the utility model provides a run-through hollow fork head flange, includes fork head and thickening flange, the fork head is all connected to both sides on the thickening flange, just set up round connecting screw hole on the thickening flange, the thickening flange is located and all sets up the countersink on the connecting screw hole.

As a further improvement of the above technical scheme:

the two fork heads are integrally connected with the thickened connecting flange, and the two sides of the root of each fork head are in transition with the thickened connecting flange through an arc section.

The thickened connecting flange is located at the arc sections and is provided with a connecting threaded hole, and countersunk holes distributed on the connecting threaded holes between the arc sections can be communicated and processed into countersunk grooves.

The outer side of the countersunk head groove can extend to the outer edge of the thickened connecting flange.

And an R angle is processed at the upper end of the inner side of the countersunk head groove.

And the two corners of the inner side of the countersunk head groove are processed into arc angles.

Compared with the prior art, the utility model has the following beneficial technical effects:

1) The thickened connecting flange is adopted, the thickness of the flange is increased, the torsional strength of the root part of the fork head is enhanced, the bearing capacity of the hollow fork head flange is further enhanced, the service life of a product is prolonged, and the risk of tearing caused by drilling a connecting threaded hole in the root part of the fork head is reduced; the countersunk holes are formed in the positions of the connecting threaded holes, the thickness of the flange at the positions of the countersunk holes is equal to that of the original flange, and the original bolts can be used for completing the connecting operation without changing the original connecting mechanism;

2) The countersunk holes on the connecting threaded holes between the circular arc sections can be communicated and processed into countersunk grooves, so that the countersunk grooves can be directly cut at one time, and the processing efficiency is improved;

3) The two corners on the inner side of the countersunk head groove are processed into arc angles, and the R angle is processed on the upper end of the inner side of the countersunk head groove, so that the smooth position of the countersunk head groove is ensured, and the surface of a product is smooth.
