[0018] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] like Figure 1-4The utility model discloses a safety anti-collision mechanism on a highway bridge, comprising a slot plate 1, and slots 11 and plug plates 12 are arranged on the side walls at both ends of the slot plate 1. The bottom of the slot 11 is arranged in a sealed shape. When the slot plate 1 is spliced, the plug plate 12 can be inserted into the slot 11 to realize the rapid installation and splicing of the slot plate 1. The slot plate 1 is arranged in an open shape on one side, and a buffer device 2 is arranged inside the slot plate 1.

[0021] like Figure 1-3 The buffer device 2 includes a sleeve 3, the interior of the sleeve 3 is arranged in a rectangular groove shape, the sleeve 3 is arranged on the inner wall of the slot plate 1, a telescopic rod 4 is slidably arranged in the sleeve 3, the telescopic rod 4 is a rectangular columnar rod and has the same width and height as the inner groove of the sleeve 3, a spring 5 is arranged inside the sleeve 3, one end of the spring 5 is fixedly connected to the inner wall of the sleeve 3 and the other end is fixedly connected to the telescopic rod 4, and a bracket 6 is arranged at the other end of the telescopic rod 4.
