い欠点があった。[Detailed explanation of the invention] This is a heat insulating layer for relatively small-diameter pipes, such as a heat insulating layer for piping for cooling/heating medium flow that connects the indoor unit and outdoor unit in a separate type cooling/heating machine. Generally, this insulation layer is tightly attached to the outer surface of the pipe, and adhesive tape is wrapped around the outer circumference to protect it from rainwater, etc., but this adhesive tape is resistant to direct sunlight, temperature fluctuations, wind and rain, etc. It is susceptible to aging, breakage, and decreased adhesion due to the effects of heat, and as a result, it has the drawback that it cannot maintain its desired protective function for a long time, such as allowing rainwater to enter the heat insulating layer and reducing its heat insulating performance.

迅速に挿通することができる。The piping 8 etc. is usually relatively long and bent, and when inserting the element E into the heat insulating layer 9 etc. for the piping 8, it is necessary to If the second cylindrical part 3 on the inner fitting side is inserted and moved to the required position while being contracted to the length, the heat insulating layer 9
Even if the pipe 8 is long and bent to correspond to the pipe 8, it can be inserted easily and quickly.
エレメントＥは、これを所要位置まで挿通移動させたの

Coupled with the fact that it is connected in a position above the second cylindrical part 3 on the side, it is possible to ensure that rainwater does not enter into the heat insulating layer 9 even though it is divided into a plurality of elements E. This can be prevented.

ができるに至った。Although various embodiments have been described below, the gist of the present invention is that the piping insulation layer 9 is fitted over the piping insulation layer 9 and the ends of adjacent ones are fitted and connected to each other.
A bellows-shaped main body 1 that is capable of expanding, contracting and bending the elements E constituting a series of protective covers A in the axial direction and self-maintaining each posture, and a connecting cylindrical part integrally connected to both ends of the bellows-shaped main body 1. 2 and 3, a ring-shaped retaining part 4 is formed in one connecting cylinder part 2, and a ring-shaped retaining part 4 is formed in the other connecting cylinder part 3. In the fitted state of both cylindrical parts, a plurality of secured parts 5 that can be elastically engaged with the ring-shaped retaining part protrude from the circumferential surface of the cylindrical part 3 at intervals in the circumferential direction, The piping insulation is characterized in that opposing surfaces of the ring-shaped engaging portion 4 and the secured portion 5 in the direction of element removal are both perpendicular or substantially perpendicular to the cylinder axis. As explained in detail in the examples,
Since both the cylindrical parts 2 and 3 of the adjacent elements }E and E are fitted over a relatively wide area and in close contact, even though the protective force bar A is divided into multiple elements }E... It has become possible to reliably prevent rainwater from entering the heat insulating layer 9, and to maintain the desired heat insulating performance of the heat insulating layer 9 over a long period of time.

。In particular, the bellows-shaped main body 1, which is expandable and bendable and self-maintains each posture, allows for a minimum length even when the heat insulating layer 9 is inserted into the relatively long and curved pipe 8. It can be easily and quickly inserted with one hand in a state where it is kept contracted, and after the external fitting is inserted, the posture can be easily changed and maintained by extending the bellows-like main body 1 according to the bent shape of the piping 8 and the heat insulating layer 9. In addition, among the connecting cylinder parts 2 and 3 at both ends of the element E, one cylinder part 2 has a ring-shaped retaining part 4, and the other cylinder part 3 has a circumferential space on its circumferential surface. A plurality of engaged portions 5 are formed to protrude apart from each other, and the retaining portions 4 and the opposing surfaces of the engaged portions 5 in the element withdrawal direction are both aligned with the cylinder axis. Since the shape is perpendicular or almost perpendicular to the plane, when connecting a plurality of elements with the piping 8 and the heat insulating layer 9 fitted externally as described above, it is difficult to maintain each posture. Although the element can be easily connected without applying extra restoring force, it has a shape in which a plurality of engaged parts 5 protrude in the circumferential direction compared to the cylindrical part 2 which has a ring-shaped engaging part 4. Since the cylindrical portion 3 is more easily deformed, both cylindrical portions 2
, 3 can be fitted together very easily, and the engaging portion 4
The engagement between the engaged portion 5 and the engaged portion 5 can be firmly maintained.
