DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer toFigures 1 to 6 , a decorative foam concrete insulation board ceiling structure, including a ceiling board 1. A hanging rod 2 is arranged on the upper side of the ceiling board 1. A jack 3 is opened on the upper end face of the ceiling board 1 corresponding to the hanging rod 2. A convex block 5 is fixedly installed on the lower end face of the hanging rod 2. A groove 6 is opened on the lower end face inside the jack 3 corresponding to the convex block 5. An inner cavity 4 is opened inside the hanging rod 2. A quick installation mechanism is arranged between the hanging rod 2 and the ceiling board 1. The quick installation mechanism includes a fixing part arranged in the inner cavity 4. The fixing part includes a threaded rod 7 rotatably connected inside the inner cavity 4. Threaded sleeves 8 are helically driven and connected to both sides of the outer surface of the threaded rod 7. Three groups of connecting rods 9 are rotatably connected to the outer surface of the threaded sleeve 8. A push plate 11 is arranged inside the inner cavity 4. A top block 10 is fixedly installed on the inner side of the push plate 11. Three groups of the push plate 11 and the top block 10 are correspondingly arranged. Two groups of connecting rods 9 on the same side are rotatably connected to the corresponding top block 10. A plug rod 12 is fixedly installed at the lower end of the push plate 11. Slots 13 are correspondingly arranged on the inner walls of the inner cavity 4 and the jack 3 for the plug rod 12.

[0028] The thread groove on the outer surface of the threaded rod 7 is a double - thread groove, and a thread groove is separately opened on the lower side of the outer surface of the threaded rod 7.

[0029] A first gear 29 is fixedly installed on the upper side of the outer surface of the threaded rod 7. A second gear 15 is meshed with one side of the first gear 29. A rotating shaft 14 is fixedly installed on the upper end face of the second gear 15. The rotating shaft 14 is rotatably connected to the upper end face inside the inner cavity 4.

[0030] A support ring 16 is fixedly installed on the outer surface of the hanging rod 2. A torsion ring 17 is rotatably connected to the upper end of the support ring 16. A toothed ring 18 is fixedly installed on the inner wall of the torsion ring 17. The toothed ring 18 is meshed with the second gear 15.

[0031] First, before installing the ceiling board 1, the upper end of the hanging rod 2 needs to be fixedly installed with the wall top. Subsequently, the lower end of the hanging rod 2 is inserted into the jack 3 on the ceiling board 1, and the convex block 5 and the groove 6 are correspondingly inserted. Then, the torsion ring 17 is twisted, so that the torsion ring 17 drives the toothed ring 18 to rotate. The second gear 15 is meshed with the toothed ring 18, so the second gear 15 will rotate. The second gear 15 is meshed with the first gear 29 on the threaded rod 7, so the threaded rod 7 will rotate synchronously. The two threaded sleeves 8 helically driven and connected to the outer surface of the threaded rod 7 will move towards each other. Each threaded sleeve 8 will carry three groups of connecting rods 9 to displace. The two groups of connecting rods 9 on the same side are rotatably connected to the top block 10 on the corresponding push plate 11. Therefore, under the cooperation of the two groups of connecting rods 9, the push plate 11 can be driven to displace outward. The three push plates 11 displace outward synchronously, and the plug rod 12 is inserted into the slot 13, preliminarily fixedly connecting the ceiling board 1 and the hanging rod 2.

[0032] The quick installation mechanism further includes a reinforcement member disposed on the lower side inside the inner cavity 4. The reinforcement member includes a threaded plate 19 helically connected to the lower side of the outer surface of the threaded rod 7. A first guiding cavity 20 is formed inside the bump 5. A first flexible alloy rod 23 is slidably connected inside the first guiding cavity 20. One end of the first flexible alloy rod 23 is fixedly connected to the threaded plate 19.

[0033] A limiting cavity 21 is formed on the outer surface of the bump 5. A clamping plate 22 is slidably connected inside the limiting cavity 21. The other end of the first flexible alloy rod 23 extends into the limiting cavity 21 and is fixedly connected to the clamping plate 22.

[0034] The first guiding cavity 20, the bump 5, the groove 6, the first flexible alloy rod 23, the limiting cavity 21 and the clamping plate 22 are all provided in three groups and are dispersedly arranged in a ring shape. The upper ends of the three first flexible alloy rods 23 are all fixedly connected to the threaded plate 19.

[0035] At the same time, the threaded plate 19 helically connected to the lower side of the outer surface of the threaded rod 7 will descend. When the threaded plate 19 descends, it will squeeze the first flexible alloy rod 23, causing the other end of the first flexible alloy rod 23 to extend into the limiting cavity 21, thereby pushing out the clamping plate 22 by half. The three clamping plates 22 extend synchronously, and then cooperate with the action of gravity to clamp and fix the ceiling board 1.

