Description

Technical Field

[0001] The utility model relates to a quantitative sampling device, which relates to the technical field of food detection. Background Art

[0002] Food safety is of the utmost concern to the general public. Whether food safety is safe or not is directly related to people's physical health and even life safety. In order to ensure food safety, the national food safety supervision department will periodically conduct sampling and testing on various foods circulating in the market. Sampling devices are required in the sampling and testing process.

[0003] The existing quantitative sampling device refers to patent document CN211374114U. The device proposed in the patent document can quantitatively sample and store food, has high sampling accuracy, and can also avoid contact between operators and food, thereby preventing food from being contaminated, improving detection results, and is simple to operate and easy to use.

[0004] However, the above device can only detect jelly-like foods and cannot conveniently perform quantitative sampling on liquid foods. In order to further expand the scope of application of the device and enable it to meet different sampling needs, a quantitative sampling device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-Figure 4 This embodiment proposes a quantitative sampling device, including a liquid sampling tube 1, a semi-solid sampling tube 2 and a quantitative mechanism 3.

[0025] The bottom end of the liquid sampling tube 1 is connected to a liquid suction port 4 , and a sealing plug is provided at the bottom end of the liquid suction port 4 . The sealing plug can prevent the liquid in the liquid sampling tube 1 from leaking out.

[0026] The outer surface of the liquid sampling tube 1 is provided with a first measuring range 7. The provision of the liquid suction port 4 facilitates the sampling of liquid food, and the provision of the first measuring range 7 is beneficial to the quantitative sampling work.

[0027] A sampling head 5 is installed at the bottom end of the semi-solid sampling tube 2, and a protective cover 6 is provided on the outside of the sampling head 5. A second measuring range 8 is opened on the outer surface of the semi-solid sampling tube 2, and an anti-slip cover 9 is fixedly connected to the outer surfaces of the liquid sampling tube 1 and the semi-solid sampling tube 2.

[0028] By setting the sampling head 5, quantitative sampling of semi-solid foods like jelly can be facilitated. By setting the second measuring range 8, it is beneficial to the work of quantitative sampling. By setting the anti-slip sleeve 9, it is convenient for staff to hold the liquid sampling tube 1 or the semi-solid sampling tube 2, thereby facilitating the work of quantitative sampling.

[0029] The quantitative mechanism 3 includes a connecting plate 301 , the bottom surfaces of which are fixedly connected to the upper surfaces of the liquid sampling tube 1 and the semi-solid sampling tube 2 on both sides, and the inner wall of the connecting plate 301 is threadedly connected to two threaded rods 302 .

[0030] The inner wall sliding sleeve of the liquid sampling tube 1 is provided with a first baffle 303 and a piston 304 , and the upper surface of the piston 304 is fixedly connected to two connecting rods 305 .

[0031] Both sides of the first baffle 303 are slidably mounted on the two connecting rods 305 , and the upper surface of the first baffle 303 is rotatably connected to the bottom end of the corresponding threaded rod 302 .

[0032] When the threaded rod 302 is rotated above the first baffle 303, the first baffle 303 can be moved along the two connecting rods 305 in the inner wall of the liquid sampling tube 1. In this way, the first baffle 303 can be moved to the specified position according to the first measuring range 7, which facilitates the quantitative sampling of liquid food.

[0033] A handle 306 is provided above the liquid sampling tube 1 . The top ends of the two connecting rods 305 are fixedly connected to the bottom surface of the handle 306 . The two connecting rods 305 are slidably sleeved on the inner wall of the connecting plate 301 .

[0034] By setting up the handle 306, the piston 304 can be controlled to move in the inner wall of the liquid sampling tube 1 through the two connecting rods 305. When the staff pulls the handle 306 upward, the liquid food can be sucked into the liquid sampling tube 1 through the liquid suction port 4. When the piston 304 moves to contact the first baffle 303, it can no longer move upward, thereby realizing the quantitative sampling of the liquid food.

[0035] A through hole 307 is provided on the surface of the handle 306. The threaded rod 302 on the left of the two threaded rods 302 passes through the through hole 307 and extends to the top of the handle 306. By providing the through hole 307, the movement of the handle 306 will not interfere with the state of the threaded rod 302.

[0036] The top ends of the two threaded rods 302 are fixedly connected with knobs 310 , and the outer surface of each knob 310 is provided with anti-slip grooves. By providing the knobs 310 , the contact area of the top ends of the threaded rods 302 can be increased, making it easier to rotate the threaded rods 302 .

[0037] The inner wall sliding sleeve of the semi-solid sampling tube 2 is provided with a second baffle 308 , the upper surface of the second baffle 308 is rotatably connected to the bottom end of the corresponding threaded rod 302 , and the upper surface of the second baffle 308 is fixedly connected to two guide rods 309 .

[0038] The two guide rods 309 are slidably mounted on the inner wall of the connecting plate 301. The top of each guide rod 309 is fixedly connected to a limiting plate 311. By setting the limiting plate 311, the downward movement trajectory of the second baffle 308 can be limited to prevent the second baffle 308 from falling off from the inner wall of the connecting plate 301.

[0039] When the threaded rod 302 above the second baffle 308 is rotated, the second baffle 308 can be moved along the inner wall of the semi-solid sampling tube 2, and the second baffle 308 is moved to the specified position in conjunction with the opened second measuring range 8. Then, the semi-solid sampling tube 2 is slowly inserted into the jelly-like semi-solid food through the sampling head 5 at the bottom end of the semi-solid sampling tube 2. The jelly-like semi-solid food will contact the second baffle 308. At this time, it is no longer possible to continue sampling the jelly-like semi-solid food, and the quantitative sampling of the jelly-like semi-solid food is completed.

[0040] In summary, the device can perform quantitative sampling on semi-solid foods like jelly, as well as on liquid foods, thus meeting various sampling requirements and improving the practicability of the device.

[0041] Working principle: When it is necessary to take quantitative samples of liquid food, the position of the first baffle 303 can be adjusted by rotating the threaded rod 302 above the liquid sampling tube 1, and the first baffle 303 can be adjusted to the quantitative position in conjunction with the first measuring range 7, and then the sealing plug at the output end of the liquid suction port 4 is removed, and then the liquid suction port 4 is extended into the liquid, and the handle 306 is pulled upward, and the piston 304 can be moved upward through the two connecting rods 305, so that the liquid can be sucked into the liquid sampling tube 1 through the liquid suction port 4. When the upper surface of the piston 304 contacts the bottom surface of the first baffle 303, the preset sampling amount is reached, and the handle 306 can no longer be pulled upward, and then the sealing plug is blocked at the bottom end of the liquid suction port 4 to complete the liquid sampling. When quantitative sampling of a semi-solid food like jelly is required, the threaded rod 302 above the semi-solid sampling tube 2 can be rotated to change the position of the second baffle 308 in the semi-solid sampling tube 2, and the second baffle 308 can be adjusted to a preset position in conjunction with the second measuring range 8. Then, the semi-solid sampling tube 2 can be inserted into the semi-solid food like jelly through the sampling head 5 at the bottom end of the semi-solid sampling tube 2. The semi-solid food like jelly will enter the semi-solid sampling tube 2. When the upper surface of the semi-solid food like jelly contacts the bottom surface of the second baffle 308, the quantitative sampling of the semi-solid food like jelly is completed. This can meet sampling needs of different types and is more practical.

[0042] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
