[0046] As Figures 1-6 shown, Figures 1-6 The EPS packaging box 100 provided by the first embodiment is shown. In the first embodiment, the number of the bearing extension part 22 is one. The bearing extension part 22 extends from the front end 3 to the back 4 and has a spacing with the back 4 to provide a space for the bearing extension part 22 to apply an external force.

[0047] The EPS packaging box 100 is integrally formed with the bearing extension part 22, or the bearing extension part 22 is detachably installed on the bearing part 21. The bearing extension part 22 is connected to the bearing part 21. Specifically, the bearing part 21 includes a support part 211, a first limiting part 212, and a second limiting part 213. The support part 211 is used for supporting products of different sizes, that is, the support part 211 can support the first products 200 or the second products 201. The first limiting part 212 and the second limiting part 213 are respectively connected to the two opposite sides of the support part 211, and the first limiting part 212 and the second limiting part 213 have a spacing therebetween to form a packaging space for packaging products of different sizes. The packaging space can be set to adapt to the shape of the product according to the needs of the product to be packaged. The bearing extension part 22 is connected to the side of the second limiting part 213 facing the first limiting part 212. In the first embodiment, the first limiting part 212 and the bearing extension part 22 cooperate to package and limit the first products 200.

[0048] The second limiting portion 213 is provided with a plurality of first grooves 2131 and a plurality of first protrusions 2132. The plurality of first grooves 2131 and the plurality of first protrusions 2132 alternate. The bearing extension portion 22 is connected to the first protrusion 2132 near the first limiting portion 212. Each first groove 2131 may be the same or different. Each first protrusion 2132 may be the same or different. In this application, the plurality of first grooves 2131 are the same groove, and the plurality of first protrusions 2132 are the same protrusion. This application, through the plurality of first grooves 2131 and the plurality of first protrusions 2132, can provide cushioning and shock absorption for the product packaged in the EPS packaging box 100, thereby improving the stability of the product inside the EPS packaging box 100 and making it less prone to damage.

[0049] The support extension 22 includes a first end portion 221 and a second end portion 222. The first end portion 221 faces the bottom 1. The second end portion 222 faces away from the first end portion 221. The first end portion 221 extends toward and connects to the support portion 21. The second end portion 222 has a gap with the support portion 21. In a first embodiment, the first end portion 221 extends toward the second limiting portion 213 and connects to a first protrusion 2132 near the first limiting portion 212. The second end portion 222 has a gap with the first protrusion 2132 near the first limiting portion 212. Along the direction from the front end portion 3 to the back end 4, the second end portion 222 is wider than the first end portion 221. From the first end 221 to the second end 222, the distance between the support extension 22 and the support portion 21 gradually increases, that is, the distance between the support extension 22 and the first protrusion 2132 near the first limiting portion 212 gradually increases, so that the support extension 22 gradually tilts outward from the first end 221 to the second end 222, forming a gradually expanding dividing surface, so that the user can apply external force to the support extension 22 by means of the distance between the support extension 22 and the back 4 and the gradually expanding dividing surface, thereby removing the support extension 22 from the support portion 21.

[0050] like Figures 7-9 As shown, Figures 7-9 The illustration shows the EPS packaging box 100 after the support extension 22 has been removed in the first embodiment. When the support extension 22 is removed from the support part 21, the first limiting part 212 and the second limiting part 213 cooperate to limit the second product 201. At this time, the connection between the removed support extension 22 and the first protrusion 2132 near the first limiting part 212 is flat, so that the packaging space between the first limiting part 212 and the second limiting part 213 can just fit the second product 201, while also ensuring that no burrs or protrusions that could easily damage the product are generated at the connection between the support extension 22 and the first protrusion 2132. This ensures that when the user uses the same EPS packaging box 100 to package the second product 201, which is different from the first product 200, it is not easy to damage the second product 201.

[0051] Further, the bottom 1 is provided with a plurality of second grooves 11 and a plurality of second ridges 12. The plurality of second grooves 11 and the plurality of second ridges 12 are arranged alternately. Each of the second grooves 11 can be the same or different. Each of the second ridges 12 can be the same or different. In the present application, the plurality of second grooves 11 are the same grooves, and the plurality of second ridges 12 are the same ridges. Through the plurality of second grooves 11 and the plurality of second ridges 12, the product packaged in the EPS packaging box 100 can be further provided with the buffering and shock-absorbing effect, so as to further improve the stability of the product in the EPS packaging box 100.

