AI Technical Summary

⚠Technical Problem

The existing tire puncture test nail plate poses a safety hazard when not in use, and the nails are prone to shaking during the test, affecting the stability of the test.

⚗Method used

A nail structure that can swing around a horizontal axis was designed. Combined with an elastic element, the nail can be automatically stored and locked. During testing, the nail is aligned with the direction of the tire's travel. The elastic force of the elastic element is used to maintain the working state or the stored state. The nail can be detachably fixed on the rotating shaft.

🎯Benefits of technology

It reduces safety hazards when the nail board is not in use, ensures the stability of nails during testing, simplifies the nail replacement and preparation process, and improves ease of operation.

Abstract

This utility model relates to the field of tire testing technology, specifically a nail plate for tire puncture testing. The utility model includes a plate body with a storage hole on its upper surface. A nail, capable of swinging around a horizontal axis, is mounted on the plate body. When swinging, the nail has two states: a retracted state within the storage hole and a working state where its outer end faces upward and protrudes out of the storage hole. When the nail is retracted, its rotation direction is opposite to the tire's direction of travel, and its rotation path avoids the storage hole. When the nail is working, its rotation direction is the same as the tire's direction of travel until the nail body forms abutment with the wall of the storage hole. This utility model allows the nail to be stored away when the nail plate is not being used for testing, reducing safety hazards when the nail plate is not in use.
