Positioning structure for server, rack and computing device

A rack comprising:

• a rack body;
• and
• a positioning structure configured for positioning a server on the rack body, the positioning structure comprising:
• a chassis defining a cavity configured for accommodating the server and a first opening configured for the server moving into or out of the cavity in a first direction;
• a door rotatably connected to the chassis and configured for opening or covering the first opening;
• a locking piece movably connected to the door, the locking piece comprising a first bevel;
• a first elastic piece connected to the locking piece and the door;
• and
• a handle movably connected to the door, the handle comprising a handle main body, the handle main body comprising a second bevel contacting the first bevel in parallel,
• wherein when the door covers the first opening, the first elastic piece moves the locking piece into a slot of the chassis to position the door, when the door covers the first opening and the handle main body moves away from the chassis in the first direction, the second bevel moves the locking piece by pushing the first bevel in a second direction perpendicular to the first direction, and the locking piece moves out of the slot so that the door can be opened.

A computing device comprising:

• a plurality of servers;
• and
• a rack comprising:
• a rack body;
• and
• a plurality of positioning structures configured for positioning the plurality of servers on the rack body, each of the plurality of positioning structures comprising:
• a chassis defining a cavity configured for accommodating each of the plurality of servers and a first opening configured for each of the plurality of servers moving into or out of the cavity in a first direction;
• a door rotatably connected to the chassis and configured for opening or covering the first opening;
• a locking piece movably connected to the door, the locking piece comprising a first bevel;
• a first elastic piece connected to the locking piece and the door;
• and
• a handle movably connected to the door, the handle comprising a handle main body, the handle main body comprising a second bevel contacting the first bevel in parallel,
• wherein when the door covers the first opening, the first elastic piece moves the locking piece into a slot of the chassis to position the door, when the door covers the first opening and the handle main body moves away from the chassis in the first direction, the second bevel moves the locking piece by pushing the first bevel in a second direction perpendicular to the first direction, and the locking piece moves out of the slot so that the door can be opened.
