DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-5 This application is described in further detail.

[0020] The present application embodiment discloses a locking member for gathering a sofa, referring to Figure 1 , comprising two pads 1 and an adjusting assembly, wherein a vertical plate 2 is fixedly connected to the surface of the pad 1, wherein a convex plate 3 is fixedly connected to the top of one pad 1, a screw rod 4 is fixedly connected to the side of the convex plate 3 close to the other pad 1, and a locking block 5 is threadedly connected to the outer side of the screw rod 4, and the two vertical plates 2 are respectively placed on the inner side walls of the two sofas that need to be gathered and fit tightly with the inner side walls of the sofas, and by rotating the locking block 5, the locking block 5 can move toward the vertical plate 2 outside the screw rod 4 until the locking block 5 is tightly fitted with the vertical plate 2 away from the convex plate 3, thereby locking the position of the two sofas that need to be gathered.

[0021] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The adjusting component includes a rectangular groove 6 opened on the side opposite to each other of the two pads 1, an extension plate 7 is arranged inside the rectangular groove 6, a fixing groove 8 is opened at the bottom of the extension plate 7, a rubber pad 9 is bonded inside the fixing groove 8, a triangular positioning block 10 is installed at the bottom of the rubber pad 9, and a plurality of triangular positioning grooves 11 for the triangular positioning blocks 10 to be embedded are opened at equal intervals at the bottom of the rectangular groove 6. The triangular positioning block 10 is initially located inside one of the triangular positioning grooves 11. When the extension plate 7 is slid, the triangular positioning block 10 is squeezed, and the rubber pad 9 is compressed. As the extension plate 7 slides, the triangular positioning block 10 enters the inside of the other triangular positioning grooves 11, and the position of the extension plate 7 is fixed, which increases the stability of the extension plate 7 inside the rectangular groove 6. By placing a sofa cushion on the surface of the pad 1 and the extension plate 7, the area of ​​the required pad 1 can be adjusted according to the size of the sofa by sliding the extension plate 7.
