Description

Technical Field

[0001] The utility model relates to the technical field of household cleaning tools, in particular to a rolling clamping mechanism for a wiping cloth and a wiping tool. Background Art

[0002] Household cleaning tools, such as flat cloth mops with replaceable wiping cloths, table wipes, or window cleaners, can all be used for cleaning by replacing disposable wiping cloths (such as disposable non-woven fabrics, paper towels, wet wipes, etc.).

[0003] Taking the cloth mop as an example, the Chinese utility model patent with the application number CN202321208085.3 discloses a cloth mop that is convenient for replacing the mop cloth. The cloth mop includes a mop rod and a mop bottom plate; the mop bottom plate is provided with a clamping assembly for clamping the mop cloth; the clamping assembly includes a first clamping member fixed at one end of the mop bottom plate away from the mop rod, and a second clamping member movably connected to the mop bottom plate and capable of approaching or separating from the first clamping member; the mop bottom plate is further provided with a driving assembly for driving the second clamping member to approach or separate from the first clamping member; and, the mop rod is connected to the driving assembly, and by lifting or pressing down the mop rod, the driving assembly is controlled to drive the second clamping member to move closer to or away from the first clamping member. When the second clamping member approaches or separates from the first clamping member to clamp or unclamp the cloth, there may be a situation where the mop cloth fails to be successfully clamped during clamping, or there may be a situation where part of the mop cloth is not clamped, and it is easy to fall off during use, and the clamping members at both ends are prone to interfere with the ground. Summary of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] The problem to be solved by the utility model is to provide a rolling clamping mechanism for a wiping cloth and a wiping tool, which can overcome the defects in the prior art by clamping the wiping cloth in a way that the cloth-taking roller rolls.

[0006] (II) Technical Solutions

[0007] ​

[0008] In this solution, the cloth-taking roller is movably installed at the side end of the wiping main body and can rotate inward or outward. When the wiping main body is rectangular, the cloth-taking rollers are installed on both sides of the wiping main body. When the wiping main body is triangular, the cloth-taking rollers can be installed on the three side surfaces of the wiping main body; when cloth clamping is required, by rotating the cloth-taking roller, the cloth-taking roller can contact the wiping cloth and wind the wiping cloth onto the wiping main body; this solution adopts a rolling method to grab the wiping cloth, which can actively grab the wiping cloth in a winding manner, and the wiping cloth has a better wrapping effect on the wiping main body, the cloth grabbing is stable and reliable, it is not easy to fall off during use, the rotating cloth-taking roller has less impact on the flatness of the bottom surface of the wiping main body, and it is even less likely to loosen and fall off during the back-and-forth use of the wiping main body.

[0009] In some embodiments, the structure for increasing friction is arranged on the outer surface of the cloth-taking roller, and the structure for increasing friction is one or more of a rubber pad, friction patterns, Velcro, adhesive, coating, and hook claws, making the winding-type grabbing more reliable and facilitating the grabbing of a single wiping cloth. Taking some existing cloth-clamping mops as an example, when using sliding cloth-clamping plates on both sides to clamp the wiping cloth, when multiple wiping cloths are stacked together and it is necessary to clamp the topmost wiping cloth, it may clamp multiple wiping cloths, resulting in waste; therefore, this solution adopts a rolling cloth-clamping method, using the principle of a paper-taking roller in a printer to grab a single sheet of paper for printing, and grabbing a single wiping cloth through its cloth-taking roller. Therefore, it is also particularly suitable for the scenario of single-time cloth clamping and will not cause waste of wiping cloth.

[0010] In this solution, through this structure for increasing friction, it is ensured that the cloth-taking roller can grab the contacted wiping cloth onto the wiping main body; the friction patterns can be knurling structures, and the adhesive can be reusable glue.

[0011] In some embodiments, the cloth-taking roller can rotate forward and backward; when clamping the cloth, the wiping cloth is rolled and positioned on the wiping main body by the forward rotation of the cloth-taking roller; when changing the cloth, the wiping cloth is released for replacement by the reverse rotation of the cloth-taking roller; and / or, the cloth-taking rollers arranged at the side end of the wiping main body rotate in opposite directions when clamping the cloth, and the cloth-taking rollers rotate synchronously inward or synchronously outward.

[0012] In this solution, the cloth is clamped by the forward rotation of the cloth-taking roller, and the cloth clamping is released by the reverse rotation. At this time, the cloth removal operation can be performed to release the wiping cloth. The cloth-taking rollers rotate synchronously inward or synchronously outward, achieving mutual force cancellation during use, and the wiping cloth will not fall off during the back-and-forth use.

[0013] In some embodiments, there is a cloth clamping gap between the bottom plate and the cloth taking roller. The cloth taking roller rolls and positions the wiping cloth into the cloth clamping gap, so as to position the wiping cloth onto the bottom plate.

[0014] In this solution, the wiping cloth is "inserted" into the cloth clamping gap by the forward rotation of the cloth taking roller. At this time, the cloth taking roller preferably rotates inward.

