[0106] Reference below Figure 1-Figure 14 A mop 100 according to an embodiment of the present invention is described.

[0107] like Figure 1-Figure 14 As shown, the mop 100 according to the embodiment of the utility model comprises: a mop rod 10, a mounting structure 20, a lock core 30, an elastic arm 40 and an operating member 50, and the end of the mop rod 10 (such as Figure 1 The lower end of the mop handle 100 may be provided with a mop plate 80, and the mop plate 80 may rotate relative to the mop rod 10. The mop 100 also has a water squeezing frame 70, which may be extended along the extension direction of the mop rod 10 (such as Figure 1 Thus, when the mop board 80 is rotated to have an extending direction that is the same as the extending direction of the mop rod 10, the squeezing rack 70 can move relative to the mop board 80 to squeeze and scrape the mop board 80.

[0108] The mounting structure 20 may be disposed on the mop rod 10; or, the mop plate 80 may be provided with a to-be-locked portion 60, the mounting structure 20 may be disposed on the to-be-locked portion 60, and the to-be-locked portion 60 may be disposed along the extension direction of the mop rod 10 (eg, Figure 1The locking portion 60 can be connected to the water squeezing rack 70, whereby the movement of the locking portion 60 can drive the water squeezing rack 70 to move, and the mounting structure 20 and the locking portion 60 can move together.

[0109] The mounting structure 20 is provided with a through hole 201, and the lock core 30 includes a core body 31, which is movably provided at the through hole 201. The core body 31 can extend out of the through hole 201 to lock the to-be-locked portion 60 with the mop rod 10, and can prevent the to-be-locked portion 60 from extending along the extension direction of the mop rod 10 (such as Figure 1 and the core 31 can be retracted into the through hole 201 to unlock the locking portion 60 and the mop rod 10, which is conducive to the locking portion 60 along the extension direction of the mop rod 10 (such as Figure 1 up and down directions) as shown.

[0110] The elastic arm 40 can be connected to the lock core 30, that is, the elastic arm 40 can be arranged on the lock core 30, so that the mounting structure 20 can drive the elastic arm 40 to undergo elastic deformation when the core body 31 extends out of the through hole 201; or, the elastic arm 40 can abut against the lock core 30, that is, the elastic arm 40 can be arranged on the mounting structure 20, so that the lock core 30 can drive the elastic arm 40 to undergo elastic deformation when the core body 31 extends out of the through hole 201; thereby, the elastic arm 40 can restore its original shape after deformation to drive the core body 31 to retract into the through hole 201, which can improve the smoothness of unlocking the to-be-locked portion 60 and the mop rod 10 and facilitate operation.

[0111] The position of the operating member 50 corresponds to the position of the lock core 30. The operating member 50 is used to drive the core 31 to extend out of the through hole 201 to lock the portion to be locked 60 with the mop rod 10, and can prevent the portion to be locked 60 from moving relative to the mop rod 10, and prevent the portion to be locked 60 from moving under the action of inertia. At the same time, the elastic arm 40 can be elastically deformed during the process of locking the portion to be locked 60 with the mop rod 10, so that the elastic arm 40 can restore the initial shape to drive the core 31 to move, that is, the elastic arm 40 is used to drive the core 31 to retract into the through hole 201 to unlock the portion to be locked 60 with the mop rod 10, so that the portion to be locked 60 can move along the extension direction of the mop rod 10 (such as Figure 1 The present application adopts the elastic arm 40 to provide the restoring force, which is simple to manufacture, has low production cost, saves space and has a long service life.

[0112] According to the mop 100 of the embodiment of the utility model, by providing a movable lock core 30 on the mop rod 10 or the part to be locked 60, and by providing an operating member 50 to drive the lock core 30 to move, the part to be locked 60 can be locked with the mop rod 10, and the part to be locked 60 can be prevented from moving relative to the mop rod 10, and the part to be locked 60 can be prevented from moving under the action of inertia, so that the squeezing rack 70 can be prevented from hitting the mop plate 80 when the mop 100 is mopping the floor, and the service life of the mop 100 can be improved; or, by driving the lock core 30 to move, the part to be locked 60 can be unlocked from the mop rod 10, so that the part to be locked 60 can move along the extension direction of the mop rod 10.

