Description

Device for wringing mop

Technical Field

The invention relates to a device for wringing a mop.

Background

While mops used to scrub the floor require cleaning in water and wringing out, the earliest forms of wringing out with the hands not only contact dirty water but are also laborious and difficult for smaller people to handle and wring out. To solve this problem, various devices have been proposed for wringing out mops, mainly in two forms, one with squeezing of the jaws and the other with centrifugal throwing. Although the two devices can dewater the mop to a certain degree, the former type has uneven extrusion force, some parts cannot be extruded or the extrusion force is insufficient, so that more water is reserved, and the latter type of mop needs to be specially made, so that the common bundled mop cannot be applied. And the mop wringing device is characterized in that an inner sleeve is arranged on the handle of the mop, a yarn rope is fixed between the inner sleeve and the outer sleeve to be used as a mop cloth strip, and water in the yarn rope is squeezed out when the inner sleeve is rotated in the opposite direction. However, the mop wringing device of this structure also has a problem that special mop strips are required, and the mop cannot be bound with old mop strips by waste utilization as in the conventional mop.

Detailed Description

As shown in fig. 1, 2, 3 and 4, there is a barrel 1, one side of the barrel is attached with a compartment 5, the compartment is separated from the barrel by a barrel wall, and a vertical plate 8 as a shaft seat is arranged in the compartment for installing an operation part of the screwing device. The barrel is provided with a tightening mechanism at the upper part and the lower part, the upper tightening mechanism is a clamp 3, and the lower tightening mechanism is a claw 17.

The pivot of the pincer-shaped object is fixed on the inner wall of the barrel through shaft seats at two ends, the pivot is vertical to the bottom of the barrel, the jaw of the pincer-shaped object is opened and closed transversely, and the handle of the pincer-shaped object penetrates through the barrel wall and enters the compartment. The hooping adjusting wheel 4 is arranged in the bulkhead through a camshaft 7 by taking the outer wall of the bulkhead and a vertical plate as a shaft seat, and the hooping adjusting wheel is arranged between the two forceps handles, namely the hooping adjusting wheel is a cam taking the forceps handles as a driven part. The contour of the tightening adjusting wheel is S-shaped with central symmetry, so that every time the tightening adjusting wheel rotates 90 degrees, the contour of the tightening adjusting wheel forms a large transverse width and a small transverse width which take the pivot as a midpoint, and a reset spring which enables the pliers to tend to open is arranged on the pliers handle. A cam-like cam wheel 18 is mounted on the camshaft and a fixed mounting angle is provided between the cam wheel and the pinch adjusting wheel. An arc-shaped moving cam 6 taking a curve wheel as a driven part is arranged, and the moving cam and the curve wheel are matched to form a cam mechanism. The initial section of the inner side surface of the moving cam is provided with a radius which falls suddenly, the section after falling suddenly is an arc section, and the cliff wall surface formed by falling suddenly on the moving cam and the convex part on the curve wheel form a poking point. The arc section and the arc part on the curve wheel form a sliding section. The contour of the curve wheel is provided with a section of plane, and the two ends of the plane are matched with the arc section on the moving cam in a small clearance manner to form translational matching. The central angle between the connecting line of the plane central point and the cam shaft and the connecting line of the toggle point and the cam shaft is 90 degrees.

The claw-shaped object is a group of elastic pieces with one end fixed on the rotating disc and pointing to the opening of the barrel, the claw-shaped object is in an open initial state, a tightening rope 12 is wound outside the claw-shaped object elastic pieces, one end of the tightening rope is fixed on the wall of the barrel, and the other end of the tightening rope is fixed on a rotating disc 13. When the rotating disc rotates, one end fixed on the rotating disc pulls the tightening rope to rotate, but the other end is fixed on the barrel wall, so that a ring surrounded by the tightening rope is smaller and smaller, and the elastic sheet is folded to play a role of hooping the lower part of the mop cloth strip during rotation. The turntable is mounted on the base of the barrel via a vertical shaft 16, and a coaxial gear 15 is also provided beneath the turntable. The teeth of the coaxial gears are positioned on the end face of the gear cylinder, a first transmission gear 14 is meshed with the coaxial gears, and a transmission shaft 11 for mounting the first transmission gear penetrates through the barrel wall and is mounted on the vertical plate and the outer wall of the compartment. A second transmission gear 19 is arranged on the part of the transmission shaft on the compartment, an arc-shaped driving rack 10 is meshed with the second driving gear by teeth in an inner arc, and the driving rack is arranged between the vertical plate and the outer wall of the compartment by a short shaft at the center of the arc.

Inside the compartment, a pedal 61 is mounted between the vertical plate and the outer wall of the compartment via a hinge 9, forming a swinging lever hinged to the tub. The arc-shaped moving cam is fixedly connected with the pedal through the connecting arm, and the arc-shaped circle center of the moving cam is arranged on the hinged shaft. The installation relation among the pedal, the moving cam, the curve wheel and the tightening adjusting wheel is that when the pedal is stepped downwards from the upper end, the tightening adjusting wheel can rotate 90 degrees at the beginning of stepping, namely the tightening adjusting wheel changes from the minimum to the maximum from the transverse width, so that the pincerlike object is inwards closed to tighten the mop, and then the pincerlike object is not subjected to the driving force of closing any more when staying at the angle. A shifting pin 101 is arranged on the side surface of the driving rack, a long groove 62 is arranged on the pedal and matched with the shifting pin, and a long groove shifting pin mechanism formed by the long groove and the shifting pin enables the driving rack to swing along a central shaft when the pedal is stepped downwards, so that the second transmission gear is driven to rotate. The installation relation of the pedal, the driving rack, the transmission gear and the turntable is that when the pedal is stepped downwards, the rotation direction of the turntable is the direction indicated by one end of the tightening rope fixed on the turntable, so that when the pedal is stepped, the turntable is rotated to tighten the tightening rope. The pedal is connected with the compartment through a return spring, so that the initial position of the pedal is at the highest position, and the lower part of the compartment front wall 51 is an arc wall which takes a pedal hinge shaft as the center and has a radius smaller than the length of the pedal.

When the mop is in use, the vertical cloth strip of the mop [2] is put downwards from the upper opening of the bucket, the pedal is stepped down, the clamp-shaped object firstly hoops the position where the mop handle is bundled with the cloth strip, and then the lower part of the cloth strip is tightened while the jaw-shaped object rotates, so that water in the cloth strip is squeezed out and wrung out.
