Technical Field

[0001] The present invention relates to the technical field of building assembly, in particular to a multifunctional environmentally friendly suspended ceiling and an installation method thereof. Background Art

[0002] A suspended ceiling is a decorative feature of a building's living environment. It provides insulation, heat insulation, sound insulation, and sound absorption, and serves as a concealed layer for electrical, ventilation, air conditioning, communications, fire protection, and alarm systems. With the improvement of people's aesthetic standards and advances in building materials technology, the requirements for interior ceiling decoration are becoming increasingly diverse.

[0003] In the prior art, a Chinese patent with publication number CN111593840B discloses a multifunctional and environmentally friendly suspended ceiling and installation method. In the document, "the lower end of the hanger is connected to the keel frame by a fixing bolt, and the upper end of the hanger is connected to the ceiling by a fixing bolt." However, the fixing bolts are difficult to remove. When the hanger needs to be removed, most people use a cutting machine to directly cut it off, which makes the hanger difficult to recycle. In addition, the document states that "the torsion spring can rotate the base plate and drive it back to a horizontal state. The limit rod and the arc groove can cooperate to limit the rotation range of the rotating shaft and the base plate, and the base plate is positioned in a vertical state when the second clamping block is engaged with the second clamping groove." The deflection of the base plate is controlled by the method of "the base plate is flipped by the rotating shaft, and a 90° rotation space needs to be reserved, which has requirements for the floor height (the floor height requirement is ≥2.8m). In addition, the scalability of the ceiling installation function is insufficient and cannot meet the multi-scenario needs of smart buildings. Summary of the Invention

After the operation is completed, the reset spring one drives cylinder two to reset, maintaining the initial state of the clamping block one. The groove and the rectangular protrusion of the clamping block one form a nested structure to achieve mechanical interlocking.

The T-shaped rotating rod converts the manual operating force into mechanical movement, driving the clamping block to deflect. The clamping slot 1 provides a locking position for the T-shaped rotating rod to achieve state retention. The rubber pad absorbs vibration energy through deformation to prevent accidental unlocking.

[0013] Preferably, the fixing mechanism also includes a slide groove 2 opened on the opposite sides of keel 1 and keel 2, the clamping groove 2 is opened on the bottom surface of the slide groove 2, and both sides of the top plate are fixedly connected with a clamping block 2 that is adapted to be clamped with the clamping groove 2.

[0014] By adopting the above technical solution, the second slide groove provides a precise installation path for the top plate, ensuring that the second clamping block is aligned with the second clamping groove. The second clamping block and the second clamping groove form a rigid connection between the top plate and the keel, bearing the vertical load. The rectangular groove and the rotating plate 1 are mechanically linked to prevent the top plate from accidentally falling off, forming a double safety guarantee.

[0015] Preferably, one side of the rotating plate 1 is fixedly connected to a fixed block 1, and the side of the fixed block 1 away from the rotating plate 1 is rotatably connected to the rotating block 1, the inside of the rectangular groove is slidably connected to a washer, and the side of the rotating block 1 away from the fixed block 1 is fixedly connected to a soft rod slidably connected to the washer, and a return spring 2 sleeved on the surface of the soft rod is fixedly connected between the rotating block 1 and the washer, and a pull ring is fixedly connected to the side of the soft rod away from the rotating block 1, and the top surfaces of the keel 1 and keel 2 are fixedly connected to a fixed block 2 that is adapted to the pull ring.

The soft rod serves as a transmission medium for the operating force, connecting the pull ring and the rotating block 1. The reset spring 2 provides the reset driving force for the rotating plate 1 and maintains the daily locking state. The washer provides a linear motion track for the soft rod to eliminate radial offset. The pull ring serves as a manual operation interface to control the axial movement of the soft rod. The fixed block 2 provides a locking position for the pull ring to maintain the deflection state of the rotating plate 1.

[0017] Preferably, the auxiliary mechanism also includes a rotating plate 2 rotatably connected to the inside of the inspection port, the inspection port is opened inside the top plate, the inside of the inspection port is fixedly connected with a baffle abutting against the rotating plate 2, the side of the inspection port away from the baffle is symmetrically provided with a snap-in groove 3, the side of the rotating plate 2 close to the snap-in groove 3 is fixedly connected with a rotating circular plate abutting against the snap-in groove 3, and one side of the rotating circular plate is fixedly connected with a semicircular plate snap-fitted with the snap-in groove 3.

