Technical Field

[0001] This utility model relates to the field of hazardous chemical testing, and more specifically, to a hazardous chemical safety testing device. Background Technology

[0002] Hazardous chemicals refer to chemicals with dangerous characteristics such as flammability, explosiveness, toxicity, toxicity, and corrosivity. They are widely used in industrial production. With the rapid development of my country's national economy, the demand for chemicals in various industries continues to increase. Chemicals, especially hazardous chemicals, are subject to inherent dangerous characteristics.

[0003] Traditional hazardous chemical testing often relies on manual methods, requiring operators to place samples one by one into the testing instrument. The testing process depends on manual operation of sample handling, positioning, and opening and closing of the cover. This results in low throughput and low efficiency, making it difficult to meet the needs of batch testing. Therefore, we propose a hazardous chemical safety testing device. Utility Model Content

[0004] The purpose of this invention is to solve the problem of low throughput and insufficient efficiency in current testing to meet the needs of batch testing.

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a hazardous chemical safety testing device, including a base. A rotating ring is rotatably connected to the upper surface of the base. A connecting rod is fixedly connected to the upper surface of the rotating ring. An installation ring is fixedly connected to the upper end of the connecting rod. A boss is fixedly connected to the upper surface of the base. A fixing cup is provided on the upper surface of the installation ring. A sliding rod is fixedly connected to the lower surface of the fixing cup. The lower end of the sliding rod slides through to the lower surface of the installation ring. A ball is provided at the lower end of the sliding rod, and the ball contacts the upper surface of the boss. A fixing ring is fixedly sleeved on the outer surface of the sliding rod located on the lower surface of the installation ring. A spring is fixedly connected to the upper surface of the fixing ring, and the upper end of the spring is fixedly connected to the lower surface of the installation ring. A positioning component is provided on the upper surface of the installation ring.

[0006] As a preferred technical solution of this application, the positioning component includes a vertical plate, which is fixedly connected to the upper surface of the mounting ring. A diagonal rod is rotatably connected to the vertical plate, and a through groove extending into the outer surface of the fixed cup is provided.

[0007] As a preferred technical solution of this application, the end of the inclined rod extends into the interior of the fixed cup through a through groove, and the end of the inclined rod is rotatably connected to a clamping plate.

[0008] As a preferred technical solution of this application, the inner side of the clamping plate is provided with a rubber pad, and the outer surface of the fixing cup is fixedly connected with a fixing plate.

[0009] As a preferred technical solution of this application, a vertical rod is fixedly connected to the fixing plate, and a connecting lug is rotatably sleeved on the outer surface of the vertical rod.

[0010] As a preferred technical solution of this application, a cover plate is fixedly connected to the connecting ear, and a limiting plate is fixedly connected to the upper end of the vertical rod.

[0011] As a preferred technical solution of this application, a torsion spring is fixedly connected to the lower surface of the limiting plate, and the lower end of the torsion spring is fixedly connected to the connecting ear.

[0012] As a preferred technical solution of this application, a lever is fixedly connected to the upper surface of the base, a mounting bracket is provided on the base, and a spectral detection head is provided on the mounting bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. Through the cooperation of structures such as the base, rotating ring, connecting rod, mounting ring, boss, fixed cup, sliding rod, ball bearing, fixed ring, and spring, multiple sample containers are installed in batches within the fixed cup. The intermittent rotation of the rotating ring aligns different fixed cups sequentially with the detection head. When the fixed cup rotates to the detection point, the ball bearing rolls along the upper surface of the boss, causing the fixed cup to rise automatically. At the same time, the spring is compressed to achieve buffer reset, thus completing the continuous switching and automatic positioning of multiple samples, significantly improving the throughput and automation level of hazardous chemical detection. 2. Through the coordination of structures such as the vertical plate, inclined rod, through groove, clamping plate, fixing plate, vertical rod, connecting ear, cover plate, limiting plate, torsion spring, lever, mounting bracket, and spectral detection head, automatic positioning and fixing is achieved as the fixed cup rises. The inclined rod changes from inclined to horizontal, driving the clamping plate to clamp the sample container inward. At the same time, the lever moves the connecting ear to automatically open the cover plate and compress the torsion spring. After the detection is completed, the fixed cup descends, the lever separates from the connecting ear, and the torsion spring resets to automatically close the cover plate. This effectively avoids sample leakage and the risk of manual operation, improving the safety and reliability of the detection. Attached Figure Description

[0020] Example 1 Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A hazardous chemical safety testing device includes a base 1. A rotating ring 2, which provides component installation and rotation functions, is rotatably connected to the upper surface of the base 1. A connecting rod 3 for connection is fixedly connected to the upper surface of the rotating ring 2. An installation ring 4 is fixedly connected to the upper end of the connecting rod 3.

