Specifically, the waterproof layer is provided in a bag-like structure having an open upper portion, and an upper edge of the waterproof layer extends horizontally outward and is detachably connected to an upper end surface of the cabinet 2 through the horizontal portion. For example, a sub-suction belt 5 may be provided under the horizontally extending portion of the waterproof layer, and a main suction belt 4 may be provided on the upper end surface of the casing 2 to be used in cooperation with the above-described suction belt. More specifically, the sub absorbent tape 5 and the female absorbent tape 4 may be provided as a hook and loop fastener, a zipper, a button, or the like.
With the above technical solution, the present embodiment discloses a foldable thermal insulation box, which includes a box body 2, a box cover 1 and an inner container 3. The inner container 3 comprises a bottom plate 31 corresponding to the bottom wall of the box body 2 and side plates 32 corresponding to the side walls of the box body 2 one by one, the bottom plate 31 and the side plates 32 arranged on the periphery of the bottom plate 31 enclose a chamber for accommodating articles, and the inner container 3 is in a folded state and an unfolded state. When the inner container 3 is in an unfolded state, each side plate 32 is erected around the bottom plate 31 and is spliced with the bottom plate 31, each side plate 32 and the bottom plate 31 support the box body 2, and the box body 2 is unfolded; when the inner container 3 is converted from the unfolded state to the folded state, that is, the side plates 32 are bent downward relative to the bottom plate 31 and stacked on the bottom plate 31, the box body 2 can be folded downward, and the volume of the heat preservation box body 2 can be reduced after the box body 2 is folded. Therefore, the utility model discloses a folding of insulation can has effectively reduced the volume of insulation can.
And because the inner container 3 comprises an outer sleeve layer and a filling layer, the filling layer is contained in the outer sleeve layer. The filling layer can effectively preserve heat, and energy loss caused by convection of air inside and outside the box body 2 is avoided. For example, the temperature outside the cabinet 2 is high, the temperature inside the cabinet 2 is low, and the high-temperature air tends to radiate to the low-temperature air to make the temperature uniform, which causes a problem of poor heat-insulating effect of the thermal insulation cabinet. The collapsible insulation can that this embodiment provided is owing to be provided with the filling layer, and this filling layer can effectively prevent the convection current of the inside and outside air of box 2, avoids cold air to flow out from the box 2 in, therefore can reach better heat preservation effect, and outer jacket layer can protect the filling layer on the one hand, and on the other hand also can radiate back to the heat on outer jacket layer surface in the box 2, therefore, the technical scheme that this embodiment provided also can improve thermal insulation performance.
Example 2
This embodiment is another preferred scheme in parallel with embodiment 1, the technical scheme disclosed in embodiment 1 except for the distinguishing technical features belongs to the scope disclosed in this embodiment, the technical scheme disclosed in embodiment 1 except for the distinguishing technical features is not described repeatedly, and the distinguishing technical features of this embodiment from embodiment 1 are that: the inner container 3 has a different structure, specifically,
the embodiment provides a foldable heat preservation box which comprises a box body 2, a box cover 1 and an inner container 3. The inner container 3 includes a bottom plate 31 and side plates 32, the bottom plate 31 and the side plates 32 disposed around the bottom plate 31 enclose a chamber for accommodating articles, the side plates 32 can be bent downward relative to the bottom plate 31 and stacked on the bottom plate 31, and the box body 2 has a retracted state and an extended state.
The bottom plate 31 and each side plate 32 are separable, and each side plate 32 is clamped between the bottom plate 31 and the inner wall of the box body 2. More specifically, the inner container 3 (excluding the cover plate) includes four side plates 32 and a bottom plate 31, the side plates 32 are clamped in a gap between the bottom plate 31 and the inner wall of the box body 2, the lower parts of the side plates 32 are fastened by the abutting force between the bottom plate 31 and the box body 2, and the upper parts of the side plates 32 are fastened by the mutual matching of the sub-adsorption belts 5 arranged on the upper parts of the side plates 32 and the main adsorption belts 4 arranged on the upper parts of the box body 2.
The clamping scheme between the side plates 32 and the bottom plate 31 is various, and the length of the box body 2 is equal to the sum of the length of the bottom plate 31 and the thickness of the two side plates 32 positioned at the two sides of the bottom plate 31. It should be understood that all equivalent changes and modifications made according to the scope of the present invention are still included in the scope of the present invention.
It should also be noted that: the utility model discloses a so-called "bottom plate" and "curb plate" mean to have certain length, width and thickness, and its length and width are than the shape that thickness is far more big.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
