When the positioning piece is in the first state, the mop rod joint is vertical to the mop plate; when the positioning piece is in the second state, the mop rod joint can rotate relative to the middle connecting part.

After the two side plates rotate downwards relative to each other by a preset angle, the middle of the wiping part extrudes the positioning piece, so that the positioning piece moves from the second state to the first state.

A return spring 430 is also included that allows the positioning member to be positioned in the second state when not subject to an external force. Or after the extrusion force of the wiping part on the positioning piece is cancelled, the return spring enables the positioning piece to return to the second state from the first state.

Specifically, a sliding hole 412 is formed in the intermediate connecting portion, the positioning member is slidably mounted in the sliding hole, and the return spring 430 is disposed between the positioning member and the intermediate connecting portion.

In addition, in order to prevent the positioning member from separating from the intermediate connecting portion, the positioning member is provided with a sliding buckle 432, a sliding bayonet 414 is arranged at a corresponding position on the intermediate connecting portion, and the sliding buckle is limited in the sliding bayonet, so that the positioning member can slide between the first state and the second state and cannot separate from the intermediate connecting portion.

Two connecting lugs 411 rotatably connected with the mop rod joint are symmetrically arranged at the upper end of the middle connecting part, and the sliding hole 412 is positioned between the two connecting lugs. That is to say, location bayonet socket is located two connections and position between, and two engaging lugs connect with the mop pole and rotate to be connected and make the mop pole connect and have stable rotation connection state, can ensure after location dop card goes into the location bayonet socket that the mop pole connects and middle connecting portion keeps firm vertical state.

In addition, when the wiping part drives the positioning piece to enter the first state from the second state, the vertical positioning part and the vertical positioning surface play a role in auxiliary positioning, so that the positioning clamping head is aligned with the positioning bayonet to be beneficial to the clamping of the positioning clamping head into the positioning bayonet.

Furthermore, be connected with the elastic component between intermediate junction portion and the two curb plates respectively, the elastic component is torsional spring 45, and according to the adjustment of elastic component connected mode, the elastic component also can be pressure spring or extension spring, the elastic component makes two curb plates can be positioned the coplanar state. The elastic force of the elastic piece can be adjusted according to actual needs, so that when the wiping part is basically squeezed and faces downwards, the two side plates can be unfolded to be in the same plane state and kept stable.

In addition, an outer raised head 420 is arranged at the outer end position of the upper end of the side plate; the outer end face of the side plate is provided with more than one anti-slip strip 421. The function of the outer nib and cleats is related to the wringing of the mop, as explained below when the wringing function is described.

The lower end of the side plate is connected with a quick-release connecting plate 46, and the quick-release connecting plate is connected with the wiping part through a detachable buckle.

The mop is characterized in that an extruder 2 is arranged in the barrel body 1, one side of the extruder arranged in the barrel body is defined as a water squeezing area, one side of the barrel body, which is different from the extruder, is defined as a cleaning area, water is contained in the barrel body, and the mop plate can move up and down in the water in the cleaning area to realize cleaning. The squeezer comprises a squeezing frame 21 and two squeezing parts 22 movably connected with the squeezing frame; each extrusion part is connected with the extrusion frame through two rotating connecting plates 23, and two ends of each rotating connecting plate are respectively connected with the extrusion frame and the extrusion part in a rotating mode.

Specifically, as shown in fig. 7, two sides of each end of the rotating connection plate are respectively provided with a rotating head, the extrusion frame is provided with a rotating hole 213 rotatably connected with the rotating head, and the extrusion portion is provided with a rotating connection hole rotatably connected with the rotating head.

An extrusion opening is formed between the two extrusion parts, and as shown in fig. 3, when the extrusion parts are in an initial state, a horn mouth shape with a narrow top and a wide bottom is formed between the rotary connecting plates at two sides; as shown in fig. 5 and 6, when the two squeezing portions are displaced downward relative to the barrel body, the width of the squeezing opening is reduced.

