Description

Technical Field

[0001] This utility model belongs to the field of sampling technology, specifically a sampling device for food testing. Background Technology

[0002] Food testing is a crucial step in ensuring food safety and quality, and the process begins with sampling. Accurate and representative sampling is the foundation for all subsequent testing and analysis, directly affecting the reliability of the test results. Sampling needs to be conducted at every stage of the food being tested, including production, processing, storage, and sales, and must strictly follow standardized sampling procedures. Only through scientific and systematic sampling can the true condition of the food be reflected to the greatest extent, providing high-quality samples for subsequent laboratory testing, thereby effectively identifying potential food safety risks. An existing authorized patent (publication number: CN221445438U) describes a sampling device for food testing that integrates sampling and storage for ease of use. However, this device, by setting the sampling structure on a round cover, results in gaps in the cover, which is not conducive to sample storage. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for food testing, comprising a sample storage tube, a tube cap connected to the top of the sample storage tube, a T-shaped operating rod movably installed through the middle of the tube cap, a corrugated sleeve fixedly connected between the upper part of the T-shaped operating rod and the top of the tube cap, two symmetrical adjusting arms at the bottom of the tube cap, the bottom of the T-shaped operating rod synchronously adjusting the two adjusting arms, and a clamp fixedly installed at the bottom of each of the two adjusting arms.

[0004] Preferably, two U-shaped rods are symmetrically fixedly installed at the bottom of the tube cover, and the upper parts of the two adjusting arms are rotatably connected to the middle parts of the two U-shaped rods respectively.

[0005] Preferably, a connecting circular plate is fixedly installed at the bottom of the T-shaped operating rod under the tube cover. Two squeezing rods are symmetrically rotatably connected to the bottom of the connecting circular plate. A rotating adjusting rod is rotatably connected to the bottom of each squeezing rod. One end of each rotating adjusting rod is fixedly connected to the top of the two adjusting arms. A return spring is sleeved in the middle of the T-shaped operating rod, so that the adjusting arms can be effectively rotated and adjusted to enable the two clamping plates to perform food clamping and sampling operations.

[0006] Preferably, a first sealing ring is fixedly installed on the top of the connecting circular plate to prevent the sample from entering the interior of the corrugated sleeve. The tube cap and the sample storage tube are connected by threads, and a second sealing ring is installed at the bottom of the tube cap to connect and seal with the sample storage tube.

[0007] Preferably, the materials of the corrugated sleeve, the first sealing ring, and the second sealing ring include rubber, silicone, polypropylene, or polyethylene.

[0008] Preferably, both the sample storage tube and the tube cap are circular in shape, and the circumference of the tube cap is provided with a plurality of operating grooves at equal intervals.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This sampling device not only has an integrated structure for sampling and storage, but also has a sealing and leak-proof function, which is conducive to sample storage. In addition, the sampling device has a simple structural design, is convenient to use and operate, and has stable and reliable sampling and storage. Its performance can meet the needs of food testing sampling. During sampling and operation, the user holds the tube cap with one hand, pinching it between the thumb and middle finger, and placing the index finger at the bottom of the T-shaped operating lever. Then, by pressing the T-shaped operating lever with the index finger, the user moves the T-shaped operating lever downward. The downward movement of the T-shaped operating lever compresses the return spring and the bellows sleeve. At the same time, the downward movement of the T-shaped operating lever moves the connecting circular plate and the two squeezing rods downward. The downward movement of the two squeezing rods pushes the top of the two adjusting arms through the two rotating adjusting rods, causing the two adjusting arms to rotate. The rotation of the two adjusting arms causes the two clamping plates to move relative to each other to perform the clamping operation, thereby enabling effective food sampling. After sampling, the sample is placed inside the storage tube. Then, the index finger releases the T-shaped operating lever. The elastic restoring force of the return spring and the corrugated sleeve causes the T-shaped operating lever to move upward and reset. The upward movement of the T-shaped operating lever causes the connecting disc and the two squeezing rods to move upward, and the two clamps are separated by the two rotating adjusting rods and the two adjusting arms, allowing the sample to fall into the storage tube. Then, the tube cap is attached to the top of the storage tube and sealed with the second sealing ring. The upward movement of the connecting disc also effectively seals the tube with the first sealing ring, thus ensuring the safety of sample storage. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0013] Depend on Figures 1 to 3 As shown, the present invention includes a sample storage tube 1, and a tube cap 2 is connected to the top of the sample storage tube 1. Both the sample storage tube 1 and the tube cap 2 are circular in shape, and the circumferential surface of the tube cap 2 is provided with a plurality of operating grooves 14 at equal intervals, so that the tube cap 2 can be rotated effectively, and the tube cap 2 can be held and sampled stably.

