Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a sleeve type water wringing mop. Background Art

[0002] At present, the water wringing method of the foamed cotton mop on the market mainly adopts the folding water wringing type. The water wringing mop mainly includes a mop rod and a folding type mop head with foamed cotton. A water wringing frame capable of sliding up and down along the mop rod is arranged on the mop rod. The water wringing frame is often a sleeve with a through hole. An extrusion component for extruding the mop head passing through the through hole is arranged in the sleeve, so as to complete the water wringing action of the mop. However, there is a risk that the mop rod may slide out when the water wringing frame slides up and down relative to the mop rod. Therefore, as shown in the Chinese utility model "A folding water wringing type foamed cotton mop" with the patent number CN201922485404.5 (the authorized publication number is CN212307746U), a positioning structure is arranged between the water wringing frame and the mop rod. The positioning structure includes a positioning block fixed on the mop rod and an elastic clamping groove arranged in the water wringing frame. When the positioning block is clamped into the elastic clamping groove, the water wringing frame can be positioned in the upward movement position state. After the positioning block disengages from the elastic clamping groove to release the positioning, the water wringing frame can move up and down along the mop rod. And in order to enable the positioning block to be smoothly clamped into or disengaged from the elastic clamping groove, a guiding groove located above the elastic clamping groove and communicated with the elastic clamping groove is also arranged on the inner wall of the water wringing frame. The positioning block can slide up and down along the guiding groove. The cooperation between the positioning block and the elastic clamping groove can position the water wringing frame in the upward movement position, not easily move downward, and will not affect mopping the floor. After the positioning is released, the water wringing frame can be moved to realize water wringing of the folding type mop head.

[0003] Although the above-mentioned sleeve type water wringing mop can wring water from the mop head, some components of the positioning mechanism in this water wringing mop are arranged on the inner wall of the water wringing frame, and the structure is relatively complex, making it difficult to assemble the positioning mechanism. And the cooperation between the positioning block and the guiding groove in this positioning mechanism will prevent the water wringing frame from rotating around the axis of the mop rod. However, during the actual use by the user, there will be a situation where the water wringing frame is accidentally rotated, resulting in the positioning block disengaging from the guiding groove, and the user cannot install the water wringing frame and the mop rod, so that the water wringing frame cannot extrude the mop head. Moreover, because the guiding groove must have a certain length to meet the guiding function of up and down sliding, the length of the water wringing frame must be made long, making the volume of the water wringing frame large, which is not conducive to the miniaturization of the product, and it is also very inconvenient to form and process the long and thin guiding groove.

[0004] Therefore, further improvement needs to be made to the sleeve type water wringing mop. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a sleeve type water wringing mop with reasonable structure, capable of rotating relative to the mop rod during the up and down movement of the water wringing frame and locking after moving up in place according to the above-mentioned current situation of the prior art.

[0006] The technical solution adopted by the present utility model to solve the above technical problems is as follows: The sleeve-type water-squeezing mop includes a mop rod, a foldable mop head, and a water-squeezing frame. The foldable mop head is movably connected to the lower end of the mop rod. The water-squeezing frame is sleeved on the mop rod in a sleeve shape and can slide up and down. A locking structure is provided between the mop rod and the water-squeezing frame. It is characterized in that the water-squeezing frame can rotate 360 degrees around its own axis, and after rotating the water-squeezing frame at any angle and then moving it upward, it can be locked on the mop rod through the locking structure.

[0007] As a preferred embodiment of the locking structure, the locking structure includes an annular rib and an elastic clamping foot. One of the annular rib and the elastic clamping foot is provided on the mop rod, and the other is provided on the water-squeezing frame. The elastic clamping foot after moving upward can clamp the annular rib, and the locking and unlocking of the water-squeezing frame and the mop rod are realized through the clamping of the annular rib and the elastic clamping foot. After unlocking, the water-squeezing frame can rotate 360 degrees around its own axis. The annular rib ensures that after the water-squeezing frame rotates at any angle and then moves upward, the elastic clamping foot can be stuck on the annular rib.

