Description

Technical Field

[0001] This utility model relates to the field of household flat mop technology, and in particular to a flat mop that can be unlocked and clamped with one hand. Background Technology

[0002] A flat mop is a common household cleaning tool, which usually includes a mop handle and a mop head. The mop head has retractable cloth grippers on both sides, which are used to grip the cleaning cloth. The upper end of the mop handle is the grip end, which the user can usually hold to mop the floor.

[0003] Currently, some flat mops on the market use a twisted rod drive. They transmit power to the cloth clamping claws by the axial displacement of the inner and outer rods, causing them to open. Therefore, these flat mops require both hands to hold the inner and outer rods respectively, moving the inner rod upwards relative to the outer rod. The rotation of the twisted rod then causes the cloth clamping claws to unfold outwards. Therefore, a flat mop could be designed where the operator can control the opening of the cloth clamping claws with one hand at the gripping end of the mop handle. Once the clamping claws are open, pressing down on the entire mop handle and head with one hand allows the operator to grab the cleaning cloth onto the mop head. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The problem to be solved by this utility model is to provide a flat mop that can be unlocked and clamped with one hand, so as to overcome the defects in the prior art.

[0006] (II) Technical Solution

[0007] To solve the aforementioned technical problem, this utility model provides a flat mop with one-handed operation for unlocking and clamping the mop, including a mop handle and a mop plate. Clamping plates are movably arranged on both sides of the mop plate. A telescopic part is provided between the mop handle and the mop plate, allowing the mop handle to move closer to or further away from the mop plate. The clamping plates are drivenly connected to the mop handle via the telescopic part. A switch is provided on one side of the upper end of the mop handle at the gripping position. Elastic elements for driving the clamping plates and the telescopic part to unfold are provided within the telescopic part and / or the mop plate. The telescopic part is equipped with... A latch is used to keep the mop handle pressed down and the clamping plate clamping the cloth. In use, the switch is controlled with one hand to drive the latch to release the locking of the telescopic part, and the elastic element causes the mop handle to rise and the clamping plate to unfold to both sides. When clamping the cloth, the mop plate is placed on the cleaning cloth to be clamped, and the mop handle is pressed down with one hand. The movement of the telescopic part causes the clamping plates on both sides to move into the mop plate until the clamping plates clamp the cleaning cloth. At this time, the latch relocks the telescopic part.

[0008] In this design, the extension of the telescopic section primarily refers to raising the mop handle away from the mop plate. A switch is located at the grip position of the mop handle; a single-handed touch of the switch unlocks the latch, causing the clamping plate to extend outwards while the mop handle is in the raised position. Similarly, a single-handed downward press of the mop handle switches the flat mop to the cloth-clamping mode, where the clamping plate grips the cleaning cloth. Therefore, this flat mop can be operated with one hand for both unlocking and cloth clamping. The elastic element in this design can be located separately at the telescopic section, at the clamping plate, or simultaneously at both locations.

[0009] In some embodiments, the telescopic part includes a driving member and a transmission member for driving the clamping plate. The driving member is disposed at the bottom of the mop handle and can be moved up and down in the axial direction of the mop handle. Pressing down on the driving member causes it to drive the transmission member, thereby causing the clamping plate to clamp the cleaning cloth.

[0010] In this design, the drive unit and transmission unit are connected in a transmission configuration. When the mop handle is pressed down, power is transmitted to the transmission unit to move the clamping plate into the mop handle to clamp the cleaning cloth. The locking buckle is usually located on the drive unit. The elastic element can be located below the drive unit, always providing an upward thrust to the drive unit and the mop handle.

[0011] In some embodiments, the mop handle includes multiple hollow tubes connected in sequence; a hand grip is provided at the first hollow tube section, the switch is provided on the hand grip or on one side of the hand grip, and the last hollow tube section is connected to the telescopic part; and / or, adjacent hollow tube sections are connected by threads or snaps, and the hollow tubes are metal tubes.

[0012] In this solution, to reduce the packaging size, the mop handle is designed as a multi-section hollow tube. The mop handle is usually designed as two sections, including a first hollow tube and a last hollow tube.

[0013] In some embodiments, the mop handle is provided with a drive mechanism that is linked to the switch and the latch, the drive mechanism including a connecting rod or a pull rope.

