Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a detachable and prefabricated ceiling, including a keel frame 1 and a ceiling panel 5. The keel frame 1 has locking grooves 4 on both sides, and the ceiling panel 5 has a control groove 15 on the inner side. A first threaded rod 10 is rotatably installed inside the control groove 15. Two sets of connecting plates 9 are threadedly connected to the outer side of the first threaded rod 10. A rack 8 is fixedly welded to one side of the connecting plate 9. Two sets of connecting grooves 13 are opened on one side of the ceiling panel 5, which communicate with the control groove 15. A connecting gear 6 is rotatably installed inside the connecting groove 13. The connecting gear 6 meshes with the rack 8. A locking block 7 that matches the locking groove 4 is fixedly welded to one side of the connecting gear 6. When the ceiling panel 5 is flush with the keel frame 1, by rotating the first threaded rod 10, the connecting plate 9 drives the rack 8 to move, thereby driving the locking block 7 to rotate through the connecting gear 6. The locking block 7 extends out and inserts into the locking groove 4, realizing the quick installation of the ceiling panel 5. The inner side of the keel frame 1 is provided with two sets of first limiting grooves 11 that communicate with the control groove 15. The rack 8 is fixedly welded with first limiting blocks 12 on the upper and lower sides. The first limiting blocks 12 are slidably installed inside the first limiting grooves 11 to limit the movement of the rack 8 and prevent the rack 8 from disengaging from the connecting gear 6, thus causing the control device to fail. The ceiling panel 5 has a receiving groove 24 that communicates with the control groove 15 on the front side. The first threaded rod 10 is rotatably installed inside the receiving groove 24 at the nut to prevent the first threaded rod 10 from protruding outward and affecting the appearance. There is a slot 14 at the nut of the first threaded rod 10, and the rotation of the first threaded rod 10 can be controlled from the outside by a slotted screw. The keel frame 1 is fixedly welded to the front and rear sides with connecting frames 2. An extension frame 3 is slidably installed on the outside of the connecting frames 2. A second threaded rod 16 is rotatably installed inside the extension frame 3. The second threaded rod 16 is threaded inside the connecting frame 2. By rotating the second threaded rod 16, the extension frame 3 is moved along the outside of the connecting frame 2. The length of the keel frame 1 can be finely adjusted according to the different sizes of ceiling panels 5. The extension frame 3 has a second limiting groove 18 on both sides inside. The connecting frame 2 has a second limiting block 17 fixedly welded to both sides at one end. The second limiting block 17 is slidably installed inside the second limiting groove 18 to prevent the extension frame 3 from detaching from the connecting frame 2 and to ensure that the extension frame 3 and the connecting frame 2 are tightly fitted to prevent the extension frame 3 from rotating. The extension frame 3 has first positioning pieces 19 on both sides at one end. The ceiling panel 5 has first positioning grooves 20 on both sides to match the first positioning pieces 19. The first positioning pieces 19 are inserted into the first positioning grooves 20 to prevent the ceiling panel 5 from moving back and forth. The upper sides of the keel frame 1 are fixedly welded with second positioning pieces 21. The upper middle part of the ceiling panel 5 has a second positioning groove 22 to match the second positioning pieces 21, so as to ensure that the ceiling panel 5 is positioned when it is pushed up, and to ensure that the locking block 7 is aligned with the locking groove 4. The upper part of the keel frame 1 has mounting grooves 23 on both sides, so that the keel frame 1 can be threadedly connected to the hoisting cable.

[0017] Working principle: When using this utility model, the ceiling panel 5 is lifted upwards, so that the second positioning piece 21 is inserted into the second positioning groove 22. The keel frame 1 on one side of the ceiling panel 5 is adjusted. By rotating the second threaded rod 16, the extension frame 3 is moved along the outside of the connecting frame 2, so that the first positioning piece 19 is inserted into the first positioning groove 20, and the position of the ceiling panel 5 is simply positioned. By rotating the first threaded rod 10, the connecting plate 9 drives the rack 8 to move, so that the locking block 7 is rotated through the connecting gear 6. The locking block 7 extends out and is inserted into the locking groove 4, realizing the quick installation of the ceiling panel 5.
