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 and a mop handle. The mop plate includes a main plate and side plates pivotally connected to both sides of the main plate. The mop plate has an unfolded state and a folded state, wherein: in the unfolded state, the two side plates remain flat relative to the main plate; in the folded state, the side plates fold downwards under the action of gravity, and the main plate is adapted to connect the mop handle.

[0005] The flat mop also includes an anti-rotation mechanism and a locking mechanism, the locking mechanism including a first locking group and a second locking group;

[0006] The anti-rotation mechanism includes an unlock button, an anti-rotation slot, and an anti-rotation body. At least one of the side plates is provided with the unlock button. Each side plate is provided with the anti-rotation slot, and the anti-rotation slot has an open end facing the motherboard. The anti-rotation body is disposed on the motherboard and includes an anti-rotation pin, a transmission unit, and an elastic body. The anti-rotation body has a first rotation state and a second state, wherein:

[0007] The elastic body is adapted to drive the anti-rotation pin into the anti-rotation slot through the transmission unit to restrict the side plate from folding down. The anti-rotation body switches to the first state, and the first locking group takes effect to keep the anti-rotation body in the first state.

[0008] The unlocking button is adapted to push the anti-rotation pin located on the same side plate to completely exit the anti-rotation slot, and at the same time, the anti-rotation pin drives the other anti-rotation pin to completely exit the anti-rotation slot through the transmission unit. The anti-rotation body switches to the second state, and the second locking group is then activated to keep the anti-rotation body in the second state.

[0009] In the second state, the slide can be switched from an unfolded state to a folded state, and the second locking group becomes ineffective.

[0010] Preferably, the first locking assembly includes a first locking groove and a first locking buckle. The first locking groove is disposed on the side plate, and the first locking buckle is retractably disposed on the transmission unit. The retraction direction of the first locking buckle is perpendicular to the movement direction of the transmission unit.

[0011] The second locking assembly includes a first stop surface and a second stop surface. The first stop surface is disposed on the side plate, and the second stop surface is telescopically disposed on the transmission unit. The telescopic direction of the second stop surface is perpendicular to the movement direction of the transmission unit.

[0012] The first locking buckle is fixedly connected to or integrally formed with the second stop surface; or, the first locking buckle and the second stop surface are independently disposed in the transmission unit.

[0013] Preferably, the slide includes a medium-length axis l along its length direction and a medium-short axis h along its width direction. The side plate rotates about a pivot axis α, which is parallel to one of the medium-length axis l and the medium-short axis h. The anti-rotation pin is perpendicular to the pivot axis α. An unlocking button is adapted to simultaneously drive the two transmission units to move synchronously toward the center in a direction perpendicular to the pivot axis α.

[0014] Preferably, in the same side plate, the unlock button is connected to the anti-rotation pin via a transmission slider. The unlock button is adapted to drive the transmission slider into the anti-rotation slot and push open the anti-rotation pin. The unlock button includes a driving ramp, and the transmission slider includes a driven ramp adapted to engage with the driving ramp. Through the ramp transmission principle, the operating force of the unlock button is accurately transmitted to the transmission slider. Alternatively, the unlock button 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. Ramp transmission (driving ramp engaging driven ramp) or gear and rack meshing ensures accurate transmission of operating force, avoids idle travel or slippage, and improves unlocking reliability.

[0015] Preferably, in the same side panel, the unlocking button 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 panel, and the other end of the first link is pivotally connected to the second link. The unlocking button applies force to the pivot joint of the first and second links to drive the free end of the second link into the anti-rotation slot and push open the anti-rotation pin. The linkage assembly (such as the first link and the second link) amplifies the operating force through leverage, making it suitable for scenarios requiring a larger unlocking force.

[0016] Preferably, each of the side panels is provided with an unlock button, allowing the user to select any one of the unlock buttons to unlock the anti-rotation mechanism. Alternatively, only one of the side panels may be provided with an unlock button.

[0017] Preferably, the two transmission units are centrally symmetrical about the center of the motherboard. Each 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:

[0018] 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 to ensure that the anti-rotation pins on both sides move synchronously, preventing the transmission body from shifting or jamming due to force on one side. Alternatively, the second driven arm is pivotally connected to both ends of the same transmission link, which is pivotally connected to the main board.

[0019] 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. This optimizes the transmission structure layout, making the transmission process more stable and smooth, avoiding interference between components, improving transmission efficiency and reliability, and ensuring the accuracy and stability of the slide state switching.

