[0031] Please refer to Figure 1 - Figure 7This embodiment provides a quick-release telescopic mop, including a handle 1, an adjusting component 2, a telescopic rod 3, a connecting frame 4, a positioning bushing 5, a mounting cover 6, and a docking support plate 7; the two ends of the telescopic rod 3 are respectively connected to the handle 1 and the connecting frame 4; the telescopic rod 3 includes at least two telescopic joints 310 that are slidably connected; the positioning bushing 5 is connected to one end of each telescopic joint 310 facing the handle 1; the positioning bushing 5 includes a positioning ring edge 510 corresponding to the port of the telescopic joint 310 and an anti-wear ring wall 520 extending into the inner cavity of the telescopic joint 310; the docking support plate 7 is sleeved on the outer wall of the telescopic joint 310;

[0032] The upper end of the mounting cover 6 is provided with a docking reference portion 660 corresponding to the positioning ring edge 510; the adjusting member 2 is installed on the mounting cover 6 and is used to adjust the relative position of the telescopic joint 310 relative to the telescopic joint 310; the mounting cover 6 is a split structure including a first half-shell 610 and a second half-shell 620, and also includes a fastener 630 for fastening the connection between the first half-shell 610 and the second half-shell 620; both the first half-shell 610 and the second half-shell 620 include a docking portion 615 corresponding to the docking support plate 7.

[0033] The positioning ring edge 510 is used to prevent the entire positioning bushing 5 from entering the inner cavity of the expansion joint 310, and also serves as an installation mark for the mounting cover 6; the anti-wear ring wall 520 is used to pad between the expansion joint 310 with a larger outer diameter and the expansion joint 310 with a smaller outer diameter to avoid friction and wear between the outer wall of the expansion joint 310 with a smaller outer diameter and the inner wall of the expansion joint 310 with a larger outer diameter.

[0034] In some embodiments, the fastener 630 is a screw and nut assembly.

[0035] When assembling this mop, first, the docking support plate 7 is fitted onto the outer wall of the telescopic joint 310, and then the anti-wear ring wall 520 of the positioning bushing 5 is inserted into the inner cavity of the telescopic joint 310. The positioning ring edge 510 is exposed at the port of the telescopic joint 310, preventing the positioning bushing 5 from continuing to enter the inner cavity of the telescopic joint 310.

[0036] Next, take one of the first half-shell 610 and the second half-shell 620 from the mounting cover 6, align the mating reference part 660 with the positioning ring edge 510, and simultaneously align the mating part 615 with half of the mating support plate 7. Then, take the other half of the first half-shell 610 and the second half-shell 620 from the mounting cover 6, similarly align the mating reference part 660 with the positioning ring edge 510, and align the mating part 615 with the other half of the mating support plate 7, assembling the mounting cover 6. Then, operate the fastener 630 to tighten the connection between the first half-shell 610 and the second half-shell 620, completing the assembly. During the assembly process, there are references between the components, making it convenient and quick.

[0037] When it is necessary to disassemble the mop for maintenance or replace parts, the installation steps described above are reversed. Operate fastener 630 to release the fastening connection between the first half-shell 610 and the second half-shell 620, separate the first half-shell 610 and the second half-shell 620, release the clamping and enclosure of the telescopic rod 3, positioning bushing 5, and docking support plate 7, and then disconnect the positioning bushing 5 and docking support plate 7 from the telescopic joint 310 in sequence. This is convenient, quick, and easy to operate. This structural combination makes the disassembly steps clear and improves the user experience.

[0038] The positioning bushing 5 serves both as a wear-resistant element and as a connecting and positioning element for the mounting cover 6, demonstrating ingenious design. The docking support plate 7 also assists in positioning the first half-shell 610 and the second half-shell 620 as they are assembled into the mounting cover 6, and enhances the structural strength of the mounting cover 6, showcasing a well-thought-out dual-purpose design.

[0039] Since the telescopic joint 310 connected to the handle 1 does not have a stop at its tail, by operating the corresponding adjusting part 2, the handle 1 and the connected telescopic joint 310 can be quickly separated from the telescopic joint 310 below, which can serve as a temporary lock. This prevents others from easily dragging the transport vehicle without the handle 1, thus serving as an anti-theft measure.

