Abstract
The utility model discloses a gas and oil mixing damper. The gas and oil mixing damper comprises a tube body; hydraulic oil is filled in the tube body; a piston and a piston rod are arranged in the tube body; one end of the piston rod is connected with the piston, and the other end of the piston rod is extended out of the tube body; the rear end of the piston has a structure of a bevel groove; the front and rear end faces of the piston are provided with flow holes; and O-shaped rings are arranged in bevel grooves at the rear end of the piston. The gas and oil mixing damper can exert the damping function when used, can be easily returned and is convenient to operate.
Description
Technical field
The utility model relates to a kind of damper, specifically a kind of oil gas mixing damper.
Background technique
At present existing damped products is various informative, but all be single be purpose with the damping, can not realize self-return, thereby in use need in addition additional other returning devices, just can play using effect.
Summary of the invention
In order to overcome the problem that existing technology exists, the purpose of the utility model provides a kind of oil gas mixing damper, and this damper in use can play damping function, and light return is easy to operate again.
The purpose of the utility model realizes through following technological scheme:
A kind of oil gas mixing damper comprises body, in body, is provided with hydraulic oil, it is characterized in that: in body, be provided with piston and piston rod, an end of piston rod is connected with piston, and the other end reaches outside the body; Said piston rear end is an oblique angle groove structure, on the front/rear end of piston, is equipped with metering orifice, in the oblique angle of piston rear end groove, is provided with O shape circle.
In the utility model, the oblique angle of piston bottom end can be 45 degree.The metering orifice aperture of piston rear end is greater than the metering orifice aperture of piston nose.
The utility model is connected piston with piston rod, the piston kerve is 45 degree oblique angles, and piston end face is four metering orifices; Front-end face is a less metering orifice; When stressed inside compression, O shape circle moves up according to movement locus, with the upper end and the inner tube wall closure at piston rear end oblique angle; To overflow from the less metering orifice of piston nose when fuel-displaced like this, produce damping.Otherwise; When to internal resistance less than pipe during internal pressure, piston and piston rod make O shape enclose the front-end face that moves to piston reversing motion; At this moment the other end that will spill into piston from four metering orifices and the less metering orifice of tube wall through end face of the hydraulic oil in the pipe makes its return.In use reciprocal, produce damping, return one effect.
Compared with prior art, the utility model in use can play damping function, and light return is easy to operate again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The described oil gas mixing of a kind of the utility model damper comprises body 1, in body, is provided with hydraulic oil 11, in body 1, is provided with piston 2 and piston rod 3, and an end of piston rod 3 is connected with piston 2, and the other end reaches outside the body 1; Piston 2 bottoms are 45 degree oblique angle groove structures, on the front/rear end of piston 2, are equipped with metering orifice, and the metering orifice aperture of piston rear end is greater than the metering orifice aperture of piston nose.In the oblique angle groove of piston 2 rear ends, be provided with O shape circle 4.
During use, the piston nose face is a less metering orifice, when stressed inside compression; O shape circle moves up according to movement locus; Closed with the upper end and the inboard wall of tube body at piston rear end oblique angle, will overflow from the less metering orifice of piston nose when fuel-displaced like this, produce damping.Otherwise; When to internal resistance less than pipe during internal pressure, piston and piston rod make O shape enclose the front-end face that moves to piston reversing motion; At this moment the other end that will spill into piston from four metering orifices and the less metering orifice of tube wall through end face of the hydraulic oil in the pipe makes its return.In use reciprocal, produce damping, return one effect.
The utility model in use can play damping function, and light return is easy to operate again.
