Description

Technical Field

[0001] This utility model relates to the field of mop technology, specifically a rotating connector and its squeegee mop. Background Technology

[0002] A squeegee mop is a tool designed for cleaning floors, especially suitable for wet floors such as tiles, marble, or wooden floors where water stains or minor stains can be removed. The main function of a squeegee mop is to swipe water; its special material and shape allow it to quickly remove moisture from the floor, keeping it dry, preventing slips and mold growth. Using a squeegee mop easily removes dust, hair, small particles, and water stains, making the floor look cleaner. Squeegee mops are suitable for various floor materials, including tiles, marble, and wooden floors, and can be used in kitchens, bathrooms, living rooms, and other places. In addition to floors, they can also be used for cleaning walls and windows. Compared to traditional mops, squeegee mops are generally lighter and easier to use, completing cleaning tasks faster.

[0003] While squeegee mops are effective at cleaning minor stains and watermarks, current models are not very adaptable. The angle between the squeegee and handle is fixed during cleaning, but for some areas, a slight tilt or even parallel angle between the squeegee and handle is necessary. Therefore, they may not be effective at cleaning stubborn stains. Using a squeegee mop requires some skill to ensure full contact with the floor and effective water removal. Clearly, current squeegee mops are no longer sufficient to meet users' cleaning needs. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a rotating connector and its squeegee mop.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a rotary connector, including a scraper fixing member and a rod fixing member, wherein the scraper fixing member and the rod fixing member are rotatably connected by a hinge structure, and a rotatable or slidable sleeve structure is fitted on the hinge structure, and a limit opening is provided on one or both sides of the lower end of the sleeve structure, and the sleeve structure is limited and fixed by the limit structure.

[0006] Furthermore, the sleeve structure is rotatably configured, and the limiting structure consists of multiple mutually attracting magnet blocks. Two of the magnet blocks are fixed on the front and rear sides of the bottom of the hinge structure, and the other two are fixed on the left and right sides of the bottom of the hinge structure, or fixed in the magnet fixing seats on both sides of the scraper fixing component. The magnet blocks on the front and rear sides of the lower end of the sleeve structure attract one of the pairs of magnet blocks of the hinge structure.

[0007] The upper end of the sleeve structure is provided with one or more evenly arranged limiting grooves, and the rod fixing part is provided with a limiting structure for insertion into the limiting groove on the outside or inside.

[0008] Furthermore, the sleeve structure is rotatably configured, and the limiting structure is a positioning post that penetrates the rod body fixing component. The outer end of the positioning post is an outwardly protruding arc surface structure, and the inner end is fixedly connected to the elastic end of the spring piece fixed in the rod body fixing component. The radial arc surface of the positioning post contacts the limiting groove.

[0009] Furthermore, the sleeve structure is rotatably configured, and the limiting structure is a limiting ring fixedly sleeved on the rod body fixing member. The bottom end face of the limiting ring is provided with a strip-shaped elastic structure, and the bottom of the outer end of the elastic structure is provided with a limiting protrusion for engaging in the limiting groove.

[0010] Furthermore, the sleeve structure adopts a sliding mechanism instead of a rotating mechanism. When the sleeve structure moves to the bottom, the radial arc surface of the positioning post contacts the limiting groove. The lower end of the sleeve structure is engaged with the scraper fixing component through the limiting openings on both sides. The bottom of the sleeve structure also has a fixing hole corresponding to the positioning post. When the sleeve structure moves to the top, the positioning post is just engaged in the fixing hole, and at this time, the limiting opening is completely separated from the scraper fixing component.

[0011] Furthermore, the hinge structure includes a top clamping plate and an intermediate connecting plate located between the clamping plates, with a pivot penetrating through the clamping plates and the intermediate connecting plate, allowing the clamping plates and the intermediate connecting plate to rotate around the pivot.

[0012] Furthermore, the bottom of the scraper fixing component is provided with a long strip-shaped fixing groove.

[0013] Furthermore, the upper end of the rod fixing component is provided with an internal thread structure or a locking sleeve structure to fix the mop rod.

[0014] Furthermore, the outer side of each clamping plate and both sides of the middle connecting plate are respectively outwardly protruding arc-shaped structures, each arc-shaped structure forming a structure with a circular horizontal cross section, and the scraper fixing component fixedly connected to the hinge structure is provided with a circular baffle covering the lower end of the sleeve structure.