[0015] In some embodiments, a side edge corresponding to the cloth taking roller is provided at the side end of the wiping main body, and the cloth clamping gap is formed between the cloth taking roller and the side edge. In this solution, the cloth taking roller grabs and positions the wiping cloth to the side edge.

[0016] In some embodiments, the cloth taking roller extends along the length or width direction of the wiping main body; and / or, the cloth taking roller is an eccentric roller.

[0017] In this solution, after grabbing the wiping cloth, the eccentric roller moves away from the ground, keeping the bottom surface of the mop flat. At the same time, it also avoids interference caused by the eccentric roller being rubbed by the surface to be cleaned.

[0018] In some embodiments, cloth clamping claws for contacting the wiping cloth are provided on the cloth taking roller. The cloth clamping claws are preferably eccentrically arranged in a conical shape.

[0019] In some embodiments, the wiping main body extends a bottom end on one side of the bottom plate, and the lower edge of the bottom end is higher than or equal to the lower edge of the side end of the bottom plate; when clamping the cloth, the cloth taking roller rotates outward synchronously, and clamps or hooks the wiping cloth to one side of the bottom end.

[0020] In this solution, the wiping cloth is grabbed to the bottom end by the forward rotation of the cloth taking roller (the rotation direction at this time is outward).

[0021] In some embodiments, specifically, the grabbed wiping cloth is positioned to the bottom end by the cloth clamping claws (it can be directly clamped and abutted, or directly hooked on the cloth clamping claws). At this time, the clamping position of the wiping cloth is at the position near the side end at the bottom of the entire wiping main body, and its bottom end is arranged outside the bottom plate. After clamping the cloth, it can wrap the bottom plate.

[0022] In another embodiment, when clamping the cloth, the cloth taking roller clamps or hooks the wiping cloth to the side end of the wiping main body.

[0023] In some embodiments, a lateral abutting portion is provided on the side end surface of the wiping main body, and the height of the lateral abutting portion is higher than that of the bottom plate. When clamping the cloth, the cloth taking roller clamps the wiping cloth to the lateral abutting portion.

[0024] In some embodiments, a floating plate for hinging the cloth taking roller is floatingly mounted on the side end of the wiping main body. A reset elastic member is mounted inside the floating plate. The floating plate is configured to be able to extend and open or retract and reset relative to the wiping main body. When switching to the cloth clamping state, the floating plate drives the cloth taking roller to retract and reset, and the cloth taking roller synchronously rotates outward, clamping and abutting the wiping cloth against the lateral abutting portion.

[0025] In this solution, the lateral abutting portion is arranged at the side end position of the wiping main body. Therefore, a part of the side end of the wiping main body will also be wrapped by the wiping cloth. When the wiping main body is placed on the surface to be cleaned, it can be ensured that the wiping cloth first contacts the surface to be cleaned, and the wiping main body will not be bumped and worn. The rotation stroke of the cloth taking roller in this solution for grasping the wiping cloth may be relatively large. During the cloth clamping process, a matching floating plate needs to cooperate with the expansion and contraction to clamp the cloth, so as to avoid pulling and damaging the wiping cloth when grasping the wiping cloth and causing the cloth clamping to fail.

[0026] In another embodiment, an avoidance cavity is provided at the side end of the wiping main body, and the cloth clamping claw directly hooks the wiping cloth into the avoidance cavity; and / or, the included angle formed by the cloth clamping claw and the bottom plate after the cloth clamping is less than or equal to 90 degrees.

[0027] In some embodiments, a driving portion for driving the cloth taking roller to rotate is provided on the wiping main body, and / or, the driving portion is a moving plate that can move relatively outward or inward. Through the telescopic movement of the moving plate, the cloth taking roller is driven to rotate.

[0028] In this solution, the driving portion can transmit power through methods such as gear-rack meshing transmission, friction transmission of friction wheels, or belt pulley transmission, so as to make the cloth taking roller rotate.

[0029] In some embodiments, a cloth taking gear is provided on the cloth taking roller, and a first rack portion meshing with the cloth taking gear is correspondingly provided on the moving plate;

[0030] Or: a cloth taking friction wheel is provided on the cloth taking roller, and a friction strip that frictionally cooperates with the cloth taking friction wheel is correspondingly provided on the moving plate; the friction strip then drives the cloth taking roller to rotate by means of rolling friction;

[0031] Or: the moving plate is hinged to the cloth taking roller through a connecting rod, and the cloth taking roller is pulled or pushed to rotate by the provided connecting rod. The hinge axis of the connecting rod and the cloth taking roller is eccentrically arranged.

[0032] In some embodiments, a driving part for driving the cloth-taking roller to rotate is provided on the wiping main body. A cloth-taking gear is arranged on the cloth-taking roller, and the driving part is a multi-stage gear set meshed with the cloth-taking gear. In this solution, power is directly transmitted to the cloth-taking roller through the meshing of the multi-stage gear set to make it rotate, without transmitting power to the cloth-taking roller in the way of moving the moving plate.

[0033] In some embodiments, the wiping main body is further provided with a linkage part for controlling the movement of the driving part. Through the movement (translation or rotation) of the linkage part, the driving part is driven to rotate the cloth-taking roller.

