Referring to fig. 3 and 4, the end of the armrest connecting piece 1 far away from the fixing piece 2 is also connected with a rotating piece 3, the rotating piece 3 is connected with the armrest connecting piece 1 through a second fixing piece 12, a waist-shaped hole 13 is also formed in the second fixing piece 12, the other end of the armrest connecting piece 1 is connected to the waist-shaped hole 13 of the second fixing piece 12 through a riveting piece 14, the rotating piece 3 comprises a rotating rod 31 and at least one rotating unit 32, the upper part of the rotating rod 31 is fixedly connected with the second fixing piece 12, the rotating unit 32 at the uppermost part and the rotating rod 31 form a rotating pair, the rotating unit 32 and the adjacent rotating units 32 are also connected in a rotating pair mode, an angle iron 17 is fixed on the rotating unit 32 at the bottommost part, and the angle iron 17 is fixedly connected to the support 4 of the sofa body through bolts.

By pushing the armrest connecting member 1, the rotating rod 31 and the rotating unit 32 and the adjacent rotating units 32 can rotate with each other, so that one end of the armrest connecting member 1 connected with the rotating member 3 is folded relative to the sofa body.

In this embodiment, the first fixing piece 11 and the second fixing piece 12 are the same and are both sheet structures made of manganese steel materials.

The rivet 14 in this embodiment is a rivet, and the rivet can move in the waist-shaped hole 13, so that one end of the handrail connecting piece 1 can be folded conveniently. The armrest connection 1 has a near surface 18 (fig. 1) and a far surface 19, the near surface 18 being a surface near the sofa body, the far surface 19 being a surface far from the sofa body, the sofa body not being illustrated in this embodiment. The approaching surface 18 of the armrest connecting piece 1 is contacted with the second fixing piece 12 and is connected by the riveting piece 14, and the far surface 19 of the armrest connecting piece 1 is contacted with the first fixing piece 11 and is connected by the riveting piece 14, so that the two ends of the armrest connecting piece 1 are respectively connected with the first fixing piece 11 and the second fixing piece 12 in a staggered way.

A gasket 15 (as shown in fig. 1) is arranged between the riveting piece 14 and the first fixing piece 11 and the second fixing piece 12, and the gasket 15 is made of plastic material.

An elastic member 16 (as shown in fig. 1) is connected between the rotating member 3 and the fixing member 2, and in this embodiment, the elastic member 16 is an elastic band, and other embodiments may also be a serpentine spring.

In order to improve stability, a triangular plate is connected between the fixing member 2 and the angle steel, and a sponge is filled between the upper part of the triangular plate and the elastic member 16.

Referring to fig. 5 and 6, the rotation lever 31 has a first limit tooth 311, a first limit surface 312, and a first reset surface 313; if the rotation unit 32 is one, the rotation unit 32 has a second limiting surface 322, a second limiting tooth 321, and a second reset surface 323. The first limiting teeth 311 of the rotating lever 31 are engaged with the second limiting teeth 321 of the nearest rotating unit 32. When the sofa armrest is in a normal state (non-folded state), the first reset surface 313 and the second reset surface 323 are abutted against each other. When one corner of the sofa armrest needs to be folded, the rotating rod 31 or the armrest connecting piece 1 is pushed, and the rotating rod 31 rotates relative to the rotating unit 32, so that folding is realized. The included angle between the first limiting surface 312 and the second limiting surface 322 is an angle at which the sofa armrest can be folded. When the first limiting surface 312 abuts against the second limiting surface 322, the sofa armrest is at the maximum folding position.

If the rotation units 32 are two or more, the rotation units 32 further have a third limiting surface 325, a third limiting tooth 324, and a third reset surface 326, the third reset surface 326 of the rotation unit 32 can be abutted against the third reset surface 326 of the adjacent rotation unit 32, the third limiting tooth 324 can be engaged with the third limiting tooth 324 of the adjacent rotation unit 32, and the third limiting surface 325 can be abutted against the third limiting surface 325 of the adjacent rotation unit 32. And a third spacing tooth 324 engaged with an adjacent rotating unit 32.

By adding the rotating units 32, the turning angle and turning times of the sofa armrest can be increased, and at this time, the sofa armrest can be at the maximum turning position only when the third limiting surfaces 325 of all the rotating units 32 are abutted with the limiting surfaces of the adjacent rotating units 32 and the first limiting surfaces 312 of the rotating rods 31 are abutted with the second limiting surfaces 322 of the nearest rotating units 32. Similarly, the sofa armrest is in a normal state (non-folded state) only when the first reset surface 313 of the rotating lever 31 abuts against the second reset surface 323 of the nearest rotating unit 32 and the third reset surfaces 326 of all rotating units 32 abut against the third reset surfaces 326 of the adjacent rotating units 32.

The rotational friction force between the rotational lever 31 and the rotational unit 32 and between the rotational unit 32 and the adjacent rotational unit 32 is increased by adjusting the tightening degree of the rotational pin 33 by rotationally connecting the rotational lever 31 and the rotational unit 32 and between the rotational unit 32 and the adjacent rotational unit 32 via the rotational pin 33, and the rotational friction force can stabilize each other between the rotational lever 31 and the rotational unit 32 within a certain range. When the user pushes the armrest connecting unit 1, the rotating rod 31 or the rotating unit 32 by an external force, the external force is larger than the sliding friction force, so that one corner of the armrest connecting unit 1 can be folded, and the force of the user leaning the hand on the sofa armrest is not enough to fold the single corner of the armrest connecting unit 1.
