A tool for tightening the joint of a conveying pipeline

Abstract

The invention relates to the field of liquid delivering, in particular to a fastening tool for a conveying pipeline connector. The fastening tool comprises a handle assembly, a transmission assembly and a fastening assembly. The handle assembly comprises a fixed handle, an abutting handle, a driving handle, a handle spring and a limiting rope and is used for providing a handheld end and carriers of the rest of the assemblies. The transmission assembly comprises a rack and a gear and is used for transmitting movement of the handle assembly to the fastening assembly. The fastening assembly comprises a lower sliding block, a lower-position baffle, a lower-position spring, an upper sliding block, an upper-position baffle, an upper-position spring and a tension rope and is used for tensioning an iron wire for fastening the connector. According to the fastening tool, the iron wire for fastening the pipeline connector can be tensioned conveniently and quickly, the mode that the connector is fastened through the iron wire is adopted, thus the economical effect is achieved, and after being fastened, the iron wire is not liable to be loosened, so that the firm effect is achieved. The fastening tool is reasonable in structure, easy to operate, convenient to use and maintain, and suitable for fastening of the pipeline connector.

Description

technical field [0001] The invention relates to the field of liquid transmission, in particular to a fastening tool for the joint of a transmission pipeline. Background technique [0002] Usually, there are two ways to fasten the pipe joints. One is to use tiles and bolts to fasten the connection, and the other is to use iron wires to fasten the connection. It will rust in the environment, and the bolts are easy to slip under high tension, so the first method is not as economical and reliable as the second method, and there is a problem when using iron wire to tighten, that is, it is difficult to operate , when using ordinary pliers to tighten the iron wire, it is very inconvenient to use a lot of force to pull the iron wire, and if the pulling force is not enough, it will easily lead to loosening. Therefore, an easy-to-operate tightening pipe is needed The device of iron wire solves the above problems. Contents of the invention [0003] Aiming at the problems in the pri...
