Detailed Description

The sofa base with rocking and rotating functions of the present invention will be further described with reference to fig. 1 to 3.

A sofa base with swinging and rotating functions is characterized in that: comprising a swinging mechanism and a rotating mechanism 1. The rotating mechanism comprises a bottom frame 13, a fixed disc 12 fixed on the bottom frame 13 and a rotating disc 11 rotatably arranged on the fixed disc 12. The chassis 13 is composed of a ring and a cross welded in the ring. The fixed plate 12 is fixed to the center of the cross of the base frame 13 by bolts. The swing mechanism comprises two sets of symmetrically arranged swing assemblies 2, each set of swing assembly 2 comprises an installation plate 21 installed on the rotating disc 11, the upper end of each set of swing assembly 2 is pivoted to the installation plate 21 through a pin rod, the lower end of each set of swing assembly 2 can swing freely through two swing rods 22 and can be connected to the lower ends of the two swing rods 22 simultaneously to supply a connecting plate 23 for installing the functional iron frame 3, and the two swing rods 22 in each set of swing assembly 2 are connected to the corresponding installation plate 21 in a front-back distribution state.

Specifically, the fixed disk 12 is provided with an annular and downward concave lower groove 121, the rotating disk 11 is provided with an annular and upward concave upper groove 111, the upper groove 111 and the lower groove 121 correspond to each other up and down to form a ball groove, and balls are arranged in the ball grooves, so that the rotating disk 11 is rotatably connected to the fixed disk 12.

Two parallel mounting tubes 14 for mounting the swing assembly 2 are bolted to the upper surface of the rotary plate 11. Namely, the mounting plates 21 of the two swing assemblies 2 are respectively positioned at the two ends of the mounting pipe 14. The distance between the two sets of rocking assemblies 2 can be conveniently increased by mounting the tube 14, i.e. the distance between the two sets of rocking assemblies 2 need not be limited by the size of the rotary disc 11.

The mounting panel 21 includes vertical and supplies the plate body portion and the horizontally connecting portion of rocking rod 22 pin joint, the connecting hole has been seted up on the connecting portion, has also seted up the connecting hole on the installation pipe 14, connecting hole on the connecting portion corresponds and can realize the fixing of mounting panel 21 on installation pipe 14 after penetrating the bolt with the connecting hole on the installation pipe 14. In this embodiment, the plurality of connection holes on the mounting tube 14 extend along the length direction of the mounting tube 14, and when the connection holes on the mounting plate 21 are butted against different connection holes on the mounting tube 14, the distance between the two sets of swing assemblies 2 can be adjusted.

A limit plate 221 for limiting the swing angle of the swing lever 22 is formed on the side surface of the swing lever 22. Namely, the limiting plates 221 are formed on the opposite side surfaces of the two swing rods 22 in the same swing assembly 2, the limiting plate 221 on the swing rod 22 on the rear side can abut against the rear end portion of the mounting plate 21 when swinging forward to limit the lower end of the swing rod 22 from continuously swinging forward, and the limiting plate 221 on the swing rod 22 on the front side can abut against the front end portion of the mounting plate 21 when swinging backward to limit the lower end of the swing rod 22 from continuously swinging backward, so that the swing safety of the present invention is improved.

The connecting plate 23 is an L-shaped structure including a vertical plate pivotally connected to a lower end of the rocking bar 22 by a pin and a horizontal plate having a mounting hole 231 and to which the functional iron frame is mounted.

When the sofa is used, the functional iron frame 3 of the sofa is directly arranged on the connecting plate 23, so that the functional iron frame, namely the sofa, has the functions of swinging and rotating, and the comfort of the sofa is obviously improved; meanwhile, the invention can be matched with functional iron frames of all sofas for use.
