Description

Technical Field

[0001] This utility model belongs to the field of cleaning products technology, and in particular relates to a flat mop. Background Technology

[0002] Existing folding flat mops suffer from numerous structural design flaws. Some mops have unstable folding mechanisms, making the mop plate prone to accidental folding during use, impacting cleaning efficiency and user experience. Others require multiple cumbersome steps to fold or unfold, causing inconvenience for users. Furthermore, most mops lack reliable locking and anti-rotation mechanisms, failing to effectively secure the mop plate in both unfolded and folded states, resulting in significant space requirements when stored and mop plate wobbling during use. These issues limit the convenience and practicality of flat mops in users' daily lives. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a flat mop to meet the needs of users.

[0004] To achieve the above objectives, this utility model provides a flat mop, including a mop plate. The mop plate includes a main plate and side plates pivotally connected to both sides of the main plate. The mop plate has a flattened state and a folded state. The side plates include anti-rotation grooves, each including an open end facing the main plate.

[0005] Two-way locking module, including

[0006] Two retractable anti-rotation pins are symmetrically arranged on both sides of the main board. The anti-rotation pins are adapted to extend into the anti-rotation groove to prevent the side plate from flipping.

[0007] A linkage mechanism adapted to respond to external operating force to drive the two anti-rotation pins to retract synchronously to disengage from the anti-rotation groove;

[0008] A reset elastomer, which is adapted to drive the anti-rotation pin to re-extend into the anti-rotation groove via the linkage mechanism;

[0009] The status maintenance mechanism includes:

[0010] A first locking part is disposed on the side plate and moves with the side plate;

[0011] The second locking part, which is disposed in the linkage mechanism, in the flattened state, abuts against the first locking part as the anti-rotation pin retracts, thereby temporarily restricting the anti-rotation pin from rebounding. The first locking part separates from the second locking part as the side plate folds down, thereby allowing the reset elastic body to drive the anti-rotation pin to reset.

[0012] Preferably, the slide includes a medium-long axis l arranged along its length direction and a medium-short axis h arranged along its width direction. The side plate rotates about a pivot axis α, which is parallel to one of the medium-long axis l and the medium-short axis h. The anti-rotation pin is arranged perpendicular to the pivot axis α. The unlocking operation part is adapted to simultaneously drive the two transmission units to move synchronously toward the center in a direction perpendicular to the pivot axis α.

[0013] Preferably, the flat mop further includes an unlocking operation part adapted to receive external operating force. The linkage mechanism includes a first transmission unit and a second transmission unit. The unlocking operation part is disposed on the main board and is adapted to simultaneously directly contact the first transmission unit and the second transmission unit to transmit external operating force.

[0014] Preferably, the first transmission unit includes a transmission body, a first transmission arm, and a first driven arm connected in sequence, and the second transmission unit includes a transmission body, a second transmission arm, and a second driven arm connected in sequence, wherein:

[0015] The unlocking operation unit includes two symmetrically arranged driving inclined surfaces. The first transmission unit includes a first driven inclined surface, and the second transmission unit includes a second driven transmission inclined surface. The two driving inclined surfaces simultaneously slide and cooperate with the first driven inclined surface and the second driven inclined surface, respectively, to convert the vertical operating force into the horizontal driving force, thereby achieving efficient force transmission, reducing operating resistance, and making the unlocking process easier and smoother.

[0016] Alternatively, the unlocking operation unit includes a drive gear, the first transmission unit includes a first driven rack, and the second transmission unit includes a second driven rack. The drive gear simultaneously meshes with the first driven rack and the second driven rack, respectively, converting the circular motion of the unlocking operation unit into the linear motion of the linkage mechanism. This provides a precise transmission ratio, ensures that the anti-rotation pins on both sides move synchronously, and improves the consistency and reliability of unlocking and locking.

[0017] Preferably, the first driven arm is arranged in a direction perpendicular to the pivot axis α, and the second driven arm is arranged parallel to the first driven arm. The first transmission arm and the second transmission arm are adapted to guide the first driven arm and the second driven arm to be misaligned along the extension direction of the pivot axis α, thereby optimizing the transmission path, avoiding interference between transmission units, making the structure more compact, and ensuring the effectiveness of force transmission.