[0014] In this design, the switch can transmit power to the latch via a linkage or pull rope to unlock it. At this point, the mop handle can be lifted and the clamping plate can be pushed outwards via the elastic element.

[0015] In some embodiments, the drive mechanism includes a connecting rod disposed near the latch, and the drive mechanism further includes a drive rod disposed on the side of the switch; when the switch is pushed with one hand, the drive rod pushes the connecting rod to unlock the latch, and the mop handle is lifted and the clamping plate is unfolded to both sides by an elastic element; the end of the connecting rod and the end of the drive rod are connected by contact engagement or mutual snapping.

[0016] In this solution, the switch unlocks by pushing the latch through the drive rod and the connecting rod. The drive rod can be directly fastened to the connecting rod or it can be in contact with the rod. This solution prefers the contact connection method.

[0017] In some embodiments, the drive mechanism includes a pull rope, the lower end of which is connected to a lower drive rod. The switch causes the lower drive rod to press down on the connecting rod by moving the pull rope, thereby unlocking the latch.

[0018] The mop handle has a parallel first pin and a second pin inside. The lower end of the pull rope is fixed to the lower drive rod after passing around the first pin, and the upper end of the pull rope is fixed to the upper drive rod after passing around the second pin. The upper drive rod and the lower drive rod are arranged opposite to each other. In use, the switch is pushed with one hand, and the upper drive rod is pressed down to move the entire pull rope upward, while the lower drive rod moves downward.

[0019] In this design, the switch uses a pull rope to drive the lower drive rod to press down on the connecting rod, thereby unlocking the latch. The pull rope is wound around two pins, one above the other. The upper and lower drive rods are coaxial and opposite to each other. Therefore, pushing the switch downwards ultimately causes the lower drive rod to press down on the connecting rod, thus unlocking the latch.

[0020] In some embodiments, the latch is movably disposed on the drive member; a pressing portion is formed at the lower end of the connecting rod, the latch is provided with an elastic locking hook, and an oblique flange corresponding to the pressing portion is formed at the upper end of the elastic locking hook; the pressing portion presses down on the oblique flange to unlock the elastic locking hook.

[0021] The latch is also provided with a limiting flange, and the pressing part is provided with a limiting groove that cooperates with the limiting flange; a first spring is provided between the latch and the pressing part.

[0022] In this design, the latch forms an elastic hook and an oblique flange. The connecting rod presses down on the oblique flange, causing the elastic hook to move and unlocking the telescopic part. At this point, the elastic element can drive the drive element and mop handle upwards, while simultaneously causing the clamping plate to unfold outwards. The latch's limiting flange falls into the limiting groove of the pressing part, and its first spring is used to continuously push the connecting rod upwards, allowing the connecting rod, drive rod, and switch to reset upwards.

[0023] In some embodiments, the driving member is a top block disposed at the lower end of the mop handle, and the lower end of the top block is provided with a pushing driving part, which is drivenly connected to the clamping plate; pressing down the mop handle causes the top block to move downward, and the pushing driving part drives the clamping plate to retract inward.

[0024] The transmission component is an oblique protrusion directly disposed on the inner end of the clamping plate; or, the transmission component is a swing rod hinged to the mop plate, the swing rod being hinged to the clamping plate; or the transmission component is a swing rod hinged to the lower end of the top block, the swing rod being hinged to the clamping plate, in which case the pushing drive part is the hinge point between the top block and the swing rod.

[0025] In this design, the top block of the telescopic section is directly mounted at the lower end of the mop handle, allowing it to move up and down. The transmission component can be an oblique protrusion or a swing rod, designed so that when the top block moves downward, it can drive the clamping plate to move inward, thus clamping the cleaning cloth. The latch in this design can be locked onto the mop board.

[0026] In some embodiments, the elastic element includes a second spring disposed at the lower end of the drive member; and / or, the elastic element includes a third spring disposed between the two clamping plates.

[0027] In this design, the second spring is used to consistently provide an upward thrust to the drive component, and the third spring is used to push the clamping plate outward.

[0028] In some embodiments, the driving element is a driving sleeve disposed at the bottom of the mop handle; the driving sleeve is connected to the transmission element via a helical rod.

[0029] In this design, a spiral rod (i.e., a twisted rod structure) is used to drive the transmission components, which are rotatably mounted on the mop board.

