Description

Technical Field

[0001] The utility model relates to the technical field of tobacco agricultural ground-inserting signs, and more specifically, to a portable tobacco agricultural test ground-inserting sign. Background Art

[0002] Tobacco is a plant of the genus Nicotiana in the family Solanaceae. It is an annual or limited perennial herb with a slightly woody base. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, gradually pointed at the apex, and gradually narrowed at the base until the stem becomes ear-shaped and semi-amplexicaul. Ground signs will be inserted in tobacco agricultural experimental sites as marks or records. The ground signs currently used in tobacco agricultural experimental sites are generally composed of a pole and a sign.

[0003] The current portable tobacco agricultural experiment ground-inserting sign, such as the "A Portable Tobacco Agricultural Experiment Ground-Inserting Sign" proposed in patent application number 202121870152.9, includes a ground-inserting sign frame, and the ground-inserting sign frame is provided with foot-operated components that are symmetrically distributed on the left and right, and the inside of the foot-operated component is provided with a reinforcing component that extends to the inside of the ground-inserting sign frame. For this portable tobacco agricultural experiment ground-inserting sign, the user can stand the ground-inserting sign frame on the soil, and then step on the foot-operated component with both feet, which makes it convenient for the user to insert the ground-inserting sign frame into the harder soil in turn. Before stepping on the foot-operated component with both feet, the reinforcing component can be adjusted to extend to the inside of the ground-inserting sign frame, thereby improving the stability of the foot-operated component during use. After use, the reinforcing component can be stored in the inside of the foot-operated component, and then the limit component is used to limit the stored reinforcing component, and finally the foot-operated component is stored in the inside of the ground-inserting sign frame. This ground-inserting sign has the advantages of being easy to insert into the harder soil and easy to carry.

[0004] In order to enhance the stability during installation, the existing portable tobacco agricultural experiment ground sign is used by providing a retractable foot pedal assembly. Although it can achieve the purpose of convenient stepping on the ground sign for installation, in actual use, the ground sign is composed of a sign and a pole. When the ground sign is carried, the sharp and protruding pole poses certain safety hazards and is prone to scratching the operator. The portability of the device cannot be further improved, which affects the use effect. Therefore, there is an urgent need to improve the technology of the structure of the portable tobacco agricultural experiment ground sign to improve this equipment. Utility Model Content

[0027] By pulling the latch 7, the first spring 9 is compressed and the latch 7 can be directly moved out of the fixed groove 5, so that the vertical rod 4 can be pushed into the inside of the telescopic groove 3. When the vertical rod 4 is against the limiting piece 10, the hollow limiting piece 10 is deformed by force. When the fixed groove 5 at the vertical rod 4 is aligned with the limiting piece 10, the limiting piece 10 restores its deformation and moves into the fixed groove 5, limiting the vertical rod 4 in the telescopic groove 3, thereby achieving the purpose of contracting the vertical rod 4, improving the convenience of carrying the sign 1, avoiding the vertical rod 4 with a sharp bottom end scratching or cutting the operator's hand when carrying the sign 1, improving the safety of use and facilitating use.

[0028] See also Figure 1 and Figure 3 Two symmetrical through holes 6 are provided in the connecting plate 2, and a latch 7 is slidably connected inside the through hole 6. A first spring groove 8 is provided on the outer side of the connecting plate 2 near the through hole 6, and a first spring 9 is fixedly connected between the inner wall of the first spring groove 8 and the outer wall of the latch 7. The first spring 9 is wound around the outside of the latch 7.

[0030] In the present invention, when the relevant technical personnel use the device, when it is necessary to carry the inserted sign, they can pull the latch 7, and the first spring 9 is compressed by force, so that the latch 7 can be directly moved out of the fixing slot 5, which is convenient for pushing the upright pole 4 into the telescopic slot 3. When the upright pole 4 is against the limiting piece 10, the hollow limiting piece 10 is deformed by force. When the fixing slot 5 at the upright pole 4 is aligned with the limiting piece 10, the limiting piece 10 restores the deformation and moves into the fixing slot 5, limiting the upright pole 4 in the telescopic slot 3, thereby achieving the purpose of contracting the upright pole 4, improving the convenience of carrying the sign 1, avoiding the upright pole 4 with a sharp bottom end from scratching or cutting the operator's hand when carrying the sign 1, and improving the safety of use;

[0031] When the plug-in plate is moved to a suitable position for plugging, the vertical pole 4 can be pulled out with force, and the length of the vertical pole 4 can be limited and fixed by the clamping mechanism. At this time, the rotating rod 22 is located at the part of the vertical pole 4 exposed to the outside of the soil.