[0113] According to the mop 100 of the embodiment of the present invention, the locking portion 60 includes a telescopic rod, which is sleeved on the mop rod 10, and the telescopic rod can be extended along the extension direction of the mop rod 10 (such as Figure 1 The mop rod 10 can be moved in the up and down directions (as shown in the figure), and a water squeezing rack 70 is also provided on the mop rod 10. The telescopic rod can be connected to the water squeezing rack 70, so that the telescopic rod can drive the water squeezing rack 70 to move along the extension direction of the mop rod 10 to squeeze and scrape the mop plate 80; or, the movement of the telescopic rod can drive the water squeezing rack 70 to move.

[0114] The telescopic rod can be sleeved inside or outside the mop rod 10, and can move relative to the mop rod 10 to extend or shorten the length of the entire rod body of the mop, so that the rod body length of the mop can be adjusted. For example, the mop rod 10 can be adjusted in length. When adjusted to the shortest or shorter position, it can be used for children, or when adjusted to the shortest or shorter position, it can be used to wipe countertops and lower walls; when adjusted to the longest or longer position, it can be used for normal mopping. The above locking structure can prevent the telescopic rod from moving relative to the mop rod 10, which affects the adjustment of the rod body length.

[0115] like Figure 1 and Figure 2 As shown, according to the mop 100 of the embodiment of the utility model, the locking portion 60 includes a connecting sleeve, which can be sleeved on the mop rod 10, and the connecting sleeve can be extended along the extension direction of the mop rod 10 (such as Figure 1 The mop rod 10 is also provided with a water squeezing rack 70, and the connecting sleeve can be connected to the water squeezing rack 70, so that the movement of the connecting sleeve can drive the water squeezing rack 70 to move along the extension direction of the mop rod 10, so as to realize the squeezing and scraping of the mop plate 80.

[0116] Thus, the squeezing rack 70 can be prevented from hitting the mop plate 80 when the mop 100 is mopping the floor, and the service life of the mop 100 can be improved. At the same time, the elastic arm 40 can be elastically deformed during the process of locking the waiting portion 60 and the mop rod 10, so that the elastic arm 40 can restore the initial shape to drive the core 31 to move, that is, the elastic arm 40 is used to drive the core 31 to retract into the through hole 201 to unlock the waiting portion 60 and the mop rod 10, so that the waiting portion 60 can move along the extension direction of the mop rod 10 (such as Figure 1 The water squeezing frame 70 moves in the up and down directions (as shown) to drive the water squeezing frame 70 to move relative to the mop plate 80, so as to squeeze and scrape the mop plate 80.

[0117] like Figure 4 , Figure 5 , Figure 8 and Fig.12 As shown, in some examples, the operating member 50 can be set on the mounting structure 20, and the operating member 50 can rotate relative to the mounting structure 20. The rotation of the operating member 50 can drive the core 31 to extend out of the through hole 201, which can reduce the probability of the core 31 being driven to extend out of the through hole 201 due to accidental touch by the user, and is easy to operate; in addition, compared with the technical solution of using a press-type structure to drive the core 31 to move, it can save space and is beneficial to improving the aesthetics of the mop 100.

[0118] In some examples, when the elastic arm 40 abuts against the lock core 30, an abutting surface is provided on the lock core 30, and the abutting surface faces the extending direction of the lock core 30 extending out of the through hole 201 (such as Figure 5 In the direction from front to back as shown in the figure, the elastic arm 40 can be arranged on the mounting structure 20. During the process of locking the portion to be locked 60 and the mop rod 10, the elastic arm 40 can abut against the abutting surface, so that the elastic arm 40 can be elastically deformed when the core body 31 of the lock cylinder 30 extends out of the through hole 201, so that the elastic arm 40 can restore its original shape after deformation to drive the core body 31 to retract into the through hole 201, which can improve the smoothness of unlocking the portion to be locked 60 and the mop rod 10.

[0119] The abutment method makes it easier to install and remove the elastic arm 40, and is convenient for maintenance and replacement, and the arrangement method is simple and the production cost is lower. A groove can be arranged on the side of the lock core 30, and the side wall of the groove forms the abutment surface. The elastic arm 40 is arranged in the groove and abuts against the side wall corresponding to the groove. The abutment surface can be a flat surface or a curved surface.

[0120] It is understandable that the user can drive the operating member 50 to rotate after the locking portion 60 and the mop rod 10 are locked to unlock the locking portion 60 and the mop rod 10, so that the elastic arm 40 can apply a force to the core 31 when the locking portion 60 and the mop rod 10 are unlocked, so that the locking portion 60 and the mop rod 10 are quickly unlocked, which is convenient for operation.

