[0046] like Figure 1 and Figure 2 As shown, the utility model provides a screen flipping device and a sample analyzer, the sample analyzer includes a screen flipping device, the screen flipping device includes a housing 10, a screen assembly 20 and a first hinge structure 30, the screen assembly 20 is rotatably arranged on the housing 10 through the first hinge structure 30. The first hinge structure 30 includes a fixed mounting member 31 and a rotating mounting member 32, the fixed mounting member 31 is arranged on the housing 10, the rotating mounting member 32 is arranged on the screen assembly 20, and the fixed mounting member 31 and the rotating mounting member 32 are rotatably connected through a first rotating shaft 33; the first hinge structure 30 also includes a first damping member to provide a damping force to position the screen assembly 20 after flipping.

[0047] By providing a flippable screen assembly 20, it is convenient to adjust the angle of the screen assembly 20 according to the height of the user, thereby providing a better screen visual effect for users of different heights, improving the comfort of use, and avoiding visual discomfort; by providing a first hinge structure 30 with a first damping member, when the screen assembly 20 is flipped, the rotating mounting member 32 on the screen assembly 20 is driven to rotate, and the friction force provided by the first damping member is utilized to enable the screen assembly 20 to maintain the flipping angle for positioning after being flipped, thereby effectively avoiding the problem of the screen assembly 20 rotating after being flipped, and ensuring that the screen assembly 20 can meet the normal operation requirements after being flipped.

[0048] In this embodiment, the screen assembly 20 is an integrated screen; the first hinge structure 30 is located at the top of the back of the screen assembly 20. In other embodiments, the first hinge structure 30 can also be arranged in the middle of the screen assembly 20.

[0049] Specifically, the fixed mounting member 31 and the rotating mounting member 32 are both sheet-like mounting members, which include a main board and a connecting portion. The two connecting portions are arranged on the main board and are respectively located on both sides of the main board, and the plane where the connecting portions are located is perpendicular to the plane where the main board is located; a first mounting hole is provided in the middle of the main board, and the first mounting hole is used for bolts or screws to pass through to fix the mounting member on the shell 10 or the screen assembly 20; the connecting portion extends along the side edge of the main board and protrudes from the main board, and a first through-hole is provided on the connecting portion to install the first rotating shaft 33.

[0051] Furthermore, the first rotating shaft 33 is a screw rod, which is passed through the rotating mounting member 32, the fixed mounting member 31 and the first damping member and is locked by a nut. By setting the screw rod and the nut to cooperate, the rotating mounting member 32, the fixed mounting member 31 and the first damping member are pressed together to adjust the magnitude of the friction force.

[0052] In this embodiment, the first damping member includes a first friction plate 34 and a first gasket 35. A plurality of first friction plates 34 are provided, and the plurality of first friction plates 34 are sleeved on the first rotating shaft 33; the first friction plate 34 is fixedly connected to the first rotating shaft 33, and the first gasket 35 is rotatably connected to the first rotating shaft 33; a first friction plate 34 is fitted between the connecting portion of the rotating mounting member 32 and the connecting portion of the fixed mounting member 31, and a first friction plate 34, a plurality of first gaskets 35, and a first friction plate 34 are sequentially provided between the fixed mounting member 31 and the nut.
