Specific embodiments

[0023] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings.

[0024] Secondly, the present utility model will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of description, the sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present utility model here.

[0025] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0026] The present utility model provides a temperature measurement component for a PCR instrument. The support plate is installed at the lower end of the cover plate through the provided bolts. The temperature measurement probe is tightly installed at the lower end of the circuit board through the provided elastic member, tightening plate and the side plate on the side wall of the temperature measurement probe. Later, the support plate can be separated from the cover plate by removing the bolts, and then the temperature measurement probe can be directly removed manually, so that the temperature measurement probe can be disassembled and assembled quickly and conveniently.

[0027] Figures 1-3 Shown is a schematic structural diagram of an embodiment of a temperature measurement component of a PCR instrument of the present utility model. Please refer to Figures 1-3 In this embodiment, a temperature measurement component of a PCR instrument, its main part includes a support component 100, a temperature measurement structure 200 and a connection and tightening component 300.

[0028] The support component 100 includes a cover plate 110 and a support plate 120 arranged at the lower end of the cover plate 110. A slot 111 is formed inside the cover plate 110, and a placement groove 112 is formed at the lower end of the slot 111. The support plate 120 is installed in the placement groove 112 through bolts, and a plurality of through holes are formed inside the support plate 120. Preferably, in this embodiment, a sealing ring is arranged on the inner wall of the placement groove 112, and the material of the sealing ring is rubber. The sealing ring made of rubber arranged on the inner wall of the placement groove 112 plays a sealing role at the gap between the support plate 120 and the placement groove 112, preventing external dust from entering the interior through the gap, enhancing the sealing and dust-proof performance of the device. The bottom height of the bolt at the lower end of the support plate 120 is higher than the bottom height of the cover plate 110. The bolt at the lower end of the support plate 120 is higher than the bottom of the cover plate 110, which can ensure the stable closing of the cover plate 110 subsequently.

[0029] The temperature measurement structure 200 includes a circuit board 210 arranged in the slot 111 of the cover plate 110 and a plurality of temperature measurement probes 220 arranged at the lower end of the circuit board 210. The temperature measurement probes 220 are arranged in the through holes, and side plates 221 are fixed on the opposite outer walls of the temperature measurement probes 220.

[0030] The connection and tightening component 300 includes elastic members 310 vertically arranged on both sides of the upper end of the through holes of the support plate 120 and a tightening plate 320 fixed at the upper ends of the elastic members 310. The tightening plate 320 is located below the side plates 221. Preferably, in this embodiment, a telescopic rod 311 is arranged inside the elastic member 310, and both ends of the telescopic rod 311 are respectively connected to the tightening plate 320 and the support plate 120. The telescopic rod 311 arranged inside the elastic member 310 plays a limiting role on the elastic member 310, preventing the elastic member 310 from being distorted. A clamping groove is formed at the upper end of the tightening plate 320, and the side plates 221 are clamped in the clamping groove. The clamping groove formed at the upper end of the tightening plate 320 plays a limiting role on the side plates 221, preventing the side plates 221 from slipping off the upper end of the tightening plate 320.

[0031] Combined Figures 1-3, A temperature measurement component of a PCR instrument in this embodiment is used as follows: The operator separates the support plate 120 from the cover plate 110 by removing the bolts at the lower end of the support plate 120. Then, the operator can directly manually take out the temperature measurement probe 220 from the through hole of the support plate 120, so that the temperature measurement probe 220 can be disassembled and assembled quickly and conveniently. When replacing the new temperature measurement probe 220, the operator directly inserts the new temperature measurement probe 220 into the through hole of the support plate 120 and makes the side plate 221 on its relative side wall snap into the card slot of the top pressing plate 320. Then, the support plate 120 is placed in the placement groove 112 and fixed by bolts. At this time, the elastic member 310 located below the top pressing plate 320 is in a compressed state. Under the elastic action of the elastic member 310 itself, an upward pressing force is applied to the upper top pressing plate 320, thereby applying an upward pressing force to the side plate 221 and the temperature measurement probe 220, and further ensuring the tight connection between the temperature measurement probe 220 and the upper circuit board 210.

[0032] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
