Stainless steel flange with built-in telescopic self-locking mechanism

Abstract

The invention relates to the technical field of hardware fasteners, in particular to a stainless steel flange with a built-in telescopic self-locking mechanism. The flange comprises a flange body made of stainless steel and an assembly bolt matching the flange body. According to the stainless steel flange with the built-in telescopic self-locking mechanism, annular adjusting grooves with built-in external thread adjusting rings and internal thread telescopic locking rings are formed in the positions, located on the periphery of a circular assembling through hole, of the upper end and the lower end correspondingly, the external thread adjusting rings are controlled to rotate through lateral adjusting rods on the arc-shaped face of the outer side of the flange body correspondingly, such that the internal thread telescopic locking rings are controlled to stretch out and draw back internally, a limiting tooth ring is inserted into a limiting tooth groove to complete external locking, so that the assembling stability and firmness of the whole flange are greatly improved; the self-locking mechanism inside the flange is convenient to assemble and disassemble, and the later use cost is reduced; and the self-locking capacity of an internal thread limiting ring can be improved, the internal self-locking mechanism is prevented from loosening, and the safety of the whole flange is further improved.

Description

technical field [0001] The invention relates to the technical field of hardware fasteners, in particular to a stainless steel flange with a built-in telescopic self-locking mechanism. Background technique [0002] Flange bolts are integral bolts consisting of hexagon head, flange (the gasket under the hexagon and the hexagon are fixed together) and screw (cylinder with external thread), which need to be matched with nuts for tightening A part that firmly connects two through holes. [0003] The structure of the traditional flange bolt is simple, just set a flange on the basis of the traditional bolt, most of the structure is fixed, its structure cannot be changed, it cannot be disassembled, and the assembly surface cannot be locked, resulting in relatively limited safety. Contents of the invention [0004] The technical problem to be solved by the present invention is: in order to solve the problems in the above-mentioned background technology, an improved stainless steel...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problems in the above-mentioned background technology, an improved stainless steel flange with a built-in telescopic self-locking mechanism is provided to solve the problem that most of the traditional flange bolts are fixed in structure and cannot be changed. It cannot be disassembled, and at the same time, the assembly surface cannot be locked, resulting in relatively limited safety issues
