(Prior Art) Conventionally, for example, a pipe cover as shown in FIG. 5 has been attached to the outdoor outlet of the air conditioning pipe to prevent rainwater from entering. This conventional piping cover 7 has an abutment rib 51,
The base 5 comprises a pedestal 5 having a flange 52, 62 at one end thereof and a main body 6 which are separable with the abutting surface of 61 as a boundary. The flanges 52, 62 are attached to a wall surface (not shown) by a screw 8 to form a base 5. Both of the main bodies 6 were also attached to each other by bolts and nuts (not shown) using the bolt insertion holes 63.

(Problems to be solved by the invention) However, as described above, in the conventional pipe cover, it takes time and labor to mount it on the wall surface at a high place with a screw and to mount the pedestal and the body with a bolt. There is a drawback that the workability is poor, and it was necessary to reduce manual work such as high-rise apartments as much as possible in terms of safety.

Further, in the conventional pipe cover, since screws, bolts, etc. are used, there is a drawback that the screws, etc. may be loosened due to vibrations, etc., and the cover may drop when it is extremely severe.

(Means for Solving Problems) The piping cover of the present invention solves the problems of the conventional product and can be easily attached to the outlet of the air conditioning pipe to the outside, and the back surface and bottom surface are open. The box shape is
It has an outer cover made of an elastic material and an outdoor flanged pipe having a substantially square flange on the outer periphery of one end of the pipe, and is opposed to the back opening side end of both side walls of the outer cover. A pair of claws are projected, and a substantially L-shaped fitting groove is provided on the back surface of the flange of the outdoor flanged pipe, and the claw of the jacket is fitted into the fitting groove on the back surface of the flange of the outdoor flanged pipe. The outer cover is attached to the flange of the outdoor flanged pipe by being engaged with each other.

The jacket may be made of synthetic resin such as ABS resin as in the illustrated example, or may be made of a thin plate of metal such as iron and aluminum. However, when using thin iron plates, it is necessary to take rust prevention measures such as painting.

The outdoor flanged pipe may be made of synthetic resin such as ABS resin as in the illustrated embodiment, or may be made of a thin iron plate by welding or the like.

(Operation) In the present invention, the pipe for air conditioning is inserted into the pipe of the flanged pipe for outdoor use, and the jacket is attached to the flange of the pipe with the outdoor flanged pipe so that the pipe at the outlet port can be opened to the outside. It is covered with an outdoor flanged pipe and a jacket, and the flange of the outdoor flanged pipe shields the outlet port to the outside.

Further, in the present invention, since the outer casing is substantially box-shaped with the back and bottom opened, and is made of an elastic material, a pair of opposed claws of the outer casing are attached to the corners of the flange. By inserting and pressing into the L-shaped fitting groove provided at the corner, both side walls of the outer cover can be elastically deformed. If the outer cover is slid in that state, two sets The claws can be fitted and locked in the L-shaped fitting grooves provided at the four corners.

Further, the flange of the outdoor flanged pipe is formed into a substantially square shape, substantially L-shaped fitting grooves are provided at the four corners on the back surface of the flange, and two pairs of claws facing each other are provided at the end portions on the back surface side of both side walls of the casing. Since it is projected, not only when the piping from the outlet is vertically installed, but also when it is installed horizontally, the outer casing is turned sideways and its claw is approximately L-shaped. The outer jacket can be attached to the flange by fitting and locking in the fitting groove running in the horizontal direction of the mold fitting groove.
