The present disclosure relates to the technical field of cleaning tools, and in particular, to a cloth clamping mop with easy-to-replace mop cloth.
Mops are often configured to clean the floor. Mop cloth is mounted on a mop head, and a mop handle is held to clean the floor. Most mops on the market employ fixed mop cloth, which is more troublesome to replace. The mops are often used for a long time and thus will become places for dirt and grime to accumulate. If the mops are discarded directly, it will cause unreasonable resource utilization, resulting in waste.
In the prior art, for example, CN205729270U provides a novel mop cloth clamping structure and a mop, including a mop plate and mop cloth; the mop plate includes an aluminum profile support plate, a bottom plate clamped with a bottom surface of the aluminum profile support plate, two cloth clamping plates pivotally connected to both sides of the aluminum profile support plate respectively, and two seal heads disposed at front and rear ends of the aluminum profile support plate respectively; chutes and ribs are disposed on both sides of the aluminum profile support plate; the cloth clamping plates are provided with at least two rotating shaft-shaped clamping components clamped with the chutes, and at least two clamping teeth matched with the ribs correspondingly to clamp and fix the mop cloth. Although the above structure achieves the purpose of replacing the mop cloth, it requires a user to manually rotate the cloth clamping plates, which is inconvenient in mop cloth replacement.
The technical problem to be solved by the present disclosure is to provide a cloth clamping mop with easy-to-replace mop cloth, which is provided with driving assemblies configured to connect second clamping members to a mop rod, so that the second clamping members can be controlled to move close to or away from first clamping members by lifting or pressing the mop rod; and therefore, the mop cloth is clamped or released after the second clamping members move close to or away from the first clamping members. The cloth clamping mop is simple in structure and more convenient in operation of mop cloth replacement.
The solution adopted by the present disclosure to solve the above technical problem is to provide a cloth clamping mop with easy-to-replace mop cloth. The cloth clamping mop includes a mop rod, and a mop bottom plate connected to one end of the mop rod; the mop bottom plate is provided with a clamping assembly configured to clamp the mop cloth; the clamping assembly includes first clamping members at the end of the mop bottom plate far away from the mop rod, and second clamping members movably connected to the mop bottom plate and capable of moving close to or away from the first clamping members; the mop bottom plate is further provided with driving assemblies configured to drive the second clamping members to move close to or away from the first clamping members; and the mop rod is connected to the driving assemblies, and the driving assemblies are controlled to drive the second clamping members to move close to or away from the first clamping members by lifting or pressing the mop rod.
Specifically, the mop cloth is made of thin non-woven fabric.
Optionally, the mop rod is lifted up to control the second clamping members to move away from the first clamping members, the mop bottom plate is placed on the mop cloth, and the mop rod is pressed down to control the second clamping members to move close to the first clamping members, the mop cloth is clamped between the first clamping members and the second clamping members, thus achieving the cloth clamping function; when the mop cloth is released, the mop rod is lifted up to move the second clamping members away from the first clamping members, and thus the mop cloth is enabled to fall off; and in the clamping process, part of the mop cloth is squeezed between the first clamping members and the second clamping members, so that the purpose of clamping the cloth is achieved.
Alternatively, the mop rod is pressed down to control the second clamping members to move away from the first clamping members, and the mop rod is lifted up to control the second clamping members to move close to the first clamping members.
By adopting the above solution, the driving assemblies are provided to be configured to connect the second clamping members to the mop rod, so that the second clamping members can be controlled to move close to or away from the first clamping members by lifting or pressing the mop rod; and therefore, the mop cloth is clamped or released after the second clamping members move close to or away from the first clamping members. The cloth clamping mop is simple in structure and more convenient in operation of mop cloth replacement.
Further, each of the driving assemblies includes a driving gear; and each of the second clamping members includes rack portions meshing with the driving gears for transmission.
Further, the second clamping members are respectively disposed at two opposite ends of the first clamping members located on the same plane as the first clamping members;
Preferably, the second clamping members are connected below the clamping driving members in a snap connection manner.
Specifically, the two clamping driving members are disposed on two opposite sides of the driving gears, making the two clamping driving members be driven to move synchronously by the rotation of the driving gears, so that the two second clamping members are driven to move close to or away from the first clamping members synchronously; and therefore, the mop cloth is more convenient to replace.
Further, each of the rack portions is provided with a first restricting portion and a second restricting portion at both ends of a tooth portion of each of the rack portions configured to restrict the corresponding driving gear; when where the driving gears rotate until the driving gears are abutted against the first restricting portions, the second clamping members are farthest away from the first clamping members, and the first clamping members and the second clamping members are in a maximum open state, making the mop cloth fall off more easily; and when the driving gears rotate until the driving gears are abutted against the second restricting portions, the second clamping members are closest to the first clamping members, and the first clamping members and the second clamping members are in a state of mutual clamping and locking, making the cloth clamping function more reliable.
