SUMMERY OF THE UTILITY MODEL
To the above problem, an embodiment of the present invention provides a flange structure for dislocation adjustment.
The utility model discloses the aspect of implementing provides a flange structure for dislocation adjustment, including flange body, bearing and end cover, it is downthehole that bearing end cover and bearing range upon range of flange that sets up on the flange body from top to bottom, the last slot hole of having seted up of end cover.
Compared with the prior art, the beneficial effects of the utility model reside in that: when air supply arrangement installs, can carry out the dislocation adjustment through slot hole on the bearing end cover, can also change the direction of slot hole and then change the dislocation adjustment direction through the swivel bearing end cover simultaneously, install when conveniently appearing the dislocation.
Optionally, a boss is arranged at the bottom of the inner side of the flange hole, the bearing is clamped on the boss, the bottom surface of the bearing end cover compresses the top surface of the bearing, and the top surface of the bearing end cover protrudes out of the flange body.
Optionally, the top surface of the bearing end cover protrudes 2mm from the flange body.
Optionally, the flange body is an octagonal square flange.
Optionally, the number of the flange holes is 8, and the flange holes are symmetrically distributed along the center line of the flange body.
