Description

Technical Field

[0001] This utility model relates to the field of metal ceiling technology, and in particular to curved metal ceilings. Background Technology

[0002] A suspended ceiling refers to the decoration of the top of a living space. Simply put, it refers to the decoration of the ceiling and is an important part of interior decoration. Suspended ceilings serve functions such as heat insulation, sound insulation, and sound absorption, and also conceal electrical, ventilation, air conditioning, communication, fire protection, and alarm wiring and equipment. Appropriate decoration of the ceiling can not only beautify the interior environment but also create a rich and varied artistic image for the interior space. The main raw materials for metal suspended ceilings are aluminum-manganese alloy or aluminum-magnesium alloy.

[0003] Chinese utility model patent CN218843495U discloses a metal ceiling installation device, belonging to the field of decorative ceiling technology. It includes a ceiling keel, with left and right distributed hangers fixedly connected to the bottom end of the keel. A first bracket is sleeved on the top of the outer wall of the left hanger, and a first nut threadedly connected to the hanger is provided on the upper surface of the first bracket. A connecting rod is fixedly connected to the bottom right side of the first bracket, and a first sliding plate is fixedly connected to the bottom end of the connecting rod. A second bracket, located below the first bracket, is sleeved on the outer wall of the left hanger, and a second nut threadedly connected to the hanger is provided on the upper surface of the second bracket. First, two hangers are fixedly connected inside the ceiling keel. The first bracket is placed inside the second fixed frame, thus fixing the left side of the curved metal ceiling body. Then, a third bracket, sleeved on the outer wall of the right hanger, is placed inside the first fixed frame, also fixing the right side of the curved metal ceiling body.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the device fixes the first bracket with the first nut, the second bracket with the second nut, and the third bracket with the third nut. In actual use, the operator needs to lift the curved metal ceiling body to maintain stability and connect the three nuts to the three brackets in sequence. This makes it difficult for a single person to operate and results in a poor user experience. Utility Model Content

[0005] To solve the above problems, this utility model provides a curved metal ceiling.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a curved metal ceiling, including a ceiling keel, two hangers set on the bottom surface of the ceiling keel, a first bracket and a second bracket set on one of the hangers, a third bracket set on the other hanger, a first fixed frame connected to the third bracket, a fourth fixed frame connected to the second bracket, and a curved metal ceiling body jointly installed on the first fixed frame and the fourth fixed frame. The upper surface of the curved metal ceiling body is threaded with a threaded rod, and the ceiling keel is provided with a limiting component for limiting the threaded rod.

[0007] Furthermore, the limiting assembly includes a sleeve rod rotatably mounted on the upper end of the threaded rod, a sleeve slidably connected to the sleeve rod, and a limiting device mounted on the sleeve rod for limiting the sleeve rod. The upper end of the sleeve rod is fixed to the ceiling joist.

[0008] By adopting the above technical solution, when workers need to install curved metal ceiling panels, they only need to connect the threaded rod to the upper end of the curved metal ceiling panel body to keep the sleeve rod stable. At this time, workers can adjust the angle of the sleeve rod by rotating it. Furthermore, workers only need to lift the curved metal ceiling panel body upwards to connect the sleeve rod to the sleeve, thereby limiting the sleeve rod with a limiting device. At this time, workers only need to release the curved metal ceiling panel body to keep it stable under the action of the limiting device, thus reducing the difficulty of adjusting the height of the curved metal ceiling panel body. Subsequently, after the curved metal ceiling panel body is moved to the appropriate height, workers only need to use nuts and other tools to fix the curved metal ceiling panel body, thus reducing the difficulty of installing the curved metal ceiling panel body.

[0009] Furthermore, a first rotating groove is formed on the bottom surface of the sleeve rod, and a second rotating groove is formed on the inner wall of the first rotating groove. A rotating block is rotatably arranged in the second rotating groove, and the bottom surface of the rotating block is fixed to the upper surface of the threaded rod.

[0010] Furthermore, a sliding groove is formed on the inner wall of the sleeve, and a moving groove is formed on the side wall of the sleeve rod. The limiting device includes a sliding plate that is slidably disposed in the sliding groove, a plurality of fixed blocks that are equally spaced on the sliding plate near the side wall of the sleeve rod, a moving rod that is slidably disposed in the moving groove, a return spring that is fixed at one end to the side wall of the moving rod away from the fixed block, and a compression spring that is fixed at one end to the side wall of the sliding plate away from the fixed block. The other end of the compression spring is fixed to the inner wall of the sliding groove away from the sleeve rod, and the other end of the return spring is fixed to the inner wall of the moving groove.

[0011] Furthermore, a first inclined surface is formed on the edge where the bottom surface of the fixing block intersects with the side wall near the sleeve rod, and a second inclined surface is formed on the edge where the side wall away from the sleeve rod intersects with its upper surface.

