Abstract
Description
Technical Field
[0001] This utility model relates to the field of tree diameter at breast height (DBH) observation technology, specifically to a split-type tree DBH fixed observation device. Background Technology
[0002] In the field of landscaping, after trees are introduced and planted, it is necessary to regularly observe and record the growth of their diameter at breast height (DBH) to keep track of their growth at any time.
[0003] In existing technologies, a diameter at breast height (DBH) measuring tape is commonly used to measure the growth of a tree's diameter at breast height (DBH). Most DBH measuring tapes on the market are handheld measuring tapes. By fixing one end of the tape to the marked point and keeping it close to the trunk (to avoid tangling with branches and leaves), the tape is wrapped around the trunk once and kept in place. The diameter scale at the point where the tape coincides with the starting point is then observed and read. However, most existing DBH measuring tapes are one-piece designs. When observing a large number of trees, if the tape is damaged, rusted, or the trees grow too fast and the tape is too short, the one-piece DBH measuring tape must be replaced entirely. This not only increases the measurement cost but also causes waste. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a split-type tree diameter at breast height (DBH) fixing and observation device. This solves the problem mentioned in the background art that when the ruler body of the existing technology is damaged, rusted, or the tree grows too fast and the ruler length is insufficient, the integrated DBH observation ruler can only be replaced as a whole, leading to increased measurement costs.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a split-type tree diameter at breast height (DBH) fixing and observation device, including a DBH ruler, a mounting box, a through groove, and a fixing component. One end of the mounting box is detachably connected to one end of the DBH ruler via a quick-release mechanism. The mounting box has a through groove that mates with the other end of the DBH ruler. The fixing component is disposed on the mounting box and is used to press against and fix the other end of the DBH ruler.
[0008] Furthermore, the quick-release mechanism includes a connecting shaft, a snap-fit plate, a snap-fit groove, and an abutment component. One end of the connecting shaft is fixedly connected to one end of the caliper, and the other end is embedded in the mounting box and rotatably engaged with the mounting box. One end of the snap-fit plate is fixedly connected to the other end of the connecting shaft. The mounting box has a sliding groove that mates with the snap-fit plate, and the mounting box has a snap-fit groove that mates with the snap-fit plate. The abutment component is disposed on the mounting box and is used to abut against and fix the snap-fit plate after it rotates.
[0009] Furthermore, the abutting assembly includes an abutting plate, a push rod, a push plate, and a first spring. The abutting plate is movably disposed within the mounting box. One end of the push rod passes through the mounting box and is fixedly connected to one end of the abutting plate. One end of the push plate is fixedly connected to the other end of the push rod. The two ends of the first spring are respectively fixedly connected to one end of the mounting box and one end of the push plate.
[0010] As a further embodiment of this solution, the fixing assembly includes a fixing plate, a pressing rod, a handle, a limiting plate, and a second spring. A slot is provided inside the mounting box, and the fixing plate is slidably disposed within the slot. One end of the pressing rod passes through the mounting box and is fixedly connected to one end of the fixing plate. The handle is fixedly connected to the other end of the pressing rod. Two limiting plates are symmetrically fixedly connected to both ends of the pressing rod. A limiting groove that mates with the limiting plates is provided inside the mounting box. Both ends of the second spring are fixedly connected to the inner wall of the limiting groove and one end of the limiting plate, respectively.
[0011] As a further improvement to this solution, the through groove is arc-shaped, and the inlet of the through groove is located on one side of the slide groove.
[0012] Based on the aforementioned scheme, a rubber pad is fixedly installed at one end of the fixing plate.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a split-type tree diameter at breast height (DBH) fixing and observation device, which has the following beneficial effects:
[0015] 1. In this utility model, through the cooperation of the Breast Diameter Meter, the mounting box, and the quick-release mechanism, the push plate is used to move the abutment plate out of the locking groove by hand. By driving one end of the Breast Diameter Meter to keep the locking plate corresponding to the sliding groove, the locking plate and the connecting shaft are driven into the mounting box. Rotating the Breast Diameter Meter drives the connecting shaft and the locking plate to rotate. Then, the push plate is released. During the process of the first spring returning to its original state, the push plate drives the abutment plate to move downward and abuts the locking plate, keeping the abutment plate fixed. This makes it easy to disassemble the Breast Diameter Meter, which is not only convenient to carry and transport, but also easy to replace.
