Labor-saving spiral mop

The invention relates to a mop rod, which refers to a labor-saving spiral mop rod which is compressed and generates rotation.

The mop is a common cleaning tool in daily life. The mop is composed of a rod body, a mop head and a cotton rope. The mop head is placed at one end of the rod body, and the absorbent cotton rope is arranged at the mop head. Immerse in the bucket and absorb the water. The dissolving characteristics of the water through the cotton rope can be used to remove the dirt on the floor. After the cotton rope of the mop absorbs the water, it needs to be dehydrated to filter out the excess water. The traditional mop is Using manual writting, this method is more laborious and causes dirt on the hands.

To this end, a rotary mop is developed to pivot the mop head to the rod body, so that the mop head and the cotton cord can be freely rotated relative to the rod body, and then combined with a specific dewatering bucket, the dewatering bucket is provided with a dewatering frame and a driving device. The dewatering frame is pivoted in the dewatering bucket, and the driving device is connected to the dewatering frame. When in use, the mop head and the cotton rope are placed in the dewatering frame, and the driving device is stepped on to drive the dewatering frame and the deheading head to rotate, by rotating The centrifugal effect produced achieves the purpose of dehydration.

The existing rotary mop is used together with the dewatering bucket with the driving device. The structure of the dewatering bucket is complicated and high in cost, and the driving device is provided in the dewatering bucket, so that there are many dead corners in the bucket which are not cleaned well, and the dewatering is performed. The barrel has the disadvantages of heavy weight and low water loading. In addition, it is necessary to hold the handle and the pedaling device at the same time during the dehydration process.

In view of the above-mentioned shortcomings of the prior art, the present invention improves the existing rotary mop, so that the present invention has the function of compression and rotation, which has the advantages of simple operation and cost saving.

In order to achieve the above object, the technical means adopted by the present invention is to provide a labor-saving spiral mop rod, which comprises: a grip rod, which is a hollow rod body; an outer rod, which is disposed at the grip rod, and the outer rod is set The utility model has an accommodating space and a concave threaded portion. The accommodating space is formed on the outer rod and penetrates the two ends of the outer rod, and the concave threaded portion is formed around the inner side wall surface of the outer rod; and an inner rod is disposed on the outer rod The mounting space is provided with a mounting hole formed at one end of the inner rod; a rotating component connected to the inner rod, the rotating assembly has a pushing block and a spiral block, and the pushing block is disposed in the mounting hole and is provided There is a protruding and forming guide rod, the spiral block is penetrated by the guiding rod and is snapped against the block, the spiral block is located in the outer rod, and the outer wall surface of the spiral block is provided with a plurality of spiral lugs, and the spiral lug is engaged a female threaded portion of the outer rod; a fixing device disposed on the outer wall surface of one end of the outer rod and away from the grip rod, and selectively abutting against the inner rod to prevent the inner rod from rotating relative to the outer rod.

Through the engagement of the concave threaded portion of the rod and the spiral projection of the spiral block of the present invention, when the external rod is pressed by an external force, the spiral block can be rotated in the outer rod, and then the block is pushed by the spiral block to push the block. The inner rod is caused to rotate. In practical applications, the mop head and the cotton rope are loaded on the other end of the inner rod, and have a dehydrating function by the rotation characteristic caused by the hand pressing. When the dehydration is completed, the fixing device is pulled to make the inner rod The present invention has a simple use and is not required to be stepped on by a rotary dewatering bucket and legs.
