Simply put, it refers to the decoration of the ceiling, which is one of the important parts of interior decoration. The ceiling has the functions of heat preservation, heat insulation, sound insulation, and sound absorption, and is also the concealed layer for projects such as electrical, ventilation and air conditioning, communication, and fire prevention and alarm pipeline equipment. Home ceiling installation is a common link in home decoration. Ceilings are classified differently according to the materials of the decorative panels. The ceiling decoration materials are the main basis for distinguishing the ceiling names, mainly including: light steel keel gypsum board ceiling, gypsum board ceiling, mineral wool board ceiling, plywood ceiling, special-shaped long aluminum gusset ceiling, square painted aluminum gusset ceiling, painted glass ceiling, aluminum honeycomb perforated sound-absorbing board ceiling, full-house duplex ceiling, etc.

[0003] A building ceiling mechanism provided by the publication number "CN112796458B" includes a suspension rod, a main keel rod, a hanging member, a secondary keel rod, and a decorative panel. The main keel rod is located below the suspension rod. The middle of the main keel rod is provided with a core cavity, and the top walls at both ends of the core cavity are provided with U-shaped grooves opening outward; the bottom of the hanging member is embedded in the core cavity to hook the end of the main keel rod, the middle part passes upward through the U-shaped groove, and the top is connected to the bottom of the suspension rod.

[0005] In the prior art during ceiling installation, generally, a suspension rod is used to hang the keel and the decorative panel to form a ceiling; usually, the suspension rod is installed after drilling holes in the ceiling in advance. However, during the manual operation process, since workers need to drill suspension holes in the ceiling, it is easy to have drilling deviations, resulting in a mismatch between the suspension rod on the ceiling and it. In this case, installation cannot be carried out and re-drilling is required to install. Moreover, the connection positions of most existing suspension rods and keels are also fixed, thus affecting the normal installation of the ceiling. Summary of the Invention

[0015] Optionally, a fine-tuning mechanism is arranged on one side of the stabilizing block, which can adjust the position where the stabilizing plate contacts the wall surface and improve the stabilizing effect.

[0016] The fine-tuning mechanism includes an adjustment block arranged on one side of the stabilizing block.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] In this application, considering that workers need to drill suspension holes on the ceiling, it is easy to have drilling deviations, resulting in the suspension rods on the suspended ceiling not matching them. In this case, installation cannot be carried out. Therefore, by setting a lateral adjustment mechanism, when the suspension holes and the suspension rods do not match, by pulling the two pulling blocks respectively, the pin rod can be driven to leave the inside of the pin hole. At this time, the first guiding block is no longer restricted. Then, the suspension rod and the first guiding block can be pushed to move laterally along the track of the first guiding groove. When moving to an appropriate position, by releasing the pulling block, the pulling force generated by the tension spring will drive the pulling block and the pin rod to reset, so that the pin rod enters the corresponding pin hole inside, and the first guiding block is restricted again, completing the lateral adjustment of the position of the suspension rod.

[0024] In this application, considering that there will also be longitudinal deviations in the drilling positions during the operation of workers, therefore, by setting a longitudinal adjustment mechanism, by turning the two threaded rods on both sides of the second guiding block, the threaded rods will move upward, and at the same time drive the traction block and the limiting rod to move upward. When the limiting rod leaves the inside of the limiting hole, at this time, the second guiding block, the support beam, the suspension rod and other structures can be driven to move longitudinally. After reaching an appropriate position, turning the threaded rods in the reverse direction can make the threaded rods move downward, and at the same time drive the traction block and the limiting rod to move downward and enter the corresponding limiting hole inside, completing the longitudinal adjustment of the suspension rod.

