Description

Technical Field

[0001] The invention belongs to the technical field of interior decoration, and in particular relates to a connection structure for assembled ceiling keels. Background Art

[0002] The ceiling keel system is equipped with a special lifting system. The light steel keels used for the ceiling include load-bearing keels, covering keels, hangers, pendants, hanging plug-ins, load-bearing keel connectors, covering keel connectors, and hanging rods. The primary and secondary keels are light steel keels, and the aluminum plate is a door-type detachable keel system. Each panel can be easily disassembled and restored. The round tube can be disassembled independently. The hanger is Φ8mm, and the surface of the hanger and bolts is chemically blackened. Its anti-corrosion performance should be higher than the building standard.

[0003] The connection structure of the currently used ceiling keels generally requires that the main keel be connected to the secondary keel through bolts and connectors, and then the secondary keel and the covering keel are connected through connectors, and then the connected keel is connected to the hanger rod as a whole. However, the current connection structure has the following defects: ① When the main keel, the secondary keel and the covering keel are installed, the three are installed vertically through bolts and fasteners. During the installation process, the main keel, the secondary keel, the covering keel and the fasteners need to be positioned, and then installed with bolts, and the bolts are long. ② After being used for a period of time, it may become loose, causing the entire ceiling to be unsafe, and when rust occurs, it is not convenient to disassemble. ② After the entire keel frame body is installed, the keel frame body needs to be connected to the hanger, and the hanger and the keel are connected through the keel hanger, and during installation, the keel hanger needs to be twisted. When the hanger is located in the middle of the entire keel frame body, it is not easy for people to operate and twist it. In addition, multiple hangers are required when the keel frame body is installed. If the amount of twisting of the keel hangers corresponding to the hangers is different, this will cause the entire keel to be installed not flat enough. Summary of the invention

The top of the second hinge rod 505 extends to the inside of the connecting groove 503 and is movably connected to the side of the friction top rod 502. The bottom of the suspension rod 11 is fixedly connected to a connecting head 12. The cross-section of the front of the connecting head 12 is trapezoidal. The side of the connecting head 12 is provided with a card slot 13 that matches the elastic card piece 507. The first hinge rod 506 and the second hinge rod 505 are connected to the front of the inner cavity of the inner wall of the sliding buckle joint 5 through a torsion spring.

[0032] Working principle:

[0033] The cladding keel 1 is placed on the table, the movable holder 2 is slidably installed on the inner side of the cladding keel 1, and then the secondary keel 4 is buckled on the movable holder 2. At this time, the push rod 201 is pushed to make the rubber card ball 202 enter the open groove 402, so that the cladding keel 1 is connected with the secondary keel 4. Since the rubber card ball 202 enters the inside of the open groove 402, it pushes the first rack 401 to move, thereby driving the gear 403 to rotate, and then the gear 403 drives the second rack 404 to move, so that the card node at one end of the second rack 404 extends to the side of the secondary keel 4 and is snapped with the inner side wall of the cladding keel 1, so as to ensure that the movable holder 2 will not slide, and then the main keel 3 is pressed and buckled on the top of the secondary keel 4, so that the buckle joint 10 is driven by the spring 8 to enter the inside of the buckle groove 9, so that the main keel 3 and the secondary keel 4 are installed. At this time, the sliding buckle joint 5 is installed in the sliding groove 6. After that, the first hinge rod 506 is rotated counterclockwise, and the first hinge rod 506 pushes the second hinge rod 505 to rotate clockwise, so that the telescopic rod 504 pushes the friction top rod 502 to move toward the side wall of the sliding groove 6, so that the sliding buckle joint 5 is fixed at the fixed position of the sliding groove 6 to prevent the entire keel frame from sliding. After the installation of the two adjacent keel frame bodies is completed, the two adjacent keel frame bodies can be connected by adjusting the stretch rod 15, and finally the ceiling can be installed at the bottom of the covering keel 1.
