AI Technical Summary
Technical Problem
Existing flange bolts are prone to loosening after the bolt holes wear, leading to connection failure. Traditional anti-loosening measures are ineffective under wear conditions and have high maintenance costs.
Method used
A flange bolt structure including an adjustment module and a return spring was designed. The adjustment module drives the left and right adjustment blocks to slide, and the return spring compensates for the wear of the bolt holes to achieve the anti-loosening effect.
Benefits of technology
It effectively compensates for bolt hole wear, prevents flange bolts from loosening, reduces maintenance costs, and improves connection stability and safety.

Abstract
The utility model relates to a flange bolt which comprises a head portion and a rod portion, the rod portion is located below the head portion and extends vertically in the axial direction, and the flange bolt further comprises an adjusting module located between the head portion and the rod portion. A left adjusting insertion block and a right adjusting insertion block are arranged on the left side and the right side of the rod part respectively, and a left sliding groove and a right sliding groove for the left adjusting insertion block and the right adjusting insertion block to slide are formed corresponding to the left adjusting insertion block and the right adjusting insertion block. The adjusting module comprises a left adjusting plate abutting against the left adjusting inserting block, a right adjusting plate abutting against the right adjusting inserting block and an adjusting rod used for driving the left adjusting plate and the right adjusting plate to be away from each other, the left side of the left sliding groove is provided with an opening, and the right side of the right sliding groove is provided with an opening. By the adoption of the scheme, when the screw hole is abraded, the left adjusting plate and the right adjusting plate are adjusted to drive the left adjusting inserting block and the right adjusting inserting block to move outwards, and therefore looseness prevention is achieved.
