Conventionally, for example, a condenser pipe in a refrigerator is attached to the inner surface of the outer box, and from that position it is brought out into the machine room through a pipe insertion hole formed in the bottom plate, and the necessary brazing etc. are performed. . A bush made of an elastic material such as rubber or soft vinyl chloride is installed in the pipe insertion hole, and the condenser pipe is inserted through the bush and brought out into the machine chamber.

Figure 5 shows a conventional structure for inserting and extracting a capacitor pipe in this way. In the figure, 1 is the capacitor pipe, 2 is the bottom plate, 3 is the pipe insertion hole formed in the bottom plate 2, and 4 is the pipe insertion hole. This is a bushing installed in hole 3. As shown in FIG. 5, the conventional bushing 4 has an interior with approximately the same diameter (D 4 ) as the condenser pipe 1 on the inlet side.
≒Dp), and is formed in a tapered shape with a smaller diameter (d 4 <Dp) than the condenser pipe 1 on the outlet side, and the condenser pipe 1 is inserted toward it. Then, as shown in FIG. 6, the bush 4 is stretched in the insertion direction of the pipe 1 (downward in the figure) due to friction with the condenser pipe 1, and the contact length with the pipe 1 is changed from l before insertion to l 1 Therefore, there was a problem that the resistance became large and it was difficult to insert the capacitor pipe 1 through it. Further, when a force is applied to the capacitor pipe 1 in the pulling direction from the state shown in FIG. 7 after insertion, for example due to transportation, the bush 4 is compressed and deformed as shown in FIG. As a result, the length of contact with the condenser pipe 1 decreases from l to l2 , and in this case, the condenser pipe 1 is relatively easily displaced in the pulling direction, resulting in the protrusion into the machine room. This has caused problems in that the brazing work and other assembling work become difficult.

In this invention, the inside through which the pipe passes is formed into a tapered shape, with the inlet side being smaller in diameter than the pipe and the outlet side being approximately the same diameter as the pipe, so that the contact length with the pipe can be shortened when the pipe is inserted, and long when the pipe is removed. It is characterized by the following.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. First, in Fig. 1, the same parts as in Fig. 5 are shown with the same symbols, so in the figure 1 is a condenser pipe, 2 is a bottom plate, and 3 is a pipe formed on the bottom plate 2. This is a pipe insertion hole. 5 is a bushing installed in the pipe insertion hole 3. Like the conventional bushing 4, this bushing is made of an elastic material such as rubber or vinyl chloride, but unlike the conventional bushing 4, the condenser pipe 1 The inside to be passed through has a diameter smaller than that of the pipe 1 on the inlet side (D 5
<Dp), the outlet side is approximately the same diameter as the pipe 1 (d 5 ≒Dp)
It is formed in a reverse tapered shape.

Therefore, in the case of the above structure, when the capacitor pipe 1 is advanced toward the inside of the bush 5 and inserted, the bush 5 shrinks and deforms as shown in FIG. 2, and a part of its inner surface separates from the capacitor pipe 1. The contact length with the condenser pipe 1 is
l 3 , which is shorter than the contact length l 2 when the conventional bush 4 is inserted.Moreover, in this case, the contact point is on the outlet side, that is, the contact length is approximately the same diameter as the condenser pipe 1. Because of these, the resistance during insertion is extremely small, and therefore it can be inserted more easily than before. On the other hand, when a force is applied to the capacitor pipe 1 in the pulling direction from the state shown in FIG. 3 after insertion due to transportation or the like, the bush 5 is extended as shown in FIG. 4, and the contact length becomes l4 . As a result, the contact length l 2 is longer than the conventional bush 4 when it is pulled out, and in this case, the bush 5 shortens its elongated partial pressure diameter to increase the frictional force with the capacitor pipe 1, and the capacitor Since even the outlet side portion, which has approximately the same diameter as the pipe 1, acts in this way, the resistance when the capacitor pipe 1 is pulled out becomes extremely large, and therefore the capacitor pipe 1 is not oriented in the direction of pulling it out. Therefore, sufficient protruding dimensions within the machine room can be ensured, and necessary brazing and other assembling operations can be performed quite easily.