[0008] As an improvement, an outwardly protruding clamping rib is provided on the inner wall of the above-mentioned elastic clamping foot, and the clamping rib is stuck above the annular rib, so that the clamping of the elastic clamping foot and the annular rib is relatively firm; in order to facilitate the annular rib to cross the clamping rib and form a stuck state, the top surface and the bottom surface of the clamping rib are both inclined surfaces.

[0009] To further make the clamping of the elastic clamping foot and the annular rib relatively firm, a clamping groove for the annular rib to be inserted into is further provided on the inner wall of the above-mentioned elastic clamping foot, and the clamping groove is provided below the clamping rib.

[0010] To facilitate the setting of the annular rib, as a further improvement, an annular positioning member is sleeved and fixed on the above-mentioned mop rod, the annular rib is provided on the outer peripheral wall of the annular positioning member, and the elastic clamping foot is provided on the inner hole wall of the water-squeezing frame. The annular positioning member can be independently manufactured, and the annular rib can be directly formed. During assembly, only the annular positioning member needs to be fixedly installed on the mop rod, and the annular rib is formed on the mop rod. Of course, the annular rib can also be directly formed on the mop rod.

[0011] In order to make the water-squeezing frame unable to rotate after being locked with the mop rod, preferably, the lower end of the above-mentioned annular positioning member extends downward to form a plurality of serrated protrusions, and a positioning groove corresponding to the protrusions is provided on the inner hole wall of the water-squeezing frame. In the state where the annular rib and the elastic clamping foot are clamped with each other, the protrusions and the positioning grooves are engaged with each other to form a circumferential constraint. The protrusions and the positioning grooves are engaged with each other, so that the water-squeezing frame and the mop rod cannot rotate relative to each other in the locked state. Of course, if there is no such structure as mentioned above, in the locked state, the water-squeezing frame can also rotate 360 degrees around its own axis relative to the mop rod.

[0012] To achieve the fixed connection between the annular positioning member and the mop rod, preferably, the annular positioning member and the mop rod are fixedly connected through a connecting shaft, and the connecting shaft can pass through the annular positioning member and the mop rod to achieve the fixed connection. The connecting shaft passes through the through holes on the annular positioning member and the mop rod, thereby fixedly connecting the annular positioning member and the mop rod.

[0013] To facilitate the assembly of the water wringing frame, preferably, the water wringing frame is divided into an upper cylinder body and a lower cylinder body that are threadedly connected together, and the elastic clamping feet are arranged inside the lower cylinder body. The elastic clamping feet are installed inside the lower cylinder body. The manufacturer can first assemble the mop rod with a ring-shaped rib inside the lower cylinder body. After the elastic clamping feet of the lower cylinder body clamp the ring-shaped rib, then tighten the upper cylinder body, so that the assembly of the sleeve-type water wringing mop is more convenient.

[0014] To prevent the threaded connection between the upper cylinder body and the lower cylinder body from loosening, preferably, a plurality of limiting grooves are provided along the circumferential direction at the lower end of the upper cylinder body, and an elastic check member is provided on the circumferential wall of the lower cylinder body. The check member includes a guiding surface and a check surface. The check surface extends along the radial direction of the lower cylinder body, and the included angle between the guiding surface and the check surface is an acute angle. The check member can be sequentially clamped into the limiting grooves through the guiding surface. When the upper cylinder body and the lower cylinder body are in a state of being screwed tightly, the check surface abuts against the groove wall of the limiting groove. Through the check member, when the upper cylinder body and the lower cylinder body are in a state of being screwed tightly, the upper cylinder body and the lower cylinder body can be interlocked and cannot rotate to become loose.

[0015] Furthermore, there are two check members, which are oppositely arranged on the circumferential wall of the lower cylinder body. The two opposite check portions make the interlocking effect between the upper cylinder body and the lower cylinder body better.