[0121] In some examples, the fixed end of the spring arm 40 can be connected to the mounting structure 20, and the free end of the spring can abut against the lock core 30, that is, the spring arm 40 can be set on the mounting structure 20, so that the lock core 30 moves to drive the spring arm 40 to elastically deform. This arrangement can not only effectively fix the spring arm 40, but also abut the other end, and the production method is simple and low-cost.

[0122] In some examples, such as Figure 4 , Figure 5 , Figure 8 and Fig.12 As shown, the fixed end of the elastic arm 40 can be connected to the lock core 30, and the free end of the elastic arm 40 can abut against the mounting structure 20, that is, the elastic arm 40 can be arranged on the lock core 30, so that the elastic arm 40 can be elastically deformed when the core 31 of the lock core 30 extends out of the through hole 201, so that when the user rotates the operating member 50, and after the elastic arm 40 is deformed, the elastic arm 40 can restore the initial shape to drive the core 31 to retract into the through hole 201, which can improve the smoothness of unlocking the to-be-locked portion 60 and the mop rod 10. This arrangement can not only effectively fix the elastic arm 40, but also abut the other end, and the production method is simple and the cost is low.

[0123] Among them, the user can drive the operating member 50 to rotate after the locking portion 60 and the mop rod 10 are locked to unlock the locking portion 60 and the mop rod 10, so that the elastic arm 40 can apply a force to the core body 31 when the locking portion 60 and the mop rod 10 are unlocked, so that the locking portion 60 and the mop rod 10 are quickly unlocked, which is convenient for operation.

[0124] It should be noted that Figure 5 Taking the elastic arm 40 on the upper middle side as an example, if the elastic arm 40 is arranged on the mounting structure 20, the fixed end of the elastic arm 40 is as follows: Figure 5 The upper end shown, the free end of the elastic arm 40 is as shown Figure 5 As shown in the lower end, if the elastic arm 40 is provided on the lock core 30, the fixed end of the elastic arm 40 is as follows Figure 5 The lower end shown, the free end of the elastic is as shown Figure 5 shown at the upper end; Figure 5 Taking the elastic arm 40 at the middle and lower side as an example, if the elastic arm 40 is arranged on the mounting structure 20, the fixed end of the elastic arm 40 is as follows: Figure 5 The lower end shown, the free end of the elastic arm 40 is as shown Figure 5 As shown in the upper end, if the elastic arm 40 is provided on the lock core 30, the fixed end of the elastic arm 40 is as follows Figure 5 The upper end shown, the free end of the elastic is as shown Figure 5 The upper end shown.

[0125] like Figure 5As shown, in some examples, the number of elastic arms 40 is set to at least two, and each elastic arm 40 is evenly arranged around the outer periphery of the lock core 30. For example, the number of elastic arms 40 can be two, and the two elastic arms 40 can be evenly arranged around the outer periphery of the lock core 30, so that the core body 31 can be evenly stressed when the two elastic arms 40 are elastically deformed, which can ensure the normal movement of the core body 31 and prevent the core body 31 from tilting during the movement. Therefore, it can ensure that the locked portion 60 and the mop rod 10 are normally locked or unlocked, and by controlling the number of elastic arms 40, the cost can be reduced on the basis of ensuring the normal movement of the core body 31.

[0126] In some examples, the number of elastic arms 40 can be more, for example, the number of elastic arms 40 is four, and the four elastic arms 40 can be evenly arranged around the outer periphery of the lock core 30, which can increase the contact area between the elastic arms 40 and the mounting structure 20, improve the uniformity of the force on the core 31 when the elastic arms 40 are elastically deformed, and improve the stability of the movement of the core 31, thereby improving the stability of unlocking or locking the to-be-locked portion 60 and the mop rod 10, and improving the reliability of the product. And using at least two elastic arms 40 can share the force, extend the service life of each elastic arm 40, and thus extend the service life of the mop.

[0127] In some examples, the elastic arm 40 includes an annular elastic arm 40, which can extend circumferentially around the lock core 30, and can further increase the contact area between the elastic arm 40 and the mounting structure 20, so as to further improve the uniformity of the force applied to the core body 31 when the elastic arm 40 undergoes elastic deformation, and can improve the stability of the movement of the core body 31, and can improve the stability of unlocking or locking the part to be locked 60 and the mop rod 10. Based on improving product reliability, it is easy to process, and the use of an annular structure can further reduce stress concentration during use, and can further extend the service life of the elastic arm 40.

