Description

Technical Field

[0001] This application relates to the field of suspended ceiling structures, and more particularly to a suspended ceiling structure with adjustable height. Background Technology

[0002] Traditional suspended ceiling structures typically have a fixed height determined during installation. The distance between the ceiling panel and the ceiling is pre-designed and set during installation, and cannot be adjusted later. However, different rooms or spaces with different uses may require different ceiling heights. For example, a conference room might need a higher ceiling to provide a sense of spaciousness and good acoustics, while a home study might need a lower ceiling to create a warm atmosphere. Fixed-height ceilings cannot flexibly adapt to these needs.

[0003] Because the height cannot be adjusted, installers need to precisely measure and calculate when fixing the ceiling to ensure that the height meets design requirements. This increases the complexity and time cost of installation. During the renovation process, if the ceiling height needs to be adjusted according to actual conditions, the fixed ceiling structure often needs to be dismantled and reinstalled. This not only wastes materials but also increases labor costs and time. Different types of spaces have different requirements for ceiling height. For example, commercial spaces, residences, offices, and entertainment facilities have different needs for ceiling height and decorative style. Fixed-height ceilings are difficult to flexibly adapt to these changes. Over time, decoration styles and personal preferences may change. Fixed-height ceiling structures are difficult to adapt to such changes and may require large-scale renovations to achieve the new decorative effect.

[0004] Therefore, it is necessary to design a suspended ceiling structure that can flexibly adjust its height, which can effectively solve the inconvenience and limitations of the existing fixed-height suspended ceiling structure, meet the needs of different spaces and decoration styles, and improve the flexibility and practicality of decoration.

[0031] Embodiments of this application provide an adjustable-height suspended ceiling structure, comprising:

[0032] The support member has a rotating hole.

[0033] A rotating rod passes through the rotating hole and is rotatably connected to the rotating hole. The rotating rod has multiple clips and holes arranged around the rotating axis of the rotating rod.

[0034] A keel is provided with a suspension rope between the keel and the rotating rod. One end of the suspension rope is attached to the rotating rod, and the other end is attached to the keel. The suspension rope is wrapped around the rotating rod, and the suspension rope causes the keel to move closer to or away from the rotating rod.

[0035] The clips and posts are slidably connected to the support member, and correspond to the clips and holes. The clips and posts extend into the clips and holes to restrict the rotation of the rotating rod. The adjustable-height ceiling structure described above uses the rotation of the rotating rod to cause the suspension rope to wind around the rotating rod. The suspension rope drives the keel to rise or fall. The clips and posts engage with the clips and holes to restrict the rotation of the rotating rod, fixing the keel at a specified height. This effectively solves the inconvenience and limitations of existing fixed-height ceiling structures.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Please see Figures 1-5This application provides an adjustable-height ceiling structure 100, including a support member 1, a rotating rod 2, a keel 3, and clips and columns 8. The support member 1 has a rotating hole 11. The rotating rod 2 passes through the rotating hole 11 and is rotatably connected to it. The rotating rod 2 has multiple clips and holes 21 arranged around its rotation axis. A suspension rope 31 is provided between the keel 3 and the rotating rod 2. One end of the suspension rope 31 is attached to the rotating rod 2, and the other end is attached to the keel 3. The suspension rope 31 is wound around the rotating rod 2, causing the keel 3 to move closer to or away from the rotating rod 2. The clips and columns 8 are slidably connected to the support member 1, and correspond to the clips and holes 21. The clips and columns 8 extend into the clips and holes 21 to restrict the rotation of the rotating rod 2.

