Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 6, a foldable guard rail according to an embodiment of the present invention includes a foldable rail body 1 connected to a fixed rail 7 through a folding node, and when a person passes through the foldable rail, the foldable rail is upright, and the person can hold the foldable rail body, thereby improving the passing safety of the person. When no person passes through, collapsible railing level is placed, effectively reduces the risk of falling of personnel and article on the helicopter deck. The folding node comprises a sleeve 2, an end plate 3, a connecting plate 4, a bolt 5 and a stop lever 6. The lower end of the foldable railing body 1 is fixedly connected with the end plate 3, and the end plate 3 connected with the lower end of the foldable railing body 1 is fixedly connected with the connecting plate 4. The end part of the fixed railing pipe 7 is fixedly connected with the end plate 3, and the end plate 3 connected with the end part of the fixed railing pipe 7 is fixedly connected with the connecting plate 4. The connecting plate 4 is provided with a hole for installing the bolt 5, so that the foldable handrail main body 1 can rotate by taking the bolt 5 as an axis, and the handrail main body is in an upright state. Sleeve pipe 2 cup joints with collapsible railing main part 1 activity, and pin 6 and fixed railing 7 fixed connection, and pin 6 carries on spacingly to sleeve pipe 2, and sleeve pipe 2 is located the fixed collapsible railing main part of junction.
