Description

Technical Field

[0001] The utility model relates to a device for measuring the diameter of a tree, belonging to the field of tree diameter measuring instruments. Background Art

[0002] The diameter at breast height of a tree refers to the diameter of the trunk at 1.3m from the ground. It is usually used as the basis for settlement of garden projects and is an important indicator for garden completion measurement. The existing tree diameter tape is generally a steel tape with a length of 2m and marked with diameter and length scales. It can measure the tree diameter at breast height in the range of 1-60cm. At present, in the garden completion measurement, technicians generally use a tree diameter tape to measure the position 1.3m from the ground, and then use the tree diameter tape to measure the tree diameter at breast height at that position. This method requires two people to work together, one of whom is fixed at the starting point of the measurement, and the other person pulls the tree diameter tape around the tree to read the tree diameter at breast height. Since the existing tree diameter tape is only 2m long, it can only measure trees with a breast diameter of less than 60cm at a time. If the tree has a breast diameter greater than 60cm, it needs to be measured in sections. The segmented measurement is prone to errors due to inconsistent starting positions and measurements not on the same horizontal line. In addition, it is easy to cut fingers and cause personal injury during the recovery of the steel tree diameter tape.

[0003] Therefore, the utility model provides a device for measuring the tree diameter at breast height safely and quickly, which can be operated by one person and is convenient to carry and suitable for trees of any size. Utility Model Content

[0034] Reference Figure 1-Figure 3 As shown, this embodiment provides a specific implementation method for a device for measuring the diameter of a tree, including a housing 10, a tape measure 20, a tape measure storage opening 30, and a laser measuring unit 40. The first surface 102 of the housing 10 is provided with a tape measure storage opening 30 for the tape measure 20 to enter and exit, and the laser measuring unit 40 is installed at the bottom of the housing 10. The device is held horizontally and the laser measuring unit 40 is used to measure the height of the device from the ground, which is displayed on the digital display screen 402. The device is moved up and down until the position 1.3m above the ground is measured; then the tape measure 20 is stretched to measure the tree diameter. The measuring method is as follows:

[0035] Among them, see Figures 1 to 5 The measuring tape 20 comprises a tape 201, a fixing portion 202 exposed outside the housing 10 and fixed to the tape 201 by riveting, and the fixing portion 202 is movable to pierce the surface layer of the tree, such as Figure 4 and Figure 5As shown, regardless of the tree species, whether it is a rough bark or a smooth bark, one end is fixed, and the tape 201 is continuously pulled out to wrap around the tree, and the rope is passed through the fixing portion 202 and reversely tightened, and the recovery switch 206 is pressed, and the tape 201 is closely attached to the surface of the tree, and the value of the tape 201 at the position of the fixing portion 202 is read, which is the tree's breast diameter, and is recorded, and the fixing portion 202 is released, and the recovery switch 206 is pressed to retract all the tapes 201, as shown in FIG. Figure 1 As shown, the tree diameter at breast height measurement is completed.

[0036] For more details, see Figures 3 to 7 The fixing portion 202 includes a locking portion 221, a concealing portion 222, and a rotating pin 223 connected to one end of the locking portion 221 and the concealing portion 222, and the rotating angle of the rotating pin 223 is 0°-360°;

[0037] When the locking portion 221, the concealing portion 222, and the rotating pin 223 are on the same horizontal plane, it is convenient to retract them into the housing 10, and the rotating pin 223 is prevented from being exposed to the outside and causing damage to the human body;

[0038] When the rotating needle 223 and the planes where the locking portion 221 and the concealing portion 222 are located are perpendicular to each other, the rotating needle 223 can be vertically pierced into the surface layer of the tree to achieve fixation, and can be pulled out after use.

[0039] For more details, see Figure 5 The side of the locking portion 221 facing away from the concealing portion 222 is provided with a notch 221 - 1 for the end of the measuring tape 20 to be inserted therein, and then a screw or rivet is used to vertically penetrate the locking portion 221 and the end of the measuring tape 20 from the top surface of the locking portion 221 downward in sequence.

[0040] For more details, see Figure 6 The rotating needle 223 comprises a head 223-1 and a needle body 223-3 fixed in the middle of the end surface of the head 223-1;

[0041] A symmetrical rotating shaft 223-2 is fixed on the outer surface of the needle body 223-3 near the head 223-1;

[0042] The end of the rotating shaft 223-2 is rotatably connected to one end of the locking portion 221 or the hiding portion 222, so that the head 223-1 is away from the surface of the locking portion 221 and the hiding portion 222, which facilitates the needle body 223-3 to be pulled out again after piercing the tree epidermis.

[0043] For further information, see Figure 7 The hidden portion 222 includes a horizontal portion 222-2 and a vertical portion 22-3 vertically fixed to one end of the horizontal portion 222-2;

A spring sheet 203 is installed on the inner wall of the tape measure housing 204, and a rolling shaft 207 is installed at the head end of the spring sheet 203 near the fixed column 205. One end of the tape 201 is wound around the fixed column 205, and the other end passes through the rolling shaft 207 and extends out along the tape measure storage port 30. For the specific structural principle, please refer to the application number CN202121253810.X. The name of the patent application is a measuring tape for construction engineering, with one-key recovery of the tape 201.

[0048] Among them, see Figures 1 to 8 , the laser measurement unit 40 includes a digital display screen 402 embedded in the side of the housing 10, and a switch 401 located next to the digital display screen 402;

[0049] It also includes a laser transmitter 403, a laser receiver 404, and a circuit board 405. The circuit board 405 is electrically connected to the digital display screen 402 and the switch 401. The circuit board 405 is located at the bottom of the housing 10. The ends of the laser transmitter 403 and the laser receiver 404 electrically connected to the circuit board 405 penetrate to the bottom surface of the housing 10 to be exposed to the outside.

[0050] The utility model operates the laser transmitter 403 to emit a laser beam by pressing the switch 401, and the laser beam is reflected back to the laser receiver 404 after contacting the ground, and is displayed on the digital display screen 402 after being measured by the circuit board 405. It is used to measure the distance without visual observation, and the operation is convenient.

[0051] Furthermore, the laser measurement unit 40 also includes a battery 406 electrically connected to the circuit board 405 .

[0052] See also Figure 3As a possible specific implementation of the utility model, a storage rope 50 can be hung at the bottom of the housing 10 away from the tape measure storage opening 30 to facilitate outdoor carrying.

[0053] See also Figure 2 As a possible specific implementation of the utility model, a plurality of protrusions 101 are provided on the back of the housing 10 away from the laser measurement unit 40 to increase the friction when holding by hand and improve the stability of holding by hand.
