Description

Technical Field

[0001] This utility model relates to the field of liquid detection sampler technology, specifically a liquid detection sampler. Background Technology

[0002] As is well known, fluid sampling is often involved in industries such as chemical engineering, pharmaceuticals, environmental protection, cosmetics, and food. Through fluid sampling and analysis, and the scientific formulation of chemical elements, we develop and produce various everyday chemical products. In food testing, it is necessary to sample and test some liquid food. After a sampler is used to collect a portion of the liquid food, it is then analyzed by testing equipment. In food testing, when liquid food is involved, it is necessary to use a sampler to collect the sample.

[0003] Existing samplers can only extract one type of liquid sample at a time, resulting in low detection efficiency and high workload for testing personnel when facing major testing tasks. They are unable to extract multiple samples simultaneously. Therefore, we propose a liquid testing sampler to solve the above problems. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-3This utility model discloses a liquid detection sampler, comprising a sampling cylinder 1, a threaded liquid sampling fixing head 2 at the bottom end of the sampling cylinder 1, a positioning block 3 at the bottom end of the sampling cylinder 1, a positioning suction cup at the bottom end of the positioning block 3 to facilitate the fixing and support of the positioning block 3, a positioning sliding rod 4 at the front end of the positioning block 3, and a threaded liquid sampling fixing groove block 5 at the top end of the positioning block 3. The threaded liquid sampling fixing head 2 cooperates with the threaded liquid sampling fixing groove block 5, and the cooperation between the threaded liquid sampling fixing head 2 and the threaded liquid sampling fixing groove block 5 is a threaded engagement, allowing the threaded liquid sampling fixing head 2 to be installed and removed along the threaded liquid sampling fixing groove block 5. The threaded liquid sampling fixing groove block 5 is provided with several liquid sampling hoses 6, each of which has a... A liquid sampling needle 7 is provided at one end away from the threaded liquid sampling fixing block 5. Each liquid sampling needle 7 is equipped with a positioning slider 8. Each positioning slider 8 cooperates with the positioning slide rod 4. The cooperation between each positioning slider 8 and the positioning slide rod 4 is a sliding fit, which allows the positioning slider 8 to slide and adjust along the positioning slide rod 4, and has a certain damping effect. The edges of the sampling cylinder 1, threaded liquid sampling fixing head 2, positioning block 3, positioning slide rod 4, threaded liquid sampling fixing block 5, liquid sampling hose 6, liquid sampling needle 7 and positioning slider 8 are all rounded, so that the liquid detection sampler will not scratch the user during use. The liquid detection sampler can extract multiple liquid samples at the same time, and the detection efficiency is higher when facing heavy detection tasks.

[0021] In summary, when using this liquid detection sampler, the sampling cylinder 1 and the positioning block 3 are first fixed by the cooperation between the threaded liquid sampling fixing head 2 and the threaded liquid sampling fixing groove block 5. Then, the position of the sampling needle 7 is adjusted according to the placement of the liquid sample. If the liquid sample is placed horizontally, the distance can be adjusted by the cooperation between the positioning slider 8 and the positioning slide rod 4. Pressing the positioning block 3 causes the sampling needle 7 to take a sample. If the liquid sample is not evenly placed, the positioning slide rod 4 is not used, and the sampling needles 7 can be inserted one by one. The liquid sample can then be extracted using the sampling cylinder 1. This liquid detection sampler can extract multiple liquid samples at the same time, and the detection efficiency is higher when facing heavy detection tasks. The liquid detection sampler has a better performance.