[0128] like Figure 4 , Figure 5 and Figure 8 As shown, in some examples, an avoidance space is provided on the mounting structure 20, and the avoidance space is used to avoid the deformation of the elastic arm 40. On the one hand, the elastic arm 40 can enter the avoidance space, and the lock core 30 can be limited to prevent the lock core 30 from rotating together with the operating member 50, so as to ensure that the part to be locked 60 and the mop rod 10 are normally locked or unlocked during the rotation of the operating member 50. On the other hand, by providing the avoidance space, a certain deformation space can be reserved for the elastic arm 40, so as to improve the uniformity of the elastic deformation of the elastic arm 40, prevent the elastic arm 40 from breaking due to the excessive concentration of the elastic deformation position, and improve the reliability of the product.

[0129] like Figure 4 and Figure 6As shown, in some examples, the elastic arm 40 has a working surface 41 , the mounting structure 20 is provided with a mounting surface 21 , the working surface 41 is arranged opposite to the mounting surface 21 , and the avoidance space is located between the working surface 41 and the mounting surface 21 .

[0130] Among them, the working surface 41 and the mounting surface 21 can both be planes, and there is an angle between the working surface 41 and the mounting surface 21, so that the elastic arm 40 can undergo elastic deformation during the process of locking or unlocking the to-be-locked portion 60 and the mop rod 10, which can improve the uniformity of the deformation of the elastic arm 40 during the process of locking or unlocking the to-be-locked portion 60 and the mop rod 10, improve the smoothness of locking or unlocking the to-be-locked portion 60 and the mop rod 10, facilitate operation, and facilitate processing, which can reduce processing costs.

[0131] Alternatively, the working surface 41 is a plane, and the mounting surface 21 includes a plane area 211 and a sloped area 212 arranged in sequence, and the avoidance space is located between the sloped area 212 and the working surface 41, so that the elastic arm 40 can first contact the plane area 211 when elastic deformation occurs, thereby increasing the force-bearing area of ​​the elastic arm 40, further improving the uniformity of deformation of the elastic arm 40, and preventing the elastic arm 40 from breaking due to the excessive concentration of the elastic deformation position, thereby improving the reliability of the product.

[0132] Of course, the working surface 41 can be a curved surface or a bent surface, and the mounting surface 21 can be a flat surface; or, the working surface 41 can be a flat surface, and the mounting surface 21 can be a curved surface or a bent surface; by setting the working surface 41 or the mounting surface 21 as a curved surface or a bent surface, the working surface 41 can always be in contact with the mounting surface 21 during the process of locking or unlocking the part to be locked 60 and the mop rod 10, so as to further improve the uniformity of deformation of the elastic arm 40 during the process of locking or unlocking the part to be locked 60 and the mop rod 10, and improve the smoothness of locking or unlocking the part to be locked 60 and the mop rod 10. At the same time, the elastic force of the elastic arm 40 can be increased to further speed up the unlocking speed of the part to be locked 60 and the mop rod 10, so as to facilitate operation.

[0133] It should be noted that the curved surface or the bent surface may include a curved top and a curved bottom, a slope is formed between the curved top and the curved bottom, and an escape space is formed between the slope and the plane. On the basis of ensuring that the elastic arm 40 undergoes elastic deformation during the process of locking or unlocking the locking portion 60 and the mop rod 10, the escape space can be increased, which is beneficial to reserving sufficient deformation space for the elastic arm 40, so as to further improve the uniformity of the elastic deformation of the elastic arm 40, reduce the probability of the elastic arm 40 breaking due to concentrated force, increase the service life of the elastic arm 40, and improve the reliability of the product.

[0134] like Figure 5 and Fig. 9As shown, in some examples, the lock core 30 is provided with a first inclined surface 33, and the operating member 50 is provided with a driving member 51, and the driving member 51 is arranged corresponding to the first inclined surface 33, and the first inclined surface 33 has an inclined top 331 and an inclined bottom 332, and the inclined top 331 is closer to the operating member 50 than the inclined bottom 332. When the operating member 50 rotates, the driving member 51 can move from the inclined bottom 332 to the inclined top 331 to drive the core body 31 in a direction away from the operating member 50 (such as Figure 5 The core 31 is driven to extend out of the through hole 201 to achieve locking of the to-be-locked portion 60 and the mop rod 10, and the elastic arm 40 is elastically deformed.

