Embedded pipe elbow pipe device

Abstract

The invention relates to a building construction auxiliary tool, in particular to an embedded pipe elbow pipe device. The embedded pipe elbow pipe device comprises a first elbow pipe spring, a second elbow pipe spring, a magnetism-free slide pipe, a magnetic ring and a magnet block, which can penetrate through the inner part of an embedded pipe, wherein the slide pipe sleeves the outer wall of the embedded pipe; the magnetic ring sleeves the outer surface of the slide pipe and is in sliding connection with the slide pipe; the magnet block is arranged between the first elbow pipe spring and the second elbow pipe spring; a flexible rope is arranged between the second elbow pipe spring and the slide pipe; the end part of the second elbow pipe spring is connected with a push-pull rod; and one layer of a deformed rubber block covers the outer part of the magnet block. With the adoption of the embedded pipe elbow pipe device, a traditional manner of estimating by using a mark is avoided so that the position of a turning point is more accurately determined, the embedding quality is improved and convenience is brought to a user.

Description

technical field [0001] The invention relates to a building material installation tool, in particular to a pre-embedded pipe bending device. Background technique [0002] In the process of pipe installation, it is often necessary to bend the pipe at the corner of the building. In the building, the pipe that can be completely used, such as the PVC pipe used in the construction, usually needs to use the bend spring when the PVC pipe is bent. However, after the elbow spring enters the pipeline, it is difficult to effectively grasp the position of the bending point. The method usually used by the construction personnel is to use a thin iron wire to bind one end of the elbow spring, and use the iron wire to make the inflection point of the pre-embedded pipe in advance. Mark well, and then insert the elbow spring into the pre-embedded pipe. When the iron wire reaches the mark, then artificially bend the pre-embedded pipe. Using iron wire marks will often cause the iron wire to bend...

[0002] In the process of pipe installation, it is often necessary to bend the pipe at the corner of the building. In the building, the pipe that can be completely used, such as the PVC pipe used in the construction, usually needs to use the bend spring when the PVC pipe is bent. However, after the elbow spring enters the pipeline, it is difficult to effectively grasp the position of the bending point. The method usually used by the construction personnel is to use a thin iron wire to bind one end of the elbow spring, and use the iron wire to make the inflection point of the pre-embedded pipe in advance. Mark well, and then insert the elbow spring into the pre-embedded pipe. When the iron wire reaches the mark, then artificially bend the pre-embedded pipe. Using iron wire marks will often cause the iron wire to bend during the threading process, resulting in The position of the mark changes, and the elbow spring cannot reach the designated position, causing creases or cracks in the embedded pipe at the inflection point, increasing the difficulty of threading, reducing the quality of the embedded pipe, and causing inconvenience to users
