[0020] The sofa with the above structure and quick-assembly structure is installed by inserting the armrest 4 on the plug-in board 3, and locking the armrest 4 on the plug-in board 3 by the locking mechanism 100. Then the user inserts the backrest 6 on the backrest board 5 to complete the installation. In daily use, the user can pop out the backrest 6 toward the seat cushion by the pop-up mechanism 200, so that the user can lean back in multiple ways. Compared with the prior art, the overall installation and assembly speed of the sofa is improved, and a variety of backrest methods can be provided to the user.

[0021] like Figure 3 As shown, in some embodiments of the utility model, the armrest part (4) includes a guide rail (41) fixed on each plug-in board (3), a sofa armrest (42) is provided on one side of each plug-in board (3), a connecting plate (43) is fixed on each sofa armrest (42), and a plug-in slot (44) is provided on each connecting plate (43), and each plug-in slot (44) is movably plugged into an adjacent guide rail (41). During installation, the user installs the sofa armrest 42 on the connecting plate (43) by bolts, and at this time, the user plugs the plug-in board 3 into the adjacent guide rail (41), so that the connecting plate (43) is plugged into the plug-in board (3).

[0022] like Figure 3As shown, in some embodiments of the utility model, the backrest (6) includes slide rails (61) symmetrically fixed on the backrest (5), and a hinged plate (62) is movably inserted on each of the slide rails (61), and a sofa backrest (63) is movably hinged above each of the hinged plates (62). During installation, the user hinges the sofa backrest 63 on the hinged plate (62), and then the user movably inserts the hinged plate (62) on the backrest (5) through the slide rails (61).

[0023] like Figure 3 and 4 As shown, in some embodiments of the utility model, in order to achieve the effect of locking the armrest part (4) on the plug-in board (3), the locking mechanism (100) includes hinge grooves (101) arranged on the front and rear sides of each of the connecting plates (43), a movable locking rod (102) in each of the hinge grooves (101), a baffle (103) fixed on each of the hinge grooves (101), a snap-fit ​​head (104) fixed under each of the locking rods (102), snap-fit ​​grooves (105) symmetrically fixed on the left and right sides of the base frame (1), the snap-fit ​​head (104) snaps into the adjacent snap-fit ​​grooves (105), and a plurality of first springs (106) are fixedly connected between each of the locking rods (102) and the adjacent hinge grooves (101).
