Abstract
The invention relates to a circular steel pipe diameter measuring tool. The circular steel pipe diameter measuring tool comprises a support and a measuring ruler. The support is arranged in one end of a circular steel pipe. The middle of the measuring ruler is rotationally arranged at one side, facing a corresponding end portion of the circular steel pipe, of the support, and the measuring ruler is attached to the end face of the circular steel pipe. According to the circular steel pipe diameter measuring tool of the invention, the measuring ruler is positioned at the end portion of the circular steel pipe through the V-shaped support; and the diameter of the circular steel pipe can be measured accurately through rotating the measuring ruler, and operation is convenient.
Description
Technical field
The present invention relates to a kind of round steel pipe diameter measurement instrument.
Background technology
For round steel pipe, when measuring its diameter, comparatively easy method is exactly that direct ruler is measured in its end, if the middle part that ruler does not have did not have the center of circle of steel pipe, then there is certain error in measurement data, above-mentioned metering system can only be estimated, and number of objects to be measured is normally more, therefore needs one comparatively convenient and measurement result diameter measurement instrument comparatively accurately.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, and provides a kind ofly to be convenient to measure and the higher round steel pipe diameter measurement instrument of accuracy, is specifically realized by following technical scheme:
A kind of round steel pipe diameter measurement instrument, comprise support, dip stick and indicia band, described is placed on inside, round steel pipe one end, and the middle part of described dip stick is arranged at the side of support towards round steel pipe corresponding end rotationally, and this dip stick and round steel pipe end face are fitted; Described support is the wishbone with three end points, and the two ends of indicia band are connected with the mid point of two poles of described wishbone respectively.
Described round steel pipe diameter measurement instrument, its further design be, the middle part of described dip stick is arranged on the middle part end points of support rotationally, and all the other two end points of support are provided with magnet and by magnet attraction on the inwall of round steel pipe end.
Described round steel pipe diameter measurement instrument, it designs further and is, described dip stick slides is provided with sliding sleeve, and this sliding sleeve side is provided with and notch, and described notch is arranged in the end of described round steel pipe.
Dip stick is positioned the end of round steel pipe by the present invention by wishbone, by wheel measuring chi, can carry out Measurement accuracy to the diameter of round steel pipe, comparatively convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is shift sleeve structure schematic diagram.
Embodiment
Below in conjunction with Figure of description and embodiment, the present invention is further described.
This round steel pipe diameter measurement instrument, comprises support 1, dip stick 2 and indicia band 4, and it is inner that support 1 is placed in round steel pipe 3 one end, and the middle part of dip stick 2 is arranged at the side of support towards round steel pipe corresponding end rotationally, and this dip stick and round steel pipe 3 end face are fitted.
Support 1 is for having the wishbone of three end points, the two ends of indicia band 4 are connected with the mid point of two poles of wishbone respectively, the middle part of dip stick is arranged on the middle part end points of support rotationally, and all the other two end points of support 1 are provided with magnet 11 and by magnet attraction on the inwall of round steel pipe end.
Dip stick 2 slides and is provided with sliding sleeve 21, this sliding sleeve side is provided with and notch 211, and notch is arranged in the end of round steel pipe.
In the middle part of dip stick and wishbone, end points junction is scale 0 point, and its figure is along two the ends distributions of scale 0 respectively to dip stick.
The length of two poles of wishbone is equal, when on the inwall that the two ends of wishbone are pulled on round steel pipe, make indicia band exceptionally straight, rotation measuring chi, when dip stick crosses the mid point of indicia band, now stop operating dip stick, read dip stick high scale 0 both sides respectively with the calibration data of contact position, steel pipe two ends, two data summations can be drawn the precision diameter of round steel pipe diameter.
Claims (3)