[0036] The quick installation mechanism further includes a locking member disposed on the upper side of the ceiling board 1. The locking member includes three first side plates 24 fixedly installed on the outer surface of the hanging rod 2. A second side plate 25 is disposed between two adjacent first side plates 24. The second side plate 25 is fixedly connected to the ceiling board 1.

[0037] A second guiding cavity 26 is formed inside the second side plate 25. A second flexible alloy rod 27 is slidably connected inside the second guiding cavity 26. One end of the second flexible alloy rod 27 extends into the inner cavity 4 and is fixedly connected to the push plate 11. A fixing groove 28 is formed on the side wall of the first side plate 24 corresponding to the second flexible alloy rod 27.

[0038] The second guiding cavity 26, the second flexible alloy rod 27 and the fixing groove 28 are all symmetrically arranged in two groups. One ends of the two second flexible alloy rods 27 are all fixedly connected to the push plate 11.

[0039] When the hanging rod 2 is inserted into the socket 3, the side panel 25 on the hanging rod 2 is simultaneously inserted between the side panels 1 24 on both sides, and the outward expansion of the push plate 11 will simultaneously squeeze the flexible alloy rod 27, so that the flexible alloy rod 27 extends from the inside of the guide cavity 26 and extends to the inside of the fixing groove 28 on the side panel 1 24, thereby connecting and fixing the side panel 1 24 on the ceiling panel 1 and the side panel 2 25 on the hanging rod 2. At the same time, relying on the self-locking property of the thread, the torsion ring 17 can be prevented from rotating in the opposite direction, thereby releasing the fixation of the ceiling panel 1. When the ceiling panel 1 needs to be removed, the torsion ring 17 can be twisted in the opposite direction to reverse the transmission structure, thereby releasing the fixation.

[0040] The ceiling structure in the related art includes a screw and an insulation board. One end of the screw is connected to the purlin bolt through a connecting plate, and the other end passes through the mounting hole on the insulation board and is fixed with a nut. During installation, the insulation board must first be placed on the screw, and then multiple nuts must be tightened one by one. The operation steps are cumbersome and inefficient. Since each insulation board needs to be fixed separately, it not only increases the construction difficulty, but also prolongs the installation time, affecting the overall construction progress. In actual application, this structure has problems such as inconvenient installation and high labor intensity. It is urgent to optimize the design to improve installation efficiency and construction convenience. Therefore, this solution realizes manual quick assembly between the ceiling board 1 and the hanging rod 2 by setting a quick installation mechanism, greatly improving the installation efficiency. At the same time, reinforcement and locking parts are added to the structure to further lock the connection parts after the initial installation is completed, thereby enhancing the overall fixing effect and effectively preventing the ceiling board 1 from loosening or falling off during use. This design not only simplifies the cumbersome operation of fixing one by one with traditional nuts, but also significantly reduces the construction difficulty, improves the safety and stability of the installation, and is suitable for the efficient construction needs of various indoor ceiling projects.

[0041] The cam 12 is screwed to the top of the cam 13 and the cam 14 is screwed to the top of the cam 13. The cam 12 is screwed to the top of the cam 13 and the cam 14 is screwed to the top of the cam 13. The cam 12 is screwed to the top of the cam 13 and the cam 14 is screwed to the top of the cam 13.

[0042] Meanwhile, the threaded plate 19 helically driven and connected to the lower side of the outer surface of the threaded rod 7 will descend. When the threaded plate 19 descends, it will squeeze the first flexible alloy rod 23, causing the other end of the first flexible alloy rod 23 to extend into the interior of the limiting cavity 21, thereby pushing out the clamping plate 22 by half. The three clamping plates 22 extend synchronously, and then cooperate with the action of gravity to clamp and fix the ceiling plate 1;

[0043] While the hanging rod 2 is inserted into the insertion hole 3, the second side plate 25 on the hanging rod 2 is synchronously clamped between the two first side plates 24. When the push plate 11 expands outward, it will synchronously squeeze the second flexible alloy rod 27, causing the second flexible alloy rod 27 to extend out of the interior of the second guiding cavity 26 and extend into the fixing groove 28 on the first side plate 24, thereby connecting and fixing the first side plate 24 on the ceiling plate 1 and the second side plate 25 on the hanging rod 2. At the same time, relying on the self-locking property of the thread, the reverse rotation of the torsion ring 17 can be avoided, and the fixation of the ceiling plate 1 can be released. When the ceiling plate 1 needs to be disassembled, reverse-twist the torsion ring 17, and the above transmission structure can be reversed, thereby releasing the fixation.

[0044] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
