Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, the utility model discloses a sofa of easily getting up, including internal frame structure, internal frame structure includes back frame 1, cushion frame construction and base frame 2, and cushion frame construction and back frame 1 set up in base frame 2 top, and back frame 1 is located the rear end of cushion frame construction, the cushion frame includes preceding cushion frame 3 and back cushion frame 4.

The front cushion frame 3 and the rear cushion frame 4 are both rectangular in shape. The base frame 2 includes a rectangular bottom frame structure provided at the bottom, and a front frame structure vertically provided at the front end of the bottom frame structure. The bottom frame structure is rectangular in shape. The front frame structure is in a door-shaped structure.

The bottom of the front cushion frame 3 is rotatably connected with the front frame structure of the base frame 2. The front cushion frame 3 has a stopper 303 at the bottom of the front end. The limiting rod 303 limits the forward rotation angle of the front cushion frame 3, and when the limiting rod 303 abuts against the front frame structure, the included angle between the front cushion frame 3 and the horizontal plane is 45-60 degrees.

The rear end of the front cushion frame 3 is rotationally connected with the front end of the rear cushion frame 4, and two sides of the rear cushion frame 4 are provided with handrail frames 5; be equipped with connecting rod 6 mechanism between 4 both sides of back cushion frame and the base frame 2, connecting rod 6 mechanism includes connecting rod 6 and elevation structure, elevation structure locates

base frame

2, 6 one end of connecting rod is rotated and is connected back cushion frame 4, and the other end is rotated and is connected elevation structure, be equipped with the elastic limiting part of restriction elevation structure elevating height between elevation structure and the base frame 2, base frame 2 is equipped with the advancing mechanism who is used for 4 heights of cushion frame after the lifting.

The lifting structure is set to be a telescopic rod 7, the base frame 2 is vertically provided with a telescopic rod 7 on two sides of the rear cushion frame 4 respectively, one end of the connecting rod 6 is connected with the rear cushion frame 4 in a rotating mode, and the other end of the connecting rod is connected with the top end of the telescopic rod 7 in a rotating mode.

The elastic limiting part is a spring 8, the upper end of the spring 8 is connected with the top end of the telescopic rod 7, and the lower end of the spring 8 is connected with the bottom of the base frame 2.

A horizontal first rotating shaft 302 is arranged at the front end of the base frame 2, the bottom of the front cushion frame 3 is rotatably connected with the first rotating shaft 302, and an L-shaped first connecting frame 301 extending backwards is arranged at the rear end of the front cushion frame 3; the front end of the rear cushion frame 4 is provided with an L-shaped second connecting frame 401 extending forwards, the tail ends of the first connecting frame 301 and the second connecting frame 401 are rotatably connected through a second rotating shaft 304 arranged horizontally, the height of the first rotating shaft 302 is higher than that of one end of the connecting rod 6 rotatably connected with the telescopic rod 7 when the telescopic rod 7 is positioned at the lowest height, and the distance between the first rotating shaft 302 and the second rotating shaft 304 is equal to the length of the connecting rod 6.

The base frame 2 is provided with a plurality of support frames 201 for supporting the rear cushion frame 4, and when the bottom of the rear cushion frame 4 abuts against all the support frames 201, the front cushion frame 3 and the rear cushion frame 4 are located at the same horizontal height.
