Abstract

A quickly assembled and disassembled nut comprises a socket component allowing plugging of a bolt, wherein one or more threaded pushing blocks in connection and disconnection match with the bolt are arranged on the socket component slidably and radially, a lock sleeve capable of driving and performing lock controlling on slide of the threaded pushing blocks is in sleeved connection with the socket component slidably and radially, and an elastic part driving the lock sleeve to reset abuts between the lock sleeve and the socket component. Locking blocks and unlocking blocks are arranged between the lock sleeve and the threaded pushing blocks, the locking blocks are used for driving the threaded pushing blocks to reset radially and inwards when the lock sleeve slides forwards to perform locking, and the unlocking blocks are used for driving the threaded pushing blocks to perform radial outward movement when the lock sleeve slides backwards to perform unlocking. Forward sliding locking and backward sliding unlocking of the lock sleeve drive the threaded pushing blocks to be in disconnection and connection match with the bolt, and rapid plugging of the bolt is achieved without multi-turn screwing in or out. When screwed tightly, the quickly assembled and disassembled nut can be universally matched with universal bolts like other nuts and matched with toilet closets different in wall thicknesses at the positions of installation holes to fix the toilet closets on the installation holes firmly. The quickly assembled and disassembled nut is simple in structure, convenient to assemble and disassemble and reliable in assembly and disassembly function.
