The invention discloses a turnover mechanism, a
server case and a
server, and relates to the technical field of servers, the turnover mechanism comprises a support, a tray and a deviation rectifying
assembly, the tray is hinged to the support, the tray can rotate around the support in the first direction, and the deviation rectifying
assembly is configured to drive the tray to move in the second direction perpendicular to the first direction; the
server is provided with a box body and a turnover mechanism, nodes of the server can be arranged on the box body and a tray of the turnover structure of the server in a layered mode, when the server nodes arranged on the box body are maintained, the server nodes of the box body can be maintained only by turning over the tray of the turnover mechanism, and the deviation rectifying
assembly can rectify deviation of the server nodes of the box body in the turnover process of the tray. According to the technical scheme, the tray is rectified, so that the tray is always overturned within the range of not touching other devices in the case body, the technical problem that the tray is easy to touch other devices in the case in the overturning process can be effectively solved, and the technical effect of facilitating maintenance of server nodes is achieved.
