Abstract
The invention relates to the application field of lifter hydraulic oil cylinders. When the lifter hydraulic oil cylinders descend to the low position, buffering descending is performed, so that the impact force and the noise during grounding of the lifter are reduced effectively.
Description
Affiliated technical field
This patent relates to a kind of hydraulic oil cylinder cushion, impact force and noise while declining to reduce lifting machine.
Background technique
Automobile is hydraulic jack with the major impetus performance element of lifting machine lifting.Conventionally, lifting machine will keep certain speed while declining, and when can work as lifting machine decline lowest order or landing, this rate of descent can cause certain impact force, causes lifting machine concuss and makes a noise.
Summary of the invention
The invention provides a kind of damping device that is contained in (Fig. 1) in lifting machine oil hydraulic cylinder, when lifting machine drops to low level, carry out buffer falling, impact force and noise while landing effectively to reduce lifting machine.
Accompanying drawing explanation
Fig. 1 is the cross section view of type patent cylinder apparatus of the present invention.
In figure 1, hydraulic jack cylinder bottom, 2, guide sleeve, 3, spill port, 4, seal ring, 5, Returnning spring, 6, piston, 7, cylinder sleeve, 8, piston rod
A: moving direction
Specific works mode
Working principle: see structural representation (Fig. 1), on guide sleeve (2), be equipped with seal ring (4) and Returnning spring (5), guide sleeve (2) is fixed on the longitudinal center line of piston (6), when piston (6) drops to seal ring (4) contact oil cylinder with lifting machine at the bottom of, when (1), seal ring (4) closes the regular path of hydraulic oil.Now, hydraulic oil can only flow away by another spill port from cylinder bottom (1), and this spill port is the aperture of processing especially in advance, and hydraulic oil plays the effect of throttling when small holes flows back to.Like this, lifting machine just slowly declines, until lifting machine lands completely.Thereby effect ground reduces lifting machine while landing impact force and noise.
Claims (1)
1. a damping device that is contained in (Fig. 1) in lifting machine oil hydraulic cylinder, when lifting machine drops to low level, with seal ring, close the regular path of hydraulic oil, hydraulic oil is flowed back to by another one aperture, play the effect of buffer falling, impact force and noise while landing effectively to reduce lifting machine.