[0135] When the driving member 51 cancels the driving force on the lock core 30, the elastic arm 40 can return to a free state, that is, the elastic arm 40 can be deformed to return to the initial state, and when the user drives the operating member to rotate, the elastic arm 40 can drive the core 31 to a direction close to the operating member 50 (such as Figure 5 The elastic arm 40 can drive the core body 31 to retract into the through hole 201 to improve the smoothness of unlocking the to-be-locked portion 60 and the mop rod 10. At the same time, the driving member 51 moves from the inclined top 331 to the inclined bottom 332, so that the driving member 51 can continue to drive the core body 31 to extend out of the through hole 201 in subsequent operations, which is convenient for subsequent operations by users.

[0136] like Figure 5 and Fig. 9 As shown, in some examples, a second inclined surface 511 is provided on the driving member 51, and the second inclined surface 511 can be adapted to the first inclined surface 33, and the first inclined surface and the second inclined surface are arranged relative to each other, which can improve the smoothness of the movement of the driving member 51 to drive the core 31 and facilitate operation, wherein the second inclined surface 511 can have the same shape as the first inclined surface 33, that is, the second inclined surface 511 can have an inclined top and an inclined bottom, and the inclined top is closer to the core 31 relative to the inclined bottom, when the operating member 50 rotates, the inclined top of the second inclined surface 511 can move from the inclined bottom 332 of the first inclined surface 33 to the inclined top 331 of the first inclined surface 33, and the inclined bottom of the second inclined surface 511 can have a gap with the inclined bottom 332 of the first inclined surface 33, so as to drive the core 31 to extend out of the through hole 201.

[0137] It is understandable that the first bevel 33 can be a spiral surface, so that the transition of the slope change at different positions of the first bevel 33 is more uniform, which can ensure that the first bevel 33 is always compatible with the second bevel 511, and improve the smoothness of the movement of the driving member 51 driving the core 31.

[0138] like Figure 5As shown, in some examples, the number of the first inclined surfaces 33 is set to at least two, and the first inclined surfaces 33 are arranged sequentially in the circumferential direction to form an annular structure, so that the core body 31 can be uniformly stressed when the driving member 51 is driven, which can improve the uniformity of the stress on the core body 31 when the elastic arm 40 undergoes elastic deformation, improve the stability of the movement of the core body 31, and prevent the core body 31 from tilting during the movement, thereby improving the stability of locking or unlocking the to-be-locked portion 60 and the mop rod 10, and improving the reliability of the product.

[0139] like Figure 5 As shown, in some examples, the inclined top 331 of the first inclined surface 33 can be provided with a first limiting member 3311. When the core body 31 extends out of the through hole 201, the first limiting member 3311 can limit the movement of the driving member 51 to prevent the driving member 51 from excessively moving and moving to the inclined bottom 332. This can improve the stability of the cooperation between the first inclined surface 33 and the second inclined surface 511, and improve the stability of the locking of the locking portion 60 and the mop rod 10.

[0140] Alternatively, the inclined bottom 332 of the first inclined surface 33 is further provided with a second limiting member. When the core body 31 retracts into the through hole 201, the second limiting member can limit the movement of the driving member 51 to prevent the driving member 51 from excessively moving and moving to the inclined top 331, which can improve the stability of the cooperation between the first inclined surface 33 and the second inclined surface 511, and improve the stability of unlocking the to-be-locked portion 60 and the mop rod 10; alternatively, the inclined top 331 of the first inclined surface 33 and the inclined bottom 332 of the first inclined surface 33 can be respectively provided with a first limiting member 3311, which can improve the limiting effect on the driving member 51 and improve the stability of unlocking or locking the to-be-locked portion 60 and the mop rod 10.

[0141] Furthermore, the oblique top of the second inclined surface 511 may be provided with a third limiting member, or the oblique bottom of the second inclined surface 511 may be provided with a third limiting member, or the oblique top of the second inclined surface 511 and the oblique bottom of the second inclined surface 511 may be provided with third limiting members respectively; the third limiting member may cooperate with the first limiting member 3311, and the third limiting member may cooperate with the second limiting member, so as to realize the limiting of the driving member 51 and improve the limiting effect of the driving member 51.

[0142] It can be understood that the first limiting member 3311 and the second limiting member can be grooves, and the third limiting member can be a protrusion, and the protrusion can be plugged into and matched with the groove to achieve the limitation of the driving member 51; or, the first limiting member 3311 and the second limiting member can be protrusions, and the third limiting member can be a groove.

[0143] like Figure 4 and Figure 5As shown, in some examples, the lock core 30 is provided with a first limiting portion 321, and the mounting structure 20 is provided with a second limiting portion 22, so that the core 31 extends out of the through hole 201 (such as Figure 5 The direction from front to back as shown in the figure is the first direction, the first limiting portion 321 corresponds to the second limiting portion 22 one by one, and the first limiting portion 321 can be limited on the second limiting portion 22 to limit the lock core 30 in the first direction (such as Figure 4 activities in the up and down directions shown).

