A high-strength stainless steel fastener

Abstract

The invention discloses a high-strength stainless steel fastener, which is applied in the field of stainless steel fasteners and solves the technical problem of unstable strength of existing fastener components. The feature is that a pair of fan-shaped slots are arranged on the side wall of the riser, and the pair of fan-shaped slots are arranged oppositely, and a vertical rod slot is also provided on the side wall of the riser body, and the vertical rod slot It communicates with one side of the fan-shaped groove on one side, and the middle part of the riser is also provided with a positioning slot, and the positioning slot is vertically arranged with the vertical rod slot, and the top of the rod body is provided with a positioning slot that is inserted into the vertical slot. Connect the matching limit plug, the fan-shaped slot is plugged and slid with a fan-shaped seal block, and a limit patch is fixed under the fan-shaped seal block on the side where the vertical bar slot is located in a pair of the fan-shaped seal blocks , The end of the riser is also vertically provided with a locking groove, which has the technical effect of improving the connection strength of the stainless steel fastener.

Description

technical field [0001] The invention relates to the field of manufacturing stainless steel parts, in particular to a high-strength stainless steel fastener. Background technique [0002] The use of fasteners aims to establish the connection relationship between multiple independent parts through screws and nuts, so as to meet the effect of forming a relatively stable whole between multiple independent parts. Because of its high degree of versatility, the structure and composition of stainless steel fasteners currently on the market are relatively stable, and they can all reflect reliable connection performance. [0003] The Chinese patent whose publication number is CN110094403A discloses a high-strength stainless steel fastener, including a nut, a screw rod and a nut. A storage slot is arranged symmetrically with the axis as the center, a return spring is fixedly installed in the two storage slots, a limit block is placed at one end of the two return springs, and a stopper...

AI Technical Summary

Problems solved by technology

[0004] Although this kind of stainless steel fastener improves the connection strength of the fastener to a certain extent, in actual use, the internal strength of the fastener is mainly improved through elastic connection, but with the long-term use of the fastener , there will be hidden dangers of instability of the elastic parts inside the fastener, which will affect the strength and reliability of the entire stainless steel fastener
