Description

Technical Field

[0001] This utility model relates to the field of base technology, and in particular to a PCR analyzer base structure. Background Technology

[0002] PCR, short for Polymerase Chain Reaction, is a method for the in vitro enzymatic synthesis of specific DNA fragments. It consists of a cycle of reactions including high-temperature denaturation, low-temperature annealing (renaturation), and appropriate-temperature extension, which are repeated cyclically to rapidly amplify the target DNA. It is characterized by high specificity, high sensitivity, ease of operation, and time-saving. It can be used not only for basic research such as gene isolation, cloning, and nucleic acid sequence analysis, but also for disease diagnosis or any application involving DNA or RNA. Current PCR analyzers are typically equipped with a base, which consists of four feet for support. However, the height of these feet varies, leading to a closer distance between the bottom of the analyzer and the work surface. During prolonged operation, the heat generated at the bottom of the PCR analyzer is difficult to dissipate quickly, potentially affecting internal electrical components. Furthermore, the feet on the bottom of current PCR analyzers are not easily adjustable to a suitable height for different work surfaces. Utility Model Content

[0003] This invention provides a PCR analyzer base structure, which solves the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A PCR analyzer base structure includes a PCR analyzer body, wherein a base is provided at the bottom end of the PCR analyzer body;

[0006] The base includes a circular shell, and a cooling fan is installed inside the shell. Four support rods are arranged equidistantly in a ring on the surface of the shell.

[0007] The bottom end of the support rod has a groove, and a screw is rotatably connected inside the groove. The screw passes through the support rod and is connected to a knob. Moving blocks are threaded to both sides of the surface of the screw. Baffles are symmetrically arranged at the bottom of the moving blocks. A movable shaft is connected between the two baffles, and a support bar is connected to the surface of the movable shaft. A pad is connected to the bottom of the support bar through the movable shaft.

[0008] As a further description of the above technical solution:

[0009] The movable block is slidably connected to the inner wall of the groove.

[0010] As a further description of the above technical solution:

[0011] The threads on both sides of the screw surface are arranged in opposite directions.

[0012] As a further description of the above technical solution:

[0013] A bracket is provided on the outer side of the top end of the support rod, and a bolt is threaded to the bottom end of the bracket.

[0014] As a further description of the above technical solution:

[0015] The height of the bracket must be greater than the length of the bolt.

[0016] As a further description of the above technical solution:

[0017] A through groove is provided on one side of the inner wall of the groove, and scale lines are provided on the surface of the through groove.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] In this invention, a cooling fan is installed on the base to dissipate heat from the bottom of the PCR analyzer, preventing the bottom from being too close to the workbench during long-term operation and making it difficult to dissipate heat in a short time. At the same time, by rotating the screw, the moving block can move the support bar and the pad, so as to adjust the overall height of the base. This allows the overall height of the PCR analyzer to be adjusted according to the height of different workbench surfaces, improving the convenience and comfort of operation. It also allows the bottom of the cooling fan to be moved away from the workbench for better heat dissipation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1-4 A PCR analyzer base structure includes a PCR analyzer body 1, with a base at the bottom of the body 1. The base includes a circular shell 2, with a cooling fan 3 installed inside the shell 2. Four support rods 4 are equidistantly arranged in a ring on the surface of the shell 2. A groove 5 is formed at the bottom of each support rod 4, and a screw 6 is rotatably connected inside the groove 5. The screw 6 passes through the support rod 4 and is connected to a knob. Moving blocks 7 are threaded onto both sides of the screw 6. Baffles are symmetrically arranged at the bottom of each moving block 7. A movable shaft connects the two baffles, and a support bar 8 is connected to the surface of the movable shaft. A pad 9 is connected to the bottom of the support bar 8 via the movable shaft. During use... When adjusting the height of the PCR analyzer body 1, rotating the screw 6 causes the movable blocks 7 on both sides of its surface to move the support bars 8, thus lifting the pads 9 at the bottom of the two support bars 8. By observing the distance the movable blocks 7 move, the remaining three movable blocks 7 can be moved to the specified distance, thereby adjusting the PCR analyzer body 1 to a suitable height for use. At the same time, the switch can be turned on to activate the cooling fan 3, which dissipates heat from the bottom of the PCR analyzer body 1. The cooling fan 3 is externally powered and has a switch. The connection between the support bars 8 and the pads 9 via the movable shaft is the same as the connection between the movable blocks 7 and the support bars 8.

[0028] Furthermore, the movable block 7 and the inner wall of the groove 5 are slidably connected, which is to facilitate the movable block 7, which is threaded on its surface, to drive the support bar 8 to move within the groove 5 when the screw 6 rotates.

[0029] Furthermore, the threads on both sides of the screw 6 surface are arranged in opposite directions, which is to facilitate the simultaneous movement of the moving blocks 7 on both sides of the screw 6 surface towards each other or away from each other when the screw 6 rotates.

[0030] Furthermore, a bracket 10 is provided on the outer side of the top of the support rod 4, and a bolt 11 is threadedly connected to the bottom of the bracket 10. The bolt 11 facilitates the installation and disassembly of the PCR analyzer body 1 and the base. Figure 2 As shown, the bracket 10 includes two support columns disposed at the top of the support rod 4, and the top of the support column is provided with a partition plate, and the bolt 11 is threadedly connected to the partition plate.

[0031] Furthermore, the height of the bracket 10 should be greater than the length of the bolt 11, so that the bolt 11 can be removed from the bottom of the PCR analyzer body 1, and at the same time, the cooling fan 3 should be a certain distance from the bottom of the PCR analyzer body 1 to facilitate heat dissipation.

[0032] Furthermore, a through groove 12 is provided on one side of the inner wall of the groove 5, and a scale line is provided on the surface of the through groove 12. The through groove 12 and the scale line are for easy observation of the distance moved by the moving block 7, so that all four moving blocks 7 can be moved to the designated position. The through groove 12 and the scale line are distributed on the surface of each support rod 4.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