[0144] like Figure 4 and Figure 5 As shown, in some examples, the number of the first limiting portions 321 is set to at least two. When the number of the first limiting portions 321 is set to more than two, each first limiting portion 321 is evenly arranged around the outer circumference of the lock core 30, which can improve the limiting effect on the lock core 30; or, the first limiting portion 321 is an annular limiting portion, which extends around the circumference of the lock core 30, which is easy to process based on the fact that the limiting effect on the lock core 30 can be improved.

[0145] like Figure 4 and Figure 5 As shown, in some examples, the first limiting portion 321 can be a limiting block, and the second limiting portion 22 can be a limiting groove. The limiting groove can be plugged into and matched with the limiting block to limit the lock cylinder 30 and prevent the lock cylinder 30 from rotating together with the operating member 50, thereby improving the reliability of locking or unlocking the portion to be locked 60 and the mop rod 10.

[0146] like Figure 4 , Figure 5 and Figure 7 As shown, in some examples, the lock core 30 also includes a movable part 32, the core body 31 can be arranged on the movable part 32, and the elastic arm 40 can be connected to the movable part 32, that is, the elastic arm 40 can be arranged on the movable part 32 of the lock core 30; or, the elastic arm 40 can abut against the movable part 32, that is, the elastic arm 40 can be arranged on the mounting structure 20; thus, the movable part 32 is used to receive the driving force of the driving member 51 to drive the core body 31 to extend out of the through hole 201, and the movable part 32 is used to receive the restoring force of the elastic arm 40 to drive the core body 31 to retract into the through hole 201.

[0147] like Figure 6 and Figure 7As shown, in some examples, a mounting groove is provided on the movable part 32, and the core body 31 is provided in the mounting groove. The core body 31 can be interference fit with the mounting groove to facilitate disassembly and assembly; or, the core body 31 can be snap-fitted with the movable part 32 to facilitate operation; or, the movable part 32 can be fixedly connected to the core body 31, that is, the movable part 32 can be connected to the core body 31 by fasteners, and the fasteners can be screws or bolts, etc., which can improve the connection effect between the movable part 32 and the core body 31.

[0148] like Figure 6 As shown, in some examples, a locking surface 311 is provided on the core 31, and the locking surface 311 faces the mop rod 10. The shape of the locking surface 311 is adapted to the outer surface of the mop rod 10, which can increase the contact area between the core 31 and the mop rod 10, so that the operating member 50 can rotate relative to the mounting structure 20 to drive the core 31 to extend out of the through hole 201, so that the core 31 moves toward the direction close to the mop plate 80 (such as Figure 6 The locking surface 311 of the core body 31 presses against the mop rod 10, thereby increasing the friction between the core body 31 and the mop rod 10, improving the locking effect of the to-be-locked portion 60 and the mop rod 10, and preventing the to-be-locked portion 60 from moving along the extension direction of the mop rod 10 (as shown in the figure). Figure 1 up and down directions) as shown.

[0149] like Figure 4 and Figure 8 As shown, in some examples, a first clamping structure 23 is provided on the mounting structure 20, and a second clamping structure 521 is provided on the operating member 50. The first clamping structure 23 is used to clamp with the second clamping structure 521, so as to limit the operating member 50. On the basis of ensuring the normal rotation of the operating member 50, the operating member 50 can be prevented from being separated from the mounting structure 20, thereby improving the connection effect between the operating member 50 and the mounting structure 20.

[0150] like Figure 2 , Figure 4 and Figure 8 As shown, in some examples, the operating member 50 includes an operating ring 52, and the second clip structure 521 can be arranged on the inner wall of the operating ring 52, that is, the operating ring 52 can cover the first clip structure 23 and the second clip structure 521. On the one hand, the internal space of the operating member 50 can be fully utilized to save space. On the other hand, the first clip structure 23 and the second clip structure 521 can be hidden to prevent the first clip structure 23 and the second clip structure 521 from protruding from the surface arrangement of the operating member 50, which can improve the aesthetics of the mop 100.

[0151] like Figure 4 and Figure 8As shown, in some examples, a protrusion is provided on the inner circumferential wall of the operating ring 52, and the protrusion forms a second clamping structure 521. The first clamping structure 23 includes a hook, and the hook can be clamped with the protrusion to achieve the limitation of the operating member 50; the number of the protrusions is set to at least two, and at least two protrusions are arranged in sequence on the inner circumferential wall of the operating ring 52, and the hook and the protrusion are arranged one by one, which can improve the limiting effect of the operating member 50.

