Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining The utility model, it is not used to limit the utility model.

As shown in Figure 2 and Figure 3, the present embodiment provides a kind of high energy buffer unit, including cylinder 3, sebific duct 4 and at least one Cylinder body, each cylinder body are connected by sebific duct 4 with cylinder 3.Wherein, cylinder body includes hollow body 5 and piston component 6.Hollow Body 5 is fixed on body 9, and one end of hollow body 5 offers damping hole 51, and one end and the cylinder 3 of sebific duct 4 are tightly connected, glue The other end of pipe 4 is tightly connected with damping hole 51, the interior intracavitary of the other end of 6 sealed set hollow body of piston component 5.

Piston component 6 includes piston 62, piston rod 64, bumper post 61 corresponding with damping hole 51 and sealing ring, bumper post 61 are formed in one or are threadedly coupled with piston rod 64.Piston 62 is socketed on one end of piston rod 64, and sealing ring is wrapped in piston 62 outer peripheral face, the outer surface of piston 62 is set to be in close contact by the inner surface of sealing ring and hollow body 5.Bumper post 61 is fixed In the side in the relative damping hole 51 of piston 62.

In the present embodiment, in order to further function as the effect of buffering, the end face of bumper post 61 is in needle-like.And in order that living Stopper rod 64 moves back and forth in the inner chamber cathetus of hollow body 5, is fixedly provided with the one end relative with damping hole 51 of hollow body 5 Guiding cap 63, the other end of piston rod 64 are arranged in guiding cap 63.

In the present embodiment, the buffer unit is applied in hydraulic cylinder, and cylinder 3 is oily cylinder, and on hollow body 5 also It is provided with steam vent.During start-up operation, hydraulic oil is injected in cylinder 3, hydraulic oil is in air pressure or piston or the work of other pressure Under, along sebific duct 4 enter hollow body 5, and continue to press on bumper post 61, piston 62 is moved out to stop, can now lead to The steam vent crossed on hollow body 5 is exhausted, and prevents from remaining gas in sebific duct 4, hollow body 5 and influenceing buffering effect Fruit.When the moving component 7 on body 9 hits piston rod 64 along guide rail 8 imposes certain pressure to piston rod 64, piston rod 64 Into hollow body 5, so as to promote piston 62 and bumper post 61 inwardly to move, compression hydraulic oil is formed by damping hole 51 for motion Buffering, high energy hydraulic oil are absorbed by the damping action of sebific duct 4, enabled amount, decline the movement velocity of moving component 7. After the speed of moving component 7 declines, the needle-like end face of bumper post 61 continues to move in damping hole 51, continues to play needle-like buffering The effect of device.If the buffer unit is applied in cylinder, its realize the principle of buffering with applied to similar in hydraulic cylinder, It is to be exhausted, is not repeated herein.

It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should It is defined by scope of the claims.
