Abstract
A diameter tape for measuring the trunk diameter of trees relates to a measuring tool. The problem that a measuring result of the existing tree trunk diameter measuring diameter tape needs to be manually read and the accuracy of a read result is affected by the working state of staff is solved. The diameter tape comprises a tape body, a gear, an encoding disk, a counter, a decoder and a display. A plurality of positioning holes are evenly distributed on a tape measure of the tape body along the length direction, and the distance between two adjacent positioning holes is equal to the arc length between the centers of two adjacent roots on the gear. The gear is fixed at an outlet inside a shell of the tape body through a fixed shaft. The encoding disk, the counter and the decoder are fixed in the shell. The display is fixed on the upper surface of the shell. The encoding disk is used for detecting the rotation angle of the gear. A signal output end of the encoding disk is connected with a counting signal input end of the counter, a data signal output end of the counter is connected with a decoding signal input end of the decoder, and a decoding signal output end of the decoder is connected with a display signal output end of the display. The diameter tape of the utility model is applied to the field of measurement.
