DETAILED DESCRIPTION

[0031] According to Figures 1 to 7 , the embodiment is a mop with cloth clamping function, which comprises a mop rod 1 and a mop plate 3 movably connected to the lower end of the mop rod, and two movable clamping pieces are movably connected to the two sides of the mop plate respectively, and a clamping opening for clamping the mop is formed between the movable clamping pieces and the mop plate.

[0032] According to Figure 5 and Figure 6 , each movable clamping piece is provided with two or more sliding arms 41, which are slidably connected to the mop plate along the width direction of the mop plate, and each sliding arm is provided with a transmission inclined sliding groove 42 at an angle to the length direction of the movable clamping piece, and the angle between the transmission inclined sliding groove and the length direction of the movable clamping piece is 30-60 degrees, and in the embodiment, the angle is 45 degrees. The end of the transmission inclined sliding groove close to the movable clamping piece is provided with a positioning groove 421. A driving sliding block 7 is slidably installed in the mop plate along the length direction of the movable clamping piece, the driving sliding block is provided with a sliding protrusion 71 in transmission connection with the transmission inclined sliding groove, and a control component is provided on the upper side of the mop plate or the mop rod in linkage with the driving sliding block.

[0033] When the sliding protrusion slides relative to the transmission inclined sliding groove, the clamping opening is opened or closed, and when the sliding protrusion is located in the positioning groove, the clamping opening is kept in the closed state. As Figure 6 shown, the positioning groove is parallel to the length direction of the movable clamping piece, or the positioning groove can also be at an angle less than 30 degrees to the length direction of the movable clamping piece, as long as the sliding protrusion does not come out of the positioning groove when the driving sliding block is not affected by external force after the sliding protrusion slides into the positioning groove.

[0034] In some other embodiments, the positions of the transmission inclined sliding groove and the sliding protrusion are adjusted.

[0035] In order to make the mop rod flexible rotation relative to the mop plate, the middle part of the mop plate upper end is rotationally connected with a hinge 6, the hinge is rotationally connected with a connecting sleeve 2, the connecting sleeve is slidably connected with a transmission joint 11, the upper end of the transmission joint is connected with the mop rod 1, the transmission joint is connected with the driving slider through a bidirectional driving rope 5, and the bidirectional driving rope passes through the hinge. The bidirectional driving rope is a rod-shaped or tubular component capable of transmitting both pulling force and pushing force.

[0036] In the embodiment, the bidirectional driving rope is a nylon rod with a diameter of 2-4 mm, preferably a nylon rod with a diameter of 3 mm, the two ends of the nylon rod are integrally formed with connecting parts 51, the lower part of the transmission joint is provided with a driving rope interface 13 for fixing the connecting part of one end of the nylon rod, and the upper part of the driving slider is provided with a driving rope connecting port 73 for fixing the connecting part of the other end of the nylon rod. In other embodiments, the bidirectional driving rope can also be a metal tension spring or a brake line tube, as long as it can be bent and can transmit both pushing force and pulling force.

[0037] When the transmission joint moves relative to the lower end of the connecting sleeve, the bidirectional driving rope drives the driving slider to move to close the clamping opening; the bidirectional driving rope, the transmission joint and the mop rod constitute the operating component.

[0038] In combination with FIGS. 1-4, Figure 3 , Figure 4 As shown, the transmission joint is provided with an elastic positioning buckle 12, which can be a V-shaped metal elastic buckle or an elastic buckle integrally formed on the transmission joint, and the connecting sleeve is provided with an upper positioning hole 21 and a lower positioning hole 22 capable of being clamped relative to the positioning buckle; when the sliding convex head is located in the positioning groove, the positioning buckle is clamped relative to the lower positioning hole; when the sliding convex head is located at the end of the transmission inclined sliding groove away from the positioning groove, the positioning buckle is clamped relative to the upper positioning hole.

[0039] In order to make the clamping opening stably maintain in the closed or open state, the transmission joint is provided with an elastic positioning buckle matched with the upper positioning hole and the lower positioning hole, so as to respectively make the clamping opening stably maintain in the open state and the closed state. When the mop is installed, the positioning buckle is clamped relative to the upper positioning hole, and the resistance between the positioning buckle and the upper positioning hole makes the initial speed of the mop rod be relatively high when it is pressed down, and makes the mop plate and the movable clamping part have a relatively large pre-tightening force on the mop, that is, the clamping opening can be quickly changed from the open state to the closed state, which is beneficial to the movable clamping part driving the mop to move to the mop plate direction through the friction force, and significantly improves the success rate of clamping the mop.

[0040] As shown in FIG. 5, Figure 5As shown, the connecting position of the lower end of the bidirectional driving rope and the driving slider deviates from the middle position of the mop plate length direction, the side of the hinged piece away from the extension direction of the lower end of the bidirectional driving rope is provided with a driving rope guide wall 61, and the driving slider is provided with a driving rope guide groove 74 along the length direction.

