Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to a segmented rod and a cleaning tool. Background Technology

[0002] Existing cleaning tools, such as mops, brooms, and squeegees, often feature long cleaning handles for ease of use, resulting in significant space requirements during transport and increased shipping and packaging costs. Therefore, to facilitate transport and reduce packaging volume, those skilled in the art have designed cleaning handles as multi-segment units, with the segments screwed together. These segments are then disassembled and reassembled during packaging and transport, reducing space usage and packaging material consumption. However, because the segments are completely separate, assembly requires screwing them together, making the process complex and cumbersome, and resulting in a poor user experience. Utility Model Content

[0003] In view of this, the present invention provides a segmented rod and a cleaning tool to solve the problem that the assembly relationship of segmented rods in the prior art is complicated and cumbersome, resulting in a poor user experience.

[0004] In a first aspect, this utility model provides a segmented rod, including a first rod and a second rod disposed at one end of the first rod, and a connecting device for connecting the first rod and the second rod, the connecting device including:

[0005] The connecting cable is movably disposed within the inner cavities of the first and second rods;

[0006] The drive structure is positioned at the other end of the first rod. One end of the connecting cable is connected to the drive structure, and the other end is connected to the second rod. The drive structure is used to tighten the connecting cable to achieve the connection between the first rod and the second rod.

[0007] Beneficial effects: The drive structure is positioned at the other end of the first rod. One end of the connecting cable is connected to the drive structure, and the other end is connected to the second rod. By controlling the action of the drive structure to tighten the connecting cable and shorten its length, the first and second rods can be connected and fixed together. By using the above method to connect the separate first and second rods, the assembly relationship is not only simpler and the two rods can be quickly assembled and connected, resulting in a better user experience, but also the two rods are not easy to detach after connection, and the stability is high. Furthermore, using the connecting cable as the connecting part of the first and second rods, due to the flexibility of the connecting cable, the two rods can be folded, saving space and facilitating packaging and transportation. This effectively solves the problems of complex and cumbersome assembly relationships and poor user experience in the existing technology of segmented rod assembly.

[0008] In one alternative embodiment, the connecting cable passes through the inner cavity of the first rod and the second rod;

[0009] The connecting cable has a first end and a second end. The first end of the connecting cable is limited to the end of the second rod away from the first rod, and the second end of the connecting cable is connected to the drive structure for transmission.

[0010] The drive structure is used to pull the first end of the connecting cable toward the second end, so as to tension the connecting cable and realize the connection between the first rod and the second rod.

[0011] Beneficial effects: By controlling the action of the drive structure, the first end of the transmission cable can be pulled closer to the second end, so that the connecting cable is tensioned, thereby tightening the first rod and the second rod to achieve the connection and fixation of the two. The assembly method is simple and easy to operate.

[0012] In one alternative implementation, the drive structure rotates to pull the second end of the connecting cable, causing the connecting cable to wrap around the drive structure.

[0013] Beneficial effects: Users can rotate the drive structure to make the connecting cable wrap around the drive structure, shortening the length of the connecting cable, thereby tightening the second rod and the first rod together. This fixes the segmented first and second rods together, preventing them from separating. The connection and fixation of the first and second rods is achieved by using a rotating drive structure, which is simple and convenient to operate, bringing great convenience to users and providing a good user experience.

[0014] In one alternative implementation, the driving structure includes:

[0015] The second end of the connecting cable is connected to the winding roller, which is driven to rotate to wind and tighten the connecting cable.

[0016] Beneficial effects: The drive structure adopts a winding roller design, which facilitates the winding of the connecting cable. When the drive structure is activated, the winding roller can rotate accordingly, thereby winding and tightening the connecting cable, shortening the length of the connecting cable, and thus enabling the connection and fixation of the first rod and the second rod.

[0017] In one alternative implementation, the drive structure further includes:

[0018] The transmission component is connected to the winding roller and is used to drive the winding roller to rotate.

[0019] Beneficial effects: By driving the winding roller to rotate through the transmission components, it is possible to achieve easy and labor-saving results, and make the winding roller rotate more smoothly and reliably.

[0020] In one alternative embodiment, the transmission component includes:

[0021] The first transmission component is rotatably disposed at one end of the first rod;

[0022] The second transmission component is fixedly connected to the winding roller, and the first transmission component is connected to the second transmission component in a transmission connection.

