[0030] The second fold 202 is arranged to reduce additional connecting structures and provide support strength for the cover plate 103. In order to improve the appearance and connection strength, the second fold 202 in the embodiment is arranged on the outer side of the side plate 106, and covers the inner lining plate 102 and the side plate 106. The second fastening part 403 is arranged to fix the first fold 302, the second fold 202 and the side plate 106 together, thereby simplifying the fastening step. The second fastening part 403 can be a screw, a rivet, a buckle or the like.

[0031] Further, as shown in Figures 3-4 , the upper edge of the side plate 106 is provided with a third fold 402 folded inwardly, the inner lining plate 102 is limited below the third fold 402, and the bottom surface of the cover plate 103 abuts against the third fold 402.

[0032] The bottom of the rear side of the inner lining plate 102 is fixed by the first fixing structure 201, the top of the inner lining plate 102 is limited by the third fold 402, and finally the front end of the inner lining plate 102 is fixed by the second fixing structure 301, thereby achieving the preliminary installation and fixation of the inner lining plate 102; the cover plate 103 is installed on the third fold 402, and the third fold 402 widens the contact area between the side plate 106 and the cover plate 103, thereby improving the assembly stability.

[0033] In some embodiments, as shown in Figure 2 , 3 , 4, the first fixing structure 201 includes a fourth fold 404 arranged on the upper edge of the back plate 107 and folded downwardly, and the bottom of the inner lining plate 102 abuts against the fourth fold 404.

[0034] The fourth fold 404 is part of the back plate 107, which does not need to additionally increase the accessories, thereby reducing the complexity of the structure. The fourth fold 404 can be integrally folded when the back plate 107 is manufactured, thereby simplifying the production process. In the embodiment, the inner lining plate 102 is directly placed on the fourth fold 404 during installation, and is connected with the side plate 106 by the second fixing structure 301, thereby facilitating the installation and disassembly of the inner lining plate 102 and simplifying the operation.

[0035] In some embodiments, as shown in Figure 3 , the back plate 107 includes a side-back plate fold 601 arranged on the rear side edge of the side plate 106 and folded inwardly, and a bottom-back plate fold 602 arranged on the rear side edge of the bottom plate 105 and folded upwardly, and the rear side edge of the cover plate 103 has a sixth fold 603 folded downwardly, and the sixth fold 603 is arranged behind the side-back plate fold 601 and the bottom-back plate fold 602.

[0036] The side back plate fold 601 and the bottom back plate fold 602 are formed by folding the side plate 106 and the bottom plate 105 after extension, the integrated design does not need to additionally install the back plate 107, reduces the cost and improves the production efficiency, meanwhile, the cover plate 103 can cover the structure of the back plate 107, improves the appearance of the heat preservation drawer.

[0037] In some embodiments, as shown in Figure 4 The second fixing structure 301 is arranged on the front side of the third fixing structure 401.

[0038] In the embodiment, the second fixing structure 301 and the third fixing structure 401 are horizontally aligned, the second fixing structure 301 is arranged on the front side of the third fixing structure 401, and the length of the inner lining plate 102 from back to front is longer than the length of the cover plate 103, the inner lining plate 102 is firstly connected with the side plate 106 on the front side through the second fixing structure 301, and the cover plate 103 is then connected and fixed with the side plate 106 and the inner lining plate 102 on the rear side of the second fixing structure 301 through the third fixing structure 401, so that the third fixing structure 401 does not need to produce a avoiding structure for avoiding the second fixing structure 301 when the cover plate 103 is installed, the strength of the cover plate 103 is improved, the strength of the inner lining plate 102 is maintained, and the integrity of the product is improved.

[0039] In some embodiments, as shown in Figure 4 The fifth fold 501 is arranged on the lower side of the upper frame of the panel 104 on the front side of the bottom plate 101, and the first panel fold 502 is arranged below the fifth fold 501.

[0040] The fifth fold 501 improves the strength of the inner lining plate 102, and the first panel fold 502 covers the inner lining plate 102, improving the appearance of the outside of the heat preservation drawer.

[0041] In some embodiments, as shown in Figure 4 The second panel fold 503 is arranged on the upper side of the upper frame of the panel 104 on the front side of the bottom plate 101, and the sunken platform 504 is arranged on the front end of the cover plate 103 and matched with the second panel fold 503.

[0042] The second panel fold 503 covers the front side structure of the inner lining plate 102 and the cover plate 103, and the sunken platform 504 matches the second panel fold 503, so that the top surface of the second panel fold 503 and the top surface of the cover plate 103 are parallel after installation, improving the appearance of the outside of the heat preservation drawer. Meanwhile, the second panel fold 503 also limits the upward displacement of the cover plate 103 and the inner lining plate 102, improving the firmness of the structure.

[0043] In some embodiments, as shown in Figures 3-4 The front end of the side plate 106 has an outwardly bent L-shaped folded edge 505, and the left and right sides of the front side of the base plate 101 have third panel folded edges 506, which are folded towards the back side along the left and right sides of the panel, and can be inserted into the L-shaped folded edge 505 and connected by fasteners.

[0044] The L-shaped folded edge 505 is formed by multiple folds of the side plate 106 towards the outside, and does not need to be additionally installed, reducing the wall thickness of the heat preservation drawer, and facilitating the insertion of the third panel folded edge 506 and the connection by screws and other fasteners. In practice, the third panel folded edge 506 is flush with the inside of the side plate 106, ensuring the connection strength and improving the appearance of the inside of the heat preservation drawer.

[0045] The terms and words used in the above description and claims are not limited to the literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present utility model.