[0041] The driving rope guide wall and the driving rope guide groove are both used for limiting the activity range of the bidirectional driving rope, so as to avoid the invalid bending of the bidirectional driving rope and affect the transmission of the thrust. Specifically, the bending of the bidirectional driving rope at the position of the hinged piece is effective bending, so that the mop rod can be conveniently rotated relative to the mop plate, and the mop plate can conveniently drive the mop to clean various low and corner positions. In addition to cooperating with the rotation of the hinged piece position, the bending of the bidirectional driving rope at other positions will affect the transmission of the thrust between the transmission joint and the driving slider, so the driving rope guide wall and the driving rope guide groove are arranged at the positions where the bidirectional driving rope is easy to bend to limit the bidirectional driving rope.

[0042] The driving rope interface is a limiting step mouth formed on the side surface of the transmission joint, and after the transmission joint is installed in the connecting sleeve, the connecting part of the upper end of the bidirectional driving rope is limited in the driving rope interface.

[0043] The driving rope connecting mouth and the driving rope guide groove form a limiting step part at the adjacent position; the mop plate comprises an upper plate and a lower plate fixed opposite to the lower end of the upper plate; after the connecting part of the lower end of the bidirectional driving rope is installed in the driving rope connecting mouth, it is limited between the upper plate and the lower plate. The lower plate is provided with a sliding groove 34 slidably connected with the sliding arm 41.

[0044] The connecting part of the bidirectional driving rope is installed from the side surface of the transmission joint into the driving rope interface, and after the transmission joint is installed in the connecting sleeve, the connecting part of the upper end of the bidirectional driving rope is limited in the driving rope interface and cannot be separated, so that the installation mode does not need additional fixing parts to assist the connection, and the installation is facilitated. The connection of the connecting part of the lower end of the bidirectional driving rope and the driving slider is the same.

[0045] As shown in the figure, Figure 4 As shown, the lower end of the connecting sleeve 2 is provided with a rotation limiting part 23 near the side of the connecting part of the lower end of the bidirectional driving rope, and the rotation limiting part limits the rotation range between the connecting sleeve and the hinged piece to 0-120 degrees. If the connecting sleeve rotates too much to the side of the connecting part of the lower end of the bidirectional driving rope, the connecting part of the lower end of the bidirectional driving rope will slide, which will cause the sliding convex head to be separated from the positioning groove, and the clamping opening in the clamping state will be accidentally opened, so that the mop and the mop plate are separated.

[0046] The driving slider is provided with an elastic arm 72, and the sliding protrusion is arranged on the elastic arm and away from the driving slider. The elastic arm provides appropriate elastic force, so that the mop cloth clamped by the clamping opening can be clamped well regardless of whether it is thin or thick.

[0047] The lower end of the movable clamping member is provided with a second clamping tooth 40. When the clamping opening is in the open state, the lower end of the second clamping tooth is lower than or flush with the lower end surface of the mop plate. This design is to enable the second clamping tooth to be in good contact with the mop cloth, and during the process of the clamping opening from the open state to the closed state, the second clamping tooth can drive the mop cloth to move towards the mop plate and make the part of the mop cloth within the range of the clamping opening arch upwards, and then be clamped in the closed clamping opening.

[0048] When the clamping opening is in the closed state, the lower end of the second clamping tooth is flush with or higher than the lower end surface of the mop plate. This design makes the second clamping tooth not in contact with the ground when the mop with cloth mop is used to clean the ground, avoiding the abrasion or scratch of the second clamping tooth. As long as the sliding arm is designed to be slightly curved in an arc shape, the above-mentioned function can be achieved.

[0049] In addition, the side surface of the lower end of the mop plate towards the movable clamping member is provided with a first clamping tooth 33 extending towards the horizontal direction. When the clamping opening is in the closed state, the friction between the first clamping tooth and the mop cloth, or the embedding of the first clamping tooth into the mop cloth makes the mop cloth not easy to be separated from the clamping opening, so that the mop cloth can be kept in a stable state during the cleaning process of the mop with cloth.

[0050] In the initial state, the clamping opening is in the closed state. When one hand holds the connecting sleeve and the other hand holds the mop rod and pulls it upwards, the positioning buckle 12 on the transmission joint is separated from the lower positioning hole 22 and then slides to be clamped with the upper positioning hole 21, and at the same time, the transmission joint pulls the driving slider through the bidirectional driving rope 5 to slide to the left, and then the sliding protrusion cooperates with the transmission inclined sliding groove to drive the two movable clamping members 4 to move away from the mop plate, so that the clamping opening is opened. Figure 3

[0051] Then, the mop cloth is laid flat on the flat ground or table top, the mop plate is placed on the mop cloth, and the mop rod is pushed down to drive the transmission joint 11 to move downwards, the positioning buckle 12 is separated from the upper positioning hole 21 and then slides to be clamped with the lower positioning hole 22, and at the same time, the transmission joint pushes the driving slider through the bidirectional driving rope 5 to move to the right from the state of Figure 3 to the state of Figure 4 , and then the sliding protrusion cooperates with the transmission inclined sliding groove to drive the two movable clamping members 4 to move close to the mop plate, so that the clamping opening is closed and clamps the mop cloth.

[0052] As shown in Figure 8 and Figure 9 ​As shown, in other embodiments, the mop plate upper end is provided with a hand pushing sliding block 8, the mop plate upper end is provided with a strip-shaped opening, and the hand pushing sliding block is fixedly connected with the driving sliding block through a connecting piece penetrating through the strip-shaped opening.
