Wrapping-type iron wire binding tool for sleeve joint of soft pipe and hard pipe and binding method

Abstract

The invention relates to a wrapping-type iron wire binding tool for sleeve joint of a soft pipe and a hard pipe and a binding method. One end of a tool body is provided with an iron wire ejecting pressing groove, and the other end is provided with a winding shaft; the winding shaft is provided with a slit and is connected with a ratchet; the ejecting pressing groove on the tool body tightly presses an iron wire bending place and the free end is clamped in the slit of the winding shaft; through rotating the winding shaft to tighten the free end of the iron wire, tightening on the iron wire wound on a soft pipe is realized; one-way fixing on the winding shaft is realized through match between a telescopic rod of a positioning device on the side wall of the tool body and the ratchet, and thephenomenon that the winding shaft stops tensioning the iron wire to result in looseness can be prevented. The majority of the tensioning force at the free end of the iron wire can be converted to theradial pulling force of the iron wire wound on the soft pipe, the conversion efficiency between the tensioning force at the free end and the radial pulling force of the iron wire wound on the soft pipe is high, the tensioning effects are good, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of iron wire binding, in particular to a wrapped-type iron wire binding tool and binding method for socket connection of soft and hard pipes. Background technique [0002] In daily life, we often need to use iron wire to bind the hose to hard pipes such as steel pipes and plastic pipes to achieve the effect of fastening and connection. Usually, we wrap the wrapped iron wire on the hose and tighten it with hand pliers before winding it. However, most of the force of this tightening method acts on the two free ends of the iron wire when tightening, and the radial tightening force on the iron wire wound on the hose is very small and very It is difficult to tighten the hose and the hard tube. If you want to tighten the iron wire wound on the hose, you need to pull the two free ends of the iron wire hard, so that the iron wire wound on the hose is subject to greater radial tension. Make the contact surface of th...

[0002] In daily life, we often need to use iron wire to bind the hose to hard pipes such as steel pipes and plastic pipes to achieve the effect of fastening and connection. Usually, we wrap the wrapped iron wire on the hose and tighten it with hand pliers before winding it. However, most of the force of this tightening method acts on the two free ends of the iron wire when tightening, and the radial tightening force on the iron wire wound on the hose is very small and very It is difficult to tighten the hose and the hard tube. If you want to tighten the iron wire wound on the hose, you need to pull the two free ends of the iron wire hard, so that the iron wire wound on the hose is subject to greater radial tension. Make the contact surface of the iron wire and the hose fit tightly. At this time, the two free ends of the iron wire have been subjected to a large twisting force. If you continue to tighten it after pulling it, it is easy to twist it off; this binding method requires constant pulling 1. Tighten the free end of the iron wire, and the strength is not easy to control. If the force is too large, the wire will be easily broken. strenuous
