Description

Technical Field

[0001] The utility model relates to the technical field of cleaning appliances, and particularly relates to a rod module and a mop. Background Art

[0002] As a common cleaning appliance, the mop is simple and inexpensive, and has strong decontamination ability, and is a necessary tool at home. Nowadays, in order to expand different functions, movable additional structures are added to the mop rod, such as a water squeezing rack sleeved on the mop rod of a hands-free washing mop.

[0003] The mop board and the mop rod of the hands-free washing mop can rotate relative to each other. When the mop board rotates to a state parallel to the mop rod, the water squeezing rack slides along the rod body of the mop rod, so that the mop board repeatedly enters the extrusion opening of the water squeezing rack. A scraping member is arranged in the extrusion opening, and can clean the wiping objects on the mop board.

[0004] However, these movable additional structures, such as the water squeezing rack, are still installed on the mop rod after use. When the user uses the mop to mop the floor, the mop board needs to be moved back and forth. If these movable additional structures still move along the mop rod under the action of inertia, they will frequently hit the mop board, affecting the use experience and working life of the mop. Content of the Utility Model

[0005] In view of this, the utility model provides a rod module and a mop to solve the problem that the movable additional structures on the mop rod affect the use experience and working life during the working process of the mop.

[0006] In a first aspect, the utility model provides a rod module, which includes a rod body and a main body to be locked. The main body to be locked is sleeved on the rod body and includes: a first ring sleeve sleeved on the rod body, and a locking cooperation part is arranged thereon; a locking part is connected with the locking cooperation part. The locking part has a locking state in which, under the action of an external force, the first ring sleeve is driven to deform through the locking cooperation part, so that the first ring sleeve is in limit connection with the rod body, and an active state in which the first ring sleeve is driven to reset, so that the first ring sleeve is disengaged from the limit connection with the rod body. When the locking part is in the locking state, the first ring sleeve is used to limit the main body to be locked on the rod body.

[0007] Beneficial Effects:

[0008] A locking and mating portion is provided on a first collar sleeved on a rod body, and a locking portion is correspondingly provided for mating. The locking portion can adjust the locking and mating portion under the drive of an external force, thereby driving the deformation or reset of the first collar, changing the connection state between the first collar and the rod body, and further changing the connection state between the main body to be locked and the rod body. With this arrangement, the user can manually adjust the locking portion to control the sliding or limiting of the main body to be locked along the rod body, preventing the main body to be locked from remaining in an active state on the rod body. For example, if the main body to be locked is a water wringer and the rod body is a mop rod, the user can manually adjust the locking portion to control the state of the water wringer on the mop rod, that is, the water wringer can slide along the mop rod or be limited on the mop rod, so that the mop wiping material can be cleaned when the water wringer slides along the mop rod. When the user uses the mop, the water wringer can be fixed on the mop rod to avoid problems that affect the user experience and the working life of the mop. If the main body to be locked is a sleeve for controlling the detachment of the wiping material, the user can manually adjust the locking portion to control the state of the sleeve on the mop rod, that is, the sleeve can slide along the mop rod or be limited on the mop rod, so that the sleeve can control the detachment of the wiping material from the mop plate when the sleeve slides along the mop rod, and the fixed state of the wiping material is maintained when the sleeve is fixed to the mop rod.

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0033] As Figures 1-7 , the present utility model provides a rod module, including a rod body and a main body 2 to be locked. The rod body is arranged in a straight rod shape, and the main body 2 to be locked can be sleeved on the rod body.

[0034] In the embodiments of the present utility model, taking the application of this rod module to a mop as an example for illustration, that is, the rod body is the mop rod 1, and the main body 2 to be locked can be an additional movable structure added to the mop rod 1 to expand different functions, such as a wringer, a sleeve for disassembling wiping objects, an operating member for controlling water spraying at the end of the mop rod, etc. The mop includes: a first ring sleeve 3 and a locking part 4. In practical applications, this rod module can also be applied to other cleaning tools, or other scenarios where the main body 2 to be locked needs to be locked or unlocked relative to the rod body. The embodiments of the present utility model do not limit this.

[0035] Among them, the first ring sleeve 3 is sleeved on the mop rod 1, and a locking mating part 32 is arranged on the first ring sleeve 3.

[0036] The locking part 4 is connected to the locking cooperation part 32, and the locking part 4 has a locked state and an active state. When in the locked state, the locking part 4 drives the first ring sleeve 3 to deform through the locking cooperation part 32 under the action of an external force, so that the first ring sleeve 3 is connected to the mop rod 1 in a limiting manner. When in the active state, the locking part 4 drives the first ring sleeve 3 to reset through the locking cooperation part 32 under the action of an external force, so that the first ring sleeve 3 is disengaged from the limiting connection with the mop rod 1 and can move along the mop rod 1.