[0025] In this application, considering that when adjusting, if the distance between the position of the suspension rod and the position of the suspension hole is too large, it will cause deviations in the adjustment. Therefore, by setting a stabilizing mechanism, the keel can be raised to a position close to the ceiling, and then by holding the leverage rod and rotating it, the screwing block, the screwing rod and the first bevel gear can be driven to rotate around the second bearing. The first bevel gear will drive the second bevel gear to rotate, and the second bevel gear will drive the lead screw to rotate around the third bearing. While the lead screw rotates, the moving block and the sliding block will move along the track of the sliding groove. The moving block will drive the stabilizing rod, the stabilizing plate and other structures to approach the wall beside the keel until the stabilizing plate is in close contact with the wall. The friction block on the surface of the stabilizing plate will be in close contact with the wall surface, playing a role of limiting, and then the keel can be limited. After that, workers can adjust the suspension rod more conveniently.

[0026] In this application, considering that the shapes of the walls are different and there may be some pitted places. At this time, if the stabilizing plate is in close contact with the pitted places, the keel cannot be limited. Therefore, by setting a fine-tuning mechanism, by turning the hand-screwed screw, the hand-screwed screw can be made to leave the inside of the adjustment hole, and then the positions of the transmission block, the stabilizing plate and the friction block can be adjusted along the position of the adjustment groove, effectively avoiding the contact between the stabilizing plate and the pitted places on the wall.

[0027] In this application, the horizontal adjustment mechanism and the vertical adjustment mechanism can adjust the position of the suspension rod horizontally and vertically, making it more convenient for installation. At the same time, the stabilization mechanism can adjust structures such as the keel and the suspension rod to a position close to the ceiling and restrict them, so that the positions of the suspension rod and the hanging hole are close, which is beneficial to the accuracy of adjustment. Considering the different shapes of the walls, there may be some pitted areas. At this time, if the stabilizing plate is in close contact with the pitted areas, it cannot limit the keel. Therefore, by setting the fine adjustment mechanism, the positions of the stabilizing plate and the friction block can be adjusted, effectively avoiding the contact between the stabilizing plate and the pitted areas of the wall, and solving the problem that during the manual operation process, due to the need for workers to drill hanging holes on the ceiling, there is an easy occurrence of drilling deviation, resulting in the suspension rods on the suspended ceiling not matching them. In this case, installation cannot be carried out and re-drilling is required for installation. Moreover, the connection positions of most existing suspension rods and keels are also fixed, thus affecting the normal installation of the suspended ceiling. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0041] Please refer to Figures 1-11 , the present application provides a technical solution for a building ceiling.

[0042] Embodiment 1: A building ceiling includes a decorative panel 1, a keel 2 and a plurality of suspension rods 3. The keel 2 is fixedly installed on the top of the decorative panel 1. The suspension rods 3 are located on the top of the keel 2. Two support beams 4 are slidably connected to the top of the keel 2. A first guiding groove 5 is formed on one side of the support beam 4. A plurality of first guiding blocks 6 are slidably connected inside the first guiding groove 5. The top of the first guiding block 6 is fixedly connected to the bottom of the suspension rod 3; a lateral adjustment mechanism is fixedly arranged on the first guiding block 6 and can laterally adjust the position of the suspension rod 3; a longitudinal adjustment mechanism is fixedly arranged on the support beam 4 and can adjust the longitudinal position of the suspension rod 3; a stabilizing mechanism is fixedly arranged on the keel 2 and can limit the position of the keel 2 through the stabilizing mechanism to improve the stability of the keel 2.

[0043] One implementation manner of the first embodiment is as follows: The lateral adjustment mechanism includes support blocks 7 fixedly arranged on both sides of the first guide block 6. The top of the support block 7 is fixedly connected to one side of the first guide block 6. A pulling block 8 is arranged on one side of the first guide block 6. One side of the pulling block 8 is fixedly connected to a pin rod 9. One end of the pin rod 9 penetrates to one side of the support block 7. A plurality of pin holes 10 for cooperating with the pin rod 9 are transversely formed on both sides of the support beam 4.

