Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and particularly relates to a mop head assembly. Background Art

[0002] In the prior art, there is a Chinese utility model patent with the patent number 《202121937649.8》 and the patent name: A cloth clamping mop. It drives the clamping assembly to work by pushing and pulling the mop rod and through the cooperation of a gear and a rack, so as to clamp or disassemble the mop cloth. However, since the working environment of the mop will contact some dirty water or dust, the gear and the rack will be stuck, thus affecting the normal operation of the clamping assembly. Moreover, setting the gear and the rack on the mop head makes its internal structure relatively complex and the production cost relatively high. Summary of the Invention

[0003] Objective of the utility model: In order to overcome the defects of the prior art, the utility model provides a mop head assembly which drives the first clamping plate and the second clamping plate to open or close by means of connecting rod pushing and pulling, can prevent dust or stones from getting stuck, and has a simple and relatively stable structure.

[0004] The utility model discloses a mop head assembly, which includes a mop head. A first clamping plate and a second clamping plate are slidably guided on the mop head, and a driving assembly for driving the first clamping plate and the second clamping plate to open or close is further arranged on the mop head. It is characterized in that: the driving assembly includes a driving part that can push, pull, lift relative to the mop head and a connecting rod arranged on the driving part. The connecting rod includes a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod are arranged in a staggered manner and are hinged on the driving part. One end of the first connecting rod far away from the driving part is hinged on the first clamping plate, and one end of the second connecting rod far away from the driving part is hinged on the second clamping plate.

[0005] Adopting the above technical solution, during use, by pushing or pulling the driving part, the angles of the first connecting rod and the second connecting rod can be changed, thereby pushing or pulling the first clamping plate and the second clamping plate to make the two open or close relatively. It drives the clamping assembly to open or close by means of connecting rod pushing and pulling, can prevent dust or stones from getting stuck, and has a simple and relatively stable structure.

[0006] A further setting of the utility model: It further includes a first positioning structure for positioning after the first clamping plate and the second clamping plate open or close.

[0007] Adopting the above technical solution, it can prevent the first clamping plate and the second clamping plate from automatically opening or closing, and is more stable when in use.

[0008] Further setting of the present utility model: A first hinge head is hingedly arranged on the driving member, and a second hinge head is hingedly arranged on the first hinge head. The hinge directions of the first hinge head and the second hinge head are perpendicular. A second positioning structure is provided between the first hinge head and the driving member, and a third positioning structure is provided between the second hinge head and the first hinge head. One end of the second hinge head facing outward is a connecting end.

[0009] With the above technical solution, the mop head can rotate relatively when configuring the mop rod through the hinge connection of two hinge heads, which has stronger practicability. The connecting end is convenient for connecting the mop rod. The second positioning structure and the third positioning structure can prevent the mop head from rotating easily, making it more stable during use.

[0010] Further setting of the present utility model: The first positioning structure includes a positioning surface provided on the mop head and a positioning block provided on the driving member. When the driving member moves up and down relative to the mop head, the positioning surface can cooperate with the positioning block to achieve positioning.

[0011] With the above technical solution, when the driving member slides by itself, the positioning block can abut against the positioning surface, thereby restricting its sliding, and thus achieving a positioning effect.

[0012] Further setting of the present utility model: A deformable elastic sheet is provided on the mop head, the positioning surface is provided on the elastic sheet, the positioning surface is a ramp surface, and the positioning block is provided with an inclined surface adapted to the ramp surface.

[0013] With the above technical solution, the automatic sliding can be restricted through the cooperation of the ramp surface and the inclined surface, thereby achieving a positioning effect. Further, the elastic sheet can be deformed by an external force to form an avoidance, which will not affect the normal adjustment of the driving member, and the structural layout is relatively reasonable.

[0014] Further setting of the present utility model: The driving member is guided and slid on the mop head, and a cover body for restricting the sliding displacement of the driving member is further provided on the mop head. The cover body is detachably connected to the mop head and is provided with a limiting surface for restricting the backward displacement of the driving member.

