Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and in particular to a multifunctional soil pH and humidity measuring instrument. Background Technology

[0002] Measuring soil pH and moisture can provide a good understanding of the current soil condition, enabling the development of a scientific plan that is both reasonable and effective. This facilitates management, fertilization, and other operations. The measurement method usually involves inserting the measuring tip directly into the soil and then waiting for the measurement to be completed. The actual performance of existing measuring instruments is generally mediocre. First, the measuring end is directly exposed, making it prone to bumps or scratches during carrying and storage, thus reducing its service life. Second, in use, the measuring end is usually simply inserted into the soil for measurement, resulting in relatively poor stability. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as susceptibility to bumps or scratches that reduce service life, by proposing a multifunctional soil pH and humidity measuring instrument.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multifunctional soil pH and humidity measuring instrument includes a main body and a measuring end located at the bottom of the main body; Two protective shells are used to support the main body of the measuring instrument and protect the measuring ends. The two protective shells are respectively fitted over the outside of the two measuring ends. Two connecting strips are used to connect the measuring instrument body and the protective shell. A first connecting seat is fixedly installed on both sides of the measuring instrument body, and a second connecting seat is fixedly installed on one side of the protective shell. The two ends of the connecting strips are rotatably connected to the first and second connecting seats on the same side, respectively. A locking mechanism is provided inside the connecting strips to fix the rotation point of the connecting strips.

[0005] In one possible design, the locking mechanism includes two locking plates. A sliding cavity is formed inside the connecting strip, and a sliding plate is slidably disposed inside the sliding cavity, with one end of the sliding plate extending through to the outside of the connecting strip. The two locking plates are respectively fixed at both ends of one side of the sliding plate, and both locking plates slide through to the outside of the connecting strip. A first locking slot and a second locking slot are respectively formed on the side of the first connecting seat, and both the first and second locking slots cooperate with adjacent locking plates. A third locking slot and a fourth locking slot are respectively formed on the side of the second connecting seat, and both the third and fourth locking slots cooperate with adjacent locking plates.

[0006] In one possible design, a plurality of limiting rods are fixedly provided on one side of the inner wall of the sliding cavity, the sliding plate is slidably sleeved on the outer wall of the limiting rods, and a compression spring is sleeved on the outer wall of the limiting rods, with the two ends of the compression spring being fixedly provided on one side of the sliding plate and one side of the inner wall of the sliding cavity, respectively.

[0007] In one possible design, the outer wall of the measuring end is fitted with a ring.

[0008] In one possible design, a rubber ring is fixedly provided on the inner wall of the ring, and the inner wall of the rubber ring is in contact with the outer wall of the measuring end.

[0009] In one possible design, the two protective shells are fitted together.

[0010] In this application, during actual use, pressing the sliding plate will cause the two locking plates to move, disengaging them from slots two and four. This releases the fixing between the measuring instrument body, the protective shell, and the connecting strip. The protective shell can then be rotated open and adjusted to... Figure 1 In this state, the slide will be reset by the compression spring, so that the two plates are inserted into the first and third slots respectively, and the protective shell is fixed again. Then, the measuring end of the measuring instrument is inserted into the ground to take a measurement. The end of the protective shell will be supported on the ground to increase stability.

[0011] In this utility model, the multifunctional soil pH and humidity measuring instrument can be protected by a protective shell, which can cover the measuring end during daily storage or carrying, and can be opened during use to support the ground, thereby increasing the stability during measurement. In this utility model, the multifunctional soil pH and humidity measuring instrument can be fixed in different positions through a locking mechanism, thereby enabling the measuring instrument to be adjusted to different states for use according to different situations. In this invention, the protective shell can be rotated open to serve as a support point, thereby ensuring stability during measurement. After use, it can be reset to protect the measuring end, making it convenient to carry and store. Attached Figure Description

[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. Example 1:

[0015] Reference Figure 1-2 A measuring instrument includes: a main body 1 and a measuring end 2 located at the bottom of the main body 1. The main body 1 is the core control and display part of the entire measuring instrument, used to process measurement data and display measurement results. The measuring end 2 is directly inserted into and in contact with the soil to obtain soil pH and moisture information; its model is LY101 soil tester.

[0016] At the bottom of the measuring instrument body 1, two protective shells 5 are respectively fitted over the two measuring ends 2 to support the measuring instrument body 1 and protect the measuring ends 2. The protective shells 5 can effectively prevent the measuring ends 2 from being damaged by external impacts, scratches, etc. when not in use, and can also provide stable support when the measuring instrument is placed.

