[0002] The keel is the skeleton and base material of decoration and is very commonly used. In the prior art, the keels used for suspended ceilings are mostly light steel keels. During the installation operation, the main keel needs to be fixed first, and then the secondary keel is installed at a reasonable interval on the lower side of the main keel. However, since multiple secondary keels need to be installed, in the actual operation process, the installer needs to first measure the length of the main keel, and mark the position where the secondary keel is installed on the main keel, and finally use this to position and install the secondary keel horizontally on the lower side of the main keel. During the installation process, since the height of the suspended ceiling is usually higher than a person's height, it is necessary to climb up with the help of a ladder. At the same time, it is necessary to frequently take the prefabricated secondary keel from the lower side of the ladder, and then manually lift it to the lower side of the main keel for installation. This process is not only troublesome, but also laborious, and a single person needs to frequently climb up and down the ladder. Summary of the Invention

[0017] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-11 , the present invention provides an embodiment: a multifunctional fine decoration keel combination structure and its installation method, including a first support frame plate 1, a second support frame plate 2 and a connecting component, the upper ends of the first support frame plate 1 and the second support frame plate 2 are symmetrically fixed with a top frame 3, the inner walls of the two groups of top frames 3 are symmetrically rotatably installed with two groups of first rollers 4 and second rollers 5, a connecting plate 11 is provided between the first support frame plate 1 and the second support frame plate 2 through an adjusting component, a second screw 15 is rotatably installed on the rear side of the first support frame plate 1, a second screw sleeve 16 is fixedly installed on the second support frame plate 2, and the second screw sleeve 16 is threadedly sleeved on the first On the two screw rods 15, the rear ends of the first support frame plate 1 and the second support frame plate 2 are symmetrically provided with a limiting assembly, and the lower sides of the first support frame plate 1 and the second support frame plate 2 are fixedly provided with a hanging rod 21, and the end of the hanging rod 21 is rotatably installed with a limiting rod 22. The connecting assembly includes a sleeve rod 24 and an insertion rod 25, and the insertion rod 25 is movably inserted into one end of the sleeve rod 24. The ends of the sleeve rod 24 and the insertion rod 25 away from each other are respectively provided with an insertion block 27 and a sleeve block 26, and a locking assembly is provided between the sleeve block 26 and the insertion block 27. The outer wall of the first support frame plate 1 is fixedly provided with an insertion block 27, and the outer wall of the second support frame plate 2 is fixedly provided with a sleeve block 26.

[0019] First, adjust the width of the two sets of top frames 3 by rotating the second screw 15 and clamp them on the main keel, so that the first roller 4 and the second roller 5 are respectively attached to the upper side and the left and right outer walls of the main keel, and then change the height of the connecting plate 11 by adjusting the assembly to match the height of the secondary keel, and finally complete the splicing of the connecting assembly.

[0020] The first support frame plate 1, the second support frame plate 2 and the top frame 3 are all made of steel to ensure that they have sufficient strength to avoid deformation and can bear the weight of the secondary keel.

[0021] As a preferred implementation in this embodiment, Figure 4 、 Figure 6 and Figure 9 As shown, the surface rubber layers of the first roller 4 and the second roller 5 are both provided with strip-shaped anti-slip grooves, the first roller 4 is arranged longitudinally, the second roller 5 is arranged transversely, the first roller 4 and the second roller 5 are arranged at right angles, the first roller 4 is located on the upper inner wall of the top frame 3, and the second roller 5 is located on the lower side of the first roller 4.

[0022] In this structure, the surfaces of the first and second rollers 4, 5, are bonded with wear-resistant rubber pads no less than two millimeters thick. The striped, anti-slip design allows them to rotate on the keel through friction, achieving a displacement effect. The right-angled design of the first and second rollers 4, 5 allows the first rollers 4 on both sets of top frames 3 to rest on the upper side of the keel, while the second rollers 5 on both sets of top frames 3 can contact the outer walls of the keel on both sides, ensuring smooth rotation while providing a position-limiting effect.

[0023] As a preferred implementation in this embodiment, Figure 4 、 Figure 6 and Figure 8 As shown, the adjustment assembly includes a support plate 6, and support plates 6 are symmetrically arranged on the upper and lower sides of the first support frame plate 1 near one end of the second support frame plate 2. A first screw 9 is rotatably installed between the two groups of support plates 6 through bearings, and a first screw sleeve 10 is provided on the first screw 9 through a threaded sleeve, and the first screw sleeve 10 is fixedly installed in the receiving plate 11.

[0024] This structure allows the height of the splicing plate 11 to be adjusted according to the size of the secondary keel to be installed during use and the requirements during installation, which can increase the applicability and use effect of the splicing plate 11.