[0023] The first transmission component rotates, which in turn drives the second transmission component to rotate, thereby driving the winding roller to rotate.

[0024] Beneficial effects: The transmission component adopts a structure in which the first rotating part and the second transmission part are connected in a transmission cooperation. When the first transmission part is driven, it can drive the second transmission part to rotate, thereby driving the winding roller fixedly connected to it to rotate, and thus realizing the winding and tightening of the connecting cable.

[0025] In one alternative embodiment, the rotation shaft of the second transmission member is coaxial with the central shaft of the winding roller, and the rotation shaft of the first transmission member is coaxial with the central shaft of the first rod.

[0026] Beneficial effects: By setting the second transmission component and the winding roller to be coaxial, the second transmission component can drive the winding roller to rotate synchronously when it rotates, thereby effectively ensuring the stability and consistency of the winding roller's movement. In addition, by setting the rotation axis of the first transmission component to be coaxial with the central axis of the first rod, the problem of large space occupation and non-compact structure caused by the first transmission component rotating at an angle relative to the first rod can be avoided.

[0027] In one alternative embodiment, the first transmission member portion is inserted into the first rod body and has an insertion end;

[0028] The first transmission member has an input gear at its insertion end, and the second transmission member includes an output gear that meshes with the input gear.

[0029] Beneficial effects: The first transmission component has an input gear at one end that extends into the first rod body, and the second transmission component includes an output gear that meshes with the input gear. By adopting the design of meshing transmission between the input gear and the output gear, the first and second transmission components not only have a simple structure, but also have smooth and reliable transmission, which can make the second transmission component and the winding roller rotate more smoothly, thereby enabling precise control of the winding length of the connecting cable.

[0030] In one alternative embodiment, the transmission component is a worm gear, and the winding roller is a worm.

[0031] Beneficial effects: The transmission components and the winding roller are driven by a worm gear, resulting in a compact structure, high reliability, and good synchronization and stability, thus improving the rotational accuracy and controllability of the winding roller. By constructing the winding roller as a worm gear, the structure can be further simplified, allowing for multiple uses.

[0032] In one alternative implementation, the tooth surface of the worm gear faces the inner circumference of the first rod;

[0033] The rotation axis of the worm gear is coaxial with the central axis of the first rod, so that the rotation of the worm gear can drive the worm to rotate.

[0034] Beneficial effects: The tooth surface of the worm gear faces the inner circumference of the first rod, and the rotation axis of the worm gear is coaxial with the central axis of the first rod, thus enabling the worm gear to rotate coaxially within the first rod, avoiding the problems of large space occupation and non-compact structure caused by the worm gear rotating at an angle.

[0035] In one alternative implementation, the driving structure includes:

[0036] An operating element is connected to a connecting cable between the operating element and the second rod. The operating element has a locked position close to the second rod and a relaxed position away from the second rod.

[0037] When the operating component moves from the relaxed position to the locked position, it can cause the connecting cable to tighten the first and second rods.

[0038] Beneficial effects: By controlling the operating part to move from the relaxed position to the locking position towards the second rod, the connecting cable can be tightened, thereby tightening the first and second rods to achieve a fixed connection between them. The operation is very convenient and quick.

[0039] In one alternative implementation, the connecting cable is a rope that is fixedly connected to the operating component.

[0040] Beneficial effects: The connecting cable, by adopting the form of a rope, has a simple structure, low cost, and is easy to pull and wind.

[0041] In one alternative implementation, it further includes:

[0042] A locking structure is provided between the first rod and the drive structure to lock the drive structure.

[0043] Beneficial effects: By setting a locking structure between the first rod and the drive structure, the drive structure can be locked, preventing the drive structure from moving arbitrarily and ensuring the stability and reliability of the connection between the first rod and the second rod.

[0044] In one alternative implementation, the drive structure can pull the end of the connecting cable that is connected to the second rod when it rotates;

[0045] The locking structure includes a limiting tooth groove and a ratchet;

[0046] One of the limiting grooves and the ratchet is located on the first rod body, and the other is located on the drive structure. The ratchet cooperates with the limiting groove to restrict the reverse rotation of the drive structure.

