Preferably, the surface of second oil sealing is provided with duct, and the quantity in duct is four to nine.
Preferably, the surface of the second piston is provided with stopple, and the lower end of stopple is that cylindrical shape upper end is cone-shaped Shape, and the inside clamping stopple in the duct.
Preferably, second oil sealing is located at the lower section of the first oil sealing.
Preferably, the inner surface of the outer surface of the oil storage cylinder and lower protection cylinder is equipped with ball grooves, the ball The inside of clamping ball grooves, and ball grooves are parallel to each other with motion bar.
Compared with prior art, the beneficial effects of the utility model are:The damper is reduced by ball and ball grooves Friction between protection cylinder and lower protection cylinder, prevents from protecting and occur between cylinder and lower protection cylinder abrasion protection effect to reduce;It is logical Crossing second spring increases the damping action of damper;The slow of damper is increased by the second oil sealing, second piston and the first spring Effect is rushed, the excessive damage damper of shock range is prevented, extends the service life of damper.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model;
Fig. 2 is the second oil sealing top view of the present utility model.
It is numbered in figure:It is 1 oil storage cylinder, 2 working cylinders, 3 first pistons, 4 motion bars, 5 rebound valves, 6 flowing valves, 7 first oily Envelope, 8 retraction valves, 9 recuperation valves, 10 second oil sealings, 11 second pistons, 12 first springs, 13 times protection cylinders, protect on 14 cylinder, 15 Ball, 16 second springs.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only to explain The utility model, is not used to limit the utility model.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme:A kind of damper, including oil storage cylinder 1, oil storage cylinder 1 Upper end inwall be fixedly connected working cylinder 2, the inside of working cylinder 2 is provided with first piston 3, and the upper surface middle part of first piston 3 is consolidated Surely motion bar 4 is connected, the surface of first piston 3 is provided with rebound valve 5 and flowing valve 6, and the lower end of working cylinder 2 is provided with the first oil sealing 7, The surface of the first oil sealing 7 is provided with retraction valve 8 and recuperation valve 9, and the inside of oil storage cylinder 1 is provided with the second oil sealing 10 and the second work appearance plug 11, the second oil sealing 10 is located at the lower section of the first oil sealing 7, and the surface of the second oil sealing 10 is provided with duct, and the quantity in duct is four to nine Individual, the excessive buffering effect of hydraulic pressure that the quantity in duct has lacked needs is not good, and the quantity in duct is excessive, then cannot play the work of buffering Stopple is provided with the surface of, second piston 11, it is cone shape that the lower end of stopple is cylindrical shape upper end, cone shape can be with Certain damping action, and the inside clamping stopple in duct are played to hydraulic oil, the lower surface of second piston 11 is fixedly connected One spring 12, the lower end outer surface of oil storage cylinder 1 is fixedly connected lower protection cylinder 13, and the upper end of motion bar 4 is fixedly connected protection cylinder 14, the lower end inner wall and outer wall of upper protection cylinder 14 are equipped with ball 15, and the upper end inwall of upper protection cylinder 14 is fixedly connected the second bullet Spring 16, second spring 16 can increase the damping action of damper, and the lower end of second spring 16 is fixedly connected oil storage cylinder 1, oil storage The inner surface of the outer surface of cylinder 1 and lower protection cylinder 13 is equipped with ball grooves, the inside of the clamping ball grooves of ball 15, ball 15 Along ball grooves movement, the friction of equipment room is reduced, and ball grooves are parallel to each other with motion bar 4.
