Abstract

The invention discloses a device for reserving a hole in a wall to facilitate the installation of an air conditioner. The main features are: the central axis of the hole seat of the wall reserved hole device is provided with a reserved hole A for the air-conditioning line pipe to pass through when installing the air conditioner. The right end of the reserved hole A is provided with a right annular groove, and the right There is a right retaining ring in the groove, and a threaded hole is provided at the left end of the reserved hole A, and the threaded hole is connected with the external thread of the cylinder with an integrated structure at the right end of the hole cover. The reserved hole B through which the line pipe passes, the left end of the reserved hole B is provided with a left annular groove, and a left retaining ring is arranged in the left annular groove. The invention can not only meet the construction needs of the reserved holes of the wall with different wall thicknesses under various decoration conditions of the house, but also can double seal the gap between the outer surface of the air-conditioning line pipe and the reserved hole of the wall to prevent rats Mosquitoes, dust, etc. crawl or fly into the house from the gaps in the reserved holes in the wall, reducing the troubles of the residents and improving the physical and mental health of the residents.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a device for reserving holes in a wall for easy installation of an air conditioner. Background technique [0002] Existing houses are all built with a frame structure, and the reserved holes in the walls of the air-conditioning pipes of the existing houses are all formed after pouring the frame structure of the house and building the wall with a section of PVC pipe. Yes, the existing PVC pipe wall reserved hole has a simple structure. When the air-conditioning line pipe passes through the PVC pipe wall reserved hole, there is a gap between the outer surface of the air-conditioning line pipe and the hole wall surface of the PVC pipe wall reserved hole. If there is a large gap, outside mice, geckos, centipedes, cockroaches, and ants will crawl into the house from the gaps in the reserved holes of the PVC pipe wall, and outside mosquitoes, flies, and dust will crawl through the ga...

[0002] Existing houses are all built with a frame structure, and the reserved holes in the walls of the air-conditioning pipes of the existing houses are all formed after pouring the frame structure of the house and building the wall with a section of PVC pipe. Yes, the existing PVC pipe wall reserved hole has a simple structure. When the air-conditioning line pipe passes through the PVC pipe wall reserved hole, there is a gap between the outer surface of the air-conditioning line pipe and the hole wall surface of the PVC pipe wall reserved hole. If there is a large gap, outside mice, geckos, centipedes, cockroaches, and ants will crawl into the house from the gaps in the reserved holes of the PVC pipe wall, and outside mosquitoes, flies, and dust will crawl through the gaps in the reserved holes in the PVC pipe wall. When flying into the house, the outside noise will be transmitted into the house through the gaps in the reserved holes of the PVC pipe wall, which will not only bring troubles to the residents, but also seriously affect the physical and mental health of the residents.
