Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a pipe attached to a terminal opening of a pipe cover used for protecting an air conditioning pipe for transmitting and receiving air between an indoor unit and an outdoor unit of an air conditioner. It relates to a terminal fixing device of a cover.

[0002]

2. Description of the Related Art Conventionally, a terminal fixing device of this kind for a pipe cover has been disclosed in Japanese Utility Model Laid-Open Publication No.
As shown in Japanese Patent No. 31393, a pipe cover end having a cylindrical connecting portion inserted into a terminal opening of a pipe cover and a tapered tube portion is generally used. It has been used by appropriately cutting off the tapered cylindrical portion and fitting the connecting portion into the terminal opening of the pipe cover.

[0003]

However, this type of pipe cover is composed of a two-part tube body consisting of a pipe cover body and a lid for the purpose of improving workability. However, there is a problem that the lid falls down with the passage of time because it is connected only by engagement with the pipe cover body fixed to the pipe cover.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above-mentioned drawbacks of the conventional product, and aims to provide a terminal fixing device for a pipe cover which is easy to construct and does not fall off with a lid over time. It is.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been devised in view of the above, and is provided at a lower end opening of a cylindrical pipe cover composed of a pipe cover body and a lid which can be engaged and connected to each other. A terminal fixture for a pipe cover to be fitted, wherein a presser piece is formed from the pipe cover main body so as to continuously follow the outer peripheral shape of the lid, and the inner peripheral shape of the lid from the pipe cover main body. Forming a receiving piece so as to continuously extend, forming an annular fitting groove provided in the pressing piece and the receiving piece,
A pipe, wherein the inner diameter side gap of the receiving piece is used as an air-conditioning pipe insertion port, and a fixing plate provided for fixing to an outer wall surface is stretched on one side of the holding piece. It is a terminal fixing device of the cover.

In the present invention, the fixing plate is extended laterally or downward at a location located on the wall surface side of the holding piece, and the receiving piece is formed longer than the holding piece. Thereby, the fitting property of the terminal fixture to the pipe cover is improved.

[0007]

According to the present invention, the terminal fixture for a pipe cover has a pressing piece formed so as to continuously follow the outer peripheral shape of the lid from the pipe cover main body, and the inner peripheral shape of the lid from the pipe cover main body. A receiving piece is formed so as to extend continuously, an annular fitting groove formed in the holding piece and the receiving piece is formed, and the inner diameter side gap of the receiving piece is used as an insertion port of an air conditioning pipe. In order to attach the fixing plate to the lower end opening of the pipe cover by fitting the fitting groove portion, in addition, a fixing plate provided for fixing to the outer wall surface is stretched on one side of the pressing piece. The lid of the pipe cover is prevented from falling off.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 and 2 are a perspective view and a longitudinal sectional view, respectively, showing an embodiment of the terminal fixture of the pipe cover of the present invention. The terminal fixing device of the pipe cover according to the present embodiment is formed along the outer peripheral shape of the pipe cover A having a substantially octagonal cross section composed of a pipe cover main body a and a lid b that can be engaged and connected to each other. An annular fitting groove 3 formed by a holding piece 1 and a receiving piece 2 formed longer than the holding piece 1 and formed along the inner peripheral shape of the pipe cover A. The holding plate 2 is formed so that the inner diameter side gap of the receiving piece 2 serves as an insertion port 4 of an air conditioning pipe (not shown), and fixed plates 5 are respectively stretched on both sides of a side of the holding piece 1 located on the outer wall W side. It is.

Since the terminal fixing device of the pipe cover of the present embodiment has the above-described structure, when used, the pipe cover A fixed to the outer wall W by screws to the pipe cover body as shown in FIGS. The receiving piece 2 is fitted into the terminal opening, pressed to fit the fitting groove 3, and the fixing plate 5 is fixed to the outer wall W with screws.

[0010]

As is clear from the above description, the pipe fixing terminal fixing device of the present invention forms a holding piece so as to continuously follow the outer peripheral shape of the lid from the pipe cover body, A receiving piece is formed so as to continuously follow the inner peripheral shape of the lid, an annular fitting groove formed in the pressing piece and the receiving piece is formed, and an inner diameter side gap of the receiving piece is conditioned by an air-conditioning pipe. In addition, a fixing plate for fixing to the outer wall surface is stretched on one side of the holding piece, so that the lower end of the pipe cover can be used without using a caulking agent or an adhesive. The fixing plate is attached by screwing the fixing plate by fitting the fitting groove into the opening, thereby simplifying the construction and preventing the lid from falling off after the construction.
