Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant quadrat collection technology, and in particular to a foldable portable herb quadrat frame. Background Technology
[0002] Herbaceous vegetation is one of the most important ecosystems on Earth, playing multiple roles such as water conservation, soil and water retention, maintaining biodiversity, and ecological balance. Surveys of herbaceous plant communities are essential for scientific research activities such as vegetation baseline surveys, biological resource surveys, biodiversity surveys, and ecological assessments. The quadratic method is the most commonly used method for community surveys, enabling rapid and accurate assessments of community structure, species diversity, and biomass.
[0003] During community surveys, herbaceous quadrats are the most numerous, typically measuring 1m x 1m. Currently, a simple method for marking herbaceous quadrats is to roughly demarcate them using tools like measuring tapes, which suffers from inaccurate boundaries and non-standardized quadrats. Another method uses more standardized herbaceous quadrat samplers, often constructed from PVC pipes, wooden or plastic strips, or steel telescopic rods. These are often complex to install, cumbersome to operate, difficult to fold, and space-consuming, making them inconvenient to carry and inefficient when surveying large numbers of herbaceous quadrats. Therefore, we propose a foldable, portable herbaceous quadrat frame. Utility Model Content

A first limiting rod 75 is movably connected to the fixed column 74. The height of the first fixed column 74 is greater than the thickness of the first limiting rod 75. The first limiting rod 75 can rotate around the first fixed column 74 and can also slide up and down along the first fixed column 74. A first limiting hole 76 is provided at the end of the first limiting rod 75 away from the first fixed column 74. The first limiting hole 76 is adapted to both the first limiting column 71 and the second limiting column 72.

The third limiting post 81 and the second fixing block 83 are both fixedly connected to the third connecting rod 3. The fourth limiting post 82 is fixedly connected inside the second limiting groove 6. A second fixing post 84 is fixedly connected to the top of the second fixing block 83. A second limiting rod 85 is movably connected to the second fixing post 84. The height of the second fixing post 84 is greater than the thickness of the second limiting rod 85. The second limiting rod 85 can rotate around the second fixing post 84 and can also slide up and down along the second fixing post 84. A second limiting hole 86 is provided at the end of the second limiting rod 85 away from the second fixing post 84. The second limiting hole 86 is adapted to both the third limiting post 81 and the fourth limiting post 82. The end of the second limiting rod 85 where the second limiting hole 86 is located is adapted to the second limiting groove 6.
[0024] It should be noted that this utility model is a foldable, portable herbal-shaped frame. In use, firstly, under the action of the first connecting member 9 and the second connecting member 10, the first connecting rod 1, the second connecting rod 2, the third connecting rod 3, and the fourth connecting rod 4 are rotated, causing the folded first connecting rod 1, the second connecting rod 2, the third connecting rod 3, and the fourth connecting rod 4 to unfold, forming an approximately square shape. Figure 2 As shown, the first limiting rod 75 and the second limiting rod 85 are then slid upwards on the first fixed post 74 and the second fixed post 84, respectively, until the first limiting hole 76 and the second limiting hole 86 are completely disengaged from the first limiting post 71 and the third limiting post 81, respectively. Then, the first limiting rod 75 and the second limiting rod 85 are rotated so that the end of the first limiting rod 75 containing the first limiting hole 76 rotates above the second limiting post 72, and the end of the second limiting rod 85 containing the second limiting hole 86 rotates above the fourth limiting post 82. Finally, the first limiting rod 75 and the second limiting rod 85 are... The rods slide downwards on the first fixed post 74 and the second fixed post 84 respectively. At this time, the first limiting rod 75 and the second limiting rod 85 are respectively embedded in the first limiting groove 5 and the second limiting groove 6, while the first limiting hole 76 and the second limiting hole 86 are respectively fitted onto the second limiting post 72 and the fourth limiting post 82. This restricts the first connecting rod 1, the second connecting rod 2, the third connecting rod 3, and the fourth connecting rod 4, preventing them from rotating. This forms a standard square herbaceous frame, as shown below. Figure 1 As shown, this can be used to frame herbaceous quadrats. After the herbaceous quadrat survey is completed, the first limiting rod 75 and the second limiting rod 85 slide upwards on the first fixing post 74 and the second fixing post 84, respectively, until the first limiting hole 76 and the second limiting hole 86 are completely disengaged from the second limiting post 72 and the fourth limiting post 82, respectively. Then, rotate the first limiting rod 75 and the second limiting rod 85 so that the end of the first limiting rod 75 with the first limiting hole 76 rotates above the first limiting post 71, and the end of the second limiting rod 85 with the second limiting hole 86 rotates above the third limiting post 81. Then, slide the first limiting rod 75 and the second limiting rod 85 downwards on the first fixing post 74 and the second fixing post 84, respectively. At this time, the first limiting hole 76 and the second limiting hole 86 are respectively fitted onto the first limiting post 71 and the third limiting post 81, thus restoring the original position. Figure 2 The state shown allows for the restriction of contact between the first connecting rod 1, the second connecting rod 2, the third connecting rod 3, and the fourth connecting rod 4. Then, under the action of the first connecting member 9 and the second connecting member 10, the first connecting rod 1, the second connecting rod 2, the third connecting rod 3, and the fourth connecting rod 4 can be rotated to fold them, i.e., by pushing... Figure 2The two opposite corners of the square in the design allow the sample frame to be folded into a rhombus. Compared to existing foldable portable herb sample frames, this invention is simple to operate, easy to carry and store, and faster and more efficient when dealing with a large number of herb sample plots.
