Abstract
The utility model discloses a vernier caliper with 50 graduations. The vernier caliper is composed of a main scale and a vernier scale, wherein the vernier scale is provided with 50 graduations, and the length of each graduation is 1.02mm. From the first graduation line on the rightmost of the vernier scale, reading marks of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 are marked from the right to the left at intervals of 5 graduations. The vernier caliper disclosed by the utility model is easier to be read without changing the measurement accuracy, and more practical and more convenient when measuring the length.
Description
Technical field
The utility model belongs to the survey instrument scope, relates to a kind of vernier caliper, particularly a kind of 50 calibration vernier calipers.
Background technology
Vernier caliper is the dimensional measuring instrument of using always, all indicates the reading groove on the main scale of vernier caliper and the vernier scale.For example, the minimum calibration of 50 calibration vernier caliper main scales commonly used is 1mm, and the length overall of 50 calibration equals 49mm on the vernier scale, and promptly the length of a calibration is merely 0.98mm on the vernier scale.Because the groove on the vernier scale is closeer, when carrying out linear measure longimetry with vernier caliper, the not so good people of eyesight has certain reading difficulty or misreads number easily.
Summary of the invention
The technical matters that the utility model will solve is a kind of 50 calibration vernier calipers that can make things convenient for reading of exploitation, and the ruling span on its vernier scale is bigger.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of 50 calibration vernier calipers of the utility model are made up of main scale and vernier scale, have 50 calibration on the said vernier scale, and the length of each calibration is 1.02mm.The minimum calibration of said main scale still is 1mm.
Rightmost article one groove from the said vernier scale, right-to-left whenever indicate the groove reading mark of " 0 ", " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 ", " 0 " successively at a distance from 5 calibration.
The number reading method of the utility model vernier caliper is similar with the number reading method of vernier caliper commonly used: the reading (reading a millimeter integer) of reading the indicated main scale of the left side on the vernier scale " 0 " groove earlier; Judge that again which root groove on the vernier scale overlaps with groove on the main scale; Read corresponding reading on the vernier scale, be added in the back of main scale reading.
Through technique scheme, the utlity model has following beneficial effect: identical with the precision of 50 calibration vernier calipers commonly used, the groove on its vernier scale is comparatively sparse simultaneously, thereby easier reading, and is more practical and convenient when measuring length.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Accompanying drawing is the synoptic diagram of a kind of 50 calibration vernier calipers of the utility model.
Among the figure: 1. main scale, 2. vernier scale
Embodiment
As shown in the figure, a kind of 50 calibration vernier calipers of the utility model are made up of main scale 1 and vernier scale 2, have 50 calibration on the said vernier scale 2, and the length of each calibration is 1.02mm.The minimum calibration of said main scale 1 still is 1mm.
Rightmost article one groove from the said vernier scale 2, right-to-left whenever indicate the groove reading mark of " 0 ", " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 ", " 0 " successively at a distance from 5 calibration.
During with the said vernier caliper measurement length of the utility model; Read the millimeter integer reading of the indicated main scale 1 of the left side on the vernier scale 2 " 0 " groove earlier; Judge that again which root groove on the vernier scale 2 overlaps with groove on the main scale 1, read corresponding reading on the vernier scale 2, be added in the reading back of main scale 1.
The measuring principle of the utility model 50 calibration vernier calipers is following: when vernier caliper two measuring claws close up; " 0 " groove of " 0 " groove on vernier scale 2 left sides and main scale 1 overlaps, and " 0 " groove on vernier scale 2 the right just in time overlaps with the 51mm groove of main scale 1.Vernier scale several left the 2nd grooves in 2 the right this moment (reading is the 0.02mm place) are at the 0.02mm place, the left side of the 50mm of main scale 1 groove.When measuring thickness and be the object of 0.02mm, vernier scale 2 0.02mm that moves right, the 2nd groove in vernier scale 2 the right this moment just in time overlaps with the 50mm groove of main scale 1, and the reading of vernier caliper is 0.02mm.The number reading method of all the other length by that analogy.
