Description

Technical Field

[0001] The utility model relates to the technical field of cleaning products, in particular to a mopping device. Background Art

[0002] A mopping device is a device with a cleaning cloth, such as a mop or the like, for cleaning. Specifically, a Chinese patent with publication number CN212415649U discloses a mopping device, which clamps and releases a sheet-like cleaning member by providing a clamping unit in the width direction of a substrate and driving and controlling the clamping and releasing unit.

[0003] However, the movement direction of the driving unit is set to the width direction of the substrate, so the clamping force is output at only a fixed point. At this time, if the length of the substrate involved is short, there will be no effect. However, if the length of the substrate is long, because the clamping force output position is only one point, the clamping unit is far away from the clamping force output point, the elastic deformation of the clamping unit will cause insufficient clamping force, which may easily cause the sheet cleaning element to detach from the clamping unit. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a dragging and wiping device, which solves the technical problem of insufficient clamping force in the prior dragging and wiping device.

[0005] According to an embodiment of the present utility model, a mopping device is described, comprising:

[0006] Clamping mechanism: The clamping mechanism comprises symmetrically arranged clamping blocks, and the two clamping blocks can move towards and away from each other;

[0007] Driving mechanism: the driving mechanism is connected with a plurality of reversing structures, the reversing structures are connected with the clamping blocks, the driving mechanism can drive the reversing structures to move in a direction perpendicular to the moving direction of the clamping blocks, and the reversing structures can drive the two clamping blocks to move closer to or away from each other;

[0008] Base plate: the clamping mechanism and the driving mechanism are both movably mounted on the base plate, a sheet-like cleaning member is mounted on the lower side of the base plate, and the two clamping blocks respectively cooperate with the two side edges of the base plate to clamp the sheet-like cleaning member.

[0009] The technical principle of the utility model is: the driving mechanism drives the reversing structure to move in a direction perpendicular to the moving direction of the clamping block, that is, the length direction of the substrate. The reversing structure drives the clamping blocks to move closer or farther from each other during movement, thereby clamping or releasing the sheet-like cleaning member.

[0010] Because there are multiple commutation structures, even if the substrate and the clamping block are long, more commutation structures can be set, and each commutation structure is equivalent to an output point of clamping force; at the same time, because the driving mechanism drives the commutation structure to move in the length direction of the substrate, multiple commutation structures can be set.

The two side edges of the clamping block 101 are inserted into the guide grooves 311, that is, the clamping block 101 is movably installed on the substrate 300, allowing the clamping block 101 to move along the length direction of the guide grooves 311.

[0063] like Figure 1-2As shown, the driving mechanism 200 includes a lower pressing block 210 and two moving blocks 220, wherein the lower pressing block 210 is vertically arranged at the center of the substrate 300, and the two moving blocks 220 are respectively arranged on both sides of the lower pressing block 210, and the lower pressing block 210 and one moving block 220 are both provided with inclined surfaces 201, and the two inclined surfaces 201 are tightly matched with each other, and the moving block 220 is evenly provided with an integrally formed reversing structure on both sides close to the clamping block 101, and the reversing structure on one side is connected to the clamping block 101 on the same side, and the lower pressing block 210 can drive the moving block 220 and the reversing structure to move in a direction perpendicular to the moving direction of the clamping block 101, and the reversing structure can drive the two clamping blocks 101 to move closer to and away from each other to realize the clamping function, and the specific inclined surface 201 of the lower pressing block 210 can be an inclined surface or an arc surface, and the inclined surface 201 of the moving block 220 is an inclined surface.

The connecting block 230 is located on the upper side of the pressing block 210, and the connecting block 230 can move along the length direction of the vertical groove 323 to press the pressing block 210, and then the operator applies downward pressure to the pipe fitting 231, so that the pressing block 210 can move downward to drive the moving block 220.

[0066] like Figure 1 , 3As shown, the reversing structure is a tilting rod 240, which is tilted to the moving direction of the clamping block 101. The tilting rods 240 on both sides of the moving block 220 are symmetrically arranged. The clamping block 101 is provided with a tilting groove 120, and the tilting rod 240 is inserted into the tilting groove 120. Specifically, a roller 241 is provided on the top of the tilting rod 240, and the roller 241 is arranged in the tilting groove 120. The roller 241 can roll along the tilting groove 120, so that the tilting rod 20 drives the clamping block 101 to move more smoothly; the clamping block 101 and A sliding structure 130 is provided between the substrates 300, and the sliding direction of the sliding structure 130 is the moving direction of the clamping block 101.

