Abstract

The utility model relates to a pair of multifunctional combined divider calipers for pipelines, comprising a pair of calipers, a centering hammer and a scratch awl. The utility model utilizes the characteristic that the scratch awl can move up and down along the hole of the calipers to solve the difficult problem that the engaging track of pipelines is difficult to draw when inserting. The utility model has the advantages of artful structure, convenient application and easy control and popularization.

Description

Multifunctional combined divider calipers for pipeline

The utility model relates to a kind of divider calipers for building, and the line tool in installing especially for pipeline belongs to drawing Work tool technical field.

In building, installation or mechanical manufacturing field, when two pipe fitting quadratures or oblique are welded together, need at first draw crosslinked outline line in the welding position, then according to line cutting welding, this stitching is drawn unusual trouble, tables look-up and calculates and often exhaust a lot of energy.Carelessness is arranged slightly, promptly cause fit clearance excessive, influence welding quality.And the setting-out technology also non-general workman can grasp.

The purpose of this utility model be the development a kind of special use divider calipers, it can treat the crosslinked stitching that draws on the weldment at an easy rate, and have easy to use, the characteristics that are easy to grasp.

The purpose of this utility model is by a scale of being convenient to regulate being set and drawing pin and realize, below with reference to accompanying drawing the utility model being done further narration.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the profile of centering hammer;

The utility model by scale 6, draw pin 5 and 7 of centering hammers form, wherein, scale is a straight chi shape structure, on a hollow slideway is arranged, the centering hammer namely is fixed in the slideway, is provided with a hole at an end of scale, draws pin and namely inserts in this hole. Centering hammer is made up of centering body and fixed bar, the former have one top, in order to determine the center of divider calipers, there is spiral shell on latter surface Line can screw in the centering body, also be provided with on the fixed bar tight female 3 so that the hammer of will feeling relieved is fixed on the arbitrary desired location on the slideway. The top design of fixed bar 2 becomes oblong handle 1, uses holds when being convenient to adjust.

Draw to cooperate between the hole on pin and the centering hammer and want proper, make its up and down slippage, can guarantee littler gap error again.

On centering hammer 7, also be provided with a through hole 8, but draw in pin 5 patchholes.Its effect is in divider calipers time spent not, is convenient to the picture pin taken off put into it, so that dwindle placement space as far as possible.

This divider calipers also can make horizon rule or the right angle guiding ruler uses, so be provided with level 4,9 on scale, configuration is orthogonal between them.

Bar heart place at the fixed bar 2 of centering hammer is provided with a through hole 10, and its aperture can be selected in the 2-3 millimeter, and its effect is after fine rule is penetrated through hole, the centering hammer can be made plummet and use.

On the shaft of drawing pin 5, be provided with rule, on the centering body of centering hammer, also be provided with scale, and the end at scale is provided with top 11, like this, after inserting the picture pin in the through hole of hammering into shape of feeling relieved, also can make compasses and use, a side of scale can be made into dovetail shaped, so that when on the surface of irregularity, using, can place reposefully on its surface.

When the utility model was made the pipeline divider calipers and used, at first will feel relieved to hammer into shape fixed, and mixes up the divider calipers rule, is the center of circle to be fixed a point by the intubate road, and the performance of utilizing the picture pin to move up and down can be along the draw projecting figure of grafting pipeline of pipeline.According to same principle, also can draw by the kiss map interlinking shape in intubate road in the end of grafting pipeline.To grafting at an angle, also can handle like this.

This is novel also to can be used as another kind of compasses and uses, and needs this moment pictures pin is taken off from scale, injects in the hole of centering hammer, and locking top 11 to be the centering pin of compasses, is regulated the angle of centering hammer, can do the compasses use.

Utilize scale, centering hammer dexterously and draw pin, and be located at two levels on the scale, can become square chi, guiding ruler or a T-square.In a word, multiple functions such as the utility model collection divider calipers, ruler, horizon rule, angle square, guiding ruler, plummet are one, have particularly solved the difficult problem that the track of grafting body is difficult to draw in the pipeline operations, has bigger practical value, and it is simple in structure, and it is convenient to use, and is easy to make and promote.
