Locking device, and chassis with the locking device

A locking device for installing a second component into a first component, the locking device comprising:

• a blocking element configured to be installed on the first component;
• a fixing element configured to be installed on the second component;
• an operating element movably arranged on the fixing element, and defining a chute;
• and
• a locking component, wherein
• the chute comprises a third groove section, the locking component comprises:
• a connection element movably connected within the chute;
• a locking element rotationally arranged at the fixing element;
• and
• a link module which comprises:
• a first link member rotatably connected to the locking element and the connection element;
• a second link member rotatably connected to the fixing element and the connection element;
• and
• a holding member connected to the fixing element and the second link member to generate elastic torque on the second link member and achieve stable positioning of the connection element in the third groove section;
• and
• the operating element is subjected to force to move the connection element within the chute, and to rotate the first and second link member of the link module and drive the locking element to lock or detach from the blocking element.

A chassis comprising:

• a casing;
• a memory module;
• and
• a locking device, wherein:
• the locking device comprises:
• a blocking element configured to be installed on the first component;
• a fixing element configured to be installed on the second component;
• an operating element movably arranged on the fixing element, and defining a chute;
• and
• a locking component comprising:
• a connection element movably connected within the chute;
• a locking element rotationally arranged at the fixing element;
• and
• a link module, comprising at least two connected connecting link members, one end of the link module is rotationally connected to the fixing element, while another end is rotationally connected to the locking element, and a portion between the two ends of the link module is rotationally connected to the connection element;
• the operating element is subjected to force to move the connection element within the chute, and to rotate the link member of the link module and drive the locking element to lock or detach from the blocking element;
• the fixing element is arranged on the memory module, the blocking element is arranged on the casing, and the memory module is detachably installed in the casing through the locking device.
