51 or a blind hole according to actual use needs. Various auxiliary accessories such as a gauge valve 4 or a lifting ring or a pendant can be installed in the connecting hole according to actual use needs.

[0030] A plurality of reinforcement grooves 511 are arranged on the outer circumferential surface of the main body 51 . The plurality of reinforcement grooves are arranged equidistantly along the axial direction, and each reinforcement groove 511 is a trapezoidal annular groove surrounding along the radial direction.

[0031] The connecting piece 52 is provided with a plurality of holes 521. Specifically, the connecting piece 52 is a circular sheet with a diameter larger than the outer diameter of the main body 51. The plurality of holes 521 are evenly distributed on the connecting piece 52 with the axis of the main body 51 as the circumference. Each hole 521 is a circular hole.

[0032] In this way, the convex portion 12 is formed by extending from the sink 11 into the box body 1 and roto-molding the embedded component 5, so that the roto-molding manufacturing between the embedded component 5 and the box body 1 can be achieved.

[0033] At the same time, the raised portion 12 is rotationally molded and wrapped around the connecting piece 52 of the embedded part 5, so that the rotationally molded material can flow and fill the several form holes 521 at the same time to form an integrated wrapping structure, and can also form a mushroom head shape on the inner surface of the box body 1. The advantage of such a structure is that the anti-rotation performance and tensile performance of the embedded part 5 can be better improved by using the connecting piece 52 with several form holes 521 and combining with the mushroom head shape on the inner surface of the box body 1. The raised portion 12 is rotationally molded and wrapped around the main body 51 of the embedded part 5, and the rotationally molded material can flow and fill the several reinforcement grooves 511 at the same time to form an integrated wrapping structure, which can also better improve the tensile performance of the embedded part 5.

[0034] Obviously, through this unique embedded part 5 structure and the special design made by rotational molding of the box body 1, the connection between the embedded part 5 and the box body 1 can be made tighter, and the position will not become loose even if it is rotated or pulled during installation of auxiliary accessories, thereby effectively ensuring the sealing performance between the embedded part 5 and the box body 1 and improving the installation effect of various auxiliary accessories; in addition, the connecting hole 53 on the front of the main body 51 is exposed from the inside and outside of the sink 11, instead of directly protruding from the outer surface of the box body in the traditional structure, which can protect the installation place of the embedded part 5 from being easily bumped and damaged.