[0038] Specifically, the support member 1 is the foundation of the entire suspended ceiling structure, mainly used for fixing and supporting other components. The rotating hole 11 on it provides a position for the installation of the rotating rod 2, and also serves to stabilize the rotating rod 2. The support member 1 is installed on the ceiling as a fixed point. The rotating rod 2 is installed on the support member 1 through the rotating hole 11 and can rotate freely. The support member 1 is suitable for any location requiring a suspended ceiling, such as a conference room, home study, or office. The rotating rod 2 passes through the rotating hole 11 on the support member 1 and is rotatably connected to it. The rotating rod 2 has multiple clips and holes 21, which are used to fix clips and posts 8 to restrict the rotation of the rotating rod 2, thereby controlling the adjustment of the suspended ceiling height. When the rotating rod 2 rotates on the support member 1, the height of the suspended ceiling can be raised or lowered by winding and releasing the suspension rope 31. The clips and posts 8, by extending into the clips and holes 21 on the rotating rod 2, restrict the rotation of the rotating rod 2, allowing the suspended ceiling to be fixed at a set height. Suitable for locations requiring frequent ceiling height adjustments, such as multi-functional conference rooms, lecture halls, and classrooms. The keel 3 is the main load-bearing component of the ceiling structure, supporting the ceiling panels. Connected to the rotating rod 2 by a suspension rope 31, the height of the keel 3 can be adjusted. When the rotating rod 2 rotates, the suspension rope 31 winds or unwinds, causing the keel 3 to move up and down, thus adjusting the ceiling height. Suitable for locations requiring flexible ceiling height adjustments, such as theaters, exhibition halls, and temporary exhibition areas. The clips and posts 8 are slidably connected to the support member 1 and can extend into the clips and holes 21 on the rotating rod 2, restricting the rotation of the rotating rod 2 and ensuring that the ceiling will not descend due to gravity or other external forces when the set height is reached. The clips and posts 8 slide within the support member 1. When it is necessary to fix the rotating rod 2, the clips and posts 8 extend into the clips and holes 21 on the rotating rod 2, restricting its rotation. When releasing the fixation, the clips and posts 8 retract from the clips and holes 21, allowing the rotating rod 2 to rotate for height adjustment.

[0039] In a specific example, the support member 1 has a locking post hole 12 that communicates with the rotating hole 11. The length direction of the locking post hole 12 is perpendicular to the length direction of the rotating hole 11. The lock and post 8 are disposed in the locking post hole 12 and are slidably connected to the locking post hole 12.

[0040] Specifically, the locking pin hole 12 is a hole opened on the support member 1, and its length direction is perpendicular to the length direction of the rotating hole 11. This hole is used to accommodate and slide the locking pin 8 component. The locking pin hole 12 communicates with the rotating hole 11, meaning that the position and orientation of the locking pin hole 12 intersects or connects with the rotating hole 11, thus ensuring that the adjustment and positioning of the locking pin 8 will not affect the rotation function of the rotating rod 2. The length direction of the locking pin hole 12 is perpendicular to the length direction of the rotating hole 11, forming an intersecting layout. This vertical arrangement ensures that the operation between the locking pin hole 12 and the rotating hole 11 does not interfere with each other. This vertical arrangement helps to avoid interference between the two functional components (locking pin and rotating rod 2), so that the sliding adjustment in the locking pin hole 12 will not affect the rotation or position of the rotating rod 2, thereby achieving precise height adjustment and stable fixation. The locking pin 8 is a slidingly connected component placed in the locking pin hole 12. They are designed to slide along their length direction within the locking pin hole 12. The sliding connection between the locking pin 8 and the locking pin hole 12 allows the locking pin 8 to move back and forth within the hole. This design allows operators to adjust the position of the clips and posts 8 as needed. The sliding connection design ensures that the clips and posts 8 can move smoothly within the clip hole 12 without rotation or tilting, providing a stable adjustment effect. The operator slides the clips and posts 8 within the clip hole 12 to the desired position. This operation can change the relative position of the clips and posts 8, thus affecting their engagement with the clip hole 21 on the rotating rod 2. After sliding the clips and posts 8 to the target position, they will engage with the clip hole 21 on the rotating rod 2. In this way, the clips and posts 8 will restrict the rotation of the rotating rod 2, ensuring that the ceiling is stable at the set height. After the clips and posts 8 are inserted into the clip hole 21, they will restrict the rotation of the rotating rod 2, thereby fixing the height of the ceiling. The interconnected layout of the clip hole 12 and the rotating hole 11 ensures that this adjustment process does not interfere with other functions of the rotating rod 2.

[0041] In one specific example, the height-adjustable ceiling structure 100 also includes a first motor 4, which is connected to the rotating rod 2 in a transmission manner.

