Description

Technical Field

[0002] The ceiling is the structural or decorative layer above an interior space, designed to meet aesthetic needs, as well as provide insulation and heat protection. Most structures feature a canopy (or suspended ceiling) to conceal the roof's structural layer, ensuring optimal indoor use. Also known as a ceiling, canopy, or flat roof, two types of ceilings are commonly used: 1. Exposed ceilings, where the roof or floor structure is directly visible within the interior space. Modern architecture often utilizes reinforced concrete cross-beams or steel pipe grids to enhance the aesthetics of the structure. 2.

[0039] Working state: When installing the ceiling of the present invention, the card block 2 on the assembly plate body 1 is aligned and connected to the card slot 3 on the other assembly plate body 1. In the process of the card block 2 being connected to the card slot 3, the card block 2 squeezes the extrusion block 5 in the card slot 3, thereby putting the first extrusion spring 4 in an extrusion state, thereby improving the card connection stability between the card block 2 and the card slot 3. After the card block 2 and the card slot 3 are aligned and connected, the first connecting block 20 on the assembly plate body 1 is aligned with the corresponding second connecting block 21, that is, by inserting the insertion rod 2202 into the insertion rod In the slot 2201, during this process, the insertion rod 2202 first squeezes the first plug 2204, thereby pushing the second plug 2205 to move, and the insertion rod 2202 squeezes the first plug 2204 in the first connecting block 20 and the second connecting block 21 at the same time, so that the connecting card slot 2207 at the end of the second plug 2205 in the first connecting block 20 is engaged with the connecting card block 2208 at the end of the second plug 2205 in the second connecting block 21. In this case, the first connecting block 20 and the second connecting block 21 are both provided with a fixed structure, and in addition to the connecting card The slot 2207 and the connecting block 2208 are the same as the other connecting structures. Then the plug rod 2202 will be clamped in the limit slot 2211 on the L-shaped block 2210, and the L-shaped block 2210 will be pressed downward until the blocking effect of the L-shaped block 2210 on the third plug block 2212 is released. The third plug block 2212 is fixed in the fixed square slot 2203 on the plug rod 2202 under the action of the third return spring 2214, thereby fixing the position of the plug rod 2202 and realizing the fixed connection between the assembly plate main body 1. When disassembly or maintenance is required, When repairing or replacing, you only need to pull the buckle on the fourth plug-in block 2213 to drive the third plug-in block 2212 to separate from the fixed square groove 2203, and the plug rod 2202 will bounce upward under the action of the second return spring 2209 and the L-shaped stopper 2210, then pull the plug rod 2202 out of the slot 2201, and at this time the second plug-in block 2205 returns to its initial position under the action of the first return spring 2206, that is, the connection between the connecting slot 2207 and the connecting block 2208 is released, and then the block 2 can be separated from the slot 3 to achieve disassembly, which is very convenient.

[0040] The vents and ventilation net 6 are provided on the assembly plate body 1, and a fixed frame is provided at the slot position of the vents. The adjustment block 10 here slides up and down in the fixed frame 7 through the sliding connection of the slide groove 8 and the slider 9. During the sliding process, the adjustment plate 15 can be squeezed so that the adjustment plate 15 enters the groove 12, thereby blocking the ventilation slot 11 in the fixed frame 7. The adjustment plate 15 that is not squeezed is in an inclined state under the action of the second squeezing spring 14, and does not block the ventilation slot 11. Under the supporting action of the second squeezing spring 14 on the adjustment plate 15, it has a supporting effect on the adjustment block 10, that is, By moving the adjusting block 10 up and down in the fixed frame 7, and then by squeezing the adjusting plate 15, the blocking of the ventilation slot 11 by the adjusting plate 15 is controlled, and the ventilation is controlled. Therefore, through the cooperation of the ventilation net 6, the fixed frame 7, the adjusting block 10, the ventilation slot 11 and the adjusting plate 15 provided in the present invention, the ventilation of the ceiling can be adjusted, and the ventilation requirements can be changed according to actual needs to ensure the quality of air circulation; through the assembly plate main body 1 and the fixing device 22 provided in the present invention, the rapid installation of the ceiling can be achieved, which is also very convenient for later disassembly, maintenance and replacement, thereby improving work efficiency and ensuring work economic benefits.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