[0067] like Figure 1 , 5 As shown, the clamping block 101 is provided with a plurality of slots 140, which extend to one side of the clamping block 101 away from the clamping sheet cleaning member 301. An auxiliary guide protrusion 330 is integrally formed at the position corresponding to the slot 140 on the substrate 300. The auxiliary guide protrusion 330 is inserted into the slot 140. The slot 140 is also integrally formed with a raised edge 141. A groove 331 is provided on the auxiliary guide protrusion 330, which is inserted into the groove 331. The clamping block 101 moves along the length direction of the groove 331, that is, the moving direction of the clamping block 101. The auxiliary guide protrusion 330, the sliding structure 130 and the guide protrusion 310 cooperate to further improve the stability of the moving trajectory of the clamping block 101.

[0068] The auxiliary guide protrusion 330 is fixed to the limiting channel 320 , which is equivalent to adding a structure similar to a reinforcing rib to the limiting channel 320 , thereby improving the strength of the limiting channel 320 .

[0069] like Figure 1-2As shown, the moving block 220 is integrally formed with an inclined tooth 221, and the inclined tooth 221 of the moving block 220 is inclined toward the side of the pressing block 210. The inclined tooth 221 is connected to the limiting mechanism 400, and the limiting mechanism 400 can clamp the moving block 220 and prevent it from moving toward the side of the pressing block 210. The moving block 220 is provided with an elastic member 202 at one end of the moving block 220, and the substrate 300 is integrally formed with a blocking piece 30 at the elastic member 202 at one end of the moving block 220. 3, so that the elastic member 202 at one end of the moving block 220 is stuck between the blocking piece 303 and the moving block 220, ensuring that the elastic member 202 can press the moving block 220 to move to the side of the pressing block 210, and an elastic member 202 is also provided between the pressing block 210 and the base plate 300, that is, the two elastic members 202 are used for the clamping block 101 to release the sheet-like cleaning member 301, and the limiting mechanism 400 allows the clamping block 101 to keep clamping the sheet-like cleaning member 301.

[0071] In practical applications, the length of the substrate 300 and the clamping block 101 does not need to be increased without increasing the number of the limiting mechanisms 400. It is only necessary to increase the number of the reversing structures by the same amount to ensure the clamping force. As a result, the increase in length will not make the overall structure too complicated.

[0072] like Figure 1-2As shown in , 6, mounting columns 340 are integrally formed at both ends of the limiting channel 320. The interior of the mounting column 340 is hollow and communicates with the limiting channel 320. The limiting block 410 is installed inside the mounting column 340.

The limiting edge 322 and the mounting column 340 are both inserted into the receiving cover 510. Matching holes 511 are provided on both sides of the receiving cover 510. The opening and closing block 420 is installed in the matching holes 511, so that the opening and closing block 420 can only move within the length range of the movable groove 324. A channel structure 512 is provided in the middle of the receiving cover 510. The channel structure 512 is used to connect the connecting block 230 with the pipe fitting 231, so that the connecting block 230 can only move within the length range of the vertical groove 323. The upper cover 500 and the base plate 300 are also connected and fixed at the sliding structure 130 by positioning screws 131.

[0074] Example 2

[0075] like Figure 7 As shown, the difference between this embodiment and embodiment 1 is that: the two moving blocks 220 are both provided with an inclined surface 201, and the lower pressing block 210 is provided with two inclined surfaces 201, and the inclined surfaces 201 of the two moving blocks 220 are respectively tightly matched with the two inclined surfaces 201 on the lower pressing block 210 on both sides of the clamping mechanism 100, that is, one moving block 220 in embodiment 1 is an active part, and the other is passively moved by the clamping block 101, while the two moving blocks 220 in embodiment 2 are both active parts, so the clamping force distribution is more uniform.

[0076] Example 3

[0077] like Figure 8 As shown, the difference between this embodiment and embodiment 1-2 is that the inclined surface 201 of the pressing block 210 is a rounded structure, and the inclined surface 201 of the moving block 220 is a concave arc shape. When the pressing block 210 is pressed down, due to the structural characteristics of the concave arc shape, the moving block 220 can be moved quickly initially, and then the clamping block 101 can quickly approach the sheet-like cleaning sheet.

[0078] Example 3

[0079] like Fig. 9As shown, the difference between this embodiment and embodiments 1-3 is that the inclined surface 201 of the pressing block 210 is a rounded structure, and the inclined surface 201 of the moving block 220 is a convex arc shape. When the pressing block 210 is pressed down, due to the structural characteristics of the convex arc shape, it is more labor-saving when the clamping block 101 quickly clamps the sheet-like cleaning sheet, and it is suitable for sheet-like cleaning sheets with harder materials.
