Description

Technical Field

[0001] This utility model relates to the technical field of geological exploration, and in particular to a depth sounding rod for geological exploration. Background Technology

[0002] Traditional sounding rods commonly used in geological exploration suffer from drawbacks in portability. They are often fixed-length single-rod structures or multi-segment rods requiring threaded connections. Fixed rods are typically long and space-consuming, and parts may be lost after disassembly. Their suitability for carrying in field hiking scenarios needs improvement. Regarding connection stability, spliced ​​sounding rods often rely on threaded or snap-fit ​​connections, which may develop gaps after repeated use. This can cause the rod to wobble during sounding, potentially leading to measurement data inaccuracies. Furthermore, some folding rods with hinged structures, if lacking a locking function, may bend on their own when upright, failing to withstand the downward pressure required for sounding. In addition, traditional sounding rods mostly only provide basic sounding functions, often lacking designs related to auxiliary positioning and convenient reading. When used in complex terrains such as slopes and soft soil, additional tools are usually required for fixation, reducing operational efficiency. Therefore, it is necessary to design a geological exploration sounding rod that is easy to carry when folded, has good stability when upright, and is more convenient to operate, to address the aforementioned problems in use. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a depth sounding rod for geological exploration.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A sounding rod for geological exploration includes a first rod body, a second rod body, and a third rod body. The first rod body is rotatably connected to the second rod body, and the second rod body is rotatably connected to the third rod body. A first sleeve is fixedly connected to the bottom of the first rod body and one end and the other end of the top of the second rod body. Bolts are movably passed through both first sleeves, and one end of each bolt is threaded to the corresponding first sleeve. A second sleeve is fixedly connected to the bottom of the second rod body and the top of the third rod body.

[0005] Preferably, one end of the first rod and one end of the third rod are fixedly connected to both ends of the second rod, and the plurality of magnets are magnetically attracted to each other by their respective magnets.

[0006] Preferably, a handle is fixedly connected to one end of the first rod.

[0007] Preferably, the third rod is fixedly connected to a detection sensing component.

[0008] Preferably, the spacing between the two first sets of bodies at the first rod and the second rod is adapted to the corresponding second sets of bodies.

[0009] Preferably, the two bolts are respectively adapted to the corresponding second sleeve insertion end.

[0010] Preferably, one end of the first rod is in contact with the second rod, and one end of the second rod is in contact with the third rod.

[0011] The beneficial effects of this utility model are as follows: 1. By coordinating the first, second, and third rods, the first and second sleeves, and the bolts, the first, second, and third rods are rotated until they are aligned axially. After placement, the bolts corresponding to the first sleeves are movably threaded through the corresponding second sleeves and connected to the other corresponding first sleeves via threads. This completes the assembly. On one hand, the rotatable and foldable three-rod structure eliminates the need to disassemble the rods into individual parts, reducing the possibility of losing parts in traditional spliced ​​rods. The overall size is also smaller after folding, making it easier to carry for hiking in the wild compared to fixed-length rods, thus improving portability. On the other hand, the bolts... The assembly method, where the bolt passes through the first and second sets of bodies and is connected by threads, offers greater stability than traditional threaded or snap-fit ​​connections. Even after multiple uses, it reduces gaps, thereby decreasing the probability of rod swaying during depth measurement and reducing measurement data deviation. It also better withstands the downward pressure required for depth measurement, avoiding the problem of self-bending when erected, similar to some folding rods that lack locking functions. Furthermore, this assembly method is relatively simple to operate, requiring no additional complex tools. Combined with its foldable nature, it indirectly reduces operational steps when used in complex terrains such as slopes and soft soil in the field, helping to improve overall operational efficiency and further compensating for the shortcomings of traditional depth measurement rods, such as limited functionality and inconvenient operation. 2. By coordinating the first, second, and third rods with a magnet, the first, second, and third rods are secured by magnetic attraction through their built-in magnets after folding. This offers several practical advantages: This securing method eliminates the need for additional clips, bolts, or other loose fasteners, avoiding the problem of easily lost parts associated with traditional folding poles and simplifying the folding process; the magnetic attraction keeps the three rods tightly parallel and in place, preventing them from coming apart or colliding during transport, reducing wear and tear, and making the overall structure more organized and easier to pack into a backpack or carry by hand; furthermore, the magnetic closure process is simple and effortless, allowing for easy separation and unfolding of the rods with one hand during field surveys, further enhancing operational convenience and meeting the rapid operational needs of complex field environments.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1, referring to Figures 1 to 5 A sounding rod for geological exploration includes a first rod body 1, a second rod body 2, and a third rod body 3. The first rod body 1 is rotatably connected to the second rod body 2, and the second rod body 2 is rotatably connected to the third rod body 3, allowing the three rod bodies to be flexibly switched to a coaxial unfolded or parallel folded state to adapt to different usage and carrying scenarios. The bottom of the first rod body 1 and one and the other ends of the top of the second rod body 2 are both fixedly connected to a first sleeve body 4. Bolts 5 are movably inserted through both first sleeve bodies 4, with one end of each bolt 5 threadedly connected to the corresponding first sleeve body 4. Each first sleeve body 4 has a pre-drilled hole for the bolt 5 to movably pass through. Two bolts 5 pass through from one side of the corresponding first sleeve 4, and one end of the bolt 5 can be threaded to the corresponding first sleeve 4 on the other side. The threaded engagement achieves a tight lock after the rods are joined, preventing loosening during use. The bottom of the second rod 2 and the top of the third rod 3 are both fixedly connected to the second sleeve 6, which is used to cooperate with the first sleeve 4 to achieve the joining. The structure of the second sleeve 6 matches the first sleeve 4. When the rod is unfolded, it can be embedded between the two first sleeves 4 of the adjacent rod to form a docking and positioning, providing a stable foundation for the subsequent locking of the bolts 5.

