Wherein: 1. the device comprises a fixed upright post, a reversible upright post, a fixed round steel, a limit bolt, a railing crosspiece, a U-shaped asymmetric groove, a 6-1 end, a 6-2 end, a b end, a 7 kidney-shaped hole, a 8 and a deck.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in fig. 1-3, a novel reversible railing structure comprises a fixed upright column 1 and a reversible upright column 2 which are fixed on a deck 8, wherein the reversible upright column 2 is positioned between the fixed upright columns 1, railing crosspieces 5 are arranged on the sides of the reversible upright column 2 and the fixed upright column 1, U-shaped asymmetric grooves 6 are formed in the tail ends of the fixed upright columns 1, and waist-shaped round holes 7 and fixed round steel are formed in the reversible upright column 2. When the railing needs to be put down, the reversible upright post 2 is directly lifted, so that the fixed round steel 3 of the reversible upright post 2 exceeds the U-shaped asymmetric groove 6, and then the railing rotates around the limit bolt 4, and therefore the reversible upright post 2 can be rotated, and the railing can be opened.

The fixed upright posts 1 are positioned on two sides of the invertible column 2, and limit bolts are arranged between the fixed upright posts 1. The fixed upright posts 1 can play a limiting role on the invertible upright posts 2, so that the invertible upright posts 2 are always positioned between the fixed upright posts 1, and the limiting bolts 4 can enable the invertible upright posts 2 to rotate between the fixed upright posts 1.

The fixed round steel 3 penetrates through the reversible upright posts 2, the length of the fixed round steel is longer than the distance between the fixed upright posts 1, the limiting bolts 4 are just positioned in the waist-shaped round holes 7 of the reversible upright posts 2, and the reversible upright posts 2 can vertically displace on the limiting bolts 4 through the waist-shaped round holes 7. The reversible upright post 2 is displaced on the limit bolt 4 through the waist-shaped circular hole 7, so that the position relationship between the reversible upright post 2 and the fixed upright post 1 is changed.

The end of the U-shaped asymmetric groove 6 is provided with an a end 6-1 and a b end 6-2, and the height from the a end 6-1 to the U-shaped asymmetric groove 6 is lower than that of the b end 6-2. When the reversible upright post 2 is displaced in the fixed upright post 1, and the fixed round steel 3 is positioned above the a end 6-1, the reversible upright post 2 can rotate towards one side of the a end 6-1, and the reversible upright post is prevented from rotating towards the b end 6-2.

When the limit bolt 4 is positioned at the lowest part of the waist-shaped circular hole 7, the fixed round steel 3 is positioned at the position below the b end 6-2 above the a end 6-1. Thus, the handstand column 2 can only rotate towards the a end 6-1, but not rotate towards the b end 6-2, and the railing can be opened according to the preset direction.

When the limit bolt 4 is positioned at the uppermost part of the waist-shaped circular hole 7, the fixed round steel 3 is positioned at the bottom of the U-shaped symmetrical groove 6 below the a end 6-1. Thus, the reversible upright posts 2 can be vertically arranged between the fixed upright posts 1 to play a role of a railing.

A gap is arranged between the reversible upright post 2 and the fixed upright post 1. The gap between the reversible upright post 2 and the fixed upright post 1 can ensure the smoothness of the rotation of the reversible upright post 2 between the fixed upright posts 1, the phenomenon of blocking does not occur, and the distance between the railing cross bars 5 can ensure that the reversible upright post 2 can not touch the ground when rotating.

As shown in fig. 4-6, the principle of operation is: when the shipside protection height needs to be reduced, the reversible upright post 2 is lifted upwards, the kidney-shaped hole 7 on the reversible upright post 2 is displaced on the limit bolt 4 until the fixed round steel 3 on the reversible upright post 2 is moved out of the U-shaped asymmetric groove 6 and then rotates on the limit bolt 4 towards the a end 6-1 through the kidney-shaped hole 7, so that the height of the railing is reduced, when the height of the railing is needed, the reversible upright post 2 is rotated backwards, then the fixed round steel 3 is rotated into the U-shaped asymmetric groove 6 between the a end 6-1 and the b end 6-2, the verticality of the reversible upright post 2 is realized, and the railing function is realized.

It will be appreciated by persons skilled in the art that the embodiments of the utility model described above and shown in the drawings are by way of example only and not limitation, and that the objects of the utility model have been fully and effectively achieved. The functional and structural principles of the present utility model have been shown and described in the examples and embodiments of the utility model may be modified or practiced without departing from the principles described.
