Description

Technical Field

[0001] This invention relates to the field of ceiling technology, specifically to an installation component for an insulated ceiling panel. Background Technology

[0002] A suspended ceiling is a decorative and functional structure on the top of an interior space. It uses a support system such as a keel to fix decorative panels to the ceiling, concealing unsightly parts of the original ceiling surface such as pipes and structures, improving the overall aesthetics and cleanliness of the space. It can also be combined with lighting design to create rich light and shadow effects, enhancing the interior atmosphere. In addition, some suspended ceilings also have practical functions such as heat insulation, thermal insulation, sound insulation, and sound absorption, meeting the environmental comfort needs of different spaces. Among these, using foamed concrete insulation boards as a suspended ceiling material has significant advantages. It has excellent heat insulation, reducing heat transfer and energy consumption, aligning with green energy-saving concepts; its lightweight nature does not add burden to the ceiling structure, ensuring the safety and stability of the building.

[0003] In existing technologies, after the construction workers complete the installation of the main and secondary keels, the operation of installing the insulation board onto the secondary keel is quite cumbersome. The insulation board must first be pressed onto the secondary keel, and then self-tapping screws must be driven in for fixation. The whole process is time-consuming and labor-intensive. To address this, we propose an installation component for insulation board ceilings. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides an installation assembly for an insulated ceiling panel, including a main keel and secondary keels mounted on the main keel, as well as an insulation panel mounted on the secondary keel. The insulation panel has hollow connecting columns, and a connecting piece is provided between the main keel and the secondary keel. When the main keel and the secondary keel are installed and connected in place, the connecting piece can simultaneously fix the secondary keel. A locking column is retractably provided within the secondary keel. During the installation of the secondary keel to the main keel, when the secondary keel is in place, the locking column extends out of the secondary keel to engage with the hollow connecting column to secure the insulation panel.

[0005] In some embodiments, the docking member includes a hollow tube fixedly connected to the secondary keel, a magnet is slidably connected inside the hollow tube, and the contact surface between the main keel and the secondary keel is made of iron to temporarily fix the secondary keel in conjunction with the magnet. A rectangular groove is provided on the main keel. A sliding column is fixedly connected to one side of the magnet. One end of the sliding column slides through the hollow tube and is fitted with a tension spring. The two ends of the tension spring are fixed to the sliding column and the inner wall of the secondary keel, respectively. A connecting plate is fixedly connected to the sliding column. A rectangular connecting block is slidably connected to the secondary keel. A sliding rod is fixedly connected to one end of the rectangular connecting block. One end of the sliding rod slides through the connecting plate, and a spring is fitted on the sliding rod with its two ends fixed to the connecting plate and the rectangular connecting block, respectively. When the main keel and the secondary keel are installed together, the magnet attracts the main keel and drives the rectangular connecting block to insert into the rectangular groove. Furthermore, an L-shaped insert plate is slidably connected inside the main keel, and a T-shaped limiting plate is slidably connected inside the rectangular groove. A locking element is provided at one end of the T-shaped limiting plate to lock the L-shaped insert plate. When the rectangular connecting block is inserted into the rectangular groove, the T-shaped limiting plate is pushed and the locking element is released, so that the L-shaped insert plate extends out of the main keel and is inserted into the secondary keel.

[0006] In some embodiments, a slider is provided inside the main keel, a pull rod is fixedly connected to one side of the slider, a sleeve is fixedly connected to the inner wall of the main keel, one end of the pull rod passes through the sleeve, and a tension spring is sleeved on the pull rod with its two ends fixed to the sleeve and the slider respectively. A guide rod is fixedly connected to one end of the L-shaped insert plate. One end of the guide rod slides through the slider and is fixedly connected to a sliding column. A straight guide groove is provided on the inner wall of the main keel. One end of the sliding column is located in the straight guide groove and is slidably connected to its inner wall. An oblique guide groove communicating with the straight guide groove is provided on the inner wall of the main keel. A rectangular slot is provided on the secondary keel for use with an L-shaped insert plate to fix the secondary keel.

[0007] In some embodiments, the locking element one includes a top rod fixedly connected to one side of the slider, a rectangular body fixedly connected to one end of the T-shaped limiting plate, a circular groove on the rectangular body, and the edge of the circular groove is designed with a bevel. One end of the top rod is designed with an arc shape. When one end of the top rod is located in the circular groove, the L-shaped insert is in a locked state. At this time, the tension spring two is in a stretched state. A through hole is provided on the rectangular body to push the T-shaped limiting plate to move when the rectangular connecting block is inserted into the rectangular groove, and to align the through hole with the top rod to unlock the L-shaped insert plate.

