Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model；
Fig. 2 is the portion the A enlarged drawing of Fig. 1.
Specific embodiment
As shown in FIG. 1 to FIG. 2, a kind of two-way resistance damper, including oil cylinder ontology 100, piston 200 and piston rod 300,
Piston rod 300 connect with piston 200 and does the movement of piston 200, the oil cylinder ontology in oil cylinder ontology 100 with piston 200
It is equipped with internal airbag 400 in 100, further includes damping mechanism 500, the damping mechanism 500 is fixed at oil cylinder ontology 100
It is interior, the first chamber a for accommodating internal airbag 400, the built-in gas are formed between damping mechanism 500 and oil cylinder ontology 100
Capsule 400 is arranged in first chamber a, and the piston 200 is equipped with the first through hole 210 passed through for damping mechanism 500, the piston
Bar 300 is equipped with the second through-hole 310 passed through for damping mechanism 500, and the first through hole 210 is connected to the second through-hole 310, and the
One through-hole, 210 diameter passes through first through hole 210 and the second through-hole less than 310 diameter of the second through-hole, described 500 one end of damping mechanism
310, second chamber b, piston 200 and piston rod 300 and oil are formed between damping mechanism 500 and piston 200 and oil cylinder ontology 100
Third chamber c is formed between cylinder ontology 100, piston rod 300 is equipped with return port 320, and second chamber b and third chamber c pass through back
Discharge orifice 320, first through hole 210 are connected to the second through-hole 310, and damping mechanism 500 is equipped with outage 530, second chamber b and first
Chamber a is connected to by outage 530, and damping mechanism 500, which is inserted into one end of the second through-hole 310 and the sealing of the second through-hole 310, makes oil
Sealing is formed in cylinder ontology 100, when piston 200 pushes or rises, the resistance between piston 200 and damping mechanism 500 is gradually
Becoming larger, working principle is as follows, and when piston rod 300 is pushed with piston 200, the pressure of second chamber b is become larger, and second
Medium (oil, liquid or gas) in chamber b is pressed into first chamber a by outage 530, the internal airbag in first chamber a
400, which are pressurized, shrinks, while the certain media of second chamber b enters first chamber a by first through hole 210 and the second through-hole 310,
The first through hole 210 and damping adjustable column 520 of piston 200 cooperate, since the diameter of damping adjustable column 520 is the big centre in both ends
It is small, so the first through hole 210 of piston 200 and the damping of damping 520 diameter of adjustable column become larger, to realize piston 200
Bumper and absorbing shock purpose when pushing, when piston 200 is sprung back (when namely piston 200 rises), 400 discharge of internal airbag restores former
Shape, the medium in first chamber a enter second chamber b by outage 530, and first chamber a is pressurized, Jie in first chamber a
Matter enters second chamber b by return port 320, the second through-hole 310 and first through hole 210, the first through hole 210 of piston 200 with
The resistance of damping 520 diameter of adjustable column becomes larger, thus bumper and absorbing shock when realizing rebound.
The damping mechanism 500 includes pedestal 510 and damping adjustable column 520, the pedestal 510 and damping adjustable column 520
It is an integral structure, fixing assembling is sealed between 510 outer wall of pedestal and oil cylinder ontology 100, pedestal 510 will be for that will damp tune
Segmented column 520 is fixed in oil cylinder ontology 100.
The 520 both ends diameter of damping adjustable column is greater than mid diameter, the damping adjustable column 520 taken in this product
The arc-shaped structure in cross section two sides can also use cross section for the diameter change of other shapes, but preferably cross section two sides
Arc-shaped structure.
520 both ends of damping adjustable column to the mid diameter gradually becomes smaller, damping 520 both ends of adjustable column to mid diameter
It gradually becoming smaller, the resistance for making piston 200 when pushing or rising (rebound) between damping adjustable column 520 becomes larger, thus
Play the effect of bumper and absorbing shock.
520 maximum gauge of damping adjustable column is greater than first through hole 210, the insertion of damping adjustable column 520 second
One end position of through-hole 310 remains at 320 top of return port, and damping 520 upper end of adjustable column leads to the second of piston rod 300
Hole 310 remains sealing cooperation, guarantees in oil cylinder ontology 100 always in sealing.
Internal airbag 400 plays the role of ensuring in oil cylinder ontology 100 always not air.
The utility model has the beneficial effects that the utility model provides a kind of two-way resistance damper, this product passes through setting
A piece both ends diameter is big, the small damping adjustable column of mid diameter, is cooperated by the through-hole of damping adjustable column and piston, piston is made to exist
Resistance becomes larger always when pushing or rising, therefore achievees the purpose that two-way resistance, and good damping effect, structure is simple, non-