[0015] A squeegee mop includes a rod and the aforementioned rotating connector. The rod is fixedly connected to a rod fixing member via a threaded structure, and a squeegee fixing member has a squeegee structure fixed to it.

[0016] Furthermore, the rod is composed of multiple sections, which are fixedly connected by a threaded structure.

[0017] Furthermore, a hanging ring structure is provided at the top of the rod.

[0018] This utility model has two different states. State 1 is the active state in which the hinge structure can rotate freely, and State 2 is the limited state in which the hinge structure cannot rotate. In the active state, when the hinge structure, i.e., the middle connecting plate of the hinge structure, and the limiting opening are on the same plane, that is, when the middle connecting plate can rotate through the limiting opening, the mop handle and the scraper fixing part of the fixed scraper structure can rotate freely, which is convenient for the user to swing the scraper left and right to scrape water and clean. In addition, when it is necessary to lock the hinge structure, i.e., in the limited state, it is only necessary to rotate the sleeve structure so that the middle connecting plate of the hinge structure and the limiting opening are not on the same plane, thereby forming a blocking structure on both sides of the bottom of the sleeve structure to block the hinge structure, so that the hinge structure cannot rotate, which is convenient for the user to push the scraper back and forth to scrape water.

[0019] The sleeve structure can also use a sliding setting instead of a rotating setting. When the sleeve structure moves to the bottom, the radial arc surface of the positioning post contacts the limiting groove. The lower end of the sleeve structure is locked onto the scraper fixing component through the limiting openings on both sides, thus preventing the rod fixing component from rotating around the hinge structure. The bottom of the sleeve structure also has a fixing hole corresponding to the positioning post. When the sleeve structure moves to the top, the positioning post is just locked into the fixing hole, and at this time the limiting opening is completely separated from the scraper fixing component. At this time, the rod fixing component can rotate around the hinge structure. Alternatively, multiple pairs of magnets can attract each other to form a limiting structure for the sleeve structure, so that the sleeve structure is in different states when attracted and fixed to different magnets. This switching between different states, and the convenient and quick switching between the two states, better meets the user's cleaning needs. Attached Figure Description

[0030] The following is a detailed description of this embodiment with reference to the accompanying drawings:

[0031] Example 1

[0032] like Figure 1 , 3 As shown in Figure 4, a rotating connector includes a scraper fixing member 1 and a rod fixing member 2. The scraper fixing member 1 and the rod fixing member 2 are rotatably connected by a hinge structure 3. A rotatable sleeve structure 4 is fitted onto the hinge structure 3. A limiting opening 5 is provided on one or both sides of the lower end of the sleeve structure 4. A plurality of evenly arranged limiting grooves 6 are provided at the upper end of the sleeve structure 4. A limiting structure for insertion into the limiting grooves 6 is provided on the outside or inside of the rod fixing member 2.

[0033] The hinge structure 3 includes a top clamping plate 12 and an intermediate connecting plate 13 located between the clamping plates 12. The pivot passes through the clamping plates 12 and the intermediate connecting plate 13, allowing the clamping plates 12 and the intermediate connecting plate 13 to rotate around the pivot. The outer side of each clamping plate 12 and the two sides of the intermediate connecting plate 13 are respectively outwardly protruding arc surface structures. Each arc surface structure forms a structure with a circular horizontal cross section. The scraper fixing member 1, which is fixedly connected to the hinge structure 3, is provided with a circular baffle covering the lower end of the sleeve structure 4 to prevent the sleeve structure 4 from sliding downward. At the same time, it facilitates the effective support of the lower end of the sleeve structure 4 when it rotates. The bottom of the scraper fixing member 1 is provided with a long strip-shaped fixing groove 14 for inserting and fixing the scraper structure 16. The upper end of the rod fixing member 2 is provided with an internal thread structure or a locking sleeve structure to fix the mop handle. The locking sleeve is like the mop handle sleeve locking component commonly found on the market.

