Description

Technical Field

[0001] This utility model belongs to the field of food sampling technology, and in particular relates to a food sampling and testing sampler. Background Technology

[0002] Food testing is a crucial means of ensuring food safety and quality. It involves conducting comprehensive testing on food to ensure that it meets relevant standards during production, processing, transportation, and storage, thus protecting consumers' health and rights. Typically, food undergoes sampling and testing before sale to ensure compliance. This process requires sampling food products destined for sale and delivery to relevant testing institutions. However, the following drawbacks still exist in the sampling process:

[0003] Conventional sampling, based on the form of food, can be roughly divided into sampling of solid food (such as bread, rice, flour, etc.) and sampling of liquid food. However, most samplers can only meet the sampling requirements of one type and cannot meet the sampling requirements of food in different states of solid and liquid.

[0004] Secondly, when sampling solid foods, such as powdered foods, it is usually necessary to insert a sampler deep into the food to retrieve the deep-seated food for testing. This typically involves using a sampling tube with a pointed end to pierce the food. However, this method has several problems. First, because the sampling tube is a through-hole structure, when inserted deep into the food from above, all the food along the insertion path remains inside the tube, resulting in inaccurate sample acquisition and wasted sample. Second, for powdered foods, during the removal of the sampling tube, some food may fall back into the tube, ultimately yielding only a small sample at the very end, which may not be from the deeper parts of the food, leading to inaccurate subsequent testing. Utility Model Content

[0005] The purpose of this utility model is to provide a food sampling and testing sampler. By setting up a sampling tube, control lever, adjustment lever, sealing plate, threaded ring, and hinge, it solves the problems that the same sampler cannot meet the sampling of foods in different solid and liquid states, and that when sampling solid samples, food will remain in the sampling tube along the entire sampling path, making it impossible to obtain samples at precise locations and causing waste. In addition, powdery samples may fall back when the sampling tube is pulled out.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a food sampling and testing sampler, comprising a sampling tube, a control rod, an adjusting rod, a sealing plate, a hinge, and a threaded ring. The control rod is movably inserted into the sampling tube, and a piston is fixed at the bottom end of the control rod extending into the sampling tube. An adjusting rod is provided on the outside of the sampling tube, and a base block is rotatably connected to the bottom outer circumference of the adjusting rod. A sealing plate is connected to the inclined insertion port at the bottom end of the sampling tube through a hinge. A limiting groove is formed on the lower inclined surface of the sealing plate. A limiting rod is fixed on the side of the base block near the sealing plate, and the ball end of the limiting rod is slidably disposed in the limiting groove. A threaded ring is threadedly connected to the sampling tube above the sealing plate.

[0008] Furthermore, the outer wall of the piston contacts the inner wall of the sampling tube, and the upper end of the control lever extends out of the sampling tube, the diameter of the control lever being smaller than the inner diameter of the sampling tube.

[0009] Furthermore, the sampling tube is fixed with three mounting ears on its outer periphery, and the adjusting rod is inserted into the three mounting ears. The upper outer periphery of the adjusting rod is provided with a threaded section, and the threaded section of the adjusting rod is screwed into the uppermost mounting ear.

[0010] Furthermore, a diagonal rod is fixed to the upper part of the sampling tube, and a handle is fixed to the upper end of the diagonal rod.

[0011] Furthermore, the bottom end of the control lever extends beyond the bottom end of the base block and is fixed with a plug.

[0012] Furthermore, the hinge includes two hinge ears and a hinge shaft. The two ends of the hinge shaft are rotatably connected to the two hinge ears. The two hinge ears are fixed to the upper part of the oblique insertion port at the bottom of the sampling tube, while the outer periphery of the hinge shaft is fixed to the upper end of the sealing plate.

[0013] Furthermore, a rubber nozzle is fixedly fixed through the bottom of the threaded ring, and ear plates are symmetrically fixed on the outer periphery of the rubber nozzle.

[0014] This utility model has the following beneficial effects:

[0015] This invention solves the problem that the same sampler cannot sample foods in different states, such as solid and liquid, by setting up a sampling tube, control lever, adjustment lever, sealing plate, and threaded ring. When sampling solid foods, the sampling tube and sealing plate are inserted into the food as a whole. Then, the sealing plate is opened by adjusting the lever, and the tube is inserted further into the food to obtain a certain amount of sample. The bottom of the sampling tube is then sealed with the sealing plate, and the sampling tube can be removed. When sampling liquid foods, the threaded ring is installed into the sampling tube, and the bottom of the sampling tube is directly inserted into the sampling position of the food. The control lever is moved upward to move the piston upward, thereby using the nozzle to draw the liquid sample into the sampling tube.

