Working principle and process of the present invention:

Height adjustment: pull the pull rod 67 through the tie wire, the pull rod 67 drives the cam 64 to rotate clockwise, the cam 64 drives the convex valve stem adjustment plate 63 to rotate clockwise, when the convex valve stem adjustment plate 63 rotates clockwise, the height control valve 62 One valve stem 621 is located on the convex arc surface 631, and the other valve stem 621 is located on the arc convex edge 632, so that the height control valve 62 inflates the gas spring 5, thereby adjusting the rise of the suspension height of the seat;

When the pull rod 67 is stopped, the cam 64 will turn back counterclockwise under the action of the spring, and the cam 64 will drive the convex valve stem adjustment plate 63 to turn back counterclockwise. When the convex valve stem adjustment plate 63 turns counterclockwise One of the valve stems 621 of the height control valve 62 is located on the arc convex edge 632, and the other valve stem 621 is located on the convex arc surface 631, and the gas spring 5 deflates, thereby adjusting the suspension height of the seat.

Suspension adjustment: When the pull rod 67 is stuck on the stopper 681 of the base plate 68 and does not move, when the seat is lowered, that is, when the passenger is heavy, the cam 64 slides down and breaks away from the support of the convex valve stem adjustment plate 63, and the convex valve stem The adjustment plate 63 rotates clockwise, one of the valve stems 621 of the height control valve 62 is positioned on the convex arc surface 631, and the other valve stem 621 is positioned on the arc convex edge 632, so that the height control valve 62 inflates the gas spring 5, and then the seat is adjusted. The lift of the seat suspension height; when the seat is raised, that is, when the passenger is lighter, the cam 64 rises and breaks away from the support of the convex valve stem adjustment plate 63, and the convex valve stem adjustment plate 63 rotates counterclockwise, and the height control valve 62 among them One valve stem 621 is located on the arc convex edge 632, and the other valve stem 621 is located on the convex arc surface 631, and the air spring 5 is deflated, thereby adjusting the suspension height of the seat.
