Detailed description of the invention
Below in conjunction with the accompanying drawings the design is described in detail:
See Fig. 1: one and backstitch auto lifting back support apparatus, including cylinder 1, mechanical valve assembly 14, lift lever 6, riser 8 and rear dragging wheel assembly 10, valve one 1-1 and deafener 1-2 it is provided with on described cylinder 1, described cylinder 1 is fixed in casing by air cylinder support 2, the cylinder connector 3 of described cylinder 1 is fixed by the left end of axial screw 1 with lift lever 6, the right-hand member of lift lever 6 is flexibly connected with the upper end of riser 8 by axial screw 37, and riser 8 lower end is connected with rear dragging wheel assembly 10 by axial screw 49；It is provided with cylinder fixing threaded hole 2-2 and lift lever fixing threaded hole 2-1(on described air cylinder support 2 and sees Fig. 3), described lift lever 6 is fixed on the lift lever fixing threaded hole 2-1 of air cylinder support 2 by axial screw 25, rotates with axial screw 25；
See Fig. 2: described mechanical valve assembly 14 is fixed on cabinet rear by mechanical valve installing plate 15, mechanical valve assembly 14 includes mechanical valve roller 14-1 and two valve two 14-2, described mechanical valve roller 14-1 and the joining distal ends backstitching spanner 13 touch, and two valve two 14-2 are connected with valve one 1-1 and the source of the gas of cylinder 1 by trachea 1 and trachea 2 12 respectively.
nullThe work process of utility model: backstitch spanner 13 and press，Mechanical valve roller 14-1 compresses with the motion backstitching spanner 13，Mechanical valve 14 work conducting，Mechanical valve 14 is connected with cylinder 1 by trachea 1，Cylinder 1 now is in the state of stretching out，Cylinder 1 is fixed on air cylinder support 2 by cylinder fixing threaded hole 2-2，Cylinder 1 stretches out，Cylinder connector 3 moves downward，Cylinder connector 3 and lift lever 6 are fixedly connected by axial screw 1，Lift lever 6 is coordinated with lift lever fixing threaded hole 2-1 by axial screw 25 and is fixed on air cylinder support 2，Rotate around axial screw 25，Lift lever both sides arm of force ratio is 5: 3，Cylinder 1 is fully extended，Lift lever 6 is driven to rotate，Riser 8 upper end is linked with lift lever by axial screw 37，Cylinder moves downward drive riser 8 and moves upward to peak，Riser 8 lower end is linked with rear dragging wheel assembly 10 by axial screw 49，Now，Rear dragging wheel assembly 10 is raised to extreme higher position under the effect of riser 8.
When backstitching end, backstitching spanner 13 and unclamp and return in situ, mechanical valve 14 is become clutch state from impaction state, and mechanical valve is closed, and cylinder 1 is returned to initial contraction state under rear dragging wheel stage clip effect, and rear dragging wheel assembly is also preferably minimized, and starts again to pull work feed.
