Description

Technical Field

[0001] This utility model relates to the field of water quality testing instruments, and in particular to a portable water quality testing instrument. Background Technology

[0002] Portable water quality analyzers are indispensable tools in many fields such as modern environmental monitoring, aquaculture, and field water source exploration. Their compact size, portability, and ease of operation break the dependence of traditional water quality testing on fixed laboratory environments. Users can easily carry them to various water sources to obtain water quality data anytime, anywhere. Whether it's streams and lakes in remote mountainous areas, landscape water in urban parks, or aquaculture ponds, they can quickly determine key indicators such as pH, dissolved oxygen, and pollutant content. This improves the timeliness and coverage of water quality testing, providing strong support for water resource protection, rational utilization, and the healthy development of related industries.

[0003] A portable water quality analyzer is disclosed in publication number CN202223025449.2, comprising an analyzer body with a protective structure at the edge of the outer wall of the body, an insertion port at one end of the top of the body, and a storage structure at the other end. The advantage of this invention is that the storage structure allows for the storage of the line and the test rod. However, while the application does store the test rod, it does not consider the stability of the storage. When the analyzer is shaken during transport, such as when walking on rugged mountain roads, or is accidentally impacted, such as when placed in a backpack with other equipment, the test rod can easily detach from the device. This not only damages the test rod and increases maintenance costs but also affects the timeliness and accuracy of on-site testing. Therefore, this portable water quality analyzer is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable water quality tester, which aims to improve the problem that the test rod is easily detached from the surface of the device due to shaking or impact during placement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable water quality tester includes a tester, with connecting columns fixedly connected to both sides of the top of the tester, a connecting tube fixedly connected inside each connecting column, a test rod fixedly connected to one end of each connecting tube, a fixing component provided on the outer wall of the test rod, and a protective component provided at one end of the test rod.

[0028] 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.

[0029] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a portable water quality tester, comprising a tester 1, with connecting columns 2 fixedly connected to both sides of the top of the tester 1, a connecting tube 3 fixedly connected inside each connecting column 2, a test rod 4 fixedly connected to one end of each connecting tube 3, a fixing component provided on the outer wall of the test rod 4, and a protective component provided at one end of the test rod 4.

[0030] The fixing assembly includes multiple arc-shaped clamps 9, which are located on the outer wall of the detection rod 4. The arc-shaped clamps 9 tightly hold the detection rod 4, providing stable support and protection. Fixing blocks 1-5 are fixedly connected to both sides of the detector 1. Fixing blocks 1-5 act as a bridge connecting the main body of the detector 1 to subsequent components. They provide reliable mounting points for the arc-shaped connecting plate 6, allowing the arc-shaped connecting plate 6 to be firmly attached to the detector 1. An arc-shaped connecting plate 6 is fixedly connected to the inner wall of each fixing block 1-5, and fixing blocks 2-7 are fixedly connected to both sides of each arc-shaped connecting plate 6. Fixing blocks 2-7 enhance the structural stability of the arc-shaped connecting plate 6. The adjacent fixing blocks 7 work together to provide a stable installation base for the connecting shaft 8. The connecting shaft 8 is fixedly connected between the two adjacent fixing blocks 7. The outer wall of each connecting shaft 8 is rotatably connected to the inside of each side arc-shaped clamp 9. The connecting shaft 8 serves as the rotation axis of the arc-shaped clamp 9, allowing the arc-shaped clamp 9 to rotate flexibly relative to the arc-shaped connecting plate 6. Each side of the arc-shaped connecting plate 6 is provided with multiple springs 10. One end of the spring 10 is fixedly connected to the outer wall of the arc-shaped clamp 9, and the other end of the spring 10 is fixedly connected to the inner wall of the arc-shaped connecting plate 6.

[0031] Specifically, during the fixing process of the detection rod 4, the detection rod 4 is first moved between the two arc-shaped clamps 9. At this time, the outer wall of the detection rod 4 contacts the inner wall of the two arc-shaped clamps 9. Through the squeezing force of the outer wall, the two arc-shaped clamps 9 are caused to rotate in opposite directions around the connecting shaft 8. This reverse rotation not only changes the structure of the arc-shaped clamps 9, but also pushes the spring-10 to compress, thereby providing the necessary support force for the subsequent fixing operation. When the outer wall of the detection rod 4 continues to move to the inner wall of the two arc-shaped clamps 9, the arc-shaped clamps 9 are affected by the compressive force of the spring-10 and begin to store elastic potential energy. When the detection rod 4 is at its maximum... When the target position is reached, spring 10 releases a reverse restoring force, pushing the arc-shaped clamp 9 to continuously compress the detection rod 4. At this time, the arc-shaped clamp 9 tightly covers the outer wall of the detection rod 4, ensuring that the arc-shaped clamp 9 exerts a uniform and sufficient compressive force on the detection rod 4. This design ensures that the detection rod 4 remains stable and secure under the action of the arc-shaped clamps 9 on both sides throughout the entire fixing process. Due to the elastic characteristics of spring 10, the arc-shaped clamp 9 can automatically adjust according to the shape and size of the detection rod 4, always providing appropriate clamping force, avoiding loosening or positional displacement during the fixing process, and improving the stability of the detection rod 4.

