Abstract
The utility model discloses a rotary joint, which comprises a joint seat and a rotating body, wherein one end of the joint seat is fixed on a rotary motor, and is communicated with an oil channel in the rotary motor; the other end of the joint seat is sealed; the middle part of the joint seat is provided with a polished rod; one end of the rotating body is provided with an annular hole; the annular hole is sleeved on the polished rod; the polished rod is provided with more than one oil outlet; the oil outlet is communicated with the oil channel; the two ends of the annular hole are provided with gaskets which are inserted into the polished rod; the inner surface of the annular hole is provided with annular grooves at the two ends of the oil outlet respectively; and sealing rings are embedded into the annular grooves. Due to the adoption of a structure disclosed by the utility model, the joint seat is tightly fixed on the rotary motor through a bolt, rotates synchronous to the rotary motor, and is connected tightly. The inner surface of the annular hole is provided with annular grooves at the two ends of the oil outlet respectively, and sealing rings are embedded into the annular grooves, so that oil can be prevented from leaking out of the annular grooves; and meanwhile, the two ends of the annular hole are provided with gaskets which are inserted into the polished rod, so that oil can be further prevented from leaking out of the annular grooves, and the joint seat is hermetically connected with the rotating body.
Description
Technical field
The utility model relates to joint, relates in particular to a kind of swivel joint, is mainly used in the technical field of hydraulic system.
Background technique
At present, in the hydraulic system of engineering mechanical device (for example digging machine, road roller, loader or fork truck etc.) or oil pump etc., being connected with swivel joint of the revolution motor in it into and out of the oil end.Because revolution motor shakes greatly in the course of the work, and together do not stop rotation, be prone to cause connection insecure, make the oil leakage in the swivel joint with swivel joint.
Summary of the invention
In order to overcome the deficiency of existing technology, the purpose of the utility model provides a kind of good airproof performance, the swivel joint that is connected firmly.
A kind of swivel joint of the utility model comprises connection block and solid of rotation, and connection block one end is fixed on the revolution motor; And be communicated with oil circuit in the revolution motor, the other end sealing, the middle part is a polished rod; Solid of rotation one end is a looping pit, and looping pit is set on the polished rod, and polished rod is provided with more than one oil outlet; Oil outlet is communicated with oil circuit; Said looping pit two ends are provided with the pad that is located on the polished rod, and the looping pit internal surface is respectively equipped with circular groove at said oil outlet two ends, is embedded with seal ring in the circular groove.
Said connection block one end is provided with bolt hole, and is fixedly connected with revolution motor by bolt.
Adopt the structure of the utility model, connection block is fixedly secured on revolution motor by bolt, rotates synchronously with revolution motor, is connected firmly.The looping pit internal surface is respectively equipped with circular groove at the oil outlet two ends, is embedded with seal ring in the circular groove, and seal ring can prevent that oil from spilling from circular groove like this; Simultaneously, the looping pit two ends are provided with the pad that is located on the polished rod, can further prevent the circular groove leakage of oil, and connection block and solid of rotation are tightly connected.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model swivel joint.
Embodiment
As shown in Figure 1, a kind of swivel joint of the utility model comprises connection block 1 and solid of rotation 2; Connection block 1 one ends are fixed on the revolution motor, and are communicated with oil circuit in the revolution motor, the other end sealing; The middle part is a polished rod 3, and solid of rotation 2 one ends are looping pit 21, and looping pit 21 is set on the polished rod 3; Polished rod 3 is provided with more than one oil outlet 31, and oil outlet 31 is communicated with oil circuit, and said looping pit 21 two ends are provided with the pad 4 that is located on the polished rod 3; Looping pit 21 internal surfaces are respectively equipped with circular groove 22 at said oil outlet 31 two ends, are embedded with seal ring 5 in the circular groove 22.
Said connection block 1 one ends are provided with bolt hole 11, and are fixedly connected with revolution motor by bolt.
Adopt above structure, connection block 1 is fixedly secured on revolution motor by bolt, rotates synchronously with revolution motor, is connected firmly.Looping pit 21 internal surfaces are respectively equipped with circular groove 22 at oil outlet 31 two ends, are embedded with seal ring 5 in the circular groove 22, and seal ring 5 can prevent that oil from spilling from looping pit 21 like this; Simultaneously, looping pit 21 two ends are provided with the pad 4 that is located on the polished rod 3, can further prevent looping pit 21 leakage of oils, and connection block 1 is tightly connected with solid of rotation 2.
