Rotary mop

Abstract

A rotary mop is provided in which an inner rod body is arranged to be coaxial with an outer rod body. The outer rod body is attached with a transmission stem which is provided with a ratchet block. A drive block inserted with the transmission stem is to engage with the ratchet block. A sleeve is assembled in the inner rod body and helical grooves are provided on the peripheral wall of the sleeve for engaging with guiding posts provided on the drive block. A mop section is mounted on the bottom of the sleeve. In this manner, the transmission stem can move the drive block to rotate the sleeve when the outer rod body is repeatedly pushed and pulled, and the mop section mounted on the bottom of the sleeve can be stably rotated to drain out the water contained in mop strings.

1 . A rotary mop, wherein an inner rod body is arranged to be coaxial with an outer rod body, a transmission stem fixed with a ratchet block thereon being internally assembled in said outer rod body, a drive block being further inserted to said transmission stern for engaging with said ratchet block, a baffle piece being disposed on the bottom end of said transmission stem for limiting said drive block, a sleeve which is assembled within said inner rod body having helical grooves provided on the peripheral wall thereof for engagement with guiding posts provided on said drive block, and a mop section being mounted on the bottom end of said sleeve. 
     
     
         2 . The rotary mop as claimed in  claim 1 , wherein one-way ratchet teeth are formed respectively on said ratchet block and said drive block for mutual engagement. 
     
     
         3 . The rotary mop as claimed in  claim 2 , wherein said sleeve is formed with at least two helical grooves opposite to each other. 
     
     
         4 . The rotary mop as claimed in  claim 3 , wherein said helical grooves of said sleeve are formed on the inner peripheral wall surface of said sleeve. 
     
     
         5 . The rotary mop as claimed in  claim 3 , wherein said helical grooves of said sleeve are formed to be projected from the inner peripheral wall surface to the outer peripheral wall surface. 
     
     
         6 . The rotary mop as claimed in  claim 1 , wherein said mop section further comprises a coupling rod mounted on the bottom end of said sleeve, a disk body pivotally connected to the bottom side of the coupling rod, and a mop strings mounted on the bottom of said disk body. 
     
     
         7 . The rotary mop as claimed in  claim 1 , wherein said rotary mop further has a lock member which includes a retaining bush inserted in the bottom edge of the outer rod body, a groove provided on the side of the retaining bush being in coincidence with a groove provided on the side of the outer rod body, a press lever being pivotally coupled in the groove of the retaining bush, and an abutment portion being formed on the end portion within the groove for abutting firmly on the wall surface of said inner rod body. 
     
     
         8 . The rotary mop as claimed in  claim 1 , wherein said helical grooves of said sleeve are formed on the inner peripheral wall surface of said sleeve. 
     
     
         9 . The rotary mop as claimed in  claim 1 , wherein said helical grooves of said sleeve are formed to be projected from the inner peripheral wall surface to the outer peripheral wall surface of said sleeve. 
     
     
         10 . The rotary mop as claimed in  claim 1 , wherein a plug block is assembled in the hollow portion of said inner rod body and a through bore is provided at the center of said plug block for traversing of the transmission stem, said drive block and said ratchet block of said transmission stem being located beneath said plug block. 
     
     
         11 . The rotary mop as claimed in  claim 1 , wherein said sleeve is formed with at least two helical grooves opposite to each other. 
     
     
         12 . The rotary mop as claimed in  claim 11 , wherein said helical grooves of said sleeve are formed on the inner peripheral wall surface thereof. 
     
     
         13 . The rotary mop as claimed in  claim 11 , wherein said helical grooves of said sleeve are formed to be projected from the inner peripheral wall surface to the outer peripheral wall surface of said sleeve.
