Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically a convenient food testing and extraction device. Background Technology

[0002] A sample extraction device is a device that extracts samples from the object being tested. Sampling is generally random and conducted in a dispersed manner to obtain more representative samples and more accurate and scientific data. In the current vegetable sampling process, most samples are obtained by randomly picking vegetables and cutting them. In the process of cutting and sampling, multiple cuts are often required to achieve the appropriate sampling standards and regularity.

[0003] A search revealed a published patent: CN221302800U, which discloses a sample extraction device for food testing, belonging to the field of food testing technology. It includes a bottom support plate and an upper pressure plate, with the upper pressure plate movably connected to the bottom support plate. A lower capsule is connected to the bottom support plate, and the upper capsule is externally connected to the upper pressure plate. During sampling, the user can expand the lower and upper capsules as needed. As the upper and lower capsules expand, a semi-rigid rubber cutter is also stretched. Once the upper and lower capsules expand to a specified area, they are cut, allowing the user to easily sample different sized vegetable samples at once.

[0004] However, the following issues may arise during the use of this device: Since the device uses upper and lower semi-hard rubber blades to cut and sample vegetables for testing, the blades are exposed after use due to the lack of a protective device. Hard objects in the external environment can easily damage the blades, affecting their daily use and reducing the device's lifespan. Furthermore, impurities and other contaminants in the external environment can easily adhere to the blades, contaminating them and consequently the vegetables. To address these issues, technological innovations are needed based on the existing device. Summary of the Invention

A first threaded rod 10 extending to the outside of the movable groove 17 is rotatably connected to the interior of the movable groove 17. The surface of the first threaded rod 10 is threadedly connected to the interior of the movable block 18. By rotating the first threaded rod 10, the first threaded rod 10 drives the movable block 18 to slide, and the movable block 18 can drive the second fixed block 15 to slide.

[0024] The surface of the protective frame 4 has two symmetrical second fixing grooves 16, and the second fixing block 15 is inserted into the interior of the second fixing groove 16.

[0025] The operator places the protective frame 4 on the base plate 1, and the bottom of the protective frame 4 slides into the fixed slot 11. Then, the operator rotates the upper pressure plate 2 and makes the semi-hard rubber cutter at the bottom of the upper pressure plate 2 fit tightly with the semi-hard rubber cutter inside the protective frame 4. Then, the operator rotates the first threaded rod 10, which drives the moving block 18 to slide. The moving block 18 drives the second fixing block 15 to slide into the second fixing slot 16 for insertion. By fixing the protective frame 4 and making the rubber layer inside the protective frame 4 fit tightly with the cutter surface, the semi-hard rubber cutter can be protected to a certain extent.

[0030] The first fixing block 14 is internally inserted into the first fixing groove 9.

[0031] By pressing the second pressure plate downwards, the bottom of the transmission rod 7 slides into the transmission groove 8. Then, the operator rotates the second threaded rod 12, which drives the two first fixing blocks 14 to move relative to each other. The two first fixing blocks 14 slide into the first fixing groove 9 and are inserted. By fixing the transmission rod 7 inside the transmission groove 8, the operator can easily fold and fix the device, making it smaller in size when not in use. This makes it easier for the operator to carry the device and reduces the problem of the device being too large to carry and taking up too much space, making the device more convenient to use.

[0032] Working principle: For this type of convenient food testing and extraction device, the operator first rotates the first threaded rod 10, which drives the moving block 18 to slide. The moving block 18 can drive the second fixed block 15 to slide into or out of the second fixed groove 16, making it convenient for the operator to protect and use the cutter. The operator then presses the second pressure plate down, causing the bottom of the transmission rod 7 to slide into the transmission groove 8. Then, the operator rotates the second threaded rod 12, which drives the two first fixed blocks 14 to move relative to each other. The two first fixed blocks 14 slide into the first fixed groove 9 and are inserted. By fixing the transmission rod 7 inside the transmission groove 8, the operator can easily fold and fix the device.
