Abstract
The utility model discloses a box with thermal insulation, comprising a box body and a box cover, be equipped with the heavy groove of annular on the oral area tank wall of box top, be equipped with on the case lid bottom surface with the first annular that the groove corresponds, the prolonged downward of sinking is protruding. Be equipped with the second annular arch or the boss of prolonged downward on the case lid bottom surface, the outer wall of second annular arch or boss pastes tightly the internal face of box, heavy trench in the roughly middle part of box tank wall thickness of annular. The utility model discloses owing to be equipped with annular heavy groove on the box pushes up the oral area tank wall, it is protruding to be equipped with first annular that correspond with heavy groove, the prolonged downward on the case lid bottom surface, when the case lid lock is on the box, owing to annular heavy groove and the bellied mutual interlock effect of first annular, has increased its sealing performance, and the gas tightness is good, has improved the thermal insulation performance of box to the case lid is difficult for droing during the use. And be equipped with the second annular arch or the boss of prolonged downward on the case lid bottom surface, and form the multiple layer sealing structure, further improved the thermal insulation performance of box.
Description
Technical field
The utility model relates to a kind of insulation can, especially a kind of insulation can of good heat insulating.
Background technology
The insulation can that existing foamed materials is made, be made up of casing and case lid, the buckling parts of casing and case lid is generally adopt inside and outside flanged structure, namely along the bulge loop stretched on cabinet wall is provided with, be provided with down along case lid bottom surface outer rim the bulge loop stretched, the thickness of two bulge loops is generally the half of tank wall thickness, and the fastening structure design of this insulation can is unreasonable, case lid is easily caused to be opened, poor air-tightness, can distribute larger heat, causes heat insulation effect poor.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of insulation can of good heat insulating.
For solving the problems of the technologies described above, the utility model comprises casing and case lid, its constructional feature is that described casing top oral area tank wall is provided with annular deep gouge, described case lid bottom surface be provided with corresponding with described deep gouge, under the first annular protrusion of stretching, described case lid bottom surface is also provided with down the second annular protrusion stretched, described second annular protrusion is positioned at described first annular protrusion circle, and the outside wall surface of described second annular protrusion is adjacent to the internal face of described casing.
Described annular deep gouge is positioned at the roughly middle part of casing tank wall thickness.
The described annular deep gouge degree of depth is slightly larger than the length of stretching under the first annular protrusion; Described annular deep gouge width and the first annular projection thickness basically identical.
Described first annular protrusion is roughly concordant with the second annular protrusion bottom surface.
Described casing and case lid are made up of foamed materials.
After adopting said structure, owing to being provided with annular deep gouge on the oral area tank wall of casing top, case lid bottom surface be provided with corresponding with deep gouge, under the first annular protrusion of stretching, when case lid is fastened on casing, due to the mutual interlocking of annular deep gouge and the first annular protrusion, add its sealing property, air-tightness is good, improve the heat-insulating property of casing, and case lid difficult drop-off when using.And the second annular protrusion stretched under being provided with on case lid bottom surface or boss, the outside wall surface of the second annular protrusion or boss is adjacent to the internal face of casing, forms multi-layer sealing structure, further increases the heat-insulating property of casing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the Split type structure schematic diagram of Fig. 1;
Fig. 3 is the structural representation of the another kind of embodiment of the utility model;
Fig. 4 is the Split type structure schematic diagram of Fig. 3.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, this insulation can comprises the casing 1 and case lid 3 be made up of foamed materials, and the thickness of casing 1 wall thickness and case lid 3 is generally 4-6cm.Push up on oral area tank wall at casing 1 and be provided with annular deep gouge 2, annular deep gouge 2 is positioned at the roughly middle part of casing 1 tank wall thickness, case lid 3 bottom surface is provided with corresponding with deep gouge 2, under the first annular protrusion 4 of stretching, the length that annular deep gouge 2 degree of depth is stretched for 4 times slightly larger than the first annular protrusion, annular deep gouge 2 width and the first annular protrusion 4 thickness basically identical.In order to increase sealing property, the second annular protrusion 5 stretched under case lid 3 bottom surface is provided with, this second annular protrusion 5 is positioned at the circle that the first annular protrusion 4 is formed, the outside wall surface of the second annular protrusion 5 is adjacent on the internal face of casing 1, during making, first annular protrusion 4 is roughly concordant with the second annular protrusion 5 bottom surface, and namely the first annular protrusion 4 is consistent with the second annular protrusion 5 length, the first annular protrusion 4 and the second annular protrusion 5 thickness also basically identical.
Insulation can shown in Fig. 3, Fig. 4, substantially identical with aforementioned structure, its first annular protrusion 4 stretched under having i.e., difference is: the boss 6 stretched under being provided with on case lid 3 bottom surface, boss 6 is positioned at the circle that the first annular protrusion 4 is formed, annular upper groove 7 is formed between the peripheral outer wall face of boss 6 and the first annular protrusion 4 peripheral inner wall face, the peripheral outer wall face of boss 6 is adjacent on the internal face of casing 1, first annular protrusion 4 is roughly concordant with boss 6 bottom surface, and annular upper groove 7 degree of depth is slightly larger than annular deep gouge 2 degree of depth.
The utility model owing to being provided with annular deep gouge on the oral area tank wall of casing top, case lid bottom surface be provided with corresponding with deep gouge, under the first annular protrusion of stretching, when case lid is fastened on casing, due to the mutual interlocking of annular deep gouge and the first annular protrusion, add its sealing property, air-tightness is good, improves the heat-insulating property of casing, and case lid difficult drop-off when using.And the second annular protrusion stretched under being provided with on case lid bottom surface or boss, the outside wall surface of the second annular protrusion or boss is adjacent to the internal face of casing, further increases the heat-insulating property of casing.
