Description

Technical Field

[0001] The utility model relates to the technical field of tree measuring tools, in particular to a tool for measuring the diameter of a tree. Background Art

[0002] Measuring tree diameter is a key task in ecology courses. Existing methods typically use a cloth tape measure wrapped around the diameter to read the diameter. However, trees are often quite large in diameter, and their shapes are often not perfectly round, but rather have many irregular protrusions and depressions. Therefore, the accuracy of the diameter obtained by using a cloth tape measure to measure the circumference and then back-calculate the diameter is not very high.

[0003] To solve the above problems, the patent document with announcement number CN206832164U discloses a tree diameter measuring ruler and a tree measuring tool, comprising a measuring ruler body, a first clamping arm, and a second clamping arm. The measuring ruler body has a first side wall and a second side wall, and the first side wall is provided with a slide extending along the length direction. The first clamping arm is hinged to the first side wall, and the rotation axis of the first clamping arm is substantially perpendicular to the first side wall. The second clamping arm is connected to a slider, which is accommodated in the slide and can slide along the slide. The second clamping arm can rotate relative to the measuring ruler body, and its rotation axis is substantially perpendicular to the first side wall. The tree measuring tool comprises a telescopic frame and the above-mentioned tree diameter measuring ruler, and the telescopic end of the telescopic frame is connected to the tree diameter measuring ruler. Both can directly and accurately measure the diameter of a tree at any position, conveniently and quickly.

[0004] However, the existing tree diameter measuring ruler has a relatively simple structure, and the length of the measuring ruler body is fixed, which cannot be used to test trees with larger diameters and has poor versatility. Utility Model Content

It is understandable that the above solution can be used in the structure of a tool for measuring the diameter of a tree.

[0023] According to this specific embodiment, a storage groove 112 is provided on one side of the measuring ruler 101, and a first scale area 113 is provided on the other side of the measuring ruler 101. The first clamping arm is rotatably provided at one end of the measuring ruler 101, and a slide groove 114 is provided through the storage groove 112. A first sliding seat 115 is slidably provided in the slide groove 114, and the second clamping arm is rotatably provided on the first sliding seat 115. After one side of the tree to be measured is fitted with the inner wall of the first clamping arm, the second clamping arm is slid in the slide groove 114 so that the inner wall of the second clamping arm is fitted with the other side of the tree to be measured. At this time, the position of the second clamping arm is the diameter of the current tree.

[0024] Among them, the measuring ruler 101 is provided with a mounting groove 116 at one end away from the first clamping arm, the extension arm 102 is slidably provided inside the mounting groove 116, and the extension arm 102 is provided with a second scale area 117 on a side close to the first scale area 113, and a placement groove 118 is provided on the side of the extension arm 102 away from the first scale area 113, and a sliding groove 119 is provided through the placement groove 118, and a second sliding seat 120 is slidably provided on the sliding groove 119, and the third clamping arm is rotatably provided on the second sliding seat 120, and two first fixing holes 121 are provided at both ends of the side of the extension arm 102 away from the placement groove 118, and two second fixing holes 122 are also provided at the end of the measuring ruler 101 away from the first clamping arm. The second fixing hole 122 is located on the side of the measuring ruler 101 away from the receiving slot 112, and the first fixing hole 121 and the second fixing hole 122 are both provided. When the second clamping arm 102 is adapted to the fixing clamp, when it is necessary to measure a tree with a larger diameter, the second clamping arm is rotated so that the second clamping arm is stored in the storage slot 112, the fixing clamp is removed, and the extension arm 102 is pulled so that the extension arm 102 slides in the installation slot 116. When the end of the extension arm 102 located inside the installation slot 116 slides to the second fixing clamping hole 122, the first fixing clamping hole 121 at the end of the extension arm 102 located inside the installation slot 116 corresponds to the second fixing clamping hole 122, and the fixed part completes the fixation of the extended extension arm 102. The third clamping arm is slid so that the tree to be measured is located between the first clamping arm and the third clamping arm, and the diameter of the tree to be measured is measured by the cooperation of the first scale area 113 and the second scale area 117. With the above structure, the measurement range is expanded through the setting of the extension mechanism, and the versatility is enhanced.

[0025] Secondly, the fixing posts 105 are fixedly provided at both ends of the mounting plate 103, and the disassembly and assembly handle 104 is provided on the side of the mounting plate 103 away from the fixing posts 105.

[0027] When using the tool for measuring the diameter of a tree of the present invention, after one side of the tree to be measured is fitted with the inner wall of the first clamping arm, the second clamping arm is slid in the sliding groove 114 so that the inner wall of the second clamping arm is fitted with the other side of the tree to be measured. At this time, the position of the second clamping arm is the current diameter of the tree. When it is necessary to measure a tree with a larger diameter, the second clamping arm is rotated so that the second clamping arm is stored in the storage groove 112, the fixing clamp is removed, and the extension arm 102 is pulled so that the extension arm 102 slides in the installation groove 116. When the extension arm 102 is located in the When one end inside the mounting slot 116 slides to the second fixing hole 122, the first fixing hole 121 at one end of the extension arm 102 located inside the mounting slot 116 corresponds to the second fixing hole 122, and the extended extension arm 102 is fixed by the fixing clamp. The third clamp arm is slid so that the tree to be measured is located between the first clamp arm and the third clamp arm, and the first scale area 113 and the second scale area 117 cooperate to complete the measurement of the diameter of the tree to be measured. With the above structure, the measurement range is expanded through the provision of the extension mechanism, and the versatility is enhanced.
