Abstract

The utility model provides a multi-purpose rule, comprising a first half body and a second half body that are articulated with each other; the first half body is provided with a first measuring arm and a length scale, and the second half body is provided with a second measuring arm and a scale mark, the scale mark is matched with the length scale and can indicate the distance between a measuring end point of the first measuring arm and a measuring end point of the second measuring arm. When in use, the half bodies can be rotated to complete the measuring work, and can be rotated and folded for storage when not in use, which is extremely convenient to be operated and carried away, and suitable for outdoor measuring work, and can be used as a gauge for the measuring of length or thickness as well as diameter.

Description

A kind of multifunctional ruler

Technical field

The utility model relates to a kind of multifunctional ruler.

Background technology

At present, the diameter measurement of small-sized trees often uses vernier caliper, but the vernier caliper complex structure costs an arm and a leg, and uses and carries also conveniently inadequately, not too is applicable to be similar to tree diameters measurement etc. at the outdoor surveying work that carries out.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple in structure, easy to use and carry, multifunctional ruler that cost is lower.For this reason, the utility model is by the following technical solutions: described multifunctional ruler comprises the first hinged halfbody and second halfbody, on first halfbody, be provided with first gage beam, on second halfbody, be provided with second gage beam, on first halfbody, be provided with the length scale, in the graduated scale that is provided with distance between the measurement terminals that cooperates indication first gage beam and second gage beam with the length scale on second halfbody.

By adopting above technical scheme, the utility model structure is very simple, and cost is low; During use, can finish surveying work by the halfbody that rotates hinge joint, when not using, rotatable back folding is deposited, and is easy to use and be easy to carry, and is suitable for outdoor surveying work, except being used to measure the diameter, also can be used as the survey instrument of length or thickness.

Embodiment

With reference to accompanying drawing.Multifunctional ruler described in the utility model comprises the first hinged halfbody 1 and second halfbody 2, on first halfbody 1, be provided with first gage beam 3, on second halfbody 2, be provided with second gage beam 4, on first halfbody 1, be provided with length scale 5, in the graduated scale 6 that is provided with distance between the measurement terminals that cooperates indication first gage beam 3 and second gage beam 4 with length scale 5 on second halfbody 2.

First gage beam 3 and second gage beam, the 4 curved shapes of cranking arm can avoid measurement terminals 9 and 10 to be subjected to the obstruction of institute's unconventional shape in the object of surveying part when measuring.Drawing reference numeral 13 is the hinge joint screw of the utility model first halfbody 1 and second halfbody 2, and it plays the effect of rotation axis.

Length scale 5 is located at first halfbody 1 on the surface of second halfbody 2, simultaneously, second halfbody 2 also is provided with length scale 7 on the surface of first halfbody 1, in the graduated scale 8 that is provided with distance between the measurement terminals that cooperates indication first gage beam 3 and second gage beam 4 with scale 7 on first halfbody 1, like this, the utility model can positive and negatively use, use convenient, simultaneously, as shown in the figure, first halfbody 1 and second halfbody 2 can also be made symmetry shape, make that manufacturing is also convenient, reduce manufacturing cost.

In the present embodiment, graduated

scale

6 and 8 has been utilized the jag limit of halfbody one end respectively, the hole that graduated

scale

6 and 8 also can adopt in the halfbody to be opened, or adopt other accessory.Graduated

scale

6 and 8 adopts the structure of present embodiments, makes and uses convenient.

As shown in the figure, length scale 5,7 comprises the scale of English unit and the scale of metric unit.The unit length of length scale 5,7 is relevant with the ratio of the radius of gyration of measurement terminals apart from the distance of rotation axis with the scale cooperation place with the ratio and the graduated scale of the standard length of the scale of English unit and metric unit.

When the utility model uses, rotate first halfbody 1 and second halfbody 2, measurement terminals 9 and 10 is on the measurement point of object, at this moment, graduated scale on the halfbody is pointed to the scale on another halfbody, graduated scale scale pointed shows the distance between the object measurement point, such as diameter, thickness, length.

At first halfbody 1 in the face of being provided with projection 11 on the surface of second halfbody 2, second halfbody 2 in the face of on the surface of first halfbody 1 also correspondence be provided with projection 12.Two

projectioies

11 and 12 can be avoided directly contacting with each other friction between scale 5 and the scale 7, make the utility model longer service life.
