The slider spring 736 is mounted within the hinge 731 by a spring seat 39 on the inner wall of the hinge 731.
The working process and principle of each structure of the invention are described in detail as follows:
when the rotary hinge 5 is in use, the telescopic support leg assembly 6 of the fishing chair is in an opened state, the limiting block 57 is positioned in the positioning groove 513 on the inner wall of the fixed outer barrel 53, and the limiting block 57 is always positioned in the first sliding groove 512 of the rotary inner barrel 52, so that the limiting block 57 locks the relative positions of the fixed outer barrel 53 and the rotary inner barrel 52, the rotary inner barrel 52 cannot rotate relative to the fixed outer barrel 53, and the telescopic support leg assembly 6 of the fishing chair cannot rotate relative to the seat 2; when the rotation is needed, the button 55 is pressed, and the button 55 is abutted with the other end of the limiting block 57, so that the limiting block 57 moves towards the fixed outer cylinder 53 until being separated from the positioning groove 513 and positioned in the inner wall of the fixed outer cylinder 53, and the limiting block 57 can rotate randomly in the fixed outer cylinder 53 because the inner diameter of the upper end cylinder of the fixed outer cylinder 53 is larger than the length dimension of the limiting block 57, at the moment, the fixed outer cylinder 53 is not locked with the rotating inner cylinder 52 any more because the limiting block 57 is separated from the positioning groove 513, and at the moment, the rotating inner cylinder 52 can rotate relative to the fixed outer cylinder 53, and the telescopic support leg assembly 6 of the fishing chair can rotate relative to the seat 2; due to the mutual positional relationship of the track groove 514, the stopper, and the arc stopper 515, the rotary inner cylinder 52 can be rotated by a certain angle with respect to the fixed outer cylinder 53, and cannot be rotated by any angle.
When the telescopic support leg assembly 6 is used, in a default state, under the action of the spring 67, one end of the upper pulling piece 651 of the thrust ring 65 is lifted upwards, so that the thrust ring 65 is attached to the inclined surface of the lower bottom surface of the upper pipe 630 to be in an inclined state, the inner hole of the thrust ring is contacted with the annular groove of the telescopic rod 62, the telescopic rod 62 is blocked, and the telescopic rod 62 cannot slide up and down; when the length of the telescopic rod 62 needs to be adjusted, the sliding sleeve 66 is shifted downwards, the sliding sleeve stop block 611 at the inner side of the sliding sleeve 66 drives the shifting block 651 at the side surface of the thrust ring 65 to move downwards, the thrust ring 65 is shifted to a horizontal state, the inner diameter of the thrust ring 65 is larger than the outer diameter of the telescopic rod 62, the thrust ring 65 does not clamp the telescopic rod 62 any more, the telescopic rod 62 at the moment can slide up and down, when the telescopic rod 62 is adjusted to a proper position, the sliding sleeve 66 is loosened, and the thrust ring 65 is reset under the action of the spring 67 and is in contact with the telescopic rod 62 in an inclined state again and is clamped, so that the adjustment process is completed.
In use, in the open position, the tab 735 is positioned in the rectangular slot 734 and the button of the bar slider 732 is positioned in the button aperture 737, locking the relative positions of the headrest 72 and the seatback 71; when the headrest 72 needs to be folded, the bar-shaped slide block 732 is pressed down, so that the button of the bar-shaped slide block 732 is separated from the button hole 737 inwards, at the moment, the protruding blocks 735 on two sides of the bar-shaped slide block are separated from the rectangular sliding groove 734 and are positioned in the inner cavity of the connecting pipe 730, at the moment, the hinge piece 731 can freely rotate relative to the connecting pipe 730, and at the moment, the headrest 72 can be stored and folded; when the back rest 72 is required to be opened, the back rest 72 is reversely rotated, because the bar-shaped sliding block 732 always bears the outward thrust of the sliding block spring 736, when the bar-shaped sliding block 732 rotates to the position of the button hole 737, the protruding block 735 enters the rectangular sliding groove 734, the button enters the button hole 737, and the back rest 72 cannot rotate, namely, the back rest 72 is in the opened position.
The fishing chair of the invention is stored as follows:
the sliding sleeve 66 is moved downwards to retract the telescopic support leg assembly 6 to a proper length, then the button 55 on the rotary hinge 5 is pressed, the telescopic support leg assembly 6 is rotated, the telescopic support leg assembly 6 is positioned on the lower side of the seat 1, the transverse support plate 3 is stored in the storage groove, and then the chair back assembly 7 is rotated to be flush with the seat 1 and positioned on the upper side of the seat 1, so that the whole storage process is completed.
