Embodiment
For the ease of the understanding of those skilled in the art, the utility model is made below in conjunction with the drawings and specific embodiments into
One step is described in detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of cylinder of adjustable stroke, including cylinder barrel 1, cylinder barrel 1 is interior to be provided with along cylinder
The piston 3 and limited block 2 that cylinder 1 slides, piston 3 are connected with cylinder rod 4, and piston 3 slides in cylinder barrel 1, so as to drive cylinder rod 4 to stretch out
Or retraction.Limited block 2 is connected with apparatus for adjusting position 6, and apparatus for adjusting position 6 adjusts position of the limited block 2 in cylinder barrel 1, from
And the scope of activities of piston 3 is limited, and then limit the stroke of cylinder rod 4.Spring 5 is additionally provided with cylinder barrel 1, the both ends of spring 5 are supported respectively
In on the front end of cylinder barrel 1 and piston 3, piston 3 resets under the elastic force effect of spring 5.
Apparatus for adjusting position 6 includes the adjusting rod 61 being connected with limited block 2, and cylinder barrel 1 is provided with the card of secured adjusted bar 61
Tight mechanism 62.Clamping body 62 includes the fixed block 621 being fixed on cylinder barrel 1, and fixed block 621 is provided with and is no less than an activity
Claw 622, adjusting rod 61 are provided with the annular spacing groove 611 coordinated with movable jaw 622.The cross section of annular spacing groove 611
For right-angled trapezium.Fixed block 621 is provided with rotating shaft, and movable jaw 622 is fixed in rotating shaft and rotated around the axis.Adjusting rod 61 to
When lower movable, because the cross section of annular spacing groove 611 is right-angled trapezium, it may be such that movable jaw 622 automatically and annular stop
Groove 611 departs from, and when adjusting rod 61 is movable upwards, using pressed by external force movable jaw 622, movable jaw 622 is departed from annular limit
Position groove 611, unclamps movable jaw 622 when regulation is completed, movable jaw 622 is caught in annular spacing groove automatically under gravity
In 611.