[0044] In this embodiment, considering that since workers need to drill suspension holes on the ceiling, it is easy to have drilling deviations, resulting in the suspension rods 3 on the ceiling not matching them. In this case, installation cannot be carried out. Therefore, by setting the lateral adjustment mechanism, when the suspension holes do not match the suspension rods 3, by pulling the two pulling blocks 8 respectively, the pin rod 9 is driven to leave the inside of the pin hole 10. At this time, the first guide block 6 is no longer restricted. At this time, the suspension rod 3 and the first guide block 6 can be pushed to be laterally adjusted along the track of the first guide groove 5. When moved to an appropriate position, by releasing the pulling block 8, the pulling force generated by the tension spring 43 will drive the pulling block 8 and the pin rod 9 to reset, so that the pin rod 9 enters the corresponding pin hole 10 inside, and the first guide block 6 is restricted again, completing the lateral adjustment of the position of the suspension rod 3.

[0045] It solves the problem that since workers need to drill suspension holes on the ceiling, it is easy to have drilling deviations, resulting in the suspension rods 3 on the ceiling not matching them, and installation cannot be carried out in this case.

[0046] Preferably, a tension spring 43 is sleeved on the surface of the pin rod 9. One end of the tension spring 43 is fixedly connected to one side of the support block 7, and the other end of the tension spring 43 is fixedly connected to one side of the pulling block 8.

[0047] In this embodiment, by setting the tension spring 43, the pulling force generated by the tension spring 43 can drive the pulling block 8 and the pin rod 9 to reset, so that the pin rod 9 can accurately enter the inside of the pin hole 10, playing a role in resetting.

[0048] Embodiment 2: On the basis of Embodiment 1, in this embodiment, the lateral adjustment mechanism can horizontally adjust the position of the suspension rod 3 to align the position of the suspension rod 3 with the hanging hole. However, considering that there may also be a longitudinal deviation in the punching position during the operation of the worker, in this application, the longitudinal adjustment mechanism includes four second guide blocks 11 fixedly connected to the bottom of the support beam 4. A second guide groove 12 for cooperating with the second guide block 11 is provided on one side of the keel 2. Two connecting rods 13 are fixedly connected to the top of the second guide block 11. A connecting block 14 is fixedly connected to the top of the connecting rod 13. A threaded rod 15 is threadedly connected to the top of the connecting block 14. A first bearing 16 is provided at the bottom of the threaded rod 15. The bottom of the threaded rod 15 penetrates to the bottom of the connecting block 14 and is rotatably connected to a traction block 17 through the first bearing 16. A limiting block 18 is fixedly connected to one side of the traction block 17. Two limiting rods 19 are fixedly connected to the bottom of the limiting block 18. A plurality of limiting holes 20 for cooperating with the limiting rods 19 are longitudinally provided at the top of the keel 2.

[0049] In this embodiment, considering that there may also be a longitudinal deviation in the punching position during the operation of the worker, therefore, by setting the longitudinal adjustment mechanism, the two threaded rods 15 on both sides of the second guide block 11 can be screwed. The threaded rod 15 will move upward, and at the same time drive the traction block 17 and the limiting rod 19 to move upward. When the limiting rod 19 leaves the inside of the limiting hole 20, at this time, the structures such as the second guide block 11, the support beam 4 and the suspension rod 3 can be driven to move longitudinally. After reaching the appropriate position, screwing the threaded rod 15 in the reverse direction can make the threaded rod 15 move downward, and at the same time drive the traction block 17 and the limiting rod 19 to move downward and enter the corresponding limiting hole 20 to complete the longitudinal adjustment of the suspension rod 3; the problem that there may also be a longitudinal deviation in the punching position during the operation of the worker is solved.

[0050] Embodiment 3: On the basis of Embodiment 2, in this embodiment, the lateral adjustment mechanism and the longitudinal adjustment mechanism can adjust the lateral position and the longitudinal position of the suspension rod 3. However, considering that during the adjustment, if the distance between the position of the suspension rod 3 and the position of the hanging hole is too large, it will cause deviation during the adjustment. In this application, the stabilizing mechanism includes four stabilizing blocks 21 fixedly connected to both sides of the keel 2. A transmission groove 22 is provided inside the stabilizing block 21. A first bevel gear 23 is provided inside the transmission groove 22. A screwing rod 24 is fixedly connected to the top of the first bevel gear 23. The top of the screwing rod 24 penetrates to the outside of the stabilizing block 21 and is fixedly connected to a screwing block 25. A second bevel gear 26 is meshed with one side of the first bevel gear 23. A lead screw 27 is fixedly connected to one side of the second bevel gear 26. A moving block 28 is drivingly connected to the surface of the lead screw 27. Two stabilizing rods 29 are fixedly connected to one side of the moving block 28. Two stabilizing plates 30 are provided on one side of the stabilizing block 21.