[0040] Please refer to Figure 5 and Figure 6 The connecting frame 4 includes a connecting rod 410 and a connecting plate 420; the connection between the connecting frame 4 and the telescopic rod 3 includes a mounting cover 6, an adjusting member 2, and two docking support plates 7; there are two connecting plates 420 located between the two docking support plates 7, and the two connecting plates 420 are respectively located on both sides of the telescopic rod 3; the mounting cover 6 has two docking parts 615 corresponding to the two docking support plates 7; the connecting rod 410 is connected to the connecting plate 420; the mounting cover 6 has a clearance hole 640 corresponding to the connecting plate 420; the adjusting member 2 is used to connect the connecting plate 420 and the telescopic rod 3 into one piece or to disconnect them.

[0041] The two connecting plates 420 and the two docking support plates 7 form a frame structure. After being clamped and connected with the telescopic rod 3, one of the first half-shell 610 and the second half-shell 620 in the mounting cover 6 is held, and the docking part 615 is docked to one half of the two docking support plates 7. Then, the other half of the first half-shell 610 and the second half-shell 620 in the mounting cover 6 is held, and the docking part 615 is docked to the other half of the two docking support plates 7 to assemble the mounting cover 6. Then, the fastener 630 is operated to tighten the connection between the first half-shell 610 and the second half-shell 620, and the assembly is completed.

[0042] Operate the adjusting component 2 to connect the connecting plate 420 and the telescopic rod 3 as a single unit. Alternatively, operate the adjusting component 2 to disconnect the connecting plate 420 from the telescopic rod 3, allowing the connecting frame 4 and the telescopic rod 3 to separate quickly.

[0043] The connecting plate 420 serves three purposes: it forms a frame structure with the docking support plate 7, it connects with the connecting rod 410, and it works with the adjusting component 2 to connect or disconnect the telescopic rod 3. It is a clever design that serves three purposes.

[0044] Please refer to Figure 2 and Figure 6 It includes a limiting end cap 8, which is connected to the end of the telescopic rod 3 away from the handle 1.

[0045] The outer diameter of the limiting end cap 8 is larger than the outer diameter of the telescopic rod 3. This allows the adjusting component 2 to disconnect the connecting plate 420 from the telescopic rod 3. Under the obstruction of the limiting end cap 8, the connecting frame 4 and the telescopic rod 3 cannot be separated.

[0046] Example 1

[0047] Please refer to Figure 4 and Figure 6 The adjusting component 2 includes a double-ended bolt rod 210, a hand-tightening nut 220, a pin nut 230, and an elastic element 240. The two ends of the double-ended bolt rod 210 are respectively connected to the hand-tightening nut 220 and the pin nut 230. The double-ended bolt rod 210 passes through the mounting cover 6, and the hand-tightening nut 220 is located outside the mounting cover 6. The pin nut 230 and the elastic element 240 are located inside the mounting cover 6. The two ends of the elastic element 240 elastically abut against the inner wall of the mounting cover 6 and the pin nut 230, respectively. The telescopic joint 310 has at least two positioning holes 311 corresponding to the pin nut 230 along its length.

[0048] In some embodiments, the elastic element 240 is a cylindrical spring that is sleeved on the double-ended bolt rod 210.

[0049] The elastic force of the cylindrical spring is used to keep the pin nut 230 inserted into the positioning hole 311. The user can release the relative positioning between the telescopic joints 310 by holding the hand-tightening nut 220 and pulling it away from the telescopic rod 3; similarly, the connecting plate 420 is provided with a positioning hole 311 to facilitate cooperation with the adjusting component 2.

