Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a rotating mop disc assembly. Background Technology

[0002] A spin mop is a type of mop designed to improve cleaning efficiency, characterized by its ability to quickly wash and wring water through rotation.

[0003] Spin mops are typically used with a dedicated mop bucket. This combination makes cleaning easier and effectively removes water from the mop head, reducing water residue after mopping.

[0004] Existing spin mops typically consist of a handle and a disc attached to the end of the handle, with the mop head attached to the bottom of the disc. Because the disc is directly connected to the handle, the contact area at the connection point is relatively small, and the connection point is subjected to significant stress during mopping. Over time, this can lead to breakage and failure at the connection point, resulting in poor stability. Utility Model Content

The lower end of the handle is hinged to the upper end of the upper connecting cylinder, and the turntable is fixedly connected to the lower connecting cylinder.

[0010] In the aforementioned rotating mop disc assembly, the upper part of the upper connecting cylinder has a sheet-like connecting piece, which has a long, strip-shaped connecting hole extending through both sides. It also includes a U-shaped hinge portion for connecting with the handle. The connecting piece is embedded in the U-shaped recess of the hinge portion, and the hinge portion and the connecting piece are hinged by a pin, which passes through the aforementioned connecting hole.

[0011] In the aforementioned rotating mop disc assembly, the upper connecting cylinder has a protruding flange in the middle and also includes a cylindrical outer cylinder. The outer cylinder has a hollow interior and an opening at the bottom. The outer cylinder has through-holes on both sides. The connecting piece matches the inner cavity of the outer cylinder, and the through-holes are aligned with the connecting holes. The cover plate is fitted onto the upper connecting cylinder and is pressed tightly between the flange and the lower end of the outer cylinder.

[0012] In the aforementioned rotating mop disc assembly, the outer cylinder has an annular protruding contact portion on its lower outer side, which abuts against the upper part of the cover disc.

[0013] In the aforementioned rotating mop disc assembly, the upper part of the cover disc has a recessed connecting seat that matches the contact portion, which is located at the connecting seat.

[0014] In the aforementioned rotating mop disc assembly, the lower part of the contact portion has an annular recessed sealing cavity, and a sealing ring is provided inside the sealing cavity. The sealing ring is pressed tightly between the contact portion and the connecting seat.

[0015] In the aforementioned rotating mop disc assembly, the upper end of the lower connecting cylinder has a recessed positioning notch one, and the upper connecting cylinder has a recessed positioning notch two. The positioning notch one and the positioning notch two are directly opposite each other, and there is a contact element between them that can reduce the frictional resistance between the upper connecting cylinder and the lower connecting cylinder.

[0016] In the aforementioned rotating mop disc assembly, the contact element is a ball, and the two sides of the ball are respectively embedded between positioning recess one and positioning recess two.

[0017] In the aforementioned rotating mop disc assembly, the contact element is a contact disc, which includes a disc-shaped disc body and a rod-shaped connecting rod. The upper end of the connecting rod is fixed to the lower part of the center of the disc body. The connecting rod matches and is connected to a first positioning recess, and the disc body matches and is connected to a second positioning recess.

The lower end of the rod body one is fitted onto the upper end of the rod body two, and there is a locking element between the rod body one and the rod body two that can lock the two in place.

[0023] Compared with existing technologies, this rotating mop disc assembly has a larger contact area between the upper connecting cylinder and the lower connecting cylinder because the upper connecting cylinder is fitted on the lower connecting cylinder. At the same time, the frictional resistance between the upper and lower connecting cylinders is reduced by the contact components. Therefore, the disc can not only rotate smoothly in actual use, but also ensure the connection stability of the connection after long-term use due to the large contact area at its rotating connection. It has high practical value.

[0024] Meanwhile, the upper connecting cylinder, lower connecting cylinder, and turntable are all located inside the cover, so its structure is relatively compact. Attached Figure Description

[0034] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0035] like Figure 1 As shown in Figure 7, this rotating mop disc assembly includes a handle 1, a cover 2, and a turntable 3, as well as a transmission component 4. The lower part of the turntable 3 is a connecting part for connecting with the mop head. The lower part of the transmission component 4 is axially fixed to the turntable 3, and the turntable 3 can rotate circumferentially relative to the transmission component 4. The handle 1 is in the shape of a long rod, and the lower end of the handle 1 is hinged to the upper part of the transmission component 4. The cover 2 has a cavity inside and an opening at the bottom. The cover 2 is axially fixed between the transmission component 4 and the turntable 3, and the turntable 3 is located in the inner cavity of the cover 2.

