A plumb rod adjustment aid

By using a three-section structure consisting of a card holder, a connecting rod, and a fixing sleeve, the rotation of the ball is driven by the gravity of the centering rod, which solves the problems of difficulty in finding the suspension point and swaying in the vertical suspension method. This enables rapid and stable vertical adjustment of the centering rod, improving adjustment efficiency and accuracy.

AI Technical Summary

⚠Technical Problem

Existing hanging methods are difficult to quickly and stably achieve vertical adjustment of the centering rod in the field or complex environments. The suspension point is difficult to find, the waiting time is long, and it is prone to swaying, which affects the adjustment efficiency and accuracy.

⚗Method used

It adopts a three-section rigid connection structure of card seat, connecting rod and fixing sleeve. The centering rod drives the rotating ball to rotate by its own weight, so as to realize the vertical adjustment of the centering rod. The friction of the rotating ball is controlled and adjusted by the friction block in the ball groove and the lead screw to ensure the precise positioning of the centering rod.

🎯Benefits of technology

It enables rapid and stable vertical adjustment of the center pole without the aid of traditional suspension ropes, improving the efficiency and accuracy of measurement operations, reducing swaying, and simplifying the operation process.
