Embodiment 1
[0037] Embodiment one; Combine figure 1 with figure 2, is a prefabricated outer heat preservation box disclosed by the present invention, comprising a frame 1 and an outer heat preservation layer 4 wrapped on the outside of the frame 1 . The frame 1 comprises two end brackets 11 arranged parallel to each other, a back vertical bar 12 arranged between the two end brackets 11 and a front vertical bar 13 arranged between the two end brackets 11 .
[0038] Two back vertical bars 12 are provided between the end brackets 11, at least one front vertical bar 13 is provided, and two back and front vertical bars 13 are arranged parallel to each other. When one front vertical bar 13 is provided, the frame 1 is in the shape of a triangular prism as a whole. When two or more front vertical bars 13 are provided, the cross-section of the frame 1 is a quadrilateral or a polygon with more than four sides.
[0039] This embodiment is described by setting two front vertical bars 13, and the f...
Embodiment 2
[0049] Embodiment two; With reference to Figure 4 , is a prefabricated external insulated box disclosed by the present invention, the only difference from the embodiment is that the connection between the front panel 424 and the frame 1 is different. The front plate 424 is rotatably connected to the right side plate 423 . And the sealing ring 9 is interposed between the side wall of the front plate 424 and the rod 111 and the front vertical bar 13 .
[0050] A locking mechanism 8 for locking the relative positions of the front plate 424 and the left side plate 422 is provided between the front plate 424 and the left side plate 422 . The locking mechanism 8 includes a limit pin 81 , a spring 82 and a fixing plate 83 . The limiting pin 81 vertically passes through the left side plate 422 and is slidably connected to the left side plate 422 , and the fixing plate 83 is fixed on the side of the limiting pin 81 away from the right side plate 423 . One end of the spring 82 is fi...
