Technical Field

[0001] The invention belongs to the technical field of daily necessities, and particularly relates to a locking mop rod. Background Art

[0002] Mops are often used in daily life for mopping the floor, washing windows, etc.; existing mop handles are divided into two types: integrated and split types. The integrated mop handle is long, which is inconvenient to pack and transport, and consumes packaging materials and takes up transportation space; the commonly used split handles are mostly fixedly connected by threads, which can easily cause slippage between the parts due to loose threads during use, causing inconvenience in operation and even serious injury to the user. Summary of the Invention

[0003] In view of the above problems existing in the prior art, the object of the present invention is to provide a split locking mop handle which can prevent sliding between the split parts and is easy to pack, transport and install.

[0005] The upper tube and the middle tube, and the middle tube and the lower tube are all fixedly connected via a rotation-stopping assembly; the rotation-stopping assembly comprises a rotation-stopping seat and a rotation-stopping head.

[0006] The locking mop rod is characterized in that the side walls on the inner side of the end where the upper tube and the lower tube are connected to the middle tube are provided with internal threads, and the side walls on the outer sides of both ends of the middle tube are provided with external threads matching the internal threads.

[0007] The locking mop rod is characterized in that the inner parts of the ends of the upper tube and the lower tube connected to the middle tube are both clamped with anti-rotation seats, and the anti-rotation seats are respectively fixed to the side walls of the upper tube and the lower tube.

[0008] The locking mop rod is characterized in that both ends of the middle tube are plugged with anti-rotation heads, and the anti-rotation heads are fixed to the side walls of the middle tube.

[0009] The locking mop rod is characterized in that the anti-rotation seat is an annular structure, and an anti-rotation seat latching tooth is provided on the inner side wall of the annular structure.

[0010] The locking mop rod is characterized in that the anti-rotation head includes an insertion end inserted into the middle tube, a limit platform stage, and an anti-rotation section arranged on the limit platform stage. The anti-rotation section includes two symmetrically placed arc-shaped anti-rotation plates, and the outside of the arc-shaped anti-rotation plate is provided with anti-rotation head teeth that match the anti-rotation seat teeth on the anti-rotation seat.

[0011] The locking mop rod is characterized in that the anti-rotation seat teeth and the anti-rotation head teeth are both one-way teeth.

[0012] The locking mop rod is characterized in that sheaths are provided on the outer sides of the connections between the upper tube and the middle tube, and between the middle tube and the lower tube.

[0013] By adopting the above technology, compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] When the upper tube and the middle tube, as well as the middle tube and the lower tube of the present invention are screwed together through the internal and external threads, the one-way tooth matching structure between the anti-rotation seat and the anti-rotation head is used to limit the reverse rotation between the anti-rotation seat and the anti-rotation head along the internal and external threads, thereby preventing the threaded upper tube and the middle tube, as well as the middle tube and the lower tube from sliding due to loosening of the threads due to aging or external force; and the overall product cannot be disassembled after assembly, thereby preventing the occurrence of loose installation during the disassembly and assembly process; in addition, the split assembly structure adopted by the device can reduce packaging materials, save packaging and transportation space, and is simple and convenient to install.

Furthermore, to facilitate a better understanding of the present invention, certain specific details are described in detail below in the detailed description of the present invention. Those skilled in the art will be able to fully understand the present invention without these details.

[0025] See also Figure 1-7 A locking mop rod comprises an upper tube 1, a middle tube 2 and a lower tube 3. The outer end of the upper tube 1 is fixedly mounted with a handle 4, the outer end of the handle 4 is fixedly mounted with a swivel head 5, and the outer end of the lower tube 3 is fixedly mounted with a universal joint 6; the upper tube 1 and the middle tube 2, and the middle tube 2 and the lower tube 3 are fixedly connected by a rotation-stop assembly; the rotation-stop assembly comprises a rotation-stop seat 7 and a rotation-stop head 8.

[0026] The side walls on the inner side of the ends of the upper tube 1 and the lower tube 3 connected to the middle tube 2 are both provided with internal threads 9, and the side walls on the outer sides of both ends of the middle tube 2 are both provided with external threads 10 matching the internal threads 9; the outer sides of the connections between the upper tube 1 and the middle tube 2 and between the middle tube 2 and the lower tube 3 are both provided with sheaths 11.

[0027] The upper tube 1 and the lower tube 3 are connected to the middle tube 2 at one end with a stop seat 7, and the stop seat 7 is fixed to the side walls of the upper tube 1 and the lower tube 3 respectively; the two ends of the middle tube 2 are plugged with a stop head 8, and the stop head 8 is fixed to the side wall of the middle tube 2.

[0028] Among them, the anti-rotation seat 7 is an annular structure, and an anti-rotation seat tooth is provided on the inner side wall of the annular structure; the anti-rotation head 8 includes an insertion end 81 inserted into the middle tube 2, a limit platform stage 82, and a anti-rotation segment 83 arranged on the limit platform stage 82, and the anti-rotation segment 83 includes two symmetrically placed arc-shaped anti-rotation plates 831, and the outside of the arc-shaped anti-rotation plate 831 is provided with an anti-rotation head tooth that matches the anti-rotation seat tooth on the anti-rotation seat 7; the anti-rotation seat tooth and the anti-rotation head tooth are both one-way teeth.