[0025] The receiving plate 11 is made of steel and has vertical reinforcing ribs at the bottom. Figure 5 and Figure 7 As shown, this structure can increase the strength and deformation resistance of the connecting plate 11, thereby making it less likely to deform and effectively supporting the secondary keel.

[0026] As a preferred implementation in this embodiment, Figure 3 、 Figure 5 and Figure 8 As shown, clamping strips 8 are symmetrically provided on the upper and lower sides of one end of the first support frame plate 1 close to the second support frame plate 2 , and guide grooves 7 adapted to the clamping strips 8 are opened on the side of the support plate 6 .

[0027] In this structure, an opening that is compatible with the guide groove 7 is provided on the surface of the first support frame plate 1. When the clip 8 is inserted into the guide groove 7 and contracts with the support plate 6, the clip 8 can pass through the opening on the side of the first support frame plate 1, thereby ensuring that the clip 8 and the support plate 6 can perform parallel telescopic movements, so that the distance between the first support frame plate 1 and the second support frame plate 2 can be adjusted. At the same time, the support plate 6 and the clip 8 can support each other and ensure that the adjustment component can be effectively operated.

[0028] As a preferred implementation in this embodiment, Figure 4 、 Figure 5 and Figure 7 As shown, two groups of guide plates 12 are symmetrically arranged at both ends of the material receiving plate 11, and guide rails 13 are longitudinally opened on the first support frame plate 1 and the second support frame plate 2. The rear guide plate 12 is inserted in the guide rail 13 and slides up and down, and a mounting hole 14 is opened on the surface of the material receiving plate 11.

[0029] In this structure, the spacing between the front and rear guide plates 12 matches the spacing between the guide rails 13 and the front edges of the first support frame plate 1 or the second support frame plate 2. This prevents the splicing plate 11 from flipping or tilting during use due to the fibers of the guide plates 12, while allowing for horizontal movement due to the guidance of the guide rails 13. Furthermore, the mounting holes 14 facilitate the installation of the secondary purlin, allowing screws and other mounting hardware to be inserted through the mounting holes 14 to connect the secondary purlin to the primary purlin.

[0030] As a preferred implementation in this embodiment, Figure 3 、 Figure 6 and Figure 9 As shown, the limiting assembly includes a third screw sleeve 17, and the rear ends of the first support frame plate 1 and the second support frame plate 2 are both installed with a third screw sleeve 17, and a third screw rod 18 is threadedly installed in the third screw sleeve 17, and a splint 19 is rotatably installed on the inner end of the third screw rod 18, and an anti-slip rubber pad 20 is glued to the outer wall of the splint 19.

[0031] The surface of the anti-slip rubber pad 20 in this structure is provided with anti-slip grooves with longitudinal stripes. This structure is used to rotate the third screw 18 so that the splint 19 cooperates with the anti-slip rubber pad 20 to fit the outer wall of the keel, thereby increasing the friction through extrusion contact, so that the device will not be displaced on the keel at will, so that it is convenient to operate when the position of the secondary keel needs to be fixed.

[0032] As a preferred implementation in this embodiment, Figure 3 、 Figure 4 and Figure 6 As shown, the cross section of the hanging rod 21 is L-shaped, and a magnetic block 23 that adapts to each other is fixedly provided on the side opposite to the end of the limiting rod 22.

[0033] In this structure, the hanging rod 21 and the magnetic block 23 are both made of steel, and the side walls are provided with reinforcing ribs. The reinforcing ribs increase its strength and deformation resistance, so that this part is not easy to deform and can well bear the secondary keel. At the same time, the magnetic forces of the two groups of magnetic blocks 23 are positive and negative poles respectively. Through the principle of attraction between different shapes, the magnetic block 23 can connect the two limit rods 22 by magnetic attraction when the limit rod 22 is erected, so that the limit rod 22 will not naturally rotate and fall due to gravity, so that the limit rod 22 can stand on the side of the hanging rod 21, limit the secondary keel carried by the hanging rod 21, and prevent it from sliding off the hanging rod 21.

[0034] As a preferred implementation in this embodiment, Figure 8 、 Figure 10 and Figure 11 As shown, the locking assembly includes a movable groove 28, a movable groove 28 is opened at the upper end of the insert block 27, a spring 29 is longitudinally arranged in the movable groove 28, a clamping block 30 is movably installed at the opening of the insert block 27, and the lower end of the clamping block 30 is abutted against the end of the spring 29, a clamping groove 31 is horizontally opened on the sleeve block 26, the inner diameter of the clamping groove 31 is adapted to the outer diameter of the clamping block 30, and the upper end of the clamping block 30 is hemispherical.