[0034] In one of the embodiments, the linkage part is rotatable, and the linkage part is a transmission gear meshed with the moving plate gear;

[0035] Or, the linkage part is an eccentric cam. The moving plate is provided with a camshaft, and the eccentric cam is provided with a cam groove matched with the camshaft;

[0036] Or, the linkage part is an eccentric crankshaft. Through the swing of the eccentric crankshaft, the moving plate is pushed to move.

[0037] In some embodiments, when the linkage part is an eccentric crankshaft, the moving plate is connected to the eccentric crankshaft through a slidable sliding plate, and the sliding plate reciprocates along the length direction of the wiping main body; a swing groove matched with the eccentric crankshaft is arranged on the sliding plate, a matching shaft is arranged on the moving plate, and an inclined sliding groove slidably matched with the matching shaft is arranged on the sliding plate.

[0038] In some embodiments, the bottom plate is installed on the wiping main body. A raised part is formed by the middle of the wiping main body bulging outwards. The raised part is configured to deform when the bottom plate contacts the ground, so that the wiping cloth can better fit the surface to be cleaned; and / or, the bottom plate is made of soft plastic or foam; and / or, the wiping cloth is a disposable non-woven fabric or paper towel.

[0039] In some embodiments, a lock is further provided on the wiping main body. The lock is configured to prevent the cloth-taking roller from rotating when the cloth is clamped or during wiping use. The lock can be arranged on one side of the cloth-taking roller, or on one side of the driving part or the linkage part. When the cloth is clamped or during wiping use, the cloth-taking roller can be prevented from rotating through this lock.

[0040] In some embodiments, the gripping portion is an operating lever; the operating lever is in transmission connection with the linkage member, and the linkage member moves by the up and down movement of the operating lever along the axis. In this embodiment, the operating lever can drive the linkage member to rotate via a twisted rod structure, and then transmit power to the drive unit to rotate the cloth taking roller.

[0041] In some embodiments, the lock includes a buckle connected to the operating rod and a buckle platform that is transmission-connected to the linkage part; when the cloth is clamped or wiped, the buckle is engaged with the buckle platform to form a self-locking function, so that the cloth-taking roller remains in the cloth-clamping state, so that the wiping cloth will not fall off during wiping and cleaning.

[0042] In some embodiments, the operating rod includes an inner rod and an outer rod slidably connected to each other, the outer rod is hinged to the wiping body through a universal joint, and the inner rod is transmission-connected to the linkage.

[0043] In some embodiments, the universal joint is provided with a positioning pin configured to maintain the operating rod and the wiping body in a perpendicular position; and / or the wiping body is provided with a positioning pin slot corresponding to the positioning pin. In this embodiment, the positioning pin allows the operating rod and the wiping body to maintain a perpendicular position (in which case cloth clamping, removing, or replacing cloth can be performed).

[0044] In some embodiments, the inner rod is connected to a twisted rod, and the twisted rod is hinged to the linkage part through an inner cross hinge shaft; the inner rod is moved up and down along the axis direction, driving the twisted rod to rotate and driving the linkage part to move relative to each other through the inner cross hinge shaft; and / or, the buckle is arranged at the lower end of the inner rod, and the buckle platform is arranged on the twisted rod, and when the cloth is clamped or wiped, the buckle is engaged with the buckle platform.

[0045] In this solution, the up and down movement of the inner rod drives the twisted rod to rotate, thereby driving the linkage member to rotate.

[0046] In some embodiments, the linkage member is exposed on the wiping body, and the driving part and the cloth taking roller are driven to move by directly triggering the linkage member (which can be triggered and driven by rotating, pushing, pulling, or toggling).

[0047] In some embodiments, the linkage includes an adjustment portion and a gear portion drivingly connected to the movable plate. A user can directly contact the adjustment portion to control the rotation of the cloth-taking roller. External force applied to the adjustment portion causes the movable plate to telescope, thereby rotating the cloth-taking roller. The external force can be applied manually or by foot. For example, the adjustment portion can be manually rotated to achieve switching, or the adjustment portion can be manually moved to achieve switching control.

[0048] In some embodiments, the linkage is arranged to rotate along the vertical axis, and the linkage is respectively engaged with the front and rear movable plate gears, and the cloth taking roller is rotated by rotating the adjustment part, in which case the adjustment part is a knob structure. In addition, a lock can be provided between the adjustment part and the wiping body.

[0049] In some embodiments, the linkage is rotatable along the horizontal axis, the gear portion meshes with the gear of the movable plate on one side, and the gear portion meshes with the gear of the movable plate on the other side via a connecting gear, and the cloth-taking roller is rotated by turning the adjustment portion. In this case, the adjustment portion is a toggle structure, which can be directly set as a protruding lever or a knurled push button structure.

[0050] An embodiment of this specification further provides a wiping tool, which is implemented based on the rolling clamping mechanism of the wiping cloth described in any embodiment of this specification. The wiping tool is a flat mop, and the wiping body is a mop head.

