Although the calibration device can reduce the complexity of instrument operation, the detection plates equipped on the existing PCR analyzers are often 24, 48, 96 wells, etc., but the number of sensors in the device is limited, with only 2 rows of 8-well temperature sensors. Therefore, it is only suitable for 16-well PCR analyzers and cannot be applied to different types of PCR plates, which greatly reduces the applicability of the calibration device; and there is no alarm prompt for whether the calibration data is out of tolerance, which is not conducive to the control of experimental risks. In terms of actual use, this problem is obviously a real problem that exists and is difficult to solve. Therefore, in order to solve this technical problem, the combination component 2 and the alarm component 3 are added to the application document.

It should be noted that the working principles of the analyzer body 1 and the temperature sensing rod 12 of the device can be found in the technical content disclosed in announcement number: CN212275110U.

More specifically:

As shown in Figure 1 to Figure 3;

In combination with the above, it also includes a combination assembly 2 mounted on the surface of the analyzer body 1;

The combined component 2 includes a measuring board 21 installed on the bottom surface of the analyzer body 1 and a measuring board 22 symmetrically arranged on the surface of the measuring board 21.

The measuring board 21 and the measuring board 22 are plugged into each other through the plug-in block 23 and the slot.

In this embodiment, the insert block 23 on the measuring plate 22 is inserted into the slot provided on the surface of the measuring plate 1 21 to expand the temperature sensing rod 12, thereby increasing the number of the temperature sensing rods 12, so that it can be applied to 96-well, 48-well and other PCR plates, thereby improving the overall adaptability.

Going further:

As shown in Figures 1 to 4;

In order to be able to install and disassemble the measuring plate 22, in an optional embodiment, a sleeve rod 24 is installed on the surface of the measuring plate 1 21, a fixing plate 25 is installed inside the sleeve rod 24, a connecting rod 26 is slidably connected in a through hole opened in the surface of the fixing plate 25, one end of the connecting rod 26 passes through the fixing plate 25 and the measuring plate 1 21 in sequence, and is inserted into the socket opened on the surface of the plug block 23.

In this embodiment, the connecting rod 26 in the sleeve rod 24 slides in the through hole opened on the surface of the fixing plate 25, which can fix the position of the insert block 23, thereby achieving the position installation of the measuring plate 22, and vice versa, it can be disassembled to prevent it from being out of position during use.

It should be noted that the sleeve rod 24 is connected to the measuring plate 21 ; the connecting rod 26 can be inserted into the insertion hole provided on the surface of the insert block 23 by adopting the connecting manner.

Going further:

As shown in Figure 3-Figure 4;

When limiting the position of the connecting rod 26 , in an optional embodiment, a limiting plate 27 is installed on the surface of the connecting rod 26 .

In this embodiment, the limiting plate 27 on the connecting rod 26 can limit the sliding position of the connecting rod 26 to prevent the connecting rod 26 from being separated from the sleeve rod 24.

Going further:

As shown in Figure 3-Figure 4;

For the convenience of operators, in an optional embodiment, a compression spring 28 is sleeved on the surface of the connecting rod 26 , one end of the compression spring 28 is connected to the limiting plate 27 , and the other end of the compression spring 28 is connected to the fixed plate 25 .

In this embodiment: when the connecting rod 26 is pulled, the limit plate 27 squeezes the compression spring 28. When the connecting rod 26 is released, the compression spring 28 is not squeezed and restores its shape, thereby driving the connecting rod 26 to be inserted into the insert block 23. The compression spring 28 can be used conveniently by the operator.

More specifically:

As shown in Figure 1;

In combination with the above content, it also includes an alarm component 3 installed on the surface of the analyzer body 1, the alarm component 3 includes a sensor 31 electrically connected to the bottom surfaces of the measuring board 1 21 and the measuring board 2 22, an alarm light 32 is installed on the surface of the analyzer body 1, the sensor 31 is electrically connected to the alarm light 32 through an electric wire, and the sensor 31 is connected to the temperature sensing rod 12.

In this embodiment, when the alarm light 32 lights up, the alarm speaker 33 sounds an alarm, thereby improving the alarm effect of the device.

The working principle and use process of the utility model are as follows: when the temperature sensing rod 12 is expanded, the connecting rod 26 is first pulled, and the connecting rod 26 slides on the fixed disk 25 on the surface of the sleeve rod 24. At this time, the limit disk 27 on the connecting rod 26 squeezes the compression spring 28, causing the compression spring 28 to deform, and then the plug block 23 on the surface of one side of the measuring plate 22 is inserted into the slot provided on the surface of the measuring plate 1 21. At this time, the connecting rod 26 is released. Since the compression spring 28 is not squeezed, it recovers its shape at this time, thereby driving the connecting rod 26 to be inserted into the jack provided on the surface of the plug block 23. When the temperature exceeds the tolerance, it is sensed by the sensor 31 on the bottom surface of the measuring plate 1 21 and the measuring plate 22. When the data is abnormal, the alarm light 32 lights up and the alarm horn 33 sounds an alarm, thereby reminding the operator.

Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