[0020] Preferably, the locking mechanism includes a first locking part, a second locking part, and a locking spring. The first locking part is disposed on the side plate and integrally formed with a first locking groove and a first stop surface, simplifying the structural design and ensuring the positional accuracy of both. The transmission body includes a second spring groove perpendicular to its extension direction, the second spring groove having 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, realizing the automatic reset and extension locking function of the second locking part. The second locking part is integrally formed with a first locking buckle and a second stop surface. After the first locking group is released, the locking spring drives the second locking part to reset, making the second locking group effective, restricting the anti-rotation body to maintain the second state, ensuring the smooth operation and stability of the slide folding operation.

[0021] Preferably, the first locking groove includes a second guide slope, and the first locking latch includes a second mating slope. The second guide slope and the second mating slope slide together to guide the first locking groove and the first locking latch to engage or disengage, which reduces frictional resistance and makes the engagement and disengagement actions smoother and less strenuous. It also improves engagement accuracy, ensuring accurate locking and unlocking of the first locking assembly and enhancing the stability of the slide in different states. 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 pin completely exits the anti-rotation slot, ensuring the continuity and reliability of the slide state switching process.

[0022] Preferably, the second locking part is symmetrically arranged on both sides of the transmission body to make the locking force evenly distributed, ensure the force balance of the transmission body, prevent the wear of parts or failure of action due to uneven force, and improve the stability and service life of the locking mechanism.

[0023] Preferably, the second locking part includes two symmetrically arranged limiting parts, and the transmission body includes two symmetrically arranged limiting grooves on both sides of the second spring groove. The limiting grooves are connected to the second spring groove, and the limiting parts can perform limited reciprocating motion within the limiting grooves to restrict the second locking part from disengaging from the second spring groove.

[0024] Preferably, the motherboard includes a first base plate, a first cover plate, and a main cavity formed by the two. The anti-rotation body is housed in the main cavity to prevent external factors such as dust and water stains from intruding and affecting the performance and service life of the anti-rotation body and the locking structure. At the same time, the internal structure layout of the motherboard is more compact and reasonable.

[0025] Preferably, the transmission body includes a first spring groove adapted to receive the elastomer, 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 elastomer respectively abutting the closed end of the first spring groove and the baffles.

[0026] Preferably, the first cover plate includes a guide plate adapted to guide the movement direction of the transmission body. The guide plate is clamped on both sides of the transmission body and is arranged perpendicular to the extension direction of the pivot axis α. This ensures that the transmission body moves along a predetermined direction during movement, prevents deviation or shaking, improves transmission accuracy and stability, and ensures that the anti-rotation pin is accurately inserted into or withdrawn from the anti-rotation slot.

[0027] Preferably, the first cover plate includes a second limiting plate adapted to restrict the transmission body from disengaging. 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 slot so that the anti-rotation pin can be accurately inserted.

[0028] Preferably, the side plate includes two pivot portions, and the first cover plate includes a pivot bracket adapted to support the pivot portions.

[0029] Preferably, the first locking part is disposed on the inner side of the pivot part.

[0030] 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 upwards into place, providing the user with a clear indication of the position and preventing the side panel from being flipped too much or not in place, ensuring that the slide is accurately in the unfolded state.

[0031] Preferably, the anti-rotation pin includes a first guide slope disposed on its lower surface, and a first mating slope is disposed on the end of the side plate facing the motherboard. During the upward flipping of the side plate, the first guide slope and the first mating slope slide to guide the anti-rotation pin to align with the anti-rotation slot, ensuring that the anti-rotation pin can be smoothly inserted into the anti-rotation slot when the side plate is flipped into place, thereby realizing automatic locking of the slide and improving the efficiency and reliability of slide state switching.

[0032] The beneficial effects of this utility model are:

[0033] 1. The transmission unit is driven by the unlock button to synchronously control the switching of the anti-rotation pin and the locking mechanism. A single press can complete the transition from unfolded to folded state. After folding, it automatically resets and locks, simplifying the operation process.

[0034] Second, 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.

[0035] 3. The unlock button 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 slot simultaneously. The operation is effortless and the response is rapid; a single press is sufficient to unlock both sides. 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] Example 1

[0059] like Figure 1-7A flat mop 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 an unfolded state and a folded state, wherein: in the unfolded 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 a pivot axis α.