[0035] This structure is used to connect multiple sets of rods 24 and insert rods 25, and can also connect the first support frame plate 1 and the second support frame plate 2, so that the device can be horizontally connected for use, such as Figure 1 and Figure 2 As shown, the secondary keel can be connected by multiple groups of splicing to ensure that the secondary keel can be placed horizontally on the lower side of the main keel using this device, thereby facilitating the displacement and subsequent installation of the secondary keel. The hemispherical clamping block 30 at the upper end can facilitate its entry into the clamping slot 31 or its removal. By pressing the clamping block 30, when the insert block 27 is inserted into the sleeve block 26, the sleeve block 26 squeezes its end, allowing it to be retracted into the movable groove 28, thereby facilitating the insertion of the insert block 27 into the sleeve block 26. After being inserted into the clamping slot 31, the clamping block 30 can also be pressed to facilitate its removal from the sleeve block 26.

[0036] Working principle: Adjust the position of the receiving plate 11 according to the height of the secondary keel in advance. Just rotate the first screw 9 so that the first screw sleeve 10 drives the receiving plate 11 to rise and fall through the thread action of the first screw 9. The synchronous guide plate 12 will slide longitudinally along the guide rail 13. The height of the receiving plate 11 only needs to ensure that the secondary keel can be placed between the receiving plate 11 and the top frame 3 and can be naturally removed. In addition, it can be adjusted as much as possible until the secondary keel is close to the lower side of the main keel when the device is installed on the main keel. Figure 1 and Figure 2 .

[0037] During installation, first install a set of devices on the middle main keel. The specific operation is as follows: rotate the second screw 15 so that it is threadedly matched with the second screw sleeve 16, so that the first support frame plate 1 and the second support frame plate 2 move away from each other, causing the two groups of top frames 3 to open, and then the two groups of top frames 3 are clamped on the main keel from the bottom, so that the first roller 4 is on the upper side of the main keel, and finally rotate the second screw 15 so that the second screw sleeve 16 drives the second support frame plate 2 and the first support frame plate 1 to move closer through the thread action, so that the two groups of top frames 3 are close to each other, causing the second rollers 5 on the two groups of top frames 3 to fit respectively on both sides of the secondary keel, as shown in FIG. Figure 6 In the state shown, in this way, multiple groups of main keels are installed in sequence, and at least three groups are set at relatively equidistant intervals. Then, multiple groups of sleeve rods 24 are connected, and through the extension and contraction of the sleeve rods 24 and the insertion rods 25, their combined length can be connected to the first support frame plate 1 and the second support frame plate 2 on different groups. The specific operation of the connection is to put the second screw sleeve 16 on the insertion block 27, and press the block 30 downward so that the block 30 is received into the opening of the movable groove 28 and compress the spring 29, and then insert the block 27 into the sleeve block 26. After the block 30 is aligned with the slot 31, the spring 29 in the compressed state can push the block 30 out by the restoring force, and insert it into the slot 31 to lock the connection between the sleeve block 26 and the insertion block 27. In this way, Figure 1 and Figure 2 As shown, multiple groups of first support frame plates 1 and second support frame plates 2 are connected in series.

[0038] Finally, multiple groups of secondary keels are placed on multiple groups of hanging rods 21, and the limiting rods 22 are rotated so that the magnetic blocks 23 on the mutually cooperating limiting rods 22 are magnetically connected, so that the secondary keels cannot slip off. Alternatively, the limiting rods 22 can be first fixed by the magnetic connection of the magnetic blocks 23, and then the secondary keels are placed from the upper openings of the limiting rods 22 and the hanging rods 21. During the installation operation, a group of secondary keels are placed horizontally on several groups of receiving plates 11, and then the device is pushed so that the first roller 4 and the second roller 5 are pressed against the main keel to drive the device to slide, so that several groups of devices and multiple groups of secondary keels can be moved horizontally. When the device is moved horizontally to the installation position, the third screw 18 can be rotated first so that the third screw 18 drives the splint 19 close to the outer wall of the main keel through the threaded connection with the third screw sleeve 17, and contacts and squeezes the outer wall through the anti-slip rubber pad 20 to increase the friction force and achieve the effect of limiting. When one set of secondary keels is installed, the third screw 18 is rotated to loosen the clamping plate 19, and then the device is slid and the other set of secondary keels is removed from the hanging rod 21 and placed on the receiving plate 11. When the device is used, the secondary keels are installed from one end of the main keel to the other end, and the side where the second screw 15 is located must be facing the direction of installation, that is, the receiving plate 11 is in the starting direction.
