Abstract
The utility model discloses a booster oil return pipe which comprises an oil pipe, wherein one end of the oil pipe is connected with a flange, and the other end of the oil pipe is connected with a pipe joint; the pipe joint is a pipe body, wherein a seal ring groove is arranged on the inner wall of one end of the pipe joint, and a thread is arranged on the outer wall of the other end of the pipe joint; one end of the pipe joint, which is provided with the seal ring groove, is connected with the oil pipe; a seal ring is arranged in the seal ring groove; and the oil pipe is provided with a bulge embedded in the seal ring groove to compact the seal ring. The booster oil return pipe has the advantages that the seal ring between the pipe joint and the oil pipe does not drop easily, thereby achieving good tightness and preventing oil leakage very well, and reducing oil loss.
Description
Technical field
The utility model relates to a kind of pressurized machine return tube, relates in particular to a kind of pressurized machine return tube that is used to connect pressurized machine and cylinder block.
Background technique
Pressurized machine return tube on the motor mainly acts on the drainback passage that connects between pressurized machine and the motor; The mainly lubricated pressurized machine bearing of this lubricant oil is used; Lean on the gravity oil return, lubricated pressurized machine after oily temperature be no more than 80 degrees centigrade, pressure is near barometric pressure.Because engine vibration is bigger; Pressurized machine return tube before has the situation of lubricating oil leakage because sealing configuration is simple, and original in addition pressurized machine return tube tube wall is thicker; The problem that assembly error will cause the return tube dress to unmatch slightly greatly; This problem tends to cause assembly line workman complaint, and the consequence that assembling stops production delays the production of motor order.
Summary of the invention
The technical problem that the utility model will solve is: the pressurized machine return tube that a kind of good airproof performance is provided.
In order to solve the problems of the technologies described above; The utility model comprises oil pipe, and an end of oil pipe is connected with flange, and the other end of oil pipe is connected with pipe joint; Pipe joint is that an end inwall has threaded body on seal groove and the other end outer wall; An end of band seal groove is connected with oil pipe on the pipe joint, is provided with seal ring in the seal groove, and oil pipe is provided with and embeds the convexity that compresses seal ring in the seal groove.
For easy for installation, said flange rotates and is arranged on the oil pipe, and the end that oil pipe is used for being connected with flange is provided with the flange of retaining outside the end face of the flange outside.
For the shape of wider adjusting pipe, make and in the process of installing, can avoid interfering that described oil pipe is provided with the multistage corrugated pipe segment.
The utility model beneficial effect: the seal ring difficult drop-off between the utility model pipe joint and the oil pipe, play good sealing property.Can well prevent leakage of oil, reduce oily loss.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the enlarged view of part 4 and the linkage structure of part 2 among Fig. 1;
Among the figure: 1, flange, 2, oil pipe, 2-1, corrugated pipe segment, 3, pipe joint, 4, seal ring.
Embodiment
A kind of pressurized machine return tube as depicted in figs. 1 and 2, it comprises oil pipe 2, and oil pipe 2 is provided with multistage corrugated pipe segment 2-1, and the two ends of oil pipe 2 are straight tube.One end of oil pipe 2 is connected with flange 1, and flange 1 rotates and is arranged on the oil pipe 2, and the end that oil pipe 2 is used for being connected with flange 1 is provided with the flange of retaining outside flange 1 outside end face.
The other end of oil pipe 2 is connected with pipe joint 3; Pipe joint 3 is that an end inwall has threaded body on seal groove and the other end outer wall, and an end of band seal groove is connected with oil pipe 2 on the pipe joint 3, is provided with seal ring 4 in the seal groove; Oil pipe 2 is provided with and embeds the convexity that compresses seal ring 4 in the seal groove; Convexity can adopt inner stamping process to make, pipe joint 3 and oil pipe 2 peg graft good after, the position of corresponding seal groove is carried out punching press and is made in oil pipe 2.
Method for using: flange 1 is directly connected on the pressurized machine, and can rotate at any time, and fitting operation that like this can lineman people convenient for assembly is installed the cylinder block that is screwed in motor behind the compound seal packing ring on the pipe joint 3.
