Foldable chevaux-de-frise fence

Abstract

The invention discloses a foldable chevaux-de-frise fence. The foldable chevaux-de-frise fence comprises multiple chevaux-de-frise main bodies; the adjacent chevaux-de-frise main bodies are connectedwith each other; the chevaux-de-frise main bodies comprise first angle irons and second angle irons; the front and rear sides of the first angle irons and the second angle irons are connected with each other through a plurality of hinged cross pipes; the cross pipes comprise first cross pipes and second cross pipes; the upper and lower ends of the internal sides of the first cross pipes and the second cross pipes are connected with each other; first through holes are correspondingly formed in the upper parts of the front and rear sides of the first angle irons and the second angle irons; key groove type through holes are correspondingly formed in the lower parts of the front and back sides of the first angle irons and the second angle irons; the upper ends of the external sides of the first cross pipes and the second cross pipes are correspondingly connected with the first through holes; and the lower ends of the external sides of the first cross pipes and the second cross pipes are correspondingly connected with the key groove type through holes. The foldable chevaux-de-frise fence has the advantageous effects that the foldable chevaux-de-frise fence can be folded and unfolded, and the foldable chevaux-de-frise fence is conveniently applied to various scenes.
