Description

Technical Field

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

[0002] Food testing is an important means of ensuring the nutritional quality and hygiene of food and promoting human health. When there is a need to store grain, samples are taken from the stored food to ensure that the food is healthy and intact.

[0003] In related technologies, to address the problem that food can easily slip out of the sampling device during operation due to the smooth inner wall of the straight cylindrical structure, leading to sampling failure or sample contamination and significantly reducing detection efficiency, patent CN219532569U provides a layered sampling device for food detection. This layered sampling device for food detection improves the structure of the existing sampling cylinder by adding a spiral structure inside the sampling cylinder. This effectively prevents the sample from slipping out of the sampling cylinder during the sampling process, thereby ensuring sampling efficiency and indirectly guaranteeing detection efficiency. At the same time, the sampling cylinder adopts a combined structure, which facilitates the removal of samples from the sampling cylinder and also facilitates the cleaning of the inside of the sampling cylinder.

[0004] Traditional sampling equipment suffers from inaccuracies and significant errors when sampling food. This is because the internal components of some foods are unevenly distributed during growth, leading to inconsistent sampling locations and potentially affecting the assessment of food quality. Furthermore, it is inconvenient to limit the location of the sampled food during the sampling process, requiring multiple samplings from different locations. Therefore, inventing a stratified sampling device for food testing to improve these issues has become a pressing problem for those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a layered sampling device for food testing, which aims to improve the problem that different sampling positions can lead to inaccurate test results and large errors, which can easily affect the judgment of food quality.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a layered sampling device for food testing, including a base, a telescopic rod, and a threaded rod. An installation rod is fixedly installed on the top of the base. A sliding sleeve is slidably installed on the outer side of the installation rod. A sliding sleeve is movably installed on one side of the sliding sleeve. A sampling sleeve is slidably installed on the inner side of the sliding sleeve. An arc-shaped ring is limited and installed on the outer side of the sampling sleeve. The arc-shaped rings are fixedly positioned and secured by a mounting buckle. An installation plate is threadedly installed on the bottom of the base via the threaded rod. A connecting rod extending from the top of the base is fixedly installed on the top of the installation plate. A clamping plate is fixedly installed on the top of the connecting rod.

[0008] Preferably, a support column is fixedly installed at the bottom of the base, a side baffle corresponding to the clamping plate is fixedly installed at the top of the base, and the mounting rod and the sliding sleeve are limited and fixed by a fixing knob.

[0009] By adopting the above technical solution, the support column can easily support the device, making it more stable during use. At the same time, the side baffle can easily shield the outside.

[0010] Preferably, a sliding block is fixedly installed on the outer side of the sampling sleeve, and a sliding groove that cooperates with the sliding block is provided on the inner side of the sliding sleeve.

[0011] By adopting the above technical solution, the bottom of the sampling sleeve is pressed down against the food to be sampled through the cooperation between the sliding block and the sliding groove, so that the inside of the sampling sleeve can perform sampling operations on the food to be sampled, and the process of pressing down is more stable.

[0012] Preferably, the arc-shaped rings are movably mounted together via a rotating shaft, and the sliding sleeve is provided with a slot corresponding to the mounting buckle.

[0013] By adopting the above technical solution, the arc ring can rotate around the axis of rotation, making it easy to open the sampling sleeve and conveniently remove the sampled food from inside the sampling sleeve. The slot can connect with the mounting buckle, preventing obstruction as the sampling sleeve slides along the sliding sleeve.

[0014] Preferably, the threaded rod and the mounting plate are connected by a threaded sleeve, and a rotating disk is fixedly installed at one end of the threaded rod.

[0015] By adopting the above technical solution, the threaded rod can be rotated synchronously by rotating the rotating disk, thereby adjusting the thread direction of the threaded sleeve and the threaded rod, so that the mounting plate can move at the bottom of the base.

[0016] Preferably, the base is provided with a movable groove that mates with the connecting rod, and the inner side of the clamping plate is provided with a protective pad.

[0017] By adopting the above technical solution, the movable groove allows the connecting rod to slide more easily during movement, making it more stable during use, and the protective pad provides better protection when holding the food to be tested.

