With reference to fig. 1-16, the specific operation of the chair 200 of the present invention during the angle adjustment and folding process is as follows:
when the angle of the backrest 202 needs to be adjusted, the backrest operating part 205 is moved to rotate, and the steel wire 206 drives the driving member 203 to slide, so that the driving member 203 drives the engaging pin to disengage from one of the engaging holes 21; then, the backrest 202 is rotated relative to the seat plate 201 to adjust the angle, after the angle adjustment of the backrest 202 is completed, the backrest operation part 205 is released, the backrest operation part 205 is reset under the action of the elastic restoring force of the third elastic member 207, and meanwhile, the driving member 203 is reversely slid and reset under the action of the elastic restoring force of the third elastic member 207, so as to drive the locking pin 204 to slide to be engaged with another engaging hole 21, thereby locking the angle of the backrest 202 adjusted relative to the seat plate 201. In the process of rotating the backrest 202 relative to the seat board 201, if the angle adjusted by the backrest 202 is too large, that is, the backrest 202 rotates to the folded direction to adjust the angle of the backrest 202 by too large angle, the rotation of the backrest 202 can drive the rotating part 1 to rotate relative to the fixed part 2, the linkage part 3 can be blocked by the locking part 4 in the sliding process, so that the linkage part 3 can not continue to slide, thereby limiting the rotating angle of the rotating part 1 relative to the fixed part 2, thereby avoiding accidental folding when the rotating part 1 rotates to adjust the angle relative to the fixed part 2, and improving the safety when the angle is adjusted by rotation.
When the backrest 202 needs to be folded, the locking body 41 drives the blocking portion 42 to slide by pressing the unlocking operation portion 44 of the locking member 4, so that the blocking portion 42 is separated from blocking the linkage member 3, and the linkage member 3 is not blocked; then, by rotating and folding the backrest 202 with respect to the seat plate 201, the linking member 3 can slide with respect to the fixing member 2 and can pass through the groove 411 of the locking member 4, and at this time, the linking member 3 can keep a state of being engaged with the groove 411 of the locking member 4, or the linking member 3 can pass through and be disengaged from the state of being engaged with the groove 411.
In summary, when the rotating member 1 rotates relative to the fixed member 2 to adjust the angle of the backrest 202 relative to the seat plate 201, the seat 200 of the present invention drives the linking member 3 to slide relative to the fixed member 2, and because the locking member 4 is provided in the present invention, the linking member 3 is blocked by the blocking portion 42 of the locking member 4 during the sliding process, so that the linking member 3 cannot slide continuously, and the rotation of the rotating member 1 relative to the fixed member 2 is limited, thereby preventing the rotating member 1 from folding accidentally when rotating relative to the fixed member 2 to adjust the angle, and improving the safety when rotating to adjust the angle; when the rotating member 1 and the fixed member 2 need to be folded, the locking member 4 slides relative to the fixed member 2, so that the locking release portion 43 releases the locking of the linkage member 3, and the linkage member 3 can continue to slide, so that the rotating member 1 can continue to rotate relative to the fixed member 2, and the backrest 202 and the seat plate 201 can be folded.
The above disclosure is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, so that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
