Description

Linkage unlocking device for mop cleaning barrel

Technical Field

The invention relates to the technical field of daily necessities, in particular to a linkage unlocking device for a mop cleaning barrel.

Background

The mop is a long-handle cleaning tool for scrubbing the ground, also called a mop rag, and also widely called a long-handle cleaning tool, the mop is derived from the rag, the most traditional mop is formed by bundling a bundle of cloth strips at one end of a long wood rod, the mop is simple and cheap, and the working head is changed into the bundle of cloth strips from a rag block, so that the mop has strong dirt-removing capability. After long-term use, new problems come, the mop head, which is a working part of the mop, needs to be continuously cleaned, and the damage of the cleaning of the mop head to the hands of an operator is increased, so that the problem to be solved is solved. Along with the continuous growth of scientific trees, materials used by the mop head are gradually extensive, non-woven fabrics, superfine fibers and the like are developed from early cotton cloth strips, even a piece of collodion (collodion mop) is directly used, and the collodion mop is more suitable for clearing accumulated water on the ground such as a kitchen, a toilet and the like due to the strong hydroscopicity of the collodion and the matching of a convenient water squeezing device. The crank mop moves the head ribs on the mop rod, the crank component is additionally arranged on the traditional straight rod, so that the mop head can freely rotate on the ground, labor is saved, the problem that the straight rod mop is stood down to be labored and garbage scraps are pushed away to be stored under the mop head is solved, and meanwhile, the crank can provide power for the high-speed rotation and thorough cleaning of the mop.

So far, the functions of the mop are continuously expanded, and the auxiliary tools are diversified, which presents a situation of hundreds of flowers. The existing improvement is mainly carried out on a mop head and a mop rod, or a special barrel is provided to be matched with the mop head to realize the function of automatic spin-drying or wringing. At present, most mops are cleaned without matched mop barrels, and only the mops are cleaned in a common water container, so that when the mops are mopped and cleaned, water in the container is more and more dirty, floating objects such as hair and debris exist, the mops are difficult to clean again, the mops can be kept clean only by frequently changing water, water resources can be seriously wasted, and waste is caused.

As shown in fig. 4b, the water outlet 22 is completely closed, and at this time, since the upper end surface of the third guiding column 267 is lower than the lower end surface of the second locking module 70b, the slider 72 in the second locking module 70b moves to the left under the action of the third compression spring 74, so that the stopper 723 of the second locking module 70b blocks the third guiding column 267, thereby restricting the upward movement of the flapper 26, and the flapper 26 maintains the closed state of the water outlet 22 under the elastic force of the fourth compression spring 265.

In the state of fig. 4b, the wringing plate 30 continues to move downwards, the first guide column 28 abuts against the wedge-shaped surface of the second groove 722 of the first locking module 70a, and with the continued downward movement of the wringing plate 30, the slider 72 of the first locking module 70a moves leftwards and compresses the third compression spring 74 until, in the state shown in fig. 4c, the first locking module 70a is unlocked, and the wringing plate 30 and the baffle 26 can move independently, and during the period of time, the wringing plate 30 pushes the baffle 26 to move downwards for a short stroke until the first locking module 70a is unlocked, and the length of the stroke is equal to the height of the first locking module 70 a.

The wringing plate 30 continues to move downwards according to the state shown in fig. 4c, and when the wringing plate reaches the state shown in fig. 4d, the fourth guide column 37 abuts against the wedge-shaped surface of the second locking module 70b, and pushes the second locking module 70b to unlock along with the continuous downward movement of the wringing plate 30.

When the wringing plate 30 moves to the position shown in fig. 4e, the second locking module 70b is unlocked, and the baffle 26 moves upward under the elastic force of the fourth compression spring 265, so that the water outlet 22 is opened.

When the wringing plate 30 moves upwards, the locking state of the first locking module 70a and the second locking module 70b is not changed, and the water outlet 22 is always kept in the open state, as shown in fig. 4 f. When the wringer plate 30 is about to move to the top position, it becomes the state shown in fig. 4a, i.e., the first locking module 70a is locked.

After the structure is arranged, the unlocking and the locking are mechanical structures, the use is very reliable, the linkage process is very smooth, and the actual operation of a user is only as follows: the water squeezing plate 30 is pressed downwards by the mop, and the water squeezing plate 30 can automatically realize the actions of closing the water outlet 22, maintaining the closed state of the water outlet 22 and opening the water outlet 22; after the user unlocks the wringing plate 30, the wringing plate 30 automatically moves up and resets.
