Description

a rocking chair

[technical field]

The invention relates to a rocking chair.

[Background technique]

Existing rocking chairs generally include a support frame and a seat frame that is arranged on the support frame and can swing back and forth relative to it. However, the driving structure for driving the swing of the seat frame relative to the support frame is relatively complicated. The publication number is CN201585742U, and the name is a utility model patent for a baby rocking chair. The driving structure is relatively simple, and it includes a rocking chair support frame and a seat frame. The front part is rotatably connected with the drive rod through the third rotating shaft, and the other end of the drive rod is eccentrically rotatably connected with the turntable. The rocking chair with this structure has the following disadvantages: 1. The first rotating shaft is the center of rotation of the entire seat frame during the swing process, and the third rotating shaft is the driving point that makes the seat frame swing, that is, the driving point and the turning point of the seat frame These are two different points, so that when the rocking chair is used for a long time, if the first rotating shaft as the turning point fails, the turntable will still drive the driving rod to swing, and the driving rod will drive the seat frame through the third rotating shaft. Swing, like this, when the first rotating shaft fails, the seat frame is still driven to swing, which is easy to cause the baby in the seat frame to fall to the ground, and the rocking chair has a safety hazard. 2. The front end of the seat frame is connected to the driving rod through the third rotating shaft, and the driving rod is movably connected to the turntable. In this way, the driving mechanism for driving the swing of the seat frame is arranged between the front end of the seat frame and the rocking chair support, and the driving mechanism is just arranged on the Below the legs of the user, infants and young children are easy to accidentally touch the driving mechanism, which has potential safety hazards. 3. Since the driving mechanism is arranged between the front end of the seat frame and the rocking chair support frame, the whole rocking chair frame cannot be combined with the dining chair and the trolley. 4. Since the driving mechanism is arranged between the front end of the seat frame and the rocking chair brace, the assembly and disassembly process of the whole rocking chair is not convenient enough.

The front end of the seat in the prior art is connected with the rocking chair support frame, and the seat A drive mechanism is arranged between the rocking chair braces, so it is difficult to adjust the angle of the seat.

5. The front and rear ends of the seat frame are not connected with the support frame, and the driving mechanism is completely packaged with the installation shell, which is convenient to fold, small in size and beautiful in appearance.

6. A deceleration mechanism can be used between the seat frame and the driving mechanism, which can reduce the sense of drop when the driving mechanism has a height difference between the upper and lower heights, and the swing is softer and smoother.

7. The rotating shaft described in the present invention is not only the rotation point where the seat frame swings relative to the support frame, but also the driving point that drives the seat frame to rotate relative to the support frame, so that the rotation point of the seat frame is overlapped with the driving point, and the rotation point and No interference will occur between drive points.

8. The front and rear ends of the seat frame are not connected with the support frame, and the driving mechanism is completely packaged with the installation shell, so that children who touch the product will not have safety accidents.
