Detailed Description

As can be seen from fig. 1 and 2, the fire hydrant access hidden door disclosed in the present embodiment includes a door leaf 1, a U-shaped body 2, a first rotating member 3, and a second rotating member 4.

As can be seen from fig. 1 to 3, the first rotating member 3 of the present embodiment includes an upper connecting column 31, a lower connecting column 32 and a ball joint hinge 33, a screw is connected to the upper end of the ball joint hinge 33, a nut seat is connected to the lower end of the ball seat, an internal thread is provided at the lower end section of the upper connecting column, and an external thread is provided at the upper end of the lower connecting column. When the ball head hinge is assembled with the upper connecting column and the lower connecting column, a screw connected with a ball head of the ball head hinge is screwed into the lower end of the upper connecting column, and an external thread head at the upper end of the lower connecting column is screwed into a nut seat at the lower end of the ball head seat.

The second rotating member 4 includes a lower fixed column 41 and an upper fixed column 42, the upper end of the lower fixed column has a vertical shaft, the lower end section of the upper fixed column has an axial hole, and the vertical shaft is inserted into the axial hole.

The U-shaped body 2, the first rotating piece 3 and the second rotating piece 4 form an installation assembly of the door leaf 1, and the installation assembly is divided into two groups which are respectively fixed at the top and the bottom of one side of the door leaf in the height direction.

In this embodiment, the channel steel is used as the U-shaped body 2 because excess material of the construction site can be used.

The structure of the top mounting assembly of the embodiment is as follows: u type body 2 is with its opening vertical layout outwards, and the outer wall of the lower part spliced pole 32 of first rotation piece 3 welds with the inboard top of the 2 left side walls of U type body, and the second rotates the welding of the last fixed column outer wall of piece 4 and the opposite side wall outside bottom of U type body 2, and when assembling with the door leaf frame, the outer wall of lower part fixed column welds with the door leaf frame.

The structure of this embodiment bottom installation component does: u type body 2 is with its opening vertical layout outwards, and the outer wall of the upper portion spliced pole 31 of first rotation piece 3 welds with the inboard bottom of the 2 left side walls of U type body, and the second rotates the lower fixed column outer wall of piece 4 and another lateral wall outside top welding of U type body 2, and when assembling with the leaf frame, the upper fixed column outer wall welds with the leaf frame.

When the mounting component and the door leaf assembly are fixed on the wall surface, the outer ends of the two first rotating pieces are respectively welded with the wall surface steel frameworks above and below the door leaf.

After the hidden door is assembled, the mounting assembly can rotate through the first rotating piece, and the door leaf can rotate through the second rotating piece, as shown in fig. 4 and 5.
