A kind of vernier caliper detected for electric transmission pole tower material
The utility model relates to a kind of vernier caliper, especially a kind of vernier caliper detected for electric transmission pole tower material.
Existing vernier caliper can only accomplish general commercial measurement work, although usable range is more wide in range, but the data of some routines can only be measured, some industries having special measurement to require are often inapplicable, also be like this in the context of detection of electric transmission pole tower material, there is no a kind of detection vernier caliper that can be special.
Summary of the invention
In order to overcome the defect that prior art exists, the utility model provides a kind of vernier caliper detected for electric transmission pole tower material, and this vernier caliper not only as routine measurement purposes, and can be specifically designed to the detection of electric transmission pole tower material.
The utility model solves the technical scheme that its technical matters adopts: a kind of vernier caliper detected for electric transmission pole tower material, comprise main scale, vernier scale and survey leg, it is characterized in that: described main scale is provided with the two rows scale of same starting point, the two rows scale being respectively equipped with two different starting points established by described vernier scale, the profile of described survey leg is cone, the inner side surveying leg is plane, described survey leg is also marked with the high-low limit size scale numerical value in conventional aperture.
Further, described survey leg is the cone of 3/5.
As preferably, two different starting points set by described vernier scale stagger 5mm mutually.
As preferably, the precision of described main scale and vernier scale marking is 0.05mm and 1mm two kinds.
The beneficial effects of the utility model are: this vernier caliper can meet all critical sizes of inspection iron tower in power transmission line material especially angle steel simultaneously, comprise that limb is wide, thickness, aperture, pitch-row, accurate distance and end distance, simple and quick, checkability can be improved significantly.

In figure, 1. survey leg, 2. main scale, 3. vernier scale.
The technical matters solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with accompanying drawing and embodiment, are further described the utility model.Should be appreciated that embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, the main scale 2 of this vernier caliper is provided with the two rows scale of same starting point, the two rows scale being respectively equipped with two different starting points established by described vernier scale 3, can be wide to the limb of angle steel respectively by above-mentioned 3 start index, reading is carried out when pitch-row and accurate distance, the profile of the survey leg 1 of vernier caliper is cone, the inner side surveying leg 1 is plane, not only can retain the function that leg 1 surveyed by traditional slide calliper rule thus, and the wide and thickness of the limb detecting tower material can be specifically designed to and measure aperture, distance between Kong Yukong, the distance in hole and face, described survey leg 1 is also marked with the high-low limit size scale numerical value in conventional aperture, the deviation in aperture can be measured whether in critical field value, the precision set of vernier caliper is 0.05mm and 1mm two kinds of precision, scale is more clear, facilitate reviewer's reading.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendment, on an equal basis replacement and improvement etc. done within spirit of the present utility model and principle, all should drop within protection domain of the present utility model.
