As shown in Figures 1 to 5, the present invention is free to change the angle of the outer surface of the double tube 200 or the cut surface of the tube 200 or the outer body 200 and the heating tube 210 is sheathed The sealing cover assembly 100 which can be used for sealing the opening surface of the heat insulating material 400 or the gap (G) of the straight and curved structure.

The sealing cover assembly 100 is largely composed of two parts, which cover the plurality of cover members 110 and the respective cover members 110 to interconnect and cover each of the cover members 110 for easy angle change. It consists of a hinge shaft 140 for speech.

Here, the cover member 110 is made of a non-ferrous metal material, one side is narrow and the other side of the shield portion 120 having a relatively wide shape, and extending to one side and the other side of the shield portion 120 is bent It is composed of a coupling piece 130.

At this time, each cover member 110 may be configured to be easily coupled to each other (假) through the connection band 122 is connected to the side of the shielding portion 120 to facilitate storage and assembly. The connection band 122 may be configured by forming a cutout groove 123 at the connection portion with the shield 120 so that the cover member 110 can be easily separated by applying a slight manipulation before and after the cover member 110. Shown in Fig. 3A)

The shielding part 120 is a part in close contact with an open surface and has a structure having a trapezoidal shape as a whole. The shape of the shielding unit 120 is not limited thereto, and a rectangular shape having the same width on one side and the other side may be possible, but a trapezoidal shape is preferable in terms of saving material.

The trapezoidal configuration of such a shielding portion 120 is the overlap of the adjacent cover member 110, after changing the angle of the inner curvature is smaller than the curvature of the outer bar, in consideration of this to narrow the width of one side material of unnecessary parts It is to help reduce.

On the contrary, the outer portion has a larger rotational curvature than the inner side, so that the overlapped portions do not deviate from each other when the angle is changed. As a result, the gap is not generated on the other side where the rotational curvature of the shield 120 is large. This is to avoid exposing the contents stored in the insulation (insulation material) or to make a complete seal.

In addition, the coupling piece 130 is a structure that is bent by extending to one side and the other side of the shield 120.

It can be configured by forming only the unevenness 141 or the through hole 142 on both sides. The concave-convex 141 and the through-hole 142 have the advantage of simplifying the structure and also easy coupling because it does not need to use a separate coupling means such as rivets and hinge pins.

On the other hand, one side width direction of the shield 120 of the cover member 110 may further include two stopper protrusions 121 for limiting the angle of the overlapped cover member 110.

The stopper protrusion 121 functions to prevent the overlapping shielding portions 120 from deviating from each other when the angle of each cover member 110 is changed around the hinge shaft 140. That is, the other side having a large rotational curvature of the shielding part 120 does not expose the overlapping portion so as not to expose the contents, such as the heat insulating material stored in the adherend, or to achieve a complete sealing.

Meanwhile, at least one groove 150 is further formed on one surface or the other surface of each cover member 110 to facilitate bending of the coupling piece 130 to the interface between the shielding part 120 and the coupling piece 130. It is a structure to be formed.

The groove 150 is formed at a predetermined interval in the direction of the coupling piece 130 on the basis of the groove 150 formed on the interface between the shielding portion 120 and the coupling piece 130.

This structure functions to bend the coupling piece 130 of the cover member 110 overlapped with each other more easily, and optionally, if the length of the shielding portion 120 is shorter than the adhered surface, a plurality of grooves 150 formed In order to adhere to the adherend to the coupling piece 130 through).