[0152] Alternatively, the protrusion includes an annular protrusion, which extends around the inner circumferential wall of the operating ring 52, so that the hook is always in contact with the annular protrusion during the rotation of the operating member 50, which is beneficial to improving the smoothness of the rotation of the operating member 50; the number of hooks is set to at least one, and when the number of hooks is more than two, each hook is evenly arranged in the circumferential direction of the annular protrusion, which can increase the contact area between the first clamping structure 23 and the second clamping structure 521, and can improve the stability of the rotation of the operating member 50.

[0153] like Figure 8 and Fig. 9 As shown, in some examples, a mounting portion 53 and a connecting member 54 are provided on the inner circumferential side of the operating ring 52. The connecting member 54 connects the outer circumferential wall of the mounting portion 53 and the inner circumferential wall of the operating ring 52 to achieve the connection between the mounting portion 53 and the operating member 50. The number of connecting members 54 is set to at least one. When the number of connecting members 54 is set to more than two, more than two connecting members 54 are arranged in sequence around the circumference of the mounting portion 53, which can improve the structural strength of the connection between the mounting portion 53 and the operating member 50, and the second inclined surface 511 can be provided on the mounting portion 53. Therefore, by rotating the operating ring 52, the entire operating member 50 can be driven to rotate, so as to drive the lock core 30 to move through the mounting portion 53, so as to achieve locking or unlocking of the to-be-locked portion 60 and the mop rod 10.

[0154] like Figure 4 and Figure 8 As shown, in some examples, a circumferential limiting mechanism is further provided on the operating member 50. When the operating member 50 is in the locked position, the core 31 extends out of the through hole 201. When the operating member 50 is in the unlocked position, the core 31 retracts into the through hole 201. The operating member 50 can rotate between the unlocked position and the locked position. The circumferential limiting mechanism is used to limit the operating member 50 between the unlocked position and the locked position, which can prevent the core 31 from retracting into the through hole 201 due to excessive rotation of the operating member 50 in the locked position, and can prevent the core 31 from extending out of the through hole 201 due to excessive rotation of the operating member 50 in the unlocked position, thereby improving the stability of locking or unlocking the to-be-locked portion 60 and the mop rod 10.

[0155] like Figure 4 and Figure 8As shown, in some examples, when a first clamping structure 23 is provided on the mounting structure 20, the circumferential limiting mechanism can cooperate with the first clamping structure 23 to limit the circumferential movement of the operating member 50 relative to the mounting structure 20, wherein, when the operating member 50 is in the locked position, the circumferential limiting mechanism can contact with one first clamping structure 23 to prevent the core body 31 from retracting into the through hole 201 due to excessive rotation of the operating member 50 in the locked position; when the operating member 50 is in the unlocked position, the circumferential limiting mechanism can contact with another first clamping structure 23 to prevent the core body 31 from extending out of the through hole 201 due to excessive rotation of the operating member 50 in the unlocked position, thereby limiting the operating member 50 between the unlocked position and the locked position, and improving the stability of locking or unlocking the to-be-locked portion 60 and the mop rod 10.

[0156] like Figure 4 and Figure 8 As shown, in some examples, when a connecting member 54 is further provided on the operating member 50, the connecting member 54 can form a circumferential limiting mechanism, and the first clamping structure 23 and the connecting member 54 are arranged at intervals, which can reserve sufficient rotation space for the operating member 50, wherein, when the operating member 50 is in the locked position, the connecting member 54 can contact with one first clamping structure 23 to prevent the core body 31 from retracting into the through hole 201 due to excessive rotation of the operating member 50 in the locked position; when the operating member 50 is in the unlocked position, the connecting member 54 can contact with another first clamping structure 23 to prevent the core body 31 from extending out of the through hole 201 due to excessive rotation of the operating member 50 in the unlocked position, thereby limiting the operating member 50 between the unlocked position and the locked position, and improving the stability of locking or unlocking the to-be-locked portion 60 and the mop rod 10.

[0157] like Figure 8-Figure 13 As shown, in some examples, the operating member 50 also includes a cover body 55, which can be covered outside the operating ring 52 to cover the components in the mounting structure 20, so as to hide the components in the mounting structure 20 and improve the aesthetics of the mop 100; of course, a mark (for example, a turn mark) can be provided on the cover body 55 to facilitate user operation.