[0052] Further, the front end portion 3 is provided with a handgrip groove 31, so that the user can carry the EPS packaging box 100 through the handgrip groove 31. The EPS packaging box 100 further comprises a side wall between the front end portion 3 and the back portion 4, and between the top portion 2 and the bottom 1. The side wall is provided with a plurality of third grooves 51 and a plurality of third ridges 52. The plurality of third grooves 51 and the plurality of third ridges 52 are arranged alternately. Each of the third grooves 51 can be the same or different. Each of the third ridges 52 can be the same or different. In the present application, the plurality of third grooves 51 are the same grooves, and the plurality of third ridges 52 are the same ridges. Through the plurality of third grooves 51 and the plurality of third ridges 52, the product packaged in the EPS packaging box 100 can be further provided with the buffering and shock-absorbing effect, so as to further improve the stability of the product in the EPS packaging box 100. It can be understood that the first grooves 2131, the second grooves 11 and the third grooves 51 can be the same or different grooves. Correspondingly, the first ridges 2132, the second ridges 12 and the third ridges 52 can be the same or different ridges.

[0053] Please refer to Figures 10-12 , Figures 10-12 The EPS packaging box 100 provided by the second embodiment is shown. The EPS packaging box 100 provided by the second embodiment is different from the EPS packaging box 100 provided by the first embodiment in that the plurality of bearing extensions 22 in the second embodiment. Each of the bearing extensions 22 extends from the front end portion 3 to the back portion 4, and has a spacing with the back portion 4, so as to provide a space for the plurality of bearing extensions 22 to apply external force. The EPS packaging box 100 is integrated with the plurality of bearing extensions 22, or all or part of the bearing extensions 22 can be detachably mounted on the bearing portion 21.

[0054] The load bearing extension 22 near the load bearing portion 21 is connected to the load bearing portion 21 by the first end 221, and the rest of the load bearing extension 22 is connected to the adjacent load bearing extension 22 by the first end 221. In the second embodiment, the first end 221 of the load bearing extension 22 near the second limiting portion 213 extends to the second limiting portion 213 to connect to the load bearing portion 21, i.e. to connect to the first protrusion 2132 near the first limiting portion 212. The second end 222 is spaced apart from the first protrusion 2132 near the first limiting portion 212. From the first end 221 to the second end 222, the spacing between the load bearing extension 22 near the second limiting portion 213 and the first protrusion 2132 near the first limiting portion 212 gradually increases.

[0055] Correspondingly, the first end 221 of the rest of the load bearing extension 22 is connected to the first end 221 of the adjacent load bearing extension 22, and the second end 222 of the rest of the load bearing extension 22 is spaced apart from the second end 222 of the adjacent load bearing extension 22. From the first end 221 to the second end 222, the spacing between the rest of the load bearing extension 22 and the adjacent load bearing extension 22 gradually increases, so that each load bearing extension 22 gradually inclines outward from the first end 221 to the second end 222, and forms a gradually expanding partition surface between each group of adjacent load bearing extension 22, so that the user can exert an external force on one or more load bearing extension 22 by means of the spacing between the load bearing extension 22 and the back portion 4 and the gradually expanding partition surface, and then remove one or more load bearing extension 22 from the load bearing portion 21.

[0056] It can be understood that when part of the load bearing extension 22 is removed from the load bearing portion 21, or all of the load bearing extension 22 is not removed from the load bearing portion 21, the first limiting portion 212 cooperates with the load bearing extension 22 near the first limiting portion 212 to limit the first product 200. When all of the load bearing extension 22 is removed from the load bearing portion 21, the first limiting portion 212 and the second limiting portion 213 cooperate to limit the second product 201. Correspondingly, when part of the load bearing extension 22 is removed from the load bearing portion 21, the connection between the removed load bearing extension 22 and the adjacent load bearing extension 22 is flat. When all of the load bearing extension 22 is removed from the load bearing portion 21, the connection between the removed load bearing extension and the first protrusion 2132 near the first limiting portion 212 is flat.

[0057] In the above embodiments, by providing at least one load bearing extension on the EPS packaging box, and by the load bearing extension being removable from the EPS packaging box, the same EPS packaging box can be quickly adjusted to adapt to the installation requirements of products of different sizes, and products of different sizes can be installed, which reduces the number of EPS packaging boxes to be developed, significantly reduces the development cost, and also enhances the universality and adaptability of the EPS packaging box.

[0058] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.

[0059] The above is only the preferred embodiment of the present application, of course, cannot limit the scope of the present application, therefore, the equivalent changes made by the present application claims, still belong to the scope of the present application.
