[0002] CN222622903U discloses a cloth-clamping mop, which includes a mop handle and a mop head. The mop head includes a base plate and a panel fixed to the base plate. Two cloth-clamping plates are also provided between the base plate and the panel, and the two cloth-clamping plates extend from the sides of the base plate and the panel respectively. A clamping area for the mop cloth is formed between the outer edge of the cloth-clamping plate and the side edge of the base plate. The cloth-clamping plates can move inward to clamp the mop cloth in the clamping area. The mop head is provided with a mop handle that can be pressed down. The lower end of the mop handle is connected to a linkage drive mechanism. When the mop handle is pressed down, the linkage drive mechanism drives the cloth-clamping plates to retract inward, thereby clamping the mop cloth in the clamping area.

[0003] Its drawbacks include the complexity of its linkage drive mechanism, which makes it difficult to operate smoothly. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of existing cloth clamping mops, this utility model provides a cloth clamping mop with simple structure and smooth operation.

[0005] The technical solution of this utility model to solve its technical problem is: a cloth clamping mop, including a mop handle and a mop head;

[0006] The mop head includes a base plate and a panel fixed to the base plate;

[0007] Two clamping plates are provided between the base plate and the panel, and the two clamping plates extend from the sides of the base plate and the panel respectively. The outer edge of the clamping plate and the side edge of the base plate form a clamping area for the mop cloth. The clamping plate can move inward to clamp the mop cloth under the base plate in the clamping area.

[0008] The panel is provided with a raised lifting chamber, and the lifting chamber is provided with a lifting seat that can be raised and lowered vertically. A return elastic device is provided between the base plate and the lifting seat, and the return elastic device applies an upward restoring force to the lowered lifting seat.

[0009] The lifting seat has a protruding drive head on its side, and the fabric clamping plate has a raised drive seat. The drive seat has an inclined groove that slopes from top to bottom towards the outside of the fabric clamping plate. The drive head can be located in the inclined groove and slide relative to it. When the lifting seat descends, the fabric clamping plate moves inward under the downward driving force of the drive head.

[0010] The fabric clamp also includes a locking and unlocking mechanism that locks the lifting seat after it is lowered to keep it in a low position and releases the locking of the lifting seat. After the locking and unlocking mechanism releases the locking of the lifting seat, the lifting seat automatically returns to its original position under the action of the return elastic device.

[0011] Furthermore, the lifting seat is provided with a sliding cavity, and the first end of the sliding cavity has an opening formed on the wall surface of the lifting seat.

[0012] The locking and unlocking mechanism includes a movable locking plate located in the sliding cavity, a locking rod located on the base plate, and an unlocking button slidably located on the wall of the lifting chamber.

[0013] An external elastic device is provided between the tail of the locking plate and the bottom wall of the second end of the sliding cavity. Under the action of the external elastic device, the head of the locking plate can extend out of the lifting seat through the opening. The locking plate has a locking opening. The lifting seat has a vertical locking rod channel that extends to the top of the sliding cavity. The locking opening and the locking rod channel are opposite to each other and intersect in the horizontal direction, so that the part of the locking plate behind the locking opening is located in the locking rod channel to form an intersecting part.

[0014] The unlock button is positioned opposite the head of the lock plate.

[0015] The upper end of the locking rod is provided with a locking hook that bends toward the second end of the sliding cavity, and the locking rod extends into the locking rod channel;

[0016] When locked, after the lifting seat descends, the upper end of the locking rod pushes the locking plate toward the second end of the sliding cavity, so that the upper end of the locking rod extends into and passes through the lock opening. After the locking plate is reset, the locking hook hooks onto the upper surface of the locking plate.

[0017] When unlocking, press the unlock button to push the lock plate, so that the lock hook at the upper end of the lock rod disengages from the lock plate, and the lifting seat rises back to its original position under the action of the return elastic device.

[0018] Furthermore, the top of the locking hook has a slope facing the interlocking portion, and when the upper end of the locking bar passes through the lock opening, the slope pushes the interlocking portion open.

[0019] The sliding cavity is horizontally disposed in the lifting seat, and the locking plate can move horizontally along the sliding cavity.

[0020] Furthermore, the side of the lifting seat is provided with a receiving groove, and the driving head is disposed in the receiving groove. The shape of the receiving groove is adapted to the shape of the driving seat, so that the driving seat is located in the receiving groove after the lifting seat is lowered.

[0021] Furthermore, the drive head is a slanted block shape that matches the width and inclination angle of the slanted groove, and / or the drive head is cylindrical.

[0022] Furthermore, the lifting chamber is located in the center of the panel, and the drive seat is located inside the fabric clamping plate.

