Abstract
The utility model relates to a fork truck hydro -cylinder buffer structure. In vehicles such as fork truck, automobile, engineering machine tool, descend when the hydro -cylinder that the part is reciprocal when being close to the stroke terminal carries out direct striking, influence very much the life and the operating efficiency of part. The utility model discloses a cylinder, piston rod, piston, cylinder bottom, being equipped with buffer shaft on its characterized in that cylinder bottom, being equipped with the cushion collar in the piston, it has hole and buffer shaft to match to open in the cushion collar, the outside of cushion collar sets up steel wire retainer ring. The utility model relates to a rationally, convenient assembling is equipped with buffer shaft on the cylinder bottom, be equipped with the cushion collar in the piston, by steel wire retainer ring card jail for the product Assembly degree of difficulty reduces, and it is better to cushion steady effect, has practiced thrift the energy, has improved the efficiency of production, has prolonged spare part life.
Description
Technical field
The utility model is related to a kind of fork truck oil cylinder improved structure, especially a kind of fork truck cylinder buffer structure.
Background technology
In the vehicles such as fork truck, automobile, engineering machinery, back and forth carry out directly when oil cylinder declines part when close to stroke terminal
Connect shock, the very service life of impact part and operational efficiency.
Content of the invention
The utility model is directed to the problem that prior art exists, and provides a kind of fork truck cylinder buffer structure, good buffer effect
And the reliability that operates steadily, improve the operational efficiency of oil cylinder inner part, also reduce accessory loss.
The technical solution adopted in the utility model is: a kind of fork truck cylinder buffer structure, including cylinder barrel, piston rod, piston,
Cylinder bottom, it is characterised in that cylinder bottom is provided with buffer shaft, is provided with cushion collar in piston, have endoporus and buffer shaft phase in cushion collar
Join, the outside setting elastic spring of described cushion collar.Piston reaches in the certain distance before stroke terminal, by oil in oil-discharging cavity
Liquid is closed, and is discharged by the gap between cushion collar and cylinder bottom major axis, so that the fluid being closed, produces certain delaying
Stamping press acts on the oil extraction side of piston, gradually reduces the speed of service of piston and carry an object, thus reaching retarding braking
Purpose.
The bottom of described piston has endoporus, and in the hole is provided with elastic spring groove, and in described elastic spring groove, setting is described
Elastic spring.
The endoporus of described cushion collar is provided with 0.5 ° of taper, and end has cross recess excessively oily.
Setting sealing ring and hole support ring between described piston and cylinder barrel.
The utility model is reasonable in design, easy to assembly, and cylinder bottom is provided with buffer shaft, is provided with cushion collar, by steel wire in piston
Back-up ring card jail is so that Product Assembly difficulty reduces, and stable buffering effect is more preferably, has saved the energy, has improve the effect of production
Rate, extends parts service life.
Brief description
Fig. 1 is the schematic diagram of the utility model structure.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is made to describe into a line:
As shown in figure 1, the utility model includes cylinder barrel 1, piston rod 6, piston 2, cylinder bottom 5, cylinder bottom is provided with buffer shaft,
It is provided with cushion collar 3 in piston, have endoporus in cushion collar 3 and match with buffer shaft.
The bottom of piston has endoporus, and in the hole is provided with elastic spring groove, the described elastic spring of setting in elastic spring groove
4.The endoporus of cushion collar is provided with 0.5 ° of taper, and it is excessively oily that end has cross recess.Setting sealing ring 8 and hole between piston and cylinder barrel
With support ring 7.
The utility model is reasonable in design, easy to assembly, and cylinder bottom is provided with buffer shaft, is provided with cushion collar, by steel wire in piston
Back-up ring card jail is so that Product Assembly difficulty reduces, and stable buffering effect is more preferably, has saved the energy, has improve the efficiency of production.
Listed above is only specific embodiment of the utility model, and the utility model is not limited to above example,
Can also there are many similar structures change designs.Those of ordinary skill in the art can be direct from the utility model disclosure
The all deformation derived or associate, are all considered as protection domain of the present utility model.