[0037] When the locking part 4 is in the locked state, the first ring sleeve 3 is used to limit the main body 2 to be locked on the mop rod 1. In this embodiment, the first ring sleeve 3 is arranged on the main body 2 to be locked.

[0038] The locking cooperation part 32 is arranged on the first ring sleeve 3 sleeved on the mop rod 1, and the locking part 4 is correspondingly arranged in cooperation. The locking part 4 can adjust the locking cooperation part 32 under the drive of an external force, and then drive the first ring sleeve 3 to deform or reset, changing the connection state between the first ring sleeve 3 and the mop rod 1, and further changing the connection state between the main body 2 to be locked and the mop rod 1. With such a setting, the user can manually adjust the locking part 4, and then control the main body 2 to be locked to slide or be limited along the mop rod 1, avoiding the problem that the main body 2 to be locked remains in an active state on the mop rod 1, which affects the user experience and the working life of the mop.

[0039] As a variable embodiment, the first ring sleeve 3 can also be separated from the main body 2 to be locked, that is, arranged in cooperation with the mop rod 1. The locking part 4 can adjust the locking cooperation part 32 on the first ring sleeve 3 under the drive of an external force, and then drive the first ring sleeve 3 to deform or reset, changing the connection state between the first ring sleeve 3 and the mop rod 1. When the first ring sleeve 3 deforms and is connected to the mop rod 1 in a limiting manner, when the main body 2 to be locked moves to a position where it abuts against the first ring sleeve 3, it cannot move further, that is, the main body 2 to be locked is limited on the mop rod 1; after the first ring sleeve 3 resets and is disengaged from the mop rod 1, there is no longer any limit between the first ring sleeve 3 and the mop rod 1, and the main body 2 to be locked can continue to move along the mop rod 1. Specifically, at least two first ring sleeves 3 can be set to jointly limit the main body 2 to be locked.

[0040] For example, the first ring sleeve 3 further includes a first main body 31.

[0041] The first main body 31 is wound around the outer periphery of the mop rod 1. The two ends extending in the circumferential direction are respectively a first end 311 and a second end 312. The first end 311 and the second end 312 are oppositely arranged to jointly form a locking and mating part 32. The locking and mating part 32 is arranged on the side of the first main body 31 away from the mop rod 1. In this embodiment, the first end 311 and the second end 312 can be abutted against each other so that the first main body 31 forms a closed ring shape. The shape of the inner peripheral wall of the first main body 31 corresponds to and matches the shape of the outer peripheral wall of the mop rod 1. The inner diameter of the first main body 31 is slightly larger than the outer diameter of the mop rod 1, so that it can be limited on the mop rod 1 through deformation and has a clearance fit with the mop rod 1 when reset.

[0042] As a changeable implementation manner, the first end 311 and the second end 312 can also be spaced apart from each other so that the first main body 31 forms an arc shape or a partially annular shape to be opened. The locking and mating part 32 includes a first mating sub-part 321 and a second mating sub-part 322. The first mating sub-part 321 is arranged on the first end 311, and the second mating sub-part 322 is arranged on the second end 312. Both are arranged on the side of the first main body 31 away from the mop rod 1.

[0043] In this embodiment, when the first main body 31 is wound around the outer periphery of the mop rod 1, the first end 311 and the second end 312 are abutted against each other, so that the first mating sub-part 321 and the second mating sub-part 322 form a guiding main body. The locking part 4 is connected to the guiding main body. The locking part 4 is used to drive the guiding main body to move under the action of an external force.

[0044] When the moving direction is away from the mop rod 1, the guiding main body drives the locking area of the first main body 31 to move in the direction close to the mop rod 1 until it is in close contact with the mop rod 1. When the moving direction is close to the mop rod 1, the guiding main body drives the locking area of the first main body 31 to move in the direction away from the mop rod 1 until there is a gap between it and the mop rod 1.

[0045] In this embodiment, when the guiding main body moves away from the mop rod 1, it drives the first main body 31 to undergo structural deformation. When the guiding main body moves close to the mop rod 1, it drives the first main body 31 to be reset to a ring shape. The ring-shaped first main body 31 has a clearance fit with the mop rod 1. In this embodiment, a part of the first main body 31 is deformed towards the mop rod 1. This part of the structure of the first main body 31 is the locking area. In this implementation, the locking area is on the side away from the guiding main body and is oppositely arranged to the guiding main body.

[0046] When the locking area is in close contact with the mop rod 1, the frictional force between the two limits them to each other, and the locking part 4 is in a locked state. When there is a gap between the locking area and the mop rod 1, the locking part 4 is in an active state.