[0032] Reference Figure 1 and Figure 3The protective assembly includes multiple rubber protective heads 12, each located at the bottom of the detection rod 4. The function of the rubber protective heads 12 is to protect the detection rod 4 from external impacts or contamination, reduce mechanical wear, and prevent performance degradation due to environmental factors. Simultaneously, the rubber material has good elasticity, effectively absorbing vibration and impact, extending the equipment's service life. Each detection rod 4 has a connecting ring 11 fixedly connected to its outer wall, and multiple connecting shells 13 are fixedly connected to the top of each rubber protective head 12. The connecting shells 13 securely connect the rubber protective head 12 to other components, ensuring stable operation of the protective head, and provide appropriate structural support through limiting posts 14 to prevent displacement or loosening of the components. Each connecting shell 13 has a limiting post 14 fixedly connected to its inner wall, and each limiting post 14 has two springs 16 at both ends. Each spring 16 has a slip ring 15 fixedly connected to one end. The other end of each spring 16 is fixedly connected to the inner wall of the connecting shell 13. The slip ring 15 is slidably connected to the outer wall of the limiting post 14. Each slip ring 15 is rotatably connected to a transmission plate 17 on one side. The transmission plate 17 is rotatably connected to one side of the locking block 18. The locking block 18 is engaged with the connecting ring 11. The connection between the slip ring 15 and the transmission plate 17 enables the slip ring 15 to effectively transmit force to the transmission plate 17, thereby controlling the movement of the locking block 18. The function of the transmission plate 17 is to convert the rotational force from the slip ring 15 into the movement of the locking block 18, thereby realizing the linkage of different components in the device. The engaging action between the locking block 18 and the connecting ring 11 ensures the stability of the rubber protective head 12.

[0033] Specifically, during the process of protecting the detection rod 4, the rubber protective head 12 is first moved to the bottom of the connecting ring 11, and the connecting shell 13 is inserted into the hole inside the connecting ring 11, ensuring a stable connection between the connecting shell 13 and the connecting ring 11. During this process, the inner wall of the connecting ring 11 applies a squeezing force to the locking block 18, causing the locking block 18 to move into the connecting shell 13. The transmission plates 17 on both sides push the slip ring 15 to slide along the outer wall of the limiting post 14. At this time, the slip ring 15 slides to the opposite side, causing the second spring 16 to be compressed and storing elastic potential energy. As the slip ring 15 moves further, the second spring 16 is compressed to a certain extent, thereby stimulating its rebound force. When the locking block 18 reaches... When the spring reaches the specific slot inside the connecting ring 11, the rebound force of the second spring 16 immediately acts on the locking block 18, pushing it into the slot and fixing it in place. The locking block 18 firmly locks the slot inside the connecting ring 11, achieving precise fixation of the rubber protective head 12 and effectively preventing it from moving during operation. The fixation of the rubber protective head 12 allows it to tightly cover one end of the detection rod 4, providing important protection for the detection rod 4 and effectively preventing one end of the detection rod 4 from being impacted or collided during use. This avoids a decrease in detection accuracy or equipment damage caused by collisions, enhances the equipment's protection of the detection rod 4, and effectively improves the long-term service life and detection effect of the equipment.

[0034] Working principle: During the fixing of the detection rod 4, the detection rod 4 is moved between the two arc-shaped clamps 9. The outer wall of the detection rod 4 presses against the arc-shaped clamps 9, causing the two arc-shaped clamps 9 to rotate in opposite directions around the connecting shaft 8, and pushing the spring 10 to compress. When the outer wall of the detection rod 4 moves to the inner wall of the two arc-shaped clamps 9, the rebound force of the spring 10 pushes the arc-shaped clamps 9 to press against the detection rod 4, and the arc-shaped clamps 9 maintain sufficient pressure on the outer wall of the detection rod 4 at all times, enhancing the stability of the detection rod 4 during placement. During the protection of the detection rod 4, the rubber protective head 12 is moved to the bottom of the connecting ring 11. The connecting shell 13 is inserted into the hole inside the connecting ring 11. The inner wall of the connecting ring 11 presses the locking block 18 into the connecting shell 13. The sliding ring 15 is pushed to slide on the outer wall of the limiting post 14 to the opposite side by the transmission plates 17 on both sides, so that the second spring 16 is compressed. When the locking block 18 moves to a specific slot inside the connecting ring 11, the rebound force of the second spring 16 pushes the locking block 18 to lock and fix the slot inside the connecting ring 11, thereby fixing the position of the rubber protective head 12. The rubber protective head 12 protects one end of the detection rod 4, preventing the detection rod 4 from colliding and affecting the detection effect, thus enhancing the protection of the detection rod 4 by the equipment.
