Abstract
The utility model provides a polyurethane cold plate suitable for ultralow temperature, belonging to the field of building materials. The polyurethane cold plate has a structure that a wedge-shaped groove is formed at the middle of one end of the polyurethane plate, a small groove is formed at the two sides of the wedge-shaped groove respectively, and small bosses are arranged at the other end of the polyurethane plate and can be correspondingly connected with the small grooves in a plug-in manner. When the polyurethane plate is overlapped, a cavity is formed at the middle of the polyurethane plate, liquid polyurethane is injected into the cavity for solidification, so that the polyurethane cold plate has a better heat insulation effect and is simple in structure.
Description
Technical field
The utility model belongs to building materials field, especially relates to a kind of ultra-low temperature polyurethane freezer plate that is suitable for.
Background technology
Polyurethane is a kind of good heat insulating material, and the sheet material that is used for freezer mostly is polyurethane sheet, and polyurethane sheet generally adopts box and pin or eccentric hook and snap close overlap joint; The back is filling with sealant at the place, slit, and this structure is when the temperature of ice house requirement is very low, because fluid sealant and polyurethane are foreign peoples's material; The shrinkage ratio there are differences; Cause between freezer plate plate poorly sealedly, heat insulation effect reduces, thereby wastes energy.
Summary of the invention
The utility model provides a kind of ultra-low temperature polyurethane freezer plate that is suitable for to the problems referred to above.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: at polyurethane sheet one end, a wedge-shaped impression is established in the centre, and a little groove is respectively established in the wedge-shaped impression both sides, and the other end is provided with the small boss that can correspondingly agree with little groove.
Groove in the middle of said polyurethane sheet one end can be wedge shape, square, arc or trapezoidal in any.
During the polyurethane sheet overlap joint, little groove and small boss agree with, and the middle cavity that forms injects liquid polyurethane in cavity, treat after overexpansion, cooling, to solidify, and make polyurethane sheet with better tightness.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the connection between polyurethane sheet is more tight, and better tightness is simple in structure.
Description of drawings
Fig. 1 is the utility model sketch map.
Among the figure:
1, polyurethane sheet 2, little groove 3, wedge-shaped impression
4, small boss
The specific embodiment
As shown in Figure 1, the utility model is a kind of ultra-low temperature polyurethane freezer plate that is suitable for, and at polyurethane sheet 1 one ends, a wedge-shaped impression 3 is established in the centre, and a little groove 2 is respectively established in the wedge-shaped impression both sides, and the other end is provided with the small boss 4 that can correspondingly agree with little groove 2.
The utility model course of work is: during two polyurethane sheet 1 overlap joints, little groove 2 cooperates grafting with small boss 4, and the middle cavity that forms is injecting liquid polyurethane in the column cavity, treats after overexpansion, cooling, to solidify, and makes polyurethane sheet with better tightness.
Certainly, the groove structure in the middle of the polyurethane sheet two ends can be any feasible shape, like wedge shape, square, arc or trapezoidal.
The effect of above-mentioned polyurethane sheet structure makes the connection between polyurethane sheet tightr, and better heat preservation can reach the requirement of the very low refrigerator insulation of temperature requirement, thus energy conservation.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (2)
1. one kind is suitable for ultra-low temperature polyurethane freezer plate, it is characterized in that: at polyurethane sheet one end, a wedge-shaped impression is established in the centre, and a little groove is respectively established in the wedge-shaped impression both sides, and the other end is provided with the small boss that can correspondingly agree with little groove.
2. the ultra-low temperature polyurethane freezer plate that is suitable for according to claim 1 is characterized in that: the groove in the middle of said polyurethane sheet one end can be wedge shape, square, arc or trapezoidal in any.