[0036] The transmission component 4 includes a cylindrical upper connecting cylinder 4a and a lower connecting cylinder 4b. The lower end of the upper connecting cylinder 4a is axially fixed to the upper end of the lower connecting cylinder 4b, and the upper connecting cylinder 4a can rotate circumferentially relative to the lower connecting cylinder 4b. The lower end of the handle 1 is hinged to the upper end of the upper connecting cylinder 4a, and the turntable 3 is fixedly connected to the lower connecting cylinder 4b.

[0037] In the transmission component 4, the upper connecting cylinder 4a is sleeved on the lower connecting cylinder 4b, and there is sufficient contact area between the two. Therefore, the upper connecting cylinder 4a can rotate smoothly relative to the lower connecting cylinder 4b.

[0038] Since the handle 1 is connected to the upper connecting cylinder 4a and the turntable 3 is connected to the lower connecting cylinder 4b, the turntable 3 can rotate smoothly relative to the handle 1 during the mop cleaning process. The mop head is connected to the turntable 3, which ultimately enables the mop head to rotate smoothly relative to the handle 1.

[0039] The handle 1 is hinged to the upper connecting cylinder 4a. This structure allows the handle 1 to tilt relative to the turntable 3, improving its applicability.

[0040] The upper part of the upper connecting cylinder 4a has a sheet-like connecting piece 4a1. The connecting piece 4a1 has a long strip-shaped connecting hole 4a11 that runs through both sides of it. The lower end of the handle 1 has a U-shaped hinge part 1a. The connecting piece 4a1 is embedded in the U-shaped notch of the hinge part 1a, and the hinge part 1a and the connecting piece 4a1 are hinged by a pin 5. The pin 5 passes through the connecting hole 4a11.

[0041] The pin 5 passes through the connecting piece 4a1 and the lower end of the handle 1. This structure can stably connect the upper connecting cylinder 4a and the handle 1.

[0042] The upper connecting cylinder 4a has a protruding flange 4a2 in the middle and also includes a cylindrical outer cylinder 6. The outer cylinder 6 has a cavity inside and an opening at the bottom. The outer cylinder 6 has through-holes 6a on both sides. The connecting piece 4a1 matches the inner cavity of the outer cylinder 6 and the through-holes 6a and the connecting holes 4a11 are directly opposite each other. The cover plate 2 is fitted on the upper connecting cylinder 4a and is pressed tightly between the flange 4a2 and the lower end of the outer cylinder 6.

[0043] The outer cylinder 6 has two functions:

[0044] Firstly, it avoids the connecting piece 4a1 being directly hinged to the lower end of the handle 1. Since the connecting piece 4a11 and the outer cylinder 6 are both hinged to the lower end of the handle 1, the connection strength and stability are improved.

[0045] Secondly, the cover plate 2 is pressed tightly between the outer cylinder 6 and the upper connecting cylinder 4a, which enables the cover plate 2 to be stably connected.

[0046] The outer cylinder 6 has an annular protruding contact portion 6b on the outer side of its lower end, and the contact portion 6b abuts against the upper part of the cover plate.

[0047] The contact part 6b increases the contact area between the outer cylinder 6 and the cover plate 2, effectively improving the positioning stability of the cover plate 2.

[0048] The upper part of the cover plate 2 has a recessed connecting seat 2a that matches the contact portion 6b, and the contact portion 6b is located at the connecting seat 2a.

[0049] This structure prevents the contact part 6b from protruding from the upper part of the cover plate 2, thus appropriately improving its structural compactness.

[0050] The lower part of the contact portion 6b has an annular recessed sealing cavity 6b1, and the sealing cavity 6b1 has a sealing ring 7, which is pressed tightly between the contact portion 6b and the connecting seat 2a.

[0051] The sealing ring 7 is positioned at the sealing cavity 6b1. Under the action of the sealing ring 7, the upper part of the cover plate 2 can be stably sealed, preventing water from the turntable 3 from entering the upper part of the cover plate 22.

[0052] The lower connecting cylinder 4b has a recessed positioning notch 4b1 at its upper end, and the upper connecting cylinder 4a has a recessed positioning notch 4a3 inside. The positioning notch 4b1 and the positioning notch 4a3 are directly opposite each other, and there is a contact element 8 between them that can reduce the frictional resistance between the upper connecting cylinder 4a and the lower connecting cylinder 4b.

