Description

Technical Field

[0001] This utility model relates to the field of PCR analyzer technology, and in particular to a screen for a real-time fluorescence PCR analyzer. Background Technology

[0002] Traditional PCR analyzers have a screen fixed directly to the main body, resulting in a fixed display angle and immobility. To accommodate the needs of different users, current PCR analyzers employ rotating screens, allowing for adjustable display angles by rotating the screen panel to suit different individuals.

[0003] The rotating screen offers high operability, but its internal installation requires a more stable casing structure. Only with a stable casing can the rotation be adapted to the needs of different users. Furthermore, when not in use, the screen needs to be secured to the top shell of the PCR analyzer and kept horizontal. Because the screen is rotated during normal use, the current screen structure suffers from some instability. Over time and with frequent rotation, this can occasionally lead to loosening of the wiring, affecting normal operation. Utility Model Content

[0004] The purpose of this invention is to provide a screen for a real-time fluorescence PCR analyzer to solve the problems encountered in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A screen for a real-time fluorescence PCR analyzer includes a display component, a front shell, and a rear cover. A positioning block is provided on one side of the display component, and a positioning groove that mates with the positioning block is provided on one side of the inner frame of the front shell. The front shell and the rear cover fix the display component inside. An upper shaft shell is provided on the top of the front shell, and a lower shaft shell is provided on the top of the rear cover. The upper shaft shell and the lower shaft shell are fastened together to form a rotating shaft cavity. A rotating component is rotatably connected to one side of the rotating shaft cavity, and a support block is rotatably connected to the other side of the rotating shaft cavity.

[0007] In the above solution, the end of the positioning block has a hook-shaped structure, and the display component has a wiring groove on the side away from the positioning block. Additionally, the display component includes a display screen and a touch surface attached to the outside of the display screen, and the display screen matches the inner frame of the front housing.

[0008] In the above design, the upper shaft housing has a mounting hole on the side near the rotating assembly, and a shaft groove on the side near the support block. Additionally, the inner perimeter of the front housing has threaded seats, and the bottom inner sides of the front housing have limiting grooves on both sides, with soft gaskets installed in the limiting grooves.

[0009] In the above scheme, the inner perimeter of the rear cover is provided with threaded posts that cooperate with the threaded seat, and the inner side of the rear cover is provided with ribs.

[0010] In the above scheme, the rotating assembly includes a damping seat and a damping shaft. One end of the damping shaft is inserted into the damping seat, which is mounted on the upper housing. The other end of the damping shaft is inserted into the shaft cavity and rotatably connected to it. The support block includes a base and a cover plate. The base and cover plate are fastened together to form a rotating cylinder, which is rotatably connected to the shaft cavity. The top of the cover plate has a planar structure.

[0011] Compared with existing technologies, the advantages of this invention are as follows: the cooperation of the positioning block and the positioning groove ensures accurate installation and positioning, contributing to structural stability and preventing wobbling. Screws secure the front and rear covers to the display components internally, ensuring a stable display. The rotating component, after installation with the upper housing, facilitates the rotation of the entire screen. The support block supports the rotation and, when the screen rotates to the upper plane, supports the screen panel, thus stabilizing the screen during rotation. Therefore, the structure of this screen is more stable than existing technologies, preventing loose wiring and providing stable display functionality during screen rotation.