[0008] In some embodiments, a slot is formed inside the hollow connecting column, and two locking blocks are symmetrically slidably connected to one end of the locking column. One end of each locking block is designed with an inclined surface, and the two locking blocks are located inside the locking column and are fixedly connected with a spring piece.

[0009] In some embodiments, multiple locking posts are provided on the secondary keel, and the multiple locking posts are evenly divided into multiple groups. Each group of locking posts corresponds to a magnet. A connecting rod is fixedly connected between each group of locking posts, and a second spring is fixedly connected to the locking post in each group that is away from the magnet. One end of the second spring contacts and abuts against the inner wall of the secondary keel. A second locking element is provided in the secondary keel for locking the locking posts. After the L-shaped insert plate is inserted into the rectangular slot, the locking element releases the locking post from the locking post.

[0010] In some embodiments, the second locking member includes an annular groove formed on the locking posts located on both sides of the magnet. A shaft is rotatably connected inside the secondary keel. A deflection hook is fixedly connected to the shaft, and a torsion spring is sleeved on the shaft with both ends fixedly connected to the shaft and the secondary keel, respectively. When one end of the deflection hook is located in the annular groove, the locking post is locked. When the L-shaped insert is inserted into the rectangular slot, one end of the deflection hook is pushed to drive the hook body of the deflection hook out of the annular groove.

[0011] In some embodiments, a rotating column is fixedly connected to one end of the hollow connecting column, one end of the rotating column passes through the insulation board, and a cross groove is provided on the rotating column. An inclined groove communicating with the slot is provided inside the hollow connecting column. When the rotating column is rotated, the hollow connecting column is driven to rotate, so as to push the locking block with the inclined groove.

[0012] This invention has at least the following beneficial effects: 1. This device, during ceiling installation, uses magnets to attract the main keel, enabling quick temporary fixation of the secondary keel. Furthermore, the secondary keel can only be fully fixed when it is precisely aligned with the designated position of the main keel. Simultaneously, the locking posts for securing the insulation board extend fully. Subsequent installation of the insulation board simply requires aligning the hollow connecting post on the insulation board with the locking post and inserting it, easily completing the installation. The entire process is simple and convenient, greatly improving installation efficiency.

[0013] 2. When the device is in transit, the L-shaped insert plate on the main keel is retracted inside, and the locking pin on the secondary keel is also retracted inside, effectively preventing damage to the connecting parts during transit. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-8 The present invention provides a technical solution: an installation assembly for a thermal insulation board ceiling, comprising a main keel 1 and a secondary keel 11 disposed on the main keel 1, and further comprising: Insulation board 2 is installed on the secondary keel 11, and hollow connecting column 3 is provided on the insulation board 2; The connecting piece 4 is installed on the main keel 1. When the main keel 1 and the secondary keel 11 are installed and connected in place, the connecting piece 4 can simultaneously fix the secondary keel 11. Locking post 5 is telescopically installed inside the secondary keel 11. During the process of installing the secondary keel 11 to the main keel 1, when the secondary keel 11 is installed in place, the locking post 5 extends out of the secondary keel 11 to cooperate with the hollow connecting post 3 to snap the insulation board 2. Specifically, during ceiling installation, the main keel 1 is attracted by magnet 42, which can quickly and temporarily fix the secondary keel 11. Furthermore, the secondary keel 11 can only be fully fixed when it is precisely aligned with the set position of the main keel 1. Simultaneously, the locking post 5 used to fix the insulation board 2 extends fully. When installing the insulation board 2, simply align the hollow connecting post 3 on the insulation board 2 with the locking post 5 and insert it to easily complete the installation. The entire process is simple and convenient, greatly improving installation efficiency. Meanwhile, during the device transfer process, the L-shaped insert plate 51 on the main keel 1 is retracted inside, and the locking pin 5 on the secondary keel 11 is also retracted inside, effectively preventing damage to the connecting parts during the transfer process.

