Description

Technical Field

[0001] This utility model belongs to the field of cleaning tools, and specifically relates to a cleaning tool handle disassembly and assembly structure. Background Technology

[0002] In everyday cleaning tools such as brooms, mops, and window brushes, the working head and extension rod usually need to be connected and disassembled to adapt to different cleaning scenarios. Existing cleaning tool rod connection structures mostly use threaded engagement, snap-locking, or spring clips to achieve assembly and disassembly, but these methods still have many shortcomings.

[0003] For example, although threaded engagement structures provide a secure connection, the disassembly and assembly steps are cumbersome, and the large rotational stroke can easily cause fatigue for users when frequently changing tool heads; spring clip structures usually rely on a single spring clip for positioning, which is not stable enough and is prone to loosening or insecure connection; some structures use a single button to control the pop-out or push-in of the clip, but after long-term use, elastic fatigue or button jamming can also lead to difficulties in disassembly and assembly.

[0004] Furthermore, to meet the current market demand for "modularity, lightweight design, and quick connection," existing cleaning tool connection structures still have room for improvement in terms of reliability and ease of operation. Especially in scenarios requiring one-handed operation, high durability, and a secure connection, existing technologies fail to provide structurally sound and reliable solutions.

[0005] Therefore, there is an urgent need to provide a cleaning tool handle disassembly and assembly structure that is novel in structure, has a stable connection, is easy to disassemble and assemble, and has a moderate manufacturing and assembly cost, so as to meet the dual requirements of efficiency and safety in actual use. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a cleaning tool handle disassembly and assembly structure that is convenient to assemble and disassemble and has high reliability, in light of the current status of the prior art.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cleaning tool handle disassembly and assembly structure, including a first tube and a second tube with a working part, the working part can be a roller brush, a board brush, a hook, etc., which is set on the first tube or the second tube. The second tube is sleeved on the outer periphery of the first tube. The first tube has a pair of first through holes arranged in opposite directions, and a protrusion is provided in the first through hole. The second tube has a locking position to accommodate the protrusion. The first tube also has a V-shaped member, the free end of which is connected to the protrusion. The first tube has a V-shaped ramp that rests on the V-shaped member. The V-shaped member has a button that presses the V-shaped member against the V-shaped ramp. The first tube has a button hole for the button to extend and retract.

[0008] The tool lever can be quickly connected and disconnected through the combination of V-shaped parts, protrusions, and buttons.

[0009] The linkage design of the V-shaped part and the protrusion makes the connection more secure and less likely to fall off accidentally during use.

[0010] Button operation replaces the traditional screw-on or spring-loaded snap-on direct pressing, simplifying the assembly and disassembly process and improving the ease of operation. Users can simply press the button to connect or unlock, saving time and effort. The button can be designed with a large contact surface with the user to enhance pressing comfort.

[0011] The V-shaped ramp provides reliable support and guidance for the V-shaped component, ensuring that the protrusion can smoothly lock or separate from the locking position, avoiding jamming.

[0012] The overall structure is compact, with the V-shaped component concealed within the first tube, which improves aesthetics, reduces the risk of wear or damage to external parts, and extends the product's lifespan.

[0013] In a preferred embodiment, the first tube body is provided with a limiting part that presses against the V-shaped component, and the limiting part and the buttonhole are located on the same side of the V-shaped component. The limiting part provides additional limiting and support for the V-shaped component, effectively preventing displacement or deformation of the V-shaped component under stress or long-term use, thereby ensuring precise alignment and reliable connection between the protrusion and the locking position.

[0014] The design of the limiting part and the buttonhole being located on the same side of the V-shaped part may help with the compact layout and ease of assembly within the structure. At the same time, in some cases, it can provide more stable stress support for the V-shaped part and avoid unnecessary off-center loading.

[0015] In the preferred embodiment, the V-shaped component includes a pivot, and the button includes a hole fitted onto the pivot. Through the cooperation of the pivot and the hole, the force applied to the button can be transmitted more smoothly to the V-shaped component, reducing friction and wear that may occur from direct contact. Compared to a simple push-button connection, this rotary connection method provides a smoother operating feel and effectively improves the user experience.

[0016] In a preferred embodiment, the shaft hole has a width L perpendicular to the button's axial direction, and the rotating shaft has a width K perpendicular to the button's axial direction, where L > K. The design of L > K means that the width of the shaft hole is slightly larger than the width of the rotating shaft, providing appropriate clearance for the rotation of the rotating shaft within the shaft hole. This reduces assembly difficulty and avoids jamming or assembly difficulties caused by excessive tightness. Simultaneously, the appropriate clearance also allows for minor adjustments to the rotating shaft within the shaft hole when the button is pressed, thereby reducing stress concentration and contributing to improved component durability.