[0030] In some embodiments, the transmission component is an eccentric swing shaft, and the clamping plate is provided with a groove adapted to the motion trajectory of the eccentric swing shaft.

[0031] Alternatively, the transmission component may be a transmission gear, and the clamping plate may be provided with a transmission rack that meshes with the transmission gear.

[0032] In this design, the transmission component can be an eccentric swing shaft or a transmission gear, both of which can be rotatably mounted on the mop board; when the mop handle is set perpendicular to the mop board, its drive sleeve, screw rod and transmission component are coaxially arranged.

[0033] In some embodiments, the mop board is slidably mounted with a sliding plate that cooperates with the eccentric swing shaft along its length direction. The eccentric swing shaft is used to drive the sliding plate to reciprocate. The sliding plate is provided with an oblique groove, and the clamping plate is provided with a sliding pin that cooperates with the oblique groove. When the sliding plate moves along the length direction of the mop board, it drives the clamping plate to unfold outward or retract inward.

[0034] In this design, multiple oblique grooves can be set at both ends of the sliding plate to make the force on both ends of the clamping plate uniform and the clamping more secure.

[0035] In some embodiments, the mop handle is fitted with an outer mop rod, which is hinged to the mop plate, and the mop handle can slide relative to the outer mop rod; when the clamping plate clamps the cleaning cloth, the latch locks against the inner cavity of the outer mop rod; when the switch is pushed with one hand, the latch is driven to disengage from the inner cavity of the outer mop rod, the mop handle is lifted and the clamping plate unfolds outward.

[0036] In this design, the mop handle is hinged to the outer mop rod, and its latch is locked inside the inner cavity of the outer mop rod. At this time, the mop handle is always in a downward state, and the clamping plate is always in a cloth-clamping state.

[0037] In some embodiments, the drive mechanism includes a pull cord; the drive element is a floating seat hinged to the lower end of the mop handle, and the latch is movably installed in the floating seat and used to lock the floating seat to the mop board; the upper end of the pull cord is directly connected to the switch, and the lower end of the pull cord is equipped with a pull cord wedge, which is vertically slidably installed on the floating seat; pulling the switch with one hand causes the pull cord to pull the pull cord wedge upward, which drives the latch to move horizontally and release the lock on the floating seat, causing the floating seat to rise.

[0038] In this solution, the driving component is a floating seat. The switch directly pulls the pull rope, which drives the lock to move through the pull rope inclined block to unlock the floating seat and release the mop plate. The elastic component drives the mop handle to rise while the clamping plate unfolds outward.

[0039] In some embodiments, the transmission component is a cam disc rotatably mounted on the mop board, and the inner side of the floating seat is provided with a guide portion corresponding to and cooperating with the cam disc; a sliding plate is slidably mounted on the mop board along its length direction, and a clamping plate is mounted on the sliding plate. The movement of the sliding plate causes the clamping plate to move and expand or contract along the width direction of the mop board; an eccentric pin is provided at the lower end of the cam disc and cooperates with the sliding plate; when the entire mop handle is pressed down with one hand, the floating seat moves downward, the cam disc rotates through the guide portion, and the sliding plate slides along the length direction of the mop board through the eccentric pin, causing the clamping plate to move inward and clamp the cleaning cloth.

[0040] In this design, the cam plate and the guide part of the floating seat work together to rotate the cam plate when the entire mop handle is pressed down, which drives the sliding plate to move. This causes the clamping plate to move inward to grasp and hold the cleaning cloth. At this time, the lock locks the floating seat onto the mop handle. Conversely, when the switch unlocks the lock by pulling the cord, the elastic element causes the cam plate to rotate in the opposite direction, lifting the floating seat and the mop handle. At this time, the clamping plate unfolds outward in sync.

[0041] In some embodiments, the transmission component is a gear that is laterally rotatably mounted inside the mop plate, and the floating seat is provided with a rack that meshes with the gear; a sliding plate is slidably mounted on the mop plate along its length direction, and a clamping plate is mounted on the sliding plate. The movement of the sliding plate causes the clamping plate to move and expand or contract along the width direction of the mop plate; the sliding plate is provided with meshing teeth that also mesh with the gear; when the entire mop handle is pressed down with one hand, the floating seat moves downward, causing the gear to rotate, which in turn causes the sliding plate to slide along the length direction of the mop plate, thereby causing the clamping plate to move inward and clamp the cleaning cloth.

