Abstract

The invention provides an anti-deformation access hole which comprises a frame, a door embedded into the frame of the access hole and locking units. The door comprises a main door body and a transition door body, the upper end and the lower end of a vertical side edge of the transition door body are hinged to the frame through the locking units, and the other vertical side edge of the transition door body is connected with a vertical side edge of the main door body through a hinging structure; and the main door body can overturn by 0-180 degrees and comprises an upper panel, a lower panel and a reinforcing structure located between the upper panel and the lower panel, the reinforcing structure can improve the overall strength of the door, and the door is prevented from deforming in the using process.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to an anti-deformation inspection port. Background technique [0002] Because most of the signal transmission lines, wires, and air-conditioning ducts of buildings are hidden inside the wall or above the ceiling, and once these lines and pipes are damaged or fail, maintenance personnel are required to carry out maintenance work, but the installation It is very inconvenient to open a good wall or ceiling, so when the wall or ceiling is constructed, an additional inspection port structure will be set on the ceiling or wall to facilitate subsequent personnel to maintain lines and pipes. Traditional maintenance There are many shortcomings in the specific use of the port structure. The access door is installed on the side of the equipment access port by means of hinges. The hinge of this method can only be opened and closed at 90°, so that the access door cannot be fully...
