Utility model works process:
A kind of built-in pressure regulator valve vertical hydraulic jack of the utility model during the work time, when using the jack
When, pedestal 1 can be laid flat on the ground, the holding end of hand 13 is pressed in lift then up, presses the top of hand 13 with support rod 19
Upper end be fulcrum and rotate, the side for pressing hand 13 pulls out the plunger in the pump housing 6 upwards, at this time the check valve on the first oil duct 8
It opens, the closed check valve on the second oil duct 9, the oil liquid in shoe cream room 5 is inhaled into the pump housing 6 by the first oil duct 8, then
Hand 13 is pressed in pressing, presses the plunger depression in the drive pump housing 6 of hand 13, at this time the closed check valve on the first oil duct 8, the second oil duct 9
On check valve open, the oil liquid in the pump housing 6 is driven into oil cylinder 3 by the second oil duct 9 is pushed up piston rod 4,
Slide bar 172 is hauled rising by transverse slat by piston rod 4, and the limited block 173 of 172 side of slide bar will be with the outer end of gag lever post 176
It collides, since the top of limited block 173 is designed in slope shape, the bottom of the outer end of gag lever post 176 is designed in scarf, is made
It obtains gag lever post 176 to be under pressure and be retracted in limit hole 175, allows slide bar 172 smoothly to increase, when limited block 173
After crossing gag lever post 176, spring 178 pushes gag lever post 176 to reset, when the lifting weight of piston rod 4 is excessive, in oil cylinder 3
Pressure value will be greater than pressure regulator valve 11 setting value, the hydraulic oil in the second oil duct 9 will be returned to from pressure regulator valve 11 at this time
It in first oil duct 8 rather than continues into oil cylinder 3, effectively jack is avoided to damage because of overload, when under 4 accident of piston rod
When drop, the strength of decline can be passed to slide bar 172 by transverse slat by piston rod 4, since spring 178 has pushed gag lever post 176 multiple
The top of the bottom surface and gag lever post 176 of position and limited block 173 is horizontal plane contact, and gag lever post 176 is enabled to stop to limit
Position block 173 declines, prevent slide bar 172 is from declining, prevent piston rod 4 is from declining, if necessary to deliberately make piston rod 4 suitable
If benefit decline, so that it may which rotation adjusts bolt 179, adjusts bolt 179 and the horizontal sliding in sleeve 171 of sliding block 174 is pulled to make
It obtains the distance between sliding block 174 and slide bar 172 to become larger, prevent gag lever post 176, from being in contact with limited block 173, piston rod 4 is
It can freely decline, since housing 2 and pedestal 1 weld, the firmness that housing 2 is connect with pedestal 1 be improved, due to the pump housing 6
It is welded with pedestal 1, improves the firmness that the pump housing 6 is connect with pedestal 1, rotated due to pressing the upper end of plunger of hand 13 and the pump housing 6
Connection, support rod 19 are connect with the outer ring rotating of bearing 18, so that pressing hand 13 can be around the plunger of the pump housing 6 with support rod 19
360 ° of rotations, improve the flexibility used, compared with prior art, can effectively promote the connection of housing, the pump housing and pedestal
Firmness, effectively prevent piston rod to decline suddenly and cause security risk, effectively prevent jack overload damage, it is ensured that it is very heavy
Push up work in rated range, can flexible rotating press hand, extend the service life of jack.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new
Scheme after type simple transformation belongs to the protection scope of the utility model.
