AI Technical Summary
Existing manhole cover rubber strips cannot be adapted to manhole covers of various heights, resulting in mismatched thicknesses that affect noise reduction and vibration damping effects.
The design combines an L-shaped rubber strip body with an adjustable height pad. Through the cooperation of connecting posts, limiting protrusions, and folding grooves, the pad can be precisely positioned and adjusted. Combined with highly elastic rubber material, it provides good shock absorption and noise reduction performance.
The height of the rubber strip is flexibly adjustable, ensuring simple installation and noise and vibration reduction effects. It adapts to the installation needs of manhole covers of different thicknesses, improving the stability and applicability of the rubber strip.