[0014] A T-shaped operating rod 3 is movably installed through the middle of the tube cap 2. The upper part of the T-shaped operating rod 3 is circular. A corrugated sleeve 4 is fixedly connected between the upper part of the T-shaped operating rod 3 and the top of the tube cap 2. The corrugated sleeve 4 can effectively seal the gaps on the tube cap 2. Two adjusting arms 5 are symmetrically installed at the bottom of the tube cap 2, located inside the sample storage tube 1 and adjustable by rotation. The bottom of the T-shaped operating rod 3 adjusts the two adjusting arms 5 synchronously. A clamp 6 is fixedly installed at the bottom of each of the two adjusting arms 5.

[0015] Two U-shaped rods 7 are symmetrically fixedly installed at the bottom of the tube cap 2. The upper parts of the two adjusting arms 5 are rotatably connected to the middle of the two U-shaped rods 7 respectively. A connecting round plate 8 is fixedly installed at the bottom of the lower part of the tube cap 2. Two squeezing rods 9 are symmetrically rotatably connected to the bottom of the connecting round plate 8. Rotating adjusting rods 10 are rotatably connected to the bottom of the two squeezing rods 9 respectively. One end of the two rotating adjusting rods 10 is fixedly connected to the top of the two adjusting arms 5 respectively. A return spring 11 is sleeved in the middle of the T-shaped operating rod 3. The return spring 11 is located inside the corrugated sleeve 4, and both ends of the corrugated sleeve 4 are fixedly connected to the tube cap 2 and the T-shaped operating rod 3 respectively. This allows the adjusting arms 5 to be rotated and adjusted so that the two clamping plates 6 can perform food clamping and sampling operations.

[0016] A first sealing ring 12 is fixedly installed on the top of the connecting circular plate 8. The first sealing ring 12 can effectively seal the tube cap 2 and the connecting circular plate 8, preventing the sample from entering the interior of the corrugated sleeve 4. The tube cap 2 and the sample storage tube 1 are connected by threads, and a second sealing ring 13 is installed at the bottom of the tube cap 2 to connect and seal with the sample storage tube 1. The second sealing ring 13 makes the connection between the tube cap 2 and the sample storage tube 1 tighter, thereby achieving a sealing effect. The materials of the corrugated sleeve 4, the first sealing ring 12 and the second sealing ring 13 include rubber, silicone, polypropylene or polyethylene. The corrugated sleeve 4, the first sealing ring 12 and the second sealing ring 13 made of the above materials have good flexibility and sealing performance, effectively ensuring the sealing performance.

[0017] Specifically, during sampling and operation, the user holds the tube cap 2 with one hand, pinching it with the thumb and middle finger, and placing the index finger at the bottom of the T-shaped operating lever 3. Then, the user presses the T-shaped operating lever 3 with the index finger to move it down. The downward movement of the T-shaped operating lever 3 compresses the return spring 11 and the corrugated sleeve 4. At the same time, the downward movement of the T-shaped operating lever 3 drives the connecting circular plate 8 and the two squeezing rods 9 to move down. The downward movement of the two squeezing rods 9 pushes the top of the two adjusting arms 5 through the two rotating adjusting rods 10, causing the two adjusting arms 5 to rotate. The rotation of the two adjusting arms 5 drives the two clamping plates 6 to move relative to each other to perform the clamping operation, thereby enabling effective food sampling. After sampling is completed, the sample is placed inside the sample storage tube 1. Then, the index finger releases the T-shaped operating rod 3. The elastic restoring force of the return spring 11 and the corrugated sleeve 4 will cause the T-shaped operating rod 3 to move upward and reset. The upward movement of the T-shaped operating rod 3 will drive the connecting circular plate 8 and the two squeezing rods 9 to move upward. Through the two rotating adjusting rods 10 and the two adjusting arms 5, the two clamping plates 6 will be separated, so that the sample falls into the sample storage tube 1. Next, the cap 2 is connected to the top of the sample storage tube 1 and sealed by the second sealing ring 13; the upward movement of the connecting circular plate 8 can also be effectively sealed by the first sealing ring 12, thereby ensuring the safety of sample storage.

[0018] This sampling device not only has an integrated sampling and storage structure, but also has a sealing and leak-proof function, which is beneficial to sample storage. In addition, the sampling device has a simple structural design, is easy to use and operate, and has stable and reliable sampling and storage. Its performance can meet the needs of food testing sampling.
