Abstract
The utility model relates to a novel vernier caliper which comprises a main vernier caliper, a vernier and a depth gauge, wherein the main vernier caliper and the vernier are respectively provided with an outer measuring jaw and an inner measuring jaw which correspond to each other mutually, besides, the main vernier caliper and the vernier are provided with master graduations and vernier graduations respectively; the depth gauge and the vernier are fixedly connected; and a convex lens for amplifying is covered on the vernier graduations of the vernier. Compared with an ordinary vernier caliper, the novel vernier calipe can identify the graduation at the highest aligning degree between the main vernier caliper and the vernier more accurately, therefore, measurement precision is improved.
Description
Technical field
The utility model relates to the hardware ﹠ tools field, specifically is a kind of scale value can the amplification, thereby makes the more accurate vernier caliper of measurement.
Background technology
Present vernier caliper is mainly by main scale, vernier scale, pit gauge constitutes, wherein all be carved with scale on main scale and the vernier scale, by moving of vernier scale, testee is sandwiched between main scale and the vernier scale, then can directly read the integer portion (is unit with the millimeter) of testee size from the scale of main scale, check the scale that vernier scale and main scale align again, thereby calculate the fractional part of testee size, yet, because there are several adjacent scales in vernier scale scale and main scale scale, all seem alignment, it is the highest therefore to be difficult to determine which bar scale degree of registration of the end with naked eyes, therefore, its measuring accuracy also is short of to some extent.
Summary of the invention
At above-mentioned problem, the purpose of this utility model is to provide a kind of novel vernier caliper, and this novel vernier caliper is compared with common calliper, can differentiate vernier scale and the highest scale of main scale degree of registration more accurately, thereby improves the degree of accuracy of measuring.
The technical scheme that its technical matters that solves the utility model adopts is: this novel vernier caliper comprises main scale, vernier scale, pit gauge, described main scale and vernier scale are provided with the outer measuring jaw and the interior measuring jaw of mutual correspondence, and be carved with master calibration and vernier graduation on described main scale and the vernier scale respectively, described pit gauge and described vernier scale are fixed, and described vernier scale is coated with convex lens that are used for amplification above described vernier graduation.
As preferably, described convex lens are rectangular, are installed on the described vernier scale by the draw-in groove of being located at described vernier scale top.
As preferably, the enlargement factor of described convex lens is more than 2 times.
The beneficial effects of the utility model are: this novel vernier caliper in use, because the amplification of convex lens, make main scale contact with vernier scale the part master calibration and vernier graduation be exaggerated, thereby make the operator can clearly tell vernier scale and the highest scale of main scale degree of registration, thereby improve the degree of accuracy of measuring.
Description of drawings
Fig. 1 is the front elevation of this novel vernier caliper.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
Below in conjunction with drawings and Examples this novel vernier caliper is further specified:
Among the embodiment as shown in Figure 1 and Figure 2, this novel vernier caliper comprises main scale 1, vernier scale 2, pit gauge 3, described main scale 1 and vernier scale 2 are provided with the outer measuring jaw 122 and the interior measuring jaw 121 of mutual correspondence, and be carved with master calibration and vernier graduation respectively on described main scale 1 and the vernier scale 2, described pit gauge 3 and described vernier scale 2 are fixed, and described vernier scale 2 is coated with convex lens 21 that are used for amplification above described vernier graduation.
Above-mentioned novel vernier caliper, described convex lens 21 are rectangular, are installed on the described vernier scale 2 by the draw-in groove 23 of being located at described vernier scale 2 tops.
Above-mentioned novel vernier caliper, the enlargement factor of described convex lens 21 is more than 2 times.
Above-mentioned novel vernier caliper in use, because the amplification of convex lens 21, make main scale 1 contact with vernier scale 2 part master calibration and vernier graduation be exaggerated, thereby make the operator can clearly tell vernier scale 2 and the highest scale of main scale 1 degree of registration, thereby improve the degree of accuracy of measuring.
