The convex stupefied cross section is isosceles trapezoid, and the lesser face in the convex stupefied face being parallel to each other is fixed on On the side of cold storage plate;
The cross section of the caulking groove is isosceles trapezoid, described convex stupefied to be inserted into the caulking groove in a top down manner.
Wherein, the convex stupefied and caulking groove quantity is 2-4, and uniform intervals are arranged.
In the preferred embodiment in the utility model, it is described it is convex it is stupefied between caulking groove also pass through polyurethane adhesive be bonded.
In the preferred embodiment in the utility model, the convex stupefied abutting edge between caulking groove is also covered with sealing plate.
In the preferred embodiment in the utility model, securing plate is additionally provided on the outside of the cold storage plate.
Compared with prior art, the utility model has the beneficial effects that
Interior core material of the polyurethane heat-insulation cold storage plate of the utility model using polyurethane as cold storage plate, polyurethane it is heat-insulated Performance is very good, the outside of polyurethane cold-storage board combined by PVC color steel plate, insulating layer, thermal insulation layer and stainless steel plate layer and At preventing cold storage plate because the larger propagation for leading to temperature of internal-external temperature difference to keep freezer more energy saving improves the work of freezer Make efficiency.It is closely coupled by the convex stupefied embedded structure grafting with caulking groove between the cold storage plate of the utility model, it solves existing There is the problems such as poor air-tightness of the plate seam crossing of freezer and refrigerating chamber, heat insulation effect is undesirable, has than common cold storage plate Better air-tightness can prevent cooling gas leakage, be effectively guaranteed the heat insulation effect of freezer, refrigerating chamber, and setting adds on the outside Solid plate prevents tilting, prolongs the service life.In addition, the utility model is resisted using two sides setting steel plate layer and embedded structure Pressure property is strong, fold resistance is excellent, stability is good, smart structural design, novel, and performance is stablized, and long service life is easy to extensive It promotes and applies.
Detailed description of the invention
It, below will be to institute in embodiment or description of the prior art in order to illustrate more clearly of the technical solution of the utility model Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some of the utility model Embodiment for those of ordinary skill in the art without creative efforts, can also be attached according to these Figure obtains other attached drawings.
Fig. 1 is the structural schematic diagram of polyurethane heat-insulation cold storage plate provided by the embodiment of the utility model.
Fig. 2 is the cross-sectional view of polyurethane heat-insulation cold storage plate provided by the embodiment of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are in the premise for not making creative work Under every other embodiment obtained, fall within the protection scope of the utility model.
