TECHNICAL FIELD

[0001] The utility model relates to PCR analysis appearance technical field especially relates to a real -time fluorescent PCR analysis appearance's lower shell subassembly. BACKGROUND

[0002] In the field of molecular biology, polymerase chain reaction technology (Polymerase Chain Reaction, referred to as PCR) is a commonly used experimental technique, and its basic principle is similar to the natural replication process of DNA, which is a method for in vitro enzyme synthesis of specific DNA fragments, and its specificity depends on the oligonucleotide primer complementary to the two ends of the target sequence. The instrument for realizing real-time fluorescent PCR analysis technology is called real-time fluorescent PCR analyzer, which is essentially a temperature control device that can accurately control the denaturation temperature, annealing temperature and extension temperature.

Detailed Implementation

[0019] To make the technical means, creative features, objectives, and effects of this utility model readily understandable, the utility model will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 2 As shown, a lower shell assembly of a real-time fluorescence PCR analyzer includes a lower shell 1 and an LED strip 2. The lower shell 1 is the bottom structure of the real-time fluorescence PCR analyzer. The wiring terminals of the LED strip 2 in the lower shell 1 are connected to the power supply inside the real-time fluorescence PCR analyzer. Several LED beads are evenly arranged on the LED strip 2, which can be powered on and lit up when the power is turned on.

[0023] The lower shell 1 has a Z-shaped structure. A light strip groove 11 is provided on the front side wall of the lower shell 1. The light strip groove 11 is horizontally set and its length is 2 / 3 to 4 / 5 of the length of the front side wall of the lower shell 1. Therefore, the light strip groove 11 is relatively long so that it is convenient for medical staff to see when the light is on.

[0024] Support columns 12 are provided at both ends of the inner side of the LED strip groove 11. A light-diffusing plate 21 is provided on the outer side of the light-emitting surface of the LED strip 2 to disperse the light emitted by the LED beads. The two sides of the light-diffusing plate 21 are inserted into the support columns 12, and the outer surface of the light-diffusing plate 21 protrudes from the outer side of the LED strip groove 11. By emitting light through the LED strip 2 and the light-diffusing plate 21, the entire LED strip groove 11 is illuminated. Because the LED strip groove 11 is relatively long and has a large brightness range, it can better facilitate medical personnel to visually obtain the technical effect of whether the PCR analyzer is turned on or running.

[0025] Please refer to the following when implementing: Figure 5The outer surface of the light diffuser 21 is provided with a raised strip 22. The cross-section of the raised strip 22 is semi-circular, and the length of the raised strip 22 is the same as the length of the lamp strip groove 11, so as to better match the two. As a preferred embodiment, the light diffuser 21 and the lamp strip 2 are respectively provided with insertion holes 23 on both sides. The insertion holes 23 match the support column 12. The support column 12 plays a positioning role. After the light diffuser 21 and the lamp strip 2 are inserted into the support column 12, the lamp strip 2 and the light diffuser 21 are fixed on the support column 12 with AB glue.

[0026] Specifically, please refer to Figure 3 and Figure 4 The lower shell 1 includes a liner 101, a side plate 102, and a bottom plate 103. The liner 101 and the bottom plate 103 are horizontally arranged, and the side plate 102 is vertically arranged. The top of the side plate 102 is connected to the liner 101, and the bottom of the side plate 102 is connected to the bottom plate 103. The liner 101, the side plate 102, and the bottom plate 103 are integrally connected and form a Z-shaped structure. Therefore, the three components form a right-angled Z-shaped structure after being connected.

[0027] Furthermore, in terms of structure, a retaining plate 14 is installed on the inner side of the liner 101 and the side plate 102. The retaining plate 14 has a right-angle structure. A stiffening plate 15 is provided on the inner side of the bottom plate 103. The stiffening plate 15 has a square frame structure. Both the retaining plate 14 and the stiffening plate 15 play a role in strengthening the support of the lower shell 1, providing a foundation for the stable installation of other components of the PCR analyzer. The liner 101 has at least two through holes 13. The four ends of the inner side of the bottom plate 103 have countersunk nuts 19. The front mounting holes 13 can be directly screwed to the upper shell for fixation. The nuts 19 at the bottom are screwed in from the inside to fix other components. The countersunk holes are used because the bottom is also equipped with feet 4. This installation does not damage the original installation structure of the feet 4.

[0028] Furthermore, regarding the installation of other auxiliary components, the top inner side of the base plate 103 is provided with a limiting groove 16 for installing the fan module 3, and the bottom surface of the limiting groove 16 has heat dissipation holes 17. There are two limiting grooves 16 for installing two fan modules 3, providing heat dissipation for the two reaction chambers of the PCR analyzer during operation. The bottom outer sides of the base plate 103 are provided with positioning grooves 18 for installing the feet 4. The positioning grooves 18 have a countersunk structure, allowing direct fixation with AB glue when installing the feet 4. AB glue is a two-component epoxy resin adhesive with high transparency, high bonding strength, and environmental friendliness and non-toxicity. The countersunk structure allows for better concentration of the glue on the bonding surface and the surrounding surfaces of the positioning grooves 18, resulting in a stronger bond.

[0029] When the real-time fluorescence PCR analyzer is turned on, the bright light from the breathing light diffuser 2 and the transparent light strip 3 reminds the user that the real-time fluorescence PCR analyzer has been turned on and provides the user with some illumination.

[0030] Compared to traditional PCR equipment, this real-time fluorescence PCR analyzer can visually remind medical staff that the PCR analyzer is turned on and running. Because the light strip 2 is relatively long, the brightness range is large, and it can also provide a certain lighting effect for the user.

[0031] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
