[0042] As attached Figure 1 As shown, the cabinet opening structure in this embodiment includes four cabinet opening frames, two of which are long frames 10 and two are short frames 20. Adjacent long frames 10 and short frames 20 are beveled at both ends at a 45° angle and joined end-to-end to form a rectangular frame structure. The long frames 10 and short frames 20 have the same structure, both being stepped structures, as shown... Figure 2 As shown, in this embodiment, Figure 1 Taking the structure of the long frame 10 on the left side as an example, the structure of the cabinet frame includes:

[0043] The outer panel assembly includes a first outer panel 11 and a second outer panel 12, wherein the first outer panel 11 and the second outer panel 12 are arranged in parallel and offset in the vertical direction.

[0044] A connecting plate 13 is used to connect the edges of the first outer panel 11 and the second outer panel 12, and the connecting plate 13 is perpendicular to the first outer panel 11 and the second outer panel 12.

[0056] In the installation of the low-temperature insulation box of the embodiment, the side edge reinforcing plate 50 on the long side frame 10 is installed first, and then the long side frame 10 and the short side frame 20 are bonded together, and then the L-shaped cabinet opening connecting piece 60 is installed in the first clamping groove 113, the second clamping groove 114 and the third clamping groove 115, so as to increase the connecting strength, make the butt joint of the two side frames connect firmly, prevent the cabinet opening structure from cracking when being connected with the inner container 30, and prevent the inner container from falling off after the inner container is installed in the cabinet opening component. The inner container reinforcing piece 31 around the inner container 3 is attached to the reinforcing piece fixing edge 152, and is fixed firmly by using self-tapping nails, so as to prevent the inner container from falling off. After the inner container is connected with the cabinet opening structure firmly, the whole is installed into the box shell 40, and the box shell stop edge 11 can ensure that the cabinet opening structure is smoothly slid into the box shell 40 and that the box shell 40 is not detached after being slid in.

[0057] Based on the above technical scheme, the cabinet opening structure of the utility model inserts the inner container edge into the inner container clamping groove, and the reinforcing body fixing edge of the inner container fixing piece is fixed with the inner container reinforcing iron through a screw, so as to prevent the inner container from falling off, and hot melt adhesive is not needed, which is safe and reliable, reduces the risk of personnel operation, the box shell stop edge can prevent the box shell from falling off, and the cabinet opening structure is connected firmly and reliably as a whole.

[0058] The setting of the cabinet opening connecting piece can increase the connecting strength of the two adjacent cabinet opening side frames, and prevent the cabinet opening side frame from cracking when being connected with the inner container.

[0059] The setting of the first clamping groove, the second clamping groove and the third clamping groove increases the bonding area of the foaming material, reduces the risk of foaming material overflow, and to some extent, increases the bonding strength of the cabinet opening structure and the inner container, and improves the firmness of the connection between the inner container and the cabinet opening structure.
