Description

Technical Field

[0001] The invention relates to a mop, in particular to a foldable mop head. Background Art

[0002] Mop is a tool commonly used in people's lives. Current mops can only clean the ground when mopping the floor. When mopping indoor floors, the corners adjacent to the ground are usually dirty, and current mops cannot clean the corners while mopping the floor. Therefore, most people choose to scrub with a rag by hand, which is time-consuming and laborious.

[0003] Therefore, the applicant once designed a foldable mop and submitted a patent application, specifically the invention patent application named "A foldable mop" with application number 2020215289053. It can push the mop rod back and forth to make the connecting plates on both sides fold upward, and the effect is very ideal. However, its transmission structure is relatively complicated, with many parts, and the structure needs to be further simplified. Summary of the Invention

[0004] In view of the above problems, the present invention aims to provide a foldable mop head with a simple structure, high transmission efficiency, simple operation and reliable use.

[0005] The technical solution of the present invention is a foldable mop head, comprising a base plate, a connecting cover connected to the base plate, and a padded flat mop connected to the bottom surface of the base plate, wherein folding plates connected to the padded flat mop are provided on the left and right sides of the base plate, a downwardly concave movable groove is provided in the middle of the upper surface of the connecting cover, and an inner hole is provided in the center of the movable groove, a connecting disc is provided between the connecting cover and the base plate, and a gear is fixedly connected to the central axis of the connecting disc after passing through the inner hole of the movable groove, and arc-shaped holes are provided on the left and right parts of the connecting disc with relative central symmetry, and the distance between the arc-shaped holes and the center of the connecting disc is different at different positions along the length direction of the arc-shaped holes. The folding plate is hinged with a connecting plate, and the lower surface of the inner end of the connecting plate is provided with a connecting column, the connecting column is inserted into the arc hole and the outer diameter of the connecting column is adapted to the width of the arc hole, a moving block is provided in the movable groove, and the lower surface of the moving block is provided with a tooth groove that meshes with the gear along the length direction, and the upper surface of the moving block is provided with a mop rod connecting part, and the connecting cover outside the movable groove is connected to a limit plate that limits the moving block in the movable groove; the sliding moving block drives the gear to rotate through the tooth groove, synchronously drives the connecting disc to rotate, and then pulls the connecting plate inward through the connecting column to make the folding plate fold upward.

[0006] Preferably, air-avoiding guide grooves are provided at the middle positions of the left and right sides of the connecting cover, and the connecting plate passes through the air-avoiding guide grooves and is connected to the arc-shaped hole of the connecting disc and is guided by the air-avoiding guide grooves during movement.

[0007] Preferably, a cavity for placing the gear is provided on the lower surface of the moving block, and the tooth groove is provided on one side of the cavity along the length direction.

[0008] Preferably, the limiting plate is fixed in the clamping groove of the connecting cover by means of a clamping elastic block.

[0009] Preferably, the movable groove is shaped like a waist-shaped groove.

[0010] The present invention converts the linear motion of the moving block into rotational motion through a gear rack structure, and then converts it into linear motion of the connecting plate through a special connection method between the connecting disc and the connecting column. The folding action of the folding plate is finally realized through the hinge connection between the connecting plate and the folding plate. The entire transmission structure is simple and ingenious, and is easy and safe to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 11 As shown, the present invention provides a foldable mop head, comprising a base plate 1, a connecting cover 2 connected to the base plate 1 and a padded flat mop 3 connected to the bottom surface of the base plate 1, folding plates 4 connected to the padded flat mop 3 are provided on the left and right sides of the base plate 1, a downwardly concave movable groove 5 is provided in the middle of the upper surface of the connecting cover 2, and the movable groove 5 has an inner hole in the center, a connecting disc 6 is provided between the connecting cover 2 and the base plate 1, and the central axis of the connecting disc 6 passes through the inner hole of the movable groove 5 and is fixedly connected to a gear 7, the left and right parts of the connecting disc 6 are provided with arc-shaped holes 8 that are relatively symmetrical to the center, and the distance between the arc-shaped hole 8 and the center of the connecting disc 6 is different at different positions along its length direction, and the hinge on the folding plate 4 is provided. There is a connecting plate 9, and a connecting column 10 is provided on the lower surface of the inner end of the connecting plate 9. The connecting column 10 is inserted into the arc hole 8 and the outer diameter of the connecting column 10 is adapted to the width of the arc hole 8. A moving block 11 is provided in the movable groove 5. The lower surface of the moving block 11 is provided with a tooth groove 12 that meshes with the gear 7 along the length direction, and a mop rod connecting part 13 is provided on the upper surface of the moving block 11. The connection cover 2 on the outside of the movable groove 5 is connected with a limiting plate 14 that limits the moving block 11 in the movable groove 5; the sliding moving block 11 drives the gear 7 to rotate through the tooth groove 12, and synchronously drives the connecting disc 6 to rotate, and then pulls the connecting plate 9 inward through the connecting column 10 to make the folding plate 4 fold upward.

[0025] Preferably, an air-avoiding guide groove 15 is provided in the middle of the left and right sides of the connecting cover 2, and the connecting plate 9 passes through the air-avoiding guide groove 15 and is connected to the arc-shaped hole 8 of the connecting disc 6 and is guided by the air-avoiding guide groove 15 during movement.
