Description

Technical Field

[0001] This utility model belongs to the field of detection and sampling technology, specifically relating to a sampling tube for detecting hazardous chemicals. Background Technology

[0002] Sampling and testing chemicals allows for timely understanding of product quality, providing a basis for quality control. It also helps identify potential hazards, preventing production accidents, and assessing the environmental impact of chemicals, providing data support for environmental protection measures. Appropriate sampling equipment should be selected based on the nature of the chemicals; for volatile, flammable, and explosive chemicals, closed samplers should be used; for highly corrosive chemicals, corrosion-resistant samplers should be used. During sampling, it is crucial to prevent contamination or damage from external factors and to adhere to regulations: strictly follow laboratory safety regulations and chemical sampling management regulations to ensure a safe and controllable sampling process. Timely analysis is essential; samples should be analyzed and tested promptly after sampling to prevent deterioration or ineffectiveness due to prolonged storage. Currently, sampling tubes require test tube racks for placement, resulting in insufficient stability and poor self-protection and impact resistance during sampling. Therefore, the inventor proposes a sampling tube for hazardous chemical testing. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] This specific embodiment is a sampling tube for detecting hazardous chemicals, and its structural schematic diagram is shown below. Figure 1As shown, the device includes a sampling tube 7, a support base 4, a protective rod 6, and a suction assembly 2. The two ends of the sampling tube 7 are respectively fixed with support bases 4. The support bases 4 are symmetrically distributed at intervals, and the protective rods 6 are vertically installed between them. The protective rods 6 surround the outer periphery of the sampling tube 7. The support base 4 located at the bottom has support feet 5 on its outer wall, and the support feet 5 are distributed around the outer periphery of the support base 4.

[0024] Reference Figure 2 The suction assembly 2 includes a piston head 9, a drive rod 10, a collar 14, and a slip ring 12. The collar 14 is sleeved on the outside of the sampling tube 7. The slip ring 12 is fixedly connected to the collar 14. The collar 14 is sleeved on the outside of the protective rod 6. The drive rod 10 is located in the center of the inner side of the collar 14. The drive rod 10 is vertically arranged, and the top end is fixedly connected to the piston head 9, which slides vertically along the inside of the sampling tube 7.

[0025] Reference Figure 3 The sampling tube 7 has an aspiration head 1 at one end, which is connected to the sample storage chamber 18. A sealing cap 15 is provided on the aspiration head 1. A lifting groove 16 is provided on the outer wall of the sampling tube 7 corresponding to the movable chamber 17. A connecting slider 11 slides through the lifting groove 16, and both ends of the connecting slider 11 are fixedly connected to the drive rod 10 and the collar 14, respectively. The slip ring 12 is a hollow structure, and a locking hole 13 is provided through its outer wall. A protective rod 6, which is slidably connected to the slip ring 12, is provided with a spring buckle 3, which is fitted and engaged with the locking hole 13.

[0026] Reference Figure 4 A horizontally fixed partition block 8 is installed inside the sampling tube 7, which divides the inside of the sampling tube 7 into a sample storage chamber 18 and a movable chamber 17. The piston head 9 slides along the sample storage chamber 18. The partition block 8 has an opening at its center, through which the drive rod 10 slides.

[0027] Working principle: In use, first open the sealing cap 15, leaving the suction head 1 open. Then, insert the suction head 1 into the sampled chemical. Pull the slip ring 12, which slides along the outer wall of the protective rod 6 towards the spring buckle 3. The slip ring 12 drives the collar 14 to slide, which slides along the outer wall of the sampling tube 7. Simultaneously, the connecting slider 11 drives the drive rod 10 to move synchronously. The piston head 9 connected to the end of the drive rod 10 adsorbs the chemical sample from the suction head 1 towards the sample storage chamber 18 inside the sampling tube 7. This working principle is consistent with that of syringes in the prior art. As the piston head 9 moves continuously... As the sample is moved, the sample storage chamber 18 is gradually filled with chemical samples until the slip ring 12 slides to the position of the spring buckle 3. When the spring buckle 3 is flush with the locking hole 13, it automatically pops out and the slip ring 12 is fixed and locked to the outside of the protective rod 6. At this time, the piston head 9 is also fixed in the sampling tube 7, which can effectively prevent the leakage of the sampled chemicals and improve the stability of chemical storage. After sampling, the sealing cover 15 is closed. The sampling tube 7 can be vertically fixed by the setting of the support foot 5 to prevent it from tipping over. In addition, the setting of the protective rod 6 can protect against the impact force in the first time when subjected to external impact. It is highly practical, safe, and can be widely promoted.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