[0051] An embodiment of the present specification further provides a wiping tool, which is implemented based on the rolling clamping mechanism of the wiping cloth described in any embodiment of the present specification, and the wiping tool is a window wiper.

[0052] The embodiments of this specification also provide a wiping tool, which is implemented based on the rolling clamping mechanism of the wiping cloth described in any embodiment of this specification, and the wiping tool is a desktop eraser or a blackboard eraser.

[0111] The following describes the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

[0112] Refer to Figures 1 to 49 , the present utility model provides a rolling clamping mechanism for a wiping cloth, including a wiping main body 1 that can be used to install the wiping cloth and a holding part connected to the wiping main body 1. The wiping main body 1 includes a bottom plate 101 that contacts the wiping cloth. When cleaning, hold the holding part with the hand and clean the surface to be cleaned (such as the ground, glass, wall, tabletop, etc.). At least two side ends of the wiping main body 1 are rotatably connected with cloth-taking rollers 2. In the embodiments of this specification, the cloth-taking rollers 2 are rotatably installed in the installation cavities with openings at the side ends of the wiping main body 1. The cloth-taking rollers 2 grab the wiping cloth through the openings. When clamping the cloth, at least part of the cloth-taking rollers 2 are exposed outside the wiping main body 1. The cloth-taking rollers 2 are provided with structures for increasing friction, so as to facilitate the cloth-taking rollers 2 to roll and grab the wiping cloth. When clamping the cloth, place the wiping main body 1 on the wiping cloth. By rotating the cloth-taking rollers 2 inward or outward, the cloth-taking rollers 2 contact the wiping cloth, and the contacted wiping cloth is rolled and positioned on the wiping main body 1, and the wiping cloth covers the bottom plate 101.

[0113] It should be noted that the embodiments of this specification do not further limit the shape of the wiping main body 1. It can be rectangular or triangular, etc. When the wiping main body 1 is rectangular, the cloth-taking rollers 2 are arranged along the length or width direction of the wiping main body 1, preferably the length direction. When the wiping main body 1 is triangular, the cloth-taking rollers 2 are arranged on the three side ends of the wiping main body 1 (in this case, the cloth-taking rollers 2 preferably rotate outward). The wiping main body 1 in the embodiments of this specification is only taken as an example of a rectangle.

[0114] Among them, the cloth-taking rollers 2 can rotate forward and backward. When clamping the cloth, the wiping cloth is rolled and positioned on the wiping main body 1 by rotating the cloth-taking rollers 2 forward. When changing the cloth, the wiping cloth is released by rotating the cloth-taking rollers 2 backward for replacement. By rotating the cloth-taking rollers 2 forward to clamp the cloth and backward to release the clamping, the cloth can be removed at this time, and the wiping cloth is released. The cloth removal operation can be performed by hand or foot to separate the wiping cloth from the wiping main body 1.

[0115] The clamping mechanism in this specification realizes the grasping of the wiping cloth by the forward or reverse rotation of the cloth-taking roller 2. When it is necessary to clamp the cloth, the cloth-taking roller 2 can contact the wiping cloth, and through the rotation of the cloth-taking roller 2, the wiping cloth is wound onto the wiping main body 1; the wiping cloth can be disposable non-woven fabric, household paper towels, wet wipes, etc. Of course, the wiping cloth can also be reused, as long as it can be grasped by the cloth-taking roller 2 onto the wiping main body when rolling to clamp the cloth; the wiping cloth is preferably disposable non-woven fabric.

[0116] It should be noted that in the embodiment of this specification, the wiping cloth is grasped and positioned by the rolling of the cloth-taking roller 2, and the grasping method is novel and reliable; at the same time, by using the method of the cloth-taking roller 2 rolling to grasp the wiping cloth, it can be ensured that a single wiping cloth can be grasped when clamping the cloth; when the wiping cloth is stacked in the storage box, at this time, the rolling cloth-grasping method (the cloth-grasping principle of the cloth-taking roller 2 is similar to the principle of the paper-taking roller of a printer grasping paper for single-sheet printing) is adopted to ensure that a single wiping cloth can be grasped.

[0117] In some embodiments, the structure for increasing friction is directly arranged on the outer surface of the cloth-taking roller 2. The cloth-taking roller 2 grasps the wiping cloth through the structure for increasing friction, and the structure for increasing friction is one or more of a rubber pad (such as silica gel), friction patterns (as Figure 37 shown, the structure for increasing friction is a knurling structure directly arranged on the surface of the cloth-taking roller 2), Velcro, adhesive, coating (such as a matte coating that can increase friction), and hook claws. Of course, it should be noted that the structure for increasing friction can also be directly arranged on a specific wiping cloth, and the structure for increasing friction is preferably arranged on the cloth-taking roller 2.

[0118] In this solution, through this structure for increasing friction, it is ensured that the cloth-taking roller 2 can grasp the contacted wiping cloth onto the wiping main body 1; the rubber pad can be, for example, a silica gel structure; the friction pattern can be a knurling structure, and the adhesive can be a reusable glue (which can be directly purchased and will not be elaborated in this specification).

