[0001] The utility model relates to the technical field of fire hydrants, in particular to an anti-collision outdoor fire hydrant casting. Background Art
[0002] Fire hydrants, formally called fire hydrants, are a type of fixed fire-fighting facility. Their main function is to control combustibles, isolate combustible materials, and eliminate sources of fire. They are divided into indoor fire hydrants and outdoor fire hydrants. Fire-fighting systems include outdoor fire hydrant systems, indoor fire hydrant systems, fire extinguisher systems, and some may also have automatic sprinkler systems, water cannon systems, gas fire extinguishing systems, fire detection systems, water mist systems, etc.
[0003] The existing fire hydrant bodies are all made of fire hydrant castings. However, after the fire hydrant castings are installed into the finished fire hydrant, when they are installed on the opposite side for fire fighting, there is no protective measure for the fire hydrant. Once the passing vehicles hit the fire hydrant, the fire hydrant will be damaged, resulting in a waste of water resources and inconvenience to people when it needs to be repaired.
[0004] To solve this problem, the present invention is produced. Utility Model Content

[0016] Figure 2 It is a schematic diagram of the enlarged structure of A in the embodiment of the present utility model. DETAILED DESCRIPTION
[0017] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.
[0018] refer to Figure 1-Figure 2 The embodiment of the utility model discloses: an anti-collision outdoor fire hydrant casting, comprising a fire hydrant body 1, a first connecting plate 2 arranged on the fire hydrant body 1, and a connecting pipe 7, wherein the connecting pipe 7 has a second connecting plate 6 and a third connecting plate 8 at both ends thereof, the first connecting plate 2 and the second connecting plate 6 are connected by an anti-breaking device, the third connecting plate 8 is connected to an external pipeline, and the fire hydrant body 1 and the connecting pipe 7 are connected by an anti-collision device.
[0019] Specifically, the anti-breakage device includes a bellows 9, and a fourth connecting plate 4 and a fifth connecting plate 5 are respectively provided at both ends of the bellows 9. The fourth connecting plate 4 is connected to the first connecting plate 2 by bolts, and the fifth connecting plate 5 is connected to the second connecting plate 6 by bolts.
[0020] Specifically, the anti-collision device includes four anti-collision plates 3, which are evenly distributed around the fire hydrant body 1.
