Description
Technical field
The present invention relates to double-acting buffer technical field, particularly relate to simple exquisite, the saving material of a kind of design
Material, the double-acting buffer increased the service life.
Background technology
Buffering closes door everywhere it can be seen that such as warehouse, freezer door are buffering closes door.Ice at present
Case does not the most find pooling feature, and general inside refrigerator door all can place castor, if refrigerator doors band
If having buffering to close, then performance is more preferable；And buffer closedown door and can also prevent from door from producing shutting when hitting
Hitting, optimal situation is door can be allowed quickly to shut and do not clash into.
The life problems of product, the life of product of prior art is many at 2 ten thousand to 10 ten thousand times, and uses bilayer
Sleeve structure, volume is big, and cost is high.
Therefore, need badly and a kind of design simple exquisiteness, save material, the double-acting buffer that increases the service life.
Summary of the invention
It is an object of the invention to provide and a kind of design simple exquisiteness, save material, the double cropping that increases the service life
Use buffer.
To achieve these goals, the technical scheme that the present invention provides is: provide a kind of double-acting buffer,
It include hollow sleeve and with sleeve with the use of push rod, sleeve inner be provided with guide support,
One piston component, the second piston component, sleeve is provided with the passage that tube expansion is formed, and one end of push rod is through guiding
Support member is fixing with first piston assembly to be connected, and forms the first compression between first piston assembly and sleeve head
Space, forms the end of the second compression stroke, the second piston component and sleeve between first and second piston component
It is compressed gas in forming the 3rd compression stroke, the 3rd compression stroke between portion, for keeping stability with inertia
Gas is preferred.First compression stroke and the second compression stroke content are hydraulic damping oil, the second piston component
For using double-Y shaped sealing ring to be arranged symmetrically with, and can slide in sleeve inner, to the second compression stroke and the
Three compression strokes carry out two way seal, and when door is opened by external force, push rod drives first piston assembly to sleeve
Bottom direction motion, now first piston assembly check valve conducting, the second compression stroke hydraulic damping oil
Can the most sensible first compression stroke, make door quickly can open in the case of without additional friction,
Second piston component slightly moves with balance and the change of compensation the second compression stroke to the bottom direction of sleeve, the
Three compression strokes are compressed；When external force removes, under the promotion of slight door closing force, in the 3rd compression stroke
Compressed gas transfer force to first piston assembly by the second piston component and make to close by push rod,
Now the hydraulic damping oil of the first compression stroke is by the most sensible second compression sky of the tube expansion passage on sleeve
Between, door is not because having additional friction to start quick closedown from angle of release 90 degree under pressure, when door is closed
When about 20 degree, tube expansion passage reduces, and flowed friction is gradually increased, and the speed of door is gradually reduced, and reaches both may be used
Quickly to close the door, the effect closed the door can be buffered again.
The two ends of the second piston component are provided with collar or catch, and the y-type seal ring of the second piston component
And it is coated with lubricating oil between sleeve lining, and the injection hydraulic damping of first and second compression stroke is oily, the 3rd
Compression stroke injects compressed gas.
Radially distributed one or several passages, passage includes initial working stage, smooth working stage, transition
Ending phase, passage can have different cross sectional shapes, size, can require to determine according to using vertically
Starting point, end point, to meet different use requirements.
Conflict, separately in the bottom being additionally provided with flexible member, flexible member one end and sleeve in 3rd compression stroke
Conflict with collar or catch in one end.
Being additionally provided with on push rod for turning on the first compression stroke and the passage of the 3rd compression stroke, passage includes
For allowing entrance that hydraulic damping oil enters and for the outlet allowing hydraulic damping oil spray.
Outlet includes the first outlet that relative aperture is bigger and smaller the second outlet and the 3rd of two bores
Exporting, and passage is arranged at inside push rod, the first outlet, the second outlet and the 3rd outlet may be contained within push rod
Outer wall on, the first outlet is arranged on than the second outlet, the 3rd outlet closer to the position of guide support,
When push rod moves to the bottom direction away from sleeve, the first outlet initially enter guide support internal and by
Gradually it is blocked, so that being blocked completely, and when the second outlet, the 3rd outlet entrance guide support inside also
Gradually it is blocked, so that being blocked completely.
Second outlet is identical with the bore of the 3rd outlet.
First outlet, the second outlet and the 3rd outlet are arranged on the outer wall of push rod for radially rehearsal.
Sleeve is positioned at the first compression stroke position, is sequentially provided with initial work along the bottom direction away from sleeve
Section, smooth working section, changeover portion and transition, the external diameter of initial active section is in quickly increasing structure, steadily
The external diameter of active section keeps constant, and the external diameter of changeover portion is in quickly reducing structure, and the external diameter of transition is in slowly
Reduce structure.
Compressed gas is preferred with noble gas, it is also possible to be air.
The present invention also provides for another double-acting buffer, including hollow sleeve and with sleeve with the use of
Push rod, sleeve inner be provided with in being provided with guide support, piston component, sleeve tube expansion formed passage,
One end of push rod is connected through guide support and piston component are fixing, shape between piston component and sleeve head
Become the first compression stroke, between piston component and the bottom of sleeve, form the second compression stroke, the first compression sky
Between with the second compression stroke content be hydraulic damping oil, have spring in the second compression stroke, door is by external force
When opening, push rod drives piston component to move to the bottom direction of sleeve, now the conducting of piston component check valve,
The hydraulic damping oil of the second compression stroke can the most sensible first compression stroke, make the door can be without volume
Quickly opening in the case of external resistance, now spring is compressed, when external force removes, at slight door closing force
Under promotion, spring transfers force to piston component and makes a closedown by push rod.Now first compression stroke
Hydraulic damping oil is by the most sensible second compression stroke of tube expansion passage on sleeve, and door is because the most additionally hindering
Power starts quick closedown, when door closes about 20 degree, tube expansion passage from angle of release 90 degree under pressure
Reducing, flowed friction is gradually increased, and the speed that door is closed is gradually reduced, and reaches both can quickly close the door, again
The effect closed the door can be buffered.
Compared with prior art, owing to, in double-acting buffer of the present invention, sleeve has tube expansion passage, internal
Being provided with guide support, first piston assembly, the second piston component, the second piston component is for using double Y
RunddichtringO is arranged symmetrically with, and can play the effect of two way seal, and can slide in sleeve inner, to first
Compression stroke and the second compression stroke carry out two way seal, utilize compressed gas to promote the design of hydraulic damping oil,
Flexible member can not be utilized, therefore, it is possible to the problem overcoming the flexible member life-span itself.
