The differences between multiple light sources and detectors affect the consistency of the test results, requiring offline equipment and resources. In addition, the precision and complexity of conventional equipment require complex parameter settings and professional testing personnel to operate, which limits the universality of its application and makes it difficult to achieve routine testing in public places and at home. For this reason, a convenient detection device has been introduced.

When only one group needs to be tested, the other groups of placement openings will also be in an open state. In the open state, dust and impurities may fall into them during the detection process, thereby causing trouble. In addition, when the existing portable detection devices are used to detect reagents, the horizontal state of the machine cannot be adjusted according to the inclination of the desktop. When the machine body is tested in an inclined state, it may cause errors in the measurement data. Therefore, a portable detection device based on fluorescent reagents is proposed to solve the above problems. Utility Model Content

[0033] Reference Figure 2-Figure 4 The shielding assembly 4 includes a moving block 41, and a shielding plate 44 is fixedly connected to the bottom end of the outer wall of the moving block 41. Four sets of guide grooves are opened on the surface of the body 1. The four sets of moving blocks 41 are slidably connected to the inner walls of the guide grooves of the body 1. The setting of the four sets of guide grooves of the body 1 enables the moving block 41 to drive the shielding plate 44 to move laterally on the inner wall of the body 1 during the movement, thereby closing or opening the detection placement port corresponding to the shielding plate 44. The shielding plate 44 is slidably connected to the inner wall of the body 1. The shielding plate 44 is used to The reagent detection placement port is covered to prevent the other groups from being exposed to the outside and easily falling impurities when one group needs to be tested. The inner wall of the moving block 41 is elastically connected to the limiting block 43 through a limiting spring 42. One end of the limiting spring 42 is fixedly connected to the inner wall of the moving block 41, and the other end of the limiting spring 42 is fixedly connected to the outer wall of the limiting block 43. The function of the limiting spring 42 is that the limiting block 43 can be automatically reset when it is squeezed and moved, and the outer wall of the limiting block 43 is slidably connected to the inner wall of the moving block 41.
[0034] Reference Figure 1 and Figure 5The bottom end of the outer wall of the machine body 1 is provided with an adjustment component 5, which includes a fixed column 51, and the fixed column 51 is provided with four groups. The four groups of fixed columns 51 are fixedly connected to the bottom end of the outer wall of the machine body 1, and the sliding column 52 is slidably connected to the inner wall of the fixed column 51. The sliding column 52 is lowered on the inner wall of the fixed column 51, so that the level of the four corners of the machine body 1 can be adjusted, so that the overall placement position of the machine body 1 is in a stable state. The inner wall of the sliding column 52 is elastically connected to a pressing block 54 through a return spring 53, and one end of the return spring 53 is fixedly connected to the outer wall of the pressing block 54 The bottom end of the slider 52 is fixedly connected to the other end of the return spring 53 on the inner wall of the sliding column 52. The function of the return spring 53 is to automatically reset the pressing block 54 by the elastic action of the return spring 53 without operating it when the pressing block 54 is moved. The pressing block 54 is slidably connected to the inner wall of the sliding column 52. The surface of the fixed column 51 is provided with a plurality of groups of empty grooves. The outer wall of the pressing block 54 contacts the inner wall of the empty groove. The two are in contact with each other, so that the sliding column 52 can be adjusted and fixed at multiple positions of the inner wall of the fixed column 51.
[0035] Working principle: When conducting the test, first place the body 1 on a surface such as a table. At this time, the left and right groups of spirit levels 3 on the surface of the body 1 can be used to observe whether the placement position of the body 1 is tilted. When one side is lower or higher, the corresponding group of fixed columns 51 can be grasped and the pressing block 54 can be pressed to move on the inner wall of the sliding column 52. When the pressing block 54 is separated from the empty slot at the current position of the fixed column 51, it will move on the inner wall of the sliding column 52 and squeeze the reset spring 53 and allow it to be elastically compressed. At this time, the sliding column 52 can be moved up and down on the inner wall of the fixed column 51 to adjust it according to the spirit level 3. After the adjustment is completed, the pressing block 54 can be released and it will be elastically acted upon by the reset spring 53 to restore it to its initial position, thereby plugging it into the empty slot at the current position of the fixed column 51 to fix the position of the sliding column 52 to prevent the body 1 from tilting, which can easily cause the reagent to tilt and cause errors in the test results.
[0036] At the same time, the moving block 41 can be directly pressed to drive the baffle plate 44 to move on the inner wall of the body 1, so that the reagent placement port of the body 1 currently blocked by the baffle plate 44 is opened, so that the reagent can be placed in the placement port. At the same time, when the moving block 41 is moving, the triangular surface of the limit block 43 on its inner wall will be disengaged from the limit groove 6 at the current position of the body 1, and squeezed by its inner wall, allowing it to move on the inner wall of the moving block 41 until the moving block 41 moves to the end, the limit block 43 will be elastically acted upon by the limit spring 42, restoring it to its initial position, so that it contacts the inner wall of the limit groove 6 at the current position of the body 1, thereby fixing the position of the baffle plate 44. At this time, the reagent can be placed on the inner wall of the placement port. By setting multiple groups of baffle plates 44, when only one group needs to be measured, the placement ports of other groups can be closed to prevent dust and impurities from falling into them.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
