Description

Technical Field

[0001] This utility model relates to the field of quadrat frame technology, specifically a foldable and retractable quadrat frame. Background Technology

[0002] Quadrats are a commonly used survey tool in ecological research. They are usually rectangular frames made of metal, wood, or plastic and are used to define standardized sampling areas in vegetation surveys. By placing quadrats randomly or systematically in the target area, researchers can count parameters such as the species, quantity, cover, and frequency of plants within the frame, and then analyze community structure, species diversity, and spatial distribution patterns.

[0003] A search revealed a portable, terrestrial-water-use sample frame disclosed in Chinese utility model patent publication number CN221173905U. This portable, terrestrial-water-use sample frame has a wider range of applications and is more suitable for species surveys in different habitats and sample area settings, such as farmland, urban green spaces, and water areas. It has lower material and production costs, is lighter, and has a smaller storage volume, which helps reduce the burden of carrying it when going out. It is more convenient to use, and the installation and disassembly are simple, which can meet the needs of non-professionals.

[0004] However, this portable, land-based, and amphibious sample frame requires assembly of the entire device during use, which greatly reduces the device's efficiency and has certain limitations in practical use. Therefore, a foldable, retractable sample frame is proposed. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 A foldable and retractable template includes a sleeve 1, a folding adjustment structure 2 and an auxiliary structure 3 on the outside of the sleeve 1.

[0025] The folding adjustment structure 2 includes an adjustment rod 201. The adjustment rod 201 is disposed inside the sleeve 1. A first rotating shaft 202 is rotatably connected to the outer surface of the sleeve 1. A fixing structure 203 is disposed inside the adjustment rod 201. A hollow rotating sleeve 204 is disposed inside the adjustment rod 201. A second rotating shaft 205 is rotatably connected to the outer surface of the sleeve 1. A connecting piece 206 is fixedly installed on the outer surface of the second rotating shaft 205. A fixing screw 207 is threadedly connected inside the connecting piece 206. A handle 208 is fixedly installed on the front side of the fixing screw 207.

[0026] Furthermore, the auxiliary structure 3 includes a threaded sleeve 301, which is fixedly installed on the back of the sleeve 1. A support pin 302 is provided on the outside of the threaded sleeve 301. A first stud 303 is fixedly installed on the front of the support pin 302. A threaded hole 304 is provided on the back of the adjusting rod 201. A second stud 305 is threadedly connected inside the threaded hole 304. A hook 306 is fixedly installed on the back of the second stud 305.

[0027] Specifically, such as Figure 1 and Figure 3 As shown, when the device needs to be opened for use, the four sleeves 1 can be separated from each other and form a square structure by the setting of the first rotating shaft 202 and the hollow rotating sleeve 204. Then, the connecting piece 206 is rotated by the setting of the second rotating shaft 205 to drive the fixing screw 207 to rotate and adjust its position until the fixing screw 207 is aligned with the fixing screw hole of two of the sleeves 1. Then, the handle 208 is turned to drive the fixing screw 207 to move downward and connect with the fixing screw hole, thereby fixing the four sleeves 1 and ensuring the stability of the device in a square shape. Repeating the above operation can cancel the fixing and fold it for storage.

[0028] Specifically, such as Figure 1 As shown and Figure 3As shown, the sleeve 1, the first extension rod 2011, the second extension rod 2012, and the third extension rod 2013 are all 25 cm long, and their outer surfaces are painted with different colors. When the size of the device needs to be adjusted, the two opposing adjustment rods 201 are simultaneously driven to control the extension of the first extension rod 2011, the second extension rod 2012, and the third extension rod 2013 outwards, thereby fixing the size of the device. The adjusted length is fixed by the spring body 2032 and the spring bead 2033. The limiting block 2031 prevents the device from falling off when it moves beyond the internal range. When the first extension rod 2011, the second extension rod 2012, and the third extension rod 2013 are all inside the sleeve 1, the length of the device is 25 cm. Then, when the first extension rod 2011, the second extension rod 2012, and the third extension rod 2013 are extended outwards in sequence, they represent 50 cm, 75 cm, and 1 m, respectively. The different colors allow for a visual observation of the device length.

[0029] Specifically, such as Figure 2 and Figure 5 As shown, after the device length is adjusted, the support pin 302 can be connected to the two threaded sleeves 301 and the two hollow rotating sleeves 204 respectively through the first stud 303, and the device can be supported by the support pin 302. Then, according to the actual use requirements, the corresponding number of threaded holes 304 are opened on the back of the sleeve 1, the first extension rod 2011, the second extension rod 2012 and the third extension rod 2013. Then, the corresponding number of hooks 306 are prepared to cooperate with the second stud 305 to complete the installation. Then, the dividing line is connected to the corresponding hook 306.

[0030] In summary, this foldable and retractable template frame, through the setting of the folding adjustment structure 2, allows for the adjustment of the length of the four adjustment rods 201 according to actual usage needs. The adjustment length can be intuitively perceived through the sleeve 1 and the color of the adjustment rods 201. In conjunction with the setting of the auxiliary structure 3, the device can be fixed to the ground. A corresponding number of hooks 306 can be installed according to usage needs for installing the dividing rope. When the device is not in use, it can be retracted and folded as a whole for easy storage and carrying.