[0017] In a preferred embodiment, the shaft hole includes a flat surface facing the button hole, and the rotating shaft includes an arc-shaped surface rolled onto the flat surface. This design of the arc-shaped surface rolling onto the flat surface enables line or surface contact force transmission during button pressing, replacing potential point contact and effectively reducing localized pressure. This "rolling" motion reduces sliding friction, making button pressing and rebound smoother, reducing wear, and further improving the reliability and service life of the mechanism.

[0018] In a preferred embodiment, the button has a first ramp for the rotating shaft to enter the shaft hole, and the rotating shaft has a second ramp corresponding to the first ramp. The cooperation of the first and second ramps provides guidance when the rotating shaft enters the shaft hole, allowing the components to be aligned and assembled more easily and quickly. This "ramp-guided" design greatly simplifies the assembly process on the production line, reduces the difficulty and time cost of manual operation, and improves production efficiency.

[0019] In the preferred embodiment, the pivot is located at the tapered end of the V-shaped component, and the V-shaped ramp is located between the pivot and the protrusion. Positioning the pivot at the tapered end of the V-shaped component helps maintain a more stable structure under force, and allows the button's pressing force to be transmitted more effectively and evenly to the V-shaped component, propelling its movement. The V-shaped ramp, located between the pivot and the protrusion, ensures that the V-shaped component effectively resists the V-shaped ramp when the button is pressed, thereby reliably driving the protrusion to extend and retract, guaranteeing the normal operation of the connecting mechanism. This layout may also contribute to the efficient use of internal space.

[0020] In the preferred embodiment, the locking mechanism is a through hole located on the second tube body. Designing the locking mechanism as a through hole simplifies the structure, facilitates manufacturing and processing, and reduces production costs. The through hole design also facilitates precise alignment and engagement between the protrusion and the locking mechanism, ensuring reliable connection.

[0021] In another embodiment, a cleaning tool handle assembly / disassembly structure includes a first tube with a working part and a second tube fitted onto the first tube. The first tube has a pair of opposing first through holes arranged laterally, each containing a protrusion. The second tube has a locking position to accommodate the protrusion. The first tube also contains a V-shaped component, its free end connected to the protrusion. The first tube has a V-shaped ramp resting on the V-shaped component and a limiting part. A button is located on the V-shaped component, and the limiting part forms a lever structure between the button and the V-shaped ramp. The first tube has a buttonhole for button extension / retraction. This alternative solution further optimizes the button's operating force and feel by introducing a lever structure. The lever structure formed between the limiting part, the button, and the V-shaped ramp means that when the button is pressed, the lever principle can be utilized to achieve a larger force with a smaller force, thereby reducing the user's pressing effort and making assembly / disassembly easier, especially suitable for users with less strength. The lever structure may also provide a longer button travel or more obvious operational feedback, further enhancing the user experience.

[0022] In the preferred embodiment described above, the locking position is a through hole provided on the second tube body. This embodiment provides a simple, easy-to-manufacture, and reliable locking method, applicable to both inventive embodiments.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] 1. High ease of operation: The button operation replaces the traditional screw-on or elastic buckle direct pressing, making the connection and separation of the tool lever faster, less strenuous, and simpler, greatly improving the user experience.

[0025] 2. Secure and reliable connection: The V-shaped parts, protrusions, V-shaped ramps, and limiting parts work together to ensure the stability of the connection, effectively preventing accidental loosening or detachment during use and improving safety.

[0026] 3. Compact and aesthetically pleasing structure: Key disassembly and assembly components are concealed inside the tube body, resulting in a simple and beautiful appearance, and making it less prone to dust accumulation or external impact.

[0027] 4. High applicability: It can effectively meet the needs of frequent disassembly and assembly between cleaning tool heads and extension poles, and is suitable for various cleaning scenarios, such as high-altitude cleaning and replacement of tool heads with different functions.

[0028] 5. Improved operating feel: Through the smooth cooperation between the pivot and the shaft hole, and the introduction of a lever structure in the alternative solution, the pressing force and operating feel of the button have been further optimized, making it lighter and smoother.

[0029] In summary, this invention significantly improves upon existing technologies in terms of convenience, robustness, durability, and production efficiency, providing a high-performance solution for assembling and disassembling cleaning tool handles. Attached Figure Description

[0042] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0043] The reference numerals in the attached drawings are as follows: working part 1, first tube body 2, first through hole 21, V-shaped ramp 22, button hole 23, limiting part 24, second tube body 3, locking position 31, protrusion 41, V-shaped part 42, rotating shaft 43, arc surface 431, second ramp 432, button 5, shaft hole 51, plane 511, first ramp 52.

