開口部１６を閉塞キャップ４で塞ぐようにしている。A method of installing the penetrating sleeve 1 'in a wall hole is to insert a decorative plate 3 screwed into the end of one sleeve 2b from one end of the wall into the wall hole, and to insert the other end of the wall. The other decorative plate 3 is screwed into the end of the sleeve 2a from above, and the wall is sandwiched and fixed between the two decorative plates 3, 3 so that a refrigerant pipe of an air conditioner can be inserted into the through sleeve 1 '. It has become. In addition,
When the central opening 16 of the decorative plate 3 is not used, that is, when there is no pipe to be inserted, the central opening 16 is closed with the closing cap 4.

まう恐れがある。However, in the conventional structure in which the decorative plate 3 and the sleeves 2a and 2b are screwed together, it takes time and effort to assemble the penetrating sleeve 1 ', and after installation on the wall. If a counterclockwise force (a force in the direction of loosening the decorative plate 3) is applied with some beat, the connection state between the decorative plate 3 and the sleeve 2a is loosened, and the decorative plate 3 comes off if left as it is. There is fear.

If the sleeves 2a and 2b are arranged with an inclination so that they can be discharged to the outside even if rainwater enters,
The contact portion 6 of the decorative plate 3 and the wall surface 12 may not be parallel, and the contact portion 6 may come into contact with the wall surface 12 to form a gap. Therefore, conventionally, the gap between the screws 40, 41 is increased by making the width b of the valley of the female screw 41 provided on the sleeve 2a larger than the width a of the ridge of the male screw 40 provided on the decorative plate 3 shown in FIG. This makes the decorative plate 3 swingable with respect to the sleeve 2a so as to prevent the contact between the contact portion 6 and the wall surface. In the case where the closing cap 4 is attached to the screw 16 with a screw, when the closing cap 4 is removed and the closing cap 4 is rotated counterclockwise, the gap between the screws 40 and 41 causes There is also a problem that the usability is deteriorated, for example, the screw connection with the sleeve 2a is loosened and the decorative plate 3 is detached together with the closing cap 4.

でき、良好な外観が得られるようになる。Thereafter, the palm is placed on the front of the decorative plate 3 and the decorative plate 3 is rotated clockwise by about 1/4 circumferential axis. (The state shown in FIG. 4B), whereby the sleeve 2a rotates in the same direction and is screwed into the other sleeve 2b, so that the length of the adjustable sleeves 2a and 2b can be shortened. The decorative plate 3 is drawn toward the wall, and both surfaces of the wall can be sandwiched between the decorative plates 3, 3.
Can be abutted. At this time, the sleeves 2a,
When the length of the decorative plate 3 is slightly rotated counterclockwise when the length of 2b is to be increased, the locking projection 9 is
, The length of the sleeves 2a and 2b can be increased while maintaining the fitted state of the decorative plate 3 and the sleeve 2a, and the decorative plate 3 can be prevented from running idle. Further, since the mounting portion 5 of the decorative plate 3 is rotatably fitted around the axis of the sleeve 2a, the decorative plate 3 can be smoothly rotated with respect to the sleeve 2a. The mounting portion 5 of the plate 3 is connected to the sleeve 2a as shown in FIG.
, The decorative plate 3 can be arbitrarily angled within a specific range. That is, as shown in FIG.
Even if the sleeves 2a and 2b are arranged with an inclination so that rainwater flows into the outside and drains down even if it enters, the inclination of the contact portion 6 of the decorative plate 3 with respect to the wall surface 12 can be adjusted freely. 12 can be kept at an angle, so that the decorative plate 3 can be prevented from colliding against the wall surface 12, and a good appearance can be obtained.