[0042] Specifically, this is an electromechanical device used to drive and control the rotation of the rotating rod 2 in the ceiling structure. The main function of the motor is to provide power so that the rotating rod 2 can rotate in a preset manner, thereby adjusting the ceiling height. This means that the first motor 4 is connected to the rotating rod 2 through some mechanism (such as gears, belts, etc.), so that the rotational motion of the motor can be transmitted to the rotating rod 2. In this way, the movement of the motor can directly affect the rotation of the rotating rod 2, thereby adjusting the ceiling height. The introduction of the first motor 4 automates the adjustment of the ceiling height. Users can adjust the ceiling height through the motor's control system (such as a switch, remote control, or intelligent control system) without manual operation. The motor can provide stable and controllable rotational power, making the rotation of the rotating rod 2 more precise. Through the control of the motor, fine-grained height adjustment can be achieved to meet the specific needs of different application scenarios.

[0043] In one specific example, the first motor 4 is equipped with a first gear 41, and the rotating rod 2 is equipped with a second gear 22. The first gear 41 and the second gear 22 are connected in a transmission relationship. The first motor 4 drives the first gear 41 to rotate, the first gear 41 drives the second gear 22 to rotate, and the second gear 22 drives the rotating rod 2 to rotate.

[0044] The radius R1 of the first gear 41 and the radius R2 of the second gear 22 satisfy the relationship: R1 > R2.

[0045] Specifically, rotational motion and power are transmitted through the meshing of gears. The rotation of one gear can drive the rotation of another gear. The radius and number of teeth of the gears determine the transmission ratio and the transmission of force. The transmission relationship between two gears is determined by the gear radius (or number of teeth). The transmission ratio determines the relationship between input and output speed and force. A first gear 41 is mounted on a first motor 4. The motor provides power by rotating the first gear 41. A second gear 22 is mounted on a rotating rod 2. The second gear 22 receives the rotational power from the first gear 41 through meshing, thereby driving the rotating rod 2 to rotate. This means that the first gear 41 and the second gear 22 mesh with each other, and the rotation of the first gear 41 drives the rotation of the second gear 22. The first motor 4 drives the first gear 41 to rotate. The rotation of the first gear 41, through meshing with the second gear 22, drives the second gear 22 to rotate. The rotation of the second gear 22 then drives the rotating rod 2 to rotate, thereby adjusting the height of the suspended ceiling. The radius R1 of the first gear 41 is greater than the radius R2 of the second gear 22. This relationship indicates that the first gear 41 is larger than the second gear 22. Based on the gear ratio (R1 / R2), when the radius of the first gear 41 is larger than that of the second gear 22, for every one revolution of the first gear 41, the second gear 22 will rotate more times than the first gear 41. In other words, the second gear 22 rotates at a higher speed. The larger first gear 41 converts a lower rotational speed into a larger torque, while the smaller second gear 22 outputs torque at a higher rotational speed. This design improves the torque output of the system, ensuring that the rotating rod 2 can rotate stably and efficiently.

[0046] In one specific example, the height-adjustable ceiling structure 100 further includes a second motor 5 mounted on the support member 1. The second motor 5 is connected to the lead screw of the clip and column 8. The second motor 5 pushes the clip and column 8 closer to or further away from the rotating column along the length direction of the clip hole 12.

[0047] Specifically,

[0048] The second motor 5 is mounted on the support 1 and is used to drive and control the movement of the clamp and post 8. The second motor 5 is connected to the clamp and post 8 via a lead screw. A lead screw is a commonly used mechanical transmission component that converts rotary motion into linear motion. The rotation of the motor drives the lead screw to rotate, thereby causing the components connected to the lead screw to move along the lead screw axis. The clamp and post 8 are slidably connected to the support 1 and move along the length direction of the clamp post hole 12. The position of the rotating rod 2 is adjusted. The clamp post hole 12 is a hole opened on the support 1, perpendicular to the rotating hole 11. It allows the clamp and post 8 to slide along its length direction within it. When the second motor 5 is started, it drives the linear movement of the clamp and post 8 through the rotation of the lead screw. The rotation of the motor is converted into the rotation of the lead screw, and the rotation of the lead screw drives the clamp and post 8 connected to it to move along the clamp post hole 12. The clamp and post 8 move along the length direction of the hole within the clamp post hole 12. This direction of movement is perpendicular to the rotation axis of the rotating rod 2, changing the position of the clamp and post 8 relative to the rotating rod 2. The movement of the latch and post 8 changes the alignment of the latch and hole 21, thereby affecting the rotation limit of the rotating rod 2. Specifically, the movement of the latch and post 8 can cause the latch and post 8 to re-enter or re-exit the latch and hole 21, thereby adjusting the rotation of the rotating rod 2.