[0050] Example 2

[0051] Please refer to Figure 8In this embodiment, the adjusting component 2 includes a double-ended bolt rod 210, a hand-tightening nut 220, a raised nut 250, an elastic element 240, and a retaining element 260. The two ends of the double-ended bolt rod 210 are respectively connected to the hand-tightening nut 220 and the raised nut 250. The double-ended bolt rod 210 passes through the mounting cover 6, and the hand-tightening nut 220 and the elastic element 240 are located on the outside of the mounting cover 6, while the raised nut 250 is located in the inner cavity of the mounting cover 6. The elastic element 240 can be a cylindrical spring, and the two ends of the elastic element 240 elastically abut against the outer wall of the mounting cover 6 and the hand-tightening nut 220, respectively. The mounting cover 6 is provided with a baffle 670 to prevent the raised nut 250 from dislodging from the inner cavity of the mounting cover 6, and the baffle 670 surrounds a through hole adapted to the double-ended bolt rod 210. The retaining member 260 is located in the inner cavity of the telescopic joint 310 with the smallest diameter, and the retaining member 260 includes a spring 261 located in the inner cavity of the telescopic joint 310 and a protruding pin 262 provided at the end of the spring 261; under normal conditions, the protruding pin 262 extends out of the positioning hole 311, and the protruding pin 262 is arranged opposite to the protruding nut 250.

[0052] When adjusting the relative position between telescopic joints 310, i.e., the length of the telescopic rod 3, the user presses the hand-tightening nut 220, causing the protruding nut 250 to move closer to the protruding pin 262. During this process, the elastic force of the elastic element 240 and the spring 261 must be overcome so that the point where the protruding nut 250 and the protruding pin 262 abut against each other is precisely located in the positioning hole 311. Thus, the telescopic joint 310 is no longer obstructed by the protruding pin 262. The user pulls the telescopic joint 310 relative to itself until it reaches the predetermined positioning hole 311. The protruding pin 262, under the elastic force of the spring 261, extends out of the positioning hole 311, re-fixing the length of the telescopic rod 3. During the pulling of the telescopic joint 310, the user can relax the pressure on the hand-tightening nut 220, and the protruding nut 250, driven by the elastic element 240, automatically moves away from the protruding pin 262.

[0053] Preferably, both the protruding pin 262 and the protruding nut 250 are elastic and have a rounded surface 255, which can reduce wear.

[0054] Please refer to Figure 9 Similarly, the mounting cover 6 and adjusting component 2 at the end connecting the telescopic rod 3 and the connecting frame 4 also adopt the above structure, and the connecting plate 420 is provided with positioning hole 311 to facilitate cooperation with the protruding pin 262.

[0055] Please refer to Figure 4 and Figure 6 The docking part 615 is a docking retaining groove or a docking backing plate, and the inner cavity of the mounting cover 6 is also provided with a guide slope 616 that connects with the docking part 615.

[0056] This design makes it easier to assemble and initially connect the first half-shell 610 and the second half-shell 620.

[0057] Please refer to Figure 3 The connecting rod 410 is rotatably connected to the connecting plate 420, and the end of the connecting rod 410 away from the connecting plate 420 is provided with a mounting part 9.

[0058] Mounting component 9 is used to connect to the vehicle body 10. Mounting component 9 can be a tubular structure with one side open, or an angle iron structure.

[0059] Please refer to Figure 6 The connecting plate 420 is provided with a positioning protrusion 421, and the docking support plate 7 is provided with a docking groove 710 corresponding to the positioning protrusion 421.

[0060] This design makes the frame formed by the connecting plate 420 and the docking support plate 7 more stable, and makes it easier to assemble when installing this mop.

[0061] Please refer to Figure 6 Both of the connecting plates 420 are connected to the positioning bushings 5.

[0062] Please refer to Figure 4 The mounting cover 6 has a tapered protrusion 650 corresponding to the hand-tightening nut 220.

[0063] Please refer to Figure 1 - Figure 7 A vehicle, including a quick-release telescopic mop as described above; the vehicle includes a vehicle body 10, the connecting frame 4 is rotatably connected to either the frame or the chassis of the vehicle body 10, and a torsion spring 11 is provided at the rotatable connection.

[0064] The connecting frame 4 is specifically connected to the frame or chassis of the vehicle body 10 via the mounting part 9, screws, and torsion spring 11, and is a rotatable connection. The mounting part 9, screws, and torsion spring 11 form a frame structure with a rebound force, which is used to connect with the connecting rod 410 to enable the mop to automatically rebound and return to its original position during use.
