It is connected on threaded portion.
In this way, threaded portion does not interfere with movement of the moving lever 30 between cylinder body 10, and setting can be stablized and adjusted
Part 32 and fixing piece 34 are saved, while being also convenient for adjusting the position of regulating part 32 and fixing piece 34, realizes the adjusting of cylinder stroke.
In some embodiments, regulating part 32 is provided with cushion pad 31 close to 10 side of cylinder body.
In this way, moving lever 30 drives regulating part 32 to move, and when so that regulating part 32 is hit 10 outer wall of cylinder body, cushion pad 31
The intensity of shock can be substantially reduced, the influence hit to 100 structural stability of stroke adjustable cylinder is reduced, decreases regulating part
32 extent of damage extends the service life of regulating part 32.
Specifically, cushion pad 31 in present embodiment using nylon material and cushion pad 31 size and regulating part 32
Size is identical.
In some embodiments, 20 both sides of limited block are respectively arranged with cylinder body 10 on the moving direction of limited block 20
Inner wall cooperation crash roll 24.
In this way, when moving lever 30 drives limited block 20 to be moved in cylinder body 10, limited block 20 and moving direction upper cylinder body 10
Both ends inner wall when being in contact, crash roll 24 greatly reduces the vibration and loss that contact generates, and extends making for cylinder body 10
Use the service life.
In some embodiments, it is provided with anti-skid structure on regulating part 32.
In this way, when operating personnel adjust the position of regulating part 32, anti-skid structure reduces the hand and regulating part of operating personnel
Slippery conditions between 32 improve the convenience of adjusting, keep the stroke adjustment in present embodiment more humane.
A kind of processing unit (plant) (not shown), which is characterized in that the stroke adjustable cylinder including any embodiment as above
100。
In the utility model embodiment, it is located at the position on moving lever 30 by adjusting regulating part 32, so that fortune
When lever 30 is moved to range, limitation moving lever 30 moves, and realizes the stroke adjustment of moving lever 30, makes present embodiment
In processing unit (plant) can be applied to it is more multi-environment in.
In the description of this specification, reference term " embodiment ", " certain embodiments ", " schematically implementation
What the description of mode ", " example ", " specific example " or " some examples " etc. meant to describe in conjunction with the embodiment or example
