Abstract
The utility model provides a polyurethane sheet with a novel interface. Arc grooves are respectively arranged in the middle of two ends of the polyurethane sheet, a lap joint groove and a lap joint protruding groove are respectively arranged at two sides of the arc groove at one end of the polyurethane sheet from inside to outside, and a lap joint protruding table and a lap joint concave table which correspond to the lap joint groove and the lap joint protruding groove are respectively arranged at two sides of the arc groove at the other end of the polyurethane sheet from inside to outside. The polyurethane sheet has the advantages of being capable of enabling connection of polyurethane sheets to be tight, good in seal, simple in structure, and capable of meeting the requirement for seal of a refrigerator which needs extremely low temperature.
Description
Technical field
The utility model belongs to the polyurethane sheet field, especially relates to a kind of polyurethane sheet with new interface.
Background technology
Polyurethane sheet is widely used in all kinds of buildings as heat insulating material, especially uses frequent in the freezer industry.In use, the overlap joint problem between polyurethane sheet is paid close attention to by people.Most polyurethane sheet bridging method is to adopt box and pin or eccentric hook and snap close overlap joint and at place, slit filling with sealant in existing technology.But in the low-down situation of temperature of ice house, because fluid sealant and polyurethane are not same substances, there is the difference of shrinkage ratio, causes technical problem poorly sealed between plate to occur, cause heat insulation effect to reduce and energy waste.
Summary of the invention
Problem to be solved in the utility model provides a kind of polyurethane sheet with new interface, and its sealing performance is significantly improved, and especially is fit to the very low freezer of temperature requirement and uses.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: respectively establish an arc groove in the middle part at polyurethane sheet two ends, the arc groove both sides of an end are respectively established an overlap joint groove and an overlap joint tongue from inside to outside therein, and the arc groove both sides of the other end are respectively established an overlap joint boss corresponding with described overlap joint groove and described overlap joint tongue and overlap joint concave station from inside to outside.
Wherein, overlap joint groove corresponding to two ends, overlap joint tongue and overlap joint boss, overlap joint boss can be in square, trapezoidal or the triangle any.
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.

The specific embodiment
As shown in Figure 1, the polyurethane sheet that the utility model adopts, comprise polyurethane sheet 1, respectively establish an arc groove 2 in the middle part at polyurethane sheet 1 two ends, arc groove 2 both sides of an end are respectively established overlap joint groove 3 and one an overlap joint tongue 4 from inside to outside therein, and arc groove 2 both sides of the other end are respectively established from inside to outside an overlap joint boss 5 corresponding with described overlap joint groove 3 and described overlap joint tongue 4 and overlapped concave station 6.
The course of work of this example: during polyurethane sheet 1 overlap joint, overlap joint groove 3 and overlap joint boss 5, overlap tongue 4 and overlap just in time corresponding agreeing with of concave station 6, and column cavity of middle formation is injecting liquid polyurethane in the column cavity, until after overexpansion, cooling, solidifying, the effect of above-mentioned two structures makes the connection of 1 of polyurethane sheet tightr, better tightness, can reach the requirement of the very low refrigerator sealing of temperature requirement, thus energy conservation.
In the above-described embodiments, overlap joint groove 3 corresponding to two ends, overlap joint tongue 4 are square with overlap joint boss 5, overlap joint concave station 6, equally also can replace with in trapezoidal or the triangle any, other shapes that also can other those skilled in the art can expect.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present 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 present utility model.
