Description

Technical Field

[0001] The present invention relates to a cross-clamping type mop that uses a mop cloth by replacing it, and particularly to a cross-clamping type mop that is easy to replace the mop cloth.

Background Art

[0002] Mops are often used for cleaning the floor surface. A mop cloth is attached to the mop head, and the handle of the mop is held by hand to clean the floor surface. Most commercially available mops adopt a fixed mop cloth, but the replacement of the mop cloth is relatively complicated. The mop cloth is usually used for a long time, and after being used multiple times, dirt accumulates and it becomes dirty. To solve this problem, the following cross-clamping type mop with a replaceable mop cloth has been designed.

[0003] For example, Patent Document 1 discloses a cross-clamping type mop that makes it easy to replace the mop cloth. Its handle includes an outer sleeve connected to the mop bottom plate and an inner shaft connected to slide inside the outer sleeve. A screw rod (twist rod) is provided inside the inner shaft, and at least a part of the inner wall of the inner shaft engages with each other.

[0004] Among them, the screw rod is connected to the drive assembly through a connecting member. When clamping, the inner shaft is pushed downward. Since the inner wall of the inner shaft engages with the screw rod, the screw rod rotates relatively in the opposite direction in conjunction with it. By interlocking the relative opposite rotation of the gears through the connecting member, the second clamp approaches the first clamp, and the two clamp the mop cloth to clamp the mop cloth.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the structure of Patent Document 1, a drive structure that combines a drive gear with a twist rod is adopted. There are many drive parts and the drive process is complex. Moreover, since the twist rod is provided inside the handle, the possibility of problems such as getting caught due to the combination of the twist rod and the gear increases, and the weight of the handle tends to increase, requiring labor when mopping the floor.

[0007] The problem to be solved by the present invention is to provide a cross-clamping type mop with a simpler structure than conventional ones.

Means for Solving the Problems

[0008] To solve the above problems, a cross-clamping type mop according to one aspect of the present invention is a cross-clamping type mop that exchanges a mop cloth for use, and includes a mop head, an outer sleeve attached to the upper end of the mop head and pivotally connected to the mop head, a handle including an inner shaft slidably attached inside the outer sleeve, a main clamp disposed at the bottom of the mop head and fixed to the mop head, and a movable clamp provided to slide horizontally on one or both sides of the main clamp. A cross-clamping assembly, a slide base provided in the mop head and slidably attached to the mop head in the vertical direction, and a pull rod having one end pivotally connected to the mop head. The slide base is connected to drive the inner shaft, and the other end of the pull rod is pivotally connected to the movable clamp directly or indirectly. A drive assembly, wherein the movable clamp slides in the opening and closing directions with respect to the main clamp via the drive assembly in response to the operation of the inner shaft.

[0009] According to this configuration, by using the driving method of the slide base and the pull rod instead of the conventional driving method of the gear and the twist rod, while having a simple structure, by sliding the inner shaft, the movable clamp moves, and the attachment and detachment of the cross becomes easy. Thereby, the risk of defects can be suppressed more than before, and the weight can also be reduced.

[0010] In addition, in this cross-clamping type mop, a pressing projection is provided on the slide base, and the pressing projection is arranged to abut on the side wall of the pull rod. When clamping the cross, the inner shaft is pressed downward to slide the slide base downward, and the pressing projection swings the pull rod, and the pull rod drives the movable clamp to approach the main clamp.

[0011] According to this configuration, when the inner shaft is pressed downward, the inner shaft slides the slide base downward, the slide base slides the pressing projection downward, and the pressing projection swings the pull rod inward. Therefore, the pull rod presses the movable clamp against the main clamp to clamp the cross.

[0012] In addition, in this cross-clamping type mop, the pull rod is pivotally connected to the movable clamp via a link, one end of the link is pivotally connected to the pull rod, and the other end is pivotally connected to the movable clamp.

[0013] In addition, in this cross-clamping type mop, the movable clamp is attached so as to slide on either side of the main clamp, a spring is attached between the two movable clamps, and the spring biases the movable clamp in a direction away from the main clamp.

[0014] In addition, in this cross-clamping mop, positioning protrusions are provided on the side wall of the pull rod, and the positioning protrusions hold the cross-clamping assembly in a clamped state by restricting the upward sliding of the pressing protrusions.

[0015] Further, this cross-clamping mop has an inclined surface such that the height of the positioning protrusion gradually increases from top to bottom. When the pressing protrusion moves from top to bottom, it slides downward along the inclined surface of the positioning protrusion, and when the pressing protrusion exceeds the inclined surface, its upward sliding is restricted by the positioning protrusion.

