The hook is of an S-shaped structure formed by bending a stainless steel sheet with the length of 3.5cm, the width of 1cm and the thickness of 0.1 cm. The utility model discloses a when the steel ruler measures the tree footpath around trees round, the couple is used for hooking on the steel ruler, under the effect of wind spring, around steel ruler and the tape measure box on the tree can not drop, a tree is equipped with a monitoring tape measure, and when trees are long thick, the steel ruler also can follow the elongation, and the staff need not draw the ruler volume again, as long as direct reading alright, the utility model has the characteristics of simple structure, convenient to use.
Description
Technical Field
The utility model relates to a forestry, fruit tree, the measuring tool that horticulture research is grown are particularly useful for the monitoring tape measure that needs decide trunk, fixed point, the forest growth observation of location for a long time.
Background
The growth of the breast height of the forest is one of the most important indexes for researching the growth of the forest. Forestry researchers all adopt artifical immediately with commodity survey tree girth ruler to carry out the chest diameter to trees and measure. In long-term multiple measurements every year, even if the same person holds the same commodity tree measuring girth ruler for measurement, the measurement cannot be guaranteed to be carried out at the same position of the tree, only extensive measurement is carried out, data acquisition is inaccurate, the breast diameter is suddenly large and small, human errors are large or even violate growth rules, the situation that the length is longer and smaller is sometimes caused, labor cost is consumed, and monitoring is inconvenient. In the research and observation requiring long-term plant fixing, fixed point and positioning of the forest, a great amount of necessary tools are needed, and the method has great application market prospect.
SUMMERY OF THE UTILITY MODEL
In view of this, for solving the problem among the above-mentioned prior art, the utility model provides a convenient to use's accurate long-term monitoring tape measure of trees growth.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
the utility model provides an accurate long-term monitoring tape measure of trees growth, includes tape measure box, wind spring and steel ruler, and the one end of steel ruler is around in the tape measure box, and the other end is located outside the tape measure box, and the wind spring is established and is used for making the steel ruler part that pulls out the tape measure box to reset in the tape measure box in, the one end of steel ruler is connected with the couple, and when the steel ruler measured the tree footpath around trees round, the couple was used for hooking on the steel ruler.
Further, the depth of the hook groove of the hook is not less than the width of the steel ruler.
Further, the hook is of an S-shaped structure.
Furthermore, the hook is formed by bending a metal sheet with the length of 3.5cm, the width of 1cm and the thickness of 0.1 cm.
Further, the hook is made of stainless steel.
The utility model has the advantages that: the utility model discloses a when the steel ruler measures the tree footpath around trees round, the couple is used for hooking on the steel ruler, under the effect of wind spring, around steel ruler and the tape measure box on the tree can not drop, a tree is equipped with a monitoring tape measure, and when trees are long thick, the steel ruler also can follow the elongation, and the staff need not draw the ruler volume again, as long as direct reading alright, the utility model has the characteristics of simple structure, convenient to use.
Drawings
The invention will be further explained with the aid of the accompanying drawings, in which, however, the embodiments in the drawings do not constitute any limitation to the invention, and for a person skilled in the art, without inventive step, further drawings can be obtained in accordance with the following drawings:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged schematic view of the hanger shown in fig. 1.
In the figure: 1. a tape measure box; 2. A steel ruler; 3. Hooking; 4. a ruler head pull ring.
Detailed Description
In order to make the technical solutions of the present invention better understood, the following detailed description of the present invention is provided with reference to the accompanying drawings and specific embodiments, and it should be noted that the embodiments and features of the embodiments of the present invention can be combined with each other without conflict.
As shown in fig. 1, a tape measure for accurately monitoring the growth of trees for a long time comprises a tape measure box 1, a coil spring and a steel rule 2, wherein one end of the steel rule 2 is wound in the tape measure box 1, the other end of the steel rule is positioned outside the tape measure box, the coil spring is arranged in the tape measure box 1 to reset the steel rule part pulled out of the tape measure box into the tape measure box 1, one end of the steel rule 2 is connected with a hook 3, and when the steel rule measures the diameter of the trees for one circle around the trees, the hook 3 is used for hooking the steel rule.
Couple 3 in this patent can the riveting in the one end of steel ruler 2, also can remain the chi head pull ring 4 of current steel ruler outer end, and couple 3 adopts swing joint's form, articulate alright with chi head pull ring 4. For example, the hook can be designed in such a way that the hook is bent into an S-shaped structure by a stainless steel sheet with the length of 3.5cm, the width of 1cm and the thickness of 0.1cm, and as shown in fig. 2, the depth of a hook groove of the hook is not less than the width of a steel ruler. The S-shaped hook 3 actually has two hook grooves, one hook groove is hung on the tape head pull ring 4 of the tape measure, and the other hook groove is hung on the steel tape 2.
In this patent, the tape measure including tape measure box 1, coil spring and steel chi 2 is prior art, and this patent has set up a couple on the basis of current tape measure. The measuring tape is mainly used for measuring the diameter of the breast of the tree in different growth periods, so that in order to realize the positioning measurement of the diameter of the breast of the tree, one tree is required to be matched with one measuring tape, the measuring tape is not taken down after the tree is measured for the first time, under the action of the coil spring, the steel ruler wound on the tree and the ruler box can not fall off, so the design is only that the cost of the tape measure of the utility model is very low, the existing tape measure for measuring the tree, the tape measure box is not provided with a locking switch, the cost is very low, and wholesale only needs 1.6 yuan, so that the accurate detection of positioning can be completely realized, because add the couple, there is the error in actual reading value and actual size, can correct reading error according to the actual size of couple, for example, to the couple of this patent, actual reading value plus the value of testing 1.5cm is exactly the measured value of trees diameter.
The utility model discloses effectively solved artifical instant survey data and appeared the coarse reality problem in a plurality of error sources, this patent is applicable to the long-term monitoring that is greater than 3cm above tree footpath growth. According to the measurement and calculation of the growth rate of the current forest trees, the monitoring of the eucalyptus growing fastest can be continuously carried out for 34 years, and the pine trees grow for 68 years.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
