Description

Technical Field

[0001] The utility model belongs to the technical field of food detection, and in particular relates to a sample rack for food detection. Background Art

[0002] The development of analytical chemistry has provided accurate and reliable analysis methods for food safety inspection. With the rapid development of science and technology, food inspection technology has been able to achieve an accuracy of one part per million or even one part per billion. The indicators of food inspection mainly include general component analysis, trace element analysis, pesticide residue analysis, veterinary drug residue analysis, mycotoxin analysis, food additive analysis and analysis of other harmful substances. According to the characteristics of the inspected items, the inspection of each indicator corresponds to the corresponding inspection method. In addition to the traditional conventional analysis methods, instrumental analysis methods have gradually become the main means of food hygiene inspection. When the instrument analyzes food substances, it is necessary to use a sample rack to place the food sample can. The current sample rack lacks a limit on the placement of the food sample can, resulting in insufficient stability in the placement of the food sample can. In the process of taking and placing the food sample can that needs to be used, it is easy to cause shaking to other food sample cans, causing the food sample can to fall over. The use stability of the sample rack is insufficient, so the inventor proposes a sample rack for food testing. Utility Model Content

Detailed Embodiment

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] This detailed embodiment is a sample rack for food detection, and its structural schematic diagram is asFigure 1 As shown, it includes a storage rack 1, a limiting mechanism 7, a sample storage plate 3, and a placement groove 4. The sample storage plate 3 is slidably arranged in the storage rack 1. Multiple groups of sample storage plates 3 are arranged in parallel in the storage rack 1. There are sliding grooves 2 on the inner wall of the storage rack 1 that are adapted for the sliding installation of the sample storage plate 3.

[0024] Referring to Figure 2 , multiple groups of placement grooves 4 are arranged in an array on the upper surface of the sample storage plate 3. A knob 6 is arranged on the upper surface of the sample storage plate 3 beside the placement groove 4. Clamping blocks 5 are symmetrically arranged on the two inner sidewalls of the placement groove 4. The clamping blocks 5 slide from the inside of the sample storage plate 3 towards the inside of the placement groove 4. The bottom of the knob 6 penetrates into the sample storage plate 3 and is fixedly connected to a driving bevel gear 11. The driving bevel gear 11 and the knob 6 are concentrically distributed. A driven bevel gear 10 is arranged below the driving bevel gear 11. The driven bevel gear 10 and the driving bevel gear 11 are vertically distributed and meshed with each other. A driving shaft 12 is fixedly penetrated through the center of the driven bevel gear 10. The driving shaft 12 rotates synchronously with the driven bevel gear 10. Screw rods 9 are respectively fixedly connected to both ends of the driving shaft 12, and the screw threads at both ends of the screw rods 9 are distributed oppositely. A driving rod 8 is threadedly connected to the outside of the screw rod 9. The driving rod 8 has a threaded hole. The driving rod 8 and the driving shaft 12 are vertically distributed. One end of the driving rod 8 away from the screw rod 9 is fixedly connected to the clamping block 5.

[0025] Referring to Figure 1 , Figure 3 , Figure 4 , the limiting mechanism 7 is arranged on the side wall of the storage rack 1. Multiple groups of limiting mechanisms 7 are provided and respectively correspond to multiple groups of sample storage plates 3. The limiting mechanism 7 includes a fixed tube 14, a rotating head 16, and a limiting bolt 15. The fixed tube 14 is fixedly installed on the outer wall of the storage rack 1. The limiting bolt 15 is threaded through the fixed tube 14. A limiting hole 13 is opened on the side wall of the sample storage plate 3. The limiting bolt 15 is adaptively inserted into the limiting hole 13. One end of the limiting bolt 15 away from the limiting hole 13 is fixedly connected to the rotating head 16.

[0026] Working principle: When in use, first slide and install multiple groups of sample storage plates 3 along the storage rack 1 respectively. After sliding the sample storage plate 3 out of the storage rack 1, place the sample storage cans for food detection in the placement groove 4. Then rotate the adjacent knob 6. When the knob 6 rotates, it drives the driving bevel gear 11 to rotate. The driving bevel gear 11 and the driven bevel gear 10 are vertically distributed and meshed with each other. The driven bevel gear 10 drives the driving shaft 12 to rotate synchronously. The screw rods 9 at both ends of the rotating shaft of the driving shaft 12 then rotate. After the screw rods 9 rotate, they drive the driving rod 8 to move. The driving rod 8 is threadedly connected to the screw rod 9. Thus, the driving rod 8 can drive the clamping block 5 to slide from the inside of the sample storage plate 3 towards the inside of the placement groove 4. The clamping blocks 5 on the two inner sidewalls of the placement groove 4 move synchronously to clamp the sample storage cans inside the placement groove 4, which can effectively improve the stability of the food sample storage cans;

[0027] After the food sample storage cans on the sample storage plate 3 are clamped, the sample storage plate 3 can be slid into the interior of the storage rack 1. After the sample storage plate 3 is completely slid in, the rotating head 16 can be rotated, and the rotating head 16 drives the limit bolt 15 to be screwed into the interior of the fixed pipe 14 until the limit bolt 15 is inserted into the limit hole 13 on the side wall of the sample storage plate 3. The sample storage plate 3 can be stably arranged in the storage rack 1. Even during transportation of the rack, the food sample storage cans can have strong stability and will not slide and fall off. When the sample storage plate 3 is pulled out, the sample storage cans clamped inside it will not shake either. And during the process of taking the sample storage cans, other accidentally touched sample storage cans also have strong stability.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