[0044] Example 1, as Figures 1 to 10 As shown, a detachable cleaning tool handle structure includes a first tube 2 and a second tube 3, each having a working part 1. The working part 1 can be a roller brush, a board brush, a hook, etc., and is mounted on either the first tube 2 or the second tube 3. The second tube 3 is fitted around the outer periphery of the first tube 2. The first tube 2 has a pair of opposing first through holes 21 arranged laterally, with a protrusion 41 in each of the first through holes 21. The second tube 3 has a locking position 31 to accommodate the protrusion 41. The first tube 2 also has a V-shaped component 42 inside, with its free end connected to the protrusion 41. The first tube 2 has a V-shaped ramp 22 that rests on the V-shaped component 42. The V-shaped component 42 has a button 5 that presses the V-shaped component 42 against the V-shaped ramp 22. The first tube 2 has a button hole 23 for extending and retracting the button 5. The second tube 3 serves as an extension handle for the cleaning tool.

[0045] In Example 1, as Figures 1 to 4 As shown, the first tube 2 is provided with a limiting part 24 that presses against the V-shaped member 42, and the limiting part 24 and the buttonhole 23 are located on the same side of the V-shaped member 42.

[0046] In Example 1, as Figures 6 to 10 As shown, the V-shaped component 42 includes a pivot 43, and the button 5 includes a shaft hole 51 fitted onto the pivot 43. Through the cooperation of the pivot 43 and the shaft hole 51, the force applied by the button 5 can be transmitted more smoothly to the V-shaped component 42, reducing friction and wear that may occur from direct contact. Compared to a simple push-button connection, this rotary connection method provides a smoother operating feel and effectively improves the user experience.

[0047] In Example 1, as Figure 10 As shown, the shaft hole 51 has a width L perpendicular to the axis of the button 5, and the rotating shaft 43 has a width K perpendicular to the axis of the button 5, where L > K. The design of L > K means that the width of the shaft hole 51 is slightly larger than the width of the rotating shaft 43, providing an appropriate clearance for the rotation of the rotating shaft 43 within the shaft hole 51. This reduces assembly difficulty and avoids jamming or assembly difficulties caused by excessive tightness. Simultaneously, the appropriate clearance also allows for minor adjustments to the rotating shaft 43 within the shaft hole 51 when the button 5 is pressed, thereby reducing stress concentration and contributing to improved component durability.

[0048] In Example 1, as Figure 10As shown, the shaft hole 51 includes a flat surface 511 facing the button hole 23, and the rotating shaft 43 includes an arc-shaped surface 431 rolled onto the flat surface 511. The design of the arc-shaped surface 431 rolling onto the flat surface 511 enables line or surface contact force transmission during button 5 pressing, replacing potential point contact and effectively reducing local pressure. This "rolling" motion reduces sliding friction, making button 5 pressing and rebounding more smoothly, reducing wear, and further improving the reliability and service life of the mechanism.

[0049] In Example 1, as Figure 7 , 8 As shown, button 5 has a first ramp 52 for the rotating shaft 43 to be assembled into the shaft hole 51, and the rotating shaft 43 has a second ramp 432 corresponding to the first ramp 52. The cooperation of the first ramp 52 and the second ramp 432 provides a guiding effect when assembling the rotating shaft 43 into the shaft hole 51, making it easier and faster for the components to be aligned and smoothly assembled. This "ramp-guided" design greatly simplifies the assembly process on the production line, reduces the difficulty of manual operation and time costs, and improves production efficiency.

[0050] In Example 1, as Figures 1 to 10 As shown, the rotating shaft 43 is located at the tapered end of the V-shaped member 42, as... Figures 1 to 5 As shown, the V-shaped ramp 22 is located between the pivot 43 and the protrusion 41.

[0051] In Example 1, as Figure 3 As shown, the locking position 31 is a through hole provided on the second tube body 3.

[0052] Example 2: The structure of Example 2 is similar to that of Example 1, except that the working part 1 is disposed on the second tube 3. The first tube 2 of Example 2 serves as an extension rod for the cleaning tool.

[0053] Example 3: The structure of Example 3 is similar to that of Example 1, except that the limiting part 24 is located between the button 5 and the V-shaped ramp 22 to form a lever structure, and the button 5 and the limiting part 24 are respectively located on both sides of the V-shaped member 42, as shown below. Figure 11 and Figure 12 As shown. This alternative design further optimizes the operating force and feel of button 5 by introducing a lever structure. A lever structure is formed between the limiting part 24, button 5, and V-shaped ramp 22. This means that when button 5 is pressed, the lever principle can be used to achieve a larger force with a smaller force, thereby reducing the user's pressing effort and making disassembly and assembly easier, especially suitable for users with less strength. The lever structure may also provide a longer button 5 travel or more obvious operational feedback, further enhancing the user experience.

[0054] The working principle of the working part 1 in Embodiment 1 and Embodiment 3: When button 5 is pressed, the V-shaped part 42 is pressed against the V-shaped ramp 22 by button 5, which causes the V-shaped part 42 to be compressed. The two protrusions 41 move closer to each other and retract from the first through hole 21, so that the second tube 3 is put on the first tube 2, and the locking position 31 is aligned with the first through hole 21. Then, button 5 is released, the V-shaped part 42 is released and reset, the protrusions 41 enter the locking position 31, and lock the first tube 2 and the second tube 3.

[0055] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
