Description

Pipeline marking gauge

Belongs to the technical field of:

the invention relates to a pipeline marking gauge of a marking tool for the outer surface of a pipeline, in particular to an angle marking tool capable of conveniently marking a circle around the pipeline according to an axial angle and a longitudinal angle.

Background art:

at present, most of known marking tools can mark straight lines and standard elements on a plane, and when a pipeline needs to be cut off at an oblique angle, the traditional marking tools cannot conveniently mark irregular oval marks around the pipeline according to the required longitudinal angle and axial angle of the pipeline.

The purpose of the invention is as follows:

the invention provides a pipeline marking gauge which can conveniently draw a marking line around the pipeline on the surface of the pipeline according to a required axial angle and a required longitudinal angle.

The invention content is as follows:

the invention is realized by the following steps: the pipeline marking gauge is formed by connecting a slotted shaft bolt, a semicircular angle ruler, a pointer, a handle rod, a handle, a gauge body and an outer U-shaped link, the pivot, interior U type is linked, the angle scale, rotatory pointer is constituteed, the front end of the rule body is linked with semicircle angle scale through fluting type axle bolt, semicircle angle can rotate on open slot axle bolt, install the handle bar on the rule body, install the pointer on the handle bar, the angle scale, rotatory pointer, the handle, the rear end of the rule body has the T-slot, the protruding front end of tail is the T-shape, the rule body links with the tail arch, the tail arch can slide in the T-slot of the rule body, there are protruding pinhole of tail and spout on the tail, it is spacing to have the pivot in the spout, the protruding rear end of tail inserts outer U type chain joint, both ends that outer U type chain joint was last have outer pinhole, the outer pinhole of pivot on inserting outer U type chain joint and the protruding pinhole of tail, it becomes a kind of active link to link outer U type and the protruding fixed of tail. The two ends of the inner U-shaped chain are provided with inner pin holes, the inner U-shaped chain is installed inside the outer U-shaped chain, the inner U-shaped chains and the outer U-shaped chains are fixedly connected into a chain through shaft pins (11), the opening angles of the inner U-shaped chain and the outer U-shaped chain are arc-shaped, when the chain bends, the opening angles of the outer U-shaped chain and the inner U-shaped chain do not confront each other, and the opening angles of the two outer U-shaped chains do not confront each other. During the use, with pipeline marking gauge semicircle angle chi bottom contact pipeline surface, let semicircle angle chi and pipeline axial direction parallel, rotatory pointer is because the action of gravity, automatic vertical ground, according to vertical angle degree requirement, corresponds the scale of angle dish earlier, according to axial degree requirement, the handle is turned round to the axial, corresponds semicircle angle chi scale, with chain around pipeline excircle a week and cell type shaft bolt connection, can follow the chain at this moment and rule, reachs the required vertical angle and the axial angle and rule.

Has the advantages that:

due to the adoption of the scheme, the pipeline marking gauge can conveniently draw the longitudinal angle and the axial angle of the pipeline to cut and mark lines according to different pipeline cutting required angles.

Description of the drawings:

the invention is further illustrated with reference to the following figures and examples.
