Abstract
The utility model discloses a kind of hydraulic locking cylinder mechanism, it includes cylinder and piston rod, the both ends of the cylinder are respectively and fixedly provided with end cap, the piston rod is arranged in the cylinder, wherein, butterfly spring is installed outside in the piston rod in the cylinder, the butterfly spring side is provided with the tightening sleeve in cylinder, the tightening sleeve has the endoporus of taper, tighten up to be placed on outside the piston rod described in cooperation and the tapered sleeve in the endoporus is installed, locking control chamber is formed between the tightening sleeve and the cylinder, locking control port is offered on the cylinder.Above-mentioned hydraulic locking cylinder mechanism, which does not need hydraulic cylinder to provide any extrapolability, can ensure piston rod and load lock at the desired position.It is not only simple in structure, it is easy to accomplish;It is safe and reliable to operation and energy consumption is small.
Description
Technical field
A kind of hydraulic cylinder is the utility model is related to, more particularly, to a kind of hydraulic locking cylinder mechanism.
Background technology
Hydraulic jack is that hydraulic energy is changed into mechanical energy, does the hydraulic pressure execution of straight reciprocating motion (or oscillating motion)
Element.Its simple in construction, reliable operation.During with it to realize reciprocating motion, deceleration device can be removed from, and without between transmission
Gap, stable movement, therefore be used widely in various mechanical hydraulic systems.
It is well known that in the application process of hydraulic cylinder, some special occasions need to pin the position of piston rod, therefore
Need to be provided with retaining mechanism on hydraulic cylinder again.The existing retaining mechanism generally existing for hydraulic cylinder is complicated, energy consumption
The shortcomings that big and reliability difference.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic locking cylinder mechanism, have it is simple in construction, without extrapolability and
The characteristics of stable and reliable operation, to solve above mentioned problem existing for hydraulic locking cylinder mechanism in the prior art.
To use following technical scheme up to this purpose, the utility model:
A kind of hydraulic locking cylinder mechanism, it includes cylinder and piston rod, and the both ends of the cylinder are respectively and fixedly provided with end cap, described
Piston rod is arranged in the cylinder, wherein, butterfly spring, the butterfly bullet are installed outside in the piston rod in the cylinder
Spring side is provided with the tightening sleeve in cylinder, and the tightening sleeve has the endoporus of taper, is tightened up described in cooperation described in being placed on
The tapered sleeve in the endoporus is installed outside piston rod, locking control chamber, institute are formed between the tightening sleeve and the cylinder
State and locking control port is offered on cylinder.
Especially, spring housing is provided with outside the piston rod, the butterfly spring is arranged at outside the spring housing.
Especially, stop collar is fixed with the end cap of inner end in two end caps, the tapered sleeve passes through the stop collar
It is spacing with spring housing.
Especially, dust ring and lip-type packing are provided between the stop collar and the piston rod.
The beneficial effects of the utility model are that the hydraulic locking cylinder mechanism does not need hydraulic cylinder to carry compared with prior art
It can ensure piston rod and load lock at the desired position for any extrapolability.It is not only simple in structure, it is easy to accomplish;And
Energy consumption is small, safe and reliable to operation.
Brief description of the drawings
Fig. 1 is the structural representation for the hydraulic locking cylinder mechanism that the utility model embodiment 1 provides.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1, Fig. 1 is the structure for the hydraulic locking cylinder mechanism that the utility model embodiment 1 provides
Schematic diagram.
In the present embodiment, a kind of hydraulic locking cylinder mechanism includes cylinder 1 and piston rod 2, and the both ends of the cylinder 1 are fixed
There is end cap 3, the piston rod 2 can be movably arranged in the cylinder 1, and spring housing 4 is provided with outside the piston rod 2, described
In being provided with butterfly spring 5 outside the spring housing 4 in cylinder 1, the side of butterfly spring 5 is provided with the receipts in cylinder 1
Tight set 6, the tightening sleeve 6 have the endoporus of taper, coordinate the tightening sleeve 6 to be provided with outside positioned at described in the piston rod 2
Tapered sleeve 7 in endoporus, stop collar 8 is fixed with the end cap of inner end in two end caps 3, the tapered sleeve 7 passes through described spacing
Set 8 and spring housing 4 are positioned.
Locking control chamber 9 is formed between the tightening sleeve 6 and the cylinder 1, locking control oil is offered on the cylinder 1
Mouth 10.Dust ring 11 and lip-type packing 12 are provided between the stop collar 8 and the piston rod 2.
During work, apply load toward supercharging in locking control chamber 9 by locking control port 10, promote tightening sleeve 6 to unclamp
Butterfly spring 5 is compressed while tapered sleeve 7, retaining mechanism is in releasing orientation, treats that piston rod 2 moves to specified location, is stopped
It is pressurized toward locking control chamber 9, discharges the payload of butterfly spring 5, promote tightening sleeve 6 to tighten up tapered sleeve 7, is held tapered sleeve 7 tightly and live
Stopper rod 2, until the position of final lock piston bar 2.
Above example simply elaborates general principle and characteristic of the present utility model, and the utility model is not by above-mentioned example
Limitation, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change and change, these changes
Change and change and both fall within claimed the scope of the utility model.The utility model requires protection scope will by appended right
Ask book and its equivalent thereof.
