Description

Technical Field

[0001] The utility model relates to the field of building decoration, in particular to a maintenance opening structure. Background Art

[0002] The inspection port is a device that can be opened independently on the ceiling or wall, which is convenient for inspecting the equipment inside the wall or ceiling. The existing inspection port structure usually adopts an embedded installation structure from top to bottom, with a door hole opened in the installation plate layer, and the edge of the inspection door is stuck above the edge of the door hole. However, in this installation method, the edge of the installation plate at the door hole bears all the weight of the inspection door, and the edge of the installation plate will be subject to greater stress. Long-term use will cause the edge of the installation plate to crack and be damaged, thereby destroying the firmness and stability of the inspection port structure. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide an inspection opening structure, in which a fixed frame, a stone mounting plate and a keel are interconnected, so as to improve the structural strength of the inspection opening and improve stability.

A second extension part is also provided on the fixed frame, and the second extension part is connected to the keel; the fixed frame, the stone mounting plate and the keel are connected to each other, which improves the structural strength of the inspection port and has good stability.

[0016] The movable plate is supported by the second extension part to limit the movable plate; at the same time, the movable plate is abutted against the second extension part through the bending part, increasing the contact area between the movable plate and the second extension part, and the force is evenly distributed. The inspection port is sealed by setting a sealing strip to prevent air leakage from the closed inspection port; at the same time, one end of the sealing strip extends to one side of the first extension part to further improve the sealing effect.

[0017] The utility model improves the structural strength of the inspection opening and has good stability by interconnecting the fixed frame, the stone mounting plate and the keel. BRIEF DESCRIPTION OF THE DRAWINGS
