[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] See also Figure 1-4 An assembled PCR plate includes a main body module 100 and a disassembly module 200. The main body module 100 includes a mounting plate 110. Both sides of the mounting plate 110 are fixedly connected with connecting strips 120. The disassembly module 200 is arranged between the mounting plate 110 and the two connecting strips 120. The disassembly module 200 includes multiple groups of locking components 210 respectively arranged on the top of the two connecting strips 120. A plurality of mounting slot components 220 are arranged on the top of the mounting plate 110. PCR plate components 230 are arranged in the plurality of mounting slot components 220. Each group of locking components 210 is respectively connected to one of the PCR plate components 230.

[0038] By setting the locking assembly 210, the PCR plate assembly 230 can be locked and limited. By setting the mounting slot assembly 220, the PCR plate assembly 230 can be easily installed. By setting the PCR plate assembly 230, fewer reagent tubes are set, which facilitates the adjustment of the number of reagent tubes in a smaller range.

[0039] The locking assembly 210 includes two fixing blocks 211 fixedly connected to the top of one of the connecting strips 120, a rotating rod 212 is rotatably connected between the two fixing blocks 211, a mounting plate 213 is fixedly connected to the surface of the rotating rod 212, the locking assembly 210 also includes two plastic semi-cylinders 214 fixedly connected to the bottom of the mounting plate 213, the bottoms of the two plastic semi-cylinders 214 are provided with a snap-in groove 215, the bottoms of the two plastic semi-cylinders 214 are fixedly connected with a plastic conical column 216, the locking assembly 210 also includes two circular grooves 217 respectively opened on opposite sides of the two plastic conical columns 216, and a spring 218 is arranged between the insides of the two circular grooves 217.

[0040] By pushing the two plastic conical columns 216 together, the spring 218 can be contracted, so that the two plastic conical columns 216 and the two plastic semi-cylinders 214 can be closed, thereby facilitating the two plastic conical columns 216 and the two plastic semi-cylinders 214 to withdraw from the first slot 222 and the second slot 232.

[0041] The mounting slot assembly 220 includes a through slot 221 opened at the top of the mounting plate 110, and a first slot 222 is opened at the top of the mounting plate 110 and at both ends of the through slot 221. The circle formed by the two plastic semi-cylinders 214 fitting together and the circle formed by the two plastic conical columns 216 fitting together are equal to the first slot 222, and the two plastic semi-cylinders 214 and the two plastic conical columns 216 are both located inside the first slot 222. The PCR plate assembly 230 includes a PCR plate body 231 movably connected to the top of the mounting plate 110, and a second slot 232 is opened at both ends of the PCR plate body 231. A plurality of reagent tube bodies 233 are arranged on the PCR plate body 231, and the circle formed by the two plastic semi-cylinders 214 fitting together and the circle formed by the two plastic conical columns 216 fitting together are equal to the second slot 232, and the two plastic semi-cylinders 214 and the two plastic conical columns 216 are both located inside the second slot 232.

[0042] The provision of the through slot 221 facilitates the extension of the reagent tube body 233 to the bottom of the mounting plate 110. The provision of the first slot 222 and the second slot 232 enables the two plastic semi-cylinders 214 and the two plastic conical columns 216 to be inserted into the first slot 222 and the second slot 232. The two plastic conical columns 216 can be propped open by the spring 218, so that the two plastic conical columns 216 can be clamped to the bottom of the first slot 222 through the clamping slot 215, thereby locking the PCR plate body 231.

[0043] The implementation principle of the embodiment of the present application is: when the PCR plate body 231 needs to be disassembled, first push the two plastic conical columns 216 together so that the spring 218 can shrink, thereby driving the two plastic semi-cylinders 214 to close, and then rotate the mounting plate 213, thereby driving the two plastic semi-cylinders 214 and the two plastic conical columns 216 to withdraw from the first slot 222 and the second slot 232, thereby releasing the lock on the PCR plate body 231, and then the PCR plate body 231 can be disassembled. Since there are fewer reagent tube bodies 233 arranged on one PCR plate body 231, the number of reagent tube bodies 233 can be adjusted to a smaller extent, thereby improving practicality.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