[0053] The contact element 8 is positioned between the first positioning recess 4b1 and the second positioning recess 4a3. Under the action of the contact element 8, the contact area between the lower end of the upper connecting cylinder 4a and the upper end of the lower connecting cylinder 4b is appropriately reduced, ensuring that the upper connecting cylinder 4a can rotate smoothly relative to the lower connecting cylinder 4b.

[0054] Meanwhile, the upper connecting cylinder 4a is sleeved on the outside of the lower connecting cylinder 4b. Relying on the sufficient contact area on the sides of the two, the stability is ultimately improved, effectively increasing the strength of the connection and rotational stability.

[0055] The contact element 8 is a round bead, with its two sides respectively embedded between the positioning recess 4b1 and the positioning recess 4a3.

[0056] The ball bearings ensure that the lower part of the upper connecting cylinder 4a and the upper part of the lower connecting cylinder 4b maintain rolling contact, thereby appropriately reducing the frictional resistance between them.

[0057] Depending on the actual situation, another option may be adopted:

[0058] That is, the contact element 8 is a contact disc, which includes a disc-shaped disc body 8a and a rod-shaped connecting rod 8b. The upper end of the connecting rod 8b is fixed to the lower part of the center of the disc body 8a. The connecting rod 8b matches and is connected to the positioning recess 4b1. The disc body 8a matches and is connected to the positioning recess 4a4.

[0059] Contact plate 8 is a consumable part; it can be replaced individually after prolonged use. The function of contact plate 8 is the same as that of the ball bearing, therefore its specific function will not be elaborated further.

[0060] However, contact discs and balls each have their advantages. Balls have a simple structure and lower cost, while contact discs are slightly more expensive but have better stability.

[0061] Therefore, ball bearings are used when cost is a primary consideration, while contact discs are used when stability is a primary consideration.

[0062] The upper connecting cylinder 4a has a driving gear 9 on its outer side and a driven gear 10 on its inner side. A transmission gear 11 is located between the driving gear 9 and the driven gear 10. The driving gear 9 and the driven gear 10 are arranged on the same axis and the two sides of the transmission gear 11 are respectively meshed on the driving gear 9 and the driven gear 10.

[0063] During the rotation of the upper connecting cylinder 4a, the driven gear 10 rotates along with the transmission gear 11. The aforementioned driving gear 9, driven gear 10, and transmission gear 11 are planetary gear transmissions. The number of transmission gears 11 is several. The arrangement of multiple transmission gears 11 can improve the stability of power transmission.

[0064] The turntable 3 has a cylindrical inner connecting cylinder 3a on its inner side. The inner connecting cylinder 3a has an annular protruding fastening edge 3a1 on its inner side. The upper connecting cylinder 4a has an annular protruding fastening edge 4a4 on its outer side. The fastening edge 3a1 abuts against the upper part of the fastening edge 4a4.

[0065] The engaging edge 3a1 on the inner connecting cylinder 3a and the engaging edge 4a4 on the upper connecting cylinder 4a work together to stably fix the turntable 3 axially.

[0066] This mop includes the aforementioned rotating mop disc assembly, and also includes a rod-shaped handle 1, the lower end of which is fixedly connected to a hinge portion 1a on the rotating mop disc assembly.

[0067] The handle 1 includes a long cylindrical rod 1b and a rod 1c. The lower end of the rod 1b is fitted onto the upper end of the rod 1c, and there is a locking element between the rod 1b and the rod 1c that can lock the two in place.

[0068] The locking component is a commercially available part. Therefore, the specific technical solution of the locking component will not be described in detail in the embodiment. The locking component has two states: locked and unlocked. When the position of rod 1b relative to rod 2c is determined, locking the locking component can ensure that rod 1b and rod 2c are stably connected together.

[0069] When the length of handlebar 1 needs to be adjusted, after the locking mechanism is unlocked, lever 1b can move relative to lever 1c, ultimately changing the overall length of the handlebar. Of course, once the length is determined, the locking mechanism can be locked again.

[0070] Because the upper connecting tube is fitted onto the lower connecting tube, the contact area between the two is relatively large. At the same time, the contact element reduces the frictional resistance between the upper and lower connecting tubes. Therefore, in actual use, the turntable can not only rotate smoothly, but also ensure the connection stability of the connection after long-term use due to the large contact area at its rotating connection. It has high practical value.

[0071] Meanwhile, the upper connecting cylinder, lower connecting cylinder, and turntable are all located inside the cover, so its structure is relatively compact.

[0072] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0073] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