[0042] In this design, the gears inside the mop handle engage with the rack and teeth of the floating seat and the sliding plate. When the entire mop handle is pressed down, the gears rotate, causing the sliding plate to move and the clamping plate to retract inward to hold the cleaning cloth. At this time, the latch locks the floating seat onto the mop handle. Conversely, when the switch unlocks the latch by pulling the cord, the elastic element causes the gears to rotate in the opposite direction, causing the floating seat and the mop handle to rise. At this time, the clamping plate expands outward synchronously.

[0043] In some embodiments, the elastic element is a fourth spring disposed at the side end of the sliding plate.

[0044] In this design, the elastic element is located on the side of the sliding plate along the length of the mop handle and is used to push the sliding plate to move in the opposite direction. The movement of the sliding plate causes the cam plate or gear to rotate, thereby enabling the clamping plate to unfold outward and the floating seat and mop handle to be lifted through the elastic element.

[0045] (III) Beneficial Effects

[0046] This utility model provides a flat mop with one-handed operation for unlocking and clamping the mop cloth. The switch is located at the grip position of the mop handle, allowing for one-handed operation to unlock the latch and unfold the clamping plate. At this point, the mop handle is in a raised position relative to the mop plate. Alternatively, the mop handle can be pressed down with one hand to grab and clamp the cleaning cloth onto the mop plate. Therefore, both opening the clamping plate and clamping the cloth can be done with one hand, and opening the clamping plate can be controlled with a single button, making operation simple and convenient. The mop handle can be a multi-section hollow tube connected sequentially for easy packaging and storage. The switch transmits power to the latch via a drive mechanism, which can be a pull rope or a linkage. The telescopic part includes a drive component located at the lower end of the mop handle and a transmission component for driving the clamping plate. An elastic element is used to lift the drive component and the mop handle while simultaneously unfolding the clamping plate outwards. Therefore, the elastic element can be located below the drive component or inside the mop plate, such as on the side of the sliding plate or directly between the two clamping plates.

[0072] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0073] See Figures 1 to 24 This utility model provides a flat mop that can be unlocked and clamped with one hand. The flat mop includes a mop handle 1 and a mop plate 2. Clamping plates 3 are movably arranged on both sides of the mop plate 2, and the clamping plates 3 can be unfolded or retracted relative to the mop plate 2. The mop handle 1 can move closer to or further away from the mop plate 2. When the mop handle 1 is in the raised, further-away position, its clamping plates 3 are in the unfolded state; when the mop handle 1 is in the pressed-down, closer-away position, its clamping plates 3 are in the retracted, clamping state. The clamping plates 3 are driven to the mop handle 1 via a telescopic part. A switch 4 is provided on one side of the upper gripping position of the mop handle 1. The telescopic part and / or the mop plate 2 are provided with elastic elements for driving the clamping plates 3 and the telescopic part to unfold. The telescopic part is provided with a latch 5 for keeping the mop handle 1 in the pressed-down state and simultaneously keeping the clamping plates 3 in the clamping state.

[0074] In use, the switch 4 is operated with one hand to drive the latch 5 to release the locking of the telescopic part. The elastic element causes the mop handle 1 to rise and the clamping plates 3 to unfold to both sides. When clamping a cleaning cloth, place the mop plate 2 on the cleaning cloth to be clamped, and press down on the mop handle 1 with one hand. The movement of the telescopic part causes the clamping plates 3 on both sides to move inward into the mop plate 2 until the clamping plates 3 clamp the cleaning cloth. At this time, the latch 5 locks the telescopic part again. The unfolding of the clamping plates 3 and the retracted clamping state of the clamping plates 3 can both be operated with one hand.

[0075] In some embodiments, such as Figure 1 and Figure 8 As shown, a scraper 51 is provided on one end of the mop board 2.

[0076] In some embodiments, such as Figure 1 and Figure 7 As shown, the mop handle 1 includes multiple hollow tubes connected in sequence; the hollow tubes include a first hollow tube 101 and a last hollow tube 102. A hand grip 103 is provided at the first hollow tube 101, and a switch 4 is provided on the hand grip 103. Of course, the switch 4 can also be provided near the hand grip 103 for one-handed operation. The last hollow tube 102 is connected to the telescopic part.

