Figure 11 is the broken section structural representation of intersection support bar mechanism 7;
Figure 12 intersects the A of support bar mechanism 7 to structural representation;
It is how as follows with reference to accompanying drawing narration open side type: when desktop need raise with the course of work of adjustable health care table, the U-shaped of stepping on actuation mechanism (3) that tramps with one's feet is down stepped on bar, make to drive oil pump (2) to hydraulic cylinder (5) fuel feeding, piston rod (201) heads on desktop and rises under the oil pressure effect; After desktop rises to desired height, unclamp the U-shaped of stepping on actuation mechanism (3) and step on bar, desktop just is parked in desired location.
When desktop need reduce height, treading wheel (408) tramps with one's feet down, the cross-drilled hole (404) of valve rod is connected with fuel feed hole (402), and pressure oil release in the table post (5) at this moment and process oil pipe (418), fuel feed hole (402), cross-drilled hole (404), vertical hole (405), outage (410) flow in the oil storage tank (103).
With reference to Fig. 7, Fig. 8, Fig. 9, Figure 10, one end can inject and pull out the control pin (601) of the gathering sill (505) of a column piston bar (503), pack in the control key seat (602) on the lasso of a post (5) top, the middle part of control pin (601) is provided with the pin platform, on the pin platform spring (606) is housed, control pin (601) one ends inject gathering sill (505), the other end passes the lid (603) that is screwed on the control key seat (602), on the exposed junction of control pin (601), be provided with square neck (609), a pull handle (613) that is provided with square hole be fastened on the square neck (609) with nut (611).
Lid (603) is a cylindrical structure that central dividing plate is arranged, and its outer face is provided with dark vertical slot (607) and shallow translot (608), and the center of circle that vertical slot and translot are crossed lid (603) intersects vertically.To cover (603) with locking nut (604) is locked on the control key seat (602).
Fig. 9 is the structural representation that control pin (601) inserts piston rod gathering sills (505), and under this state, piston rod (503) and the desktop that is connected the piston rod top all are in the lock state, and can not rotate; If pull handle (613) is outwards pulled out, the pull handle (603) that control pin (601) outer end is installed breaks away from vertical slot (607), and then pull handle is rotated 90 ° loose one's grip, and then pull handle is subjected to the elastic force of spring (606) to be retracted into translot (608).Because translot is more shallow than vertical slot, so control pin (601) just is drawn out, the gathering sill (505) that has broken away from piston rod (503), at this moment piston rod (503) and the desktop that is connected on the piston rod all are in released state, and desktop (9) can rotate corresponding orientation with staff's seating position.
Figure 10 is the structural representation that control pin (601) is pulled out gathering sill (505), and under this state, desktop (9) can turn to the orientation that the staff suits.
With reference to Figure 11, Figure 12, pole lower wall (701) is connected a top of column piston bar (503) with flat key (504), respectively the two ends up and down of inner supporting rod (703), outer pole (704) are connected on the pin-and-hole of the last dish of pole (702), pole lower wall (701) with bearing pin (707), composition can change the crossing branching rod mechanism at desktop inclination angle.When desktop need change level, when being transformed into required angle, alignment pin (706) is inserted in the corresponding hole (701) that inside and outside pole going up be provided with, just desktop (9) can be adjusted to suitable inclination operating position.The adjustment effect at desktop (9) angle of inclination, this state, suitable especially design, drawing personnel use, and have expanded the scope of application.
When needs change the specification of desktop (9),, change required supporting desktop and get final product former desktop dismounting.Enforcement of the present utility model has outstanding feature and positive effect.
