Specific embodiment
As shown in Figures 1 to 3, a kind of piston structure for being applied to antivibrator described in the utility model, including piston only
1, the piston only 1 is cylindrical-shaped structure, and at the two ends of piston only 1 first end face 11 and second end face are form respectively
12, blind hole 13 is offered in the first end face 11, offer by the side of blind hole 13 from first end face 11 and be through to the second end
The straight channel 14 in face 12, the straight channel 14 is connected with blind hole 13 and connected, and is further opened with arc in the first end face 11 and is led
Chute 15, one end of the arc guiding gutter 15 is connected with straight channel 14, and on the circumferential surface of the piston only 1 ring is offered
Shape embedding slot 16, further equally offers on the circumferential surface of piston only 1 and some is through to annular setting-in from first end face 11
Groove 16 crosses oil groove 17, is further opened with drainage trough 18 in the first end face 11, the two ends of the drainage trough 18 respectively with arc
The other end of guiding gutter 15, one of oil groove 17 of crossing are connected, and the bottom land of annular embedding slot 16 equably offers some
Liquid bath 19 is crossed, each liquid bath 19 of crossing is opened up along the axial direction of piston only 1, and makes the two ends of liquid bath 19 extend respectively to ring
On the both sides cell wall of shape embedding slot 16, some mistakes for being through to annular embedding slot 16 are equably offered in the second end face 12
Oilhole 20.
Piston structure described in the utility model is applied on antivibrator.Wherein, as shown in Figures 4 to 6, antivibrator
General also to include cylinder body 2, piston rod 3, end cover 4, spoiler 5, Y-shaped ring 6, spring base 7, spring 8, the spoiler 5 is
The laminated structure of circular arc, the diameter of the spoiler 5 is less than the diameter of piston only 1, the annular embedding slot of the piston only 1
Being embedded with 16 can be along sealing ring 9 in axial sliding of piston only 1, and the spoiler 5 is fixed on the with piston only 1
On end face 11, and masking sealing function is formed to arc guiding gutter 15, the piston only 1 is arranged on the inner cavity chamber of cylinder body 2
In, the one end of the piston rod 3 is inserted in the blind hole 13 of piston only 1, and the other end of piston rod 3 is drawn from the opening of cylinder body 2
Go out, the Y-shaped ring 6, spring base 7 are sleeved on successively on the piston rod 3 in the inner chamber room of cylinder body 2 with spring 8, the sealing
The lid of end cap 4 is put on the opening of cylinder body 2, and makes the two ends of spring 8 distinguish inner surface and spring base 7 of the overhead in end cover 4
On, interior airtight chamber 10 is formed between the second end face 12 of piston only 1 and the inner cavity chamber bottom of cylinder body 2, in piston sheet
Outer airtight chamber 30 is formed between the first end face 11 and Y-shaped ring 6 of body 1.In interior airtight chamber 10 with outer airtight chamber 30
Hydraulic oil can typically be added.Wherein, in order to limit the moving range of Y-shaped ring 6 and spring base 7, can be in inner cavity chamber's cavity wall of cylinder body 2
On open up out for Y-shaped ring 6 and the activity setting-in limited ring groove of spring base 7.On piston only 1, by arc guiding gutter 15 with it is excessively oily
Groove 17 is connected by drainage trough 18, and arc guiding gutter 15 can be made to realize connecting with outer airtight chamber 30, can also avoid spoiler 5
Extension sprays to constitute from arc guiding gutter 15 and affects on hydraulic oil, makes the ejection of hydraulic oil more smoothly, can make piston only 1
Produce more stable damping.And straight channel 14 is connected with blind hole 13 and connect, the structure of piston only 1 can be made more
It is compact, antivibrator can be made it is more compact, to widen the scope of application of antivibrator；Meanwhile, such setting can also reduce piston
Withdrawing pattern difficulty in the production process of body 1.
When firmly press-in piston rod 3, the inside side shifting of airtight chamber 10 1 of piston only 1, in sealing ring 9 and cylinder body 2
Wall mutually rubs so that sealing ring 9 is close on the cell wall of annular embedding slot 16 near first end face 11, and at this moment, sealing ring 9 is by shape
The sealing process of oil groove 17 is crossed in pairs.Meanwhile, hydraulic oil can be entered into through straight channel 14, arc guiding gutter 15, drainage trough 18
In outer airtight chamber 30.I.e. straight channel 14, arc guiding gutter 15, drainage trough 18 together constitute damping flow channel.Due to hydraulic oil
When entering in arc guiding gutter 15 from straight channel 14, can be subject to stopping for spoiler 5, make hydraulic oil lentamente from interior closed chamber
Room 10 is entered in outer airtight chamber 30, so as to form buffering effect.Wherein, the straight channel 14 of piston only 1 and arc water conservancy diversion
Relative other components of groove 15 are independent, will not be affected by other components, will not especially be subject to the shadow of the deformation of sealing ring 9
Ring, damping is sufficiently stable.In use, applied external force is bigger, and hydraulic oil is subject to the resistance of spoiler 5 to get over
Greatly, so as to producing very good damping, it is to avoid the generation of shock, the service life of antivibrator can effectively be extended.
When piston rod 3 is pulled out, the outside side shifting of airtight chamber 30 1 of piston only 1, in sealing ring 9 and cylinder body 2
Wall mutually rubs so that at this moment sealing ring 9 is crossed oil groove 17 and opened away from the cell wall of annular embedding slot 16 near first end face 11, liquid
Force feed was passed through oil groove 17, annular embedding slot 16, liquid bath 19, oil-through hole 20 excessively and entered into interior airtight chamber from outer airtight chamber 30
In 10.Cross oil groove 17, annular embedding slot 16, liquid bath 19, oil-through hole 20 excessively and together constitute drainback passage.Due to excessively oily
Without any block piece on groove 17, excessively liquid bath 19, oil-through hole 20, and cross oil groove 17, cross each groove in liquid bath 19, oil-through hole 20
The quantity of pore structure all offers multiple, can accelerate the flowing of hydraulic oil, meanwhile, it is each to cross oil groove 17, cross liquid bath 19, oil-through hole
20 are uniformly laid on piston only 1, can guarantee that the stress at each position of piston only 1 is identical, move piston only 1
It is more steady.The piston only 1 has the advantages that oil return is rapid steadily, is not in vibrating noise.
