The utility model is related to a kind of seal washer sealing structures, including oil pipe, pipe fitting, seal washer, the pipe socket end is provided with external screw thread, externally threaded root is provided with round boss, oil pipe is mounted on by internal thread on pipe fitting, the end of the oil pipe and the round boss of pipe fitting are provided with the seal washer of aluminum, and the structure of restricted seal washer relative motion is set on the round boss of the pipe fitting.The utility model is relatively fixed seal washer position, eccentric during so as to prevent seal washer from assembling, and avoids the generation of oil leak.
Description
Technical field
The utility model is related to a kind of sealing structure, especially a kind of seal washer sealing structure.
Background technology
Seal washer commonly used in mechanical system lubricating oil pipe fitting and oil pipe link position, generally can all select material compared with
Soft aluminum washer so that washer can be bonded after pipe fitting is tightened with the seal face of both sides, realizes sealing.General gasket
Circle is to fit on pipe fitting or nut, needs to reach installation axle journal again by the thread segment of pipe fitting or nut, and axle journal
Position can be smaller than the diameter of thread segment, therefore the fit clearance between seal washer and axle journal is larger, as shown in Figure 1, filling
With the rear easy center for deviateing lubricating oil pipe fitting, leading to seal face, there are gaps, cause oil leak.
Invention content
The purpose of this utility model eliminates the gap of seal washer after mounting, is asked so as to improve the oil leak of seal face
Topic.
The utility model specific technical solution is that the seal washer sealing structure includes oil pipe, pipe fitting, gasket
Circle, the pipe socket end are provided with external screw thread, and externally threaded root is provided with round boss, and oil pipe is provided with and pipe fitting
The matched internal thread of external screw thread, and pass through internal thread on pipe fitting, the end of the oil pipe and the circle of pipe fitting
Shape boss is provided with the seal washer of aluminum, and step cutting pattern, the circle are provided on the round boss of the pipe fitting
Shape outer diameter of step and seal washer minor diameter fit, highly less than the thickness of seal washer.
As another scheme of the utility model, seal washer sealing structure includes oil pipe, pipe fitting, seal washer,
The pipe socket end is provided with external screw thread, and externally threaded root is provided with round boss, oil pipe be provided with outside pipe fitting
The matched internal thread of screw thread, and pass through internal thread on pipe fitting, the end of the oil pipe and the circle of pipe fitting
Boss is provided with the seal washer of aluminum, and annular convex platform, the annular are provided on the round boss of the pipe fitting
Boss internal diameter and seal washer major diameter fit, highly less than the thickness of seal washer.
The utility model is by structure that restricted seal washer is set to move on the round boss of pipe fitting, either
Step cutting pattern or annular convex platform by coordinating with seal washer, are relatively fixed seal washer position, so as to prevent gasket
It is eccentric during circle assembling, avoid the generation of oil leak.

Specific embodiment
As shown in the figure, seal washer sealing structure includes oil pipe 1, pipe fitting 2, seal washer 3,2 end of pipe fitting
Portion is provided with external screw thread, and externally threaded root is provided with round boss 4, and oil pipe 1 is provided with matched with 2 external screw thread of pipe fitting
Internal thread, and pass through internal thread on pipe fitting 2, the end of the oil pipe 1 is set with the round boss 4 of pipe fitting 2
There is the seal washer 3 of aluminum, step cutting pattern 5, the step cutting pattern 5 are provided on the round boss 4 of the pipe fitting 2
Outer diameter and 3 minor diameter fit of seal washer, the highly thickness less than seal washer 3.
As another scheme of the utility model, seal washer sealing structure includes oil pipe 1, pipe fitting 2, seal washer
3,2 end set of pipe fitting has external screw thread, and externally threaded root is provided with round boss 4, and oil pipe 1 is provided with to be connect with pipe
The first matched internal thread of 2 external screw thread, and pass through internal thread on pipe fitting 2, the end of the oil pipe 1 and pipe fitting
2 round boss 4 is provided with the seal washer 3 of aluminum, and annular convex platform is provided on the round boss 4 of the pipe fitting 2
6,6 internal diameter of annular convex platform and 3 major diameter fit of seal washer, the highly thickness less than seal washer 3.
