Structure of wringable mop

Abstract

A wringable mop includes a transmission unit mounted with a driven cap at the bottom side of an actuating sleeve that is rotatable and axially movable relative to the handle unit, a cleaning body connected between the handle unit and the driven cap, and a positioning unit controlling rotation and axial movement of the actuating sleeve relative to the handle unit. When the positioning unit controls one-way rotation of the actuating sleeve relative to the handle unit, the handle unit and the actuating sleeve are rotated relative to each other to cause rotation of the driven cap relative to the handle unit, and therefore the cleaning body is twisted.

1 . A wringable mop, comprising:
 a cleaning body, said cleaning body having two opposite ends   a handle unit, said handle unit having a first end, a handle at said first end, a second end opposing said first end and affixed to one end of said cleaning body;   an actuating sleeve sleeved onto said handle unit and rotatable and axially movable relative to said handle unit;   a driven cap connected between one end of said actuating sleeve and the other end of said cleaning body and rotatable and axially movable relative to said handle unit;   a transmission unit mounted between one end of said actuating sleeve and said driven cap and rotatable and axially movable by said actuating sleeve relative to said handle unit;   a positioning unit mounted on said actuating sleeve and adapted for controlling rotation and axial movement of said actuating sleeve relative to said handle unit;   an operating member sleeved onto said actuating sleeve and movable axially to cause rotation of said actuating sleeve; and   a telescopic sleeve sleeved onto the second end of said handle unit and received in said driven cap and inserted into said cleaning body in such a manner that said telescopic sleeve and said handle unit and said actuating sleeve are separately movable relative to one another, said telescopic sleeve being comprised of a plurality of tubular elements that slide one inside another;   wherein when said positioning unit controls said actuating sleeve for rotation in one direction relative to said handle unit, rotating said handle unit relative to said actuating sleeve causes rotation of said transmission unit relative to said handle unit in twisting said cleaning body.   
   
   
       2 . The wringable mop as claimed in  claim 1 , wherein said actuating sleeve comprises a plurality of outer spiral threads; said operating member comprises a plurality of inner spiral threads meshed with the outer spiral threads of said actuating sleeve in such a manner that moving said operating member axially causes rotation of said actuating sleeve. 
   
   
       3 . The wringable mop as claimed in  claim 1 , wherein said transmission unit comprises a set of gears mounted on said driven cap and meshed between said handle unit and said actuating sleeve. 
   
   
       4 . The wringable mop as claimed in  claim 1 , wherein said driven cap comprises a transversely extending top wall, a plurality of upright axles disposed at said transversely extending top wall, and a threaded top neck extending around said transversely extending top wall; said actuating sleeve comprises a bottom gear house, an internal gear fixedly mounted inside said bottom gear house, and an internally threaded locating ring capped on said gear house and threaded onto said threaded top neck of said driven cap; said transmission unit comprises a plurality of planet gears respectively mounted on said upright axles of said driven cap and meshed between said handle unit and said internal gear. 
   
   
       5 . The wringable mop as claimed in  claim 1 , wherein said handle unit comprises:
 a handle, said handle having a grip at a top end thereof;   a toothed bar, said toothed bar comprising a plurality of longitudinal teeth arranged around the periphery thereof; and   an adapter coupling said toothed bar to said handle, said adapter comprising a coupling tube comprising a tubular body sleeved onto a top end of said toothed bar, a plurality of linear teeth longitudinally arranged around the periphery of said tubular body and sloping in one direction, a threaded head, a neck connected between said tubular body and said threaded head, a pinhole transversely cut through the neck of said adapter, a plurality of clamping strips axially extending from said threaded head, an coupling space defined within said clamping strips and adapted for receiving a bottom end of said handle, a collar threaded onto said threaded head of said coupling tube to radially inwardly compress said clamping strips against the periphery of the bottom end of said handle and to secure said coupling tube to said handle, and a lock pin inserted through said pinhole of said coupling tube and the top end of said toothed bar to lock said coupling tube to said toothed bar.   
   
   
       6 . The wringable mop as claimed in  claim 5 , wherein said toothed bar is inserted through said transmission unit to have the longitudinal teeth thereof in mesh with said planet gears of said transmission unit such that rotating said handle causes said toothed bar to rotate said transmission unit and said driven cap. 
   
   
       7 . The wringable mop as claimed in  claim 5 , wherein said positioning unit is mounted in a top end hole of said actuating sleeve, comprising a plurality of C-shaped retaining rings and respectively clamped on said coupling tube of said adapter and an annular stop member sleeved onto said coupling tube of said adaptor and adapted to limit rotation of said adapter in one direction, said annular stop member comprising an engagement portion for engaging the linear teeth of said coupling tube; when moving said actuating sleeve and said transmission unit and said driven cap axially relative to said handle unit to let said annular stop member enter into said actuating tube and go through said C-shaped retaining rings and said annular stop member, said actuating sleeve is rotatable relative to said handle unit in one direction and prohibited from rotation relative to said handle unit in the reversed direction, and at the same time said C-shaped retaining rings are clamped on the neck of said coupling tube to keep said annular stop member in said actuating sleeve. 
   
   
       8 . The wringable mop as claimed in  claim 1 , wherein said cleaning body comprises a plurality of soft strands of water-absorbing fabric, and a resilient wire member axially embedded in each said soft strand of water-absorbing fabric. 
   
   
       9 . The wringable mop as claimed in  claim 1 , wherein said telescopic sleeve is mounted in said cleaning body between said handle unit and said driven cap and axially movable relative to said handle unit and said actuating sleeve and said driven cap. 
   
   
       10 . The wringable mop as claimed in  claim 1 , wherein said driven cap comprises an inside annular retaining portion stopped against a rim at a top side of said telescopic sleeve such that said telescopic sleeve is received together inside said driven cap when lifting said handle unit relative to said driven cap and said actuating sleeve. 
   
   
       11 . The wringable mop as claimed in  claim 5 , wherein said coupling tube of said adapter further comprises a top extension tube axially upwardly extending from said threaded head and inserted into the bottom end of said handle. 
   
   
       12 . The wringable mop as claimed in  claim 5 , wherein said coupling tube of said adapter further comprises two beveled guide edges respectively extending around the periphery of top and bottom ends of said tubular body.