[0047] Beneficial effects: By controlling the drive structure to rotate in the preset locking direction, the end of the connecting cable connected to the second rod can be pulled, tightening the first and second rods to achieve a fixed connection between them. The locking structure, through the design of limiting grooves and ratchet teeth, ensures that the drive structure can only rotate in the preset locking direction and will not rotate in the opposite direction, thus preventing the drive structure from rotating in the opposite direction to release the connecting cable and causing the connection between the first and second rods to fail.

[0048] In one alternative implementation, the locking structure includes a latch and a slot;

[0049] One of the latches and the slot is located on the first rod body, and the other is located on the drive structure. When the drive structure rotates to the preset position, the latch and the slot cooperate to lock the drive structure.

[0050] Beneficial effects: When the drive structure rotates along the preset locking direction, it can wind the connecting cable. When the drive structure rotates to the preset position where the length of the connecting cable is sufficient to tighten and fix the first and second rods, the buckle and the slot engage to lock the drive structure to the preset position. This effectively prevents the drive structure from moving arbitrarily and affecting the fixing effect of the first and second rods. Furthermore, the locking structure, by using buckles and slots, has a simple structure, better stability and reliability, and is not easy to come off.

[0051] In one alternative embodiment, a limiting element is provided at the end of the connecting cable that connects to the second rod.

[0052] The second rod body is provided with a limiting engagement part, and the limiting engagement part has a through hole through which the connecting cable can pass. The limiting member abuts and limits the limiting engagement part on the side away from the driving structure.

[0053] Beneficial effects: The limiting component is positioned on the side of the limiting mating part away from the driving structure. One end of the connecting cable is connected to the limiting component, and the other end passes through the limiting mating part and is connected to the driving structure. The connection between the connecting cable and the second rod is achieved in the above manner, making disassembly and assembly more convenient and quick.

[0054] In one alternative embodiment, the limiting member is a limiting block, the width of which is greater than the diameter of the through hole, to prevent the limiting block from passing through the through hole.

[0055] Beneficial effects: The limiting component adopts the form of a limiting block, which has a simple structure, strong load-bearing capacity, and high structural strength. Furthermore, by setting the width of the limiting block to be greater than the diameter of the through hole, it can effectively prevent the limiting block from coming out of the through hole, thereby improving the stability of the fit between the limiting block and the limiting mating part.

[0056] Secondly, this utility model also provides a cleaning tool, comprising:

[0057] In any of the above embodiments, the segmented rod and cleaning head are connected by a connecting device;

[0058] The cleaning head is connected to one end of the second rod, and the first rod is a straight or curved handle located at the other end of the second rod.

[0059] Beneficial effects: The cleaning tool's cleaning handle features a segmented design, with each segment connected by a connecting cable. A drive structure tightens the cable, allowing for easy assembly, high stability, and foldable components, saving space and reducing maintenance and transportation costs. This effectively solves the problems of complex and unstable segmented assembly, and excessive space requirements during transport, inherent in existing cleaning tools. Furthermore, by constructing the first handle as either a straight or curved tail, users can choose the appropriate type of cleaning tool, resulting in a better user experience.

[0081] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0082] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0083] According to an embodiment of the present invention, in one aspect, the present invention provides a segmented rod 10, including a first rod 11 and a second rod 12 disposed at one end of the first rod 11, and a connecting device for connecting the first rod 11 and the second rod 12. The connecting device includes a connecting cable 13 and a driving structure 14. The connecting cable 13 is movably disposed in the inner cavity of the first rod 11 and the second rod 12. The driving structure 14 is limited to the other end of the first rod 11. One end of the connecting cable 13 is connected to the driving structure 14, and the other end is connected to the second rod 12. The driving structure 14 is used to tighten the connecting cable 13 to realize the connection between the first rod 11 and the second rod 12.

[0084] In the above embodiment, the drive structure 14 is limited to the other end of the first rod 11. One end of the connecting cable 13 is connected to the drive structure 14, and the other end is connected to the second rod 12. By controlling the action of the drive structure 14 to tighten the connecting cable 13 to shorten its length, the first rod 11 and the second rod 12 can be connected and fixed together. By adopting the above method to connect the separate first rod 11 and the second rod 12, the assembly relationship is not only simpler, but the assembly and docking of the two rods can be completed quickly, resulting in a better user experience. Moreover, the two rods are not easy to detach after connection, and the stability is high. Furthermore, using the connecting cable 13 as the connecting part of the first rod 11 and the second rod 12, the two rods can be folded due to the flexibility of the connecting cable 13, which saves space and facilitates packaging and transportation. This effectively solves the problem of complex and cumbersome assembly relationship of the segmented rod 10 in the prior art, resulting in a poor user experience.