[0016] In addition, this cross-clamping mop has two movable clamps. Protrusion bases are symmetrically provided on both sides of the slide base, and pressing protrusions are symmetrically provided on the protrusion bases. The pull rod is symmetrically attached between the two pressing protrusions. Corresponding ends of the two pull rods are pivotally connected to the mop head, and the other ends are connected to the corresponding movable clamps.

[0017] Further, in this cross-clamping mop, the slide base is connected to the inner shaft via an inner connection base. One end of the inner connection base is pivotally connected to the slide base, and the other end is pivotally connected to the inner shaft.

[0018] In addition, in this cross-clamping mop, the outer sleeve is connected to the mop head via an outer connection base. One end of the outer connection base is pivotally connected to the outer sleeve, and the other end is pivotally connected to the mop head. The inner connection base is located inside the outer connection base.

[0019] In addition, for this cross-clamping mop, a first pivot base is symmetrically provided at one end of the pull rod, a second pivot base is symmetrically provided at one end of the movable clamp, one end of the link is pivotally connected between two first pivot bases, and the other end is pivotally connected between two second pivot bases.

[0020] In addition, for this cross-clamping mop, an extending portion is provided inwardly at one end of the movable clamp, a restricting concave groove is provided on the extending portion, and the spring is disposed within the restricting concave groove.

[0021] In addition, for this cross-clamping mop, a first toothed portion is provided at the side end of the main clamp, and a second toothed portion engageable with the first toothed portion is provided on the movable clamp.

FIG. 9 is a perspective view of the mop head and the movable clamp of the cross-clamping mop according to an embodiment of the present invention connected.

[0032] Refer to FIGS. 1 to 9. The cross-clamping type mop according to an embodiment of the present invention mainly includes a mop head 1, a handle 2, a cross-clamping assembly 3, and a drive assembly 4.

[0033] Refer to FIGS. 3 and 4. The handle 2 is attached to the upper end of the mop head 1. The handle 2 includes an outer sleeve 21 pivotally connected to the mop head 1 and an inner shaft 22 slidably mounted within the outer sleeve 21. The cross-clamping assembly 3 is attached to the bottom of the mop head 1 and is used to clamp the mop cross. A thin non-woven fabric can be adopted for the mop cross.

[0034] The cross-clamping assembly 3 includes a main clamp 31 fixed to the mop head 1 and a movable clamp 32 slidably mounted on one or both sides of the main clamp 31.

[0035] The drive assembly 4 is provided within the mop head 1 and is used to drive the cross-clamping assembly 3 to clamp or release. The drive assembly 4 includes a slide base 41 slidably mounted vertically on the mop head 1 and a pull rod 42 having one end pivotally connected to the mop head 1.

[0036] The slide base 41 is connected to drive the inner shaft 22, and the other end of the pull rod 42 is pivotally connected to the movable clamp 32 directly or indirectly. A pressing projection 411 is provided on the slide base 41, and the pressing projection 411 is arranged to abut against the side wall of the pull rod 42.

[0037] In some embodiments, as shown in FIGS. 4 and 5, for convenience of connection and drive, the pull rod 42 is pivotally connected to the movable clamp 32 via a link 43. One end of the link 43 is pivotally connected to the pull rod 42, and the other end is pivotally connected to the movable clamp 32.

[0038] Among these, a first pivot base 422 is symmetrically provided at one end of the pull rod 42, a second pivot base 321 is symmetrically provided at one end of the movable clamp 32, one end of the link 43 is pivotally connected between two first pivot bases 422, and the other end is pivotally connected between two second pivot bases 321.

[0039] In some embodiments, as shown in FIGS. 4 and 5, the movable clamps 32 are mounted on both sides of the main clamp 31 so as to slide. By adopting two movable clamps 32, the cross is clamped at two places, so the cross-clamping effect is further improved.

[0040] Also, a spring 33 is attached between the two movable clamps 32, and the spring 33 biases the movable clamps 32 in a direction away from the main clamp 31. Among these, an extension portion 322 is provided inwardly at one end of the movable clamp 32, a restricting groove 323 is provided on the extension portion 322, and the spring 33 is disposed within the restricting groove 323.

[0041] In a preferred embodiment, as shown in FIGS. 5 and 6, a positioning protrusion 421 is provided on the side wall of the pull rod 42. The positioning protrusion 421 can hold the cross-clamping assembly 3 in a clamped state by restricting the upward sliding of the pressing protrusion 411.

