A mop with a fixed mop head that pushes and pulls.

Abstract

This invention discloses a mop with a fixed mop head that is pushed and pulled. [Solution] By installing a protective frame, inner wall groove, movable column, elliptical hole, outer protrusion, elliptical cross section column, and spiral twist section, when the mop lever is manually lowered and the movable column is moved downward, the cross section I connecting column is driven and rotated, thereby joining the two sliding plates and the intermediate plastic plate through the action of the sliding plate transmission structure. After joining, the intersecting teeth of the protrusion plate and the edge teeth of the plastic plate clamp the mop head. Conversely, by holding the mop lever and protective frame and pulling them in opposite directions, the cross section I connecting column is driven and rotated in the opposite direction, thereby separating the two sliding plates from the joining position of the plastic plate through the sliding plate transmission structure, the mop head is returned to its original position, making it easy to clean, and there is no concern that repeated removal will affect its lifespan compared to conventional methods of attaching with Velcro.

Description

Technical Field

[0001] The present invention relates to the field of cleaning tool technology, and specifically to a mop that pushes and pulls a fixed mop head.

Background Art

[0002] As a common cleaning tool, a mop can not only be used to clean the floor, but also clean the wall surface, and is widely used in household cleaning. The conventional cloth strip mop has been gradually phased out with the continuous development and innovation of the tool. Currently, the most common mop is that a lever body is fitted with a plate body with a magic tape to stick the whole mop head for use.

[0003] When adopting the attachment method of magic tape bonding, it is necessary to wash the mop head after use. Therefore, it is easy to clean while always removing it. Repeated removal gradually loosens the attachment of the magic tape and affects the subsequent use effect.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In view of the problems existing in the prior art, the present invention discloses a mop that pushes and pulls a fixed mop head, and the technical solutions employed are as follows: The mop includes a mop lever, a base plate, protrusions, a mounting head, a plastic plate, mounting holes, edge teeth of the plastic plate, a sliding plate, a through groove of the sliding plate, a stabilizing plate, a stabilizing groove, an outer edge protrusion, protrusion plate teeth, a transmission structure of the sliding plate, a cross-sectional I-shaped connecting column, a through hole, an upper fixing plate, a U-shaped frame, a fixing plate 1, a fitting connecting plate, a fixing plate 2, a movable column limit disc, a protective frame, upper and lower stabilizing parts, a movable column, an elliptical hole, a cross-sectional elliptical column, and a spiral twisted part, with several protrusions distributed on the lower surface of the base plate, several hard plastic mounting heads integrally molded on the protrusions, and several plastic plates above them The mounting head is fitted and attached through a through-hole in the mounting plate, the outer diameter of the mounting head is larger than the diameter of the mounting hole, and after the mounting head is inserted into the mounting hole, the positioning hole in the plastic plate deforms to achieve a joint between the plastic plate and the mounting head, edge teeth of the plastic plate are integrally molded on the side surface of the plastic plate, the sliding plate is movable under the bottom plate, a stabilizing plate is fixed to the protrusion, a stepped stabilizing groove is made in the sliding plate, the stabilizing plate is fitted and inserted into the stepped stabilizing groove, and an outer edge protrusion is fixed to the bottom surface closer to the outside of the sliding plate, the outer edge protrusion Convex plate teeth are distributed on the inner surface of the sliding plate, and the convex plate teeth intersect with the edge teeth of the plastic plate. When the two sliding plates approach and join to the plastic plate, the convex plate teeth join with the edge teeth of the plastic plate, clamping the mop head. A transmission structure for the sliding plate is installed on the inside of the sliding plate, and the transmission structure for the sliding plate is fitted into the bottom surface of a cross-sectional I-shaped connecting column which is fitted into a through hole in the bottom plate. Two upper fixing plates are fixed to the bottom plate, the front and rear side walls of the U-shaped frame are rotatably connected to the upper fixing plates, and the left and right side walls of the U-shaped frame are rotatably connected to the protective frame.

On the other hand, the inner wall of the elliptical hole in the movable column contacts the outer wall of the elliptical prism cross-section. As the movable column continues to move downward and passes through the spiral twist section, it rotates the elliptical prism cross-section. As the elliptical prism cross-section rotates, the movable column limit disc, fixing plate 1, fitting connection plate, and fixing plate 2 below it rotate accordingly.