[0085] Specifically, both the first rod 11 and the second rod 12 are hollow rod-shaped structures. The driving structure 14 is limited to the end of the first rod 11 away from the second rod 12. The connecting cable 13 passes through the first rod 11 and connects to the second rod 12. When the driving structure 14 is driven, it can tighten the connecting cable 13 to realize the connection between the first rod 11 and the second rod 12. The tightening of the connecting cable 13 includes, but is not limited to, making the connecting cable 13 wrap around the driving structure 14, or making the connecting cable 13 switch from a relaxed state to a tense state.

[0086] Furthermore, the connecting cable 13 is a flexible component. The specific structural form of the connecting cable 13 includes, but is not limited to, steel wire rope, rope, chain, ribbon, cloth strip, etc. By using the flexible connecting cable 13 as the connecting structure, this application can easily tighten and fix the first rod 11 and the second rod 12. The structure is simple and the cost is low. Moreover, the connecting cable 13 has a certain degree of flexibility and can be bent at will, which is convenient for storage and folding. It is also convenient for folding the first rod 11 and the second rod 12, saving space.

[0087] In some embodiments, the connecting cable 13 passes through the inner cavity of the first rod 11 and the second rod 12; the connecting cable 13 has a first end and a second end, the first end of the connecting cable 13 is limited to the end of the second rod 12 away from the first rod 11, and the second end of the connecting cable 13 is connected to the driving structure 14; the driving structure 14 is used to pull the first end of the connecting cable 13 towards the second end to make the connecting cable 13 tensioned, thereby realizing the connection between the first rod 11 and the second rod 12.

[0088] In the above embodiment, by controlling the action of the drive structure 14, the first end of the transmission cable can be pulled closer to the second end, so that the connecting cable 13 is tensioned, thereby enabling the first rod 11 and the second rod 12 to be tightened to achieve the connection and fixation of the two. The assembly method is simple and easy to operate.

[0089] In some embodiments, when the drive structure 14 rotates, it pulls the second end of the connecting cable 13, causing the connecting cable 13 to wrap around the drive structure 14.

[0090] In the above embodiment, the user can rotate the drive structure 14 to make the connecting cable 13 wrap around the drive structure 14, shortening the length of the connecting cable 13, thereby tightening the second rod 12 and the first rod 11. This can fix the segmented first rod 11 and the second rod 12 together and prevent them from separating. By using the rotation drive structure 14 to connect and fix the first rod 11 and the second rod 12, the operation is simple and convenient, bringing great convenience to the user and providing a good user experience.

[0091] In some embodiments, the drive structure 14 includes a winding roller 141, the second end of the connecting cable 13 is connected to the winding roller 141, and the winding roller 141 is driven to rotate to wind and tighten the connecting cable 13.

[0092] In the above embodiment, the drive structure 14 adopts the structural design of the winding roller 141, which facilitates the winding of the connecting cable 13. When the drive structure 14 is activated, the winding roller 141 can rotate accordingly, thereby winding and tightening the connecting cable 13, shortening the length of the connecting cable 13, and thus realizing the connection and fixation of the first rod 11 and the second rod 12.

[0093] Specifically, when the first rod 11 and the second rod 12 are connected, they are coaxial. The winding roller 141 is rotatably disposed inside the first rod 11. The winding roller 141 is rod-shaped or cylindrical, and the rotation axis of the winding roller 141 is perpendicular to the central axis of the first rod 11.

[0094] In some embodiments, the drive structure 14 further includes a transmission component 142, which is connected to the winding roller 141 in a transmission manner, and is used to drive the winding roller 141 to rotate.

[0095] In the above embodiment, the winding roller 141 is driven to rotate by the transmission component 142, which can achieve the effect of easy and labor-saving operation and make the winding roller 141 rotate more smoothly and reliably.

