Fig. 11-14 show schematic diagrams of the flow steps in the installation process. The direction indicated by the arrow in fig. 11 is the installation direction, and for convenience of description, the surfaces on both sides of the limiting hole 5 are sequentially defined as a first surface 501 and a second surface 502 in the installation direction, that is, during installation, the pipe mount 3 first approaches the first surface 501 and then moves in the direction of the second surface 502. The mounting steps will be described in detail below in conjunction with fig. 11-14.

S1: one end of the pipeline installation seat 3 is opposite to the limiting hole 5, the first limiting part 41 of the pipeline installation seat 3 is opposite to the second limiting hole 52, and the pipeline installation seat 3 moves towards the direction close to the limiting hole 5, as shown in fig. 11 and 12;

s3: the pipe mount 3 is rotated relative to the stopper hole 5 (in the rotational direction indicated by the dotted line in fig. 13), so that the second stopper portion 42 is rotated and abuts on the stepped surface 53 of the stopper hole 5, completing the installation, as shown in fig. 14 to 15.

After the mounting is completed, as shown in fig. 14 and 15, the lower surface of the first stopper portion 41 abuts against the second surface 502 of the stopper hole 5, the upper surface of the third stopper portion 43 abuts against the first surface 501 of the stopper hole 5, and the side surface of the second stopper portion 42 abuts against the stepped surface 53, so that the stopper is provided on both sides and one side surface of the stopper hole, and the stopper is provided in the mounting direction, the reverse direction of the mounting direction, and the rotation direction. When the pipeline mounting base 3 needs to be removed, the pipeline mounting base 3 is rotated relative to the limiting hole 5 in the opposite direction of the rotation direction shown in fig. 13, so that the second limiting portion 42 is separated from the step surface, the first limiting portion 41 is continuously rotated to be opposite to the second limiting hole 52, then the pipeline mounting base 3 is moved in the opposite direction of the installation direction, and the pipeline mounting base 3 can be separated from the limiting hole 5, so that the disassembly is completed.

It will be appreciated that inner wall panel 101 has an inner wall panel body and outer wall panel 102 has an outer wall panel body. In some embodiments, the inner wall plate body or the outer wall plate body is provided with a limiting hole 5 having the above structural features, that is, the position of the inner wall plate body or the outer wall plate body where the pipeline 2 is to be installed is provided with the limiting hole 5 in advance, and one end of the pipeline installation seat 3 passes through the limiting hole 5 and is in limiting fit with the limiting hole 5 on the inner wall plate body or the outer wall plate body through the limiting structure 4, so as to achieve installation.

In other embodiments, for example, the shape of the opening pre-opened on the inner wall plate body or the outer wall plate body does not conform to the shape of the limiting hole 5, and the opening cannot be directly used as the limiting hole 5 for installation, in this case, the inner wall plate 101 or the outer wall plate 102 further includes a rotation seat for providing the limiting hole 5.

Referring to fig. 16 and 17, in the present embodiment, the opening 104 of the inner or outer wall plate is shaped as a square hole, which does not have the shape required for the position-restricting hole 5, and thus, a rotary seat 6 for providing the position-restricting hole 5 may be provided. Specifically, an opening 104 is formed in the inner wall plate body or the outer wall plate body, both the first limiting portion 41 and the second limiting portion 42 of the pipeline installation seat 3 can penetrate through the opening 104, the size of the third limiting portion 43 is larger than that of the opening 104, so that the third limiting portion can not penetrate through the opening 104 in the installation direction, and therefore the third limiting portion is limited by one side surface of the inner wall plate body or the outer wall plate body, the inner wall plate 101 or the outer wall plate 102 further comprises a rotating seat 6 which can be separated from the inner wall plate body or the outer wall plate body, the rotating seat 6 and the third limiting portion 43 are respectively located on two sides of the inner wall plate body or the outer wall plate body, a limiting hole 5 provided with the first limiting hole 51 and the second limiting hole 52 is formed in the rotating seat 6, and the surface size of the rotating seat 6 facing the inner wall plate body or the outer wall plate body is larger than that of the inner wall plate body or the outer wall plate body is opened 104. The limiting hole 5 provided by the rotating seat 6 is matched and limited with the limiting structure 4 of the pipeline mounting seat 3, and the matching relation between the limiting hole 5 and the limiting structure 4 is the same as that described above. It is understood that, here, the rotation seat 6 is "detachable" from the inner or outer wall plate body, meaning that: the roating seat 6 can be the state of alternate segregation with interior wallboard plate body or exterior wallboard plate body before the installation, and in the installation, roating seat 6 pastes and leans on in the one side of wallboard plate body or exterior wallboard plate body, and after the installation, roating seat 6 is spacing and install on this side surface of wallboard plate body or exterior wallboard plate body by limit structure 4, provides spacing hole 5 for interior wallboard or exterior wallboard for the scope that pipeline mount pad 3 was suitable for is wider.
