[0010] Further, the convex part is fixed with a buffer pad on the wall surface of the side of the fixed rod, and the protective barrel is adapted to the convex part in an arc shape.
[0011] By adopting the above technical scheme, the buffer pad can change the hard contact between the convex part and the protective barrel into soft contact, greatly dispersing the stress when being hit, so that the protective barrel will not be broken at the first time when being extruded.
[0012] The utility model has the advantages of:
[0013] 1. The utility model discloses a connecting column is set up, and the connecting column can fix the corrugated plate and fixed column through bolt, and a plurality of connecting columns and corrugated plate can form the structure of triangle, greatly improve the stability of whole, improve the buffering capacity.
[0014] 2. The utility model discloses a protection bucket and the setting of buffer pad, and buffer pad can change the rigid contact between the convex part and protection bucket into soft contact, greatly disperses the stress when being hit, makes protection bucket when being extruded not first time breakage, and the setting of protection bucket can also greatly improve the whole anti -collision blocking buffering effect.
[0015] Other features and advantages of the present utility model will be set forth in the subsequent description, and, partially become obvious from the description, or be understood by implementing the present utility model. The purpose and other advantages of the present utility model can be realized and obtained through the structure that is pointed out in the description and drawings. BRIEF DESCRIPTION OF DRAWINGS

[0021] In order to make the purpose, technical scheme and advantages of the technical scheme of the utility model more clear, the following text will combine the drawings of the specific embodiment of the utility model, and the technical scheme of the embodiment of the utility model is clearly and completely described. Same reference signs in the drawings represent same parts. It is necessary to explain that the described embodiment is a part of the embodiment of the utility model, not all the embodiment. Based on the described embodiment of the utility model, all other embodiments that the person skilled in the art obtains without the premise of creative labor belong to the scope of protection of the utility model.
[0022] Referring to Figs. 1-3The utility model discloses a municipal road guardrail, including fixed rod 1, be equipped with a plurality of connecting column 2 and protective bucket 3 on fixed rod 1, connecting column 2 is spaced apart with protective bucket 3, and the both sides of fixed rod 1 are equipped with corrugated sheet 4, and the corrugated sheet 4 is divided into recess 41 and convex part 42, recess 41 is recessed towards fixed rod 1, and convex part 42 is protruding towards the side away from fixed rod 1, and one recess 41 and one convex part 42 of the corrugated sheet 4 are regarded as a group, and one corrugated sheet 4 is equipped with a plurality of groups, and the both sides of adjacent corrugated sheet 4 are connected through bolt.
[0023] Referring to Figs. 1-3 , the corrugated sheet 4 is connected with the fixed rod 1 through the connecting column 2, one end of the connecting column 2 is fixed on the fixed rod 1, the other end is fixed with the recess 41 through the bolt, the plurality of connecting columns 2 are divided into a plurality of groups, one group of connecting columns 2 is divided into four, two connecting columns 2 on the same side are directed obliquely upward and obliquely downward, thereby the connecting column 2 on the same side can form a triangular structure with the recess 41, greatly improving the stability and the overall anti-collision blocking buffering capacity.