[0060] In this embodiment, the flat mop also includes an anti-rotation mechanism and a locking mechanism. The anti-rotation mechanism includes an anti-rotation slot 31 and an anti-rotation body 32. The anti-rotation slot 31 is disposed on the side plate 12 and has an open end facing the main board 11. The anti-rotation body 32 is housed in the main cavity 111 and includes an unlock button 33, an anti-rotation pin 34, two transmission units 36, and an elastic body 38. The unlock button 33 is adapted to extend out of the first cover plate 113 and is disposed directly above the short axis h. The two transmission units 36 are centrally symmetrical about the center of the main board 11. Each 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, 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. The anti-rotation pin is connected to the transmission body 35. The pivot axis α is set parallel to the short axis h, and the anti-rotation pin 34 is set perpendicular to the pivot axis α, that is, parallel to the long axis l. The anti-rotation pin 34 includes a first guide slope 341 set on its lower surface, and a first mating slope 121 is set on the end of the side plate 12 facing the main plate 11. During the upward flipping of the side plate 12, the first guide slope 341 and the first mating slope 121 slide to guide the anti-rotation pin 34 to align with the anti-rotation slot 31.

[0061] 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.

[0062] In this embodiment, the locking mechanism 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 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. The second guide slope 412 and the second mating slope 422 are slidably engaged 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 is completely withdrawn from the anti-rotation slot 31. The first locking groove 411 and the first locking buckle 421 constitute a first locking group, and the first stop surface 413 and the second stop surface 423 constitute a second locking group.

[0063] In this embodiment, the anti-rotation body 32 has a first rotation state and a second state. The elastic body 38 is adapted to drive the anti-rotation pin 34 into the anti-rotation slot 31 through the transmission unit to restrict the side plate 12 from folding downward, ensuring that the tray 1 remains stable in the unfolded state, preventing the tray 1 from accidentally folding during cleaning, and ensuring smooth cleaning operation. When the anti-rotation body 32 switches to the first state, the first locking group is activated to keep the anti-rotation body 32 in the first state. The unlocking button 33 is adapted to drive the anti-rotation pin 34 completely out of the anti-rotation slot 31 through the transmission unit, and the anti-rotation body 32 switches to the second state. When the second locking group is activated, the anti-rotation body 32 is activated to keep the anti-rotation body 32 in the second state. In the second state, the tray 1 can switch from the unfolded state to the folded state, realizing flexible switching of the state of the tray 1, which is convenient to operate, and the second locking group is disengaged.

[0064] In this embodiment, on the same side plate 12, the unlocking button 33 is connected to the anti-rotation pin 34 via a transmission slider 51. The unlocking button 33 is adapted to drive the transmission slider 51 into the anti-rotation slot 31 and push open the anti-rotation pin 34. The unlocking button 33 includes a driving inclined surface 331, and the transmission slider 51 includes a driven inclined surface 511 adapted to cooperate with the driving inclined surface 331. Through the inclined surface transmission principle, the operating force of the unlocking button 33 is accurately transmitted to the transmission slider 51. Each side plate 12 is provided with an unlocking button 33, and the user can select any unlocking button 33 to unlock the anti-rotation mechanism.

[0065] In other embodiments, such as Figure 8 As shown, only one side panel 12 has an unlock button 33.

[0066] The process of switching between unfolded and folded states for a flat mop is as follows:

[0067] 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 unlock button 33 drives the anti-rotation pin 34 in the same side plate 12 to exit the anti-rotation slot 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 slot 31 through the transmission unit. If the other side plate 12 is also provided with an unlock button 33, then the anti-rotation pin 34 is separated from the transmission slider 51 or the linkage assembly 52, and the unlock button 33 remains in the state before being pressed. The first locking group is released as the two transmission units 36 move towards the center synchronously. Then, the locking spring 43 is adapted to drive the second locking part 42 to reset in the direction of the short axis h. The second locking group is activated, that is, 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.

[0068] 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 connecting rod assembly 52 from its anti-rotation pin 34, thus releasing the transmission connection. The unlocking button 33 remains pressed. The first stop surface 413 separates from the second stop surface 423, the second locking group fails, and the elastic body 38 is adapted to drive the transmission unit to reset, and the anti-rotation pin resets accordingly.

[0069] 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 guide slope and the mating slope slide to guide the anti-rotation pin 34 to align with the anti-rotation slot 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 active. After alignment, the elastic body 38 is adapted to drive the anti-rotation pin 34 to insert into the anti-rotation slot 31 through the transmission unit. One of the anti-rotation pins 34 drives the unlocking button 33 to reset through the transmission slider 51. The first locking group is activated with the movement of the transmission unit, the anti-rotation body 32 is converted and maintained in the first state, and the mop 1 is converted from the unfolded state to the folded state and achieves automatic locking.