[0018] By adopting the above technical solution, the inspection port is used to maintain the internal equipment of the suspended ceiling. The rotating plate 2 serves as a movable cover of the inspection port to control the opening and closing of the channel. The baffle limits the maximum opening angle of the rotating plate 2 to prevent excessive rotation. The clamping groove 3 and the semicircular plate realize mechanical locking and unlocking of the inspection port through shape coupling. The rotating circular plate serves as an artificial force point to drive the semicircular plate to rotate.

[0019] The cam is fixedly provided with a toothed plate and a toothed plate, and the toothed plate is fixedly provided with a toothed plate and a toothed plate, and the toothed plate is fixedly provided with a toothed plate and a toothed plate, and the toothed plate is fixedly provided with a toothed plate and a toothed plate, and the toothed plate is fixedly provided with a toothed plate and a toothed plate, and the toothed plate is fixedly provided with a toothed plate and a toothed plate, and the toothed plate is fixedly provided with a toothed plate and a toothed plate,

[0020] By adopting the above technical solution, the slide groove three provides a two-way motion track for the slider one to realize the horizontal position adjustment of the mounting plate. The slider one serves as a motion carrier to connect the fixed plate one and the keel one. The fastening bolt locks the position of the slider one through friction to prevent displacement. The fixed plate one and the sliding plate one realize the length adjustment of the mounting plate through sliding cooperation. The buckle one is linearly arrayed on the sliding plate one to provide multi-gear fixing points. The connecting plate one is inserted between adjacent buckles one to realize mechanical locking. The auxiliary frame one provides a motion track for the connecting plate one to ensure the locking reliability. The pull rod one is the manual operation end to control the connecting plate one to disengage from the buckle one.

[0021] Preferably, the sliding plate 1 is fixedly connected to a connecting block 2 on a side away from the fixed plate 1, and the connecting block 2 is rotatably connected to the fixed plate 2 on a side away from the sliding plate 1. The interior of the fixed plate 2 is slidably connected to the sliding plate 2, and a linear array of several clips 2 are provided on one side of the sliding plate 2. The side of the fixed plate 2 close to the clips 2 is fixed and connected to an auxiliary frame 2, and the interior of the auxiliary frame 2 is slidably connected to a snap plate 2 that is clamped between adjacent clips 2, and the snap plate 2 is slidably connected to the interior of the fixed plate 2, and the snap plate 2 is fixedly connected to a pull rod 2 that passes through and is slidably connected to the auxiliary frame 2 on a side away from the sliding plate 2, and a reset spring 4 is fixedly connected between the snap plate 2 and the auxiliary frame 2, and the sliding plate 2 is rotatably connected to the mounting plate on a side away from the fixed plate 2.

[0022] By adopting the above technical solution, the connecting block 2 provides the mounting plate with rotational freedom to adapt to different installation angle requirements.

The snap plate 2 is inserted between adjacent clips 2 to achieve mechanical locking. The auxiliary frame 2 provides a motion track for the snap plate 2 to ensure locking reliability. The pull rod 2: manual operation end, controls the snap plate 2 to disengage from the clip 2. The reset spring 4 drives the snap plate 2 to automatically reset after the operation is completed and restore the locked state. The mounting plate serves as an equipment installation platform to support the integration of modules such as lamps, sensors, and pipelines.

[0023] The ceiling installation method includes the following steps: S1: Install the boom, insert the connecting block 1 into the interior of the cylinder 2, and make the connecting block 1 meet the connecting plate. Then, the worker holds the T-shaped rotating rod and controls it to move downward. When the T-shaped rotating rod moves downward, it drives the cylinder 2 downward together, thereby controlling the clamping block 1 to deflect inward, and clamping the connecting block 1 through the clamping block pair. After clamping the connecting block 1, control the T-shaped rotating rod to slide into the interior of the clamping slot 1 to fix the T-shaped rotating rod; S2: Install the keel. After the second cylinder is fixed, fix the auxiliary plate on the top surface of the first and second keels. The first and second keels can be inserted into the inside of the T-shaped slide groove through the T-shaped slider to achieve end-to-end splicing. The rotation of the first cylinder controls the up and down movement of the threaded rod, thereby adjusting the height of the first and second keels. S3: Install the top plate. After the installation of keel one and keel two is completed, install the top plate between keel one and keel two. When installing the top plate, slide the side of the top plate inside the slide groove two, and then slide the top plate so that the clamping block two is clamped inside the clamping groove two. When the clamping block two slides, it will push the rotating plate one to deflect. When the clamping block two is clamped into the clamping groove two, the rotating plate one returns to its original state and is on the top surface of the top plate.