[0018] The connecting piece 4 includes a hollow tube 41 fixedly connected to the secondary keel 11. A magnet 42 is slidably connected inside the hollow tube 41. The contact surface between the main keel 1 and the secondary keel 11 is made of iron, which is used to temporarily fix the secondary keel 11 in conjunction with the magnet 42. Specifically, after the construction personnel have installed the main keel 1, they can lift the secondary keel 11 and directly use the magnet 42 to attract the main keel 1 to temporarily fix the secondary keel 11. Subsequently, the construction personnel can easily move the secondary keel 11 to completely connect the secondary keel 11 to the main keel 1. A rectangular groove 43 is provided on the main keel 1. A sliding column 44 is fixedly connected to one side of the magnet 42. One end of the sliding column 44 slides through the hollow tube 41 and is fitted with a tension spring 45. The two ends of the tension spring 45 are fixedly connected to the sliding column 44 and the inner wall of the secondary keel 11, respectively. After the secondary keel 11 and the main keel 1 are connected, the magnet 42 attracts the main keel 1, which drives the sliding column 44 to move. At the same time, the tension spring 45 is stretched under force to provide self-recovery force. A connecting plate 46 is fixedly connected to the sliding column 44, and a rectangular connecting block 47 is slidably connected to the secondary keel 11. A sliding rod 48 is fixedly connected to one end of the rectangular connecting block 47. One end of the sliding rod 48 slides through the connecting plate 46, and a spring 49 is sleeved on the sliding rod 48, with its two ends fixed to the connecting plate 46 and the rectangular connecting block 47 respectively. Specifically, when the main keel 1 and the secondary keel 11 are connected and installed, there are two situations. One is that if the rectangular connecting block 47 is aligned with the rectangular groove 43, then the magnet 42 will attract the main keel 1 and drive the rectangular connecting block 47 to be inserted into the rectangular groove 43 at the same time, thereby completing the connection between the secondary keel 11 and the main keel 1. In another scenario, if the rectangular connecting block 47 is not aligned with the rectangular groove 43, the magnet 42 will attract the main keel 1 and move the connecting plate 46, compressing the spring 49. Subsequently, the staff will adjust the position of the secondary keel 11 until the rectangular connecting block 47 is aligned with the rectangular groove 43. Then, the spring 49 will reset and cause the rectangular connecting block 47 to be inserted into the rectangular groove 43.

[0019] Furthermore, an L-shaped insert plate 51 is slidably connected inside the main keel 1, and a T-shaped limiting plate 52 is slidably connected inside the rectangular groove 43. A locking element 53 is provided at one end of the T-shaped limiting plate 52 to lock the L-shaped insert plate 51. When the rectangular connecting block 47 is inserted into the rectangular groove 43, the T-shaped limiting plate 52 is pushed and the locking element 53 is released, so that the L-shaped insert plate 51 extends out of the main keel 1 and is inserted into the secondary keel 11, thereby completely completing the installation and locking of the secondary keel 11 and the main keel 1.

[0020] A slider 54 is provided inside the main keel 1. A pull rod 55 is fixedly connected to one side of the slider 54. A sleeve 56 is fixedly connected to the inner wall of the main keel 1. One end of the pull rod 55 slides through the sleeve 56, and a second tension spring 57 with both ends fixed to the sleeve 56 and the slider 54 respectively is sleeved on the pull rod 55. A guide rod 58 is fixedly connected to one end of the L-shaped insert plate 51. One end of the guide rod 58 slides through the slider 54 and is fixedly connected to a sliding column 59. A straight guide groove 61 is provided on the inner wall of the main keel 1. One end of the sliding column 59 is located in the straight guide groove 61 and is slidably connected to its inner wall. An oblique guide groove 62 communicating with the straight guide groove 61 is provided on the inner wall of the main keel 1. Furthermore, a rectangular slot 63 is provided on the secondary keel 11 for use with the L-shaped insert plate 51 to fix the secondary keel 11.