[0023] Furthermore, a connector is hinged to the lifting seat, and the lower end of the mop handle is hinged to the connector. The hinge direction of the lifting seat and the connector is perpendicular to the hinge direction of the mop handle and the connector. When the mop handle is pressed down, it drives the connector and the lifting seat to descend.

[0024] Furthermore, the lower end of the mop handle has an upper interlayer, and the connector extends into the upper interlayer and is hinged to the mop handle;

[0025] The upper end of the lifting seat has a lower interlayer, and the connector extends into the lower interlayer and is hinged to the lifting seat.

[0051] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0052] Reference Figures 1-22 A cloth-clamping mop includes a mop handle 1 and a mop head 2.

[0053] The mop head 1 includes a base plate 3 and a panel 4 fixed to the base plate 3. Two clamping plates 5 are also provided between the base plate 3 and the panel 4, extending from opposite sides of the base plate 3 and the panel 4 respectively. A clamping area for the mop cloth is formed between the outer edge of the clamping plate 5 and the side edge of the base plate 3. The clamping plates 5 can move inward to clamp the mop cloth under the base plate within the clamping area. In one embodiment, the base plate 3 and the panel 4 are connected by screws. The clamping plate 5 has a relief groove 6, and the screw is located in the relief groove 6 so that the clamping plate 5 is not obstructed by the screw when moving inward.

[0054] In one embodiment, both the outer edge of the clamping plate 5 and the side edge of the base plate 3 are provided with clamping teeth 7. The clamping teeth 7 allow the mop cloth to be clamped more tightly when the outer edge of the clamping plate 5 and the side edge of the base plate 3 clamp it. A better embodiment is that the outer edge of the clamping plate 5 has a downwardly folded clamping edge 8, and the clamping teeth 7 are located on the inner surface of the clamping edge 8. Figure 2 and 16 As shown.

[0055] The inward movement of the fabric clamping plate 5 is driven by a drive mechanism. The panel 4 has a raised lifting chamber 9, preferably located in the center of the panel 4. The drive mechanism for moving the fabric clamping plate 5 inward includes a vertically movable lifting seat 10 located within the lifting chamber 9. A return elastic device is provided between the base plate 3 and the lifting seat 10. This return elastic device applies an upward restoring force to the lifting seat 10 after it descends, causing it to automatically return to its original position. The elastic return device typically uses a return spring 11. The lower end of the return spring 11 rests against the base plate 3, and the upper end of the return spring 11 rests against the lifting seat 10. To ensure that the return spring 11 remains as vertical as possible during compression and rebound, a sleeve can be provided on the base plate. The lower part of the return spring 11 is fitted onto the sleeve, and a spring groove is provided on the bottom surface of the lifting seat 10, with the upper part of the return spring 11 extending into the spring groove.

[0056] The lifting seat 10 has a protruding drive head 12 on its side, and the fabric clamping plate 5 has a protruding drive seat 13. The drive seat 13 has an inclined groove 14 that slopes from top to bottom towards the outside of the fabric clamping plate. The drive head 13 can be located in the inclined groove 14 and slide relative to it. When the lifting seat 10 descends, the fabric clamping plate 5 moves inward under the downward driving force of the drive head 12. Preferably, the drive head 12 is a diagonal strip block that matches the width and inclination angle of the inclined groove 14, such as... Figure 5 As shown, the inclined block-shaped drive head 12 can slide smoothly along the inclined groove 14. Of course, the drive head 12 can also be, for example, cylindrical, which would make its sliding along the inclined groove 14 even smoother.

[0057] In one embodiment, the drive seat 13 is located inside the fabric clamping plate 5, and the side of the lifting seat 10 is provided with a receiving groove 15. The drive head 12 is disposed in the receiving groove 15. The shape of the receiving groove 15 is adapted to the shape of the drive seat 13, so that after the lifting seat 10 is lowered, the drive seat 13 is located in the receiving groove 15, so that the structure is more compact.

[0058] The lifting seat 10 is hinged to a connector 16, and the lower end of the mop handle 1 is hinged to the connector 16. The hinge direction of the lifting seat 10 and the connector 16 is perpendicular to the hinge direction of the mop handle 1 and the connector 16. This bidirectional hinge structure allows the mop handle 1 and the mop head 2 to rotate in multiple directions, facilitating mopping operations. When the mop handle 1 is pressed down, it causes the connector 16 and the lifting seat 10 to descend.