[0018] Preferably, the flat mop also includes an unlocking operation part adapted to receive external operating force. The linkage mechanism includes two transmission units, which are centrally symmetrical about the center of the main board. At least one of the side plates is provided with the unlocking operation part. The unlocking operation part is adapted to transmit external operating force to one of the two transmission units through the anti-rotation pin. The two transmission units are connected by transmission, providing multiple operating modes. Users can choose the unlocking operation part on either side plate to unlock according to actual needs, improving the flexibility of use.

[0019] Preferably, the transmission unit includes a transmission body, a first transmission arm and a second transmission arm extending outward from one end of the transmission body, a first driven arm connected to the first transmission arm, and a second driven arm connected to the second transmission arm, wherein:

[0020] The first driven arm includes a first rack, and the second driven arm includes a second rack. The first rack and the second rack mesh with the same transmission gear, which is pivotally connected to the main board; or, the second driven arm and the second driven arm are pivotally connected to both ends of the same transmission link, which is pivotally connected to the main board.

[0021] Preferably, the first driven arm is arranged in a direction perpendicular to the pivot axis α, the second driven arm is arranged parallel to the first driven arm, and the first rack and the second rack are arranged facing each other.

[0022] Preferably, in the same side plate, the unlocking operation unit is connected to the anti-rotation pin via a transmission slider, and the unlocking operation unit is adapted to drive the transmission slider into the anti-rotation groove and push open the anti-rotation pin, wherein:

[0023] The unlocking operation unit includes a driving ramp, and the transmission slider includes a driven ramp adapted to engage with the driving ramp; or, the unlocking operation unit includes a driving gear and a pressing handle extending tangentially along the driving gear, and the transmission slider includes a driven rack adapted to engage with the driving gear.

[0024] Preferably, in the same side plate, the unlocking operation unit is connected to the anti-rotation pin via a linkage assembly. The linkage assembly includes a first link and a second link. One end of the first link abuts against the side plate, and the other end of the first link is pivotally connected to the second link. The unlocking operation unit applies force to the pivot joint of the first link and the second link to drive the free end of the second link into the anti-rotation groove and push open the anti-rotation pin.

[0025] Preferably, the state locking unit includes a locking spring, the transmission body includes a second spring groove arranged perpendicular to its extension direction, the second spring groove includes an open end and a closed end, the second locking part is extendably disposed in the second spring groove, and the locking spring abuts between the second locking part and the closed end of the second spring groove;

[0026] The first locking part includes an integrally formed first locking groove and a first locking surface, and the second locking part includes an integrally formed first locking buckle and a second locking surface. In the flattened state:

[0027] When the anti-rotation groove is inserted into the anti-rotation groove, the first locking groove engages with the first locking buckle; the second locking part is adapted to follow the movement of the linkage mechanism to separate the first locking groove from the first locking buckle, and the locking spring then drives the second locking part to move to the point where the first stop surface abuts against the second stop surface.

[0028] Preferably, the first locking groove includes a second guide slope, and the first locking buckle includes a second mating slope. The second guide slope and the second mating slope are slidably engaged to guide the first locking groove and the first locking buckle to engage or disengage. The second guide slope and the first stop surface are connected by a transition arc surface. When the second locking part abuts against the transition arc surface, the locking anti-rotation pin completely exits the anti-rotation groove, so that the second locking part can smoothly transition to the position abutting against the first stop surface after disengaging from the first locking groove, ensuring the smoothness of the state transition.

[0029] Preferably, the motherboard includes a first base plate, a first cover plate, and the main cavity formed by the two, and the anti-rotation body is housed in the first cavity.

[0030] Preferably, the transmission body includes a first spring groove adapted to accommodate the reset elastic body, the reset elastic body being a stop-rotation spring, the first spring groove including at least one closed end, and two baffles extending from the first cover plate toward the first bottom plate, the baffles extending into the first spring groove, and the two ends of the stop-rotation spring respectively abutting against the closed end of the first spring groove and the baffles.

[0031] Preferably, the first cover plate includes a guide plate adapted to guide the movement direction of the transmission body, the guide plate being clamped on both sides of the transmission body, and the guide plate being arranged perpendicular to the extension direction of the pivot axis α.

[0032] Preferably, the first cover plate includes a second limiting plate adapted to restrict the transmission body from detaching. The second limiting plate has a movable groove for the anti-rotation pin to extend and retract. In the unfolded state, the movable groove is aligned with the open end of the anti-rotation groove so that the anti-rotation pin can be accurately inserted.

