Abstract
The utility model provides a polyurethane plate with a lapping opening. An arc groove is arranged in the middle of one end of the polyurethane plate; two small bosses are respectively arranged on two sides of the arc groove; an arc boss, the radius of which is slightly smaller than that of the arc groove, is arranged in the middle of the other end of the polyurethane plate; two small grooves are respectively arranged on two sides of the arc boss; and the arc boss can be spliced into the arc groove, and the small bosses can be spliced into the small grooves. When the polyurethane plate is lapped, an arc cavity is formed in the middle, and liquid polyurethane is injected for solidification, so that the thermal insulation effect is better, and the polyurethane plate is more applicable to refrigerators at very low temperature.
Description
Technical field
The utility model belongs to building materials field, especially relates to a kind of polyurethane sheet.
Background technology
Most polyurethane sheet bridging method is to adopt box and pin or eccentric hook and snap close overlap joint and the filling with sealant at the place, slit in existing technology.But under the low-down situation of temperature of ice house,, there is the difference of shrinkage ratio, causes to occur between plate poorly sealed, cause the heat insulation effect reduction and the problem that wastes energy because fluid sealant and polyurethane are not same substances.
Summary of the invention
The utility model provides a kind of polyurethane sheet with novel overlap joint mouth to the problems referred to above, especially is fit to the very low freezer of temperature requirement and uses.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: an arc groove is established in the middle part of polyurethane sheet one end; A small boss is respectively established in the arc groove both sides, and polyurethane sheet other end middle part is provided with the slightly little arc boss of the said arc groove radius of radius ratio, and a little groove is respectively established in the arc boss both sides; Described arc groove and arc boss, small boss can cooperate grafting with little groove.
During the polyurethane sheet overlap joint, arcuation cavity of middle formation is injecting liquid polyurethane in the arcuation cavity, treats after overexpansion, cooling, to solidify, and makes firm the snapping into together of polyurethane sheet.
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, can reach the very low advantages such as refrigerator sealing requirements of temperature requirement.
Description of drawings
Fig. 1 is the utility model polyurethane sheet two ends sketch mapes.
Among the figure:
1, polyurethane sheet 2, small boss 3, arc groove
4, little groove 5, arc boss
The specific embodiment
As shown in Figure 1; The utility model is a kind of polyurethane sheet: an arc groove 3 is established in the middle part of polyurethane sheet 1 one ends; A small boss 2 is respectively established in arc groove 3 both sides, and polyurethane sheet 1 other end middle part is provided with the slightly little arc boss 5 of said arc groove 3 radiuses of radius ratio, and a little groove 4 is respectively established in arc boss 5 both sides; Described arc groove 3 and arc boss 5, small boss 2 can cooperate grafting with little groove 4.
The utility model course of work is: during two polyurethane sheet 1 overlap joints; Described arc groove 3 and arc boss 5; Small boss 2 cooperates grafting with little groove 4, and arcuation cavity of middle formation is injecting liquid polyurethane in the arcuation cavity; Treat after overexpansion, cooling, to solidify, make 1 firm the snapping into together of two polyurethane sheets
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.