A side plate positioning step 221 is formed on one side of the extrusion part facing the extrusion opening; the outer end of the side plate can be temporarily positioned on the side plate positioning step, so that the squeezing part can be displaced along with the downward movement of the mop plate. The anti-slip strips on the side plates are abutted to the side plate positioning steps, so that friction force is increased, and the end parts of the side plates can be prevented from being accidentally separated from the side plate positioning steps.

When the mop drives the squeezing part to move downwards relative to the barrel body, the squeezing part drives the two side plates to move in opposite directions, and then the wiping part is squeezed.

The outer end position of the upper end of the side plate is provided with the outer raised head 420, and the upper part of the side plate positioning step on the extruding part is provided with a blocking wall 222 which is matched with the outer raised head to block the end part of the side plate from being separated from the side plate positioning step.

Two pre-extrusion guide parts 211 are symmetrically arranged on one side, close to the cleaning area, of the extrusion frame, the pre-extrusion guide parts are integrally in a downward convex arc shape, before the mop moves from top to bottom to achieve water extrusion, the outer end parts of the side plates or the upper end surfaces close to the outer end parts can slide upwards to the extrusion parts along the pre-extrusion guide parts, and finally the outer end parts of the side plates slide to the positions above the side plate positioning steps.

When the two side plates are forced to rotate downwards and oppositely by the squeezer, the contact position of the side plates and the pre-squeezing guide part is more labor-saving as the distance from the middle position of the mop plate is farther, so that the optimal condition is that the mop plate is always in contact with the pre-squeezing guide part through the outer end position of the side plates in the process of moving upwards relative to the squeezer.

That is, when the shape of the pre-pressing guide portion or the shape of the side plate is designed such that the side plate slides upward relative to the pre-pressing guide portion, the outer end of the side plate or a portion of the side plate near the outer end is in sliding contact with the pre-pressing guide portion. Except for designing the pre-extrusion guide part into an arc mode, the outer raised head is properly enlarged, so that the outer raised head is always contacted with the pre-extrusion guide part in the upward movement process of the side plate, and the same aim can be achieved.

In other embodiments, before the mop moves from top to bottom to realize water squeezing, the two side plates of the mop can also slide upwards along the rotating connecting plate, so that the two side plates rotate towards each other by a preset angle, and the outer end parts of the side plates slide above the side plate positioning steps.

Furthermore, the squeezer also comprises an elastic element, and the elastic element enables the squeezing part to be positioned at the initial position when the squeezing part is not acted by external force, or the squeezing part returns to the initial position after the external force applied to the squeezing part is cancelled. In this embodiment, the elastic element is a return tension spring 24 connected between the extrusion frame and the rotating connection plate. In other embodiments, the elastic element may be a tension spring connected between the two rotation connection plates, a tension spring connected between the pressing portion and the pressing frame, or a torsion spring b connected between the rotation connection plate and the pressing portion or the pressing frame.

The elastic element is not only used for driving the squeezing part and the rotating connecting plate to reset, but also can ensure that the side plate of the mop plate can be smoothly separated from the squeezing part after the wiping object is squeezed.

Specifically, the process of the mop plate in the wringing state is slower than the resetting process of the squeezing part due to the influence of factors such as the self weight of the wiping part, the friction force between the side plate and the middle connecting part and the like, so that the mop plate can quickly pull up after wringing, the outer convex head at the outer end of the side plate can smoothly cross the blocking wall, and the mop can be separated from the squeezer.

It should be noted that, when the wiping part is not squeezed, the squeezing part is moved back and forth between the upper limit position and the lower limit position by pushing and pulling the mop rod up and down to squeeze the wiping part, and the mop needs to be pulled up slowly, so that the blocking wall can effectively block the side plate from moving up to the position away from the squeezing part, and the repeated water squeezing operation is facilitated.

