The wire harness passes through the wire opening of the wire tube, and the wire opening wraps the wire harness, thereby reducing the gap between the wire harness and the through-hole, reducing the heat dissipation in the room, and having better sealing performance, reducing the probability of external gas entering the room.

[0009] Preferably, there are multiple through-holes, and there are multiple wire-passing tubes, and the wire-passing tubes are arranged in a one-to-one correspondence with the through-holes.

[0011] Preferably, the diameter of the baffle is larger than the diameter of the wall hole, and the baffle is used to cover the wall hole.

[0012] By adopting the above technical solution, the baffles cover the wall holes, blocking the generation of some thermal bridges, reducing indoor heat loss and saving energy.

[0013] Preferably, the diameter of the wire-passing opening decreases as it moves away from the baffle.

[0014] By adopting the above technical solution, it is easy to pass the wire harness through the wire passing port, it is easy to clamp wire harnesses of different diameters, the gap between the wire harness and the wire passing port is reduced, and heat loss is reduced.

[0015] Preferably, the outer diameter of the wire passing tube decreases as it moves away from the baffle.

[0017] Preferably, one side of the heat insulation cloth is provided with an embedding groove, and the embedding groove is used for the baffle to be embedded.

[0018] By adopting the above technical solution, it is easy to assemble the baffle and the insulation cloth, reducing the probability of uneven placement of the insulation cloth and thus affecting the appearance of the wall, and improving the installation efficiency of the wall sleeve.

[0019] Preferably, a bonding portion is provided on a side of the heat insulation cloth facing the wall, and the bonding portion is used for bonding to the wall.

[0020] By adopting the above technical solution, the thermal insulation cloth is bonded to the wall, thereby improving the firmness of the connection between the thermal insulation cloth and the wall and improving the installation efficiency of the thermal insulation cloth.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The thermal conductivity of the fabric is low. The thermal insulation fabric blocks the formation of some thermal bridges, reduces indoor heat loss, saves energy, reduces the probability of wall mildew, and protects people's lives.

[0023] 2. The diameter of the baffle is larger than that of the through-hole, making it difficult for the baffle to fall out of the through-hole. The wire harness passes through the through-hole of the wire tube, and the through-hole wraps the wire harness, reducing the gap between the wire harness and the through-hole, reducing the heat dissipation in the room, and having good sealing performance, reducing the probability of external air entering the room;

[0024] 3. It is convenient to pass the wire harness through the wire port, to clamp wire harnesses of different diameters, to reduce the gap between the wire harness and the wire port, and to reduce heat loss. BRIEF DESCRIPTION OF THE DRAWINGS