[0016] Compared with the prior art, the advantages of the present utility model are as follows: The locking structure includes a ring-shaped rib and elastic clamping feet. One of the ring-shaped rib and the elastic clamping feet is arranged on the mop rod, and the other is arranged on the water wringing frame. The elastic clamping feet after being moved upward can clamp the ring-shaped rib. Through the clamping and matching of the ring-shaped rib and the elastic clamping feet, the locking and unlocking of the water wringing frame and the mop rod are realized. After unlocking, the water wringing frame can rotate 360 degrees around its own axis; after the water wringing frame and the mop rod rotate relative to each other, the elastic clamping feet can still clamp inside the ring-shaped rib to realize the locking of the water wringing frame and the mop rod, thereby making the assembly of the water wringing frame and the mop rod more convenient, and further improving the use experience of the sleeve-type water wringing mop. In addition, there is no need to provide a traditional long strip-shaped guiding groove on the inner hole wall of the water wringing frame, so that the water wringing frame can be made shorter, which is beneficial to the miniaturization of the product.

[0017] As another preference of the locking structure, the above-mentioned locking structure includes an annular positioning groove and an elastic clamping foot. One of the annular positioning groove and the elastic clamping foot is arranged on the mop rod, and the other is arranged on the wringer. The elastic clamping foot after upward movement can be stuck in the annular positioning groove, and the locking and unlocking of the wringer and the mop rod are realized through the clamping of the annular positioning groove and the elastic clamping foot. After unlocking, the wringer can rotate 360 degrees around its own axis. After the wringer and the mop rod rotate relative to each other, the elastic clamping foot can still be stuck in the annular positioning groove to realize the locking of the wringer and the mop rod, so that the assembly of the wringer and the mop rod is more convenient, and further improves the use experience of the sleeve wringing mop. In addition, there is no need to set a traditional long strip-shaped guiding groove on the inner hole wall of the wringer, so that the wringer can be made short, which is beneficial to the miniaturization of the product.

[0018] For the convenience of setting the annular positioning groove, in a further improvement, an annular positioning member is sleeved and fixed on the above-mentioned mop rod, the annular positioning groove is arranged on the outer peripheral wall of the annular positioning member, and the elastic clamping foot is arranged on the inner hole wall of the wringer. The annular positioning member can be independently manufactured, and the annular positioning groove can be directly formed. During assembly, only need to fixedly install the annular positioning member on the mop rod, that is, an annular positioning groove is formed on the mop rod. Of course, the annular positioning groove can also be directly formed on the mop rod.

[0019] As yet another preference of the locking structure, the above-mentioned locking structure includes a damping sleeve fixed on the mop rod. When the wringer is moved upward to the mopping position, the damping sleeve abuts against the inner wall of the wringer to form damping. The locking structure uses the damping sleeve to realize the locking and unlocking of the wringer and the mop rod. After unlocking, the wringer can rotate 360 degrees around its own axis; after the wringer and the mop rod rotate relative to each other, the wringer is moved upward to the mopping position, and the damping sleeve can still abut against the inner wall of the wringer to form damping, realizing the locking of the wringer and the mop rod, so that the assembly of the wringer and the mop rod is more convenient.

[0028] As Figure 1 shown, the sleeve-type water wringing mop of this embodiment includes a mop rod 1, a foldable mop head 2, and a water wringing frame 3. The foldable mop head 2 is movably connected to the lower end of the mop rod 1. The water wringing frame 3 is sleeved on the mop rod 1 in a sleeve shape and can slide up and down. A locking structure is provided between the mop rod 1 and the water wringing frame 3. The water wringing frame 3 can rotate 360 degrees around its own axis. After the water wringing frame 3 rotates at any angle and then moves upward, it can be locked on the mop rod 1 through the locking structure.

