Abstract
The utility model discloses a novel vernier caliper. A second measuring jaw on the vernier caliper can be disassembled; when the size of an object to be measured exceeds a certain scope out of a measuring range, and the second measuring jaw is disassembled and assembled in a fixed position at the tail end of a depth ruler. Since the extending length of the depth ruler is consistent with the reading on the vernier caliper and the total length A of a main ruler calculated from the zero point is indicated, the sum of the reading on the vernier caliper and the total length A of the main ruler is the actual size of the object to be measured.
Description
Affiliated technical field
The utility model relates to a kind of novel vernier caliper, particularly can increase the vernier caliper of range.
Background technology
Vernier caliper is a kind of survey instrument that people use always, by main scale and be attached on the main scale slidable vernier scale and form, two secondary movable measuring jaws is arranged, measuring claw and outside measuring jaw in being respectively on main scale and the vernier scale.Vernier caliper can not only Measuring Object interior external diameter and length, the also energy measurement degree of depth simultaneously.But, when reality is used vernier caliper, running into the not enough situation of range through regular meeting, areal survey can bring bigger error again, has brought significant limitation to use.
Summary of the invention
In order to reduce vernier caliper limitation in use, increase its measurement range, the utility model provides a kind of novel vernier caliper, and it can to a certain degree increase the range of vernier caliper under the prerequisite that does not increase attachment device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel vernier caliper, form by main scale and attached to it the vernier scale that can slide, it is characterized in that: second measuring jaw on the vernier scale is demountable, and it can be combined to the fixed position of pit gauge end.Second measuring jaw on the vernier scale is demountable, and it can separate with vernier scale, can combine by bolted mode with vernier scale again.The end of pit gauge has two bolts hole, and there are two bolts at the back side of second measuring jaw, and second measuring jaw that disassembles can be combined to the end of pit gauge by bolted mode.Because pit gauge and vernier scale are one, so second measuring jaw just can be with the same moved further of vernier scale.When testee size no to scale certain limit, second measuring jaw is combined to the end of pit gauge, object is put between two outside measuring jaws or the measuring claw, read the reading on the vernier scale, because the pit gauge extension elongation is consistent with the vernier scale reading, and the total length A of main scale indicates, is the physical size of the object of surveying this moment so the reading of vernier scale adds the total length A of main scale.
The invention has the beneficial effects as follows: can under the prerequisite that does not increase other attachment devices, to a certain degree increase the range of vernier caliper, simple in structure, convenient and practical.

1. main scales, 2. vernier scales, 3. pit gauges, 4. vernier scale left end bolts, 5. pit gauge terminal stud holes, 6. fastening bolts, 7. second measuring jaw bolts hole, 8. second measuring jaws among the figure
Embodiment
In Fig. 1, set up three bolts (4) at vernier scale (2) left end, set up two bolts hole (5) at pit gauge (3) end, on main scale (1) end, indicate main scale total length A.
In Fig. 2, set up two fastening bolts (6) at the back side of second measuring jaw (8)
In Fig. 3, the position of three bolts hole (7) on second measuring jaw (8) right side is corresponding mutually with the position of vernier scale (2) left end bolt (4).
In the embodiment shown in fig. 4, two fastening bolts (6) by second measuring jaw (8) back side are combined to the end of pit gauge (3) with it, the position in pit gauge terminal stud hole is gone up zero distance X according to second measuring jaw (8) and main scale (1) and is set, and has so just guaranteed the authenticity of measuring.As figure, the object physical size of surveying is that the reading of vernier caliper adds the main scale total length A that calculates from zero point.
Claims (1)
1. a novel vernier caliper is made up of main scale and attached to it the vernier scale that can slide, and it is characterized in that: second measuring jaw on the vernier scale is demountable, and it can be combined to the fixed position of pit gauge end.