[0051] In this embodiment, considering that if the distance between the position of the suspension rod 3 and the position of the suspension hole is too large during adjustment, it will cause deviation in the adjustment. Therefore, by setting a stabilizing mechanism, the keel 2 can be raised to a position close to the ceiling, and then by holding the leverage rod 41 and rotating it, the screwing block 25, the screwing rod 24, and the first bevel gear 23 can be driven to rotate around the second bearing 37. The first bevel gear 23 will drive the second bevel gear 26 to rotate, and the second bevel gear 26 will drive the lead screw 27 to rotate around the third bearing 38. While the lead screw 27 rotates, the moving block 28 and the sliding block 39 will move along the track of the sliding groove 40. The moving block 28 will drive structures such as the stabilizing rod 29 and the stabilizing plate 30 close to the wall beside the keel 2 until the stabilizing plate 30 is in close contact with the wall. The friction block 36 on the surface of the stabilizing plate 30 will be in close contact with the wall surface, playing a role of limiting, and then limiting the keel 2. After that, the worker can adjust the suspension rod 3 more conveniently.

[0052] It solves the problem that considering that if the distance between the position of the suspension rod 3 and the position of the suspension hole is too large during adjustment, it will cause deviation in the adjustment.

[0053] Preferably, a second bearing 37 is provided at the bottom of the first bevel gear 23. The bottom of the first bevel gear 23 is rotationally connected to the inner wall of the transmission groove 22 through the second bearing 37. One end of the lead screw 27 is provided with a third bearing 38 and is rotationally connected to the inner wall of the transmission groove 22 through the third bearing 38.

[0054] In this embodiment, by setting the second bearing 37 and the third bearing 38, it can play a role of supporting and limiting structures such as the first bevel gear 23, the second bevel gear 26, and the lead screw 27, so that the first bevel gear 23 and the second bevel gear 26 always remain in a meshed state, and at the same time, it can also ensure that their rotation process is more smooth.

[0055] Preferably, a sliding block 39 is fixedly connected to the bottom of the moving block 28, and a sliding groove 40 matching with the sliding block 39 is opened on the inner wall of the transmission groove 22.

[0056] In this embodiment, by setting the sliding block 39 and the sliding groove 40, it can play a limiting role on the moving block 28 during the process of driving the moving block 28 when the lead screw 27 rotates, restricting it to move along the track of the sliding groove 40 only together with the sliding block 39.

[0057] Preferably, leverage rods 41 are fixedly connected to both sides of the screwing block 25, and an anti-slip pad 42 is sleeved on the surface of the leverage rods 41.

[0058] In this embodiment, by setting the leverage rods 41 and the anti-slip pad 42, it can provide a leverage point for the worker to rotate the screwing block 25. At the same time, the anti-slip pad 42 can improve the comfort during the rotation process and play an anti-slip role.

[0059] Preferably, a friction block 36 is fixedly connected to one side of the stabilizing plate 30, which can improve the friction force when the stabilizing plate 30 contacts the wall.

[0060] In this embodiment, by providing the friction block 36, the friction force when the stabilizing plate 30 contacts the wall surface can be improved, preventing the downward slide caused by the gravity of the keel 2 and failing to achieve the function of limiting the keel 2.

[0061] Embodiment 4: On the basis of Embodiment 3, in this embodiment, the stabilizing mechanism can lift the keel 2 to a position close to the ceiling, and then use the wall surface as a support point and cooperate with the stabilizing mechanism to position the keel 2, so as to facilitate the workers to adjust the position of the suspender 3. However, considering the different shapes of the walls, there may be some pitted areas. At this time, when the stabilizing plate 30 is in close contact with the pitted areas, it cannot limit the keel 2. In this application, a fine-tuning mechanism is provided on one side of the stabilizing block 21, which can adjust the position where the stabilizing plate 30 contacts the wall surface and improve the stabilizing effect.

