A buckle type freezer liner, comprising a bottom plate and a coaming plate, the bottom plate includes at least four long sides of the bottom plate, two adjacent long sides of the bottom plate are connected by arc edges of the bottom plate, the coaming plate includes The sides correspond to the long sides of the coaming boards, and the long sides of the adjacent two coaming boards are connected by the arc edges of the coaming boards. The edge of the flanging is folded again to the inner side of the inner tank to form a U-shaped groove with the opening facing downward. Inside, the arc edge of the bottom plate is folded upwards, perpendicular to the plane where the bottom plate is located, the arc edge of the coaming plate extends into the inner side of the arc edge of the bottom plate, the arc edge of the coaming plate abuts against the bottom plate and is in contact with the bottom plate The arc edge of the bottom plate is closely fitted.

Further, both sides of the long side of the bottom plate are hypotenuses, and the long side of the bottom plate is connected to the arc edge of the bottom plate through the hypotenuse.

Further, the end of the hook edge abuts against the bottom of the U-shaped groove.

Further, the arc edge of the bottom plate is turned upward by 90° through a stretching process.

The height of the arc edge of the bottom plate is not greater than the groove height of the U-shaped groove.

Compared with the prior art, the advantages and positive effects of the utility model are: the buckle type freezer liner of the utility model adopts a buckle-joint structure between the long side of the bottom plate and the long side of the coaming plate, ensuring that the bottom plate of the liner is The connection strength between the two adjacent bottom plates is connected by the arc edge of the bottom plate, and the arc edge of the bottom plate is turned up 90°, forming a gallbladder angle together with the arc edge of the fence plate. This gallbladder angle structure does not require manual work. It is knocked and fixed, so it will not be deformed and flashed. It adopts an arc-shaped structure design, with a smooth transition at the corners, and the appearance of the liner is more refined. In addition, the corners of the liner include the arc edge of the inner wall and the outer edge of the wall, which is double Layer structure helps to increase strength.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment 1. This embodiment proposes a snap-fit type freezer liner, as shown in FIG. 1 , including a bottom plate 11 and a surrounding plate 12. As shown in FIG. 2 , it is a schematic diagram of the corner structure when the bottom plate 11 is deployed. It includes at least four long sides 111 of the bottom plate, and two adjacent long sides 111 of the bottom plate are connected by arc edges 112 of the bottom plate. As shown in FIG. The long side of the coaming corresponding to each other, as shown in Figure 5, is a cross-sectional view of the corner after the bottom plate 11 and the coaming 12 are assembled, and the two adjacent long sides of the coaming are connected by the arc edge 122 of the coaming , as shown in Figure 4a, is a partial longitudinal sectional view of the base plate 11, the base plate long side 111 has an upward flange 111a, the flange 111a is perpendicular to the plane where the base plate 11 is located, and the edge of the flange 111a is turned over again to the inside of the inner container, Form the U-shaped groove 111b with the opening facing downward, as shown in Figure 4b, which is a partial longitudinal sectional view of the enclosure 12, and the long side of the enclosure is turned over to the outside of the inner tank to form a hook edge 121, as shown in Figure 4c, which is the length of the enclosure 121. Schematic diagram of the assembly of the side and the long side of the bottom plate, the hook edge 121 extends into the U-shaped groove 111b, the arc edge 112 of the bottom plate is folded upwards, and is perpendicular to the plane where the bottom plate 12 is located, and the arc edge 122 of the hoarding plate extends into the inner side of the arc edge 112 of the bottom plate , the arc edge 122 of the shroud abuts against the bottom plate 12 and is in close contact with the arc edge 112 of the bottom plate. The buckle type freezer liner of this embodiment adopts a buckle structure by adopting a buckle-type structure between the long side of the bottom plate and the long side of the coaming, which ensures the connection strength between the bottom plate and the coaming of the inner tank, and is not easy to come off. The long sides of the bottom plate are connected by the arc edge of the bottom plate, and the arc edge of the bottom plate is turned up 90° to form a bile angle together with the arc edge of the coaming plate. Moreover, the connection strength is reliable. Therefore, there is no need to manually beat and fix the corner structure of the gallbladder. The two can be spliced, so there will be no deformation and flash seams. Fine, in addition, the bile angle includes the arc edge of the inner panel and the arc edge of the outer panel, which is a double-layer structure, which helps to improve the strength, and the moisture vapor is not easy to enter the foam layer of the liner from the seam.

As shown in FIG. 2 , the two sides of the long side 111 of the bottom plate are hypotenuses 111c, and the long side 111 of the bottom plate is connected to the arc edge 112 of the bottom plate through the hypotenuse 111c. In this kind of structure, after the coaming plate 12 is connected with the base plate 11, a section of oblique shoulder overlaps with the arc edge on the long side, and there is no flash joint between the two.

As shown in Figure 4c, the end of the hook edge 121 is preferably in contact with the bottom of the U-shaped groove 111b, which further stabilizes the connection reliability between the bottom plate and the enclosure. When moving the enclosure, the hook edge 121 hooks And support the groove bottom of the U-shaped groove, and then drive the supporting bottom plate to move together with the coaming plate as a whole.

Preferably, in this embodiment, the arc edge 112 of the bottom plate is folded upward by 90° through a stretching process, which can reduce the wrinkles of the arc edge 112 of the bottom plate, and further reduce flash seams at the corners of the gallbladder.

In order to further improve the stability of the connection between the shroud and the bottom plate, the height of the arc edge 112 of the bottom plate is not greater than the height of the U-shaped groove 111b.