[0029] As Figure 2 and Figure 3 shown, the locking structure in this embodiment includes an annular rib 41 and an elastic clamping foot 32. Among them, an annular positioning member 4 is sleeved and fixed on the mop rod 1. The annular positioning member 4 and the mop rod 1 are fixedly connected through a connecting shaft 5. The connecting shaft 5 can pass through the annular positioning member 4 and the mop rod 1 to achieve fixed connection. The annular rib 41 is provided on the outer peripheral wall of the annular positioning member 4, and the elastic clamping foot 32 is provided on the inner hole wall 31 of the water wringing frame 3. The elastic clamping foot 32 after moving upward can clamp the annular rib 41. The locking and unlocking of the water wringing frame 3 and the mop rod 1 are realized through the clamping of the annular rib 41 and the elastic clamping foot 32. After unlocking, the water wringing frame 3 can rotate 360 degrees around its own axis.

[0030] An outwardly protruding rib 321 is provided on the inner wall of the elastic clamping foot 32 in this embodiment. The top surface and the bottom surface of the rib 321 are both inclined surfaces. A clamping groove 322 for the annular rib 41 to be inserted into is also provided on the inner wall of the elastic clamping foot 32. The clamping groove 322 is provided below the rib 321, so that the clamping of the elastic clamping foot 32 and the annular rib 41 is relatively firm.

[0031] As Figure 3 and Figure 4 shown, a plurality of serrated protrusions 42 are formed by the lower end of the annular positioning member 4 in this embodiment extending downward. A positioning groove 311 corresponding to the protrusions 42 is provided on the inner hole wall 31 of the water wringing frame 3. In the state where the annular rib 41 and the elastic clamping foot 32 are clamped with each other, the protrusions 42 and the positioning groove 311 are engaged with each other to form a circumferential constraint.

[0032] As Figures 4 to 6As shown in the figure, the water wringer 3 is divided into an upper cylinder body 33 and a lower cylinder body 34 that are threadedly connected together, and the elastic clamping feet 32 are arranged inside the lower cylinder body 34. Among them, a plurality of limiting grooves 331 are provided along the circumferential direction at the lower end of the upper cylinder body 33, and an elastic check member 6 is provided on the circumferential wall of the lower cylinder body 34. There are two check members 6 and they are oppositely arranged on the circumferential wall of the lower cylinder body 34. The check member 6 includes a guiding surface 61 and a check surface 62. The check surface 62 extends along the radial direction of the lower cylinder body 34. The included angle between the guiding surface 61 and the check surface 62 is an acute angle. The check member 6 can be sequentially snapped into the limiting grooves 331 through the guiding surface 61. When the upper cylinder body 33 and the lower cylinder body 34 are in a state of being screwed tightly, the check surface 62 abuts against the groove wall of the limiting groove 331, so that the upper cylinder body 33 and the lower cylinder body 34 can be interlocked and cannot rotate and become loose.

[0033] The working process of this embodiment is as follows:

[0034] A. First, assemble the annular positioning member 4 fixedly connected to the mop rod 1 into the inner hole wall 31 of the lower cylinder body 34. The convex portion 42 and the positioning groove 311 are engaged with each other to form a circumferential constraint, and the clamping groove 322 of the elastic clamping foot 32 clamps the annular rib 41 to form an axial constraint, so that the water wringer 3 and the mop rod 1 are in a locked state. Then, tighten the upper cylinder body 33. The check member 6 of the lower cylinder body 34 is sequentially snapped into the limiting grooves 331 of the upper cylinder body 33 through the guiding surface 61. When the upper cylinder body 33 and the lower cylinder body 34 are in a state of being screwed tightly, the check surface 62 abuts against the groove wall of the limiting groove 331, and the assembly of the sleeve-type water wringing mop is completed;

[0035] B. When the user needs to wring the mop, hold the water wringer 3 with one hand and the mop rod 1 with the other hand, and push the water wringer 3 to move downward relative to the mop rod 1, so that the convex portion 42 on the annular positioning member 4 disengages from the positioning groove 311 and they do not contact each other. Moreover, the annular rib 41 disengages from the clamping groove 322 of the elastic clamping foot 32, and the water wringer 3 and the mop rod 1 are in an unlocked state. After unlocking, the water wringer 3 can rotate 360 degrees around its own axis, and the foldable mop head 2 can be folded into the inner cavity of the water wringer 3 under the action of the water wringer 3 for wringing water.
