Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] See also Figure 1-5, a sampling device for detecting the metal content of food raw materials, comprising a main body 1, a leakage prevention mechanism and a removal mechanism, the leakage prevention mechanism comprising a protective sleeve 2, a first spring 3, a clamping strip 4, a leakage prevention plate 5, a second spring 6 and a baffle 7, the protective sleeve 2 is mounted on the main body 1 and is slidably connected to the main body 1, the first spring 3 is mounted on the leakage prevention plate 5, and its two ends are fixedly connected to the leakage prevention plate 5 and the clamping strip 4 respectively, the clamping strip 4 is detachably connected to the main body 1, the leakage prevention plate 5 is mounted on the bottom of the main body 1 and is detachably connected to the main body 1, the second spring 6 is fixedly mounted inside the main body 1, the baffle 7 is mounted inside the main body 1 and is slidably connected to the main body 1, and the other end of the second spring 6 is fixedly connected to the baffle 7, the removal mechanism comprises a removal piece 8, a connecting sleeve 9, a rotating sleeve 10 and a connecting rod 11, the removal piece 8 is an external component, the connecting sleeve 9 is fixedly connected to the connecting rod 11, and the other end of the connecting rod 11 is fixedly connected to the protective sleeve 2, the rotating sleeve 10 is mounted on the connecting sleeve 9 and is slidably connected to the main body 1.

[0030] In this embodiment, the anti-leakage mechanism includes a protective cover 2, a first spring 3, a card strip 4, a leak-proof plate 5, a second spring 6 and a baffle 7. When in use, the main rod 16 is held to place the main body 1 into the container containing the sample, and then the sample enters the main body 1 through the sampling port 27 on the main body 1 to complete the collection. When the collection is completed, the protective cover 2 is pushed. At this time, the protective cover 2 slides on the main body 1 and wraps the main body 1, and the rubber ring 12 and the sealing plate 13 on the protective cover 2 enter the first sealing groove 14 and the second sealing groove 15 in the main body 1, so that the sample inside the main body 1 is not easy to leak during transportation, and prevents contact with the outside air to cause the internal sample to deteriorate. During the sampling process, the card strip 4 is in the card hole 28, so that the leak-proof plate 5 is tightly installed inside the main body 1, and the baffle 7 is tightly fitted with the pressure plate 23 due to the action of the second spring 6, thereby preventing the sample inside the main body 1 from leaking.

[0031] In this embodiment, the removal mechanism includes a removal piece 8, a connecting sleeve 9, a rotating sleeve 10 and a connecting rod 11. When in use, the removal piece 8 is placed in a large container, and the card strip 4 is pulled to make the card sleeve slide inside the sliding sleeve 20 and compress the first spring 3. At this time, the through rod 21 slides in the through hole 22, and the card strip 4 also disengages from the card hole 28. When the leak-proof plate 5 is removed, the main body 1 is pressed onto the removal piece 8. The ejector rod 26 on the removal piece 8 pushes the baffle 7, and the second spring 6 in the groove on the pressure plate 23 is stretched. As the baffle 7 moves, a gap is generated between the baffle 7 and the main body 1, and the sample flows out of the leak hole 25 of the removal piece 8 to the quasi-sample. In the prepared container, the sample is then removed. During the sampling and removal process, the operator always slides the protective cover 2 on the main body 1. When in use, pull the rotating cover 10 to slide on the main rod 16, and pull the connecting cover 9 to make the connecting rod 11 drive the protective cover 2, so that the protective cover 2 is separated from the main body 1. The rotating cover 10 rotates all the time during this process, so that the short rod 17 on the main rod 16 is located at the bottom of the stop groove 18 from the top of the stop groove 18, thereby completing the separation of the protective cover 2 from the main body 1. After completing a sampling, the disassembled components are rinsed at this time. Because the device is easy to disassemble and has no dead angles, it is easy to clean and can be put into use again quickly.

[0032] Example 2:

[0033] In summary, when in use, hold the main rod 16 and place the main body 1 into the container for holding the sample, and then the sample enters the main body 1 through the sampling port 27 on the main body 1 to complete the collection. When the collection is completed, push the protective cover 2. At this time, the protective cover 2 slides on the main body 1 and wraps the main body 1, and the rubber ring 12 and the sealing plate 13 on the protective cover 2 enter the first sealing groove 14 and the second sealing groove 15 in the main body 1, so that the sample inside the main body 1 is not easy to leak during transportation, and prevents contact with the outside air to cause the internal sample to deteriorate. During the sampling process, the card strip 4 is in the card hole 28 at this time, so that the leak-proof plate 5 is tightly installed inside the main body 1, and the baffle 7 is tightly fitted with the pressure plate 23 due to the action of the second spring 6, thereby preventing the sample inside the main body 1 from leaking. When the sample is taken, start to take out the sample, place the take-out piece 8 into the large container, pull the card strip 4, so that the card sleeve slides inside the sliding sleeve 20, and compresses the first spring 3. At this time, the through rod 21 slides in the through hole 22, and the card The strip 4 also disengages from the card hole 28. When the leak-proof plate 5 is removed, the main body 1 is pressed onto the removal piece 8. The ejector rod 26 on the removal piece 8 pushes the baffle 7, and the second spring 6 in the groove on the pressure plate 23 is stretched. As the baffle 7 moves, a gap is generated between the baffle 7 and the main body 1, and the sample flows out of the leak hole 25 of the removal piece 8 into the prepared container, and then the sample is taken out. In the process of sampling to taking out, the operator always slides the protective cover 2 on the main body 1. When in use, Pull the rotating sleeve 10 to slide on the main rod 16, pull the connecting sleeve 9 so that the connecting rod 11 drives the protective sleeve 2, thereby separating the protective sleeve 2 from the main body 1, and the rotating sleeve 10 keeps rotating during this process, so that the short rod 17 on the main rod 16 is located from the top of the stop groove 18 to the bottom of the stop groove 18, thereby completing the separation of the protective sleeve 2 from the main body 1. After completing a sampling, the disassembled components are rinsed at this time. Because the device is easy to disassemble and has no dead angles, it is easy to clean and can be put into use again quickly.

[0034] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