[0096] In some embodiments, the transmission component 142 includes a first transmission component and a second transmission component. The first transmission component is rotatably disposed at one end of the first rod 11. The second transmission component is fixedly connected to the winding roller 141, and the first transmission component and the second transmission component are connected in a transmission manner. When the first transmission component is driven to rotate, it drives the second transmission component to rotate, thereby driving the winding roller 141 to rotate.

[0097] In the above embodiment, the transmission component 142 adopts a structure in which the first rotating component and the second transmission component are driven together. When the first transmission component is driven, it can drive the second transmission component to rotate, thereby driving the winding roller 141 fixedly connected to it to rotate, thereby realizing the winding and tightening of the connecting cable 13.

[0098] In some embodiments, the rotation axis of the second transmission member is coaxial with the central axis of the winding roller 141, and the rotation axis of the first transmission member is coaxial with the central axis of the first rod 11.

[0099] In the above embodiments, by setting the second transmission member and the winding roller 141 to be coaxial, the second transmission member can drive the winding roller 141 to rotate synchronously when it rotates, thereby effectively ensuring the stability and consistency of the movement of the winding roller 141. In addition, by setting the rotation axis of the first transmission member to be coaxial with the central axis of the first rod 11, the problem of large space occupation and non-compact structure caused by the first transmission member rotating at an angle relative to the first rod 11 can be avoided.

[0100] In some embodiments, a first transmission member is partially inserted into a first rod 11 and has an insertion end; the insertion end of the first transmission member is provided with an input gear 1421, and the second transmission member includes an output gear 1422 that meshes with the input gear 1421.

[0101] In the above embodiment, an input gear 1421 is provided at one end of the first transmission member that extends into the first rod body 11, and the second transmission member includes an output gear 1422 that meshes with the input gear 1421. By adopting the design of meshing transmission between the input gear 1421 and the output gear 1422, the first and second transmission members not only have a simple structure, but also have smooth and reliable transmission, which can make the second transmission member and the winding roller 141 rotate more smoothly, thereby enabling precise control of the winding length of the connecting cable 13.

[0102] In some preferred embodiments, both the input gear 1421 and the output gear 1422 are bevel gears, which can convert the horizontal rotation of the first transmission member into the vertical rotation of the second transmission member, thereby achieving the purpose of reversing. Furthermore, using bevel gears as the reversing mechanism results in a simple, compact structure that occupies little space.

[0103] Specifically, the input gear 1421 is a driving bevel gear, and the output gear 1422 is a driven bevel gear. The first transmission component also includes a first rotating shaft, which is coaxially arranged with the first rod 11. The first rotating shaft extends from the top of the first rod 11, and the driving bevel gear is fixedly arranged at the lower end of the first rotating shaft. The second transmission component also includes a second rotating shaft, which is rotatably arranged inside the first rod 11 and is perpendicular to the central axis of the first rod 11. The driven bevel gear is fixed at one end of the second rotating shaft, and the driving bevel gear and the driven bevel gear mesh with each other at a 90° angle. This design achieves the meshing of the input gear 1421 and the output gear 1422 while making the overall structure more compact and reducing the occupancy of the diameter of the first rod 11.

[0104] Preferably, in order to further simplify the structure, the second rotating shaft can be used as a winding roller 141, and the second end of the connecting cable 13 is connected to the second rotating shaft. When the output gear 1422 rotates under the drive of the input gear 1421, the second rotating shaft can wind the connecting cable 13 to realize the connection between the first rod 11 and the second rod 12.

[0105] In some embodiments, the transmission component 142 is a worm gear, and the winding roller 141 is a worm.

[0106] In the above embodiments, the transmission component 142 and the winding roller 141 are driven by a worm gear, which results in a compact structure, high reliability, and good synchronization and stability, thus improving the rotational accuracy and controllability of the winding roller 141. By constructing the winding roller 141 as a worm gear, the structure can be further simplified, allowing for multiple uses.

[0107] In some embodiments, the tooth surface of the worm gear faces the inner circumference of the first rod 11; the rotation axis of the worm gear is coaxial with the central axis of the first rod 11, so that the worm gear can drive the worm to rotate when it rotates.

[0108] In the above embodiment, the tooth surface of the worm gear faces the inner circumference of the first rod 11, and the rotation axis of the worm gear is coaxial with the central axis of the first rod 11, thereby enabling the worm gear to rotate coaxially within the first rod 11, avoiding the problem of the worm gear occupying a large space and having an uncompacted structure due to skewed rotation.