[0015] With the above technical solution, the sliding displacement of the driving member can be restricted, thereby preventing the first connecting rod and the second connecting rod from detaching, making it more stable during use. Description of the Drawings

[0025] The following further details the specific implementation manners of the present utility model with reference to the accompanying drawings:

[0026] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0027] The present utility model discloses a mop head assembly, which includes a mop head 1. On the mop head 1, a first clamping plate 2 and a second clamping plate 3 are guided and slidably arranged (the most preferred way to realize the guided sliding of the first clamping plate 2 and the second clamping plate 3 is by the cooperation of a slider and a slide rail, and the slide rail is most preferably also provided with a limit hook to prevent the slider from disengaging from the slide rail. The limit hook is most preferably arranged on a deformable elastic sheet. The first clamping plate 2 and the second clamping plate 3 are most preferably also provided with anti-slip teeth to prevent the rag from falling off when clamping the rag). And on the mop head 1, there is also a driving assembly 4 for driving the first clamping plate 2 and the second clamping plate 3 to open or close. In the embodiment of the present utility model, the driving assembly 4 includes a driving member 41 that can be pushed, pulled, and lifted relative to the mop head 1 and a connecting rod 42 arranged on the driving member 41 (the driving member 41 is most preferably a push block or a push rod). The connecting rod 42 includes a first connecting rod 421 and a second connecting rod 422. The first connecting rod 421 and the second connecting rod 422 are arranged in a staggered manner and are hinged on the driving member 41. One end of the first connecting rod 421 away from the driving member 41 is hinged on the first clamping plate 2, and one end of the second connecting rod 422 away from the driving member 41 is hinged on the second clamping plate 3).

[0028] Adopting the above technical solution, during use, by pushing or pulling the driving member 41, the angles of the first connecting rod 421 and the second connecting rod 422 can be driven to change, thereby pushing or pulling the first clamping plate 2 and the second clamping plate 3, so that the two open or close relative to each other. The way of using the connecting rod to push and pull to drive the first clamping plate 2 and the second clamping plate 3 to open or close can prevent dust or stones from getting stuck, and the structure is simple and relatively stable.

[0029] It further includes a first positioning structure 5 for positioning after the first clamping plate 2 and the second clamping plate 3 open or close, which can prevent the first clamping plate 2 and the second clamping plate 3 from automatically opening or closing, and is more stable when in use.

[0030] A first hinge joint 61 is hinged on the driving member 41. A second hinge joint 62 is hinged on the first hinge joint 61. The hinge directions of the first hinge joint 61 and the second hinge joint 62 are perpendicular. And between the first hinge joint 61 and the driving member 41, there is a second positioning structure 63. Between the second hinge joint 62 and the first hinge joint 61, there is a third positioning structure 64. And the outer end of the second hinge joint 62 is a connecting end 621. By hinging with two hinge joints, the mop head 1 can rotate relative to each other when configuring the mop rod, which has stronger practicability. The connecting end 621 can facilitate the connection of the mop rod. The second positioning structure 63 and the third positioning structure 64 can prevent the mop head 1 from rotating easily and make it more stable when in use. The second positioning structure 63 and the third positioning structure 64 are most preferably realized by the cooperation of a positioning groove and a positioning block. Of course, it can also be realized by the way of a top pin and a positioning hole or by a tight fit method for positioning.

[0031] The first positioning structure 5 includes a positioning surface 51 provided on the mop head 1 and a positioning block 52 provided on the driving member 41. When the driving member 41 moves up and down relative to the mop head 1, the positioning surface 51 can cooperate with the positioning block 52 to achieve positioning. When the driving member 41 slides by itself, the positioning block 52 can abut against the positioning surface 51, thereby restricting its sliding, so as to achieve a positioning effect. Of course, the first positioning structure 5 can also be positioned by means of tight fitting or by means of springs and ejector pins.

[0032] A deformable elastic sheet 7 is provided on the mop head 1, the positioning surface 51 is provided on the elastic sheet 7, the positioning surface 51 is a ramp surface, and the positioning block 52 is provided with an inclined surface adapted to the ramp surface. By the cooperation of the ramp surface and the inclined surface, its automatic sliding can be restricted, so as to achieve a positioning effect. Further, the elastic sheet 7 can be deformed by an external force, so as to form an avoidance, and it will not affect the normal adjustment of the driving member 41. The structural layout is relatively reasonable.

[0033] The driving member 41 is guided and slides on the mop head 1, and a cover body 8 for restricting the sliding displacement of the driving member 41 is further provided on the mop head 1. The cover body 8 is detachably connected to the mop head 1 and is provided with a limiting surface for restricting the backward displacement of the driving member 41, so that the sliding displacement of the driving member 41 can be limited, thereby preventing the first connecting rod 421 and the second connecting rod 422 from disengaging (adopting this structure enables the first connecting rod 421 and the second connecting rod to be connected to the corresponding clamping plates by means of buckles), making it more stable during use.
