Abstract

The invention discloses an ultra-speed centrifugal machine, and particularly relates to the technical field of centrifugal machines, the ultra-speed centrifugal machine comprises a rotor device, and a central cavity is formed in the top of the rotor device; a centrifugal cylinder; an extension structure at the bottom of the sealing cover can be inserted into the central cavity; the locking unit comprises a locking block; the driving unit comprises a center pressing rod, the center pressing rod penetrates through the through hole of the sealing cover and is pressed downwards into the locking unit to push the locking block to move transversely, and then the extending structure at the bottom of the sealing cover is locked through the locking block; according to the rapid locking mechanism based on the axial driving-radial expansion principle, after the sealing cover is placed in place, the center pressing rod is vertically pressed downwards, the locking block can be synchronously driven to expand in the radial direction through the upper conical surface and the lower conical surface of the center pressing rod, and clamping of a sealing cover insertion pipe is instantly completed; the tedious thread alignment and multi-circle screwing process is completely eliminated, and the risk of part damage caused by thread dislocation is fundamentally eradicated.
