Description

Technical Field

[0001] The utility model belongs to the technical field of milk powder detection, in particular to a reagent kit for detecting vitamin A in milk powder. Background Art

[0002] When testing milk powder, especially when testing vitamin A in milk powder, a test kit is often needed, and a test tube containing the reagent is placed in the test kit. The test kit is usually set as a structure with an upper opening, and a box cover is set at the upper opening. In order to be able to take the test reagents in batches, a test tube rack is set in the box body, and multiple test tubes are placed on the test tube rack. By taking out the test tube rack at a time, multiple test tubes can be taken out at the same time. Although this structure can improve the efficiency of taking the test reagents, in the process of manually pulling the test tube rack upwards, especially in order to ensure the stability of the test tube rack in the test kit, the test tube rack is installed tightly, and the force may be uneven when pulling it upwards, which can easily cause the test tube to move and the reagent in the test tube to shake significantly, affecting the safety of the test.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] As shown in the figure, a kit for detecting vitamin A in milk powder includes a box body 1, the front end of the box body 1 is opened, and a box cover 4 is connected to the front end opening of the box body 1, and a test tube rack 2 is movably inserted in the depth direction inside the box body 1, and the test tube rack 2 includes an upper side plate 201 and a lower side plate 202 located below the upper side plate 201, and the upper side plate 201 and the lower side plate 202 are fixed together by multiple connecting rods 203, and a plurality of limiting holes 205 are evenly opened on the upper side plate 201, and limiting grooves 206 are recessed downwards at the corresponding limiting holes 205 on the lower side plate 202, and a plurality of support blocks 207 with bottoms lower than the bottoms of the limiting grooves 206 are evenly provided at the bottom of the lower side plate 202. In this embodiment, the front opening of the box body 1 is provided so that the test tube rack 2 can be moved horizontally from the front opening of the box body 1, ensuring that the test tubes placed on the test tube rack 2 are more stable during the process of being moved out of the box body 1 or into the box body 1, and the test tube rack 2 is provided with a structure of an upper side plate 201 and a lower side plate 202, which are fixed together by connecting rods 203 at the four corners, so that the test tubes can be placed more safely, and at the same time, the two connecting rods 203 near the front opening of the box body 1 also serve as handrails, and the operator can hold the connecting rods 203 and move the test tube rack 2 horizontally, so that the test tube rack 2 can be inserted into the box body 1 or pulled out from the box body 1; in addition, a plurality of support blocks 207 with bottoms lower than the bottoms of the limiting grooves 206 are provided at the bottom of the lower side plate 202, so that when the test tube rack 2 is taken out of the box body 1, it can be stably placed on the operating table.

[0024] The openings of the limiting grooves 206 are all set to chamfer structures, which increase the size of the openings of the limiting grooves 206 and make it easier to insert the bottom of the test tube, while also meeting the needs of test tubes of different sizes; the bottom of the limiting grooves 206 is set to a downwardly concave spherical structure, which better fits the bottom structure of the test tube, making the test tube more stable on the test tube rack 2.

[0025] Limiting strips 101 are fixedly connected to the upper and lower surfaces of the upper and lower plates 201 and 202 on the left and right side walls inside the box body 1, and the left and right edges of the upper and lower plates 201 and 202 are respectively inserted between the corresponding two limiting strips 101.

[0026] Arc-shaped auxiliary strips 204 are fixedly connected to the left and right edges of the upper and lower surfaces of the upper side plate 201 and the lower side plate 202, and an arc-shaped through groove 102 is provided on the inner side of each limiting strip 101 corresponding to the corresponding auxiliary strip 204, and the auxiliary strip 204 is slidably inserted in the corresponding through groove 102. In this embodiment, by providing the arc-shaped auxiliary strips 204 and the corresponding through grooves 102, the friction force in the pushing and pulling process is effectively reduced, so that when the test tube rack 2 is pushed and pulled, the movement is smoother and more secure.

[0027] A magnetic strip is provided at the inner edge of the box cover 4, and a fixing strip that is magnetically attracted to the corresponding magnetic strip is provided at the front end of the box body 1 corresponding to the magnetic strip. In this embodiment, the fixing strip is made of iron and is fixed by the magnetic strip.

Guide posts are fixed outwardly at the upper ends of the left and right sides of the box cover 4, and the guide posts are embedded in the corresponding guide grooves 301 and can slide along the guide grooves 301. In this embodiment, the box cover 4 slides through the cooperation of the guide posts on both sides and the guide grooves 301, and can be moved to the top of the box body 1 when the opening of the box body 1 is moved away, which saves space, does not affect the operator's operation of the test tube rack 2 at the opening of the box body 1, and prevents the box cover 4 from accidentally falling off.

[0029] A handle 401 is provided on the outside of the box cover 4 to facilitate moving the box cover 4 .

[0030] The working process of this embodiment is as follows:

[0031] When taking out the test tube rack 2, pull the handle 401 to flip the box cover 4 upwards, until the box cover 4 is flipped to a horizontal state, and then push the box cover 4 backwards to move the box cover 4 backwards along the guide groove 301, until the box cover 4 is finally placed on the upper side of the box body 1; then pull out the test tube rack 2 and place it on the operating table, the operator places the test tubes containing the solution on the test tube rack 2 in turn, and then inserts the upper side plate 201 and the lower side plate 202 of the test tube rack 2 between the corresponding limiting strips 101, and moves it inwards into the box body 1, and finally moves the box cover 4 forward and flips it downwards, so that the magnetic strip on the box cover 4 is magnetically fixed to the fixing strip on the box body 1.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