[0077] In this configuration, adjacent hollow tube sections are connected by threads or snap-fit ​​connections, and the hollow tubes are made of metal; in one example, such as Figure 7 As shown, the first hollow tube 101 and the last hollow tube 102 are connected by fasteners 104.

[0078] In some embodiments, the telescopic part includes a drive member 6 and a transmission member 7 for driving the clamping plate 3. The drive member 6 is located at the bottom of the mop handle 1 and can be moved up and down in the axial direction of the mop handle 1. Pressing down the drive member 6 causes it to drive the transmission member 7, thereby causing the clamping plate 3 to clamp the cleaning cloth.

[0079] In some embodiments, such as Figure 3 As shown, the elastic element includes a second spring 25 disposed at the lower end of the driving member 6. The second spring 25 always provides an upward thrust to the driving member 6. After the latch 5 is unlocked, the second spring 25 pushes the driving member 6 upward and drives the transmission member 7 to move, thereby causing the clamping plate 3 to unfold outward; or as shown Figure 13 or Figure 14 As shown, the elastic element includes a third spring 26 disposed between the two clamping plates 3. The third spring 26 always provides a pushing force to the clamping plates 3 to unfold outward. After the latch 5 is unlocked, the third spring 26 will push the clamping plates 3 to unfold and drive the driving element 6 to move upward.

[0080] In some embodiments, the mop handle 1 is provided with a drive mechanism that is linked to the switch 4 and the latch 5. The drive mechanism is used to realize the power transmission between the switch 4 and the latch 5. The drive mechanism includes a connecting rod 8 or a pull rope 10.

[0081] In some embodiments, such as Figure 2 , Figure 5 , Figure 8 , Figure 9 As shown, the drive mechanism drives the latch 5 to unlock via the connecting rod 8. The connecting rod 8 is located on the side close to the latch 5. The drive mechanism also includes a drive rod 9 located on the side of the switch 4. When the switch 4 is pushed with one hand, the drive rod 9 pushes the connecting rod 8 to unlock the latch 5, and the mop handle 1 is lifted and the clamping plate 3 is unfolded to both sides through the elastic element.

[0082] like Figure 5 As shown, the end of connecting rod 8 and the end of drive rod 9 are connected by contact engagement or mutual snap-fit. In this embodiment, the end of connecting rod 8 and the end of drive rod 9 are in contact engagement; as... Figure 2 As shown, the drive rod 9 is located inside the first hollow tube, and the connecting rod 8 is located inside the last hollow tube.

[0083] In some embodiments, such as Figure 11 and Figure 12 As shown, the drive mechanism unlocks the latch 5 by pulling the rope 10. The lower end of the rope 10 is connected to a lower drive rod 11. The switch 4, by moving the rope 10, causes the lower drive rod 11 to press down on the connecting rod 8, thus unlocking the latch 5. The lower drive rod 11 can be pressed down by pushing or pulling the switch 4. Figure 11 and Figure 12 As shown, in this embodiment, the lower drive rod 11 is pressed down by pushing the switch 4. The mop handle 1 is provided with a parallel first pin 12 and a second pin 13. The two pins are used for the pull rope 10 to pass through the cord. The pins can also be replaced by a cord guide wheel. The lower end of the pull rope 10 is fixed to the lower drive rod 11 after passing through the first pin 12. The upper end of the pull rope 10 is fixed to the upper drive rod 14 after passing through the second pin 13. The upper drive rod 14 is arranged opposite to the lower drive rod 11. The upper drive rod 14 and the lower drive rod 11 are respectively passed through the two pins. Therefore, pushing the upper drive rod 14 down will also drive the lower drive rod 11 to move down through the pull rope 10. In use, the switch 4 is pushed down with one hand, the upper drive rod 14 is pressed down, which drives the entire pull rope 10 to move upward, and the lower drive rod 11 to move downward. Pressing down the connecting rod 8 unlocks the latch 5.

[0084] like Figure 11 and Figure 12 As shown, the first pin 12 is fixed inside the mop handle 1 by the lower positioning sleeve 46, and the second pin 13 is fixed inside the mop handle 1 by the upper positioning sleeve 47. Figure 12 As shown, both the lower drive rod 11 and the upper drive rod 14 are provided with waist-shaped clearance grooves for clearance pins.

