When the inner peripheral surface of the connecting nut of the plug is provided with the protrusions, the socket is provided with the curved grooves, the number of the curved grooves and the circumferential positions of the curved grooves correspond to the number of the protrusions and the circumferential positions of the protrusions, the protrusions are in locking fit with the curved grooves in a hooking mode to achieve anti-falling assembly of the plug and the socket, and the protrusions and the curved grooves form a clamping nail curved groove matching structure for locking and connecting the connecting nut and the socket.
When the inner peripheral surface of the connecting nut of the plug is provided with the bulge loop, the socket is provided with the staple bolt, the number of the staple bolts and the number of the through grooves on the circumferential position of the staple bolts and the bulge loop of the connecting nut correspond to the circumferential position of the through grooves, the staple bolts are locked and matched with the through groove hooks to realize the anti-falling assembly of the plug and the socket, and the staple bolts and the through grooves form a staple bolt curved groove matching structure for locking and connecting the connecting nut and the socket.
When the inner peripheral surface of the connecting nut of the plug is provided with the internal thread, the external thread is arranged on the corresponding socket, the circumferential alignment structure is not arranged between the connecting nut and the plug shell, and after the plug shell is in plug-in fit with the socket, the connecting nut is rotated to enable the connecting nut to be in thread locking assembly with the socket so as to realize the anti-falling assembly of the plug and the socket.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention, the scope of the present invention is defined by the appended claims, and all structural changes that can be made by using the contents of the description and the drawings of the present invention are intended to be embraced therein.