[0012] By adopting the above technical solution, when workers need to install the curved metal ceiling body, they need to connect the threaded rod to the upper end of the curved metal ceiling body and move the curved metal ceiling body upwards, thus connecting the sleeve rod and the sleeve. During this process, the moving rod moves completely into the moving groove under the combined action of the sleeve and the second inclined surface. Subsequently, when the moving rod is aligned with the sliding groove, one end of the moving rod moves into the sliding groove, thereby pressing the moving rod against the fixing block. At this time, the workers only need to loosen the curved metal ceiling body, allowing it to move slightly downwards under gravity, causing one of the fixing blocks to block the moving rod, thus stabilizing the moving rod and the sliding rod. Workers do not need to continuously apply a force to the sleeve rod to maintain stability, thereby reducing the difficulty of installing the curved metal ceiling body.

[0013] Furthermore, a connecting rope is fixed to the side wall of the slide away from the fixed block, and the other end of the connecting rope extends to the outside of the sleeve and is slidably connected.

[0014] Furthermore, a sliding groove is provided on the side wall of the sleeve, and a sliding block is slidably disposed in the sliding groove. The upper surface of the sliding block is fixed to the connecting rope.

[0015] By adopting the above technical solution, when workers need to adjust the position of the curved metal ceiling body downwards, they need to separate the fixed block from the moving rod. At this time, workers need to slide the sliding block downwards, so that the connecting rope moves downwards under the action of the sliding block, and then the sliding plate moves away from the moving rod under the action of the moving rope, thereby separating the fixed block from the moving rod, and then allowing the curved metal ceiling body to move downwards under the action of gravity.

[0016] Furthermore, a support spring is fixed to the bottom surface of the sliding block, and the other end of the support spring is fixed to the inner bottom wall of the sliding groove.

[0017] By adopting the above technical solution, when the sliding block is subjected to external force, the sliding block presses against the inner top wall of the sliding groove under the action of the support spring, thereby keeping the sliding block stable and reducing the probability of the sliding block interfering with the normal operation of the slide plate at this time.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this application, when workers need to install a curved metal ceiling, they need to connect the threaded rod to the upper end of the curved metal ceiling body to stabilize the sleeve. At this time, workers can adjust the angle of the sleeve by rotating it. Furthermore, workers only need to lift the curved metal ceiling body upwards to connect the sleeve and the sleeve, thereby limiting the sleeve with a limiting device. Then, workers only need to loosen the curved metal ceiling body to keep it stable under the action of the limiting device, thus reducing the difficulty of adjusting the height of the curved metal ceiling body. Subsequently, after the curved metal ceiling body has moved to the appropriate height, workers only need to use nuts or other tools to fix it, thus reducing the difficulty of installing the curved metal ceiling body.

[0020] 2. In this application, when workers need to install the curved metal ceiling body, they need to connect the threaded rod to the upper end of the curved metal ceiling body and move the curved metal ceiling body upwards, thus connecting the sleeve rod and the sleeve. During this process, the moving rod moves completely into the moving groove under the combined action of the sleeve and the second inclined surface. Subsequently, when the moving rod is aligned with the sliding groove, one end of the moving rod moves into the sliding groove, thereby pressing the moving rod against the fixing block. At this time, the workers only need to loosen the curved metal ceiling body, allowing it to move slightly downwards under gravity, causing one of the fixing blocks to block the moving rod, thus stabilizing the moving rod and the sliding rod. Workers do not need to continuously apply a force to the sleeve rod to maintain stability, thereby reducing the difficulty of installing the curved metal ceiling body.

[0021] 3. In this application, when the worker needs to adjust the position of the curved metal ceiling body downwards, the worker needs to separate the fixed block from the moving rod. At this time, the worker needs to slide the sliding block downwards, so that the connecting rope moves downwards under the action of the sliding block, and then the sliding plate moves away from the moving rod under the action of the moving rope, so that the fixed block and the moving rod separate from each other, and then the curved metal ceiling body moves downwards under the action of gravity.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-4 As shown in the illustration, this application discloses a curved metal ceiling, including a ceiling joist 1, hangers 11, a first bracket 2, a second bracket 21, a third bracket 3, a first fixing frame 31, a fourth fixing frame 4, a curved metal ceiling body 41, a threaded rod 5, a limiting component 6, a rotating block 82, a connecting rope 83, a sliding block 85, and a supporting spring 9. Two hangers 11 are provided and sequentially arranged on the bottom surface of the ceiling joist 1. The first bracket 2 and the second bracket 21 are each mounted on one of the hangers 11, and the third bracket 3 is mounted on the other hanger 11. The first fixing frame 31 and the third bracket 3 are interconnected, and the fourth fixing frame 4 is interconnected with the second bracket 21. The curved metal ceiling body 41 is mounted on both the first fixing frame 31 and the fourth fixing frame 4, and the lower end of the threaded rod 5 is threadedly connected to the upper surface of the curved metal ceiling body 41.

[0029] A limiting component 6 is installed on the ceiling joist 1 to limit the movement of the fixed rod. The limiting component 6 includes a sleeve rod 61, a sleeve 62, and a limiting device 7. The sleeve rod 61 is a rectangular rod structure that is rotatably mounted on the upper end of the threaded rod 5. The sleeve 62 is a rectangular rod structure with an open lower end. The sleeve 62 is slidably connected to the sleeve rod 61, and the upper end of the sleeve 62 is fixed to the ceiling joist 1.