[0109] Specifically, the worm wheel and the worm are arranged side by side inside the first rod body 11. The rotation axis of the worm is perpendicular to the central axis of the first rod body 11. The outer circumferential surface of the worm wheel is provided with tooth grooves. The worm includes a transmission section that cooperates with the worm wheel and a winding section for winding the connecting cable 13. The connecting cable 13 is connected to the winding section.

[0110] In some embodiments, the drive structure 14 includes an operating member 143, and a connecting cable 13 is connected between the operating member 143 and the second rod 12. The operating member 143 has a locked position close to the second rod 12 and a relaxed position away from the second rod 12. When the operating member 143 moves from the relaxed position to the locked position, it can drive the connecting cable 13 to tighten the first rod 11 and the second rod 12.

[0111] In the above embodiment, when the control member 143 moves from the relaxed position to the locking position in the direction close to the second rod 12, the connecting cable 13 can be tightened, thereby tightening the first rod 11 and the second rod 12 to achieve the connection and fixation of the two, which is very convenient and quick to operate.

[0112] Specifically, a guide post is fixedly installed inside the first rod 11. Preferably, the extension direction of the guide post is perpendicular to the central axis of the first rod 11, that is, the guide post is placed horizontally inside the first rod 11. One end of the operating member 143 extends into the first rod 11. The first end of the connecting cable 13 is connected to the second rod 12, and the second end crosses the guide post and connects to the operating member 143. When the operating member 143 moves towards the second rod 12, the middle part of the connecting cable 13 is blocked by the guide post, and the second end moves towards the first end under the action of the operating member 143. This causes the connecting cable 13 to bend at the guide post, and the shape of the entire connecting cable 13 gradually approaches a U-shape, making the connecting cable 13 taut and realizing the connection between the first rod 11 and the second rod 12. Conversely, when the operating member moves away from the second rod 12, the connecting cable 13 switches from a taut state to a slack state, relaxing the second rod 12.

[0113] Optionally, the operating component 143 includes a pull ring disposed on the outer side of the end of the first rod 11, which not only facilitates push-pull operation by the user, but also allows the entire cleaning tool to be suspended and stored when not in use. The operating component 143 also includes a pull rod fixedly disposed within the pull ring, the pull rod extending into the first rod 11 and connected to the connecting cable 13.

[0114] In some embodiments, the connecting cable 13 is a rope fixedly connected to the operating member 143.

[0115] In the above embodiments, the connecting cable 13 is in the form of a rope, which has a simple structure, low cost, and is easy to pull and wind.

[0116] In some embodiments, combined with Figure 3 As shown in the figure, it also includes a locking structure 15, which is disposed between the first rod 11 and the drive structure 14 for locking the drive structure 14.

[0117] In the above embodiment, the locking structure 15 provided between the first rod 11 and the driving structure 14 can lock the driving structure 14, prevent the driving structure 14 from moving arbitrarily, and ensure the stability and reliability of the connection between the first rod 11 and the second rod 12.

[0118] In some embodiments, when the drive structure 14 rotates, it can pull the end of the connecting cable 13 connected to the second rod 12; the locking structure 15 includes a limiting groove 151 and a ratchet 152; one of the limiting groove 151 and the ratchet 152 is disposed on the first rod 11 and the other is disposed on the drive structure 14, and the ratchet 152 cooperates with the limiting groove 151 to restrict the reverse rotation of the drive structure 14.

[0119] In the above embodiment, by controlling the drive structure 14 to rotate in a preset locking direction, the end of the connecting cable 13 connected to the second rod 12 can be pulled, and the first rod 11 and the second rod 12 can be tightened to achieve the connection and fixation of the two. The locking structure 15, by adopting the design of the limiting groove 151 and the ratchet 152, ensures that the drive structure 14 can only rotate in the preset locking direction and will not rotate in the opposite direction, thus avoiding the phenomenon that the drive structure 14 rotates in the opposite direction to release the connecting cable 13, causing the connection between the first rod 11 and the second rod 12 to fail.