[0059] In the diagram, the lifting seat 10 and the connector 16 are longitudinally hinged (i.e., the hinge axis between them is along the length of the mop head), and the mop handle 1 and the connector 16 are laterally hinged (i.e., the hinge axis between them is along the width of the mop head). In one embodiment, the specific hinge method between the lifting seat 10 and the connector 16, and the specific hinge method between the mop handle 1 and the connector 16, is as follows: the lower end of the mop handle 1 has an upper interlayer 17, and the connector 16 extends into the upper interlayer 17 and is hinged to the mop handle 1; the upper end of the lifting seat 10 has a lower interlayer 18, and the connector 16 extends into the lower interlayer 18 and is hinged to the lifting seat 10. This structure allows the lifting seat 10, the connector 16, and the mop handle 1 to be substantially aligned in a straight line.

[0060] In one embodiment, the top surface of the upper interlayer 17 is provided with a raised positioning rib 19, and the upper end of the connector 16 is provided with a positioning groove 20, wherein the positioning rib 19 can be embedded in the positioning groove 20; or, the top surface of the upper interlayer is provided with a positioning groove, and the upper end of the connector is provided with a raised positioning rib, wherein the positioning rib can be embedded in the positioning groove. In actual mopping, the mop handle 1 and the connector 16 are usually aligned on the same straight line. Thus, when the mop handle 1 rotates to be aligned with the connector 16, the two can be positioned by the interaction of the positioning rib 19 and the positioning groove 20, making it easy to maintain this position.

[0061] After the lifting seat 10 descends, the clamping plate 5 moves inward to clamp the mop cloth. After the lifting seat 10 descends, a locking mechanism is also needed to lock the lifting seat 10 in its low position (to maintain the clamped mop cloth) and release the lock on the lifting seat 10. After the locking mechanism releases the lock on the lifting seat 10, the lifting seat 10 automatically returns to its original position under the action of the return elastic device. At this time, the clamping plate 5 also moves outward to its original position, allowing the mop cloth to be removed.

[0062] In one embodiment, the lifting seat 10 is provided with a sliding cavity 21. An opening is formed at the first end of the sliding cavity 21 on the wall of the lifting seat 10. The specific structure of the locking / unlocking mechanism includes a movable locking plate 22 disposed in the sliding cavity 21, a locking rod 27 disposed on the base plate 3, and an unlocking button 30 slidably disposed on the wall of the lifting chamber 9. Preferably, the sliding cavity 21 is horizontally disposed in the lifting seat 10, and the locking plate 22 is capable of horizontal movement along the sliding cavity 21.

[0063] An external elastic device is provided between the tail of the locking plate 22 and the bottom wall of the second end of the sliding cavity 21. Under the action of the external elastic device, the head of the locking plate 22 can extend out of the lifting seat through the opening. The external elastic device is usually an external compression spring 23. A locking opening 24 is provided on the locking plate 22. A vertical locking rod channel 25 is provided in the lifting seat 10 and the locking rod channel 25 extends to the top of the sliding cavity 21. The locking opening 24 and the locking rod channel 25 are opposite to each other and intersect in the horizontal direction, so that the part of the locking plate behind the locking opening 24 is located in the locking rod channel 25 to form an intersecting part 26.

[0064] The upper end of the locking rod 27 is provided with a locking hook 28 bent toward the second end of the sliding cavity 21, and the locking rod 27 extends into the locking rod channel 25. When locking, after the lifting seat 10 descends, the upper end of the locking rod 27 pushes the locking plate 22 toward the second end of the sliding cavity 21, so that the upper end of the locking rod 27 extends into and passes through the lock opening 24. After the lock plate 22 is reset, the locking hook 28 hooks onto the upper surface of the lock plate 22. In one embodiment, the top of the locking hook 28 has a slope 29 facing the interlacing part 26. When the upper end of the locking rod 27 passes through the lock opening 24, the slope 29 pushes the interlacing part 26 open. After the upper end of the locking rod 27 passes through the lock opening 24, the lock plate 22 is reset under the action of the outer top elastic device, so that the locking hook 28 hooks onto the upper surface of the lock plate 22.

[0065] The unlocking button 30 is slidably disposed on the wall of the lifting chamber 9, i.e., the wall of the lifting chamber 9 is also provided with a through hole, and the unlocking button 30 is slidably disposed in the through hole. The unlocking button 30 is disposed opposite to the head of the locking plate 22, preferably directly opposite the head of the locking plate 22. When unlocking, pressing the unlocking button 30 pushes the locking plate 22. At this time, the locking hook 28 at the upper end of the locking rod 27 disengages from the locking plate 22. Under the action of the return elastic device, the lifting seat 10 rises back to its original position. During the process of the lifting seat 10 rising back to its original position, the fabric clamping plate 5 is driven to move outward and reset under the upward driving force of the drive head 12.