[0119] When the cloth clamping is completed, the cloth-taking roller 2 can rotate and abut the wiping cloth against the wiping body 1, or the wiping cloth can be directly rotated and hooked on the Velcro, adhesive, or hook claws of the cloth-taking roller 2 through the hook claws. The cloth-taking rollers 2 arranged at the side ends of the wiping main body 1 rotate in opposite directions when clamping the cloth, and the cloth-taking rollers 2 rotate synchronously towards the inside or synchronously towards the outside.

[0120] In some embodiments, such as Figure 3 and Figure 4As shown, taking a flat mop as an example, there is a cloth clamping gap between the bottom plate 101 and the cloth taking roller 2. The cloth taking roller 2 rolls and positions the wiping cloth into the cloth clamping gap, so that the wiping cloth is positioned on the bottom plate 101. At this time, the cloth clamping gap can also play a role in positioning and clamping the wiping cloth. The cloth taking roller 2 rotates inward (as Figure 4 shown, the forward direction at this time is the direction of rotating inward) to grab the wiping cloth; the state of completing cloth clamping is that the outer end part of the wiping cloth is wound and "inserted" into the cloth clamping gap by the cloth taking roller 2 (the wiping cloth is folded into the cloth clamping gap, and it is very difficult to pull it out of the cloth clamping gap by directly pulling the wiping cloth at this time). When the wiping cloth is ordinary paper, it is especially suitable for the cloth clamping method of the cloth taking roller 2 rotating inward. In addition, when the structure for increasing friction adopts structures such as silica gel, knurling, and coating, it is especially suitable for the situation where the cloth taking roller 2 rolls inward to clamp the cloth.

[0121] As Figure 3 and Figure 4 shown, a side edge 102 corresponding to the cloth taking roller 2 is provided at the side end of the wiping main body 1. A cloth clamping gap is formed between the cloth taking roller 2 and the side edge 102. In this embodiment, the cloth taking roller 2 grabs the wiping cloth and "inserts" it into the side edge 102. For example, through structures such as rubber pads or friction patterns on the cloth taking roller 2 to increase friction, the wiping cloth is sent into the cloth clamping gap when clamping the cloth, and when releasing the cloth, the wiping cloth is sent out of the cloth clamping gap by the reverse rotation of the cloth taking roller 2.

[0122] As Figure 3 and Figure 4 shown, the included angle between the side edge 102 and its bottom plate 101 is an acute angle.

[0123] In one example, as Figure 11 shown, a cloth clamping claw 202 (which is a kind of hook claw) is provided on the cloth taking roller 2; when waiting to clamp the cloth, the cloth clamping claw 202 faces the wiping cloth side. At this time, the lower edge of the cloth clamping claw 202 can be lower than or equal to the lower edge of the side end of the bottom plate 101. Preferably, the lower edge of the cloth clamping claw 202 is lower than the lower edge of the side end of the bottom plate 101 (to ensure that when the wiping main body 1 is placed on the wiping cloth, through the rotation of the cloth taking roller 2, it can be ensured that the cloth clamping claw 202 contacts the wiping cloth). Of course, it should be noted that when the lower edge of the cloth clamping claw 202 is higher than the lower edge of the side end of the bottom plate 101, cloth clamping can still be completed; taking a relatively thick non-woven fabric as the wiping cloth as an example, when the bottom plate 101 of the wiping main body 1 contacts and presses down on the wiping cloth, the outer wiping cloth will be grabbed and positioned on the wiping main body 1 by the rolling cloth taking roller 2 due to partial upward warping, and the function of rolling and grabbing the cloth can still be realized; of course, in actual use, preferably, the use effect is the best when the lower edge of the cloth clamping claw 202 is lower than the lower edge of the side end of the bottom plate 101.

[0124] As Figure 11 shown, the cloth clamping claw 202 is preferably an eccentrically arranged conical shape.

[0125] In some preferred embodiments, Figure 11 As shown, the cloth taking roller 2 is an eccentric roller.

[0126] In some embodiments, as Figure 10 and Figure 14 As shown, the wiping body 1 is provided with a bottom end 103 extending from one side of the base plate 101. The lower edge of the bottom end 103 is higher than or equal to the lower edge of the side end of the base plate 101. When clamping the cloth, the cloth pick-up roller 2 rotates outward synchronously to grab the wiping cloth to the side of the lower edge of the bottom end 103. The wiping cloth can be directly positioned against the bottom end 103, or it can be directly hooked on the cloth pick-up roller 2 by the cloth clamping claws 202 or Velcro on the cloth pick-up roller 2, thereby positioning the wiping cloth on the wiping body 1 (i.e., in this case, the wiping cloth does not need to contact the bottom end 103).

