Specific embodiment

The utility model is described in further detail With reference to embodiment.

As shown in Figs. 1-2, as one of specific embodiment of the utility model, Diameter measure tool, including rolling Disk 10 rotates coaxially the first label component for being connected to 10 center of rolling disk, is fixed on the second label component of rolling disk 10；Rolling disk 10 The view field axial along rolling disk 10 is S1, and the first label component is S2 along the axial view field of rolling disk 10, and the part S2 is located at Outside S1.

In use, hand-held first label component, is close to trunk for 10 side of rolling disk, rolling disk 10 is rolled along trunk sagittal plane One week, the label of record the first label component marked last folder be overlapped number and two of the second label component label Angle.

Label and the second label label of the component corresponding label coincidence number of statistics the first label component are crossed with angle, The tree-walk that trunk can be calculated in conjunction with the radius of rolling disk 10 avoids the multiple pull of tape measure and damages using tape measure is not necessarily to, and uses When hand-held second label component, one hand completes operation, simple to operate.

First label component includes substrate 20, and substrate 20 is circle, and substrate 20 is equipped with calibration points 30, and calibration points 30 are with rolling disk 10 central axes are that axis is angularly distributed.

Calibration points 30 with rolling disk 10 for central axes are set, and calibration points 30 are by 10 equal portions of rolling disk, second convenient for during Reading of the component relative to 30 angle of calibration points is marked, calculation amount is reduced, improves testing precision.

Substrate 20 is equipped with level meter 40.

By the way that level meter 40 is arranged, when test, level is adjusted using level meter 40；Level meter 40 is set on substrate 20, Hand-held substrate 20, level meter 40 is static relative to substrate 20, makes tool holding horizontal in test process, avoids due to level meter 40 Setting causes monitoring result there are error with rotation on rolling disk 10, and measurement result accuracy is high.

Second label component includes the first pointer 50, and the first pointer 50 is fixedly connected with rolling disk 10.

First pointer, 50 head is thinner, is directed toward accurate.

It further include the column 60 for being coaxially fixed on rolling disk 10, the first label component is connected by column 60 and the rotation of rolling disk 10 It connects, the first pointer 50 is fixedly connected with column 60.

In test process, rolling disk 10 drives the rotation of the first pointer 50 by column 60, is rolled in conjunction with the statistics of calibration points 30 The turnning circle of disk 10 calculates the tree-walk of trunk further according to the radius of rolling disk 10.

It further include the metal clips 70 for being used to stop the first pointer 50 being set on substrate 20.

First pointer, 50 per revolution can contact primary with metal clips 70 and the deformation of metal clips 70 is made to issue the sound, The number that the sound that the first pointer 50 is contacted with metal clips 70 sounds is counted in test process, and 50 phase of the first pointer can be obtained It is easy to use for the number of revolutions of calibration points 30.

The diameter of rolling disk 10 is 12cm, if before test, the first pointer 50 is aligned after first calibration points 30 counterclockwise Test is completed in rotation, and elastic slice issues two peals, and the first pointer 50 is directed at second calibration points 30, then the tree-walk of trunk is at this time 2 × 12cm+1/12 × 12cm, i.e. 25cm.

It further include the transparent outer cover 80 for covering in substrate 20；Transparent outer cover 80 and substrate 20 enclose inner cavity；Calibration points 30, One pointer 50 is located in inner cavity.

Calibration points 30, the structures such as the first pointer 50 in inner cavity are protected using transparent outer cover 80, prevent corresponding component by Damage.

Still another embodiment as the utility model as shown in Figure 3 further includes be rotationally connected with column 60 the Two pointers 90 and gear transmission part for being driven between the first pointer 50 and the second pointer 90, the angular speed of the first pointer 50 It is equal to the number of calibration points 30 with the ratio between the angular speed of the second pointer 90.

Gear transmission part is the drive mechanism of wrist-watch in the prior art, the angular speed of the first pointer 50 and the second pointer 90 The ratio between angular speed be equal to the numbers of calibration points 30, the first pointer 50 rotates one week, and the second pointer 90 turns to and the first pointer The identical next scale of 50 rotation directions, the turnning circle of the first pointer 50 is recorded with this, is directly read, and without statistics, is made With convenient, the first pointer 50, long service life will not be worn.

The diameter of rolling disk 10 is 12cm, if the first pointer 50 is overlapped at 12 scale with the second pointer 90 before test, the The number that the ratio between angular speed of the angular speed of one pointer 50 and the second pointer 90 is equal to calibration points 30 is 12, if the second pointer 90 is read Number is 2, and the second pointer 90 reading is 6, then the tree-walk of trunk is 2 × 12cm+6/12 × 12cm, i.e. 30cm at this time.

As the another specific implementation direction of the utility model, substrate 20 is square, and substrate 20 is equipped with calibration points 30, is carved Degree point 30 is angularly distributed using the central axes of rolling disk 10 as axis.

Substrate 20 can also be other irregular shapes, it is only necessary to which calibration points 30 are angularly divided using the central axes of rolling disk 10 as axis Cloth.

There is longer straight flange at 20 both ends of substrate of square, convenient for hand-held.

The diameter of rolling disk 10 can be arranged according to different test scenes.

Above embodiment is only the certain preferred embodiments of the utility model, cannot limit the utility model with this The range of protection, the variation and replacement of any unsubstantiality that those skilled in the art is done on the basis of the utility model Belong to the utility model range claimed.
