Abstract:
A locking type mop rod, comprising an upper pipe (1), a middle pipe (2), and a lower pipe (3). A handle (4) is fixedly mounted at an outer end of the upper pipe (1), a rotating head (5) is fixedly mounted at an outer end of the handle (4), and a universal joint (6) is fixedly mounted at an outer end of the lower pipe (3); the upper pipe (1) and the middle pipe (2) are fixedly connected by means of a rotation stopping assembly, and the middle pipe (2) and the lower pipe (3) are fixedly connected by means of a rotation stopping assembly; each rotation stopping assembly comprises a rotation stopping base (7) and a rotation stopping head (8); when the upper pipe (1) and the middle pipe (2) as well as the middle pipe (2) and the lower pipe (3) are screwed and connected by means of internal and external threads, a one-way latch matching structure is provided between the rotation stopping base (7) and the rotation stopping head (8), so that the reverse rotation of the rotation stopping base (7) and the rotation stopping head (8) in the screwing direction of the internal and external threads is limited, and sliding between the upper pipe (1) and the middle pipe (2) which are in threaded connection and between the middle pipe (2) and the lower pipe (3) due to thread aging and loosening or an external force action is prevented; the whole product cannot be disassembled after being assembled, so that the situation of mounting loosening in the disassembling and assembling process is prevented; moreover, the used split assembly structure can reduce packaging materials and save packaging and transportation space, and mounting is easy and convenient.
