Technical Field

[0001] The present invention relates to the technical field of ceiling maintenance, and in particular to a maintenance access panel and an installation method thereof. Background Art

[0002] A maintenance opening is a kind of opening that is required in places such as central air-conditioning pipes, electric wire pipes, and bathroom water supply and drainage pipes during the decoration process (a maintenance hole or a manhole, a maintenance door, an inspection hole for technicians to maintain the pipes inside the ceiling or the ceramic tiles and gypsum board walls).

[0003] After the traditional ceiling board is installed, maintenance is rather troublesome. The general maintenance openings on the market are usually small maintenance openings, which need to damage the existing large board surface layer structure during use; while for another kind of small board maintenance opening, the base structure needs to be damaged during the installation process; furthermore, the last board of the existing ceiling board is a fixed board. If the fixed board is damaged when installing the maintenance opening, the top surface layer will be damaged and then the entire ceiling will be damaged. Therefore, the setting of the maintenance opening on the ceiling is extremely important. For example, the patent application number CN201620630948.X discloses a maintenance opening structure for a ceiling, which includes a "T"-shaped double-layer gypsum board for covering the maintenance opening, a double-layer gypsum board for the ceiling, and a light steel keel member. The light steel keel member includes a suspender, a main keel, and a secondary keel. The suspender is fixed to the roof building structure by an expansion bolt, the main keel is fixed to the lower end of the suspender, the secondary keel is hung on the main keel and fixed by a hexagon bolt, the double-layer gypsum board is fixed to the secondary keel by a wood screw to form a square maintenance opening, and a border keel is provided above the edge of the maintenance opening. The "T"-shaped double-layer gypsum board is hung on the double-layer gypsum board forming the maintenance opening. The "T"-shaped double-layer gypsum board of this patent is light in weight, strong in bearing capacity, does not rust, is not easily deformed, and forms an integral body with the ceiling, having good decorative effects and appearance. And when opening the maintenance opening, only need to gently push up the "T"-shaped double-layer gypsum board to open it, without borrowing other tools.

[0004] Therefore, inspired by the prior art, in order to solve the problem that the setting of the maintenance opening does not damage the large board surface layer structure, the base structure, and the ceiling structure, and at the same time, can achieve efficient maintenance of the ceiling, etc., a maintenance access panel and an installation method thereof are designed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following will describe in detail the embodiments of the present invention with reference to the accompanying drawings.

[0035] As Figure 1-2 shown, a maintainable closing plate includes a first panel 1 and a second panel 2. A main body of a rebounder 3 is installed on one side of the first panel 1. The base 4 of the rebounder at the front end of the main body of the rebounder 3 is installed on the wall surface. A plug fitting 6 is installed on the other side of the first panel 1. The plug fitting 6 is connected to the U-shaped keel 9 through the L-shaped angle code 7 at the upper end. On the side of the second panel 2 facing the first panel 1, a plug base 8 is installed. The plug base 8 is adapted to the plug fitting 6.

[0036] The first panel 1 forms a first notch 101 on the side facing the latch fitting 6, and the second panel 2 forms a second notch 201 on the side facing the latch base 8. A connecting member 5 is disposed in the first notch 101 and the second notch 201.

[0037] Specifically, the bumper base 4 is fixed to the wall surface, the bumper body 3 is fixed to the first panel 1, the telescopic portion 401 at the tail of the bumper base 4 cooperates with the installation slot 301 of the bumper body 3. The contraction of the telescopic portion 401 drives the bumper body 3 to approach the wall surface. Correspondingly, the first panel 1 also approaches the wall surface, the latch fitting 6 is separated from the latch base 8, and a maintenance opening appears; the extension of the telescopic portion 401 drives the bumper body 3 away from the wall surface. Correspondingly, the first panel 1 also moves away from the wall surface, and the latch fitting 6 and the latch base 8 are fitted again, realizing the connection of the first panel 1 and the second panel 2. At the same time, the connecting member 5 is installed in the first notch 101 and the second notch 201, further ensuring the stable connection of the first panel 1 and the second panel 2.

[0038] The L-shaped corner bracket 7 through which the latch fitting 6 passes is connected to the channel-shaped keel 9, which ensures that it remains stably connected to the first panel 1 during multiple movements and does not shift in position. At the same time, it can accurately achieve stable cooperation with the latch base 8.

[0039] The bumper base 4 is a magnetic member. The bumper body 3 controls the telescopic movement of the telescopic portion 401 at the tail of the bumper base 4 by controlling the presence or absence of magnetism. Moreover, a spring is provided in the installation slot 301 of the bumper body 3 to prevent damage to the installation slot 301 caused by the rapid telescopic movement of the telescopic portion 401.

[0040] While not damaging the surface layer structure, base structure, and ceiling structure of the large board, the present invention only sets the bumper body 3 and the bumper base 4 at the maintenance position. Relying on the magnetic attraction between the two, the separation and approach between the two boards are completed. The latch cooperation of the latch fitting 6 and the latch base 8 can realize the disassembly and assembly between the two, and at the same time, a maintenance opening is established. Moreover, the structure of the maintenance opening is simple and can achieve rapid and efficient maintenance.

[0041] The present invention does not need to set up a small maintenance opening on the surface layer structure of the large board, nor does it need to damage the base structure to set up a small board maintenance opening. The entire structure is very convenient to install.

[0042] The above-mentioned second panel 2 is only a generalization. The second panel 2 may include one panel or multiple panels connected in sequence.