[0085] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the latch 5 is movably mounted on the drive member 6; the lower end of the connecting rod 8 forms a pressing part 15, and the latch 5 is provided with an elastic locking hook 16. The upper end of the elastic locking hook 16 forms an oblique flange 17 corresponding to the pressing part 15. The pressing part 15 presses down on the oblique flange 17, causing the elastic locking hook 16 to move inward to unlock; the latch 5 is also provided with a limiting flange 18, and the pressing part 15 is provided with a limiting groove 19 that cooperates with the limiting flange 18. In this embodiment, the upper surface of the limiting flange 18 is an oblique surface, and the limiting groove 19 of the connecting rod 8 can be inserted downward into the limiting flange 18 to cooperate with it; a first spring 20 is provided between the latch 5 and the pressing part 15. The first spring 20 is used to always provide an upward reset thrust to the connecting rod 8.

[0086] In some embodiments, such as Figure 13 and Figure 14 As shown, the driving component 6 is a top block 21. A pushing driving part 22 is provided at the lower end of the top block 21. The pushing driving part 22 is driven to connect with the clamping plate 3. When the mop handle 1 is pressed down, the top block 21 moves downward, and the pushing driving part 22 drives the clamping plate to retract inward. The two clamping plates 3 are driven to unfold outward by the third spring 26.

[0087] In one example, such as Figure 13 As shown, the transmission component 7 is an oblique protrusion 23 directly mounted on the inner end of the clamping plate 3. The pressing block 21 will drive the oblique protrusion 23 to move inward, thereby achieving the clamping of the cleaning cloth by the two clamping plates 3. In another example, as... Figure 14 As shown, the transmission component 7 is a swing rod 24 hingedly installed inside the mop plate 2. The swing rod 24 is hinged to the clamping plate 3. The pressing block 21 will drive the two swing rods 24 to swing inward, thereby driving the two clamping plates 3 to move inward to clamp the cleaning cloth. In another example, as... Figure 24 The transmission component 7 is a swing rod 24 hinged to the lower end of the top block 21. The swing rod 24 is hinged to the clamping plate. At this time, the pushing drive part 22 is the hinge point between the top block 21 and the swing rod 24. The clamping plate 3 is hinged to the swing rod 24 at less than 90 degrees. When the mop handle 1 is pressed down, the swing rod 24 swings to the side with a smaller angle and drives the clamping plate 3 to retract inward.

[0088] In some other embodiments, the driving component 6 is a driving sleeve 27 disposed at the bottom of the mop handle 1; the driving sleeve 27 is connected to the transmission component 7 through a spiral rod 28. In this embodiment, the transmission component 7 is rotatably mounted on the mop plate 2, and its driving sleeve 27 transmits power to the transmission component 7 through the spiral rod 28 (i.e., the twisted rod structure).

[0089] In one example, such as Figure 3 and Figure 6 As shown, the transmission component 7 is an eccentric swing shaft 29, and the clamping plate 3 is provided with a groove 31 that is adapted to the movement trajectory of the eccentric swing shaft 29.

[0090] In some other embodiments, the mop plate 2 is slidably mounted with a sliding plate 30 that cooperates with an eccentric swing shaft 29 along its length. The eccentric swing shaft 29 is placed in the matching groove 48 of the sliding plate 30. The eccentric swing shaft 29 is used to drive the sliding plate 30 to reciprocate along the length of the mop plate 2. The sliding plate 30 is provided with an inclined groove 31. The clamping plate 3 is provided with a sliding pin 32 that cooperates with the inclined groove 31. The function of the inclined groove 31 and the sliding pin 32 is to switch the moving force in the length direction of the mop plate 2 to the moving force in the width direction of the mop plate 2. When the sliding plate 30 moves along the length direction of the mop plate 2, it drives the clamping plate 3 to unfold outward (i.e., in the width direction of the mop plate 2) or retract inward.

[0091] In another example, such as Figure 9 and Figure 10 As shown, the transmission component 7 is a transmission gear 33, and the clamping plate 3 is provided with a transmission rack 34 that meshes with the transmission gear 33. The rotation of the transmission gear 33 directly drives the clamping plate 3 to move, expand, or retract through the transmission rack 34.

[0092] In some embodiments, such as Figure 1 and Figure 2 As shown, the mop handle 1 is fitted with an outer mop rod 35, which is hinged to the mop plate 2 via a first universal joint 49. The mop handle 1 can slide relative to the outer mop rod 35. When the clamping plate 3 clamps the cleaning cloth, the latch 5 locks against the inner cavity 36 of the outer mop rod 35. When the switch 4 is pushed with one hand, the latch 5 is driven to disengage from the inner cavity 36 of the outer mop rod 35, the mop handle 1 is lifted and the clamping plate 3 unfolds outward.