[0017] Reference Figure 3-4 A first connecting seat 6 is fixedly installed on both sides of the measuring instrument body 1, and a second connecting seat 10 is fixedly installed on one side of the protective shell 5. Two connecting strips 4 connect the measuring instrument body 1 and the protective shell 5 respectively, with the two ends of the connecting strips 4 rotatably connected to the first connecting seat 6 and the second connecting seat 10 on the same side. By using the connecting strips 4 as connection points, the protective shell 5 can rotate relative to the measuring instrument body 1, thereby realizing the opening and closing operation of the measuring end 2.

[0018] The connecting strip 4 has an internal locking mechanism for fixing its rotation point. Specifically, the locking mechanism includes two locking plates 13. A sliding cavity 14 is formed inside the connecting strip 4, and a sliding plate 9 is slidably disposed inside the sliding cavity 14, with one end of the sliding plate 9 extending through to the outside of the connecting strip 4. The two locking plates 13 are fixedly disposed at both ends of one side of the sliding plate 9, and both locking plates 13 extend through to the outside of the connecting strip 4. A first locking slot 7 and a second locking slot 8 are respectively formed on the side of the first connecting seat 6, both of which cooperate with adjacent locking plates 13. A third locking slot 11 and a fourth locking slot 12 are respectively formed on the side of the second connecting seat 10, both of which cooperate with adjacent locking plates 13.

[0019] To ensure the stability of the sliding plate 9, multiple limiting rods 15 are fixedly installed on one inner wall of the sliding cavity 14, and the sliding plate 9 is slidably sleeved on the outer wall of the limiting rods 15. Simultaneously, a compression spring 16 is sleeved on the outer wall of the limiting rods 15, and the two ends of the compression spring 16 are respectively fixed to one side of the sliding plate 9 and one inner wall of the sliding cavity 14. The presence of the compression spring 16 allows the sliding plate 9 to automatically reset when not pushed by external force, maintaining a tight fit between the locking plate 13 and the locking slot, and preventing accidental displacement of the protective shell 5.

[0020] In practical use, pressing the sliding plate 9 will cause the two locking plates 13 to move, disengaging them from the inside of the second locking slot 8 and the fourth locking slot 12. This will release the fixing between the measuring instrument body 1, the protective shell 5, and the connecting strip 4. Then, the protective shell 5 can be rotated open to adjust it to... Figure 1 In this state, the slide plate 9 will be reset by the compression spring 16, allowing the two locking plates 13 to be inserted into the first locking slot 7 and the third locking slot 11 respectively, thus re-fixing the protective shell 5. After that, the measuring end 2 of the measuring instrument can be inserted into the ground for measurement. The end of the protective shell 5 will be supported on the ground to increase stability. The protective shell 5 can be designed as an arc-shaped shell, a polygonal shell, or a streamlined shell. The arc-shaped shell (radius 50-80mm) can effectively disperse external impact, the polygonal shell (quadrilateral, hexagonal, or octagonal) is easy to manufacture, and the streamlined shell can reduce the risk of snagging during carrying. The connecting strip 4 can be set as a rectangular strip, a trapezoidal reinforcing strip, or a wavy strip. The wavy strip can provide better bending resistance, and the trapezoidal strip can enhance the stress distribution at the connection point.

[0021] The wire diameter of the compression spring 16 ranges from 0.5 to 2 mm, the outer diameter from 5 to 15 mm, the free length from 20 to 50 mm, and the elastic coefficient from 10 to 50 N / mm. Stainless steel springs are preferred. The specific parameters are selected according to the opening and closing force requirements of the protective shell: when the measuring end length is >150 mm, a spring with a wire diameter of 1.2 mm and an elastic coefficient of 30 N / mm is used; for conventional sizes, a spring with a wire diameter of 0.8 mm and an elastic coefficient of 20 N / mm is used.

[0022] This application can be used in the field of soil testing, or in other fields applicable to this application. Example 2:

[0023] refer to Figure 1 An improvement upon Embodiment 1: A multifunctional soil pH and moisture measuring instrument, applied in the field of soil testing, features a ring 3 fitted onto the outer wall of the measuring end 2. A rubber ring is fixedly mounted on the inner wall of the ring 3, with the inner wall of the rubber ring fitting snugly against the outer wall of the measuring end 2. After use, the ring 3 can be directly removed from the upper part of the outer wall, allowing the rubber ring on its inner wall to wipe away any remaining soil from the outer wall of the measuring end 2, facilitating cleaning.

[0024] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
