The invention relates to the field of communicating pipes, in particular to a universal joint communicating pipe. The universal joint communicating pipe comprises a communicating pipe main body, a shaft fork, a sealing mechanism, a lubricating mechanism, a placement frame, an abutting block, an abutting rod, a fixing ring, a spring, a ferrule, supporting rods, a pushing block, an oil storage mechanism, a pushing mechanism, a knob and a rotating rod. According to the universal joint communicating pipe, the knob can be manually rotated, the knob rotates to drive the rotating rod to rotate, the rotating rod continuously extrudes and abuts against the abutting block in the rotating process, when the abutting block is extruded and abutted by the rotating rod, the abutting rod moves to drive thepushing block to move, the pushing block moves to extrude lubricating oil located inside the placement frame, then the lubricating oil can be directly injected into the inner wall of the shaft fork,when the rotating rod does not abut against the abutting block any more, the above operation is continuously repeated under the reset effect of the spring, therefore the interior of a connector of theuniversal joint communicating pipe can be directly lubricated during use, the lubricating effect is improved, meanwhile, an additional lubricating device does not need to be used, thereby further facilitating use.
本发明涉及连通管领域,具体的说是一种万向节连通管,包括连通管主体、轴叉、封闭机构、润滑机构、安置框、抵块、抵杆、固定环、弹簧、套环、支杆、推块、储油机构、推进机构、旋钮和转杆。本发明可手动对旋钮进行转动,旋钮转动带动转杆转动,转杆转动过程中,会不断的对抵块进行挤压抵触,当抵块受到转杆的挤压抵触时,抵杆移动带动推块移动,推块移动对处于安置框内部的润滑油进行挤压,则润滑油就会被直接注入至轴叉的内壁上,当转杆不再抵触抵块时,在弹簧的复位作用下,不断的重复上述操作,从而在使用时可直接对万向节连通管的接头内部进行润滑,使得得以提高润滑效果,同时也无需使用另外的润滑装置,进一步方便使用。
