Claim 0:
1. A compressor rotor, comprising:
a motor rotor comprising a plurality of rotor sections fixedly connected in an axial direction, wherein the plurality of rotor sections are provided with an axial through hole;
a locking rod penetrating through the axial through hole;
a compression unit rotating part located on an end of the motor rotor and connected to the locking rod; and
a locking member configured to lock the compression unit rotating part on the locking rod, wherein the locking rod, the compression unit rotating part, and the locking member form a pressing structure which applies a pressure toward an axial inner side to the motor rotor;
wherein the axial through hole comprises a small-diameter section and two large-diameter sections which have a larger diameter than the small-diameter section;
the locking rod comprises a rod body in clearance fit with the small-diameter section and two protrusion parts arranged on the rod body and radially protruding outwards from the rod body, wherein the protrusion parts are fit with the large-diameter section;
an axial middle part of the motor rotor comprises a permanent magnet, the small-diameter section is located at an axial middle part of the axial through hole;
the two large-diameter sections are respectively located at a first end and a second end of the axial through hole;
at least one of the two protrusion parts is a movable protrusion part movable relative to the rod body;
the rod body is provided with a shaft shoulder, and the movable protrusion part is arranged between a surface of one end of the motor rotor and the shaft shoulder;
the compression unit rotating part at one end of the motor rotor where the movable protrusion part is arranged comprises an axial lug boss;
the axial lug boss extends into the axial through hole; and
the movable protrusion part is axially arranged between the shaft shoulder and an end face of the axial lug boss.
