Only one China utility model patent (application number: specifically disclose a kind of mop and dehydration barrel thereof 201120345105.2) in applicant's application, by the drive unit for the mophead rotation is set at mop rod, being used of special dewatering barrel in addition utilizes hand dried to taking off of up and down mobile of mop rod moment of realizing mophead in dehydration barrel.Yet in the technical scheme of above-mentioned patent, there is the phenomenon that discontinuity, interlock are unstable, easily skid in actual use in the structure that be used for to drive the rotating driving device that mophead rotates, thereby produces certain influence in the mop dewatering process.
The utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of stressed uniform and stable, and interlock better is used for the rotating driving device of mop.
The technical solution of the utility model is achieved in that a kind of rotating driving device for mop, described mop comprises mop rod and mophead, described mop rod is divided into drive rod and connecting rod, described drive rod lower end is connected with the connecting rod upper end by rotating driving device, described rotating driving device comprises screw rod, spacing button, clutch nut and clutch cover, described screw rod is positioned at drive rod, the upper end of screw rod is connected with the screw rod gland of upper end setting in the drive rod, its lower end is passed spacing button successively, clutch nut and clutch cover place connecting rod inner, threaded engagement between described screw rod and the clutch nut, described clutch cover is connected with the connecting rod upper end, the clutch nut is positioned at clutch cover, spacing button is arranged at the clutch cover upper end, in clutch cover, be provided with the glade plane space of clutch nut, it is characterized in that: on described clutch nut top, centered by clutch nut axle center, be disposed radially some projections, in described clutch cover, be provided with the unidirectional tooth with described projection corresponding matching.
Rotating driving device for mop described in the utility model, the lower surface of its described projection is curved, and the teeth groove of described unidirectional tooth partly is the arc that cooperates with the projection lower surface.
Rotating driving device for mop described in the utility model, its described some projections are evenly distributed on the same circumference centered by the axle center of clutch nut.
Rotating driving device for mop described in the utility model, its lower end at described clutch cover is provided with buffer, is fixed with spring in described screw rod gland lower end, and described spring housing is on screw rod.
Rotating driving device for mop described in the utility model, it is provided with backing pin in described screw rod lower end.
The utility model is arranged at clutch nut top with the clutch part of clutch nut and clutch cover, the mode that cooperates with unidirectional tooth in the clutch cover by clutch nut upper protruding block simultaneously, strengthened the distance of the arm of force with respect to existing structure, make stressed more stable and uniform, secondly, the form fit of projection and unidirectional tooth has strengthened both contacts area, make clutch nut and clutch cover interlock better, effectively prevented skidding.
