Air blowing type threading device for construction installation

Abstract

The invention discloses an air-blowing threader for building installation, which comprises a threading cylinder and an air source. A winding disk is arranged at the inner lower part of the threading cylinder, and a rotating handle is arranged at the front end of the central axis of the winding disk. A wide wire is wound around, and the other end of the wide wire is connected to the cotton ball. An air gauge is provided on the outer upper part of the threading barrel, a sealing cover is arranged on the outer lower part of the threading barrel, and an air inlet pipe is provided on the upper side of the threading barrel. One end of the air inlet pipe is connected with an air source, the other end of the air inlet pipe extends into the threading barrel and is connected with the ring pipe, and a plurality of air blow pipes are circumferentially installed on the upper side of the ring pipe. The invention has stable structure, high threading efficiency, wide application range, safety and reliability, and is favorable for popularization and application.

Description

technical field [0001] The invention relates to the field of building intelligent installation engineering, in particular to an air-blowing threader for building installation. Background technique [0002] During building installation, the indoor wires are required to be hidden, and the wires need to be routed in wire conduits. Chinese patent (authorized notification number CN 204809763 U) discloses an air-blowing threading device. A plug is provided at the first interface of the three-way pipe. One end of the air pipe passes through the plug and extends into the three-way joint. One end is connected to the air source, and a cotton ball is arranged in the tee joint, the cotton ball is located between the second interface of the tee joint and the nozzle of the air pipe, one end of the wide line is located outside the tee joint, and the other end of the wide line is Introduce it from the third interface of the tee joint and connect it with cotton balls. Although the device h...

AI Technical Summary

Problems solved by technology

Although the device has a simple structure and can be used for threading operations, the wide thread is easy to be knotted when threading, and the gas source is ventilated to the three-way joint, resulting in obvious air leakage, low gas utilization rate, poor threading efficiency, and the three-way joint The adaptability and tightness of the connection between the air outlet end and the line pipe to be threaded are poor, and the adaptability range is small