[0047] As a transformable embodiment, when the first main body 31 is in an arc shape or a partially annular shape to be opened, the first fitting portion 321 and the second fitting portion 322 can be spaced apart from each other and adjacent in position, and the locking portion 4 can still connect the two together, driving the first fitting portion 321 and the second fitting portion 322 to gradually approach or move away from each other, thereby tightening or resetting the first main body 31, and further changing the connection state between the first collar 3 and the mop rod 1.

[0048] The locking and fitting portion 32 further includes: a receiving cavity 324, a positioning portion 325, and a positioning and fitting portion 326. The receiving cavity 324 is formed by enclosing the first fitting portion 321 and the second fitting portion 322, providing an installation space for the positioning portion 325 and the positioning and fitting portion 326; the positioning portion 325 is disposed in the receiving cavity 324, and is correspondingly disposed on one of the first fitting portion 321 and the second fitting portion 322, and protrudes toward the other one of them. Preferably, the positioning portion 325 is in a cylindrical shape or a frustum shape, and a guiding inclined surface or a guiding round end can be provided at its front end.

[0049] The positioning and fitting portion 326 is disposed in the receiving cavity 324, and is correspondingly disposed on the other one of the first fitting portion 321 and the second fitting portion 322, and is disposed opposite to the positioning portion 325, and is adapted to receive the limiting and positioning portion 325. Preferably, the positioning portion 325 is in a circular groove shape or a cylindrical shape.

[0050] By providing the mutually cooperating positioning portion 325 and the positioning and fitting portion 326, positioning can be provided for the first fitting portion 321 and the second fitting portion 322 to jointly form a guiding main body, avoiding structural deviation between the first fitting portion 321 and the second fitting portion 322, and ensuring the structural stability of the guiding main body.

[0051] In this embodiment, the locking portion 4 and the locking and fitting portion 32 are rotatably and cooperatively connected, and the locking portion 4 rotates relative to the locking and fitting portion 32 and switches between a locked state and an active state. The way of rotational connection makes the movement range of the locking portion 4 relatively small, effectively avoiding interference with other structures on the mop rod 1. In addition, at least one of the locking portion 4 and the locking and fitting portion 32 is provided with a rotational guiding structure to cooperate with the relative rotation of the two to drive the state change of the locking and fitting portion 32. In this embodiment, the rotational guiding structure is a threaded structure, and can also be a gear structure or the like.

[0052] The locking part 4 includes: a base part 41, a first locking part 42 and a second locking part 43. Among them, the base part 41 is the basis for carrying the first locking part 42 and the second locking part 43. Preferably, the outer edge of the base part 41 is circular, which is convenient for the user to hold and rotate. It can also be other shapes, such as square, etc. Further preferably, a rotation direction mark 411 can be set on the outer side surface of the base part 41, and an anti-slip structure 433 can be set on the peripheral side wall exposed for the user to hold and apply force.

[0053] The first locking part 42 is arranged on the base part 41 and is rotatably and cooperatively connected with the locking cooperation part 32. In this embodiment, at least one of the first locking part 42 and the locking cooperation part 32 is provided with a rotation guiding structure, which can specifically be a thread structure.

[0054] The second locking part 43 is arranged on the base part 41 and is rotatably connected with the main body 2 to be locked in this embodiment. Preferably, the two are in movable limit. As an alternative embodiment, the second locking part 43 can also be rotatably connected with the mop rod 1 and is detachably and limit-connected.

[0055] Furthermore, the base part 41 is driven to drive the first locking part 42 to rotate relative to the locking cooperation part 32, and the second locking part 43 rotates relative to the main body 2 to be locked or the mop rod 1, so that the locking cooperation part 32 moves in a direction approaching or away from the mop rod 1, and further drives the first ring sleeve 3 to deform or drives the first ring sleeve 3 to reset.

[0056] In this embodiment, a second guiding part 44 is arranged on the first locking part 42. The second guiding part 44 is specifically an internal thread. A first guiding part 323 is arranged on the locking cooperation part 32 of the main body 2 to be locked. The first guiding part 323 is specifically an external thread. The two are rotationally guided and cooperated, specifically in a thread cooperation. As an alternative embodiment, the first locking part 42 can be provided with a protruding rotation guiding structure and an external thread is correspondingly arranged, and the locking cooperation part 32 of the main body 2 to be locked is provided with an inner cylinder and an internal thread is correspondingly arranged.

[0057] In addition, in this embodiment, the first locking part 42 is fixedly connected with the base part 41, and the two are arranged on the same rotation axis. The base part 41 is adapted to rotate along the rotation axis under the action of an external force.