Preferably, the rack portions are provided above the clamping driving members, and the rack portion of any clamping driving member is partially placed above the other clamping driving member; the extending directions of the tooth portions of the rack portions are parallel to the movement directions of the clamping driving members and the second clamping members; and meanwhile, when the driving gears rotate until the driving gears are abutted against the second restricting portions, end faces of the two clamping driving members close to each other are just abutted against each other, which further restricts the mutual movement of the two clamping driving members, making the cloth clamping function more reliable.
By adopting the above solution, due to arrangement of the first restricting portions and the second restricting portions, the first clamping members can be prevented from detaching from the mop bottom plate, making it more reliable to use.
Further, the mop bottom plate includes a mop cover plate connected to the mop rod, and the first clamping members detachably connected on the side of the mop bottom plate far away from the mop rod; extension outlets are reserved in side faces of the mop cover plate for the clamping driving members to extend out of the extension outlets; and opening portions are reserved at the end of the mop cover plate far away from the first clamping members for the driving gears to partially extend out of the opening portions to be connected to the mop rod.
Preferably, a plurality of snap fasteners are formed by extending downwards from a bottom of the mop cover plate, and correspondingly, the first clamping members include snap holes matched with the snap fasteners, so as to achieve a detachable connection between each of the snap fasteners and the corresponding snap hole and facilitate subsequent maintenance.
In another optional solution, each of the driving assemblies includes a cam rotating circumferentially about the central axis of the mop rod, and a reset member configured to reset the corresponding second clamping member. In this structure, when the most protruding parts of the cams abut against the second clamping members, the second clamping members and the first clamping members are in an open state. When the cams rotate to make the most protruding part slowly detach from the second clamping members, the reset members drive the second clamping members to move close to the first clamping members until the first clamping members and the second clamping members are clamped and locked.
Further, first toothed areas are disposed at the ends of the first clamping members facing the second clamping members, second toothed areas are disposed at the ends of the second clamping members facing the first clamping members, and the first toothed areas and the second toothed areas are formed in a staggered manner, which can improve the reliability of cloth clamping.
Further, the mop rod includes an outer rod connected to the mop bottom plate, and an inner rod slidably connected inside the outer rod; the inner rod is internally provided with a screw rod, and at least a part of an inner wall of the inner rod is matched with the screw rod; and the screw rod is connected to the driving assemblies by ways of connecting members.
Specifically, the screw rod is rotatably connected to the parts of the driving gears extending out of the mop bottom plate by ways of the connecting members; external connecting members are connected to the bottom of the outer rod, the external connecting members are sleeved outside the connecting members, and the external connecting members are rotatably connected to the mop bottom plate; rotating bases rotatably connected to the external connecting members are disposed on a top end of the mop bottom plate; and moreover, since the rotation directions of the connecting members and the driving gears are the same as those of the external connecting members and the mop bottom plate, the whole mop rod can rotate relative to the mop bottom plate, making it possible to adjust an angle between the mop rod and the mop bottom plate.
Further, a plurality of elastic buckles arranged at equal intervals in an annular shape are formed by extending downwards from a lower end of the inner rod, and an outer wall of the screw rod protrudes to form a protruding portion matched with the elastic buckles.
When in use, the inner rod is lifted up, and the protruding portion of the screw rod is detached from the elastic buckles; since an inner wall of the inner rod is matched with the screw rod, the screw rod can be driven to rotate, and the driving gears are thus driven to rotate by ways of the connecting members, driving the second clamping members to move away from the first clamping members so as to enable the second clamping members and the first clamping members to loose; when clamping, the inner rod is pressed down; since the inner wall of the inner rod is matched with the screw rod, the screw rod can be driven to rotate relatively in the opposite direction, and the driving gears are thus driven to rotate relatively in the opposite direction by ways of the connecting members, driving the second clamping members to move close the first clamping members so as to enable the second clamping members and the first clamping members to clamp the mop cloth tightly; and meanwhile, the protruding portion of the screw rod is locked on the elastic buckles, making the screw rod be locked with the inner rod, thereby improving the reliability during the subsequent mopping process.
Further, at least a part of an inner wall of the outer rod is provided with axially arranged guide sliding platforms, and correspondingly, the inner rod is provided with guide chutes matched with the guide sliding platforms, so as to prevent the inner rod and the outer rod from being offset.
Further, the second clamping members are respectively disposed at the two opposite ends of the first clamping members located on the same plane as the first clamping members, and the driving assemblies are capable of driving the two second clamping members to move close to or away from each other along the plane where the first clamping members are located, so that the mop cloth is more convenient to replace.
Further, each of the driving assemblies includes linkage mechanisms connected between the second clamping members and the end of the mop bottom plate close to the mop rod, elastic members acting between the two second clamping members and capable of giving the two second clamping members a tendency to move in a direction away from each other, and pressing members connected at the end of the mop rod close to the mop bottom plate and capable of acting on the linkage mechanisms to drive the two second clamping members to move in a direction close to each other.