[0021] Locking component 53 includes a push rod 64 fixedly connected to one side of the slider 54. A rectangular body 65 is fixedly connected to one end of the T-shaped limiting plate 52. A circular groove 66 is provided on the rectangular body 65, and the edge of the circular groove 66 is designed with a bevel. One end of the push rod 64 is designed with an arc shape. When one end of the push rod 64 is located in the circular groove 66, the L-shaped insert plate 51 is in a locked state. At this time, the tension spring 57 is in a stretched state. A through hole 67 is provided on the rectangular body 65, which is used to push the T-shaped limiting plate 52 to move when the rectangular connecting block 47 is inserted into the rectangular groove 43, and to align the through hole 67 with the top rod 64 to unlock the L-shaped insert plate 51. Specifically, when the main keel 1 is not installed with the secondary keel 11, the T-shaped limiting plate 52 is located in the rectangular groove 43, and one end of the top rod 64 is located in the circular groove 66 on the rectangular body 65. At the same time, the tension spring 57 is in a stretched state, and the sliding column 59 is located in the inclined guide groove 62. Subsequently, after the main keel 1 is connected to the secondary keel 11, the rectangular connecting block 47 is inserted into the rectangular groove 43 and pushes the T-shaped limiting plate 52 to move, thereby driving the rectangular body 65 to move, so that the through hole 67 is aligned with the top rod 64, thereby releasing the lock of the slider 54. Then, the tension spring 57 resets and drives the slider 54 to move, thereby driving the sliding column 59 to slide along the inclined guide groove 62 first, and then along the straight guide groove 61, thereby driving the L-shaped insert plate 51 to first extend out of the main keel 1, and then move to insert into the rectangular slot 63 to lock the secondary keel 11.

[0022] A slot 68 is opened inside the hollow connecting column 3. Two locking blocks 69 are symmetrically slidably connected to one end of the locking column 5. One end of the locking blocks 69 is designed with a bevel. The two locking blocks 69 are located inside the locking column 5 and are fixedly connected with a spring piece 71. During the process of inserting the locking column 5 into the hollow connecting column 3, the hollow connecting column 3 first pushes the locking blocks 69 back into the locking column 5. At the same time, the spring piece 71 is compressed and deformed to provide self-recovering elasticity. Continue to insert the locking column 5. When the locking blocks 69 are aligned with the slot 68, the spring piece 71 resets and drives the locking blocks 69 to be embedded in the slot 68, thereby locking the insulation board 2.

[0023] Multiple locking pins 5 are provided on the secondary keel 11. The multiple locking pins 5 are evenly divided into multiple groups. Each group of locking pins 5 corresponds to a magnet 42. A connecting rod 72 is fixedly connected between each group of locking pins 5. A spring 73 is fixedly connected to the locking pin 5 in each group that is away from the magnet 42. One end of the spring 73 contacts and abuts against the inner wall of the secondary keel 11. A locking element 74 is provided in the secondary keel 11 to lock the locking pins 5. After the L-shaped insert plate 51 is inserted into the rectangular slot 63, the locking element 74 releases the locking pin 5.

[0024] Locking component 2 74 includes annular grooves 75 formed on locking posts 5 located on both sides of magnet 42. A shaft 76 is rotatably connected inside the secondary keel 11. A deflection hook 77 is fixedly connected to the shaft 76. A torsion spring 78 is sleeved on the shaft 76, with its two ends fixedly connected to the shaft 76 and the secondary keel 11 respectively. When one end of the deflection hook 77 is located in the annular groove 75, the locking post 5 is locked. When the L-shaped insert plate 51 is inserted into the rectangular slot 63, one end of the deflection hook 77 is pushed to disengage the deflection hook 77 from the annular groove 75. Specifically, when the secondary keel 11 is not installed, the locking pin 5 is located inside the secondary keel 11, and the spring 73 is in a compressed state. The deflection hook 77 is located in the annular groove 75 to lock the locking pin 5. Then, as soon as the L-shaped insert 51 is inserted into the rectangular slot 63, one end of the L-shaped insert 51 pushes the deflection hook 77 to deflect, thereby causing the hook body of the deflection hook 77 to disengage from the annular groove 75, thereby releasing the locking pin 5.

[0025] A rotating column 79 is fixedly connected to one end of the hollow connecting column 3. One end of the rotating column 79 passes through the insulation board 2. The hollow connecting column 3 is rotatably connected to the insulation board 2. The outer surface of the hollow connecting column 3 is designed with a frosted material to temporarily limit the rotation of the hollow connecting column 3. A cross groove 81 is opened on the rotating column 79. An inclined groove 82 communicating with the slot 68 is opened inside the hollow connecting column 3. Specifically, when the insulation board 2 needs to be replaced, the rotating column 79 is rotated to drive the hollow connecting column 3 to rotate, so that the inclined groove 82 pushes the slot 69, thereby causing the slot 69 to disengage from the slot 68 and release the insulation board 2.