[0034] The limiting structure is a positioning post 7 that passes through the rod fixing member 2. The outer end of the positioning post 7 is an outwardly protruding arc surface structure, and the inner end is fixedly connected to the elastic end of the spring piece 8 fixed in the rod fixing member 2. The radial arc surface of the positioning post 7 contacts the limiting groove 6. When it is necessary to rotate the sleeve structure 4, the positioning post 7 is pressed inward, and the sleeve structure 4 is rotated to a suitable position, that is, rotated to another limiting groove 6 part. Under the elastic force of the spring piece 8, the positioning post 7 springs back into the limiting groove 6, thereby completing the limiting.

[0035] Example 2

[0036] like Figure 2 , 4 As shown, a rotating connector includes a scraper fixing member 1 and a rod fixing member 2. The scraper fixing member 1 and the rod fixing member 2 are rotatably connected by a hinge structure 3. A rotatable sleeve structure 4 is fitted onto the hinge structure 3. A limiting opening 5 is provided on one or both sides of the lower end of the sleeve structure 4. A plurality of evenly arranged limiting grooves 6 are provided at the upper end of the sleeve structure 4. A limiting structure for insertion into the limiting grooves 6 is provided on the outside or inside of the rod fixing member 2.

[0037] The hinge structure 3 includes a top clamping plate 12 and an intermediate connecting plate 13 located between the clamping plates 12. The pivot passes through the clamping plates 12 and the intermediate connecting plate 13, allowing the clamping plates 12 and the intermediate connecting plate 13 to rotate around the pivot. The outer side of each clamping plate 12 and the two sides of the intermediate connecting plate 13 are respectively outwardly protruding arc surface structures. Each arc surface structure forms a structure with a circular horizontal cross section. The scraper fixing member 1, which is fixedly connected to the hinge structure 3, is provided with a circular baffle covering the lower end of the sleeve structure 4. The bottom of the scraper fixing member 1 is provided with a long strip-shaped fixing groove 14 for inserting and fixing the scraper structure 16. The upper end of the rod fixing member 2 is provided with an internal thread structure or a locking sleeve structure to fix the mop rod.

[0038] The limiting structure is a limiting ring 9 fixedly sleeved on the rod body fixing member 2. The bottom end face of the limiting ring 9 is provided with a strip-shaped elastic structure 10, which is integrally formed with the limiting ring 9 by plastic injection molding or by mechanical metal processing. The bottom of the outer end of the elastic structure 10 is provided with a limiting protrusion 11 for locking into the limiting groove 6. When it is necessary to rotate the sleeve structure 4, the sleeve structure 4 is rotated with force. Under the action of this force, the limiting protrusion 11 is forced to press upward, thereby gradually disengaging from the limiting groove 6, until it is locked into the next limiting groove 6 for limiting as it rotates.

[0039] Example 3

[0040] like Figure 6 As shown, a rotating connector includes a scraper fixing member 1 and a rod fixing member 2. The scraper fixing member 1 and the rod fixing member 2 are rotatably connected by a hinge structure 3. A slidable sleeve structure 4 is fitted onto the hinge structure 3. A limiting opening 5 is provided on one or both sides of the lower end of the sleeve structure 4. A limiting groove 6 is provided at the upper end of the sleeve structure 4. A limiting structure for insertion into the limiting groove 6 is provided on the outside or inside of the rod fixing member 2.

[0041] The hinge structure 3 includes a top clamping plate 12 and an intermediate connecting plate 13 located between the clamping plates 12. The pivot passes through the clamping plates 12 and the intermediate connecting plate 13, allowing the clamping plates 12 and the intermediate connecting plate 13 to rotate around the pivot. The outer side of each clamping plate 12 and the two sides of the intermediate connecting plate 13 are respectively outwardly protruding arc surface structures. Each arc surface structure forms a structure with a circular horizontal cross section. The bottom of the scraper fixing member 1 is provided with a long strip-shaped fixing groove 14 for inserting and fixing the scraper structure 16. The upper end of the rod fixing member 2 is provided with an internal thread structure or a locking sleeve structure for fixing the mop handle.

