Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown, a kind of detachable collision protection column, including head piece 1,1 bottom of head piece are connected by upper girt strip 2
Middle cross beam 3,3 bottom of middle cross beam by lower girt strip 4 connect cross member 5, the equal welding flange 6 of head piece 1 and 5 both ends of cross member,
Crossbeam screw hole 7 is provided on ring flange 6, lower girt strip 4 is I-shaped shape, and upper girt strip 2 and the top and bottom of lower girt strip 4 are all provided with
There is girt strip screw hole 8, girt strip screw 9 is threaded on girt strip screw hole 8.
Crossbeam screw 10, and 10 other end of crossbeam screw and 11 screw thread of automobile storehouse plate are threaded on crossbeam screw hole 7
