Abstract

The utility model provides a scribing instrument, which comprises a scribing ruler and a scribing pen. The utility model is characterized in that the scribing ruler comprises a rectangular positioning ruler composed of a level bar and a vertical ruler and a guiding ruler hinged on the rectangular positioning rule, and a scribing through slot is arranged on the guiding ruler. Because the scribing ruler is composed of a positioning ruler with a right angle and the guiding ruler hinged on the positioning ruler and the scribing through slot is arranged on the guiding ruler, various notch lines of different angles can be marked out conveniently, rapidly and directly on the surface of a pipe wall. The utility model has the advantages of flexible operation, high work efficiency and accurate scribing, and thus the scribing instrument is a quite ideal scribing instrument.

Description

A kind of lining instrument

The utility model relates to a kind of lining instrument, and the especially a kind of instrument that can rule at surface of the work comprises marking-out rule and bow pen thereof.

In reality production, life, often to according to actual needs straight tube be made into the bend pipe of various different angles, as union elbow being set at the pipeline turning, perhaps produce circulating line or the like, this union elbow or circulating line are formed by connecting by two joints or more piece bend pipe, for this reason, after pipe need being cut by different angles, weld again.In the prior art, to the cutting of pipe at first is that otch with every pipe joint carries out artificial setting-out, the outer surface that it is centered around pipe after model is carried out is rule, and just can cut the mode of this backwardness afterwards, not only time-consuming taking a lot of work, operating efficiency is low, and accuracy is poor, causes difficulty for the construction of postorder, installation, therefore, be necessary prior art is improved.

The purpose of this utility model is to provide a kind of lining instrument that can mark various angle cut line directly, apace at outer surface of tube wall.

For achieving the above object, the technical solution of the utility model is: it comprises marking-out rule and bow pen, it is characterized in that described marking-out rule comprises the right angle positioning rule that is made of horizon rule and miter square, and be hinged on the right angle positioning rule which is provided with the line groove work rest blade, and work rest blade rotates around pin joint, so that positioning rule is carried out the location of tube wall surface, and work rest blade is realized the line of tube wall surface different angles otch after pin joint turns to required angle.The miter square of described positioning rule is provided with the angle blaze, and horizon rule is used for the location, and miter square is used for the angle of measuring tube wall surface cut line.The top of described work rest blade is hinged on the miter square of positioning rule by screw, so that work rest blade rotates around pin joint, the line groove is located at the work rest blade bottom, so that bow pen marks cut line at tube wall surface when moving along this groove.

The utility model compared with prior art has following advantage and effect: because this marking-out rule is made of the positioning rule at band right angle and the work rest blade which is provided with the line groove that is hinged on the positioning rule, can directly mark the cut line of various different angles easily and quickly at tube wall surface, and flexible operation, high efficiency, therefore line is a kind of comparatively desirable lining instrument accurately.

Fig. 1 is the front view of the utility model;

Fig. 2 is the side view of the utility model.

The specific embodiment that provides below in conjunction with accompanying drawing is described further the utility model, is not limited to this but hold within the utility model.

Among the figure, 1 is positioning rule, and by horizon rule 9 and miter square 10 form right angle chis, 2 for being located at the angle blaze on the miter square 10,3 is work rest blade, and its top is hinged on the miter square 10 by bolt 4 and nut 5, and its underpart is provided with

line groove

6,7 is bow pen, places in the

groove

6, and 8 is workpiece.When needs at workpiece (pipe) when cut line is marked on the surface, the horizon rule 9 of positioning rule is placed workpiece appearance top A point, work rest blade 3 places workpiece appearance middle part B point, again work rest blade 3 is gone to required angle (as 45 °), mark half tube-surface cut line with bow pen 7 along line groove 6, this marking-out rule is placed the another side of workpiece or workpiece is rotated 180 °, simultaneously work rest blade is gone to opposite angle (as-45 °), can mark second half cut line.

Claims

1, a kind of lining instrument comprises marking-out rule and bow pen, it is characterized in that described marking-out rule comprises the right angle positioning rule that is made of horizon rule and miter square, and is hinged on the work rest blade which is provided with the line groove on the right angle positioning rule.

2, marking-out rule according to claim 1 is characterized in that the miter square of described right angle positioning rule is provided with the angle blaze.

3, marking-out rule according to claim 1 is characterized in that the top of described work rest blade is hinged on by screw on the miter square of positioning rule, and the line groove is located at the work rest blade bottom.
