AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

The utility model relates to the technical field of constructional engineering, and discloses a gap width detection tool for constructional engineering, which comprises a plug rod, a scale bar is embedded in the plug rod, an electronic reading device is movably sleeved on the plug rod, a display screen for reading data is mounted on the electronic reading device, and a display screen is mounted on the display screen. A filler gauge piece is arranged at the front end of the plug rod, an L-shaped connecting rod is fixedly connected to the end, close to the filler gauge piece, of the plug rod, and an L-shaped connecting groove used for being matched with the L-shaped connecting rod to assemble the plug rod and the filler gauge piece together is formed in the end, close to the plug rod, of the filler gauge piece. In the utility model, in actual use, the L-shaped connecting rod and the L-shaped connecting groove are matched and clamped to realize primary assembly, and the shifting piece is rotated to drive the threaded rod, so that the top block enters the clamping groove of the L-shaped connecting rod to finish tight connection; when the feeler gauge piece needs to be replaced, the shifting piece is rotated reversely to separate, operation is easy and convenient, and economy and high efficiency are achieved.