Further, a limiting plate 215 is arranged on one side of the extrusion frame, which is far away from the cleaning area, and a limiting chute 214 is arranged on the limiting plate; and a limiting sliding part 223 is arranged on one side, close to the limiting plate, of the extrusion part, and the limiting sliding part is in sliding connection with the limiting sliding groove.

The limiting sliding groove is matched with the limiting sliding part, so that the extrusion part is kept in a state of being approximately parallel to the limiting plate in the up-and-down moving process, and the phenomenon that the rotating connecting plate is excessively bent to be damaged or separated from the extrusion frame due to the fact that the extrusion part is compressed by the wiping part in the downward moving process is avoided.

Further, the squeezer 2 is detachably connected into the barrel body 1, and a limiting and supporting part 11 is arranged at the bottom in the barrel body; when the extrusion part moves downwards to abut against the limiting support part, the extrusion part reaches the limit position of downward movement.

When the squeezing part moves downwards to the limit position, the two side plates of the mop plate rotate oppositely to be in a state of being approximately parallel, the wiping part is close to the maximum squeezing amplitude, and the squeezing of water in the wiping part is facilitated. The limiting support part enables the squeezing part not to move over the head to cause damage or even breakage of the rotating connecting plate, and meanwhile, the side plate of the mop plate is also ensured not to enable the squeezing part to move over the head to be separated from the side plate positioning step.

Further, a clamping ring 212 is arranged at the upper end of the extrusion frame, and the clamping ring is matched with the inner peripheral shape of the opening at the upper end of the barrel body; the rand passes through the buckle and the upper end opening inner wall joint of staving.

The rand suits with staving upper end opening shape, makes like this that extrusion frame and staving can keep firm after being connected, and the rand joint is in staving upper end opening inner periphery simultaneously, also makes thin wall structure's staving difficult production warp.

In addition, the extrusion frame is also provided with a top plate 210, and the top plate is connected with the limiting plate and the pre-extrusion guide part. The upper end of the limiting plate is further provided with a flow guide surface 216 corresponding to the extrusion port, and the flow guide surface is used for guiding part of water extruded by the side surface of the wiping part, so that the water extruded by the wiping part is prevented from splashing outside the barrel body.

In addition, the barrel body is rotatably connected with a lifting handle 10 through a rotating pin 12, and the lifting handle 10 which is integrally U-shaped can be accommodated at the upper end position of the cleaning area in the barrel body.

When the mop is cleaned, as shown in figure 2, the mop plate extends out of water in a cleaning area of the barrel body and moves up and down, so that dirt adhered on the cleaning part is separated from the cleaning part, after the cleaning part is cleaned, as shown in figure 3, the mop plate is moved to the position below the squeezer along the width direction of the barrel body through the mop rod, then the mop rod is pulled upwards as shown in figure 4, so that two side plates of the mop plate slide upwards along the pre-squeezing guide part until an outer convex head at the end part of the side plate crosses the side plate positioning step and stops pulling the mop rod, as shown in figure 5, at the moment, because the cleaning part is in a bending state, the upper end position in the middle of the cleaning part squeezes the positioning part, so that the positioning part is pushed to move upwards, the positioning convex head is clamped into the positioning bayonet at the lower end of the mop rod joint, so that the mop rod and the middle connecting part are stably fixed in a vertical state, and then the mop rod is pushed downwards, make the curb plate drive extrusion portion downstream, meanwhile, extrusion portion drives two curb plates and rotates in opposite directions, thereby make the dehydration of wiping portion realized the wiping portion by the extrusion, promote extrusion portion to the extreme position back shown in figure 6 downwards, can be as required, continue slowly repeating pull-up, push down mop pole a plurality of times, make the wiping portion extruded more futilely, also can reach the extreme position back shown in figure 6 at the extrusion portion, make the wiping portion be in and receive extrusion state for a short period of time, make the water of wiping portion drip to the staving in by oneself.