[0024] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The threaded rod and the cylinder structure are used to realize stepless adjustment of the keel height by rotating the cylinder. Compared with the comparative documents which rely on fixed suspension rods and bolt connections, the height adjustment needs to be disassembled and reassembled, which is less efficient. In the present invention, the deflection of the clamping block 1 is controlled by the movement of the T-shaped rotating rod, and the clamping block 1 can be clamped on the edge protrusion of the connecting block 1, thereby fixing the suspension rod. When dismantling, it is only necessary to control the movement of the T-shaped rotating rod to cancel the clamping of the connecting block 1. The operation is convenient, and the suspension rod will not be damaged, and it is easy to recycle.

[0025] 2. With the top panel's built-in downward-opening rotating plate, maintenance only requires rotating the circular plate. The semicircular plate, which secures the three snap-in slots, can then be controlled to open downward without requiring additional space. This makes operation much easier than with comparable documents. Furthermore, when closed, the rotating plate sits flush with the top panel, leaving no exposed gaps or handles. This maintains the integrity of the ceiling, making it suitable for high-end commercial spaces (such as hotels and clubs) or minimalist decor. The secure connection between the semicircular plate and the snap-in slot prevents accidental opening.

[0026] 3. Through the setting of the mounting plate, wireless AP, sensors, and lamps can be integrated on the mounting plate for integrated installation to meet the needs of scenarios such as smart office and industrial monitoring. The distance of the mounting plates can be controlled by sliding the sliding plate 1 inside the fixed plate 1. The mounting plate can slide freely on the top plate by sliding the slider 1 in the slide groove 4. As a result, the mounting plate can be freely moved on the top plate, breaking the limitations of traditional fixed installation methods. Users can adjust the position of the mounting plate arbitrarily within the plane according to actual needs, further improving the flexibility of installation. BRIEF DESCRIPTION OF THE DRAWINGS

When the rotating circular plate 84 drives the semicircular plate 86 to rotate, it is necessary to overcome the built-in torque damping to ensure that the inspection port 81 stays firmly after opening to avoid accidental opening due to gravity or vibration. Two circular holes 85 are symmetrically provided on the side of the rotating circular plate 84 away from the semicircular plate 86. When the semicircular plate 86 is in a horizontal state, it cannot be clamped in the inside of the clamping groove 3 87. At this time, the rotating plate 2 82 can be controlled to open. When the semicircular plate 86 is in a vertical state, the semicircular plate 86 can be clamped in the inside of the clamping groove 3 87. At this time, the rotating plate 2 82 cannot be opened.

[0042] In the initial state, the rotating plate 82 is in a closed state and cannot be opened. When it needs to be opened, by rotating the rotating circular plate 84, the semicircular plate 86 fixedly connected to the rotating circular plate 84 is driven to rotate together, and the semicircular plate 86 is rotated to a horizontal state, so that the semicircular plate 86 cannot be clamped in the inside of the clamping groove 3 87, and the rotating plate 82 can be opened downward. Compared with the comparative document, the operation is convenient. In addition, when the rotating plate 82 is closed, it is flush with the top plate 3, without exposed gaps or handles, maintaining the integrity of the ceiling, and is suitable for high-end commercial spaces (such as hotels, clubs) or minimalist style decoration.

The movement of the pull rod 910 drives the clamping plate 99 fixedly connected to the pull rod 910 to move, thereby canceling the restriction on the buckle 97, so that the sliding plate 96 can move. When the clamping plate 99 moves, the return spring 3 911 is squeezed, so that the return spring 3 911 is compressed. When the position of the sliding plate 96 moves to the appropriate position, the pull rod 910 is released, and the squeezed return spring 3 911 is released, and the clamping plate 99 is driven to be inserted between two adjacent buckles 97 to limit the sliding plate 96.

[0050] When it is necessary to adjust the length of the sliding plate 2 914, the pull rod 2 919 is moved away from the auxiliary frame 2 917. The movement of the pull rod 2 919 drives the clamping plate 2 918 fixedly connected to the pull rod 2 919 to move together, thereby canceling the restriction on the buckle 2 916, so that the sliding plate 2 914 can move.