[0058] With such a setting, combined with the second locking part 43 being rotatably connected to the main body 2 to be locked or the mop rod 1 and being movably limited, on the one hand, the main body 2 to be locked or the mop rod 1 provides an installation basis for the second locking part 43, and on the other hand, the main body 2 to be locked or the mop rod 1 can provide stable limitation for the locking part 4. In cooperation, the first locking part 42 is fixedly connected to the base part 41, and the two are arranged on the same rotation axis, ensuring that when the second locking part 43 rotates relative to the main body 2 to be locked or the mop rod 1, only circumferential displacement occurs, avoiding axial movement, and further causing the locking and mating part 32 connected to the first locking part 42 also arranged on the base part 41 to correspondingly move axially.

[0059] The second locking part 43 includes: a ring body 431 and at least one engaging part 432. Among them, the ring body 431 is connected to the base part 41 and jointly formed into a circular groove structure. The ring body 431 is correspondingly set as the groove wall of the circular groove structure, and the base part 41 is correspondingly set as the groove bottom of the circular groove structure. The ring body 431 is adapted to receive an external force.

[0060] The engaging part 432 is arranged on the ring body 431. In this embodiment, a plurality of engaging parts 432 are arranged and distributed circumferentially along the rotation axis of the base part 41. Preferably, the distribution intervals of the engaging parts 432 are evenly set to facilitate uniform force application. It can be understood that only one or two engaging parts 432 can be provided. In this embodiment, the engaging part 432 and the main body 2 to be locked are mutually limited in the axial direction along the rotation axis of the base part 41 and are movably mated in the circumferential direction. As a changeable implementation manner, the engaging part 432 can be rotatably connected to the mop rod 1.

[0061] In an achievable embodiment, the first ring sleeve can be arranged on the main body 2 to be locked. At this time, the main body 2 to be locked can include a second main body 21. The second main body 21 is in a cylindrical shape and sleeved on the mop rod 1. The locking part 4 is arranged on the second main body 21. An installation groove is provided on the second main body 21 to accommodate the first ring sleeve 3. The installation groove is provided with a lateral opening 22, and the opening direction of the lateral opening 22 is arranged along the radial direction of the cylinder body of the second main body 21. The locking and mating part 32 of the first ring sleeve 3 is exposed at the position of the lateral opening 22. In this embodiment, the locking part 4 is connected to the locking and mating part 32 and arranged on the second main body 21.

[0062] Preferably, the locking part 4 is rotatably mated with the second main body 21 through the ring body 431. Further, the main body 2 to be locked further includes a side ring part 23 and a lateral mating part 24.

[0063] The side ring portion 23 is arranged on the second main body 21 in a ring-shaped convex form. Its structure surrounds the lateral opening 22. The side ring portion 23 and the ring body 431 are sleeved with each other. The lateral fitting portion 24 is arranged in the circumferential direction of the side ring portion 23 and is used for limiting and fitting with the ring body 431, specifically for limiting and fitting with the engaging portion 432 on the ring body 431. It can be understood that the lateral fitting portion 24 can also be used for limiting and fitting with the inner wall or the outer wall of the ring body 431. In this embodiment, under the drive of an external force, the ring body 431 rotates circumferentially relative to the side ring portion 23, and the relative positions of the two in the axial direction remain unchanged.

[0064] In this embodiment, the ring body 431 is sleeved on the outside of the side ring portion 23. The engaging portion 432 on the ring body 431 is correspondingly arranged on the inner wall of the ring body 431, and the lateral fitting portion 24 is correspondingly arranged on the outer wall of the side ring portion 23. The two are in movable limiting fit, that is, the lateral fitting portion 24 and the engaging portion 432 are movable in the circumferential direction of the side ring portion 23, so that the locking portion 4 can rotate relative to the main body 2 to be locked; they are limited in the axial direction of the side ring portion 23 to prevent the locking portion 4 from detaching from the main body 2 to be locked.

[0065] As a transformable embodiment, the ring body 431 is arranged inside the side ring portion 23. The engaging portion 432 on the ring body 431 is correspondingly arranged on the outer wall of the ring body 431, and the lateral fitting portion 24 is correspondingly arranged on the inner wall of the side ring portion 23.

[0066] Furthermore, in this embodiment, the outer periphery of the lateral fitting portion 24 is a convex, preferably a ring convex. The inner wall of the ring body 431 or the engaging portion 432 is arranged as an annular groove. When the locking portion 4 rotates relative to the second main body 21, the engaging portion 432 in the form of an annular groove slides relative to the lateral fitting portion 24 in the form of a convex. Specifically, the two are movably connected in the circumferential direction and are limited with each other in the axial direction.

[0067] As a transformable embodiment, the outer periphery of the lateral fitting portion 24 is an annular groove, and the inner wall of the ring body 431 or the engaging portion 432 is arranged as a convex.

[0068] In a second aspect, this embodiment further includes a mop, which includes the above-mentioned rod module. The rod body is specifically the mop rod of the mop, and the main body to be locked is a water squeezing frame or a sleeve sleeved on the rod body.

[0069] Although the 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 scope defined by the appended claims.
