Abstract
The utility model relates to an amplification type vernier caliper, which consists of a main caliper, a vernier and an amplification lens; the left end of the main ruler is provided with an outer measuring claw and an inner measuring claw, and the ruler body is provided with scale marks; the vernier can slide on the main ruler, the tightness is adjusted by a screw, the left end of the vernier is provided with an outer measuring claw and an inner measuring claw which correspond to the main ruler, and the ruler body is provided with scale marks; the magnifying lens is fixed on the vernier scale body and is tangent to the main scale. The utility model discloses additional magnifying glass piece on the vernier scale body, the scale that can enlarge main scale and the vernier scale body so that the reading makes measuring result more accurate, is applicable to various occasions that need use vernier caliper to carry out accurate measurement.
Description
Technical field
The utility model relates to a kind of survey instrument, especially a kind of amplifying type vernier caliper.
Background technology
Vernier caliper is a kind of measurer of measuring length, interior external diameter, the degree of depth.Vernier caliper by main scale be attached to that slidable vernier two parts constitute on the main scale.Main scale is a unit with the millimeter generally, and 10,20 or 50 lattices are then arranged on the vernier, and according to the difference of lattice, vernier caliper can be divided into ten minutes degree vernier caliper, 20 fens degree vernier calipers, 50 fens degree lattice vernier calipers etc.Two secondary movable measuring jaws are arranged on the main scale of vernier caliper and the vernier, are respectively interior measuring claw and external pelivimetry pawl, and interior measuring claw is commonly used to measure internal diameter, and the external pelivimetry pawl is commonly used to measure length and external diameter.
Though existing vernier caliper can carry out precisely, measurement easily, when reading, be still and adopt the scale mark of visual inspection judgement and main scale and vernier scale thinner, reading is not too convenient and cause measuring error, gives to accurately measure and makes troubles.
The utility model content
Not too conveniently cause the problem of measuring error when having the vernier caliper reading now in order to solve, the utility model provides a kind of amplifying type vernier caliper, and it can amplify main scale, vernier graduation so that reading efficiently solves the problems referred to above.
In order to realize that the technical scheme that the utility model purpose is adopted is: a kind of amplifying type vernier caliper is characterized in that: it is made up of main scale, vernier, enlarging lens; Described main scale left end is external pelivimetry pawl, interior measuring claw, and the chi body is provided with scale mark; Described vernier can slide on main scale, and has screw adjusted elasticity, vernier left end to be provided with and the corresponding external pelivimetry pawl of main scale, interior measuring claw, and the chi body is provided with scale mark; Described enlarging lens is fixed on the vernier scale body, and is tangent with main scale.
The beneficial effect of the utility model is: additional enlarging lens on the vernier scale body, the scale of scalable main scale and vernier scale body are applicable to the various occasions that need the use vernier caliper to accurately measure so that reading makes measurement result more accurate.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the utility model structural representation
1-main scale, 2-vernier, 3-external pelivimetry pawl, the interior measuring claw of 4-, 5-enlarging lens, 6-scale mark among the figure.
Embodiment
In the embodiment shown in fig. 1, a kind of amplifying type vernier caliper is characterized in that: it is made up of main scale, vernier, enlarging lens; Described main scale left end is external pelivimetry pawl, interior measuring claw, and the chi body is provided with scale mark; Described vernier can slide on main scale, and has screw adjusted elasticity, vernier left end to be provided with and the corresponding external pelivimetry pawl of main scale, interior measuring claw, and the chi body is provided with scale mark; Described enlarging lens is fixed on the vernier scale body, and is tangent with main scale.
During use; Transfer unscrew that vernier can be slided along main scale; Select external pelivimetry pawl/interior measuring claw according to the measurement needs, the slip vernier makes measuring claw and measuring object tangent, the relative position of the screw retention of screwing vernier and main scale; Enlarging lens amplifies the scale mark of vernier and main scale chi body, can make things convenient for visual inspection to draw accurate reading.
