AI Technical Summary

Technical Problem

When the existing metal frame connection components are expanded later, the crossbar connection components are difficult to slide into the groove, which causes the bolts to bear high loads and are prone to damage. Moreover, the damage is difficult to detect in time, affecting the stability of the system.

Method used

The L-shaped connecting plate is equipped with reinforcing ribs and inserts. Combined with double-ended reverse screws and control linkages, the inserts are inserted and the trapezoidal moving blocks are supported through reverse thread engagement, which distributes the bolt load and prevents damage. The movement trajectory is restricted by parallel sliders and trapezoidal limiting grooves to prevent abnormal wear.

Benefits of technology

It effectively distributes the bolt load, prevents damage, improves the stability and service life of crossbar connections, optimizes manufacturing processes, and improves welding quality and installation safety.

Abstract

This utility model relates to the field of support component technology and discloses a modular metal bracket connection assembly, including an L-shaped connecting plate. Reinforcing ribs are fixed to the inner surface of the L-shaped connecting plate, and inserts are fixed to the outer surface of the L-shaped connecting plate. When workers need to add crossbars, the inserts of the L-shaped connecting plate can be inserted into the vertical part of the T-slot of the crossbar. Then, trapezoidal moving blocks extend into the parallel part of the T-slot, thus forming a T-shape with multiple trapezoidal moving blocks and inserts. When the metal frame is subjected to external force and tends to deform, the trapezoidal moving blocks and inserts can provide support and restraint to the L-shaped connecting plate, thereby sharing the load on the bolts and preventing damage. The control linkage is hexagonal at one end facing the control groove, not exceeding the surface of the L-shaped connecting plate to prevent scratching workers. Workers can also use an internal hexagonal sleeve to control its rotation.
