Abstract
The utility model discloses a heavy type caliber rule with a meter of a measuring tool for measuring the length of a wide range. A dial gauge is installed on the caliber rule frame of the heavy type caliber rule with the meter, an internal dial plate of the dial gauge is inscribed with a decimal scale, an integer scale is inscribed on the caliber rule body, and the indicating type reading measurement is realized through a rack-and-gear driving mechanism. The measuring range is between 4500 milimeters and 1000 millimeters. The heavy type caliber rule with the meter not only fills the gap of a no indication type caliber rule with the meter measuring the length of the wide range of China.
Description
The utility model provides a kind of heavy dial caliper.
Heavy slide calliper rule of Xiao Shouing in the market, its range are generally between 450 millimeters to 1000 millimeters, and its reading part all adopts the vernier reading principle to carry out reading.This heavy vernier caliper shortcoming is as follows: precision is low, because its meter full scale is long, be subjected to the restriction of mask-making technology, so graduating accuracy is difficult to improve, the error of indication is bigger, it is by groove is come reading in addition, since be subjected to the influence of people's collimation error, the reading difficulty, and efficiency of measurement is low, and this heavy vernier caliper complex process, manufacture difficulty is big.So not only strengthened expense, and brought inconvenience to the user.
The purpose of this utility model is to overcome shortcomings such as the medium and heavy vernier caliper precision of prior art is low, reading is difficult, efficient is low, and a kind of precision height that is applicable to wide range, easily reading, heavy dial caliper that efficiency of measurement is high are provided.
Accompanying drawing 1 is former heavy vernier caliper front view.
Accompanying drawing 2 has provided front view of the present utility model.
Among the figure: (1) blade (2) tooth bar (3) chi frame
(4) indicating gauge (5) dial plate (6) pointer
Further specify drive connection of the present utility model and assembling below in conjunction with accompanying drawing Operating position.
Indicating gauge (4) is fixedly linked with chi frame (3), and the wheel and rack (2) of indicating gauge (4) is meshed, and tooth bar (2) is fixedly linked with blade (1).When slide calliper rule use to be measured, pulling chi frame (3), tooth bar (2) on the blade (1) is just stirred the internal gear rotation of indicating gauge (4), the internal gear rotation of indicating gauge (4) just drives pointer (6) rotation, pointer (6) just can indicate the decimal scale by dial plate (5), the gauger can read concrete measurement numerical value according to the decimal scale on integer scale on the blade (1) and the dial plate (5).
What need specify here is, the dial caliper of Xiao Shouing in the market, all be not heavy dial caliper, its range generally has following several specification all less than 450 millimeters: 0～100 millimeter, 0～125 millimeter, 0～150 millimeter, 0～200 millimeter, 0～300 millimeter.The dial caliper of wide range---be that heavy drive table slide calliper rule be can not see.
Claims (3)
1, a kind of heavy dial caliper that is applicable to wide range linear measure longimetry measurer, realize the measurement of indicating type reading by rack and-pinion mechanism, its range is between 450 millimeters to 1000 millimeters, feature of the present utility model is tooth bar (2) to be housed on the blade (1) and to be carved with the integer scale, and indicating gauge (4) is housed on the chi frame (3).
2, dial plate (5) and pointer (6) are arranged in the indicating gauge as claimed in claim 1 (4).
3, be carved with the decimal scale on the dial plate as claimed in claim 2 (5).
