When universal joint of the present utility model used, its first casing assembly was rotatably connected in the through hole of rotating assembly side by hollow joint pin activity, realizes the rotation of the first casing assembly rotating shaft perpendicular to rotating assembly; The rotating two ends that are connected rotating assembly of second casing assembly; realize the second casing assembly rotating shaft parallel in the rotation of rotating assembly, thereby realize the universal rotation of whole joint, make the signal wire joint plug-in position not be subjected to spatial limitation; effectively save space, guard signal line the end of a thread.
The diameter of described joint pin cooperates with the diametric clearance of described through hole, and the side of described joint pin is provided with stop protrusion vertically, is provided with the projection that cooperates with the stop protrusion of described joint pin in the through hole of described rotating assembly.The diameter of the joint pin of first casing assembly need cooperate with the diametric clearance of the through hole of rotating assembly, prevents when first casing assembly from rotating too loosening; It is excessive in order to prevent the first casing assembly rotational angle that the side of joint pin is provided with stop protrusion vertically, causes holding wire to twist off.
Described rotating assembly two ends are provided with the ring-type extension, described second casing assembly is provided with the bearing of the ring-type extension that can entangle described rotating assembly, such second casing assembly just can entangle rotating assembly two ends and rotation, thereby reduces the volume of second casing assembly.In addition, the structure that the second casing assembly activity is rotatably connected at the two ends of rotating assembly can also adopt the structure the same with the joint pin of first casing assembly, and promptly the inward at both ends of second casing assembly is extended with the movable hollow joint pin that is stuck in the rotating assembly.
The end of described joint pin is provided with the shade limit, and joint pin just can axially block the through hole of rotating assembly like this, can not get loose easily.In addition, this shade limit also can be arranged on the shaft of joint pin, gets final product so long as can block the through hole of rotating assembly vertically.
Described first casing assembly, second casing assembly are divided into the two halves up and down that connect in the buckle mode, so just can be earlier the end of a thread of holding wire be connected, two casing assemblies that close behind the good line of branch get final product the buckle fastening, have simplified the installation process of universal joint, the convenient use.
The utility model has been realized the universal rotation of signal wire joint by using rotating assembly, can make signal wire joint not be subjected to the restriction of narrow space when pegging graft, and effectively saves the space, and guard signal line the end of a thread.
