Description

Technical fields:

[0001] This invention relates to an adjustment mechanism for a plywood mop. Background technology:

[0002] Currently, there are many types of PVA mops on the market. For example, a PVA mop includes a mop handle and a PVA head. The lower end of the mop handle has a clamping mechanism for squeezing water from the PVA head, and the clamping mechanism has a clamping opening. The PVA head is connected to the mop handle through a pulling mechanism. The pulling mechanism moves up and down relative to the mop handle to drive the PVA head into or out of the clamping opening. When wringing water, the pulling mechanism moves upward relative to the mop handle to drive the PVA head into the clamping opening for squeezing and dehydration. However, after long-term use, the PVA head of the PVA mop is prone to deformation and damage. The deformed and damaged PVA head is relatively loose relative to the clamping opening, making it easy to twist and damage when cleaning the ground. The PVA mop with the above structure has a PVA head that is prone to loosening, and the loosened PVA head has a short service life and poor cleaning effect. Summary of the Invention:

[0003] One objective of this invention is to provide an adjustment mechanism for a PVA mop that solves the aforementioned problems. To achieve this objective, the invention is implemented through the following technical solution: an adjustment mechanism for a PVA mop, the PVA mop comprising a mop handle and a PVA head, wherein the lower end of the mop handle is provided with a clamping mechanism for squeezing water from the PVA head, and the clamping mechanism has a clamping opening; the PVA head is connected to the mop handle via a pulling mechanism, the pulling mechanism moving up and down relative to the mop handle to drive the PVA head into or out of the clamping opening, and during dehydration, the pulling mechanism moving upward relative to the mop handle to drive the PVA head into the clamping opening for squeezing and dehydration; characterized in that: the clamping mechanism includes a movable adjustment mechanism, the adjustment mechanism moving within the clamping mechanism to change the limiting distance when the pulling mechanism moves downward relative to the clamping mechanism, thereby changing the limiting distance when the PVA head moves downward relative to the clamping opening.

[0004] In this invention, the clamping mechanism includes a clamping frame, the upper end of which is connected to the lower end of the mop handle. The lower end of the clamping frame has an opening, and pressure rollers are respectively provided on both sides of the opening, forming a clamping opening between the two pressure rollers. The pulling mechanism includes a pull rod and a driving member. One end of the pull rod is connected to the adhesive cotton head, and the other end passes through the clamping frame and is connected to the driving member located above. The driving member is movably connected to the mop handle. Movement of the driving member relative to the mop handle can drive the pull rod to move up and down relative to the clamping frame, thereby pulling the rod to drive the adhesive cotton head into or out of the clamping opening. The adjusting mechanism includes an adjusting seat, which is movably mounted on the clamping frame. Adjustment and movement of the adjusting seat within the clamping frame change the limiting distance of the pull rod when it moves downward relative to the clamping frame, thus changing the limiting distance of the adhesive cotton head when it moves downward relative to the clamping opening. The above-mentioned adjusting mechanism achieves the purpose of changing the limiting distance of the pulling mechanism when it moves downward relative to the clamping mechanism through adjustment and movement.

[0005] In this invention, the clamping frame is provided with a sliding groove, and the adjusting seat is installed in the sliding groove and can move along the sliding groove; the pull rod is provided with a stop, and when the adjusting seat moves along the sliding groove to below the stop, the pull rod can limit its downward movement distance by the stop engaging with the adjusting seat. The above structure achieves the purpose of movably installing the adjusting seat on the clamping frame and also achieves the purpose of limiting the distance by engaging the adjusting seat with the pull rod.

[0006] In this invention, the adjusting seat includes an inner seat and an outer seat, which are respectively disposed on both sides of the slide groove. A portion of one of the inner and outer seats passes through the slide groove and is connected to the other via a snap-fit ​​structure. After the inner and outer seats are connected, they are confined within the slide groove. The above structure further optimizes the product.

[0007] In this invention, the gear position includes multiple steps of varying heights, and the distance the pull rod moves relative to the clamping frame varies depending on the level of the adjustment seat when it is moved below each step. This structure further optimizes the product.

[0008] In this invention, the adjusting seat is equipped with a movable switch, which is used to position the adjusting seat after it has moved within the clamping frame. This structure makes the adjusting seat more stable to use.

[0009] In this invention, the adjusting seat has a mounting groove, and the switch is mounted in the mounting groove; the clamping frame has at least one latch, and when the adjusting seat is adjusted and moved to the latch position, the switch enters the latch to position the adjusting seat and the clamping frame; a spring is provided between the switch and the adjusting seat, and the spring keeps the switch in the latchable state; the switch is partially exposed outside the adjusting seat, and when the adjusting seat needs to be moved, it can be disengaged from the latch by pressing the switch. The above structure can achieve the purpose of positioning the adjusting seat after it moves in the clamping frame.

[0010] In this invention, the mounting groove is formed by connecting inner and outer seats, and the switch and spring are confined within the mounting groove. This structure further optimizes the product.

[0011] The advantages of this invention are as follows: Because the plywood mop of this invention is equipped with an adjustment mechanism, the adjustment mechanism moves within the clamping mechanism to change the limiting distance when the pulling mechanism moves downward relative to the clamping mechanism, thereby changing the limiting distance when the plywood head moves downward relative to the clamping opening. The plywood mop with the above structure, through the adjustment of the adjustment mechanism, can pull the relaxed plywood head to a taut state with the clamping opening, thus resulting in better cleaning performance and a longer service life for the plywood head, which is less prone to wobbling.