[0016] In this embodiment, magnets 7 are fixedly connected to one end of the first rod 1 and the third rod 3, and to both ends of the second rod 2. The magnetic polarities of the magnets 7 are matched. When the three rods are folded to a parallel state, the magnets 7 at corresponding positions can attract each other, thereby temporarily fixing the folded rods and preventing them from coming apart due to shaking during carrying. Multiple magnets 7 attract each other to their corresponding magnets 7. A handle 9 is fixedly connected to one end of the first rod 1, making it convenient for the operator to push the detection sensor component 8 downward to contact the ground. The detection sensor component 8 is fixedly connected to the third rod 3. The spacing between the two first sets 4 at the first rod 1 and the second rod 2 is adapted to the corresponding second sets 6, that is, the second sets 6 can be precisely embedded into the two first sets 4 of the adjacent rod. There are no obvious gaps between them, thus avoiding lateral offset or wobbling after the rods are joined, ensuring the overall straightness of the sounding rod. The two bolts 5 are respectively adapted to the insertion end of the corresponding second sleeve 6. That is, when the bolt 5 passes through the second sleeve 6, it can fit tightly with the hole of the second sleeve 6 without any loose space. This ensures that after the bolt 5 is tightened, the second sleeve 6 can be firmly fixed between the two first sleeves 4, further improving the stability of the rod connection and avoiding loosening of the connection due to the gap between the bolt 5 and the second sleeve 6 during the sounding process. One end of the first rod 1 contacts the second rod 2, and one end of the second rod 2 contacts the third rod 3, reducing the overall volume after folding. At the same time, it avoids folding jamming due to uneven contact parts, improving the smoothness of the folding operation.

[0017] The working principle of this embodiment is as follows: In use, first rotate the first rod 1, the second rod 2, and the third rod 3 to the same axis, then move the bolt 5 corresponding to the first sleeve 4 through the corresponding second sleeve 6 and thread it to another corresponding first sleeve 4 to complete the assembly of the depth sounding rod. With this assembly method, the three rods can be rotated and folded without disassembling individual parts, which can reduce the loss of parts in traditional splicing rods. After folding, the size is small and more convenient to carry when hiking in the field. Moreover, the bolt 5 connection is more stable than the traditional thread or snap-fit ​​connection, and the gap can be reduced even after multiple uses. This design reduces the probability of pole swaying and measurement data deviation, better withstands the pressure of depth measurement, and prevents self-bending when erected. Operation also requires no complicated tools, reducing steps and improving efficiency in complex field terrain. After the depth measurement operation is completed, the first, second, and third poles are rotated until they are in parallel contact with each other. They are then folded and fixed by the magnetic attraction of the poles' built-in magnets. This fixing method eliminates the need for additional loose fasteners, preventing parts loss, simplifying operation, and ensuring that the three poles fit tightly without swaying, reducing wear. Opening and closing is effortless, and they can be separated and unfolded with one hand, meeting the needs of rapid field operations.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
