DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting required for attaching a pipe cover for a pipe to a wall of a pipe such as an air-conditioning pipe. An end portion of a tubular pipe cover for arranging the inner space portion in communication with the through hole for use, the end portion of which can be fitted inside, and a sheath attachment portion for attaching the sheath portion to the wall. The present invention relates to a pipe cover mounting tool provided with a mounting body.

[0002]

2. Description of the Related Art In general, the work of attaching a pipe cover, which is the subject of the present technology, is performed after the piping process, so that the pipe cover can be easily installed on the pipe to be covered later. In many cases, the pipe cover is formed so as to be divided in the circumferential direction, and each of the divided members of the pipe cover is engaged with each other along the radial direction of the pipe. Conventionally, as a fitting to attach this type of pipe cover by connecting it to the through hole of the wall,
The end portion of the tubular pipe cover is configured by a mounting body having a sheath portion capable of being fitted inside, and a sheath mounting portion for mounting the sheath portion to the wall. Some were formed in the circumferential direction similarly to the case of the cover.

[0003]

According to the above-mentioned conventional fitting for a pipe cover, since the mounting body is divided in the circumferential direction, it can be easily installed together with the pipe cover even after the piping process. On the other hand, since each of the divided members of the divided mounting tool is assembled by an engaging portion, the engaging portion becomes a weak point portion against intrusion of rainwater or the like, and enters into the pipe cover from the engaging portion. There is a risk that leaked water may leak into the structure through the through hole, and the waterproofness is poor.

In order to improve the waterproofness of such a conventional mounting device, it is conceivable to integrally form the mounting body. In this case, a sheath portion of the integrally formed mounting body and an end portion of the sheath portion are provided. Considering the watertightness of the joint with the pipe cover where the part is inserted, it is necessary to set the dimensions of each other so that there is almost no gap between them, so that watertightness can be ensured. This makes it difficult to insert the end of the pipe cover into the sheath, and thus lowers the efficiency of the work of assembling the pipe cover and its fitting.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pipe cover mounting member which can be easily assembled in view of the above-mentioned drawbacks, and which prevents water entering from the outside when mounted on a wall from leaking into a through hole. To provide.

[0006]

In order to achieve this object, a fitting structure of the pipe cover according to the present invention is characterized in that an inner space is communicated with a through hole for pipe penetration provided in a wall. An end of the tubular pipe cover to be fitted is provided with a sheath portion capable of being fitted inside, and a mounting body having a sheath mounting portion for mounting the sheath portion on the wall is divided and formed in the circumferential direction. An inner cylinder main body is integrally provided with a cylinder portion that can be internally fitted to an end of the pipe cover in an internally fitted state, and a cylinder attachment portion for attaching the cylinder portion to the wall.

It is preferable that the tubular portion is formed so as to be inclined toward the pipe cover when attached to the wall, and furthermore, the tubular portion is radially outwardly extended over the entire circumference at the end of the tubular portion. There may be provided a draining protrusion projecting in the direction.

[0008]

According to the characteristic structure of the fitting of the pipe cover according to the present invention, since the mounting body is formed so as to be divided in the circumferential direction, the pipe is operated by simply engaging the divided members in the radial direction. The mounting body can be easily assembled to the cover, and furthermore, a tube portion that can be fitted inside the end of the pipe cover in a state of being fitted inside the sheath portion, and a tube for attaching the tube portion to the wall. Since the inner cylinder main body integrally formed with the mounting portion is provided, for example, even if water intrudes into the cover from the engaging portion of the mounting main body, the water penetrates by the inner cylinder main body mounted on the wall. Leakage into the hole can be prevented, and the assembling workability and the effect of blocking water leakage can be achieved.

In addition, if the tubular portion is formed so as to be inclined toward the pipe cover when attached to the wall,
The water droplets adhering to the inner cylinder main body are guided to the outer pipe cover side along the slope, so that water leakage into the through-holes can be more easily prevented.

[0010] Further, if a draining protrusion projecting radially outwardly over the entire circumference is provided at the end of the cylindrical portion,
The water adhering to the outer peripheral surface of the cylindrical portion is drained by the projecting portion and flows toward the pipe cover, thereby preventing the water from flowing into the cylindrical portion.

[0011]

Therefore, according to the pipe cover mounting fixture of the present invention, it is possible to easily assemble, while preventing water entering from the outside while mounted on the wall from leaking into the through hole. It is possible to improve the functionality of the pipe cover without lowering the workability of the mounting.
