Description

Technical Field

[0001] This utility model relates to the field of cleaning brush technology, and in particular to a detachable multifunctional cleaning brush. Background Technology

[0002] In the field of cleaning tools, especially when adaptable to different working distances or environments, such as cleaning high places, low places, narrow corners, or large flat surfaces, cleaning brushes are widely used tools in daily life and industrial cleaning. The connecting rod, as a core component, is typically designed with connectable ends: one end connects to the handle or another section of the connecting rod, while the other end connects to specific brush heads or other functional accessories, such as scrapers or window cleaners, via a mounting bracket. To flexibly adjust the working length, a detachable extension sleeve is often fitted over the connecting rod. This sleeve can increase the overall length or provide additional grip points, angle adjustments, or other functions.

[0003] In existing technologies, threaded connections or interference fits are commonly used to connect the connecting rod and its outer sleeve. Threaded connections are cumbersome and time-consuming to install and disassemble, especially when frequent length adjustments or storage are required. After repeated tightening, the threads are prone to wear and stripping, leading to loosening or failure of the connection. Tightening operations may also become difficult when the connecting rod or sleeve is wet or contaminated with cleaning agents. Interference fits rely on the friction generated by the tight fit between the sleeve and the connecting rod for fixation. When axial thrust, tension, or torque is applied to the sleeve (such as vigorous scrubbing, wringing out a mop head, or changing the direction of operation), the sleeve is prone to sliding, rotating, or even loosening on the connecting rod, seriously affecting cleaning efficiency and user experience. The connection reliability is poor, and after long-term use, wear on the friction surfaces will make the connection even more unreliable. Utility Model Content

[0040] The present invention will be further described below with reference to the accompanying drawings.

[0041] Example 1:

[0042] A detachable multi-functional cleaning brush, such as Figure 1-3As shown, the device includes a connecting rod 1 and a mounting base 2. The mounting base 2 is sleeved on the connecting rod 1. A V-shaped clamp 3 is provided inside the connecting rod 1. The movable arm of the V-shaped clamp 3 is provided with a first protrusion 31 and a second protrusion 32 arranged opposite to each other. The first protrusion 31 and the second protrusion 32 are spaced apart along the length of the free arm of the V-shaped clamp 3. The connecting rod 1 has two first through holes 11 corresponding to the first protrusion 31 and the second protrusion 32. The connecting rod 1 has a mounting part 12 that is sleeved on the mounting base 2. A spring buckle 121 protrudes from the outer wall of the mounting part 12. The mounting base 2 has a second through hole 21 corresponding to the spring buckle 121. The connecting rod 1 is fitted with a sleeve 10. The sleeve 10 has holes for the first protrusion 31 and the second protrusion 32 to be inserted. The holes have the same diameter as the first through hole 21 and overlap with each other. The first protrusion 31 and the second protrusion 32 provide a double fixing point for the sleeve 10 and the connecting rod 1, which improves stability. When it is necessary to separate the sleeve 10 from the connecting rod 1, first press the first protrusion 31 and the second protrusion 32, then rotate the sleeve 10 and pull it outward to complete the separation. After rotation, under the restoring force of the V-shaped clamp 3, the first protrusion 31 and the second protrusion 32 abut against the inner wall of the sleeve 10, keeping the connecting rod 1 and the sleeve 10 unlocked. The operation is simple. The mounting part 12 is provided with several spring buckles 121, and the mounting base 2 is provided with several second through holes 21. The spring buckles 121 are inserted into the second through holes 21 to fix the connecting rod 1 and the mounting base 2. The structure is simple and has good stability.

[0043] As a preferred embodiment, such as Figure 12 As shown, the top of the V-shaped clamp 3 is provided with a pull ring 33. The opening direction of the pull ring 33 is perpendicular to the central axis of the connecting rod 1. A pair of movable arms with downward openings extend from below the pull ring 33.
