Description

Technical Field

[0001] The utility model relates to the technical field of cold storage panels, in particular to a high-performance polyurethane cold storage panel. Background Art

[0002] Polyurethane cold storage board uses lightweight polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that it has very good thermal insulation performance. The exterior of the polyurethane cold storage board is composed of SII, PVC color steel plate and stainless steel plate components. The advantage of this is to prevent the temperature from spreading due to the large temperature difference between the inside and outside of the cold storage board, thereby making the cold storage more energy-saving and improving the working efficiency of the cold storage.

[0003] At present, there are some problems in the use of traditional polyurethane cold storage panels. For example, most of them are not easy to splice, or they do not have high stability after splicing and are prone to loosening. In addition, the functional layer inside cannot be adjusted and replaced according to specific usage conditions, which reduces the practical performance of the cold storage board. For this reason, we propose a high-performance polyurethane cold storage board to solve the problems raised in the above background technology. Utility Model Content

[0007] Furthermore, the board body comprises a metal shell, the interior of which is stacked in sequence with a polyurethane core board, a sound insulation board, a heat insulation board and a flame retardant board, and a metal sealing plate is fixedly connected to the opening of the metal shell by bolts.

[0008] Furthermore, two reinforcing plug plates are fixedly connected to the left side of the splicing strip, and a reinforcing slot adapted to the reinforcing plug plate is provided on the left side of the inner wall of the splicing slot corresponding to the splicing slot of the splicing frame.

[0012] When the utility model splices two cold storage panels, the splicing strip of one of the panels is inserted into the splicing slot of the other panel, and a preliminary plug-in connection is formed by using the vertical rod. At the same time, the reinforcing panel will also slide into the reinforcing slot to improve the tightness and sealing degree of the connection. After the compression screw sleeve is screwed to the threaded portion at the top of the vertical rod, it can be compressed and fixed from the top of the splicing strip.
