AI Technical Summary
Traditional one-piece feeler gauges are prone to damage during use, resulting in inaccurate testing accuracy and high replacement costs, making it difficult to meet the high-efficiency and low-cost requirements of construction projects.
A replaceable feeler gauge plate structure was designed, which combines an L-shaped connecting rod, an L-shaped connecting groove and a reinforcing mechanism. The feeler rod and feeler gauge plate are detachably connected by a paddle and a threaded rod. The connection stability and convenient operation are ensured by a limiting block and an elastic top block.
This technology enables the replacement of only the feeler gauge when it is damaged, reducing production costs, improving the accuracy of testing and ease of operation, and adapting to the needs of use in complex construction site environments.
