Description

Technical Field

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

[0002] A food safety testing sampling device is a sampling device specifically designed for the field of food testing. This device is widely used in the field of food testing technology, especially in scenarios where precise sampling is required. It can ensure the representativeness and integrity of the sample, thereby providing reliable basic data for subsequent food safety testing.

[0003] Existing equipment, such as CN212459015U, is a sampling device for food safety testing. It includes a sampling tube and a storage box. Vertical plates are fixedly connected to the bottom of both sides of the storage box's inner cavity. Threaded holes are formed in the inner cavities of the vertical plates, and threaded rods are threaded into the inner cavities of these holes. A handwheel is fixedly connected to one end of the threaded rod, and a protective pad is fixedly connected to the end of the threaded rod away from the handwheel. A sample tube is placed between the two protective pads. Insulation plates are fixedly connected to all four sides of the storage box's inner cavity. This invention, through the combined use of the storage box, vertical plates, threaded holes, threaded rods, handwheels, sample tubes, insulation plates, a semiconductor cooling chip, a flexible tube, a control valve, pads, and a disinfection lamp, offers the advantages of convenient sample storage and transport. It solves the problem of existing sampling devices for liquid food safety testing being inconvenient for storing and transporting samples after sampling.

[0004] When workers need to sample food, they place the food into the sampling device so that the device can take a sample. However, the sampling device in the comparison document uses a syringe to draw the liquid from the soup, and the worker needs to hold the storage box while taking the sample, which makes it difficult for the worker to operate the sampling device. At the same time, the syringe can be blocked by food residue when drawing the liquid, which increases the difficulty for the worker to operate the sampling device. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing technologies increase the difficulty of operation for workers using sampling devices, and to propose a sampling device for food safety testing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a sampling device for food safety testing, comprising a solid collection container, a sealing cover, and a collection device. The sealing cover is installed on the surface of the solid collection container, and the collection device is disposed on the surface of the solid collection container. The collection device includes a threaded groove, which is formed on the lower surface of the solid collection container and located below the sealing cover. A transparent measuring cylinder is threadedly connected to the inside of the threaded groove. A drainage tube is fixedly connected to one side of the transparent measuring cylinder. A sampling spoon is disposed above the drainage tube, and a filter screen is fixedly connected to the surface of the sampling spoon. A sealing opening is rotatably connected inside the drainage tube, and an adjusting block is fixedly connected to one side of the sealing opening. The adjusting block is rotatably connected to the inside of the drainage tube. An insert rod is slidably connected inside the drainage tube, and the insert rod is inserted into the inside of the adjusting block. The insert rod can cooperate with the drainage tube to guide the insert rod.

[0007] Preferably, a return spring is fixedly connected between the insertion rod and the drainage tube. The return spring is located on both sides of the closed opening, and the return spring can cooperate with the insertion rod to achieve the purpose of pulling the insertion rod.

[0008] Preferably, the surface of the transparent measuring cylinder is provided with a limiting device, the limiting device including a storage tray, the storage tray being fixedly connected to the lower surface of the transparent measuring cylinder, the storage tray being located below the closed cover, and the storage tray being able to cooperate with the transparent measuring cylinder to achieve the purpose of storing the drainage tube.

[0009] Preferably, a locking block is fixedly connected to the surface of the transparent measuring cylinder. The locking block is located below the drainage tube and can cooperate with the transparent measuring cylinder to restrict the drainage tube.

[0010] Preferably, a sleeve block is fixedly connected to the top end of the drainage tube, and one end of the sampling spoon is connected to the internal thread of the sleeve block. The sleeve block can cooperate with the drainage tube to restrict the drainage tube.

[0011] Preferably, a main block is fixedly connected to the surface of the solid collection tank. The main block is located on one side of the drainage pipe. A positioning rod is threadedly connected inside the main block. The positioning rod is located on one side of the drainage pipe. The main block can cooperate with the solid collection tank and the positioning rod to achieve the purpose of limiting the sleeve block.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up a collection device, when a worker needs to collect soup liquid, the worker places a sampling spoon into the soup container. When the sampling spoon is full of soup liquid, the worker tilts the spoon, and the soup liquid inside the spoon flows into the handle. The handle guides the soup liquid into the drainage tube, and the drainage tube guides the soup liquid into the transparent measuring cylinder. After the soup liquid is sampled, the adjusting block is rotated, which drives the sealing port to close the drainage tube. The insertion rod is then released, and the reset spring pulls the insertion rod, which is then inserted into the adjusting block. By setting up a collection device, it is possible to effectively and conveniently collect and sample soup liquid, avoiding situations where the worker is inflexible in operating the device when collecting soup liquid, thereby reducing the difficulty of using the sampling device and also reducing the possibility of food residue clogging the syringe.

[0014] In this invention, by setting a limiting device, when the worker needs to store the sampling spoon, the worker wraps the excess drainage tube around the storage tray, then locks the drainage tube onto the locking block, and then puts the sleeve block into the main block. By rotating the positioning rod, the positioning rod abuts against the sleeve block. By setting a limiting device, it is possible to effectively facilitate the worker to carry the sampling device, avoiding the situation where the drainage tube is too long when the worker carries the sampling device, thereby improving the practicality of the sampling device.

[0025] Specifically, the drainage tube 33 has a sliding connection to an insert rod 39 inside. The insert rod 39 is inserted into the adjustment block 34. The insert rod 39 can cooperate with the drainage tube 33 to guide the insert rod 39.

[0026] Specifically, a return spring 37 is fixedly connected between the insertion rod 39 and the drainage tube 33, and the return spring 37 is located on both sides of the closed opening 35.

[0027] In this embodiment, the return spring 37 can cooperate with the insertion rod 39 to achieve the purpose of pulling the insertion rod 39.

[0028] In this embodiment: a limiting device 4 is provided on the surface of the transparent measuring cylinder 38. The limiting device 4 includes a receiving tray 42, which is fixedly connected to the lower surface of the transparent measuring cylinder 38. The receiving tray 42 is located below the closed cover 2. The receiving tray 42 can cooperate with the transparent measuring cylinder 38 to achieve the purpose of receiving the drainage tube 33.

[0029] Specifically, a locking block 41 is fixedly connected to the surface of the transparent measuring cylinder 38, and the locking block 41 is located below the drainage tube 33.

[0030] In this embodiment, the card block 41 can cooperate with the transparent measuring cylinder 38 to restrict the drainage tube 33.

[0031] Specifically, a sleeve 43 is fixedly connected to the top of the drainage tube 33, and one end of the sampling spoon 32 is connected to the internal thread of the sleeve 43. The sleeve 43 can cooperate with the drainage tube 33 to restrict the drainage tube 33.