[0033] Preferably, the side plate includes two pivot portions, and the first cover plate includes a pivot bracket adapted to support the pivot portions.

[0034] Preferably, the side panel is provided with a first stop groove at one end adjacent to the main board, and the first cover plate includes a first limiting plate. The first limiting plate is inserted into the first stop groove to indicate that the side panel is flipped upward into place.

[0035] Preferably, the anti-rotation pin includes a first guide slope disposed on its lower surface, and a reset guide slope is disposed on the end of the side plate facing the main board. During the upward flipping of the side plate, the first guide slope and the reset guide slope slide to guide the anti-rotation pin to align with the anti-rotation groove.

[0036] The beneficial effects of this utility model are:

[0037] 1. A linkage mechanism enables the synchronous reverse movement of the two opposing anti-rotation pins, ensuring consistency in the unlocking and locking of both side panels and improving operational stability and reliability. An additional state locking unit is added, which, after unlocking, temporarily abuts against the first and second locking parts to ensure the anti-rotation pins remain temporarily disengaged. No continuous force is required on the unlocking operation unit; a single operation completes the transition from flattened to folded state. After folding, the pins automatically reset and lock, simplifying the operation process.

[0038] Third, the first locking group works in conjunction with the unfolded state to automatically lock, preventing the side panels from folding downwards and ensuring the stability of the tray structure during cleaning. The second locking group takes effect after unlocking, keeping the anti-rotation body in the second state, facilitating the switching of the tray from the unfolded state to the folded state, and preventing the locking mechanism from resetting and interfering with the operation during the switching process.

[0039] IV. The unlocking mechanism uses a transmission structure such as a slider, linkage assembly, or gear rack to drive the anti-rotation pins on both sides to exit the anti-rotation groove simultaneously. The operation is effortless and responsive, and both sides can be unlocked with a single press. The symmetrical transmission design (such as meshing gears and transmission linkages) ensures that the transmission units on both sides move in unison, avoiding jamming or failure caused by uneven force, and improving the smoothness of state switching.

[0065] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0066] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0067] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0068] Example 1

[0069] like Figure 1-8 The flat mop described herein differs from Embodiment 1 in that it includes a mop plate 1 and a mop handle 2. The mop plate 1 includes a main plate 11 adapted to pivotally connect to the mop handle 2 and side plates 12 pivotally connected to both sides of the main plate 11. The main plate 11 includes a first base plate 112, a first cover plate 113, and a main cavity 111 formed by the two. The mop plate 1 has a flattened state and a folded state, wherein: in the flattened state, the two side plates 12 remain flat relative to the main plate 11; in the folded state, the side plates 12 are folded downwards, and the side plates 12 are folded to be perpendicular to the main plate 11. The mop plate 1 includes a medium-long axis l arranged along its length direction and a medium-short axis h arranged along its width direction, and the side plates 12 rotate about the pivot axis α.

[0070] In this embodiment, the side plate 12 includes an anti-rotation groove 31, and the anti-rotation groove 31 has an open end facing the main board 11. The main board 11 is provided with a bidirectional locking module 32 and an unlocking operation part 33 adapted to receive external operating force. The bidirectional locking module 32 includes two anti-rotation pins 34 arranged opposite to each other, a linkage mechanism, and a reset elastic body 38. The two anti-rotation pins 34 are adapted to be inserted into the corresponding anti-rotation grooves 31 respectively to restrict the folding of the side plate 12, thereby locking the slide plate 1 in a flattened state. The reset elastic body 38 is adapted to drive the two anti-rotation pins 34 to enter the anti-rotation grooves 31 synchronously through the linkage mechanism to relock. The pivot axis α is arranged parallel to the middle short axis h, and the anti-rotation pins 34 are arranged perpendicular to the pivot axis α, that is, parallel to the middle long axis l. The anti-rotation pin 34 includes a first guide slope 341 disposed on its lower surface, and the side plate 12 is provided with a reset guide slope 121. During the upward flipping of the side plate 12, the first guide slope 341 and the reset guide slope 121 slide to guide the anti-rotation pin 34 to align with the anti-rotation groove 31.

