DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, the utility model provides a high-strength fireproof bridge, including a bridge base plate 1, a mounting block 3 is installed on one side of the bridge base plate 1, an upper cover plate 2 is arranged on the side of the mounting block 3, a hanging frame 4 is installed on one side of the bridge base plate 1, a sliding rod 5 is installed on one side of the bridge base plate 1, a spring 8 is installed on the side of the sliding rod 5, a limiting plate 6 is installed on the side of the sliding rod 5, a connecting block 10 is installed on one side of the limiting plate 6, a pulling plate 7 is installed on one side of the connecting block 10, the sliding rod 5 passes through the pulling plate 7, one end of the limiting plate 6 is installed on the outside of the hanging frame 4, by pulling the pulling plate 7, the pulling plate 7 drives the connecting block 10 to move, and the connecting block 10 drives the limiting plate 6 to move, so that the pulling plate 7 compresses the spring 8, so that the two limiting plates 6 are close to each other, so that the limiting plate 6 no longer restricts the bridge base plate 1, and the bridge base plate 1 is convenient for disassembly and maintenance.

[0022] Among them, a movable groove 11 is opened on one side of the upper cover 2, and a movable groove 2 12 is opened on one side of the movable groove 11. A pressure plate 13 is arranged inside the movable groove 11, and a limit block 16 is installed at one end of the pressure plate 13. Some of the limit blocks 16 are installed with connecting plates 15, and a spring 2 14 is installed on one side of the connecting plate 15. One end of the limit block 16 is arranged inside the mounting block 3. By pulling the pressure plate 13, the pressure plate 13 drives the limit block 16 to move, and the limit block 16 drives the connecting plate 15 to move, so that the connecting plate 15 compresses the spring 2 14, and then the pressure plate 13 is rotated so that the pressure plate 13 enters the movable groove 2 12, so that the limit block 16 is not in the mounting block 3, so that the upper cover 2 can be easily removed.
