[0024] Refer to Figure 2 , Figure 3The flat pad assembly comprises a baffle 12 which is vertical and strip-shaped. The vertical structure of the baffle 12 provides a hinge support point for the protective plate 5, and the strip shape of the baffle 12 can extend along the track direction to adapt to the layout of the track fastener. The bottom of the baffle 12 is fixedly connected to the top of the embedded iron seat 3, which ensures the stability of the baffle 12 and the stability of the installation and use of the protective plate 5. The top of the baffle 12 is hingedly connected to the protective plate 5, so that the protective plate 5 can rotate around the hinge point, facilitating operation during installation and maintenance, achieving quick opening and closing. The top of the protective plate 5 is provided with an installation hole 9 which is strip-shaped. The strip-shaped installation hole 9 provides a space for the threaded dowel 6 to pass through, and can adapt to a certain range of positional deviation during installation of the threaded dowel 6, improving the convenience of installation. The inner wall of the installation hole 9 is in contact with the surface of the threaded dowel 6, which ensures that the protective plate 5 can be stably fixed with the tightening of the threaded dowel 6 after installation, preventing the protective plate 5 from shaking. The top end of the threaded dowel 6 successively passes through the insulating rail spacing block 8, the elastic strip 7, the installation hole 9 and extends upward.
