The adjustable rotary rocking chair has the following working process:

the adjusting handle 15 is pulled axially outwards to be disengaged from the round hole at one side of the chair frame connecting plate 16, and the chair frame connecting plate 16 rotates around the axis of the connecting plate rivet 20 when moving back and forth (see fig. 10a-10c) because the hole at the other side is a long hole; the adjustment handle 15 is pushed axially inward to be inserted into a circular hole in one side of the frame attachment plate 16, so that the frame attachment plate 16 and the cylinder attachment plate 18 are connected as a unit so as to be non-swingable back and forth (see fig. 9a to 9 c). Meanwhile, the spring pressure adjusting knob 22 is rotated to push the spring pressure adjusting knob to press and release the swinging spring 21 upwards through the screw thread matched with the square neck bolt 17 so as to adjust the torsion of the spring.

The adjusting handle 15 is rotated to press the cylinder valve of the cylinder 23 with its crankshaft section, so that the compressed gas in the lower cavity of the cylinder piston enters the upper cavity of the cylinder piston through the pipe wall air passage. And the cylinder barrel drives the chair frame A to descend or ascend under certain pressure (see figures 10a-10 c); when the rotary adjusting handle 15 is released, the compressed gas presses the cylinder piston against the cylinder barrel, thereby closing the pipe wall air passage. When the cylinder barrel is pressed down or lifted, the volume of compressed gas is kept unchanged when the two cavities are disconnected, so that the cylinder barrel cannot be descended or ascended, and the chair frame assembly A cannot be descended or ascended (see fig. 9a-9 c).

The process of opening and folding the handrail tube is as follows:

because the cavities of the spring seat 7 and the button seat 10 are similar shapes slightly larger than the outline of the limit slider 9. When the button is rotated, the button 11 is pressed to push the limiting slide block 9 to compress the spring 8, so that the limiting slide block 9 is completely separated from the cavity of the button seat 10, and is contacted and limited to realize rotation (see fig. 7a-7 b). After the button 11 is released, the limiting slide block 9 is tightly pressed on the button base 10 under the action of the spring 8 until the spring seat 7 is overlapped with the cavity of the button base 10, and the limiting slide block 9 enters the cavity of the button base 10. With half inside the spring seat 7 and the other half inside the button seat 10, thereby limiting the rotation of the spring seat 7 and the button seat 10 (see fig. 6a-6 b).

The operation of the foot tube locking mechanism 28 is as follows:

when the lock is unlocked (see fig. 14), the lower pin tube 29 penetrates through the circular ring of the limiting ring 37, and the circular ring of the limiting ring 37 is positioned in the opening of the lock case 34 and is clamped in the limiting groove on the inner wall of the lock case at the same time, so that the wrench 35 is stopped when the downward rotation process of the wrench is performed until the limiting ring 37 is perpendicular to the axis of the lower pin tube 29 by taking the contact point of the circular ring of the limiting ring 37 in the opening of the lock case 34 and the inner wall of the lock case 34 as the center of a circle and pressing the handle of the limiting ring 37 downward. At this time, because the inner diameter of the circular ring of the limiting ring 37 is slightly larger than the outer diameter of the lower leg tube 29, the lower leg tube 29 can penetrate through the limiting ring 37 and the lock shell 34 to enter the telescopic upper leg tube 27, and the length of the leg tube can be adjusted.

When the lock is locked (see fig. 13), the wrench 35 is rotated upwards, and at this time, the handle of the limit ring 37 tilts upwards from the horizontal state under the action of the compression spring 38 by taking the contact point of the limit ring 37 in the opening on the inner wall of the lock shell 34 and the inner wall of the lock shell 34 as the center until the inner edge of the limit ring 37 contacts with the pipe wall of the lower pin pipe 29. The wrench 35 continues to rotate upward until it is in the locked position, at which time the handle of the stop collar 37 is disengaged from the wrench 35. When the lower leg tube 29 is moved upward to retract into the telescopic upper leg tube 27, the retainer ring 37 gripping the lower leg tube 29 will move with the lower leg tube 29 toward the inside of the telescopic upper leg tube 27. Because the circular ring of the limiting ring 37 is limited by the inner wall in the lock shell 34 and cannot move inwards, the handle continuously tilts upwards under the combined action of the compression spring 38 and the inward movement force of the lower pin tube 29, the lower pin tube 29 is clamped more and more tightly, the movement of the lower pin tube 29 is limited, and the locking effect is achieved.

The folding process of the adjustable rotary rocking chair of the embodiment is as follows:

in order to reduce the packaging size and facilitate carrying, the rotary chair with the adjustable leg tube length is divided into three parts, namely a chair frame assembly A, an adjusting mechanism B and a leg tube assembly C. When the chair frame assembly A is folded, the left hand and the right hand simultaneously press the button 11 to enable the upper handrail stand pipe 6 and the lower handrail stand pipe 12 to be close to each other, and the back pipe 4 and the overturning seats 3 at the two ends of the back pipe rotate inwards together to enable the back pipe 4 to be attached to the circular pipe of the seat frame 14.

The adjusting mechanism B is connected with the chair frame assembly A through a bolt, and the chair frame assembly A is lifted upwards when folded, so that the air cylinder connecting plate 18 is pulled out of the air cylinder barrel of the air cylinder 23, and the adjusting mechanism B is separated from the foot pipe assembly C.

When the leg tube assembly C is folded, the wrench 35 in the locking mechanism 28 is first pulled down to the limit position, so that the limiting iron ring 37 is perpendicular to the axis of the lower leg tube 29, and the lower leg tube 29 is pushed upward to retract into the telescopic upper leg tube 27 until the universal foot pad 30 contacts the locking mechanism 28. The cross-pull rod seat fixing tube 32 is pushed upwards to drive the cross-pull rod 31 to be folded inwards, and simultaneously the cross-pull rod 31 pulls the telescopic upper foot tube 27 connected with the other end to be folded inwards together, so that the folding effect is achieved. Otherwise open.

The above is the preferred embodiment of the present invention, and the protection scope of the present invention is not limited, and the deformation and improvement made by the design idea of the present invention for those skilled in the art should be considered as the protection scope of the present invention. More specifically, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, other uses will also be apparent to those skilled in the art.