[0127] like Figure 14 As shown, the bottom end 103 is a narrow side, and the lower edge height of the bottom end 103 is preferably higher than the bottom plate 101, so that the bottom end 103 will not be bumped during mopping. The wiping cloth is clamped to the bottom end 103 by the cloth clamping claws 202. At this time, the positive direction is the direction of rotation toward the outside. When clamping the cloth, the cloth clamping claws 202 rotate outward to abut the wiping cloth against the bottom end 103; as shown in FIG. Figure 14 As shown, Figure 14 That is a structural diagram of the wiping cloth being grabbed by the cloth-taking roller 2 to the bottom end 103 , and the wiping cloth after being clamped wraps around the bottom plate 101 .

[0128] In one embodiment, when clamping the cloth, the cloth-taking roller 2 clamps or hooks the wiping cloth to the side end of the wiping body 1 .

[0129] like Figures 17 - 25 As shown, a lateral abutment 104 is provided on the side end surface of the wiping body 1. The height of the lateral abutment 104 is higher than the bottom plate 101. When clamping the cloth, the cloth-taking roller 2 clamps the wiping cloth and abuts against the lateral abutment 104. In this embodiment, the cloth-taking roller 2 grabs the wiping cloth by means of the cloth-clamping claws 202.

[0130] In a preferred embodiment, considering that the rotation stroke of the cloth-taking roller 2 rolling outward to grab the wiping cloth may be large, Figures 22 - 24 As shown, a floating plate 3 for articulating the cloth-taking roller 2 is floatingly mounted on the side end of the wiping body 1. A reset elastic member 4 is mounted on the inner side of the floating plate 3. The floating plate 3 is configured to extend outward or retract inward relative to the wiping body 1. When switched to the cloth-clamping state, the floating plate 3 drives the cloth-taking roller 2 to retract and reset, and the cloth-taking roller 2 simultaneously rotates outward, clamping the wiping cloth against the lateral abutment portion 104. At this time, the forward direction is the direction of rotation outward.

[0131] The lateral abutting portion 104 is arranged at the side end position of the wiping main body 1. Therefore, a part of the side end of the wiping main body 1 is also wrapped by the wiping cloth. When the wiping main body 1 is placed on the ground, it can ensure that the wiping cloth first contacts the ground, and the wiping main body 1 will not be knocked and worn.

[0132] It should be noted that in this embodiment, through the matching floating plate 3, the wiping cloth is clamped by rolling in combination with the retraction movement of the floating plate 3 during the cloth clamping process, so as to avoid pulling and damaging the wiping cloth (such as when the wiping cloth is ordinary tissue paper) when grasping the wiping cloth, resulting in the failure of cloth clamping. As Figure 23 and Figure 24 shown, the rotation stroke of the cloth taking roller 2 may be relatively large. If the wiping cloth is directly grasped by a structure such as the cloth clamping claw 202 that increases the friction force, its rotation stroke is greater than the deformable amount of the wiping cloth, resulting in the wiping cloth being pulled and damaged or separated from the cloth taking roller 2. Therefore, the floating plate 3 can be preferably used to cooperate with the cloth taking roller 2 for rolling cloth clamping. At the same time, it should be noted that not all the cloth taking rollers 2 that rotate outward need to be provided with a movable floating plate 3. The setting of the floating plate 3 is a preferred setting method.

[0133] In another embodiment, as Figure 25 and Figure 36 shown, an avoidance cavity 105 is arranged on the side end of the wiping main body 1, and the cloth clamping claw 202 directly hooks the wiping cloth into the avoidance cavity 105; as Figure 27 shown, the included angle formed by the cloth clamping claw 202 and the bottom plate 101 after cloth clamping is less than or equal to 90 degrees. At this time, the wiping cloth is hooked by the cloth clamping claw 202 in the avoidance cavity 105. It should be noted that the cloth clamping claw 202 of the cloth taking roller 2 can also be realized by a structure such as Velcro that increases the friction force.

[0134] In some embodiments, the bottom plate 101 is installed on the wiping main body 1, and a raised portion is formed by the middle of the wiping main body 1 bulging outward. The raised portion is configured to deform when the bottom plate 101 contacts the ground, so that the wiping cloth can better fit the surface to be cleaned; the bottom plate 101 is made of soft plastic or foam. As Figure 36 shown, the bottom plate 101 is preferably buckled on the wiping main body 1.

[0135] In some embodiments, a driving portion for driving the cloth taking roller 2 to rotate is provided on the wiping main body 1.

[0136] Specifically, as Figure 7 、 Figure 13 、 Figure 21 、 Figure 26 、 Figure 28 、 Figure 32 、 Figure 37 、 Figure 41As shown, the driving part can be a moving plate 5 that can move relatively outward or inward. By the telescopic movement of the moving plate 5, the cloth-taking roller 2 is driven to rotate. In some embodiments, such as Figure 7 , Figure 13 , Figure 21 and Figure 26 shown, the moving plate 5 is driven by a gear-rack structure. A cloth-taking gear 201 is provided on the cloth-taking roller 2, and a first rack portion 501 that meshes with the cloth-taking gear 201 is correspondingly provided on the moving plate 5.

[0137] In some embodiments, such as Figure 28 , Figure 30 , Figure 32 and Figure 34 shown, the moving plate 5 is hingedly connected to the cloth-taking roller 2 through a connecting rod 503. The cloth-taking roller 2 is pushed or pulled by the connecting rod 503 to rotate, and the hinge point of the connecting rod 503 and the cloth-taking roller 2 is eccentrically arranged.