[0042] The sleeve structure 4 adopts a sliding setting instead of a rotating setting. To prevent the sleeve structure 4 from rotating, the outer wall of the rod fixing member 2 can be provided with a long strip-shaped limiting strip or limiting slide rail arranged along the axial direction, which cooperates with the inner wall slide rail of the sleeve structure 4. The outer end of the positioning post 7 is an outwardly protruding arc surface structure, and the inner end is fixedly connected to the elastic end of the spring piece 8 fixed in the rod fixing member 2. The radial arc surface of the positioning post 7 contacts the limiting groove 6, and when the sleeve structure moves to the bottom, the radial arc surface of the positioning post 7 contacts the limiting groove 6. The lower end of the sleeve structure 4 is stuck on the scraper fixing member 1 through the limiting openings 5 ​​provided on both sides, so that the rod fixing member 2 cannot rotate around the hinge structure 3. The bottom of the sleeve structure 4 is also provided with a fixing hole 18 corresponding to the positioning post 7. When the sleeve structure 4 moves to the top, the positioning post 7 is just stuck in the fixing hole 18, and at this time the limiting opening 5 is completely separated from the scraper fixing member 1. At this time, the rod fixing member 2 can rotate around the hinge structure 3.

[0043] Example 4

[0044] like Figure 7 As shown, a rotating connector includes a scraper fixing member 1 and a rod fixing member 2. The scraper fixing member 1 and the rod fixing member 2 are rotatably connected by a hinge structure 3. A slidable sleeve structure 4 is fitted onto the hinge structure 3. A limit opening 5 is provided on one or both sides of the lower end of the sleeve structure 4. The sleeve structure 4 is limited and fixed by the limit structure.

[0045] The hinge structure 3 includes a top clamping plate 12 and an intermediate connecting plate 13 located between the clamping plates 12. The pivot passes through the clamping plates 12 and the intermediate connecting plate 13, allowing the clamping plates 12 and the intermediate connecting plate 13 to rotate around the pivot. The outer side of each clamping plate 12 and the two sides of the intermediate connecting plate 13 are respectively outwardly protruding arc surface structures. Each arc surface structure forms a structure with a circular horizontal cross section. The bottom of the scraper fixing member 1 is provided with a long strip-shaped fixing groove 14 for inserting and fixing the scraper structure 16. The upper end of the rod fixing member 2 is provided with an internal thread structure or a locking sleeve structure for fixing the mop handle.

[0046] The sleeve structure 4 is rotatably set, and the limiting structure is a plurality of magnet blocks 19 that attract each other. Two of the magnet blocks 19 are fixed on the front and rear sides of the bottom of the hinge structure 3, and the other two are fixed on the left and right sides of the bottom of the hinge structure 3, or fixed in the magnet fixing seats 20 on both sides of the surface of the scraper fixing member 1. The magnet blocks 19 on the front and rear sides of the lower end of the sleeve structure 4 attract each other to one of the pair of magnet blocks 19 of the hinge structure 3.

[0047] Example 5

[0048] like Figure 5 As shown, a squeegee mop includes a rod 15 and the rotating connector described in embodiments 1 and 2. The rod 15 is fixedly connected to the rod fixing member 2 by a threaded structure. The scraper fixing member 1 is fixed with a scraper structure 16, which can be replaced, such as by fixing with bolts and nuts, and scrapers of different lengths can be replaced. The rod 15 is composed of multiple sections, and each section of the rod 15 is fixedly connected by a threaded structure. A hanging ring structure 17 is provided at the top of the rod 15.

[0049] The working principle of this embodiment is as follows: This utility model has two different states. State one is the active state where the hinge structure can rotate freely, and state two is the limited state where the hinge structure cannot rotate. Limit openings 5 ​​are provided on one or both sides of the lower end of the sleeve structure 4. When the hinge structure 3, i.e., the middle connecting plate 13 of the hinge structure 3, and the limit opening 5 are on the same plane, i.e., the middle connecting plate 13 can rotate through the limit opening 5, the mop handle 15 and the scraper fixing member 1 of the fixed scraper structure 16 can rotate freely. Additionally, when it is necessary to lock the hinge structure 3 to prevent it from rotating... When rotating, simply rotate the sleeve structure 4 so that the middle connecting plate 13 of the hinge structure 3 is not on the same plane as the limiting opening 5. This creates a blocking structure on both sides of the bottom of the sleeve structure 4, preventing the hinge structure 3 from rotating. The working principle of embodiment 3 is the same, except that a sliding latch replaces the rotation setting. In embodiment 4, multiple pairs of magnet blocks 19 attract each other to form a limiting structure for the sleeve structure 4. This allows the sleeve structure 4 to be in different states when attracted and fixed to different magnet blocks 19. By switching between different states, the user's cleaning needs can be better met.

[0050] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