[0120] Specifically, a limiting groove 151 is disposed on the inner periphery of the end of the first rod 11 away from the second rod 12, and a ratchet 152 is disposed on the outer periphery of the drive structure 14. There are multiple limiting grooves 151 and ratchet 152, with each pair corresponding to a specific element, or N ratchet 152 corresponding to one limiting groove 151, where N ≥ 2. The multiple ratchet 152 are inclined in the same direction on the outer periphery of the drive structure 14, and the inclination direction of the ratchet 152 conforms to the aforementioned preset locking direction, preventing jamming. When the drive structure 14 rotates in the opposite direction, the ratchet 152 will abut against the limiting groove 151, restricting the reverse rotation of the drive structure 14, thereby achieving unidirectional transmission of the drive structure 14.

[0121] Preferably, the limiting tooth groove 151 is an oblique tooth groove to guide the drive structure 14 to rotate only in one direction.

[0122] Specifically, one side of the limiting tooth groove 151 is provided with an inclined guide surface 1511, and the other side is provided with a straight limiting surface 1512. The guide surface 1511 is used to guide the ratchet 152 to rotate in a preset locking direction, so that the drive structure 14 rotates more smoothly in the preset locking direction. The limiting surface 1512 is used to resist and cooperate with the ratchet 152 when the ratchet 152 has a tendency to rotate in the opposite direction, thereby restricting the reverse rotation of the drive structure 14.

[0123] In other alternative embodiments, the locking structure 15 includes a latch and a slot; one of the latch and the slot is disposed on the first rod 11 and the other is disposed on the drive structure 14. When the drive structure 14 is rotated to a preset position, the latch and the slot cooperate to lock the drive structure 14.

[0124] In the above embodiment, when the drive structure 14 rotates along the preset locking direction, it can wind the connecting cable 13. When the drive structure 14 rotates to a preset position where the length of the connecting cable 13 is sufficient to tighten and fix the first rod 11 and the second rod 12, the buckle and the slot engage to lock the drive structure 14 to the preset position. This effectively prevents the drive structure 14 from moving arbitrarily and affecting the fixing effect of the first rod 11 and the second rod 12. Furthermore, the locking structure 15, by adopting the form of buckle and slot, has a simple structure, better stability and reliability, and is not easy to disengage.

[0125] In some embodiments, in combination with 3, Figure 8 , Figure 9 A limiting member 131 is provided at one end of the connecting cable 13 connected to the second rod 12; a limiting mating part 121 is provided inside the second rod 12, and a through hole 1210 is provided on the limiting mating part 121 for the connecting cable 13 to pass through. The limiting member 131 is blocked and limited on the side of the limiting mating part 121 away from the driving structure 14.

[0126] In the above embodiment, the limiting member 131 is limited to the side of the limiting mating part 121 away from the driving structure 14. One end of the connecting cable 13 is connected to the limiting member 131, and the other end passes through the limiting mating part 121 and is connected to the driving structure 14. The connection between the connecting cable 13 and the second rod 12 is realized in the above manner, making disassembly and assembly more convenient and quick.

[0127] Specifically, the outer diameter of the limiting member 131 is larger than the inner diameter of the through hole 1210 to ensure that the limiting member 131 can play an effective limiting role and ensure that the connecting cable 13 and the second rod 12 are reliably connected.

[0128] In some specific embodiments, the limiting member 131 is a limiting block, the width of which is greater than the diameter of the through hole 1210, so as to prevent the limiting block from passing through the through hole 1210.

[0129] In the above embodiments, the limiting member 131 adopts the form of a limiting block, which has a simple structure, strong load-bearing capacity, and high structural strength. Furthermore, by setting the width of the limiting block to be greater than the diameter of the through hole 1210, it can effectively prevent the limiting block from coming out of the through hole 1210, thereby improving the stability of the fit between the limiting block and the limiting mating part 121.

[0130] Of course, in other alternative implementations, the limiting member 131 can also take the form of a limiting rod, a limiting plate, a limiting post, or other structural forms.

[0131] Specifically, in this embodiment, the limiting fitting part 121 is disposed at the end of the second rod 12 away from the first rod 11, that is, the limiting fitting part 121 is fixedly disposed at the end of the second rod 12.

[0132] In one example, the limiting fitting part 121 includes a limiting fitting plate fixedly disposed within the second rod 12. Preferably, the limiting fitting plate is integrally formed with the second rod 12. More preferably, the longitudinal section of the limiting fitting plate is an inverted L-shape. The lower part of the L-shaped limiting fitting plate and the inner periphery of the second rod 12 form an accommodating space for accommodating the limiting member 131. The L-shaped limiting fitting plate includes a horizontal part transversely disposed within the second rod 12. A through hole 1210 is provided on the horizontal part for the connecting cable 13 to pass through.

