AI Technical Summary

Technical Problem

In the installation of existing bathroom equipment, the torque control of fasteners is difficult to control precisely, which can lead to damage to fasteners or base components when overloaded. Furthermore, fasteners are prone to loosening and falling off after installation, affecting the stability of the equipment.

Method used

It adopts a linkage structure of threaded joint and torque limiting part, and achieves precise torque control by preset fracture threshold. The connecting arm design disperses stress to avoid overload damage, and the axial limiting component improves installation stability.

Benefits of technology

It enables precise torque control during the tightening process, avoiding fastener stripping and structural damage, ensuring long-term stability and reliability of the installation, and reducing construction difficulty.

Abstract

The utility model provides a kind of anti-overload fastening assembly, including: threaded joint, with the internal thread matched with fastener;Torque limiting portion, fixedly connected with threaded joint;And when the torque between the torque limiting portion and threaded joint is applied to exceed threshold value, torque limiting portion is separated from threaded joint.The torque limiting portion is arranged around threaded joint, the connection between the torque limiting portion and threaded joint is realized by predetermined fracture structure, the predetermined fracture structure includes a plurality of tapered connecting arms, and the cross-sectional area decreases from the torque transfer portion to the threaded joint direction. Through a kind of anti-overload fastening assembly and the bathroom equipment mounting structure with it, torque control and overload protection in the fastening process are realized, while the stability and reliability of mounting structure are improved.
