Model utility content
Goal of the invention of the present utility model is, the engine oil tube overcoming currently available technology existence connects tight, and oil leakage phenomenon takes place frequently, and loaded down with trivial details defect changed by oil pipe, thus it is convenient and swift to realize a kind of replacing, tubing seal is tight, the flanged joint that reliability is high.
For achieving the above object, the technical solution of the utility model is: a kind of flanged joint, comprise upper flange head and lower flange head, described upper flange head and lower flange head are oppositely arranged, described upper flange head outer race is connected to external thread sleeve, and the flange external diameter of described upper flange head is greater than the center-hole diameter of external thread sleeve; Lower flange head outer race is connected to inner screw sheath, the flange external diameter of described lower flange head is greater than the center-hole diameter of inner screw sheath, described external thread sleeve and the socket of inner screw sheath screw thread folding can coordinate installation, described upper flange head and lower flange cephalic par junction are provided with elastic washer, and described inner screw sheath inner port edge place has the chamfering of inclination.
The flange outer wall of described upper flange head rest nearly external thread sleeve tip inside wall has annular seal groove, in described annular seal groove, is provided with the O-ring seal of elastic material; The flange outer wall of described lower flange head rest nearly inner screw sheath tip inside wall has annular seal groove, in described annular seal groove, is provided with the O-ring seal of elastic material.
On described upper flange head flange jointing end face, circumference uniform distribution is provided with locating bump, and on described lower flange head flange jointing end face, circumference uniform distribution is provided with the location dimples corresponding with upper flange head locating bump, the form fit of locating bump and location dimples.
On described lower flange head flange jointing end face, circumference uniform distribution is provided with locating bump, on described upper flange head flange jointing end face, circumference uniform distribution is provided with the location dimples corresponding with lower flange head locating bump, the form fit of locating bump and location dimples, is used for better locating when assembling.
The beneficial effect of flanged joint of the present utility model:
1. flanged joint of the present utility model, external thread sleeve and the socket of inner screw sheath screw thread folding can coordinate installation, flange folding only needs external thread sleeve and inner screw sheath screw thread to be unscrewed with instrument to screw, convenient disassembly, change gearbox oil pipe convenient and swift, substantially increase the maintenance efficiency of gearbox repairing.
2. flanged joint of the present utility model, upper flange head and lower flange cephalic par junction are provided with elastic washer, upper and lower flange head has annular seal groove on the flange outer wall of external thread sleeve tip inside wall, the O-ring seal of elastic material is provided with in described annular seal groove, achieve double seal, flanged joint sealing effect almost significantly improves, and reliability is very high.
