A circle is determined through three points in the application, and meanwhile a plurality of positioning blocks 2 are arranged on the inner side of the pipeline 1 for stabilizing the central disc 4, so that the central disc 4 is coaxial with the pipeline 1. The positioning blocks 2 have the same size and structure, and the elastic members 10 have the same elastic modulus and length. When the support rods 8 are plugged into the pipeline 1, the movement distances of the positioning blocks 2 relative to the support rods 8 are the same, that is, the positioning blocks 2 slide along the sliding grooves 9 by the same distance. In the present application, the elastic member 10 having a larger elastic modulus may be selected to reduce the time for the elastic member 10 to reach the steady state. The spout 9 is seted up in the bracing piece 8 free end, and elastic component 10 one end fixed connection is at the tank bottom of spout 9, and the other end is fixed on locating piece 2, and the setting of laminating of locating piece 2 and spout 9 also, the lateral wall that also is locating piece 2 and spout 9 does not have the clearance to the accuracy of location has been guaranteed.

As a specific embodiment of the pipeline dimension measuring tool provided by the present invention, please refer to fig. 1, a plurality of support rods 8 are arranged along the radial direction of the central plate 4. The central disc 4 is regular round, and the circle center of the central disc 4 is coincided with the axis of the pipeline 1 through a plurality of support rods 8. In order to improve the stability of the central disc 4, the included angles between the plurality of support rods and the outer edge of the central disc 4 are the same, and the support rods 8 are arranged along the radial direction of the central disc 4, i.e. the extension lines of the lengths of the support rods 8 pass through the center of the central disc 4. After all filling in the inner wall of pipeline 1 with a plurality of locating pieces 2, with the laminating of dipperstick 5 at the tip of pipeline 1, the accessible dipperstick 5 and the contact condition of pipeline 1 judge whether the axis setting of perpendicular pipeline 1 of center disk 4 can rotate certain angle with dipperstick 5 to verify the result of measuring before. Dipperstick 5 is transparent finished piece, and when the tip of dipperstick 5 laminating at pipeline 1, sight vertical measurement chi 5 to according to scale 6 on dipperstick 5, read pipeline 1's internal diameter and external diameter respectively, after the measurement is accomplished, with the bracing piece 8 follow pipeline 1 in take out can, the device need not the fastening, the installation with dismantle conveniently, and have higher measurement accuracy.

As a specific embodiment of the pipeline size measuring tool provided by the present invention, please refer to fig. 1, scale 6 is provided on the measuring scale 5, and the scale 6 is symmetrically distributed on both sides of the measuring scale 5. Dipperstick 5 is rectangular shape, and the nodical point of two diagonal of dipperstick 5 is the central point promptly, and the central point of dipperstick 5 rotates to be connected on central disc 4, and dipperstick 5 rotates along the axis of central disc 4 to be set up. The scale 6 on the dipperstick 5 sets up in the middle part, sets up along the long limit of dipperstick 5. The scales 6 on the measuring scale 5 are symmetrically distributed on both sides of the measuring scale 5, and the functions of the scales are calibration. After central disk 4 is stable, through reading the numerical value of dipperstick 5 both sides respectively, when two numerical values are equal, explain central disk 4 and the coaxial setting of pipeline 1, can rotate certain angle with dipperstick 5, read two numerical values once more and check to guarantee the measuring accuracy. When the readings on the two sides of the measuring ruler 5 are different, the central disc 4 and the pipeline 1 are not coaxial, the position of the positioning block 2 can be adjusted, or the central disc 4 is shaken. By symmetrically arranging the scales 6 on both sides of the measuring scale 5, the accuracy of the measurement can be ensured.

As a specific embodiment of the pipeline size measuring tool provided by the present invention, please refer to fig. 1, the measuring scale 5 is rotated and disposed on one side of the central plate 4 away from the supporting rod 8. When using, at first fill in pipeline 1 with a plurality of locating pieces 2 in, the terminal surface and the laminating of pipeline 1 of locating piece 2 set up, can be coaxial with pipeline 1 in order to guarantee that center plate 4 at first carries out the range estimation, then carries out slight rocking, ensures that a plurality of locating pieces 2 all closely laminate on the inner wall of pipeline 1. The positioning blocks 2 are abutted against the inner wall of the pipeline 1 through the elastic pieces 10, and after the positioning blocks 2 are stably attached to the inner wall of the pipeline 1, if the positioning blocks 2 are not easy to shake, the positioning of the positioning blocks 2 is good.
