AI Technical Summary

Technical Problem

Under the action of eccentric load, the existing vibration-absorbing hanger is prone to contact with the suspension box, resulting in a significant reduction in vibration-absorbing effect or even failure.

Method used

An anti-offset vibration-absorbing suspension rack is designed, including a first hanging rod, a second hanging rod, a hanging box, a spring, a second pad plate, a limiter shell and a limiter inner sleeve. A first magnetic part is embedded with a second magnetic part through the limiter inner sleeve, and a second magnetic part is embedded with a second magnetic part. The first magnetic part and the second magnetic part are repelled to limit the offset range of the second hanging rod and prevent it from contacting the suspender box.

Benefits of technology

It effectively reduces vibration transmission and ensures the maintenance of vibration damping effect. Even under the action of eccentric load, the second boom can be kept within a safe range and avoid contact with the hoist box.

Abstract

The utility model provides an anti-offset vibration reduction hanging bracket, belongs to the technical field of building vibration reduction, and solves the problem that the vibration reduction effect is obviously reduced and even fails due to the fact that a hanging rod is easy to contact with a hanging box under the action of an eccentric load of a hanging bracket in the prior art. Comprising a first hanging rod, a second hanging rod, a hanging box, a spring, a second base plate, a limiter shell and a limiter inner sleeve. One end of the first hanging rod penetrates out of a first through hole in the upper end of the hanging box and then is located outside the hanging box, one end of the second hanging rod penetrates out of a second through hole in the lower end of the hanging box and then is located outside the hanging box, and the first hanging rod is connected with the hanging box through a connecting assembly. The lower end of the spring is connected with the inner bottom face of the lower end of the hanging box, the limiting stopper shell is fixedly connected to the lower end of the hanging box, the limiting stopper inner sleeve is fixedly connected with the peripheral face of the second hanging rod, a first magnetic piece is embedded in the limiting stopper inner sleeve, and a second magnetic piece repelling the first magnetic piece is embedded in the limiting stopper shell.
