Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 3, the plug structure with a locking mechanism in this embodiment includes a housing 3, a pin 4, a connecting plate 2, a socket 1, a fixing member 5, a knob 7, a locking post 6, and a spring 8.

The shell 3 is internally provided with a connecting plate 2 used for being connected with a pin 4, the pin 4 is connected with an electric wire and then extends out of the shell 3, the shell 3 is internally provided with a pipe sleeve 1 used for fixing a conducting wire, the inner end of the pipe sleeve 1 is fixedly provided with a fixing piece 5, the outer side wall of the inner end of the pipe sleeve 1 is provided with a threaded part 11, the threaded part 11 is screwed with a knob 7 extending out of the shell 3, the inner end of the knob 7 is provided with an abutting table 7, the outer side wall of the knob 7 is provided with a knob part 72, the fixing piece 5 is provided with a sliding hole 511, the pin 4 comprises a connecting ring 42 and at least two split bodies 41 which are centrosymmetric, the split bodies 41 have elasticity, the split bodies 41 are connected onto the connecting ring 42, the inner side wall of the split bodies 41 is provided with a strip-shaped groove 411, the groove depth of the strip-shaped groove 411 is gradually deepened from the outer end to the inner end, a locking column 6 is inserted into the pin 4, the locking column 6 comprises a thick end 62 and a thin end 61, the thin end 61 is limited in the strip-shaped groove 411, the thin end 61 is sleeved with a spring 8, one end of the other end of the fixing piece 8 abuts against the end of the sliding hole 62 of the thick end, and abuts against the end part 71 of the thick end.

Further, in order to improve the stability of the sliding of the lock post 6, a sliding portion 51 is formed in the fixing member 5, and a sliding hole 511 is opened in the sliding portion 51. Meanwhile, in order to improve the pushing stability of the knob 7 to the locking column 6, a spherical portion is formed at the inner end of the locking column 6, an annular groove is formed in the abutting table 71, and the spherical portion abuts against the inside of the annular groove. Further, in order to facilitate the sliding of the locking post 6 in the strip-shaped slot 411, the outer end of the locking post 6 may also be designed to be a hemispherical structure.

In addition, in the embodiment of the present invention, the pins 4 may have a sheet structure or a column structure.
