In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0015] The refrigerator box panels include a bottom panel, a front panel, two side panels, and a top panel. The connection method of the refrigerator box panels is that the side panels press the bottom panel, the side panels and the bottom panel clamp the front panel, and the top panel presses the front panel and the side panels. The connections between all panels adopt the built-in connection structure of the utility model. Since the connection methods between the panels are basically the same, only the built-in connection structure between the bottom panel and the side panel is used as an example to describe the structure, and the connection methods between other panels are not repeated here.

[0016] like Figure 1 and Figure 2 As shown, a split refrigerator box panel built-in connection structure is used to fix the vertically connected side panel 10 and bottom panel 20, the bottom end surface of the side panel 10 is butted against the upper surface of the bottom panel 20 near the end position, and the side panel 10 is flush with the outer surface of the bottom panel 20.

[0017] The side panel 10 and the bottom panel 20 both include an internal insulation layer and a metal plate coated on the outside of the insulation layer. The side panel 10 and the bottom panel 20 are not provided with a metal plate at the docking position, but the two insulation plates are directly docked, and non-docking positions are provided with metal plates for protection, that is, the insulation layer of the side panel 10 and the insulation layer of the bottom panel 20 are docked and plugged together at the docking position. The docking surfaces and plug-in surfaces of the two insulation layers are bonded and fixed by a connecting adhesive layer 30. The inner connecting corners of the side panel 10 and the bottom panel 20 are fixed by a connecting angle steel 40, and the connecting angle steel 40 is connected to the outside of the metal plate.

[0018] The bottom end surface of the side plate 10 is provided with an outwardly protruding plug-in protrusion 11 , and the upper surface of the bottom plate 20 is provided with an inwardly recessed plug-in groove 21 near the end, and the plug-in protrusion 11 is correspondingly plugged and matched with the plug-in groove 21 .

[0019] Rigid connectors are embedded in the bottom plate 20 and the side plate 10 at positions corresponding to the connecting angle steels 40 . The connecting angle steels 40 are connected to the corresponding rigid connectors via rivets 50 . The rigid connectors are aluminum alloy square tubes 60 embedded in the bottom plate 20 and the side plate 10 .

[0020] The working principle of this embodiment is:

[0021] During processing, a plug-in protrusion 11 protruding outward is processed at the end of the side panel 10, and an aluminum alloy square tube 60 is embedded inside, and a plug-in groove 21 recessed in the box is processed near the end of the upper surface of the bottom plate 20, and an aluminum alloy square tube 60 is embedded inside; during plug-in installation, the bottom end surface of the side panel 10 is in contact with the upper surface of the bottom plate 20, and the plug-in protrusion 11 of the side panel 10 is correspondingly inserted into the plug-in groove 21 of the bottom plate 20, and before docking, a layer of connecting adhesive layer 30 is coated on the docking surface and the plug-in surface. After the plug-in is completed, the docking surface and the plug-in surface are bonded and fixed by the connecting adhesive layer 30. After the docking is completed, the outer surface of the side panel 10 is flush with the outer end surface of the bottom plate 20; then a connecting angle steel 40 is placed at the inner connecting corner of the bottom plate 20 and the side panel 10, and the connecting angle steel 40 is fixed to the corresponding aluminum alloy square tube 60 by a rivet 50, that is, the connection between the side panel 10 and the bottom plate 20 is completed.

[0022] The connection form of the utility model is that protrusions and grooves are processed on each box plate respectively, so that the connection of the box plates forms a plug-in fit, and resin glue is used for bonding. There is no need to fill the gap with other materials, reduce the number of parts bonded with glue, and ensure the reliability of bonding. The joint is overlapped by the insulation materials of each box plate, so it does not affect the insulation performance. At the same time, the self-processed groove can ensure that the joint gap between the two box plates is small, and only glue is used to fill the gap, and the bonding is firm. In addition, angle irons are arranged inside the box body, and rivets 50 are used to fix the two box plates inside, and the rivets 50 are not exposed, which is beneficial to the appearance and shape, ensuring the integrity of the appearance of the box body, and rigid connectors are embedded inside the box plate to ensure that the connection stability between the box plates is improved, the connection is firm, the reliability is better, and it is beneficial to the development of new shapes for cold storage boxes.