[0062] The fine-tuning mechanism includes an adjustment block 31 provided on one side of the stabilizing block 21. One end of the stabilizing rod 29 penetrates to one side of the stabilizing block 21 and is fixedly connected to one side of the adjustment block 31. Two adjustment slots 32 are opened on one side of the adjustment block 31. A transmission block 33 is slidably connected inside the adjustment slot 32. One side of the transmission block 33 is fixedly connected to one side of the adjustment block 31. A hand-tightening screw 34 is threadedly connected to the top of the transmission block 33. A number of adjustment holes 35 for cooperating with the hand-tightening screw 34 are opened on the top of the adjustment block 31.

[0063] In this embodiment, considering the different shapes of the walls, there may be some pitted areas. At this time, when the stabilizing plate 30 is in close contact with the pitted areas, it cannot limit the keel 2. Therefore, by providing the fine-tuning mechanism, the position of the transmission block 33, the stabilizing plate 30 and the friction block 36 can be adjusted along the position of the adjustment slot 32 by turning the hand-tightening screw 34 so that the hand-tightening screw 34 leaves the inside of the adjustment hole 35, effectively avoiding the contact between the stabilizing plate 30 and the pitted areas of the wall.

[0064] It solves the problem that considering the different shapes of the walls, there may be some pitted areas. At this time, when the stabilizing plate 30 is in close contact with the pitted areas, it cannot limit the keel 2.

[0065] Working principle: First, turn the hand-tightening screw 34 so that the hand-tightening screw 34 leaves the inside of the adjustment hole 35, and then the positions of the transmission block 33, the stabilizing plate 30 and the friction block 36 can be adjusted along the position of the adjustment slot 32 to avoid the contact between the stabilizing plate 30 and the pitted areas of the wall.

[0066] After raising the keel 2 to a position close to the ceiling, hold the leverage rod 41 and rotate it, thereby driving the screwing block 25, the screwing rod 24, and the first bevel gear 23 to rotate around the second bearing 37. The first bevel gear 23 will drive the second bevel gear 26 to rotate, and the second bevel gear 26 will drive the lead screw 27 to rotate around the third bearing 38. While the lead screw 27 is rotating, the moving block 28 and the sliding block 39 will move along the track of the sliding groove 40. The moving block 28 will drive structures such as the stabilizing rod 29 and the stabilizing plate 30 closer to the wall beside the keel 2 until the stabilizing plate 30 is in close contact with the wall. The friction block 36 on the surface of the stabilizing plate 30 will be in close contact with the wall surface to achieve the limiting effect.

[0067] When the hanging hole does not match the suspension rod 3, by pulling the two pulling blocks 8 respectively, the pin rod 9 is driven to leave the inside of the pin hole 10. At this time, the first guiding block 6 has no restriction, and then the suspension rod 3 and the first guiding block 6 can be pushed to move horizontally along the track of the first guiding groove 5. After moving to the appropriate position, by releasing the pulling block 8, the pulling force generated by the tension spring 43 will drive the pulling block 8 and the pin rod 9 to reset, so that the pin rod 9 enters the corresponding pin hole 10 inside, and the first guiding block 6 is restricted again, completing the horizontal adjustment of the position of the suspension rod 3.

[0068] After that, by screwing the two threaded rods 15 on both sides of the second guiding block 11, the threaded rods 15 will move upward, and at the same time drive the traction block 17 and the limiting rod 19 to move upward. When the limiting rod 19 leaves the inside of the limiting hole 20, at this time, the second guiding block 11, the support beam 4, the suspension rod 3 and other structures can be driven to move longitudinally. After reaching the appropriate position, screwing the threaded rods 15 in the reverse direction can make the threaded rods 15 move downward, and at the same time drive the traction block 17 and the limiting rod 19 to move downward and enter the corresponding limiting hole 20 inside, completing the longitudinal adjustment of the suspension rod 3.

[0069] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
