Problems solved by technology

[0003] During the research process, the inventor found that the existing universal joint has the following disadvantages: when the universal joint is bent in the direction of the force, the rotating pin of the universal joint is under tension Under the action, it will be in contact with the edge of the rotating hole, and there will be friction between the rotating pin and the edge of the rotating hole. Under the action of friction, the edge of the rotating hole will scratch the surface coating of the rotating pin, resulting in serious damage to the rotating pin. seawater corrosion
Therefore, the existing universal joint cannot protect the rotating pin well while avoiding the self-locking phenomenon

Abstract

The embodiment of the invention discloses a universal joint and equipment realized by using the universal joint. The universal joint comprises at least two rotating rings, at least one joint and at least four rotating pins, wherein one end of the joint is connected with the first rotating ring through two embedded rotating pins with certain angle in between; the other end of the joint is connected with the second rotating ring through the other two embedded rotating pins with certain angle in between, wherein the value selection range of certain angle includes 180 degrees, two rotating pins at one end of the joint are parallel to the other two rotating pins at the other end of the joint. While avoiding a self-locking phenomenon, the universal joint provided by the embodiment effectively protects the rotating pins.

Description

technical field [0001] The invention relates to the technical field of universal joints, in particular to a universal joint and equipment realized by using the same. Background technique [0002] Submarine optical cable communication systems generally include road-based equipment, submarine cables and submarine equipment. Submarine cables are connected by subsea equipment. Wherein, the subsea equipment may include a repeater (Repeater), a branching unit (Branching unit) and an equalizer (Equalizer unit). In order to meet construction requirements, these subsea equipment generally include: bending limiter sections, universal joints, and steel straight sections. The gimbal is between the bend limiter section and the steel straight section, inside which the tail cable is stored. The main function of the universal joint is to facilitate construction, transmit the pulling force of the submarine cable, and protect the tail cable at the same time. In order to conform to the con...
