DETAILED DESCRIPTION

(9) To expand the understanding of the present invention, the embodiment will be further described below in combination with the drawings and the embodiment. The embodiment is only used for explaining the present invention, not limiting the protection scope of the present invention.

(10) In embodiment 1, as shown in FIG. 1 and FIG. 6: The present invention relates to a rocking chair, which comprises fabric 12, arc-shaped bottom pipes 7, a seat frame pipe 4, front foot pipes 6, armrest pipes 2, a back pipe 1, rear foot pipes 9, connecting pipes 10, seat frame connecting pieces 11, armrest supporting pipes 3 and armrest fixing pieces 5 and 8.

(11) As shown in FIG. 1, FIGS. 6a and 6b: The back ends of the armrest pipes 2 are rotatably connected with the middle part of the back pipe 1; seat frame connecting pieces 11 are fixedly arranged on the lower end of the back pipe 1 which is rotatably connected with the seat frame pipe 4 and rotatably connected with the upper parts of the rear foot pipes 9 through the seat frame connecting pieces 11; the lower parts of the rear foot pipes 9 are rotatably connected with the rear parts of the arc-shaped bottom pipes 7; one end of the connecting pipes 10 is rotatably connected with the middle parts of the rear foot pipes 9; the other end of the connecting pipes 10 is rotatably connected with the upper parts of the front foot pipes 6; the connecting point is a common rotating point of the seat frame pipe and the front foot pipes; one end of the front foot pipes 6 is rotatably connected with the front parts of the arc-shaped bottom pipes 7; the armrest fixing pieces 5 and 8 are fixed to the upper ends of the front foot pipes 6 and are rotatably connected with the seat frame pipe 4 and the connecting pipes 10 through the connecting points arranged thereon; one end of the armrest pipes 2 is rotatably connected with the back pipe 1; the other end is rotatably connected with the armrest supporting pipes 3; the lower end of the armrest supporting pipe 3 on one side is rotatably connected with the armrest fixing piece 5; the lower end of the armrest supporting pipe 3 on the other side is rotatably connected with the armrest fixing piece 8; and the fabric 12 is sleeved on the back pipe 1 and the seat frame pipe 4.

(12) As shown in FIG. 2 which is a structural comparison diagram: The rear foot pipe 1 is rotatably connected with the arc-shaped bottom pipe 3 through the fixing piece 2; the front foot pipe 4 is connected with a sliding piece 5 sleeved on the arc-shaped bottom pipe 3; the sliding piece 5 slides back and forth on the arc-shaped bottom pipe 3 to drive the front foot pipe to move; to ensure the safety of the bracket, a safety lock 6 is also required to be added to the sliding piece 5; therefore, the whole bracket has poor safety due to insufficient sliding rigidity.

(13) As shown in FIG. 3: The seat frame connecting piece 11 is fixedly installed under the back pipe 1; hinging holes in the middle of the seat frame connecting piece 11 are rotatably connected with the seat frame pipe; a lower hole is rotatably connected with the rear foot pipe 9; and the middle part of the rear foot pipe 9 is rotatably connected with one end of the connecting pipe 10.

(14) As shown in FIG. 4, FIG. 7 and FIG. 8 which is a bracket locking structure: A lock hole 3-1 is formed in the armrest supporting pipe 3; a lock is arranged on the armrest fixing piece 8; as shown in FIG. 7 and FIG. 8: the lock comprises a pressing piece 8-1, a spring 8-2 and a bolt 8-3; the spring 8-2 and the bolt 8-3 are installed on both ends of the pressing piece 8-1 to form a lever structure; under normal usage state, the spring 8-2 is stressed against the pressing piece 8-1 and a lever principle is applied to extend the head of the pin 8-3 into a clamping port of the armrest fixing piece 8; when the armrest supporting pipe 3 rotates to the pin 8-3, the pin 8-3 is ejected out by the surface and the spring 8-2 is extruded further; when the armrest supporting pipe 3 moves to the lock hole 3-1, the pin 8-3 is quickly inserted into the lock hole 3-1 under the action of spring force and the armrest supporting pipe 3 is locked; and the rotating freedom is constrained so the bracket is completely locked in the safety usage state.

(15) As shown in FIGS. 5a and 5b: After the bracket is unlocked by the safety lock, the rotating freedom between the armrest supporting pipe 3 and the armrest fixing piece 8 is released; the back pipe 1 is pulled forwards by hand; the back pipe 1 drives the rear foot pipe 9 through the seat frame connecting piece 11 fixed below to rotate in an opposite direction to the back pipe; the rear foot pipe 9, the front foot pipe 6, the connecting pipe 10 and the arc-shaped bottom pipe 7 are connected to form a quadrangle, but when the rear foot pipe 9 rotates backwards, the angle of the quadrangle is changed to drive the seat frame pipe 4 to rotate downwards and to drive the front foot pipe 6 to rotate backwards; the back pipe 1 rotates forwards; and the armrest supporting pipe 3 is driven through the armrest 2 to rotate forwards until the seat frame pipe 4 moves downwards to the arc-shaped bottom pipe 7.
