Ceiling finished product access hole device capable of being opened and closed

Abstract

The invention discloses a ceiling finished product access hole device capable of being opened and closed. The ceiling finished product access hole device comprises a light steel keel fixing device, anon-off device and a finished product access hole, wherein the finished product access hole is formed in a gypsum board ceiling. The on-off device comprises a drawing-pulling rod, a fixed sliding railand a moving sliding rail. A close plate of the finished product access hole is fixed to the bottom of the drawing-pulling rod through a connecting piece, a finished product access hole frame is arranged on the periphery of the finished product access hole, the fixed sliding rail is arranged on a keel of the gypsum board ceiling through the light steel keel fixing device, the drawing-pulling rodis movably arranged on the moving sliding rail, the moving sliding rail is connected with the fixed sliding rail through an arc-shaped connecting piece, and the moving sliding rail can rotate relativeto the fixed sliding rail. According to the ceiling finished product access hole device capable of being opened and closed, the access hole device and the periphery of the gypsum board ceiling are consistent, the opening and closing are convenient, brushing and touching to the gypsum board ceiling are avoided when the access hole is opened, a ceiling structure or integrity of the access hole aredamaged, the occupied space is small, the operation is flexible, parts can realize industrialized production, the construction progress is accelerated, and good economic benefits can be achieved.

Description

technical field [0001] The invention belongs to the technical field of architectural decoration, and relates to a planar layout of a gypsum board suspended ceiling of a light steel keel for architectural decoration, in particular to an openable and closable suspended ceiling and an openable product inspection port device. Background technique [0002] Inspection port (abbreviation: inspection hole, inspection port) is a kind of inspection hole that is required in places such as central air-conditioning pipes, wire pipes, toilet water supply and drainage pipes during the decoration process (the inspection hole used by technicians to inspect the internal pipeline of the ceiling) or known as the upper manhole). In the past, the majority of decoration companies often ignored the quality of the inspection openings.

Problems solved by technology

The inspection port is often simply used as a passageway for people. If the plaster access port is removed and placed aside, it is easy to cause damage and pollution to the plaster access port. As domestic mainstream decoration companies began to commonly use finished product access ports, many finished products were derived according to decoration needs.