[0052] Example 2 The ceiling installation method includes the following steps: S1: Install the boom, insert the connecting block 1 612 into the interior of the cylinder 2 65, and make the connecting block 1 612 meet the connecting plate 611. Then, the staff holds the T-shaped rotating rod 613 and controls the T-shaped rotating rod 613 to move downward. When the T-shaped rotating rod 613 moves downward, it will drive the cylinder 2 69 to move downward together, thereby controlling the clamping block 1 610 to deflect inward, and clamping the connecting block 1 612 through the clamping block 1 610. After clamping the connecting block 1 612, control the T-shaped rotating rod 613 to slide into the interior of the clamping slot 1 615 to fix the T-shaped rotating rod 613; S2: Install the keel. After the second cylinder 65 is fixed, the auxiliary plate 61 is fixed to the top surface of the first keel 1 and the second keel 2. The first keel 1 and the second keel 2 can be inserted into the T-shaped slide 4 through the T-shaped slider 5 to achieve end-to-end splicing. The threaded rod 62 is controlled to move up and down by rotating the first cylinder 63, thereby adjusting the height of the first keel 1 and the second keel 2. S3: Install the top plate 3. After the installation of keel 1 and keel 2 is completed, install the top plate 3 between keel 1 and keel 2. When installing the top plate 3, slide the side of the top plate 3 inside the slide groove 2 71, and then slide the top plate 3 so that the clamping block 2 73 is clamped inside the clamping groove 2 72. When the clamping block 2 73 slides, it will push the rotating plate 1 75 to deflect. When the clamping block 2 73 is clamped into the clamping groove 2 72, the rotating plate 1 75 returns to its original state and is on the top surface of the top plate 3.

[0053] The implementation principle of a multifunctional environmentally friendly suspended ceiling and installation method according to an embodiment of the present invention is as follows: When in use, the T-shaped slider 5 is inserted into the interior of the T-shaped slide groove 4, thereby splicing the keel 1 and the keel 2 2 end to end to achieve the installation of the keel. After the auxiliary plate 61 is connected to the keel 1 and the keel 2 by the fixing bolts, the height of the keel 1 and the keel 2 can be adjusted by rotating the cylinder 1 63. Then, the cylinder 2 65 is plugged into the connecting block 1 612, and the connecting block 1 612 is abutted against the connecting plate 611. Then, the T-shaped rotating rod 613 is controlled to move, thereby driving the clamping block 1 610 to deflect, and then the clamping block 1 610 is clamped with the connecting block 1 612. Then, the T-shaped rotating rod 613 is controlled to rotate and clamped into the interior of the clamping groove 1 615 to keep the position of the cylinder 2 69 unchanged, thereby fixing the cylinder 2 65 to the connecting block 1 612, thereby achieving quick installation and disassembly, and no damage is caused to the boom during disassembly, which is convenient for recycling. During maintenance, by rotating the rotating circular plate 84, the semicircular plate 86 fixedly connected to the rotating circular plate 84 is driven to rotate together, and the semicircular plate 86 is rotated to a horizontal state so that the semicircular plate 86 cannot be clamped in the inner part of the clamping groove 3 87, and the rotating plate 2 82 can be opened downward; When adjusting the position of a device such as a wireless AP, when adjusting the length of the sliding plate 1 96 , the pull rod 1 910 is moved outward. The movement of the pull rod 1 910 drives the clamping plate 1 99 to move together, thereby removing the restriction on the buckle 1 97 and allowing the sliding plate 1 96 to move. When the sliding plate 1 96 moves to the appropriate position, the pull rod 1 910 is released, and the compressed return spring 3 911 is released, driving the clamping plate 1 99 to be inserted between two adjacent buckles 1 97 , limiting the position of the sliding plate 1 96 , and adjusting the rotation direction through the shaft damping provided at the connection; When the top plate needs to be disassembled, open the rotating plate 2 82, then hold the pull ring 711 and pull the soft rod 710 to move. The movement of the soft rod 710 drives the rotating block 1 77 and the fixed block 1 76 to move, and then drives the rotating plate 1 75 to move toward the fixed block 2 712. Then, the pull ring 711 is put on the fixed block 2 712 to remove the restriction on the top plate 3, so that the top plate 3 can be disassembled.
