Sectional dimension is more than the sectional dimension of bumper post, and accepting groove connects with oil drain out.
Preferably, piston rod is provided with baffle plate away from one end of piston, and cylinder cap is provided with gripper shoe, baffle plate with
The spacing of gripper shoe is not more than the spacing of piston and cylinder bottom.
Preferably, gripper shoe is made up of elastomeric material.
Preferably, multiple oil-ins are uniformly distributed centered by the centrage of piston.
Preferably, the stepped setting of oil-in, from inside to outside, the size of oil-in is gradually reduced.
Preferably, the peripheral side of piston is provided with multiple grade groove.
Preferably, multiple grooves are uniformly distributed.
Preferably, groove is pit or groove.
Preferably, the bottom of cylinder bottom is provided with alignment pin.
In this utility model, when piston rod shrinks, bumper post gradually extrudes the hydraulic oil in accepting groove, houses
Oil pressure in groove increases, and also can react on piston, reduces the translational speed of piston, it is to avoid piston impact cylinder
The end, it is to avoid vibrations；Oil drain out becomes horn-like setting, when carrying out oil extraction, hydraulic oil through oil drain out,
Speed is the most slack-off, reduces oil extraction speed, this makes it possible to ensure that piston rod slowly shrinks, reduces piston rod
Contraction speed, it is to avoid unexpected occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation in an embodiment after piston amplification；
Fig. 3 is the structural representation in another embodiment after piston amplification.
Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment
Combination that can be mutual；Below with reference to the accompanying drawings and in conjunction with the embodiments to this utility model elaborate.
With reference to Fig. 1-3:
The one that the utility model proposes hoists cylinder, including cylinder cap 1, cylinder barrel 2, cylinder bottom 14, piston 3, lives
Stopper rod 4, fairlead 5, piston 3, fairlead 5 be placed in cylinder barrel 2, piston 3 and cylinder barrel 2, cylinder bottom 14
Between form rodless cavity 6, one end of piston rod 4 is connected with piston 3 through fairlead 5, and cylinder barrel 2 is provided with
Multiple oil-ins 7, oil drain out 8, above-mentioned oil-in 7 connects with rodless cavity 6, and oil drain out 8 becomes horn-like and sets
Putting, from inside to outside, the size of oil drain out 8 is gradually increased, and piston 3 is provided with buffering near the side of cylinder bottom 14
Post 9, cylinder bottom 14 is provided with the accepting groove 10 for housing bumper post 9, accepting groove 10 near the side of piston 3
Sectional dimension more than the sectional dimension of bumper post 9, accepting groove 10 connects with oil drain out 8；Piston rod 4 is received
During contracting, bumper post 9 gradually extrudes the hydraulic oil in accepting groove 10, and the oil pressure in accepting groove 10 increases, also
Piston can be reacted on, reduce the translational speed of piston, it is to avoid piston impact cylinder bottom, it is to avoid vibrations；Oil extraction
8 one-tenth horn-like settings of mouth, when carrying out oil extraction, hydraulic oil is when oil drain out 8, and speed is the most slack-off,
Reduce oil extraction speed, this makes it possible to ensure that piston rod slowly shrinks, reduce the contraction speed of piston rod, keep away
Exempt from unexpected generation.
Further, piston rod 4 is provided with baffle plate 11 away from one end of piston, and cylinder cap 1 is provided with gripper shoe
12, the spacing of baffle plate 11 and gripper shoe 12 is not more than the spacing of piston and cylinder bottom, slightly smaller than, so
Avoid reducing the stroke of piston rod, it is also possible to avoid piston to collide with cylinder bottom；Live when piston contacts with cylinder bottom
Before contact, baffle plate 11 contacts with gripper shoe 12, increases baffle plate 11, gripper shoe 12, it is to avoid piston and cylinder
The end, collides.
Further, gripper shoe 12 is made up of elastomeric material；Further reduce the contraction speed of piston.
Multiple oil-ins 7 are uniformly distributed centered by the centrage of piston；Hydraulic oil enters from multiple oil-ins 7
Entering in cylinder barrel 2, hydraulic oil is uniform to the impulsive force of piston, it is to avoid piston unbalance stress, effectively avoids living
Stopper rod 4 tilts, shakes, it is ensured that support effect.
The stepped setting of oil-in 7, from inside to outside, the size of oil-in 7 is gradually reduced；Hydraulic oil warp
Crossing oil-in 7 when entering cylinder barrel 2, the area of oil-in 7 increases, and hydraulic oil oil prompt drop is low, and then reduces
Impact to piston, it is to avoid rock, it is ensured that support effect.
Further, the peripheral side of piston is provided with multiple grade groove；Owing to using for a long time,
The foreign material such as abrasive dust can be produced between the sidewall of piston and cylinder barrel 2, multiple millimetre-sized by arranging on piston
Groove, grade groove can be as micro-storage pool of hydraulic oil or the nail collection slot of abrasive dust, for piston and cylinder barrel 2
Contact between sidewall provides lubrication or provides lubrication for the firm friction surface started, and accommodates because of boundary lubrication
Or the abrasive dust that dry friction produces, thus reduce abrasion, increase the service life.
Further, multiple grooves are uniformly distributed, and improve using effect.
In one embodiment, groove is groove 1501.
In another embodiment, groove is pit 1502.
Further, the bottom of cylinder bottom 14 is provided with alignment pin 13；Conveniently position with the external world, improve and use
Effect.
The above, only this utility model preferably detailed description of the invention, but protection model of the present utility model
Enclose and be not limited thereto, the technology model that any those familiar with the art discloses at this utility model
