[0002] A Chinese utility model patent with the publication number CN217547970U discloses a mop bottom plate for easily fixing a mop cloth. The mop bottom plate includes a bottom plate body provided with an iron block and a pair of mounting blocks provided with magnets. Then, the mop cloth is fixed to the mop main body by the mutual attraction between the bottom plate main body and the pair of mounting blocks.

[0003] However, the above-mentioned mop bottom plate has the technical problem that it cannot switch the inner and outer surfaces of the mop cloth. That is, when the outer surface (the side surface exposed to the outside) of the mop cloth is soiled, the relatively clean inner surface (the side surface not exposed to the outside) cannot be switched to the outside. This makes it necessary for the user to frequently replace the mop cloth during the cleaning operation, which reduces the cleaning efficiency to a certain extent. In addition, the frequent cloth replacement operation also causes the user's hands to be repeatedly contaminated by the soiled mop cloth, which is not conducive to the health of the user. When cleaning large-scale places such as hotels and supermarkets, the inconveniences caused by the above technical problems are particularly prominent. Summary of the Invention

[0019] In the present application, the observation perspective when the user pushes forward the mop clamping tool supported on the horizontal plane is used as the reference for the directions of "up", "down", "left", "right", "front" and "back".

[0020] Figure 1-2The mopping cloth clamping tool 100 provided by the present invention is shown. A user can attach it to the end of a handle-shaped object to perform cleaning operations on various types of surfaces to be cleaned, such as the ground, windows, walls, etc. Specifically, the mopping cloth clamping tool 100 includes a mopping cloth clamping plate 1 that can clamp the mopping cloth 10, a mopping cloth pressing plate 2 that is liftably connected to the mopping cloth clamping plate 1, and a lifting mechanism that enables the liftable connection between the mopping cloth pressing plate 2 and the mopping cloth clamping plate 1.

[0021] Combined with Figure 7 , the mopping cloth clamping plate 1 is in the shape of a cuboid and includes a frame 1 and a pair of mopping cloth pressing strips 12 rotatably connected to the frame 11. The frame 1 is enclosed by a pair of front and rear opposite transverse plates 111 and a pair of left and right opposite longitudinal plates 112. The frame 1 defines a cloth pressing space 113 located in the middle and penetrating the mopping cloth clamping plate 1 in the up and down directions.

[0022] A pair of mopping cloth pressing strips 12 are relatively arranged on the front and rear sides of the cloth pressing space 113 and can respectively press one end of the mopping cloth against the frame 11 to fix the mopping cloth on the mopping cloth clamping plate 1 and make at least part of the mopping cloth located in the cloth pressing space 113. Specifically, connection ends 114 and limit bosses 115 that are far away from each other in the left and right directions are provided on each transverse plate 111, and both the connection ends 114 and the limit bosses 115 protrude upward. The mopping cloth pressing strip 12 is rotatably connected to the corresponding side transverse plate 111 around a first axis Y1 extending in the front and rear directions. Each mopping cloth pressing strip 12 includes a connection portion 121 close to the first axis Y1, a locking portion 123 far away from the first axis Y1, and a main body portion 122 extending from the connection portion 121 to the locking portion 123. Among them, the connection portion 121 of the mopping cloth pressing strip 12 is rotatably connected to the connection end 114 of the corresponding side transverse plate 111.

[0023] Combined with Figure 8 , the locking portion 123 of each mopping cloth pressing strip 12 includes a deformable U-shaped plate 124, a limit rib 125 fixedly arranged on the U-shaped plate 124, and an unlocking rib 126 fixedly arranged on the upper side of the limit rib 125. A step structure (not shown in the figure) adapted to the limit rib 125 is provided on the limit boss 115 of the transverse plate 111. When the mopping cloth pressing strip 12 is pressed against the corresponding transverse plate 111, the U-shaped plate 124 is biased on the limit boss 115 and deforms to keep the mopping cloth pressing strip 12 and the transverse plate 111 in a tightly pressed state; the limit rib 125 contacts the inner step from the upper side; the unlocking rib 126 is exposed to the outside and is spaced from the limit boss 115, and the unlocking rib 126 can provide a force application point for the user to open the mopping cloth pressing strip 12.

[0024] To further press the mop, a plurality of pressing teeth 127 extending from the connecting portion 121 to the locking portion 123 are provided on the main body portion 122 of the mop pressing strip 12, and a pressing groove 116 extending from the connecting end 114 to the limiting boss 115 is provided on the transverse plate 111. When the mop is held on the mop clamping plate 1, at least part of the mop is pressed into the pressing groove 116 by being carried by the plurality of pressing teeth 127.

[0025] It can be understood that a pair of mop pressing strips 12 and a pair of transverse plates 111 provided in this embodiment together form a pair of clamping portions oppositely arranged on the front and rear sides of the cloth pressing space 113 to hold the mop on the mop clamping plate 1. In other embodiments, structures such as a pair of rollers that can tightly press the mop in the up and down directions, a magnet and a magnetic element that can clamp the mop by magnetic suction force, etc. can also be used to replace the clamping portion in this embodiment.

[0026] Continue to refer to Figure 1-4 , the mop pressing plate 2 is aligned with the cloth pressing space 113 in the up and down direction and can press the mop at the cloth pressing space 113 against the surface to be cleaned. Specifically, the mop pressing plate 2 has a first position (such as Figure 2 , Figure 6 ) in which at least part of it is received in the cloth pressing space 113 to press the mop against the surface to be cleaned and a second position (such as Figure 1 , Figure 5 ) that disengages from the cloth pressing space 113 to allow the mop clamping plate 1 to flip. The mop pressing plate 2 includes a plate body 21 facing the surface to be cleaned, a connecting seat 22 fixedly provided on the plate body 21, and a rotatable joint 23 rotatably mounted on the connecting seat 22. Among them, the rotatable joint 23 is for the user to attach a handle-shaped article.

