In cavity.
Preferably, the adjustment seat is connected with the cylinder block inwall by guide pad.
Preferably, guide ring is provided with the cylinder block, leading in the adjustment seat is embedded on the inside of the guide ring
Into groove, outside is close to connect with cylinder block inwall.
Preferably, the fixed seat is connected with the adjustment seat by closely-pitched triangle thread.
A kind of mechanical increased stroke-adjustable gas cylinder provided by the invention, by adjusting the position of regulating block, joystick away from
From the Stroke Control of cylinder is realized, cylinder gas consumption is saved meet flexible modulation stroke while, while gas can also be reduced
Body was full of by the time of shielding stroke, improved efficiency.In addition, the mechanical increased stroke-adjustable gas cylinder of present invention offer is rational in infrastructure, adjust
Section is convenient, and Stroke Control is accurate, can the workpiece that differs of corresponding sizes, can be reduced for client purchase the quantity reduction of cylinder into
This.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
As shown in figure 1, a kind of mechanical increased stroke-adjustable gas cylinder provided by the invention, including：
Cylinder block 1；
The left end of cylinder block 1 is equipped with the first end cap 2, and right-hand member is provided with the second end cap 3；
Fixed seat 4, adjustment seat 5, handle 7 and piston 6 are provided with the cylinder block 1；
The fixed seat 4 is fixed on first end cap 2；The first cavity 8, the tune are provided with the fixed seat 4
The one end of seat 5 is saved to insert in first cavity 8；
The second cavity 9 is provided with the adjustment seat 5；Described one end of handle 7 is connected with the piston 6, other end insertion
In second cavity 9.
Above-mentioned technical proposal, by adjusting the position of regulating block, the distance of joystick 7 realizes the stroke control of cylinder
System, while flexible modulation stroke is met save cylinder gas consumption, while can also reduce gas be full of by shielding stroke when
Between, improve efficiency.In addition, the present invention provides, mechanical increased stroke-adjustable gas cylinder is rational in infrastructure, and easy to adjust, Stroke Control is accurate,
The workpiece that sizes differ can be corresponded to, can be that the quantity of client's reduction buying cylinder reduce cost.
It should be noted that adjustment seat 5 includes two parts, respectively narrow end and wide end, the of narrow end insertion fixed seat 4
In one cavity 8, wide end is bonded with the inwall of cylinder block 1；In addition, the wide end of adjustment seat 5 is connected by guide pad with cylinder block 1.
In the present embodiment, adjustment seat 5 is connected with the inwall of cylinder block 1 by guide pad 10；Its guiding of guide pad 10 is made
With,.
In the present embodiment, guide ring 11 is provided with cylinder block 1, the inner side of guide ring 11 is embedded in adjustment seat 5
In guide groove, outside is close to connect with the inwall of cylinder block 1.Guide ring 11 plays support guide effect, prevents adjustment seat 5 from moving
When discontinuity and with wall friction in cylinder block.
In the present embodiment, fixed seat 4 is connected with adjustment seat 5 by closely-pitched triangle thread.Closely-pitched triangle thread spiral shell
Away from small, lift angle is small, and self-locking property is more preferable, effectively prevents vibration or varying load, also fine-tuning.
Mechanical increased stroke-adjustable gas cylinder provided by the invention, the piston 6 of cylinder are run in round trip, when cylinder is turned left
During operation, right side inflation, final gas consumption V1=cylinders inner section product A × round trip × inner gas pressure, when piston 6 is turned right
During motion, final gas consumption V2=cylinders inner section product A × round trip × inner gas pressure.Therefore the round trip of piston 6
Gas consumption V=V1+V2.It follows that piston 6 first need not be full of by shielding stroke when acting to the left, reduce unnecessary fill
The gas time, improve operating efficiency.
