The inner walls of the U-shaped slot are respectively provided with multiple segments of serrated protrusions on both sides, and the multiple segments of protrusions are respectively matched with the two sides of the arrow-shaped plug.

[0007] Preferably, the insertion end of the U-shaped slot has a flared opening.

[0008] Preferably, the connector is hinged to the mounting plate via a hinge shaft.

[0009] Preferably, the insertion end of the U-shaped lock has a flared opening.

[0010] Preferably, a limit block is provided on the lock body in the counterclockwise rotation direction of the bolt.

[0011] Preferably, the buckle includes a connecting piece and a U-shaped locking hook, with the U-shaped locking hook fixedly connected to the connecting piece.

[0012] Preferably, the connecting piece is provided with multiple mounting holes, and the connecting piece is fixedly installed on the backrest or side of the sofa by screws.

[0013] Preferably, the locking mechanism is fixedly installed on the upper part of the back and left and right sides of the sofa seat, and the unlocking pull cord is exposed on the upper surface of the sofa seat.

[0014] Preferably, the mounting plate is fixedly connected to the bottom connection side of the sofa seat, sofa backrest, or sofa siderest by screws.

[0015] The beneficial effects of this utility model are: (1) The first hardware connector includes a lock and a buckle. The lock can be unlocked by pulling the unlocking rope. When locked, only the lock and buckle need to be pressed together to lock. When the second hardware connector is locked, it is inserted by the plug end and the slot end. When opened, it is opened and closed by staggered opening and closing, which is convenient for disassembly and assembly; (2) The inner walls of the U-shaped slot of the second hardware connector are respectively provided with serrated multi-segment insertion ports on both sides. The multi-segment insertion ports are respectively matched with the two sides of the arrow-shaped plug, which can realize multi-segment locking, realize gapless connection, and achieve compact and tight splicing without leaving gaps.

Detailed Implementation

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example: A modular sofa that is easy to assemble and disassemble includes several sofa seats 1, several sofa backrests 2 corresponding to the sofa seats, and sofa siderests 3 on both sides. The upper part of the sofa seats and sofa backrests are connected by a hardware connector 4, and the lower part is connected by two hardware connectors 5. The hardware connector 1 includes a lock 6 and a buckle 7. The lock includes a lock body 8 and a lock tongue 11. The lock body has a U-shaped lock opening 9. The lock tongue is hinged to the lock body by a pin 10 and is reset by a torsion spring 12 to ensure that the lock tongue remains in the locked position after reset. The buckle is inserted into the U-shaped lock opening and locked by the lock tongue. The lock tongue is equipped with an unlocking pull rope 13. The hardware connectors 2 include a mounting plate 17 and a plug 18. The mounting plate is equipped with a plug 20 at the front end and a slot 21 at the rear end. The plug end and the slot end are designed to be inserted into each other.

[0018] The plug end is an arrow-shaped plug, and the slot end is a U-shaped slot. The inner wall of the U-shaped slot has multiple segments of serrated prongs on both sides, which mate with the two sides of the arrow-shaped plug. The insertion end of the U-shaped slot has a flared opening.

[0019] The connector and mounting plate are hinged together via hinge shaft 19. The insertion end of the U-shaped lock mouth has a flared opening. A limit block 14 is provided on the lock body in the counterclockwise rotation direction of the bolt.

[0020] The buckle includes a connecting piece 15 and a U-shaped locking hook 16, with the U-shaped locking hook fixedly connected to the connecting piece. The connecting piece has multiple mounting holes, and is fixedly installed on the sofa back or side panel using screws.