[0138] In addition, the cloth-taking roller 2 can also be drivingly connected to the moving plate 5 through a friction wheel structure. A cloth-taking friction wheel is provided on the cloth-taking roller 2, and a friction strip that frictionally cooperates with the cloth-taking friction wheel is correspondingly provided on the moving plate 5. The cloth-taking friction wheel is driven to roll by the friction strip.

[0139] It should be noted that the driving part can also rotate the cloth-taking roller 2 by other means such as belt drive.

[0140] In some other embodiments, a driving part for driving the cloth-taking roller 2 to rotate is provided on the wiping main body 1. A cloth-taking gear 201 is provided on the cloth-taking roller 2, and the driving part is a multi-stage gear set that meshes with the cloth-taking gear 201, that is, the driving part directly transmits power to the cloth-taking roller 2 by means of meshing of the multi-stage gear set.

[0141] In some embodiments, the wiping main body 1 is further provided with a linkage member 7 for controlling the movement of the driving part. By the movement (which can be movement or rotation) of the linkage member 7, the driving part is driven to rotate the cloth-taking roller 2.

[0142] In one embodiment, the linkage member 7 is rotatable. As shown in Figure 7 , Figure 13 , Figure 21 , Figure 26 shown, the linkage member 7 is a transmission gear that meshes with the moving plate 5. The telescopic movement of the moving plate 5 is realized through the meshing transmission of the gear and the rack; as shown in Figure 6 and Figure 12 shown, the moving plate 5 is provided with a second rack portion 502 that meshes with the moving plate 5.

[0143] In another embodiment, as shown in Figure 28 , Figure 30 , Figure 31 ,Figure 39 and Figure 40 As shown, the linkage member 7 is a rotatable eccentric cam, the movable plate 5 is provided with a cam shaft 504, and the eccentric cam is provided with a cam groove 701 that cooperates with the cam shaft 504. Of course, it should be pointed out that the cam shaft 504 can also be provided on the eccentric cam, and the cam groove 701 is provided on the movable plate 5.

[0144] In another embodiment, Figure 34 and Figure 43 As shown, the linkage member 7 is an eccentric crank shaft 702 , and the eccentric crank shaft 702 is swung to push the moving plate 5 to move.

[0145] In one example, the movable plate 5 is directly provided with a waist-shaped groove that cooperates with the eccentric crank shaft 702. The waist-shaped groove is arranged along the length direction of the wiping body 1, so that the eccentric crank shaft 702 and the movable plate 5 directly form a crank slider mechanism (not shown in the drawings of this specification), and the telescopic movement of the two movable plates 5 is realized by rotating the linkage part 7.

[0146] In another example, Figure 34 、 Figure 35 、 Figure 41 and Figure 43 As shown, the movable plate 5 is connected to the eccentric crank shaft 702 via a slidable sliding plate 11, and the sliding plate 11 reciprocates along the length direction of the wiping body 1. The sliding plate 11 is provided with a swinging groove 1101 that cooperates with the eccentric crank shaft 702. The movable plate 5 is provided with a matching shaft 505, and the sliding plate 11 is provided with an oblique groove 1102 that slidably cooperates with the matching shaft 505. The sliding direction of the sliding plate 11 is parallel to the length direction of the wiping body 1, while the telescopic movement direction of the movable plate 5 is parallel to the width direction of the wiping body 1. Therefore, the sliding direction of the sliding plate 11 is perpendicular to the movement direction of the movable plate.

[0147] It should be noted that the driving portion of the clamping mechanism of this specification can drive the cloth taking roller 2 in a variety of ways, and its linkage member 7 can also achieve telescopic movement of the movable plate 5 in a variety of ways, thereby realizing the rotation of the cloth taking roller 2.

[0148] In some embodiments, as Figure 1 As shown, the gripping portion is an operating lever 6; the operating lever 6 is transmission-connected to a linkage member 7, and the linkage member 7 is rotated by the up-and-down movement of the operating lever 6 along the axial direction; this embodiment is mainly suitable for flat mops, and can also be applied to tools such as window cleaners and desktop cleaners.

[0149] In some embodiments, see Figures 1 - 4The operating rod 6 includes an inner rod 601 and an outer rod 10 that can be slidably connected to each other. The outer rod 10 is hinged to the wiping body 1 through a universal joint 12 (also known as an outer cross hinge shaft), and the inner rod 601 is transmission-connected to the linkage member 7.

[0150] See Figure 3 and Figure 4 The inner rod 601 is connected to the twisted rod 8, which is hinged to the linkage member 7 through the inner cross hinge shaft 9; the inner rod 601 moves up and down along the axis, driving the twisted rod 8 to rotate and driving the linkage member 7 to move relative to each other through the inner cross hinge shaft 9.