[0158] like Fig.10 and Fig.13 As shown, in some examples, the cover body 55 can be installed on the mounting portion 53, and the cover body 55 can cover the inner circumference of the operating ring 52. The cover body 55 and the mounting portion 53 can be connected through a plug-in structure 553.

[0160] The circumferential limiting portion is used to limit the relative movement of the cover body 55 and the mounting portion 53 in the circumferential direction, which can ensure that the rotation of the operating member 50 can drive the cover body 55 to rotate together, and an identification can be provided on the cover body 55, thereby improving the consistency of the identification and the movement of the operating member 50, so as to ensure that the position information of the operating member 50 at different positions matches the identification information, which can improve the accuracy of the user's operation.

[0161] In some examples, the axial limiting portion includes a first limiting surface and a second limiting surface, and the mounting portion 53 is limited between the first limiting surface and the second limiting surface. Fig.10 As shown, the first limiting surface can be located at the front side of the mounting portion 53 (such as Fig.10 The second limiting surface may be located at the rear side of the mounting portion 53 (as shown in FIG. Fig.10 The rear side as shown), and the mounting portion 53 can be in contact with the first limiting surface and the second limiting surface respectively to limit the cover body 55, thereby preventing the cover body 55 from being separated from the mounting portion 53.

Figure 4The axial extension portion 552 extends in the front-to-back direction as shown, which is beneficial for the axial extension portion 552 to extend into the operating member 50, thereby facilitating the main body 551 to cooperate with the mounting portion 53 through the axial extension portion 552, and facilitating improving the connection effect between the cover body 55 and the mounting portion 53.

[0164] In some examples, when an axial limiting portion and a circumferential limiting portion are provided on the cover body 55, and the axial limiting portion includes a first limiting surface and a second limiting surface, the first limiting surface can be provided on the main body 551, and the second limiting surface can be provided on the axial extension portion 552, which can simplify the structure and improve the reliability of the cooperation between the axial limiting portion and the mounting portion 53; or, the first limiting surface can be provided on the axial extension portion 552, and the second limiting surface can be provided on the axial extension portion 552, which facilitates the cooperation between the axial limiting portion and the mounting portion 53.

[0166] like Figure 3 , Figure 8 and Fig.12 As shown, in some examples, the mop 100 also includes a radial limiting mechanism, which is used to limit the relative movement of the cover body 55 and the operating ring 52 in the radial direction. On the basis of ensuring that the operating ring 52 rotates together with the cover body 55, the stability of the rotation of the operating member 50 can be improved to prevent the cover body 55 from separating from the operating ring 52.

[0167] like Figure 3 , Figure 8 and Fig.12 As shown, in some examples, the main body 551 can be installed on the inner circumferential side of the operating ring 52, the radial limiting mechanism includes the inner circumferential wall of the operating ring 52, and the main body 551 can be interference fit with the inner circumferential wall of the operating ring 52 to facilitate disassembly and assembly; or, the radial limiting mechanism includes a first clamping structure 23 and a mounting portion 53, the first clamping structure 23 is located on the outer circumferential side of the mounting portion 53, and the axial extension portion 552 can be limited between the first clamping structure 23 and the mounting portion 53. On the basis of ensuring that the cover body 55 is connected to the mounting portion 53, the internal space of the operating member 50 can be fully utilized, and operation is convenient.

[0168] like Figure 4 , Figure 8 and Fig.14As shown, in some examples, a torsion spring 90 is abutted between the operating member 50 and the lock core 30, one end of the torsion spring 90 can be connected to the mounting structure 20, and the other end of the torsion spring 90 can be connected to the mounting portion 53, so that the torsion spring 90 can be elastically deformed during the rotation of the operating member 50 to the locked position, that is, the torsion spring 90 can be elastically deformed when the core 31 extends out of the through hole 201, so that the torsion spring 90 can restore its original shape after deformation to drive the operating member 50 to rotate to the unlocked position, and the core 31 can be retracted into the through hole 201, which can improve the smoothness of unlocking the to-be-locked portion 60 and the mop rod 10.

[0169] It is understandable that the user can drive the operating member 50 to rotate after the locking portion 60 and the mop rod 10 are locked to unlock the locking portion 60 and the mop rod 10, so that the torsion spring 90 can apply a force to the mounting portion 53 of the operating member 50 when the locking portion 60 and the mop rod 10 are unlocked, so that the locking portion 60 and the mop rod 10 are quickly unlocked for easy operation.