[0018] The beneficial effects of this utility model are:

[0019] By placing the food to be sampled on top of the base, rotating the rotating disk allows the threaded rod to rotate synchronously, thereby adjusting the thread direction of the threaded sleeve and the threaded rod. This allows the mounting plate to move at the bottom of the base. During the movement of the mounting plate, the connecting rod slides along the inside of the movable groove, allowing the clamping plate to easily limit and fix the food to be sampled. Simultaneously, the sliding sleeve slides along the outside of the mounting rod, allowing the telescopic rod to easily adjust the distance between itself and the food. By fixing the knob, the mounting rod and the sliding sleeve are limited, and the sampling sleeve slides along the inside of the sliding sleeve, allowing the sliding block and the sliding groove to engage. This presses down the bottom of the sampling sleeve against the food to be sampled, allowing the food to be sampled inside the sampling sleeve. The arc ring can rotate around the rotating axis, allowing the sampling sleeve to be easily opened, thus facilitating the removal of the sampled food from inside the sampling sleeve.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example, refer to Figure 1-5 A layered sampling device for food testing includes a base 1, a telescopic rod 2, and a threaded rod 3. An installation rod 103 is fixedly installed on the top of the base 1. A sliding sleeve 104 is slidably installed on the outer side of the installation rod 103. A sliding sleeve 201 is movably installed on one side of the sliding sleeve 104. A sampling sleeve 202 is slidably installed on the inner side of the sliding sleeve 201. An arc-shaped ring 205 is limited and installed on the outer side of the sampling sleeve 202. The arc-shaped rings 205 are limited and fixed by an installation buckle 206. An installation plate 301 is threadedly installed on the bottom of the base 1 through the threaded rod 3. A connecting rod 304 extending out of the top of the base 1 is fixedly installed on the top of the installation plate 301. A clamping plate 306 is fixedly installed on the top of the connecting rod 304. An movable groove 305 that mates with the connecting rod 304 is provided on the base 1. A protective pad is provided on the inner side of the clamping plate 306.

[0029] Furthermore, a support column 101 is fixedly installed at the bottom of the base 1, and a side baffle 102 corresponding to the clamping plate 306 is fixedly installed at the top of the base 1. The mounting rod 103 and the sliding sleeve 104 are limited and fixed by a fixing knob 105. A sliding block 203 is fixedly installed on the outer side of the sampling sleeve 202, and a sliding groove 204 that cooperates with the sliding block 203 is provided on the inner side of the sliding sleeve 201.

[0030] It should be noted that the support column 101 can easily support the device, making it more stable during use. At the same time, the side baffle 102 can easily block the outside. The sliding block 203 and the sliding groove 204 cooperate to press the bottom of the sampling sleeve 202 down with the food to be sampled, so that the inside of the sampling sleeve 202 can perform the sampling operation on the food to be sampled, which is more stable during the pressing process.

[0031] Reference Figure 3-5 Furthermore, the arc-shaped rings 205 are movably installed through the rotating shaft 208, the sliding sleeve 201 is provided with a slot 207 corresponding to the mounting buckle 206, the threaded rod 3 and the mounting plate 301 are threadedly installed through the threaded sleeve 302, and a rotating disk 303 is fixedly installed at one end of the threaded rod 3;

[0032] It should be noted that the arc ring 205 can rotate around the rotating axis 208, which allows the sampling sleeve 202 to be opened easily, so that the sampled food inside the sampling sleeve 202 can be easily taken out. The slot 207 can be connected with the mounting buckle 206, which can prevent obstruction when the sampling sleeve 202 slides along the sliding sleeve 201. By rotating the rotating disk 303, the threaded rod 3 can be rotated synchronously, so that the thread direction of the threaded sleeve 302 and the threaded rod 3 can be adjusted, thereby allowing the mounting plate 301 to move at the bottom of the base 1.

[0033] The working principle of this layered sampling device for food testing is as follows: By placing the food to be sampled on the top of the base 1, rotating the rotating disk 303 causes the threaded rod 3 to rotate synchronously, thereby adjusting the thread direction of the threaded sleeve 302 and the threaded rod 3. This allows the mounting plate 301 to move at the bottom of the base 1. During the movement of the mounting plate 301, the connecting rod 304 slides along the inside of the movable groove 305, allowing the clamping plate 306 to conveniently limit and fix the food to be sampled. Simultaneously, the sliding sleeve 104 slides along the outside of the mounting rod 103, allowing the extension... The retractable rod 2 can be easily adjusted to adjust the distance between itself and the food. The mounting rod 103 and the sliding sleeve 104 are limited by the fixing knob 105. The sampling sleeve 202 slides along the inner side of the sliding sleeve 201, so that the sliding block 203 and the sliding groove 204 cooperate. The bottom of the sampling sleeve 202 is pressed down with the food to be sampled, so that the food to be sampled can be sampled inside the sampling sleeve 202. The arc ring 205 can be rotated around the rotating axis 208, so that the sampling sleeve 202 can be opened easily, and the sampled food inside the sampling sleeve 202 can be easily taken out.

[0034] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
