Technical Field
[0001] The utility model relates to the technical field of cosmetics detection, in particular to a detection test tube and a fixing device which are easy to clean. Background Art
[0002] In cosmetic testing, using a cleaning machine to clean test tubes can ensure the cleanliness, disinfection effect and stability of the test tubes, meet the requirements of hygiene, accuracy and environmental protection, and ensure the reliability and accuracy of cosmetic testing results. Therefore, test tubes used for cosmetic testing should be cleaned using a cleaning machine.
[0003] Traditional test tubes are straight-tube designs, and may not have threaded openings or matching caps. In the process of cosmetic testing, if a test requires mixing with reagents, it is inconvenient to use.
[0004] During the cleaning process of a traditional test tube cleaning machine, the test tube is often placed directly on a test tube holder. The test tube holder is a support rod, and the test tube to be cleaned is placed on the outer side of the support rod for positioning. During such a test tube cleaning process, the test tube may not have an effective fixing device, causing the test tube to move or tilt during the cleaning process, affecting the cleaning effect and safety. In addition, since risks during the operation may not be taken into consideration, such as the risk of collision between the test tube and the support rod, the possibility of accidents during the cleaning operation is increased. Utility Model Content

[0047] like Figure 3-7 As shown, a fixing device is used in conjunction with the above-mentioned easy-to-clean test tube, comprising a bottom box 30, a test tube holder 40, and a pressing plate 50 that cooperates with the bottom box 30 to position the test tube body 10 on the test tube holder 40;
[0048] The bottom box 30 is fixed in the laboratory cleaning machine, or installed in the laboratory cleaning machine by pulling, so that the bottle cleaning machine can clean the inner and outer walls of the test tube body 10.
[0049] The test tube holder 40 includes a convex sleeve 41 with internal threads and four limit blocks 42 arranged in an annular manner and equidistantly on the outer side of the convex sleeve 41 . The four limit blocks 42 clamp the test tube body 10 and position it in the space surrounded by the four limit blocks 42 .
[0050] The convex sleeve 41 and the annularly arranged limit blocks 42 of the test tube holder 40 can accurately position the test tube body 10 on the test tube holder 40. The four limit blocks 42 clamp the test tube body 10 in the space, which can effectively prevent the test tube from moving or falling off during the cleaning process, thereby improving the stability and safety of cleaning. The use of the pressing plate 50 can conveniently remove and place the test tube body 10 from the bottom box 30 and the test tube holder 40, thereby improving the efficiency and convenience of cleaning the test tube body 10.
