Description

Technical Field

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

[0002] In the field of food testing, sampling of liquid foods is a crucial step, as it directly affects the accuracy and reliability of test results. Food safety is of utmost concern to the general public. Food inspection is a discipline that studies and evaluates the quality and changes of food, mainly by taking samples from the main body for testing to ensure that the product quality is up to standard.

[0003] Currently, most traditional sampling methods rely on manual operation, making it difficult to ensure that the sample volume is completely consistent each time. This directly affects the accuracy and comparability of subsequent test results. At the same time, due to the instability of manual operation, contamination during the sampling process is also prone to occur, which in turn affects the accuracy of test results. Furthermore, for scenarios that require simultaneous testing of multiple liquid foods, traditional sampling methods usually need to be performed one by one, which is not only inefficient but also prone to errors.

A spring 5 is fixedly connected within the groove 3. An electric telescopic rod 6 is fixedly connected to the top plate 4. A bracket 7 is fixedly connected to one end of the electric telescopic rod 6. A rotating rod 8 is rotatably connected through the bracket 7. The rotating rod 8 is provided with a bidirectional thread 9. A handle 10 is fixedly connected to one end of the rotating rod 8. Clamping plates 11 are threaded to both sides of the bidirectional thread 9. A limiting device is provided on the bracket 7. The clamping plate 11 slides within the limiting groove 12. It is equipped with three sets of containers 14 and sampling tubes 15, which can extract three different types of liquid food at the same time. During sampling, the amount of samples taken from the three sets of samples is the same. The sampling tube 15 is placed in the through hole 20 on the top plate 4. At this time, the bottom of the three sets of sampling tubes 15 can be kept horizontal by the limiting ring 23. The sampling tube 15 can be clamped and fixed by rotating the bolt 21 and pushing the push plate 22, which ensures the stability during sampling. The scale line 19 is provided for easy observation of the amount of sample taken.

[0027] The base plate 1 has a placement groove 13, and a container 14 is placed in the placement groove 13. A rubber stopper 16 slides inside the sampling tube 15. A pull rod 17 is fixedly connected to the upper end of the rubber stopper 16, and a pull handle 18 is fixedly connected to one end of the pull rod 17. The sampling tube 15 has a scale line 19, and a limiting ring 23 is provided at the top of the sampling tube 15. The top plate 4 has a through hole 20, through which the sampling tube 15 slides. A bolt 21 is threadedly connected to one side of the top plate 4. A push plate 22 is rotatably connected to one end of the bolt 21. The push plate 22 slides inside the top plate 4 and is in contact with the sampling tube 15. The vertical plate 2 is set perpendicular to the base plate 1. There are four sets of sliding grooves 3. One end of the spring 5 is fixedly connected to the top plate 4. The bracket 7 is U-shaped. There are three sets of bidirectional threads 9 evenly distributed on the rotating rod 8. One end of the clamping plate 11 is arc-shaped. Each set of bidirectional threads 9 has two sets of clamping plates 11. For symmetrical arrangement, container 14 is located directly below sampling tube 15. Container 14, sampling tube 15, and through hole 20 are each provided in three sets. Limiting ring 23 is located between two sets of clamping plates 11. The size of limiting ring 23 is larger than the size of sampling tube 15. Limiting ring 23 fits against the top of top plate 4. Scale line 19 and container 14 are both made of transparent material. By rotating rotating rod 8, the clamping plates 11 on each set of bidirectional threads 9 can move simultaneously towards the center under the action of bidirectional threads 9, clamping and fixing pull handle 18. Pressing top plate 4 slides in sliding groove 3, allowing sampling tube 15 to be inserted into container 14 for sampling. Finally, activating electric telescopic rod 6 pushes bracket 7, which can cause pull handle 18 to drive pull rod 17 to raise rubber stopper 16, thereby sampling liquid food in container 14. The operation is simple and convenient, and a placement groove 13 is provided to position container 14, improving the practicality of this device.

[0028] The working principle of this utility model is as follows: In use, the operator first places three containers 14 containing the food liquid to be tested into the placement groove 13 on the base plate 1. Then, the sampling tube 15 is inserted into the through hole 20 on the top plate 4. At this time, the bottom of the limiting ring 23 is attached to the top of the top plate 4. Next, the operator manually rotates the bolt 21 to push the push plate 22 towards the vertical plate 2, clamping and fixing the sampling tube 15. Then, the operator manually rotates the handle 10 to drive the rotating rod 8 to rotate. Under the action of the three sets of bidirectional threads 9, the two sets of clamping plates 11 on each set of bidirectional threads 9 slide simultaneously towards the center within the limiting groove 12, clamping and fixing the pull handle 18. Then, press the top plate 4 to move the sampling tube 15 clamped inside the top plate 4 downward. At this time, the top plate 4 slides downward in the slide groove 3 and compresses the spring 5, inserting into the appropriate position inside the container 14. Then, start the electric telescopic rod 6 to push the bracket 7 upward. The bracket 7 drives the clamped pull handle 18 to pull the pull rod 17 and the rubber stopper 16 to slide upward in the sampling tube 15, thereby drawing an equal amount of liquid food in the container 14 into the sampling tube 15. After sampling is completed, release the top plate 4. Under the action of the spring 5, the top plate 4 is pushed back. Then, rotate the bolt 21 and the rotating rod 8 in the opposite direction to take out the sampling tube 15 after sampling.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this.
