Description

Locking structure of flat mop

Technical Field

The utility model relates to a flat mop especially relates to a locking structure of flat mop.

Background

The flat mop is a common floor cleaning tool, most mops are single-sided mops designed and used for common families and room floors with small areas, and the single-sided mop only has one cleaning surface for mopping the floor, so that the cleaning surface needs to be cleaned for many times in the mopping process. The double-sided flat mop has two cleaning surfaces, so that the cleaning efficiency can be improved, however, when the double-sided flat mop is used for dewatering operation, one hand is needed to hold the mop rod for positioning, the other hand is used to hold the water squeezing mechanism, the relative squeezing motion between the water squeezing mechanism and the flat mop is realized by pushing and pulling the water squeezing mechanism with one hand, the operation is very laborious, and the operability is not strong.

In order to solve the above problems, some have invented a flat mop cleaning tool without folding and vertically drying the flat mop head, for example, a structure disclosed in the chinese utility model patent No. CN201720655739.5 (publication No. CN207755232U) and the chinese invention patent application No. CN2018104132736.2 (publication No. CN108158523A) discloses a flat mop cleaning tool, and during drying, the flat mop head needs to be rotated to a state where the length direction thereof is the same as the axial direction of the mop rod, and is kept in the state by a locking structure.

The locking structure that aforementioned patent discloses is similar, and locking structure is including locating the bolt in getting rid of the dry district and locating the lockhole in the joint, and overhead the opening of dull and stereotyped mop has the passageway that runs through the downside of dull and stereotyped mop head, and under the state that its length direction of dull and stereotyped mop head is the same with the axis direction of mop pole and inserts in getting rid of the dry district, the bolt passes direct or indirect insertion lockhole behind the passageway. Or, the locking structure is including locating the bolt in getting rid of the dry district and locating in the dull and stereotyped mop head and can follow the lock frame that its length direction slided, the downside of dull and stereotyped mop head is equipped with and supplies bolt male passageway, be equipped with limit structure between lock frame and mop pole or the joint, the trend that the lock frame kept moving towards the downside direction of dull and stereotyped mop head is held by the second spring top, the lock frame shifts up, limit structure is spacing together with mop pole or joint with the lock frame, the lock frame moves down, limit structure relieves the spacing between lock frame and mop pole or the joint under dull and stereotyped mop head rotates to its length direction and the same with the axis direction of mop pole and inserts the state in getting rid of the dry district, the bolt inserts the passageway and then triggers the lock frame to shift up.

No matter what kind of locking structure, it all needs set up the bolt that is used for triggering the locking in the district that spin-dries, and the structure is more complicated moreover, and in addition, the mop is at unused state, and locking structure can not realize the locking, and dull and stereotyped mop head can only rotate to the state of mopping (that is the cleaning surface of dull and stereotyped mop head is shelved subaerial) and deposit, and it is big to place the space, and easily ponding between the cleaning surface of dull and stereotyped mop head and ground.
