[0024] The following is combined with Figure 1-Figure 3 The present application is further described with reference to the following specific examples:

[0025] First of all, it should be noted that in the description of this application, if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and other directional words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of this application; in addition, if the terms "first", "second", "third" and other numerical quantifiers appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", and "connected" appear, they should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limited connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0026] like Figures 1 to 3 As shown, a packaging box includes: a box body 2, a support frame 3 and two placement plates 4, the box body 2 has a accommodating cavity 21; the support frame 3 is placed in the accommodating cavity 21, and the support frame 3 is against the four walls of the accommodating cavity 21, the support frame 3 is square, and the support frame 3 has four corners, each of which is folded inward to form an inner convex portion 31, and each inner convex portion 31 is provided with two first card grooves 311; the corners of the two placement plates 4 are respectively clamped in the two first card grooves 311, and there is a gap between adjacent placement plates 4, and a limiting hole 41 is provided on the placement plate 4.

[0027] In the present application, the box body 2 provides a receiving cavity 21 for accommodating items, which is the basic structure of the entire packaging box; the support frame 3 is placed in the receiving cavity 21, and is against the four walls of the receiving cavity 21, playing the role of supporting and fixing the internal structure. The square support frame 3 folds the four corners inward to form an inner convex portion 31, which increases the stability and functionality of the structure. A first card groove 311 is provided on the inner convex portion 31 for clamping the placement plate 4. The corners of the two placement plates 4 are respectively clamped in the two first card grooves 311, so that the placement plate 4 can be stably installed in the support frame 3. There is a gap between adjacent placement plates 4. The gap can be used to place tubular objects, such as glass bottles. After the tubular object passes through the limiting holes 41 of the two placement plates 4, the tubular object can be well positioned. This design can reduce the use of foam and still have a good protection effect.

[0028] Specifically, it further includes a supporting base plate 5 , a second card slot 312 is opened on the inner convex portion 31 , the second card slot 312 is closer to the bottom of the box body 2 , and the four corners of the supporting base plate 5 are clamped in the second card slot 312 .

[0029] The supporting base plate 5 is clamped in the second clamping slot 312, providing additional support for the bottom of the packaging box, which can better bear the weight of the placed items, especially for heavier items or when more items are placed, to prevent the items from falling out from the bottom.

[0030] Specifically, an insertion hole 32 is opened on the wall of the support frame 3, and an insertion portion 51 is provided on the support base plate 5. The insertion portion 51 can be inserted into the insertion portion 51, and the insertion portion 51 is clamped between the outer wall of the support frame 3 and the inner wall of the box body 2, and the insertion portion 51 is perpendicular to the support base plate 5.

[0031] The cooperation between the insertion portion 51 and the insertion hole 32 establishes a tighter connection between the support base plate 5 and the support frame 3. This connection method not only increases stability in the horizontal direction and prevents the support base plate 5 from shifting in the box body 2, but also further ensures the stability of the entire structure and can better cope with various external forces during transportation and handling.

[0032] Specifically, the insertion portion 51 is folded toward the bottom of the box body 2 .

[0033] When an object is placed on the supporting base plate 5 , the inserting portion 51 can be hooked at the inserting hole 32 , thereby providing a load-bearing force.

[0034] Specifically, the placement plate 4 has a limiting portion 42 facing the limiting hole 41 , and the limiting portion 42 can be folded toward the bottom of the box body 2 .

[0035] After the article is inserted into the limiting hole 41 , the limiting portion 42 can be turned downward, and the limiting portion 42 can clamp the article, thereby reducing the possibility of the article falling out of the limiting hole 41 .

[0036] Specifically, the supporting frame 3 and the supporting base plate 5 are made of cardboard.

[0037] The support frame 3 and the support base plate 5 are made of cardboard. Cardboard is a recyclable and degradable material that conforms to the concept of environmental protection. Compared with traditional foam materials, it reduces pollution to the environment and helps promote the sustainable development of the packaging industry.

[0038] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. Although this specification has described the present application in detail with reference to the above embodiments, ordinary technicians in this field should understand that technicians in the relevant technical field can still modify or replace the present application with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
