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. A mop cloth is attached to a mop head, and the mop handle is held by hand to clean the floor. Most commercially available mops employ a fixed mop cloth, but replacing the mop cloth is relatively complicated. The mop cloth is usually used for a long time and will become dirty and unclean after being used multiple times. 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 is easy to replace the mop cloth. Its handle includes an outer sleeve connected to the mop bottom plate and an inner shaft slidably connected 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 a drive assembly via 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 relative reverse rotation of the screw rod is interlocked. By interlocking the relative reverse rotation of the gears via the connecting member, the second clamp approaches the first clamp, and both of them clamp 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 also complex. Moreover, since the twist rod is provided inside the handle, the possibility of problems such as snagging 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 before.

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 side or both sides of the main clamp. A cross-clamping assembly, a slide base provided in the mop head and attached to slide vertically therein, 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. Mop head and a drive assembly including 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] Further, 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 so that 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, so that the pull rod presses the movable clamp against the main clamp to clamp the cross.

[0012] Further, 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] Further, 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 regulate the upward sliding of the pressing protrusions, thereby holding the cross-clamping assembly in a clamped state.

[0015] In addition, 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] In addition, 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 extension portion is provided inwardly at one end of the movable clamp, a restricting concave groove is provided on the extension portion, and the spring is arranged in the restricting concave groove.

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

Advantages of the Invention

[0022] According to the cross-clamping mop of the present invention, it has a simpler structure than before and becomes a mop with easy attachment and detachment of the cross.

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

[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 attached 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 attached to 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 attached in the vertical direction on the mop head 1 and a pull rod 42 with 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 protrusion 411 is provided on the slide base 41, and the pressing protrusion 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 them, a first pivoting base 422 is symmetrically provided at one end of the pull rod 42, a second pivoting base 321 is symmetrically provided at one end of the movable clamp 32, one end of the link 43 is pivoted between two first pivoting bases 422, and the other end is pivoted between two second pivoting bases 321.

[0039] In some embodiments, as shown in FIGS. 4 and 5, 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 locations, so the cross-clamping effect is further improved.

[0040] Also, a spring 33 is mounted between the two movable clamps 32, and the spring 33 biases the movable clamp 32 in a direction away from the main clamp 31. Among them, an extending portion 322 is provided inwardly at one end of the movable clamp 32, a restricting concave groove 323 is provided on the extending portion 322, and the spring 33 is disposed within the restricting concave 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, by way of example, has an inclined surface with a gradually increasing height from top to bottom, and a substantially triangular shape is formed in the vertical cross-section. 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 thereof 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 protrusion 421 to restrict the pressing protrusion 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 thus the cross-clamping assembly 3 is held in the 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 protrusion 411 exceeds the restricting force of the positioning protrusion 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 protrusions 411 are symmetrically provided, and between the two pressing protrusions 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 protrusions 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 an 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 tooth portion 311 is provided at the side end of the main clamp 31. A second tooth portion 324 that can mesh with the first tooth portion 311 is provided on the movable clamp 32. By sandwiching the mop cross through the combination of the first tooth portion 311 and the second tooth 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 usage process of the cross-clamping type mop of 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, the inner shaft 22 should be pulled 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 and moves the pull rod 42 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] The specific embodiments of the present invention have been illustrated above. For the same or similar parts among the embodiments in this specification, reference may be made to each other. Those described with emphasis in each embodiment are different from other embodiments.

[0056] In addition, the above is merely a specific embodiment 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 in the protection scope of the present invention.