[0016] 2. In this utility model, by using the mounting box and the fixing component together, the fixing plate is moved into the slot (without being blocked in the through slot) by holding the handle and pulling it away from the mounting box. The diameter at breast height (DBH) ruler is then placed around the tree with the other end passing through the through slot. The DBH ruler surrounds the tree to be measured. By releasing the handle, the limiting plate returns to its original position under the pull of the second spring. This causes the fixing plate to work with the rubber pad to firmly fix the part of the DBH ruler in the through slot, which is convenient for observing the DBH of the tree.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example
[0026] Please see Figures 1 to 6 A split-type tree diameter at breast height (DBH) fixing and observation device includes a DBH ruler 1, which is made of aluminum alloy and has graduations marked on it. It also includes a mounting box 2, a through groove 3, and fixing components.
[0027] One end of the mounting box 2 is detachably connected to one end of the thorax measuring tape 1 via a quick-release mechanism. The quick-release mechanism includes a connecting shaft 4, a snap-fit plate 5, a snap-fit groove 7, and an abutment assembly. One end of the connecting shaft 4 is fixedly connected to one end of the thorax measuring tape 1, and the other end is embedded in the mounting box 2 and rotatably engaged with the mounting box 2. One end of the snap-fit plate 5 is fixedly connected to the other end of the connecting shaft 4. The width of the snap-fit plate 5 is smaller than the diameter of the connecting shaft 4. The mounting box 2 has a sliding groove 6 that mates with the snap-fit plate 5, and the mounting box 2 also has a groove 6 that mates with the snap-fit plate 5. The matching snap-fit groove 7 is connected to the sliding groove 6. The snap-fit groove 7 is fan-shaped and circular with the axis of the connecting shaft 4. The other end of the snap-fit plate 5 is arc-shaped. By driving one end of the diameter gauge 1, the snap-fit plate 5 is kept in line with the sliding groove 6, and the snap-fit plate 5 and the connecting shaft 4 are driven into the mounting box 2 to prevent the snap-fit plate 5 from moving out of the mounting box 2. After the snap-fit plate 5 is in the snap-fit groove 7, by rotating the diameter gauge 1, the diameter gauge 1 drives the connecting shaft 4 and the snap-fit plate 5 to rotate, so that one end of the diameter gauge 1 is fixedly connected to the mounting box 2.
[0028] It should be added that the mounting box 2 has an arc-shaped recess, and a rubber layer is fixedly connected to the arc-shaped recess to support the tree to be observed. The sliding groove 6 is located at one end close to the arc-shaped recess, and one end of the diameter gauge 1 is marked with the "0" mark.
[0029] The abutment assembly is mounted on the mounting box 2 and is used to abut and fix the snap-fit plate 5 after it rotates. The abutment assembly includes an abutment plate 8, a push rod 9, a push plate 10, and a first spring 11. The abutment plate 8 is movably mounted inside the mounting box 2. A moving groove is provided inside the mounting box 2, and the abutment plate 8 slides against the inner wall of the moving groove. The moving groove is connected to the snap-fit groove 7. One end of the push rod 9 passes through the mounting box 2 and is fixedly connected to one end of the abutment plate 8. One end of the push plate 10 is fixedly connected to the other end of the push rod 9. An opening is provided on the push plate 10 to facilitate the operator's gripping of the push plate 10. The two ends of the first spring 11 are respectively connected to the mounting box. 2 is fixedly connected to one end of the push plate 10. By holding the push plate 10, the push plate 10 is pulled upward. The push plate 10 drives the push rod 9 to move upward, and the push plate 10 stretches the first spring 11. The push rod 9 drives the abutment plate 8 to move upward, so that the abutment plate 8 moves out of the locking groove 7 and is transferred to the moving groove. At this time, the locking groove 7 is not blocked by the abutment plate 8, and the locking plate 5 can be rotated. Then the push plate 10 is released. During the process of the first spring 11 returning to its original state, the push plate 10 drives the push rod 9 and the abutment plate 8 to move downward and abut the locking plate 5, keeping the abutment plate 8 fixed.
[0030] It should be added that when the first spring 11 is not subjected to the pulling force of the operator, the abutment plate 8 is in the locking groove 7;
[0031] The mounting box 2 has a through groove 3 that matches the other end of the diameter at breast height (DBH) ruler 1. The through groove 3 is arc-shaped, and the entrance of the through groove 3 is located on one side of the slide groove 6. The outer walls of the mounting box 2 are all flat. The other end of the DBH ruler 1 passes through the through groove 3, so that the DBH ruler 1 fits the mounting box 2 to form a shape that is close to a circle. At this time, the contact part between the other end of the DBH ruler 1 and the entrance of the through groove 3 is on the same plane as one end of the DBH ruler 1, so that the diameter at breast height of the tree can be observed.
