Description

Technical Field

[0001] The utility model belongs to the technical field of rotary joints, and in particular relates to a multi-angle adjustment structure of a rotary joint. Background Art

[0002] A rotary joint is a connecting sealing device that inputs fluid media from a stationary pipeline into a rotating or reciprocating device and then discharges it from the rotary joint. It is referred to as a "rotary joint". A rotary joint is a closed rotary connector that rotates 360° to convey the medium. Types of rotary joints: hydraulic rotary joints, high-pressure rotary joints, multi-channel rotary joints, high-speed rotary joints, high-temperature rotary joints, single-channel rotary joints, special rotary joints, LED special rotary joints, excavator special rotary joints, machine tool special rotary joints. Existing rotary joints mainly include a shaft and a bearing that are set as one. The shaft and the bearing are provided with guide grooves that are connected to each other. The shaft and the bearing are respectively installed on a fixed base of the equipment and a rotating part that rotates relative to the base. The bearing is coaxial with the rotating part and is driven by the rotating part to rotate relative to the shaft.

[0003] The existing rotary joint occupies a large area, cannot turn, is prone to leakage and has a short life. Lengthening the metal hose and bending it to change the direction of the hydraulic oil without changing the direction of the oil nozzle can easily cause the metal hose to break and there is a risk of bursting, resulting in a very short service life of the joint. Replacing the joint will delay its use and affect work efficiency. Utility Model Content

The metal hose is lengthened and bent to change the direction of the hydraulic oil without changing the direction of the oil nozzle, which easily causes the metal hose to break and there is a risk of bursting, resulting in a very short service life of the joint. Replacement of the joint will delay its use and affect work efficiency.

[0014] 1. The utility model provides an inclined cylinder and a mounting seat, rotates the rotary joint shell to make the inclined cylinder rotate in the rotating groove in the mounting seat, and adjusts the angle of the rotary joint shell. After the rotary joint adjusts the angle, it can ensure that the rotary joint shell and the mounting seat are seamlessly fitted, thereby ensuring the stability of the rotary joint. The mounting seat is driven to rotate by a motor-driven shaft, and the rotary joint is adjusted at multiple angles. The structure is simple and easy to operate. The angle of the core shaft and the connecting plate can be adjusted only by rotating the rotary joint shell, which is convenient for subsequent installation and use.