[0016] This invention solves the problems of food residue remaining in the sampling tube along the entire sampling path during solid sample sampling, resulting in inaccurate sample acquisition and waste, and the possibility of powdered samples falling back into the tube when it is pulled out. When sampling solid food, the threaded ring is removed, the sealing plate closes the bottom of the sampling tube, and the entire tube is inserted into the food. During this process, food along the sampling path will not enter the sampling tube until the designated sampling location is reached. The adjusting rod is then rotated downwards to gradually open the sealing plate, allowing the sampling tube to be inserted to a certain depth. The sample at the designated location is then obtained inside the tube. The adjusting rod is then rotated upwards to close the bottom of the sampling tube again, and finally the tube is pulled out. Throughout this process, the sample in the sampling tube will not fall back into the tube, facilitating accurate sample retention. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-7 As shown, this utility model is a food sampling and testing sampler, including a sampling tube 1, a control rod 2, an adjusting rod 3, a sealing plate 4, a hinge 5, and a threaded ring 6. The control rod 2 is movably inserted into the sampling tube 1, and a piston 201 is fixed at the bottom end of the control rod 2 that extends into the sampling tube 1. An adjusting rod 3 is provided on the outside of the sampling tube 1, and a base block 302 is rotatably connected to the bottom outer circumference of the adjusting rod 3. The sealing plate 4 is connected to the inclined insertion port at the bottom end of the sampling tube 1 through the hinge 5. A limiting groove 401 is opened on the lower inclined surface of the sealing plate 4. A limiting rod 3021 is fixed on the side of the base block 302 near the sealing plate 4, and the ball head of the limiting rod 3021 is slidably disposed in the limiting groove 401. A threaded ring 6 is threadedly connected to the sampling tube 1 above the sealing plate 4.

[0029] The sampling tube 1 serves as the main sampling container. Its bottom end is hinged to the sealing plate 4 via the hinge 5. The sealing plate 4 can close the oblique insertion port at the bottom of the sampling tube 1 to prevent unnecessary samples from entering the sampling tube 1 during the sampling process. By rotating and raising the adjusting rod 3, the height position of the base block 302 can be changed, thereby changing the position of the limiting rod 3021. The limiting rod 3021 will slide in the limiting groove 401 in the sealing plate 4, thereby controlling whether the sealing plate 4 is opened or closed.

[0030] The outer wall of piston 201 contacts the inner wall of sampling tube 1, and the upper end of control lever 2 extends out of sampling tube 1. The diameter of control lever 2 is smaller than the inner diameter of sampling tube 1.

[0031] When taking liquid samples, the threaded ring 6 is installed inside the sampling tube 1. By pulling the control lever 2 upward, the piston 201 is driven to rise, creating a negative pressure inside the sampling tube 1 below the piston 201. Then, the external liquid sample is sucked into the sampling tube 1 through the nozzle 601 at the bottom of the threaded ring 6.

[0032] The outer periphery of the sampling tube 1 is fixed with three mounting ears 103, and the adjusting rod 3 is inserted into the three mounting ears 103. The upper outer periphery of the adjusting rod 3 is provided with a threaded section 301, and the threaded section 301 of the adjusting rod 3 is screwed into the uppermost mounting ear 103.

[0033] The design of three mounting ears 103 helps to stabilize the adjusting rod 3 during production, avoids deviation and other effects, and keeps the adjusting rod 3 in the center. The setting of the upper threaded section 301 of the adjusting rod 3 allows the adjusting rod 3 to be raised and lowered after rotation, thereby changing the height position of its bottom base block 302.

[0034] A diagonal rod 101 is fixed to the upper part of the periphery of the sampling tube 1, and a handle 102 is fixed to the upper end of the diagonal rod 101. The sampling tube 1 can be controlled by holding the handle 102 through the diagonal rod 101, which is convenient for operation and use.

[0035] The bottom end of the control lever 2 extends out of the bottom end of the base block 302 and is fixed with a plug 303.

[0036] The hinge 5 includes two hinge ears 501 and a hinge shaft 502. The two ends of the hinge shaft 502 are rotatably connected to the two hinge ears 501. The two hinge ears 501 are fixed to the upper part of the oblique insertion port at the bottom end of the sampling tube 1, while the outer periphery of the hinge shaft 502 is fixed to the upper end of the sealing plate 4.

[0037] The hinge 5 is provided to facilitate the hinge connection between the bottom ends of the sealing plate 4 and the sampling tube 1.

[0038] A nozzle 601 is fixed through the bottom of the threaded ring 6, and ear plates 602 are symmetrically fixed on the outer periphery of the nozzle 601. The nozzle 601 reduces the suction area of ​​the threaded ring 6, forming a nozzle structure similar to a syringe, which facilitates the suction of liquid. The ear plates 602 facilitate the rotation of the threaded ring 6 into the sampling tube 1.

[0039] The specific working principle of this utility model is as follows: First, when sampling solid food, the threaded ring 6 is removed. At this time, the sealing plate 4 seals the bottom end of the sampling tube 1. The sampling tube 1 is inserted into the food. During this process, due to the obstruction of the sealing plate 4, the food in the sampling path will not enter the sampling tube 1 until the designated sampling location is reached. The rotating adjustment rod 3 moves down, causing the base block 302 to move down, thereby changing the height position of the limiting rod 3021. The limiting rod 3021 will slide down in the limiting groove 401 in the sealing plate 4, thereby controlling the sealing plate 4 to open. At this time, the sampling tube 1 is inserted to a certain depth, and the sample at the designated location will be obtained in the sampling tube 1. Then, the rotating adjustment rod 3 moves up, continuing to seal the bottom end of the sampling tube 1 with the sealing plate 4. Finally, the sampling tube 1 can be pulled out. During this process, the sample in the sampling tube 1 will not fall back.

[0040] When sampling liquid food, the threaded ring 6 is installed into the sampling tube 1, and the bottom end of the sampling tube 1 is directly inserted into the sampling position of the food. The control lever 2 is moved up, causing the piston 201 to move up, thereby using the nozzle 601 to draw the liquid sample into the sampling tube 1 to complete the sampling.

[0041] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
