Abstract
The invention provides an improved vernier caliper inner diameter measuring auxiliary cover which effectively avoids the disjointing of the connection of the vernier caliper inner diameter measuring auxiliary cover and the vernier caliper and guarantees the using of measuring tools. The improved vernier caliper inner diameter measuring auxiliary cover comprises a depth indicator. The inner diameter measuring auxiliary cover is fixed on the depth indicator, and the inner diameter measuring auxiliary cover comprises a measurement foot fixing end and a measuring end. The improved vernier caliper inner diameter measuring auxiliary cover is characterized in that an installation end is arranged on the depth indicator, a plurality of protrusions are arranged on the installation end, and the measurement foot fixing end is provided with a plurality of grooves fitting in with the protrusions.
Description
Technical field
The present invention relates to the technical field of survey instrument, be specially a kind of improved inner diameter measurement auxiliary sleeve for vernier caliper.
Background technology
The vernier caliper measurement degree of depth is darker using, during the aperture in the same hole that internal diameter does not wait, because the limitation of the measurement pin of vernier caliper, hole internal diameter dark and that do not wait with inner end diameter can't fathom, the applicant has invented a kind of inner diameter measurement auxiliary sleeve for vernier caliper, see Fig. 1, it comprises measurement pin stiff end 1 and the measuring junction 2 of vernier caliper, described measuring junction 2 has a projection 3, inner diameter measurement auxiliary sleeve for vernier caliper is fixed on the vernier caliper, go deep into realizing in the hole that by inner diameter measurement auxiliary sleeve for vernier caliper the degree of depth is darker, the measurement in the aperture in the same hole that internal diameter does not wait, but this vernier caliper inner diameter measurement auxiliary with vernier caliper between adopt screw to be connected, in use, because the inner general more complicated of workpiece for measurement, when the vernier caliper inner diameter measurement is assisted the degree of depth of the circular hole wall in measuring axocoel, unavoidable collision occurs, cause the auxiliary disengagement that is connected with vernier caliper of vernier caliper inner diameter measurement, affected the use of survey instrument.
Summary of the invention
For the problems referred to above, the invention provides a kind of inner diameter measurement auxiliary sleeve for vernier caliper, effectively avoided the connection of inner diameter measurement auxiliary sleeve for vernier caliper vernier caliper to throw off, guaranteed the use of survey instrument.
Its technical scheme is such: a kind of inner diameter measurement auxiliary sleeve for vernier caliper, it comprises pit gauge, the inner diameter measurement auxiliary sleeve is fixed on the described pit gauge, described inner diameter measurement auxiliary sleeve comprises measures pin stiff end and measuring junction, it is characterized in that: be provided with installation end on the described pit gauge, be provided with a plurality of projections in the described installation, be provided with the draw-in groove that a plurality of and described projection cooperates on the described measurement pin stiff end.
In the said structure of the present invention, owing to be provided with installation end on the pit gauge, be provided with a plurality of projections in the described installation, measure on the pin stiff end and be provided with the draw-in groove that a plurality of and described projection cooperates, by the projection on the installation end and the groove fit of measuring on the pin stiff end, realized that pit gauge is connected with the stable of inner diameter measurement auxiliary sleeve, effectively avoided the connection of inner diameter measurement auxiliary sleeve for vernier caliper vernier caliper to throw off, guaranteed the use of survey instrument.