ある。After the penetration sleeve 1 is installed, an unexpected rotational force (counterclockwise axial rotational force) may be applied to the decorative plate 3 once installed on the wall surface 12. Release direction (axial direction A of sleeve 2a)
Unless intentional, the likelihood of unexpected force being applied is unlikely. Therefore, in the structure in which the decorative plate 3 and the sleeve 2a are fitted in the axial direction A of the sleeve 2a as in the present application, there is almost no possibility that the decorative plate 3 is unexpectedly disengaged, and a good use state is obtained. Can be maintained.

Since it is formed of R 2 , R 1 ′, and R 2 ′, friction at the contact portion between the inner surface 7 b of the circular tube portion 7 and the locking projection 9 can be eliminated, and the rotation of the decorative plate 3 can be prevented. In addition, the attachment / detachment and the swing with respect to the sleeve 2a become smooth, respectively, and the usability is improved. In addition, since the stopper portion 10 that comes into contact with the locking protrusion 9 of the decorative plate 3 is provided at a position displaced in the circumferential direction B from the notch portion 8 in the circular tube portion 7, the locking protrusion 9 contacts the stopper portion 10. By axially rotating the decorative plate 3 in the direction, the lengths of the length-adjustable sleeves 2a and 2b can be adjusted. That is, since the length of the sleeves 2a and 2b can be adjusted by rotating the decorative plate 3, the usability is improved.

らなくなる。Next, when closing the central opening 16 of the decorative plate 3 with the closing cap 4, as shown in FIG. Then, the closing cap 4 is pushed in the axial direction A, and thereafter, the finger is merely hung on the finger-holding recess 19 of the closing cap 4 and slightly rotated clockwise, as shown in FIG. The collision portion 20 can be locked to the locking portion 24 from the introduction portion 22 through the inclined portion 23. This locking part 24
6A extend in a direction C substantially perpendicular to the axial direction A of the plate body 14 as shown in FIG.
And the locking portion 24 are fitted in the axial direction A of the plate body 14. Therefore, the closing cap 4 can be easily attached without excessively tightening the closing cap 4, so that the closing cap 4 can be securely attached to the plate body 14 without strongly tightening the closing cap 4 as in the related art. Further, since the closing cap 4 is attached to the plate body 14 by the engagement between the engaging projection 20 and the engaging groove 21, unlike the conventional method of mounting the closing cap 4 by press-fitting, the operating environment is different. There is no fear that the closing cap 4 comes off the plate main body 14 due to the influence of the above. Further, in the case of the conventional screw type, since the tightening is performed while rotating with the flat front surface of the closing cap 4, the tightening becomes difficult as it approaches the wall surface 12. However, in the present invention, the closing cap 4 is rotated slightly. Since it is only necessary to push the cover 14 while pushing it, the attachment to the plate body 14 becomes extremely easy, and the mounting and dismounting of the closing cap 4 is not troublesome.

る。Further, by simply rotating the closing cap 4 in one direction, the engaging projection 20 is moved from the introduction part 22 through the inclined part 23 into the locking part 24 in the direction indicated by the arrow in FIG. When the closing cap 4 is rotated in the opposite direction, the engaging projection 20 is smoothly guided in the opposite direction, so that the attaching and detaching of the closing cap 4 is further facilitated. In addition, in the initial stage of fitting of the closing cap 4, the closing cap 4 is in a state of protruding from the front surface of the plate body 14, so that the rotating operation of the closing cap 4 becomes easy, and the engaging projection 20 is moved to the
Is locked in the locking portion 24 extending in the direction C substantially perpendicular to the axial direction A, the front surface of the closing cap 4 is flush with the front surface of the plate body 14, so that the closing cap 4 fits well. And the appearance can be improved. Further, when the closing cap 4 is removed, the front surface of the closing cap 4 projects (floats) from the front surface of the plate body 14, so that the closing cap 4 can be easily removed and the usability is further improved. In addition, since it is only necessary to slightly rotate the closing cap 4 in the reverse direction, it is possible to simultaneously prevent the screw connection between the plate body 14 and the sleeve 2a from loosening and the plate body 14 from coming off.