[0019] Detailed Description of Embodiments: The present invention will be further described below with reference to the accompanying drawings and through embodiments. (Refer to...) Figures 1 to 7 As shown: This invention discloses an adjustment mechanism for a plywood mop. The plywood mop includes a mop handle 1 and a plywood head 2. The lower end of the mop handle is provided with a clamping mechanism 3 for squeezing water from the plywood head, and the clamping mechanism has a clamping opening 4. The plywood head is connected to the mop handle via a pulling mechanism 5. The pulling mechanism moves up and down relative to the mop handle to drive the plywood head into or out of the clamping opening. During dehydration, the pulling mechanism moves upward relative to the mop handle to drive the plywood head into the clamping opening for squeezing and dehydration. The invention is characterized in that: the clamping mechanism is provided with a movable adjustment mechanism 6. The adjustment mechanism moves within the clamping mechanism to change the limiting distance when the pulling mechanism moves downward relative to the clamping mechanism, thereby changing the limiting distance when the plywood head moves downward relative to the clamping opening.

[0020] In this embodiment, the clamping mechanism includes a clamping frame 7, the upper end of which is connected to the lower end of the mop handle. The lower end of the clamping frame has an opening, and pressure rollers are respectively provided on both sides of the opening, forming a clamping opening between them. Multiple sets of pressure rollers can be provided on both sides of the opening. The pulling mechanism includes a pull rod 8 and a driving component 9. One end of the pull rod is connected to the adhesive cotton head, and the other end passes through the clamping frame and is connected to the driving component above. The driving component is movably connected to the mop handle. Movement of the driving component relative to the mop handle can cause the pull rod to move up and down relative to the clamping frame, thereby pulling the rod to drive the adhesive cotton head into or out of the clamping opening. There are many existing technologies for connecting the pull rod to the adhesive cotton head, such as attaching a hard plastic part to the adhesive cotton head or fixing a metal part to the adhesive cotton head. Another method involves connecting the pull rod to a hard plastic part or a metal part. The material components are connected by a snap-fit ​​structure or screws. There are many existing technologies for the driving component, such as: 1) The driving component is sleeved on the mop handle and can slide up and down relative to the mop handle. The upper end of the pull rod is connected to the driving component, and the sliding of the driving component relative to the mop handle can drive the pull rod to move; 2) One end of the driving component is hinged to the mop handle, and the other end can move up and down relative to the mop handle around the hinge point. The upper end of the pull rod is hinged to the driving component and can be driven by the up and down movement of the driving component relative to the mop handle. The driving component can be hinged to the mop handle using a screw structure. The adjustment mechanism includes an adjustment seat 10, which is movably mounted on the clamping frame. The adjustment and movement of the adjustment seat in the clamping frame changes the limiting distance when the pull rod moves down relative to the clamping frame, thereby changing the limiting distance when the cotton head moves down relative to the clamping opening. The clamping frame is provided with a sliding groove 11, and the adjusting seat is installed in the sliding groove and can move along the sliding groove. The pull rod is provided with a stop 12. When the adjusting seat moves along the sliding groove to below the stop, the pull rod can limit its downward movement distance through the stop and the blocking action of the adjusting seat. The adjusting seat includes an inner seat 13 and an outer seat 14, which are respectively located on both sides of the sliding groove. A portion of one of the inner and outer seats passes through the sliding groove and is connected to each other through a snap-fit ​​structure. After the inner and outer seats are connected, they are confined to the sliding groove. There are many existing technologies for snap-fit ​​structures, such as snap-fit ​​structures including hooks and slots, which are respectively located on the inner and outer seats. The inner and outer seats can be connected through the hook and slot structure. The stop includes multiple steps of different heights. When the adjusting seat moves to below different steps, the distance that the pull rod moves downward relative to the clamping frame also varies.

[0021] In this embodiment, the adjusting seat is equipped with a movable switch 16, which is used to position the adjusting seat after it has moved within the clamping frame. The adjusting seat has a mounting groove, and the switch is mounted in the mounting groove. The clamping frame has at least one latch 18; when the adjusting seat moves to the latch position, the switch enters the latch, positioning the adjusting seat and the clamping frame. A spring 19 is provided between the switch and the adjusting seat, providing elasticity and allowing the switch to enter the latch position. The switch is partially exposed outside the adjusting seat; when the adjusting seat needs to move, it can be disengaged from the latch position by pressing the switch. The mounting groove is formed by connecting inner and outer seats, and the switch and spring are confined within the mounting groove.

[0022] The working process of this embodiment is as follows: After the sponge head of the sponge mop is loosened, the user can adjust the adjustment mechanism to move the adjustment seat along the slide groove to below the stop position. Thus, the pull rod can be restricted from moving down by the stop position and the resistance of the adjustment seat. After the distance of the pull rod moving down relative to the clamping frame is changed, the sponge head is tightened relative to the clamping opening and kept in a taut state.

[0023] Because the plywood mop of the present invention is equipped with an adjustment mechanism, the adjustment mechanism moves within the clamping mechanism to change the limiting distance when the pulling mechanism moves downward relative to the clamping mechanism, thereby changing the limiting distance when the plywood head moves downward relative to the clamping opening. The plywood mop with the above structure, through the adjustment of the adjustment mechanism, can pull the relaxed plywood head to a taut state with the clamping opening, thus resulting in better cleaning performance and a longer service life for the plywood head, which is less prone to wobbling.

[0024] The above embodiments are merely examples of the present invention. Any substitutions or combinations between embodiments made in accordance with the spirit of the present invention should be understood as not departing from the protection scope of the present invention.