[0133] In some embodiments, the second rod 12 includes multiple rod segments that are nested together.

[0134] According to an embodiment of the present invention, in another aspect, a cleaning tool is provided, including a segmented rod 10 and a cleaning head 20 as described in any of the above embodiments. A first rod 11 and a second rod 12 are connected by a connecting device. The cleaning head 20 is connected to one end of the second rod 12. The first rod 11 is a straight or curved handle located at the other end of the second rod 12.

[0135] In the above embodiments, the cleaning tool's cleaning rod adopts a segmented rod body 10 design, and the segmented rod bodies are connected by connecting cables 13. The connecting cables 13 are tightened by a drive structure 14, thus enabling the connection of multiple rod bodies. This simplifies assembly, increases stability, and allows the rods to be folded, saving space and reducing maintenance and transportation costs. This effectively solves the problems of complex and unstable assembly of segmented rod bodies 10 in existing cleaning tools, as well as their large space requirements during transportation. Furthermore, by constructing the first rod body 11 as a straight or curved handle, users can choose the appropriate type of cleaning tool as needed, resulting in a better user experience.

[0136] It should be noted that, in this embodiment, the cleaning tools include, but are not limited to, mops, brooms, and squeegees; preferably, the cleaning tool is a mop.

[0137] The following section uses a mop as an example to describe the specific structure, connection relationship, and assembly process of the segmented rod 10 in this embodiment.

[0138] The mop includes a mop handle and a cleaning head 20 connected to one end of the mop handle. The mop handle is a segmented handle 10, specifically, the mop handle is segmented and hollow. The mop handle includes a first rod 11 and a second rod 12, wherein one end of the second rod 12 is connected to the cleaning head 20 and the other end is connected to the first rod 11, and the first rod 11 is located above the second rod 12. The first rod 11 and the second rod 12 are connected by a connecting device, which includes a drive structure 14 and a connecting cable 13 connecting the drive structure 14 and the second rod 12. The drive structure 14 is disposed on the first rod 11.

[0139] Specifically, the drive structure 14 includes an operating member 143 located at the top of the first rod 11. The operating member 143 includes a pull ring, which can rotate around the central axis of the first rod 11. An input gear 1421 is located at the bottom of the pull ring, and an output gear 1422 is rotatably located inside the first rod 11. The input gear 1421 and the output gear 1422 mesh and drive each other. A winding roller 141 is coaxially fixed to the output gear 1422. One end of the connecting cable 13 is fixed to the winding roller 141, and the other end passes through the hollow areas of the first rod 11 and the second rod 12 in sequence, and passes through the through hole 1210 at the end of the second rod 12. It is limited to the end of the second rod 12 by a limiting member 131.

[0140] Furthermore, the user can rotate the pull ring to drive the input gear 1421 to rotate, which in turn drives the output gear 1422 to rotate. The output gear 1422 then drives the winding roller 141 to rotate, allowing the connecting cable 13 to wind around the winding roller 141. Shortening the length of the connecting cable 13 secures the segmented first rod 11 and second rod 12 together, preventing them from detaching. A locking structure 15 is provided at the engagement position of the pull ring and the second rod 12. The locking structure 15 is located above the input gear 1421 and can take the form of a snap and slot, or a ratchet 152 and a limiting slot 151. The locking structure 15 is used to lock the operating member 143 and the first rod 11 when the operating member 143 rotates to a preset position, meaning that once the rod is locked, it cannot be unlocked.

[0141] Of course, in other alternative implementations, the input gear 1421 and the output gear 1422 can also be replaced by threaded screws or worm gears. It should be noted that worm gears are only suitable for straight-tail mops.

[0142] In this embodiment, the mop handle is divided into two parts using the segmented rod 10 described above. During transportation, the second rod can be nested inside the first rod, saving packaging space, saving energy and protecting the environment, reducing costs, and improving the flexibility of the rod during transportation and handling. Furthermore, the modular assembly structure reduces packaging materials, saves packaging and transportation space, and simplifies installation, allowing for quick docking or disassembly of the two parts.

[0143] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
