AI Technical Summary

Technical Problem

The existing insulating tie rods have metal inserts that are directly cast and fixed to the insulation, which requires additional reinforcement connection structures and makes operation inconvenient.

Method used

Design an anti-detachment metal insert for an insulating pull rod. The insert body has a deformation groove at the bottom and a deformation metal plate. The screw drives the deformation metal plate to clamp the insulating material through the action of the transmission component. The insert body is an integral stamped metal column structure with an internal thread groove that matches the inner wall of the fixed groove. The outer side of the deformation metal plate is provided with protruding particles to enhance the internal clamping effect.

Benefits of technology

It enables convenient connection between the insulating tie rod and the circuit breaker, improving the connection's strength and ease of operation, without requiring additional reinforcement structures.

Abstract

An anti-drop metal insert of an insulating pull rod belongs to the field of insulating pull rod accessories and structurally comprises an insert body and a fixing notch. The fixing notch is formed in the center of the top of the insert body and used for being connected with a circuit breaker, an anti-disengaging metal insert is arranged on the insulation pull rod, and through a deformation metal plate which is arranged at the bottom of the insert body and used for strengthening the connection effect with an insulation object, under the action of the transmission assembly, the deformation metal plate internally clamps the inner wall structure of the insulation object. A worker does not need to additionally arrange a reinforcing structure, and operation is convenient.