[0071] In this embodiment, the linkage mechanism includes two transmission units 36, which are centrally symmetrical about the center of the main board 11. The side plate 12 is provided with an unlocking operation part 33, which is adapted to transmit external operating force to its corresponding transmission unit 36 ​​through a stop pin 34. The two transmission units 36 are connected by a transmission mechanism, providing multiple operating methods. Users can select the unlocking operation part on either side plate to unlock according to their actual needs, improving usability. The transmission unit 36 ​​includes a transmission body 35, a first transmission arm 361 and a second transmission arm 371 extending outward from one end of the transmission body 35, a first driven arm 362 connected to the first transmission arm 361, and a second driven arm 372 connected to the second transmission arm 371.

[0072] In this embodiment, the first driven arm 362 includes a first rack 363, and the second driven arm 372 includes a second rack 373. The first rack 363 and the second rack 373 mesh with the same transmission gear 391. The transmission gear 391 is pivotally connected to the main board 11 to ensure that the anti-rotation pins 34 on both sides move synchronously and to prevent the transmission body 35 from shifting or jamming due to force on one side.

[0073] In this embodiment, the flat mop also includes a state locking unit, which includes a first locking part 41, a second locking part 42, and a locking spring 43. The first locking part 41 is disposed on the side plate 12 and moves synchronously with the side plate 12. In the flattened state, the first locking part 41 is in a standby position. The first locking part 41 is integrally formed with a first locking groove 411 and a first stop surface 413. The transmission body 35 includes a second spring groove 352 disposed perpendicular to its extension direction. The second spring groove 352 includes an open end and a closed end. The second locking part 42 is telescopically disposed in the second spring groove 352. The locking spring 43 abuts between the second locking part 42 and the closed end of the second spring groove 352. The second locking part 42 is integrally formed with a first locking buckle 421 and a second stop surface 423. The second locking parts 42 are symmetrically disposed on both sides of the transmission body 35. The first locking groove 411 includes a second guide slope 412, and the first locking buckle 421 includes a second mating slope 422. During the unlocking process of the bidirectional locking module, the second guide slope 412 and the second mating slope 422 slide to guide the first locking groove 411 and the first locking buckle 421 to engage or disengage. The second guide slope 412 and the first stop surface 413 are connected by a transition arc surface 414. When the second locking part 42 abuts against the transition arc surface 414, the anti-rotation pin completely exits the anti-rotation groove 31. When the second locking part 42 separates from the transition arc surface 414, the locking spring 43 is adapted to drive the second stop surface 423 in the second locking part 42 to abut against the first stop surface 413 in the first locking part 41, so as to temporarily restrict the anti-rotation pin 34 to remain disengaged from the anti-rotation groove 31, thereby allowing the side plate 12 to fold.

[0074] In this embodiment, the process of switching the flat mop between the unfolded state and the folded state is as follows:

[0075] In the unfolded state, the tray 1 is placed on a table or the ground so that at least the side plate 12 is supported. Generally, the main plate 11 and the side plate 12 will be supported simultaneously. In one side plate 12, the unlocking operation unit 33 drives the anti-rotation pin 34 in the same side plate 12 to exit the anti-rotation groove 31 through the transmission slider 51. At the same time, the anti-rotation pin 34 drives another anti-rotation pin 34 in the other side plate 12 to exit the anti-rotation groove 31 through the transmission unit. If the other side plate 12 is also provided with an unlocking operation unit 33, then the anti-rotation pin 34 is separated from the transmission slider 51 or the linkage assembly 52, and the unlocking operation unit 33 remains in the state before being pressed. As the first transmission unit 354 and the second transmission unit 355 move towards the center in sync, the locking spring 43 is adapted to drive the second locking part 42 to reset in the direction of the short axis h. The first stop surface 413 abuts against the second stop surface 423 to restrict the anti-rotation body 32 to remain in the second state.

[0076] Holding the mop handle 2 and lifting the mop plate 1, the two side plates 12 lose support and flip downwards, changing the mop plate 1 from an unfolded state to a folded state. The side plates 12 drive the first locking part 41 to flip, disengaging the transmission slider 51 or the linkage assembly 52 from its anti-rotation pin 34, thus releasing the transmission connection. The unlocking operation part 33 remains pressed. The first stop surface 413 separates from the second stop surface 423, and the reset elastic body 38 is adapted to drive the linkage structure to reset, and the anti-rotation pin 34 resets accordingly.

