Problems solved by technology

The rocking chair with this structure has the following disadvantages: 1. The first rotation axis is the rotation of the entire seat frame during the swing process, and the third rotation axis is the driving point for the seat frame to swing, that is, the driving point and the rotation 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. In this way, 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 hazar

Description

[technical field] [0001] The invention relates to a rocking chair. [Background technique] [0002] Existing rocking chairs generally comprise a support frame and a seat frame that is arranged on the support frame and can swing back and forth relative thereto. 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 an invention patent of a baby rocking chair. The driving structure is relatively simple, and it includes a rocking chair support frame and a seat frame. The third rotating shaft is rotationally connected with the driving rod, and the other end of the driving rod is eccentrically rotationally connected with the turntable. The rocking chair with this structure has the following disadvantages: 1. The first rotation axis is the rotation of the entire seat frame during the swing process, and the third rotation axis is the driving point for th...
