AI Technical Summary

Technical Problem

Existing power cable fault location detection rods are prone to injuring operators or damaging equipment when the torsion spring is in a charged state, and the torsion spring is also prone to fatigue, resulting in structural instability and a poor user experience.

Method used

The upper and middle rods are designed with an asymmetric flat straight cross section. Combined with the locking mechanism of the deformation plate and the fixed rod, the folding and unfolding state of the rods is locked by the deformation of the deformation plate, and the total length is adjusted by the insertion rod and the return spring.

Benefits of technology

It improves the structural stability and operational safety of the detection rod, enhances the user experience, expands the scope of application, and strengthens its applicability and practicality.

Abstract

The utility model relates to the technical field of detection rod, especially to a folding power cable fault positioning detection rod, which comprises a lower rod, a middle rod rotatably connected to the top of the lower rod, an upper rod rotatably connected to the top of the middle rod, an induction probe fixedly connected to the top of the upper rod, a first storage groove formed on the lower rod and the middle rod, a deformation plate fixedly connected to the two sides of the first storage groove, which will deform when pressed, a mounting ring fixedly connected to the lower part of the middle rod and the lower part of the upper rod, a fixing rod slidably connected to the mounting ring, which can be inserted into another rod adjacent to the rod it is in. The utility model uses the deformation plate to lock the position of the folded rod and uses the inserted rod to lock the position of the unfolded rod. The above scheme can increase the stability of the use structure of the utility model and make the operation process safe and convenient, thereby effectively improving the user experience.
