[0033] Reference Figure 1-6 As shown, the utility model is a paper cushioning packaging structure for refrigerators, comprising a top cover 3, wherein the top cover 3 comprises a first sand tube paper frame 30 and a first honeycomb paperboard 31, wherein four corners of the first honeycomb paperboard 31 are provided with reserved holes and are bonded in the first sand tube paper frame 30 to form a box body with an opening, wherein the first sand tube paper frame 30 is composed of a sand tube paper corner guard that is slotted, punched, folded and enclosed, and can play a positioning role and has good impact resistance; a bottom support 5, wherein the bottom support 5 comprises a second sand tube paper frame 50, a second honeycomb paperboard 51, a third honeycomb paperboard 52 and a filling paperboard, wherein the second honeycomb paperboard 51 The four corners are provided with reserved slots and glued into the second sand tube paper frame 50, which are used to lift the refrigerator 2 to be packaged as a whole to form a bottom buffer space. The second sand tube paper frame 50 has the same structure as the first sand tube paper frame 30. The third honeycomb paperboard 52 is glued to the second honeycomb paperboard 51 to support the bottom surface of the refrigerator 2. The filling paperboard is glued to the second honeycomb paperboard 51 to fill the suspended part of the bottom of the refrigerator 2; the supporting paper corner protector 4 is provided with a plurality of reserved holes that respectively penetrate the first honeycomb paperboard 31 and the reserved slots of the second honeycomb paperboard 51, which are used to improve the compression and impact resistance of the packaging structure.

[0034] Embodiment 2

[0035] Reference Figure 1-6 As shown, based on the technical solution of the first embodiment, a paper cushioning packaging structure for a refrigerator, for the specific structural design of the top cover 3, as shown in FIG. Figure 5 As shown, the first sand tube paper frame is composed of three second sand tube paper corner protectors 301, the first sand tube paper corner protectors 300 and the third sand tube paper corner protectors 302. Specifically, the first sand tube paper corner protector 300, the three sequentially connected second sand tube paper corner protectors 301 and the third sand tube paper corner protectors 302 are an integrated structure obtained by slotting and punching a sand tube paper corner protector. Figure 5 As shown, the first sand tube paper frame 30 is obtained by slotting and punching a sand tube paper corner guard before molding. After being processed, multiple sand tube paper corner guards can be folded to form a rectangular frame, which serves as a container for adding other materials and plays a positioning role when assembling the top cover 3 and the bottom bracket 5. After the first sand tube paper frame is molded, the internal folded edges are closely connected and support each other, and have good impact resistance.

[0036] Furthermore, the length and width of the first honeycomb paperboard 31 are consistent with the internal dimensions of the first sand tube paper frame, and the reserved holes of the first honeycomb paperboard 31 are used to insert the support paper corner guard 4 and the top door hinge of the refrigerator 2. Specifically, Figure 4As shown, there are four reserved holes, including a larger first reserved hole 311 and three smaller second reserved holes 312. The first reserved hole 311 is used to avoid the top door hinge of the refrigerator 2, and also leaves a position for inserting the supporting paper corner protector 4. The second reserved hole 312 is only used for inserting the supporting paper corner protector.

[0037] As for the specific structural design of the top cover 3, Figure 6 As shown, the length and width of the second honeycomb paperboard 51 match the internal dimensions of the second sand tube paper frame, the reserved slots of the second honeycomb paperboard 51 are used to insert the supporting paper corner protector 4, and four reserved slots are provided. The side of the third honeycomb paperboard 52 is provided with a reserved space for avoiding the front adjustment foot and the bottom door hinge of the refrigerator 2. Specifically, there are two reserved spaces, including a first reserved space 531 with a larger size and a second reserved space 532 with a smaller size. The first reserved space 531 is designed to avoid a front adjustment foot and the bottom door hinge of the refrigerator 2, and the second reserved space 532 is designed to avoid another front adjustment foot of the refrigerator 2.

[0038] Furthermore, the filling paperboard includes a fourth honeycomb paperboard 53 and a fifth honeycomb paperboard 54. The fourth honeycomb paperboard 53 is located in the reserved space of the third honeycomb paperboard 52 to support the front adjustment foot of the refrigerator 2. Specifically, there is a drop space between the first reserved space 531 and a front adjustment foot of the refrigerator 2 and the bottom door hinge. Since the height of the adjustment foot of the refrigerator 2 is higher than the door hinge, the fourth honeycomb paperboard 53 is placed to increase the force bearing area and improve the compression resistance of the packaging structure. In addition, the fifth honeycomb paperboard 54 is bonded to the end of the second honeycomb paperboard 51 to support the chassis of the refrigerator 2. When the refrigerator 2 is placed on the bottom structure, it will bear pressure on the chassis of the relatively hard component of the refrigerator 2 and fill the drop space below the height of the chassis behind the refrigerator 2. The length or width of the third honeycomb paperboard 52 is smaller than that of the second honeycomb paperboard 51. At the same time, the third honeycomb support plate is just installed in the internal cavity of the second honeycomb paperboard 51 along its own length or width direction.