[0030] A sliding groove 63 is formed on the inner wall of the sleeve 62, and a moving groove 64 is formed on the side wall of the sleeve rod 61. A limiting device 7 is provided on the sleeve 62 to limit the movement of the sleeve rod 61. The limiting device 7 includes a sliding plate 71, a fixing block 72, a moving rod 73, a return spring 74, and a compression spring 75. The sliding plate 71 is a rectangular plate structure and is slidably disposed in the sliding groove 63. The fixing block 72 is a rectangular block structure, and multiple fixing blocks 72 are provided and evenly distributed on the side wall of the sliding plate 71 near the sleeve rod 61. The moving rod 73 is a rectangular rod structure and is slidably disposed in the moving groove 64. One end of the return spring 74 is fixed to the side wall of the moving rod 73 away from the fixing block 72, and the other end of the return spring 74 is fixed to the inner wall of the moving groove 64. One end of the compression spring 75 is fixed to the side wall of the sliding plate 71 away from the fixing block 72, and the other end of the compression spring 75 is fixed to the inner wall of the sliding groove 63 away from the sleeve rod 61. A first inclined surface 76 is provided on the edge where the bottom surface of the fixed block 72 intersects with the side wall near the sleeve rod 61, and a second inclined surface 77 is provided on the edge where the side wall away from the sleeve rod 61 intersects with the upper surface of the moving rod 73.

[0031] When installing the curved metal ceiling body 41, the worker connects the threaded rod 5 to the upper end of the curved metal ceiling body 41 and moves the curved metal ceiling body 41 upwards, thus connecting the sleeve rod 61 and the sleeve 62. During this process, the moving rod 73 moves completely into the moving groove 64 under the combined action of the sleeve 62 and the second inclined surface 77. Subsequently, when the moving rod 73 is aligned with the sliding groove 63, one end of the moving rod 73 moves into the sliding groove 63, thereby pressing the moving rod 73 against the fixing block 72. At this point, the worker only needs to release the curved metal ceiling body 41, allowing it to move slightly downwards under gravity, thus causing one of the fixing blocks 72 to block the moving rod 73, thereby stabilizing the moving rod 73 and the sliding rod. The worker does not need to continuously apply a stabilizing force to the sleeve rod 61, thus reducing the difficulty of installing the curved metal ceiling body 41.

[0032] The bottom surface of the sleeve rod 61 is provided with a first rotating groove 8, and the inner wall of the first rotating groove 8 is provided with a second rotating groove 81. The rotating block 82 is a circular block structure. The rotating block 82 is rotatably disposed in the second rotating groove 81, and the bottom surface of the rotating block 82 is fixed to the upper surface of the threaded rod 5.

[0033] One end of the connecting rope 83 is fixed to the side wall of the slide plate 71 away from the fixed block 72, and the other end of the connecting rope 83 extends to the outside of the sleeve 62 and is slidably connected. A sliding groove 84 is provided on the side wall of the sleeve 62, and the sliding block 85 is a rectangular block structure. The sliding block 85 is slidably disposed in the sliding groove 84, and the upper surface of the sliding block 85 is fixed to the connecting rope 83.

[0034] When the worker needs to adjust the position of the curved metal ceiling body 41 downwards, the worker needs to separate the fixed block 72 from the moving rod 73. At this time, the worker needs to slide the sliding block 85 downwards, so that the connecting rope 83 moves downwards under the action of the sliding block 85, and then the sliding plate 71 moves away from the moving rod 73 under the action of the moving rope, so that the fixed block 72 separates from the moving rod 73, and then the curved metal ceiling body 41 moves downwards under the action of gravity.

[0035] One end of the support spring 9 is fixed to the bottom surface of the sliding block 85, and the other end of the support spring 9 is fixed to the inner bottom wall of the sliding groove 84. When the sliding block 85 is not subjected to external force, the sliding block 85 presses against the inner top wall of the sliding groove 84 under the action of the support spring 9, thereby keeping the sliding block 85 stable and reducing the probability that the sliding block 85 will interfere with the normal operation of the slide plate 71.

[0036] The working principle of the curved metal ceiling in this embodiment is as follows: When the worker needs to install the curved metal ceiling, the worker needs to connect the threaded rod 5 to the upper end of the curved metal ceiling body 41 to keep the sleeve rod 61 stable. At this time, the worker can adjust the angle of the sleeve rod 61 by rotating it. Further, the worker only needs to lift the curved metal ceiling body 41 upwards to connect the sleeve rod 61 to the sleeve 62, thereby limiting the sleeve rod 61 with the limiting device 7. At this time, the worker only needs to release the curved metal ceiling body 41 to keep it stable under the action of the limiting device 7, thereby reducing the difficulty of adjusting the height of the curved metal ceiling body 41. Subsequently, after the curved metal ceiling body 41 is moved to a suitable height, the worker only needs to use nuts and other tools to fix the curved metal ceiling body 41, thereby reducing the difficulty of installing the curved metal ceiling body 41.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
