Abstract
The utility model discloses a telescopic vernier caliper, comprising a main ruler and a depth ruler. The depth ruler is hollow and is internally provided with a telescopic ruler. The upper surface of the depth ruler is provided with a semi-circular groove. The telescopic ruler can move inside the depth ruler. Scale marks are arranged at the position where the telescopic ruler is connected with the depth ruler, and the scale marks can be read at the position of the semi-circular groove. During the measurement, the telescopic ruler can be placed inside the depth ruler if the depth ruler is not needed; and when the measurement of depth is needed, the telescopic ruler can be pulled out, the certain scale mark on the telescopic ruler is aligned to the tail end of the depth ruler, and the position of the certain scale mark on the telescopic ruler can be determined through the semi-circular groove at the tail end of the depth ruler. The telescopic vernier caliper is applicable to various occasions in which vernier calipers are utilized.
Description
Technical field
The utility model relates to the field of survey instrument technology, and it relates to a kind of scalable vernier caliper in particular.
Background technology
Present vernier caliper comprises main scale, vernier scale, interior measuring claw, external pelivimetry pawl, pit gauge, and during use, pit gauge often stretches out beyond main scale, when not needing to fathom, not only brings very big inconvenience to measurement, and the pit gauge that the stretches out people of easily stabbing.For this reason, a kind of scalable vernier caliper is proposed.
The utility model content
The utility model is the deficiency for existing product, and provides a kind of simple in structure, is easy to make the scalable vernier caliper that can use in various different occasions.
Scalable vernier caliper of the present utility model comprises main scale and pit gauge, and described pit gauge is hollow shape, inside is provided with shrinkage-rule, and front end is provided with half slot, and described shrinkage-rule can move in pit gauge, shrinkage-rule and pit gauge junction indicate scale, and described half slot place can read scale.
The beneficial effects of the utility model are: (1) if do not need pit gauge, just is placed in shrinkage-rule in pit gauge when using vernier caliper, in the time of need to fathoming, extracts shrinkage-rule, and is convenient handy; (2) simple in structure, be easy to make, only need to change slightly on original vernier caliper, can produce.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial structurtes enlarged drawing of the present utility model.
In figure: main scale 1, pit gauge 2, scale 3, shrinkage-rule 4, half slot 5.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
In the drawings, scalable vernier caliper is comprised of main scale 1, pit gauge 2, scale 3, shrinkage-rule 4 and half slot 5.
Described pit gauge 2 is hollow shape, and inside is provided with shrinkage-rule 4, and front end is provided with half slot 5, and described shrinkage-rule 4 can be in the interior movement of pit gauge 2, and shrinkage-rule 4 indicates scale 3 with pit gauge 2 junctions, and described half slot 5 places can read scale 3.
During measurement, if do not need pit gauge 2, just shrinkage-rule 4 is placed in pit gauge 2; In the time of need to fathoming, extract shrinkage-rule 4, the scale 3 on shrinkage-rule 4 is alignd with pit gauge 2 ends, can judge the position of shrinkage-rule 4 high scales 3 by the half slot 5 of pit gauge 2 ends.
Claims (2)
1. scalable vernier caliper, comprise main scale (1) and pit gauge (2), it is characterized in that, described pit gauge (2) is hollow shape, inside is provided with shrinkage-rule (4), front end is provided with half slot (5), and described shrinkage-rule (4) can move in pit gauge (2), and shrinkage-rule (4) indicates scale (3) with pit gauge (2) junction.