[0049] In a specific example, a boss 121 is provided in the card post hole 12, and a guide groove 81 is provided on the card and post 8. The boss 121 matches the guide groove 81, and the boss 121 restricts the rotation of the card and post 8.

[0050] Specifically, the locking post hole 12 is a hole opened on the support member 1, allowing the locking post 8 to slide along its length. The boss 121 is a protruding component provided within the locking post hole 12, used to restrict the rotational movement of the locking post 8. The guide groove 81 is a groove-shaped structure provided on the locking post 8. It matches the boss 121 within the locking post hole 12, used to guide and restrict the rotation of the locking post 8. The locking post 8 slides within the locking post hole 12 and engages with the boss 121 and the guide groove 81. When the boss 121 within the locking post hole 12 engages with the guide groove 81 on the locking post 8, the boss 121 inserts into the guide groove 81. This engagement ensures the precise positioning of the locking post 8 within the locking post hole 12. The boss 121 ensures that the locking post 8 slides stably along a straight line under the rotation of the lead screw. This ensures that the rotation of the lead screw can be smoothly converted into the linear movement of the locking post 8, thereby achieving accurate height adjustment.

[0051] In one specific example, the height-adjustable ceiling structure 100 further includes a protective shell 6, which covers the support member 1, and the rotating rod 2 is located between the protective shell 6 and the support member 1.

[0052] Specifically, the main function of the protective housing 6 is to protect critical components inside the ceiling structure, such as the rotating rod 2 and the suspension rope 31, from the influence of the external environment. It prevents dust, dirt, moisture, or other factors that could damage the internal components from entering. By providing protection for these components, the protective housing 6 helps extend the service life of the ceiling structure and reduces maintenance frequency and repair costs.

[0053] In one specific example, the protective housing 6 is provided with a cable outlet 61, which connects the outside to the inside of the protective housing 6, and the suspension rope 31 passes through the cable outlet 61.

[0054] Specifically, the main function of the outlet 61 is to provide a channel for the suspension rope 31, allowing it to pass through the protective housing 6 and connect to the rotating rod 2 and the keel 3. The suspension rope 31 is used to adjust the ceiling height by winding around the rotating rod 2. After passing through the outlet 61, the suspension rope 31 can move freely during the rotation of the rotating rod 2, thus achieving ceiling height adjustment. The outlet 61 allows the suspension rope 31 to extend from inside the protective housing 6 to the outside, enabling external operators to directly adjust the ceiling height. This design simplifies operation and makes ceiling adjustment more convenient. It also facilitates the inspection and maintenance of the suspension rope 31 and its connection to the rotating rod 2. The operator can observe the status of the suspension rope 31 through the outlet 61 and make necessary adjustments or replacements.

[0055] In one specific example, the height-adjustable ceiling structure 100 further includes a fixing bolt 7, and the support member 1 has a screw hole 13, through which the fixing bolt 7 is connected to an external object.

[0056] Specifically, the main function of the fixing bolts 7 is to firmly fix the support components 1 of the ceiling structure to the building structure or other external objects. This fixing method ensures the stability of the ceiling during use, preventing its function and safety from being affected by movement or vibration. The fixing bolts 7 prevent the ceiling structure from loosening due to vibration, impact, or other external forces during long-term use. This helps maintain the long-term stability and safety of the ceiling.

[0057] In one specific example, the protective housing 6 is bolted to the support member 1.

[0058] Specifically, the protective housing 6 is an important component of the height-adjustable ceiling structure 100, and its main function is to protect the internal components. The protective housing 6 prevents dust, dirt, and other substances from entering the ceiling structure, thus protecting internal components such as the rotating rod 2, motor, and suspension rope 31, ensuring their normal operation. The protective housing 6 also prevents physical damage to the internal components from external objects, such as collisions or scratches. It prevents users or other personnel from directly contacting potentially moving parts or electrical components when touching the ceiling structure, thereby avoiding safety hazards such as electric shock or mechanical injury. The protective housing 6 is bolted to the support member 1 to ensure its stability and fixation. The bolted connection ensures that the protective housing 6 is firmly attached to the support member 1, preventing it from loosening or falling off during use. The bolted connection also facilitates the installation and removal of the protective housing 6. When maintenance or replacement of internal components is required, the protective housing 6 can be easily removed by loosening the bolts.

[0059] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
