Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1

The utility model provides a fire prevention sound insulation door, refer to fig. 1 to 3, the design door body includes left door leaf 2 and right door leaf 3, be to open structure and install in door frame 1, the both sides of left door leaf 2 and right door leaf 3 respectively fix on door frame 1 through bearing hinge 5, install plane thrust ball bearing on the bearing hinge 5, be equipped with sound insulation lock 6 between left door leaf and right door leaf, still install sound insulation mechanism between left door leaf and right door leaf, be equipped with fire-proof sealing strip 7 between the door body and door frame 1, equipment monomer bearing hinge 5's bearing is big in this embodiment, it is stable to open and close.

At least one sealing strip groove is arranged on the door frame 1, and a fireproof sealing strip is arranged in the sealing strip groove.

In this embodiment, transparent observation windows 4 are installed on both the left door leaf and the right door leaf.

Left-hand door leaf and right door leaf all adopt the preparation of 2mm cold-rolled steel sheet, fill the rubber and plastic in the door and inhale sound cotton 9 and sound insulation material 10, and it is effectual to give sound insulation.
