When placing materials inside the sealed box 2, according to the requirements, the angle of the placement plate 18 is adjusted. When it is necessary for the placement plate 18 to tilt downward, the placement plate 18 is rotated downward and its angle is limited by the locking rod 11, which is convenient for observing the samples from the outside. When it is necessary to raise the support cross bar 17 for hanging, in the above-mentioned manner, the placement plate 18 is fixed to tilt upward. At this time, the support cross bar 17 is exposed in the field of vision, and the items that need to be hung and displayed can be hung outside the support cross bar 17.

[0025] Please refer to Figure 1 As shown, two staggered glass doors 3 are slidably connected to one side of the sealed box 2.

[0026] It should be noted that sealing strips are provided on the four sides of the glass door 3 of the present utility model, which can reduce the loss of cold air when opening the door, and the staggered design can achieve the opening and closing of one side, preventing a large amount of hot air from entering the freezer, and at the same time facilitating the efficient display and opening and taking of the display cabinet.