[0077] In the folded state, pressing the main board 11 with the handheld mop handle 2 causes the side panels 12 to flip upwards relative to the main board 11. During the upward flipping of the two side panels 12, the first guide slope 341 and the reset guide slope 121 slide to guide the anti-rotation pin 34 to align with the anti-rotation groove 31. At the same time as the two are aligned, the second locking part 42 abuts against the transition arc surface 414, and the second locking group is still not effective. After alignment, the reset elastic body 38 is adapted to drive the anti-rotation pin 34 to insert into the anti-rotation groove 31 through the transmission unit. One of the anti-rotation pins 34 drives the unlocking operation part 33 to reset through the transmission slider 51. The first locking buckle 421 follows the linkage mechanism and locks into the first locking groove 411, and the mop 1 changes from the unfolded state to the folded state and achieves automatic locking.

[0078] Example 2

[0079] like Figure 21-24The flat mop described herein differs from Embodiment 1 in that the linkage mechanism includes a first transmission unit 354 and a second transmission unit 355 arranged opposite to each other. The first transmission unit 354 includes a transmission body 35, a first transmission arm 361 and a first driven arm 362 connected in sequence. The second transmission unit 355 includes a transmission body 35, a second transmission arm 371 and a second driven arm 372 connected in sequence. An anti-rotation pin 34 is connected to the transmission body 35. The unlocking operation unit 33 includes a first driving inclined surface 331 and a second driving inclined surface 332 symmetrically arranged. The first driven arm 362 includes a first driven inclined surface 363, and the second driven arm 372 includes a second driven inclined surface 373. The first driven inclined surface 363 abuts against the second driving inclined surface 332, and the second driven inclined surface 373 abuts against the second driving inclined surface 332 at the same time. The unlocking operation unit 33 is adapted to simultaneously drive the first transmission unit 354 and the second transmission unit 355 to move synchronously in opposite directions in a direction parallel to the mid-length axis l so as to drive the two anti-rotation pins 34 to exit the anti-rotation groove 31 synchronously and unlock.

[0080] In this embodiment, the unlocking operation unit 33 includes a first driving inclined surface 331 and a second driving inclined surface 332 symmetrically arranged. The first driven arm 362 includes a first driven inclined surface 363, and the second driven arm 372 includes a second driven inclined surface 373. The first driven inclined surface 363 abuts against the second driving inclined surface 332, and the second driven inclined surface 373 abuts against the second driving inclined surface 332 simultaneously. The unlocking operation unit 33 is adapted to simultaneously drive the first transmission unit 36 ​​and the second transmission unit 37 to move synchronously towards the center along a direction parallel to the mid-length axis l. The transmission body 35 includes a first spring groove 351 adapted to accommodate the reset elastic body 38. The first spring groove 351 includes at least one closed end. Two baffles 114 extend from the first cover plate 113 toward the first bottom plate 112. The baffles 114 extend into the first spring groove 351. The two ends of the reset elastic body 38 abut against the closed end of the first spring groove 351 and the baffles 114, respectively.

[0081] In this embodiment, the process of switching the flat mop between the unfolded state and the folded state is as follows:

[0082] In the unfolded state, the tray 1 is placed on a table or the ground so that at least the side plate 12 is supported. Generally, the main plate 11 and the side plate 12 will be supported simultaneously. The unlocking operation unit 33 drives the first transmission unit 354 and the second transmission unit 355 to move towards the center in a synchronized manner. On the one hand, this drives the second locking part 42 to move inward, and the first locking buckle 421 disengages from the first locking groove 411. On the other hand, it drives the anti-rotation pin 34 to disengage from the anti-rotation groove 31. At the same time, the locking spring 43 is adapted to drive the second locking part 42 to reset along the direction of the middle short axis h. The first stop surface 413 abuts against the second stop surface 423 to restrict the anti-rotation body 32 to maintain the second state.

[0083] When the mop handle 2 is held and the mop plate 1 is lifted, the two side plates 12 lose their support and flip downwards, the mop plate 1 changes from an unfolded state to a folded state, the side plates 12 drive the first locking part 41 to flip, the first stop surface 413 separates from the second stop surface 423, the reset elastic body 38 is adapted to drive the transmission unit to reset, and the anti-rotation pin 34 and the unlocking operation part 33 reset accordingly.

[0084] In the folded state, the handheld mop handle 2 presses down on the main board 11, causing the side plate 12 to flip upward relative to the main board 11.
