It is rotated in base connector 33, and when the angulation change of seat connection 31, base connector 33 can be driven to occur to turn
It is dynamic.
Preferably, seat connection 31 includes operating side 311 and the first threaded ends 312, and operating side 311 is in seat
The front end of chair ontology 1, with convenient for users to being operated to seat connection 31.Base connector 33 include gag lever post 331 with
And second threaded ends 332, gag lever post 331 is slidably and rotatably set to pedestal position-limited rail 32, so that gag lever post 331 can
Move up and down, can also rotation, the rotary shaft of gag lever post 331 and the rotary shaft of seat connection 31 are mutually perpendicular to.Second screw thread connects
332 radially extending along gag lever post 331 of end are connect, and are threadedly coupled with the first threaded ends 312.
First threaded ends 312 have external screw thread, and the second threaded ends 332 have one to prolong along 331 radial direction of gag lever post
The through-hole stretched, the through-hole have and the matched internal screw thread of the first threaded ends 312.
Preferably, angle stepless regulating mechanism 3 includes two pedestal position-limited rails 32, and two pedestal position-limited rails 32 are separately positioned on bottom
The left and right sides of seat 2.Pedestal position-limited rail 32 has vertically extending sliding slot 320, and the sliding slot 320 of two pedestal position-limited rails 32 is opposite,
The both ends of gag lever post 331 extend respectively into sliding slot 320, and the outer diameter of gag lever post 331 is matched with the internal diameter of sliding slot 320, so that
Gag lever post 331 rotation and 320 can move up and down along the chute in sliding slot 320, while the displacement in the horizontal direction of gag lever post 331
It is limited by sliding slot 320.
Fig. 3,4 show that seat body 1 turns to the second tilt angle by the first tilt angle, change to Fig. 4 by Fig. 3,
Rotary seat connector 31 first tilts seat connection 31 relative to base connector 33 and moves forward, seat connection
31 front end drives 1 forward slip of seat body and rotates, while driving 331 slide downward of gag lever post and rotating.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