[0032] A fixing assembly is mounted on the mounting box 2 to abut and fix the other end of the thorax measuring tape 1. The fixing assembly includes a fixing plate 12, a compression rod 14, a handle 15, a limiting plate 16, and a second spring 18. A slot 13 is provided inside the mounting box 2, and the fixing plate 12 is slidably disposed in the slot 13. A rubber pad 19 is fixedly provided at one end of the fixing plate 12. One end of the compression rod 14 passes through the mounting box 2 and is fixedly connected to one end of the fixing plate 12. The handle 15 is fixedly connected to the other end of the compression rod 14. Two limiting plates 16 are symmetrically fixedly connected to both ends of the compression rod 14. A limiting groove 17 that mates with the limiting plate 16 is provided inside the mounting box 2. The two ends of the second spring 18 are fixedly connected to the inner side wall of the limiting groove 17 and one end of the limiting plate 16, respectively. By holding the handle 15 and pulling it away from the mounting box 2, the handle 15 moves the squeezing rod 14. The squeezing rod 14 simultaneously moves the fixing plate 12 and the limiting plate 16. The two limiting plates 16 stretch the two second springs 18 respectively, while the fixing plate 12 moves into the slot 13 (not blocked in the through slot 3). When the other end of the diameter at breast height (DBH) ruler 1 passes through the through slot 3 and the DBH ruler 1 surrounds the tree to be measured, by releasing the handle 15, the limiting plate 16 returns to its original position under the pull of the second spring 18. The limiting plate 16 moves the squeezing rod 14, the handle 15 and the fixing plate 12 toward the through slot 3. In this way, the fixing plate 12, together with the rubber pad 19, presses and fixes the part of the DBH ruler 1 in the through slot 3, which is convenient for observing the DBH of the tree.
[0033] It should be added that, since there may be protrusions or dents on the trees, multiple measurements can be taken and the average value taken.
[0034] Working principle: When measuring the diameter at breast height (DBH) of a tree, this split-type tree DBH fixing and observation device involves holding the push plate 10 and pulling it upwards. The push plate 10 drives the push rod 9 to move upwards, and the push plate 10 stretches the first spring 11. The push rod 9 drives the abutment plate 8 to move upwards, causing the abutment plate 8 to move out of the locking groove 7 and into the moving groove. At this time, the locking groove 7 is not blocked by the abutment plate 8. By driving one end of the DBH ruler 1 to keep the locking plate 5 corresponding to the sliding groove 6, the locking plate 5 and the connecting shaft 4 are driven to move. Enter the mounting box 2 to prevent the snap-fit plate 5 from moving out of the mounting box 2. After the snap-fit plate 5 is in the snap-fit groove 7, rotate the Breast Diameter Ruler 1. The Breast Diameter Ruler 1 drives the connecting shaft 4 and the snap-fit plate 5 to rotate. Then release the push plate 10. During the process of the first spring 11 returning to its original state, the push plate 10 drives the push rod 9 and the abutment plate 8 to move downward and abut the snap-fit plate 5, keeping the abutment plate 8 fixed. This makes it easy to disassemble the Breast Diameter Ruler 1, which is not only easy to carry and transport, but also easy to replace.
[0035] By holding the handle 15 and pulling it away from the mounting box 2, the handle 15 moves the squeezing rod 14. The squeezing rod 14 simultaneously moves the fixing plate 12 and the limiting plate 16. The two limiting plates 16 stretch the two second springs 18 respectively, while the fixing plate 12 moves into the slot 13 (not blocked in the through slot 3). The diameter at breast height (DBH) ruler 1 is wrapped around the tree, with one end passing through the through slot 3. After the other end of the DBH ruler 1 passes through the through slot 3 and the DBH ruler 1 surrounds the tree to be measured, by releasing the handle 15, the limiting plate 16 returns to its original position under the pull of the second spring 18. The limiting plate 16 moves the squeezing rod 14, the handle 15, and the fixing plate 12 toward the through slot 3. In this way, the fixing plate 12, together with the rubber pad 19, presses and fixes the part of the DBH ruler 1 in the through slot 3, which is convenient for observing the DBH of the tree.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
