For example, sealing ring 6 can be between the first flange 51 and the second flange 52, and 501 bottom of annular groove is equipped with back
Oil groove 502, sealing ring 6 can fit in the bottom of annular groove 501, and the thickness of sealing ring 6 is less than the length of oil-recovery tank 502, from
Without completely obscured oil-recovery tank 502, sealing ring 6 is maked somebody a mere figurehead in the position of oil-recovery tank 502.Sealing ring 6 can move back and forth vertically, when
When sealing ring 6 is moved to against the second flange 52, the oil groove 504 of crossing on the second flange 52 can be blocked, that is, second is led to
Close in road.When sealing ring 6 is moved to against the first flange 51, it can will cross oil groove 504 and open, that is, second channel is beaten
Open, at this time, damping fluid in the second cavity 122 can enter annular groove 501 by crossing oil groove 504, and through oil-recovery tank 502 from oil return
Hole 503 enters the first cavity 121.
Alternatively, sealing ring 6 can be between the first flange 51 and the second flange 52,501 bottom of annular groove is smooth circle
Cylinder.6 inner edge of sealing ring and the distance of 501 bottom of annular groove are more than oil return hole 503 and the minimum range of 501 bottom of annular groove,
So that sealing ring 6 will not block oil return hole 503 completely, the first cavity 121 is connected by oil return hole 503 and annular groove 501 all the time
It is logical.Sealing ring 6 can move back and forth vertically, can be by the second flange 52 when sealing ring 6 is moved to against the second flange 52
Cross oil groove 504 to block, that is, second channel is closed.When sealing ring 6 is moved to against the first flange 51, oil groove can will be crossed
504 open, that is, second channel is opened, but expose oil return hole 503, and at this time, the damping fluid in the second cavity 122 can pass through
Cross oil groove 504 and enter annular groove 501, and enter the first cavity 121 from oil return hole 503.
As depicted in figs. 1 and 2, the buffer of this example embodiment can also include flexible collar 9, the flexible collar 9
Can be the structures such as annular, U-shaped, it can be connected in outside the extension 43 of resilient sleeve 4, so that resilient sleeve 4 and piston shaft 2 be sealed
The position of cooperation clamps.
As depicted in figs. 1 and 2, the buffer of this example embodiment further includes cap assembly 10 and elastic component 11, wherein：
Cap assembly 10 can include block 101 and baffle ring 102, and block 101 can be equipped with axis hole, can be arranged block 101
It is located at one end outside outer barrel 1 in piston shaft 2 and is fixed by a clip, so as to expands the contact of piston shaft 2 by block 101
Face.Block 101 can be located in spill area close to the side of outer barrel 1 formed with spill area, piston shaft 2.Baffle ring 102 can be sheathed on work
Axis 2 is filled in, and the shape and size of baffle ring 102 can be matched with spill area, so as to be sticked in spill area, with from internal Supporting cover
Cap 101, prevents block 101 from deforming.Certainly, cap assembly 10 can also be other structures such as slab construction.
Elastic component 11 can be spring, which can be sheathed on outside piston shaft 2, and one end of spring can be resisted against closure
Part 3, the other end can stretch into the spill area of block 101 and against baffle rings 102.So that by spring clamping in closeouts 3 and block group
Between part 10.Meanwhile spring can be made to be in compressive state all the time, the power away from outer barrel 1 is continuously applied to cap assembly 10, so as to
After disappearing to the pressure of piston shaft 2, reset piston shaft 2.Certainly, in the other examples embodiment of the disclosure, elasticity
Part 11, which can also be that rubber sleeve etc. is other, has component, will not enumerate herein.
The buffer of this example embodiment can also include filling member (not shown), and the shape of the filling member can be with
It is spherical, needle-shaped or other shapes, will not enumerate herein.Filling member can be arranged in damping hole 506, i.e., in damp channel,
And there is the gap flowed through for damping fluid between the inner wall of damping hole 506, can in the case where ensureing that damping hole 506 is unimpeded
Strengthen damping.Meanwhile filling member can be movable in damping hole 506, foregoing the first gasket 7 and the second gasket 8 can stop
Filling member is skidded off from damping hole 506.When needing to take out filling member, the first gasket 7 can be dismantled, then by filling member from damping
Poured out in hole 506.
The operation principle of the buffer of disclosure example embodiment is as follows：
When cap assembly 10 is impacted, piston shaft 2 can be made to be pressed towards in outer barrel 1, the first chamber is extruded with band piston 5
Damping fluid in body 121；Damping fluid in first cavity 121 can enter ring after being pressurized by oil return hole 503 (i.e. first passage)
Shape groove 501, and sealing ring 6 is depressed into the second flange 52 of fitting, to block oil groove 504 (i.e. second channel)；Damping fluid can not
Enter the second cavity 122 by crossing oil groove 504, and the second cavity 122 can be entered by damping hole 506 (i.e. damp channel) so that
Piston 5 and piston shaft 2 are gradually moved to the blind end of outer barrel 1, are gradually reduced the first cavity 121, and the second cavity 122 gradually increases
Greatly.Meanwhile the volume that piston shaft 2 enters in oil pocket 12 gradually increases, after the damping fluid in oil pocket 12 is pressurized, resilient sleeve can extrude
4 indents, reduce air cavity 13, so as to ensure that piston shaft 2 can be moved smoothly into outer barrel 1.In addition, in piston shaft 2 into outer barrel 1
In mobile process, 10 compressible elastomeric part 11 of cap assembly.
When impacting disappearance, elastic component 11 can move backward piston shaft 2 by cap assembly 10, the extruding of piston 5 second
Damping fluid in cavity 122, the damping fluid in the second cavity 122 can enter oil groove 504 and push up sealing ring 6 to the first flange
51, immediately into annular groove 501, so that the first cavity 121 is back to, and without only realizing damping fluid by damping hole 506
Circulation, so that the Rapid reset of piston shaft 2 can be realized.
The buffer of disclosure example embodiment, when being pressurized, passes through caused by damp channel using damping fluid
Buffering is realized in damping, is avoided using spring as bolster, for existing buffer, can be prolonged the service life,
And larger pressure can be born, avoid using larger-size spring to bear high pressure, thus be conducive to reduce overall dimensions and
Weight.When resetting, the reflux of damping fluid can be realized by second channel, annular groove and first passage, and no longer only pass through resistance
Buddhist nun's passage realizes the circulation of damping fluid, can reduce the active force needed for resetting, be easy to implement Rapid reset.
Those skilled in the art will readily occur to the disclosure its after considering specification and putting into practice invention disclosed herein
Its embodiment.This application is intended to cover any variations, uses, or adaptations of the disclosure, these modifications, purposes or
Person's adaptive change follows the general principle of the disclosure and including the undocumented common knowledge in the art of the disclosure