A sliding rod 7, which provides a sliding function, is fixedly connected to the lower surface of the fixed cup 6. The lower end of the sliding rod 7 slides through to the lower surface of the installation ring 4. A ball bearing 8 for reducing friction is provided at the lower end of the sliding rod 7. The ball bearing 8 contacts the upper surface of the boss 5. A fixed ring 9 is fixedly sleeved on the outer surface of the lower surface of the installation ring 4. A spring 10 is fixedly connected to the upper surface of the fixed ring 9. The upper end of the spring 10 is fixedly connected to the lower surface of the installation ring 4. A positioning component is provided on the upper surface of the installation ring 4.

[0021] Through the cooperation of structures such as base 1, rotating ring 2, connecting rod 3, mounting ring 4, boss 5, fixed cup 6, sliding rod 7, ball bearing 8, fixed ring 9, and spring 10, multiple sample containers are installed in batches within the fixed cup 6. The intermittent rotation of the rotating ring 2 allows different fixed cups 6 to align sequentially with the detection head. When the fixed cup 6 rotates to the detection point, the ball bearing 8 rolls along the upper surface of the boss 5, causing the fixed cup 6 to rise automatically. At the same time, the spring 10 is compressed to achieve buffer reset, thus completing the continuous switching and automatic positioning of multiple samples, significantly improving the throughput and automation level of hazardous chemical detection.

[0022] Example 2 The hazardous chemical safety testing equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the positioning assembly includes a vertical plate 11, which is fixedly connected to the upper surface of the mounting ring 4. A diagonal rod 12 is rotatably connected to the vertical plate 11. A through groove 13 extending into the outer surface of the fixing cup 6 is provided. The end of the diagonal rod 12 extends into the interior of the fixing cup 6 through the through groove 13. A clamping plate 14 for fixing is rotatably connected to the end of the diagonal rod 12. A rubber pad is provided on the inner side of the clamping plate 14. A fixing plate 15 is fixedly connected to the outer surface of the fixing cup 6. A [missing information - likely a component or part] is fixedly connected to the fixing plate 15. A vertical rod 16 has a connecting ear 17 rotatably fitted on its outer surface. A cover plate 18 for sealing the sample container is fixedly connected to the connecting ear 17. A limiting plate 19 is fixedly connected to the upper end of the vertical rod 16. A torsion spring 20 for providing reset elasticity is fixedly connected to the lower surface of the limiting plate 19. The lower end of the torsion spring 20 is fixedly connected to the connecting ear 17. A lever 21 is fixedly connected to the upper surface of the base 1. A mounting bracket 22 is provided on the base 1. A spectral detection head 23 is provided on the mounting bracket 22.

[0023] Through the coordination of structures such as vertical plate 11, inclined rod 12, through groove 13, clamping plate 14, fixing plate 15, vertical rod 16, connecting ear 17, cover plate 18, limiting plate 19, torsion spring 20, lever 21, mounting bracket 22, and spectral detection head 23, the system achieves automatic positioning and fixing by having the inclined rod 12 move from tilt to horizontal during the upward movement of the fixed cup 6, causing the clamping plate 14 to clamp the sample container inward. At the same time, the lever 21 moves the connecting ear 17 to automatically open the cover plate 18 and compress the torsion spring 20. After the detection is completed, the fixed cup 6 descends, the lever 21 separates from the connecting ear 17, and the torsion spring 20 resets to automatically close the cover plate 18. This effectively avoids sample leakage and the risk of manual operation, and improves the safety and reliability of the detection.

[0024] The base 1 also needs to be equipped with a drive component to drive the rotating ring 2 to rotate, preferably a stepper motor for precise control.

[0025] The usage process of the hazardous chemical safety testing equipment provided by this utility model is as follows: When testing hazardous chemicals, multiple sample containers are first placed inside the fixed cup 6. Then, an external drive rotates the rotating ring 2. Each 90-degree rotation of the rotating ring 2 aligns one of the fixed cups 6 with the spectroscopic detection head 23. When the fixed cup 6 is aligned with the spectroscopic detection head 23, its lower ball bearing 8 moves to the upper surface of the boss 5, contacting the boss 5 and causing the fixed cup 6 to rise. As the sliding rod 7 rises, it compresses the spring 10. Subsequently, the spring 10 ensures that the ball bearing 8 remains in contact with the base 1. During the rise of the fixed cup 6, the spring 10 compresses the ball bearing 8. Since the height of the vertical plate 11 is fixed and the inclined rod 12 is inclined downward, when the fixed cup 6 rises, it will drive the inclined rod 12 to tend to be horizontal, thereby reducing the distance between the two opposite inclined rods 12, which in turn drives the two clamping plates 14 to fix the sample container. At the same time, when the fixed cup 6 is aligned with the spectral detection head 23, it will first contact the lever 21. The lever 21 is used to open the cover plate 18 and compress the torsion spring 20. After the detection is completed and the movement continues, the lever 21 separates from the connecting ear 17 and automatically resets under the action of the torsion spring 20 to avoid sample leakage.
