Description

Technical Field

[0001] The utility model belongs to the field of milk powder production detection, in particular to a milk powder detection kit. Background Art

[0002] After milk powder is produced, it must be tested. The nutritional content testing includes the testing of protein, fat, carbohydrates, vitamins and minerals; the harmful substance testing includes the testing of heavy metals (including mercury), pesticide residues, pathogenic bacteria, melamine, etc.; the microbial quality testing includes the testing of total colony count, coliform group, Salmonella, Staphylococcus aureus, etc. All of the above tests require the extraction of milk powder samples and placing the milk powder samples in reagent tubes.

[0003] In order to improve the efficiency of milk powder sample detection, some test kits containing reagent tubes are provided with a transport structure for transporting multiple reagent tubes at the same time. For example, a milk powder vitamin A detection kit disclosed in application No. 202322133258.6 includes a box body and a box cover. A clamping and transfer mechanism is provided in the box body. The clamping and transfer mechanism includes a main board and a sub-board. The main board is slidably arranged in the box body. The main board is provided with a plurality of first limiting holes. The sub-board is slidably arranged in the cavity of the main board, and a telescopic rod is provided on one side of the sub-board. A spring is sleeved on the outside of the telescopic rod. The sub-board is provided with a matching groove corresponding to the first limiting hole. Under the action of the spring, the matching groove and the first limiting hole on the main board cooperate to clamp and fix the multiple reagent tubes.

[0004] This solution uses a clamping and transfer mechanism to clamp and fix multiple reagent tubes, and to transport multiple reagent tubes at the same time. However, this technical solution has shortcomings, such as the matching groove is a circular groove, and the matching groove clamps and fixes the reagent tube inserted in the first limit hole under the action of the spring. Since there is no deformation control structure corresponding to the spring, each reagent tube needs to overcome the elastic force of the spring when inserted, which makes it inconvenient to load the reagent tube. At the same time, in this technical solution, only one handle is set on the main board. When the handle is used to transport the main board, the main board is easy to shake and deflect, and the stable transportation of the reagent tube cannot be guaranteed. During transportation, the inspector needs to operate carefully, which makes the operation inconvenient. Utility Model Content

When the magnetic steel 32 is used, the magnetic pole polarity of the magnetic steel 32 and the polarity of the magnetic ring 2 are set oppositely to ensure that the magnetic steel 32 and the magnetic ring 2 can be attracted. A pressing block 8 is provided in the box cover 3. After the box cover 3 and the box body 1 are buckled, the pressing block 8 can press and fix the reagent tube clamping and transporting mechanism 5 set in the box body 1 to ensure that the reagent tube clamping and transporting mechanism 5 is stable in the box body 1.

[0037] The structure of the box body 1 is as follows Figure 3 , Figure 4 As shown, the bottom surface of the box body 1 is provided with a limiting blind hole 102 facing the insertion hole 502, and one set of the facing side walls of the box body 1 is provided with two positioning grooves 101 in the vertical direction, the upper end of the positioning groove 101 is open to form a socket on the top surface of the box body 1, and the lower end of the positioning groove 101 is closed to form a step surface 103. A reagent tube clamping and transporting mechanism 5 for fixing the reagent tube is provided in the box body 1.

[0038] Reagent tube clamping and transporting mechanism 5 Figure 5 , Figure 6 and Figure 7 As shown, it includes a main board 501 and a sub-board 508. The main board 501 has a slider 504 protruding from the side thereof and matching the positioning groove 101. The slider 504 is slidably arranged in the positioning groove 101 and supported and limited by the step surface 103. Figure 3As shown, a certain distance is left between the reagent tube clamping and transporting mechanism 5 and the bottom of the box body 1. Two handles 505 are symmetrically rotated on the top surface of the main board 501 through the base 512. The setting of the two handles 505 can improve the transport stability of the reagent tube clamping and transporting mechanism 5 and prevent deflection and shaking. The main board 501 is penetrated by a plurality of jacks 502 for inserting reagent tubes. A cavity is provided in the main board 501, and the jack 502 passes through the cavity. An opening connected to the cavity is provided on one side of the main board 501. This embodiment is described by taking the opening being provided on the left side of the main board as an example. A sub-plate 508 is provided in the cavity of the main board 501 for sliding in the left-right direction, and a plurality of springs 510 are provided between the right side wall of the sub-plate 508 and the right side wall of the cavity. A cam 507 is provided at the left end of the cavity for rotation, and a knob 506 matching the cam 507 is provided on the top surface of the main board 501. The knob 506 is rotated to drive the cam 507 to rotate, so that the sub-plate 508 moves in the left-right direction in the cavity of the main board 501, and the proximal and distal ends of the cam press against the sub-plate 508, so that the spring 510 has two compression states, and the sub-plate 508 has two position states, and the spring 510 is in a compressed state in both position states.

[0039] The structure of the sub-board 508 is as follows Figure 8 As shown, the sub-plate is provided with a clamping groove 509 corresponding to the insertion hole 502, and the opening of the clamping groove 509 is away from the spring 510, that is, it is set to the left.

[0040] In the present invention, the clamping groove 509 is a V-shaped groove structure with an angle of 60-90 degrees. This structure clamps the reagent tube through three points, such as Fig. 9 As shown, the reagent tube clamping and fixing stability is improved, and at the same time, the mechanism improves the applicability of the utility model. The same type of reagent tube 6 is clamped in the inspection of the same batch, and different types of reagent tubes 6 can be clamped for the inspection of different batches of milk powder.

When it is necessary to transport the test tube, open the box cover 3, use two handles 505 to lift the test tube clamping and transporting mechanism 5, so that the test tube clamping and transporting mechanism 5 slides out of the positioning groove 101, and then move the test tube clamping and transporting mechanism 5 by hand with the handles, so as to realize the simultaneous transportation of multiple test tubes.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
