Problems solved by technology

[0002] When the steel pipes are connected, the envelope line formed by the joint between the steel pipes and the steel pipes is called the intersecting line. At present, in the pipeline construction and the production of pipeline connectors, it is generally drawn manually on one of the pipelines. Intersecting lines, or drawn by the template method, this method has the defects of low labor efficiency and large labor load; especially the low accuracy of marking lines, which is easy to affect the quality of products or construction

Abstract

The invention discloses an intersecting line marking tool. A steel tube is locked under a magnetic lock, a fixing support is installed at the upper portion of the magnetic lock, a graduated disc is installed and fixed at the top of the support, the lower end of a dip-angle adjusting rod is movably hinged to the center of the graduated disc through a hinge pin, a supporting arm is arranged on the dip-angle adjusting rod, a guiding groove is formed in an outer circle of the dip-angle adjusting rod in the outer circle bus direction, the guiding pin is installed at one end of the supporting arm, a rotary shaft is installed at the other end of the supporting arm through a bearing, a crank is installed and fixed on the upper end face of the rotary shaft, a diameter adjusting rotary arm is installed and fixed on the lower end face of the rotary shaft and provided with a slotted hole, and a scratch awl barrel is installed in the slotted hole in the diameter adjusting rotary arm through an adjusting nut. The intersecting line marking tool has the advantages of being high in labor efficiency and low in labor intensity and especially has the advantages of being high in line marking accuracy and easily ensuring the product or construction quality.

Description

technical field [0001] The invention relates to a scribing tool, which belongs to the technical field of fitter tools, in particular to a scribing tool for intersecting lines. Background technique [0002] When the steel pipes are connected, the envelope line formed by the joint between the steel pipes and the steel pipes is called the intersecting line. At present, in the pipeline construction and the production of pipeline connectors, it is generally drawn manually on one of the pipelines. Intersecting lines, or drawn by templates, this method has the disadvantages of low labor efficiency and large labor load; especially the low accuracy of marking lines, which is easy to affect the quality of products or construction. Contents of the invention [0003] The object of the present invention is: aiming at the above-mentioned defects existing in drawing related lines in existing pipeline connections, the present invention provides a marking tool, which has wide versatility, ...