[0070] In this embodiment, the first driven arm 362 is arranged in a direction perpendicular to the pivot axis α, and the second driven arm 372 is arranged parallel to the first driven arm 362. The first transmission arm 361 and the second transmission arm 371 are adapted to guide the first driven arm 362 and the second driven arm 372 to be misaligned along the extension direction of the pivot axis α. This optimizes the transmission structure layout, making the transmission process more stable and smooth, and avoiding interference between components.

[0071] In this embodiment, the side plate 12 includes two pivot portions 122, and the first cover plate 113 includes a pivot bracket 115 adapted to support the pivot portions 122. A first locking portion 41 is disposed on the inner side of the pivot portion 122. A first stop groove 123 is provided at one end of the side plate 12 adjacent to the main plate 11, and the first cover plate 113 includes a first limiting plate 116. The first limiting plate 116 is inserted into the first stop groove 123 to indicate that the side plate 12 is flipped upward into place.

[0072] In this embodiment, the first cover plate 113 includes a guide plate 118 adapted to guide the movement direction of the transmission body 35. The guide plate 118 is clamped on both sides of the transmission body 35 and is arranged perpendicular to the extension direction of the pivot axis α to ensure that the transmission body 35 moves along a predetermined direction during movement, preventing deviation or shaking. The first cover plate 113 includes a second limiting plate 117 adapted to restrict the transmission body 35 from disengaging. The second limiting plate 117 has a movable groove 1171 for the anti-rotation pin 34 to extend and retract. In the unfolded state, the movable groove 1171 is aligned with the open end of the anti-rotation slot 31 so that the anti-rotation pin 34 can be accurately inserted. The transmission body 35 includes a first spring groove 351 adapted to accommodate an 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 elastic body 38 abut against the closed end of the first spring groove 351 and the baffles 114, respectively.

[0073] In this embodiment, the second locking part 42 includes two symmetrically arranged limiting parts 424, and the transmission body 35 includes two symmetrically arranged limiting grooves 353 on both sides of the second spring groove 352. The limiting grooves 353 are connected to the second spring groove 352, and the limiting parts 424 can perform limited reciprocating motion within the limiting grooves 353 to restrict the second locking part 42 from disengaging from the second spring groove 352.

[0074] Example 2

[0075] like Figure 9-11 The flat mop described herein differs from Embodiment 1 in that the second driven arm 372 is pivotally connected to both ends of the same transmission link 392, and the transmission link 392 is pivotally connected to the main board 11.

[0076] In other embodiments, such as Figure 12 As shown, only one side panel 12 has an unlock button 33.

[0077] Example 3

[0078] like Figure 13-15 The aforementioned flat mop, compared to Embodiment 1, differs in that, in the same side plate 12, the unlocking button 33 is connected to the anti-rotation pin 34 via a transmission slider 51. The unlocking button 33 is adapted to drive the transmission slider 51 into the anti-rotation slot 31 and push open the anti-rotation pin 34. The unlocking button 33 includes a drive gear 332 and a pressing handle 333 extending tangentially along the drive gear 332. The transmission slider 51 includes a driven rack 512 adapted to engage with the drive gear 332. The gear and rack meshing ensures accurate transmission of operating force, avoids idle travel or slippage, and improves unlocking reliability.

[0079] In other embodiments, such as Figure 16-17 As shown, only one side panel 12 has an unlock button 33.

[0080] Example 4

[0081] like Figure 18-19 The aforementioned flat mop, compared to Embodiment 1, differs in that, in the same side plate 12, the unlocking button 33 is connected to the anti-rotation pin 34 via a linkage assembly 52. ​​A linkage abutment post 53 is provided within the side plate 12, aligned with the anti-rotation slot 31. The linkage assembly 52 includes a first linkage 521 and a second linkage 522. One end of the first linkage 521 abuts against the linkage abutment post 53, and the other end of the first linkage 521 is pivotally connected to the second linkage 522. The unlocking button 33 applies force to the pivot point of the first linkage 521 and the second linkage 522 to drive the free end of the second linkage 522 into the anti-rotation slot 31 and push open the anti-rotation pin 34. The linkage assembly 52 (such as the first linkage 521 and the second linkage 522) amplifies the operating force through leverage, making it suitable for scenarios requiring greater unlocking force.
