Installation and positioning device for drain pipe for building

Abstract

The invention discloses an installation and positioning device for a drain pipe for a building. The installation and positioning device comprises a box; a first telescopic rod is fixedly arranged on one side of the exterior of the box, a second telescopic rod is fixedly arranged at the bottom end of the box, installation blocks are fixedly arranged on the sides, away from the box, of the first telescopic rod and the second telescopic rod, and installation grooves are formed in the sides, away from the box, of the installation blocks; gears are movably installed in the middles of the installation grooves through bearings, the outer sides of the gears are sleeved with limiting rings, first racks are fixedly arranged on the sides, close to the gears, of the limiting rings, and first limitingplates are fixedly arranged on the sides, away from the installation blocks, of the limiting rings; and a second limiting plate and a third limiting plate are movably installed on two sides of the interior of each installation groove, wherein a second rack and a third rack are fixedly arranged on the sides, close to the corresponding gear, of the second limiting plate and the third limiting platerespectively. The installation and positioning device can accurately position the drain pipe and rapidly install the drain pipe according to the angle of a drawing.

Description

technical field [0001] The invention relates to the technical field of building water supply and drainage, in particular to a building drainage pipe installation and positioning device. Background technique [0002] The building water supply and drainage system is a cold water supply system that sends water that meets the water quality standards to the water points of the living, production, and fire-fighting water supply systems. In the installation process of water supply and drainage, the most commonly used is PVC pipes, PVC pipes and It is called hard polyvinyl chloride pipe, which is extruded by hot pressing method after combining polyvinyl chloride resin with stabilizer, lubricant, etc. It is the earliest plastic pipe to be developed and applied. PVC pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of PVC monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceed...