[0042] Specifically, the positioning protrusion 421 of this embodiment has, as an example, an inclined surface with a gradually increasing height from top to bottom, and the vertical cross-section is formed in a substantially triangular shape. With this configuration, when the pressing protrusion 411 moves from top to bottom, it slides downward along the inclined surface of the positioning protrusion 421, and when the pressing protrusion 411 exceeds the inclined surface, the upward sliding is restricted by the positioning protrusion 421, so that the cross-clamping assembly 3 can be held in a clamped state.

[0043] In addition, since the spring 33 is attached, by providing the positioning projection 421 to restrict the pressing projection 411, it is necessary to ensure that after the external force pressing the inner shaft 22 downward disappears, the movable clamp 32 does not return to its original position, and ultimately the cross-clamping assembly 3 is held in a clamped state.

[0044] When it is desired to replace the mop cloth, the inner shaft 22 is pulled upward. After the upward force of the pressing projection 411 exceeds the restricting force of the positioning projection 421, under the action of the spring 33, the movable clamp 32 returns to its original position and the cross-clamping assembly 3 is released.

[0045] In some embodiments, as shown in FIGS. 4 and 5, there are two movable clamps 32. On both sides of the slide base 41, convex bases 412 are symmetrically provided. On the convex bases 412, pressing projections 411 are symmetrically provided, and between the two pressing projections 411, pull rods 42 are symmetrically attached.

[0046] The corresponding one ends of the two pull rods 42 are pivotally connected to the mop head 1, and the other ends are connected to the corresponding movable clamps 32. That is, the number of slide bases 41 is one, the number of pressing projections 411 is four, and the number of corresponding pull rods 42 and links 43 is four. This structure is advantageous for ensuring structural stability, with stable driving and high reliability.

[0047] In some embodiments, as shown in FIGS. 3 and 8, the slide base 41 is connected to the inner shaft 22 via the inner connection base 23. One end of the inner connection base 23 is pivotally connected to the slide base 41, and the other end is pivotally connected to the inner shaft 22.

[0048] The outer sleeve 21 is connected to the mop head 1 via the outer connection base 24. One end of the outer connection base 24 is pivotally connected to the outer sleeve 21, and the other end is pivotally connected to the mop head 1. The inner connection base 23 is located within the outer connection base 24.

[0049] In some embodiments, as shown in FIGS. 2, 3, and 7, a first toothed portion 311 is provided at the side end of the main clamp 31. A second toothed portion 324 that can mesh with the first toothed portion 311 is provided on the movable clamp 32. By sandwiching the mop cross through the combination of the first toothed portion 311 and the second toothed portion 324, the clamping effect is further improved.

[0050] In some embodiments, as shown in FIG. 9, a connection portion 325 is provided inside the movable clamp 32. On one or both sides where the connection portion 325 and the extending portion 322 are located on the inner wall of the mop head 1, a regulating tooth 101 is provided. In this way, the regulating tooth 101 regulates and guides the connection portion 325 and the extending portion 322, so that the sliding stability of the movable clamp 32 on the mop head 1 is improved.

[0051] The use process of the cross-clamping type mop in this embodiment is as follows.

[0052] First, when clamping the cross, lay the mop cross flat on the ground, and then place the mop head 1 on the mop cross. At this time, if the movable clamp 32 is in a closed state close to the main clamp 31, pull the inner shaft 22 upward relative to the outer sleeve 21 in advance to make the movable clamp 32 in an open state separated from the main clamp 31.

[0053] Next, press the inner shaft 22 downward, causing the inner shaft 22 to slide the slide base 41 downward, and the slide base 41 to slide the pressing projection 411 downward. Then, the pressing projection 411 presses the pull rod 42 to swing inward, and the pull rod 42 drives the movable clamp 32 to approach the main clamp 31 via the link 43, so that the mop cloth is clamped. The mop can be used in this state.

[0054] Also, when the use of the mop is finished, pull the inner shaft 22 upward with respect to the outer sleeve 21 to make the movable clamp 32 in an open state separated from the main clamp 31, and remove the mop cloth from the mop head 1. At this time, if you hold the mop head above the trash can and remove the mop cloth, you can throw it away in the trash can without touching the mop cloth, which is hygienic.

[0055] As mentioned above, specific embodiments of the present invention have been illustrated. However, for the same or similar parts among the respective embodiments in this specification, reference may be made to each other. Those parts that are emphasized and described in each embodiment are all different from other embodiments.

[0056] Also, the above are merely specific embodiments of the present invention, and the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all included within the protection scope of the present invention.