[0027] The plate body 21 includes a bottom plate 211 defining its bottom edge, side plates 212 fixedly extending along the outer edge circumference of the bottom plate 211, and reinforcing ribs 213 fixedly provided on the inner side of the side plates 212. From the perspective in the up and down direction (i.e., Figure 3 perspective), the outer edge contour of the plate body 21 is within the range of the inner edge contour of the frame 11. When the mop pressing plate 2 is in the first position, the plate body 21 is received in the cloth pressing space 113 and the bottom plate 211 is not higher than the bottom edge of the mop clamping plate 1 to ensure that the mop contacts the surface to be cleaned; the side plates 212 of the plate body 21 are in clearance fit with the frame 11 to allow the mop at the cloth pressing space 113 to undergo adaptive deformation and movement.

[0028] Furthermore, in order to reduce the friction when the mop clamping tool 100 moves on the surface to be cleaned, a plurality of pairs of rotatable moving wheels 13 are also provided on the mop clamping plate 1. The plurality of pairs of moving wheels 13 define the bottom edge of the mop clamping plate 1, and this bottom edge is flush with the bottom plate 211 of the mop pressing plate 2.

[0029] Further, to keep the mop clamping plate 1 and the mop pressing plate 2 relatively fixed, so that when the user pulls the mop clamping tool 100 backward, the mop pressing plate 2 will not be pulled out of the cloth pressing space 113 due to the upward component force, a locking mechanism is also provided on the mop clamping tool 100. Specifically, the locking mechanism includes a pair of locking units arranged left and right. Each locking unit includes a locking hole 117 formed on the corresponding longitudinal plate 112 and an opening pin 24 fixedly arranged on the mop pressing plate 2 and adapted to the locking hole 117 (see Figure 7 ), and the opening pin 24 is located outside the plate body 21 and faces the corresponding locking hole 117. When the mop pressing plate 2 is in the first position, the opening pin 24 is inserted into the corresponding locking hole 117 to lock the mop pressing plate 2 to the mop clamping plate 1. It can be understood that in other embodiments, the locking unit can also adopt a magnetic attraction structure, a snap structure, etc. to replace the above-mentioned locking hole and opening pin.

[0030] Continue to refer to Figure 1 , the lifting mechanism provided in this embodiment includes a pair of lifting units opposite to each other left and right. Each lifting unit is a parallel four-bar linkage 3. The above-mentioned parallel four-bar linkage 3 forms a first end 31 and a second end 32 that can move back and forth relative to the first end 31 in the up and down direction. The first and second ends are respectively formed at a pair of hinge points of the parallel four-bar linkage 3 opposite to each other in the up and down direction.

[0031] The mop clamping plate 1 is rotatably connected to the first ends 31 of a pair of lifting units around the second axis Y2 extending left and right, and the mop pressing plate 2 is supported on the second ends 32 of a pair of lifting units. Further, to prevent the parallel four-bar linkage 3 from being stretched too much in the up and down direction and reaching near the dead point (that is, in this parallel four-bar linkage 3, the included angle between two adjacent linkages is close to 180°), a limiting portion 33 is provided on the first link (not shown in the figure) near the second end 32, and a limiting protrusion 34 that can contact the limiting portion 33 is provided on the second link (not shown in the figure) near the second end 32. The limiting portion 33 and the limiting protrusion 34 define the minimum included angle formed by the first and second links. The above-mentioned limiting portion 33 and the limiting protrusion 34 also simultaneously define the height of the bottom edge of the mop pressing plate 2 relative to the rotation center of the mop clamping plate 1, and this height should not be less than the maximum rotation radius of the mop clamping plate 1 to prevent the mop pressing plate 2 from interfering with the free rotation of the mop clamping plate 1. It can be understood that in other embodiments, structures such as telescopic rods, hinges, ropes, etc. can also be used to replace the parallel four-bar linkage provided in this embodiment. On the premise of ensuring that the mop pressing plate is liftably connected to the mop clamping plate and the mop clamping plate can rotate freely around the second axis, the specific structure of its lifting mechanism does not limit the protection scope of the present invention.

[0032] The working principle of the mop clamping tool 100 is described as follows: During the cleaning operation, the mop clamping plate 1 uses a pair of mop pressing strips 12 to tightly press the two end portions of the mop against the frame 11, so that the mop is held on the mop clamping plate 1; the mop pressing plate 2 is located at the first position and presses the mop in the cloth pressing space 113 against and into contact with the surface to be cleaned for the cleaning operation. After the outer surface of the mop gets dirty, the user can unlock and lift the mop pressing plate 2 upward to disengage it from the cloth pressing space 113 and switch it to the second position, and continue to lift the mop pressing plate 2 upward until the mop clamping plate 1 disengages from the surface to be cleaned; thereafter, the mop clamping plate 1 begins to flip under the action of its own weight (as Figure 5 ), and after flipping 180°, the inner and outer surfaces of the mop are switched; finally, the mop pressing plate 2 is pressed back into the first position (as Figure 6 ), so as to press the non-dirty side surface of the mop against the surface to be cleaned. Thus, the user can continue the cleaning operation on the surface to be cleaned using the mop. During this process, the user's hands do not need to contact the mop, thereby avoiding the hands being contaminated by the mop.

[0033] The above embodiments are only for illustrating the technical concept and features of the present application, and the purpose is to enable those who are familiar with this technology to understand the content of the present application and implement it accordingly, and it should not be used to limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.