Preferably, the first toothed areas are disposed at the ends of the first clamping members facing the second clamping members, the second toothed areas are disposed at the ends of the second clamping members facing the first clamping members, and the first toothed areas and the second toothed areas are formed in a staggered manner, which can improve the reliability of cloth clamping.
Specifically, the mop rod includes the outer rod connected to the mop bottom plate, and the inner rod slidably connected inside the outer rod, where the outer rod is fixed to the mop bottom plate; the pressing members are connected to a bottom end of the inner rod, and thus the pressing members can be synchronously moved up or down by lifting or pressing the inner rod; after the inner rod is lifted up to drive the pressing members to move upwards, the pressing members are detached from the linkage mechanisms, so that the two second clamping members are pushed to move in a direction away from each other due to resilience of the elastic members, making the second clamping members move away from the first clamping members so as to release the mop cloth for easy replacement; and after the inner rod is pressed down to drive the pressing members to move downwards, the pressing members will exert a force on the linkage mechanisms, making the linkage mechanisms drive the two second clamping members to move in a direction close to each other, so that the second clamping members are enabled to move close to the first clamping members until the first clamping members and the second clamping members are in a mutually clamped and locked state, making the cloth clamping function more reliable.
Further, each of the linkage mechanisms includes first connecting rods hinged to the two second clamping members respectively, and second connecting rods hinged to the other ends of the two first connecting rods respectively, and the other ends of the two second connecting rods are hinged to the end of the mop bottom plate close to the mop rod; after the mop rod is lifted up, the pressing members are detached from the linkage mechanisms, and the two second clamping members are driven to move in a direction away from each other due to resilience of the elastic members; and meanwhile, the hinged joints between the first connecting rods and the second connecting rods are unfolded with relative upward and outward motions until the first connecting rods and the second connecting rods are in the same straight line; and at this time, the second clamping members are enabled to be farthest away from the first clamping members; after the mop rod is pressed down, the pressing members act on the linkage mechanisms to drive the hinged joints between the first connecting rods and the second connecting rods to make relative downward and inward motions, driving the two second clamping members to move in a direction close to each other; and at this time, the second clamping members are enabled to be closest to the first clamping members, and meanwhile the first connecting rods and the second connecting rods are in a nearly vertical state.
Preferably, there are two sets of linkage mechanisms symmetrically disposed relative to the mop rod; there are two elastic members symmetrically disposed relative to the mop rod; each of the second clamping members includes a long strip-shaped clamping rod provided with the second toothed areas, and extension rods extending from the clamping rod towards the other second clamping member; each clamping rod is provided with the two extension rods respectively located on both sides of the mop rod; abutting portions configured to abut against the elastic members are disposed at the connecting joints between the extension rods and the clamping rods; accommodating grooves configured to accommodate the elastic members and connected to the abutting portions are also formed in the extension rods, and thus the elastic members are placed in the accommodating grooves of the two extension rods with their both ends being respectively abutted against the two abutting portions; and moreover, when the first clamping members and the second clamping members are in a mutually clamped and locked state, the elastic members are in a compressed energy storage state; and then after the pressing members are detached from the linkage mechanisms, the resilience generated by the compressed energy of the elastic members will drive the two second clamping members to move in a direction away from each other, making the second clamping members move away from the first clamping members so as to release the mop cloth for easy replacement.
Further, the mop bottom plate is provided with a moving groove along the moving direction of the mop rod for the pressing members to move; each of the moving grooves is provided with a first limiting portion and a second limiting portion respectively formed at both ends of the movement direction of the mop rod; the first limiting portions are formed at the side close to the mop rod, and the second limiting portions are formed at the side close to the mop bottom plate; when the mop rod is lifted up until the pressing members are abutted against the first limiting portions, the second clamping members are farthest away from the first clamping members; and when the mop rod is moved down until the pressing members are abutted against the second limiting portions, the second clamping members are closest to the first clamping members.
Preferably, a locking structure is further provided between the outer wall of the inner rod and the inner wall of the outer rod; when the inner rod is moved down until the pressing members are abutted against the second limiting portions, the locking structure locks the inner rod and the outer rod together to limit the sliding movement of the inner rod relative to the outer rod; and at this time, the second clamping members are closest to the first clamping members, that is, the first clamping members and the second clamping members are in a mutually clamped and locked state.
Specifically, the moving groove is communicated with the inner cavity of the mop bottom plate, and the pressing members include pressing portions that can extend into the moving groove and abut against the linkage mechanisms; the pressing members further include sliding portions located directly below the inner rod, the mop bottom plate is provided with sliding grooves for the sliding portions to slide, and the sliding portions are always placed in the sliding grooves so as to make the movement of the pressing members more stable; the two pressing portions are disposed on each of the sliding portions at both ends of the inner rod, exerting a force on the corresponding linkage mechanism; and meanwhile, during the unfolding and contraction processes of the linkage mechanisms, the pressing portions move along outer side walls of the second connecting rods.