[0093] In some embodiments, such as Figures 15-23 As shown, the drive mechanism also controls the unlocking of the latch 5 by pulling the cord 10, the difference being that it unlocks by pulling the switch 4. The drive component 6 is a floating seat 37 hinged to the lower end of the mop handle 1, and the latch 5 is movably installed in the floating seat 37 and used to lock the floating seat 37 onto the mop board 2; as shown Figure 16 , Figure 17 and Figure 19 As shown, the upper end of the pull rope 10 is directly connected to the switch 4, and the lower end of the pull rope 10 is equipped with a pull rope inclined block 38. The pull rope inclined block 38 is vertically slidably mounted on the floating seat 37, and the pull rope 10 passes through the floating seat 37 and connects to the pull rope inclined block 38. Pulling the switch 4 with one hand causes the pull rope 10 to pull the pull rope inclined block 38 upward, which drives the lock 5 to move horizontally and release the lock on the floating seat 37, causing the floating seat 37 to rise. Figure 19As shown, a fifth spring 52 is provided on one side of the latch 5. The fifth spring 52 is used to continuously push the latch 5 to lock the floating seat 37 onto the mop board 2.

[0094] like Figure 15 As shown, the lower end of the mop handle 1 is hinged to the floating seat 37 via the second universal joint 50.

[0095] In some embodiments, such as Figure 16 and Figure 21 As shown, the elastic element is a fourth spring 45 located at the side end of the sliding plate 30. The fourth spring 45 pushes the sliding plate 30 to slide along the length of the mop plate 2, causing the clamping plates 3 on both sides to unfold.

[0096] In one example, such as Figures 15-20 As shown, the transmission component 7 is a cam disc 39 rotatably mounted on the mop plate 2, and the inner side of the floating seat 37 is provided with a guide part 40 that corresponds to and cooperates with the cam disc 39, such as... Figure 16 and Figure 20 As shown, the rotation of the cam disk 39 will push the floating seat 37 to move upward; the mop plate 2 is slidably mounted with a sliding plate 30 along its length direction, and the clamping plate 3 is mounted on the sliding plate 30. The movement of the sliding plate 30 will cause the clamping plate 3 to move and expand or contract along the width direction of the mop plate 2.

[0097] like Figure 20 As shown, the lower end of the cam disk 39 is provided with an eccentric pin 41 that cooperates with the sliding plate 30; when the entire mop handle 1 is pressed down with one hand, the floating seat 37 moves downward, and the cam disk 39 rotates through the guide part 40. The eccentric pin 41 drives the sliding plate 30 to slide along the length of the mop handle 2, which in turn drives the clamping plate 3 to move inward and clamp the cleaning cloth.

[0098] like Figure 16 As shown, the mop plate 2 includes an upper shell 201 and a lower shell 202. The floating seat 37 is movably mounted on the upper shell 201, and the cam plate 39 is rotatably mounted inside the lower shell 202.

[0099] In another example, such as Figures 21-23 As shown, the transmission component 7 is a gear 42 that is horizontally rotatably installed inside the mop plate 2. The floating seat 37 is provided with a rack 43 that meshes with the gear 42. The mop plate 2 is slidably installed with a sliding plate 30 along its length direction. The clamping plate 3 is installed on the sliding plate 30. The movement of the sliding plate 30 causes the clamping plate 3 to move and expand or contract along the width direction of the mop plate 2. The sliding plate 30 is provided with meshing teeth 44 that also mesh with the gear 42. When the entire mop handle 1 is pressed down with one hand, the floating seat 37 moves downward, causing the gear 42 to rotate, which drives the sliding plate 30 to slide along the length direction of the mop plate 2, thereby driving the clamping plate 3 to move inward and clamp the cleaning cloth.

[0100] In some embodiments, the clamping plate 3 includes a support arm 301 that cooperates with the sliding plate 30 and a gripping claw 302 that is hinged to the support arm 301. The support arm 301 drives the gripping claw 302 to unfold or retract. The gripping claw 302 is used to directly contact the cleaning cloth for gripping.

[0101] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
