Description
Technical field
The utility model is related to hydraulic cylinder technical field, especially a kind of optional automatic locked hydraulic cylinder of dual thrust.
Background technology
Hydraulic cylinder be hydraulic energy is changed into mechanical energy, the hydraulic pressure that does straight reciprocating motion (or pendulum motion) executes member
Part.Its simple in structure, reliable operation.Deceleration device when realizing reciprocating motion, can be removed from it, and do not have drive gap,
Stable movement, therefore be used widely in the hydraulic system of various machineries.Hydraulic cylinder power output and piston effective area and
The pressure difference on its both sides is directly proportional；Hydraulic cylinder substantially by cylinder barrel and cylinder cap, piston and piston rod, sealing device, buffer unit with
Exhaust apparatus forms.For buffer unit with exhaust apparatus depending on concrete application occasion, other devices are then essential.
Hydraulic cylinder in the prior art, coupling mechanism force are fixed, and can not be adjusted, operation flexibility is poor.
Utility model content
The applicant is directed to the disadvantage in above-mentioned existing production technology, and it is optional automatic to provide a kind of dual thrust reasonable for structure
Locked hydraulic cylinder, so as to change coupling mechanism force, work is flexible, and use reliability is good.
Technical solution used by the utility model is as follows：
A kind of optional automatic locked hydraulic cylinder of dual thrust, including cylinder barrel, the cylinder barrel is interior to be equipped with piston by sealing ring
Bar is provided with step on the piston rod, is cased with auto lock actuator on step surface in its back-end, after the piston rod
End is also equipped with coupling mechanism force and adjusts drive block, and the inner face that the coupling mechanism force adjusts drive block is abutted with auto lock actuator,
The coupling mechanism force adjusts the external installation gland of drive block and rear end cap, the gland are pressed on cylinder barrel；On the rear end cap
Portion is provided with fuel feed hole, and outlet and the coupling mechanism force of fuel feed hole adjust drive block rear end face and dock.
As a further improvement of the above technical scheme：
The auto lock actuator is disk spring group.
The beneficial effects of the utility model are as follows：
The utility model is compact-sized, reasonable, easy to operate, and drive block is adjusted by installation locking power on the piston rod
Effect, it may be convenient to the switching for realizing low coupling mechanism force hydraulic cylinder and high coupling mechanism force hydraulic cylinder, according to the need of practical application
It asks, using flexible is good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram under the utility model locking state.
Wherein：1, piston rod；2, cylinder barrel；3, auto lock actuator；4, gland；5, coupling mechanism force adjusts drive block；6, into
Oilhole；7, rear end cap.
Specific implementation mode
Below in conjunction with the accompanying drawings, illustrate specific embodiment of the present utility model.
As shown in Figure 1, the optional automatic locked hydraulic cylinder of the dual thrust of the present embodiment, including cylinder barrel 2, cylinder barrel 2 are interior by close
Seal is equipped with piston rod 1, and step is provided on piston rod 1, and auto lock actuator 3 is cased on step surface in its back-end,
The rear end of piston rod 1 is also equipped with coupling mechanism force and adjusts drive block 5, and coupling mechanism force adjusts the inner face of drive block 5 and auto lock drives
Moving part 3 abuts, and coupling mechanism force adjusts the external installation gland 4 of drive block 5 and rear end cap 7, gland 4 are pressed on cylinder barrel 2；Rear end cap
7 tops are provided with fuel feed hole 6, and outlet and the coupling mechanism force of fuel feed hole 6 adjust 5 rear end face of drive block and dock.
Auto lock actuator 3 is disk spring group.
In actual use, normal operating condition, if as shown in Figure 1, application scenario needs high coupling mechanism force, at this point,
Oil inlet at fuel feed hole 6, entering for fluid push coupling mechanism force adjusting drive block 5 to be moved to the left, disk spring group are compressed, to make it
With higher coupling mechanism force, as shown in Figure 2.According to work on the spot demand, great coupling mechanism force is needed, is into how much fluid just
Can, it is flexible and convenient to use.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is within the protection scope of the utility model referring to claim, can make any type of modification.