[0151] In some embodiments, as Figure 1 and Figure 8 As shown, the universal joint 12 is provided with a positioning pin 1201, which is configured to keep the operating rod 6 and the wiping body 1 in a vertical state (this state can be used for cloth changing operation and is suitable for a structure that is driven by a twisted rod, etc.); Figure 8 As shown, the wiping body 1 is provided with a positioning pin groove 106 corresponding to the positioning pin 1201. Figure 1 As shown, the outer rod 10 is also provided with a positioning pin structure having the same principle as the positioning pin 1201.

[0152] In some embodiments, a lock buckle is further provided on the wiping body 1, and the lock buckle is configured to lock the cloth taking roller 2 so that it does not rotate when the cloth is clamped or when it is used for wiping.

[0153] In some embodiments, as Figure 3 and Figure 4 As shown, the lock comprises a buckle 602 connected to the operating rod 6 and a buckle platform 801 connected to the linkage member 7; when the cloth is clamped or wiped, the buckle 602 and the buckle platform 801 are buckled together to form a self-locking, Figure 4 This is a schematic diagram of the structure after the buckle teeth 602 and the buckle platform 801 are buckled together.

[0154] Specific as Figure 2 、 Figure 3 、 Figure 4 and Figure 8 As shown, in one example, the buckle teeth 602 of the lock are set at the lower end of the inner rod 601, and the buckle platform 801 is set on the twisted rod 8. When the cloth is clamped or wiped, the buckle teeth 602 are engaged with the buckle platform 801 to form a certain self-locking (such as Figure 2 and Figure 4As shown). At this point, the inner rod 601 cannot be pulled upward at will. Only by overcoming the engagement force between the clasp teeth 602 and the clasp platform 801 can the inner rod 601 continue to move upward for operation (for example, if the inner rod 601 and the outer rod 10 are held separately with both hands, the inner rod 601 can only move upward relative to the outer rod 10 by overcoming the self-locking engagement force of the lock). Therefore, the lock achieves self-locking through the structure of the clasp teeth 602 cooperating with the clasp platform 801 of the twisted rod 8, keeping the cloth-removing roller in a cloth-holding state, so that the wiping cloth will not fall off during wiping and cleaning.

[0155] In some embodiments, as Figure 44 and Figure 47 As shown, the linkage member 7 is directly exposed on the wiping body 1, and the driving part and the cloth taking roller 2 are driven to move by directly triggering the linkage member 7.

[0156] In some embodiments, as Figures 45 - 49 As shown, the linkage member 7 includes an adjustment portion 703 and a gear portion 704 that is transmission-connected to the movable plate 5. The user can directly contact the adjustment portion 703 to control the rotation of the cloth-taking roller 2, for example, by triggering the control by rotating, pushing, pulling, or toggling.

[0157] In one example, Figure 45 and Figure 46 As shown, the linkage member 7 is rotatably arranged along the vertical axis direction, and the linkage member 7 is respectively engaged with the gears of the front and rear movable plates 5 , and the cloth taking roller 2 is rotated by rotating the adjustment part 703 .

[0158] In another example, Figure 48 and Figure 49 As shown, the linkage member 7 is arranged to rotate along the horizontal axis, the gear portion 704 is engaged with the gear of the movable plate 5 on one side, and the gear portion 704 is engaged with the gear of the movable plate 5 on the other side through the connecting gear 13. The cloth taking roller 2 is rotated by toggling the adjustment portion 703 back and forth.

[0159] It should be pointed out that the lock can be set between the adjustment part 703 and the wiping body 1. When the adjustment part 703 of the linkage part is rotated or moved to the position where the cloth is clamped, it is positioned on the wiping body 1 through the lock to prevent the cloth taking roller 2 from rotating further.

[0160] Based on the same inventive concept, embodiments of this specification also provide a wiping tool, implemented using any of the aforementioned clamping mechanisms, wherein the wiping tool is a flat mop, the surface to be cleaned can be a floor, the wiping body 1 is a mop head, and the inner rod 601 is a mop handle. The flat mop preferably employs a relatively slidable inner rod 601 and outer rod 10, with the twisted rod 8 structure driving the linkage member 7 to move, thereby achieving rotation of the cloth-taking roller 2.

[0161] Based on the same inventive concept, an embodiment of this specification further provides a wiping tool, which is implemented based on the clamping mechanism described in any one of the foregoing. The wiping tool is a window wiper, and the surface to be cleaned can be a window, a ceramic tile wall surface, etc.

[0162] Based on the same inventive concept, an embodiment of this specification further provides a wiping tool, which is implemented based on the clamping mechanism described in any one of the foregoing. The wiping tool is a tabletop wiper or a blackboard eraser, the holding part can be a handle, the surface to be cleaned can be a tabletop or a blackboard, and the driving of the cloth-taking roller can be realized by manually contacting and controlling the adjusting part 703 of the driving part 7. It should be noted that when the wiping tool is a tabletop wiper or a blackboard eraser, the structures such as the operating rod 6 and the twist rod 8 can also be used to realize the rotational driving of the cloth-taking roller 2.

[0163] For the same and similar parts among the various embodiments in this specification, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

[0164] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in this application should be covered by the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
