The cross-sectional area of stopper rod realizes the movement of piston rod less than the cross-sectional area of piston to the pressure difference generated.Due to air-leg
Be widely used, the requirement to the pressure-bearing tolerance of air-leg is also higher and higher.The pressure cylinder of existing air-leg is usually using carbon
Steel pipe is processed as raw material, and usual wall thickness is thin, and bearing capacity is insufficient, causes series mass problem or service life not up to standard.
Utility model content
In order to overcome the shortcomings of existing air-leg pressure-bearing, the utility model provides a kind of high pressure-bearing air-leg.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of high pressure-bearing air-leg, includes pressure
Cylinder, the pressure cylinder both ends are sealed by sealing element one and sealing element two, and pressure cylinder internal slide is connected with piston rod, described
Tubulose foam pad is arranged between pressure cylinder outer wall, sealing element one and sealing element two, the foam pad outer cover is equipped with pressure-bearing set
Pipe.
Another embodiment according to the present utility model further comprises that the pressure-bearing casing profile is in the arcuation of evagination
Structure, the intensity that the arc structure of evagination is conducive to absorption pressure, increases pressure-bearing casing, while avoiding space is formed in inside,
Provide better protection against internal pressure cylinder.
Another embodiment according to the present utility model further comprises that the pressure-bearing casing material is C20, and intensity is good,
Bearing capacity is strong.
Another embodiment according to the present utility model further comprises, also includes air bag component, and the air bag component is set
It is bolted to connection between foam pad and pressure-bearing casing, and with pressure-bearing internal surface of sleeve pipe, the air bag component is in pressure-bearing set
When pipe is collided, it can be excited and generate gas, to play the role of excellent protecting against shock.
Another embodiment according to the present utility model further comprises that the air bag component includes sensor, inflation system
System and air bag, the sensor are connected with inflation system, and the inflation system gas outlet is connected with air bag, more efficiently prevents from pressure
Power cylinder compressive deformation.
The utility model has the beneficial effects that external pressure can effectively be born by setting pressure-bearing casing and foam pad,
Compensator or trimmer pressure cylinder compression situation, prevents pressure cylinder from deforming, and completely cuts off the influence of external high temperature and low temperature to pressure cylinder, passes through setting
Air bag component can excite when pressure-bearing casing is collided and generate gas, form buffer layer, play preferably protecting against shock
Effect, to guarantee the precision of pressure cylinder, extends the service life of air-leg.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
1, pressure cylinder in figure, 2, sealing element one, 3, sealing element two, 4, piston rod, 5, foam pad, 6, pressure-bearing casing, 7, gas
Capsule component, 8, sensor, 9, inflation system, 10, air bag.
Specific embodiment
If Fig. 1 is the structural schematic diagram of the utility model, a kind of high pressure-bearing air-leg includes pressure cylinder 1, the pressure cylinder
1 both ends are sealed by sealing element 1 and sealing element 23, and 1 internal slide of pressure cylinder is connected with piston rod 4, in the pressure cylinder 1
Tubulose foam pad 5 is arranged between outer wall, sealing element 1 and sealing element 23,5 outer cover of foam pad is equipped with pressure-bearing casing
6。
The specific working principle is as follows: the pressure-bearing set when air-leg is by external immense pressure, outside pressure cylinder 1
Most pressure can be absorbed in pipe 6, and the foam pad 5 inside pressure-bearing casing 6 can play the role of flexible buffer, further
Prevent pressure cylinder 1 by huge collision, to prevent 1 compressive deformation of pressure cylinder, furthermore it is external can also to play isolation for foam pad 5
The effect of environment temperature prevents pressure cylinder 1 from being influenced by high temperature or low temperature, to guarantee the accurate reliable of air-leg movement.
Another embodiment according to the present utility model further comprises that 6 section of pressure-bearing casing is in the arcuation of evagination
Structure, the intensity that the arc structure of evagination is conducive to absorption pressure, increases pressure-bearing casing 6, while avoiding space is formed in inside,
Provide better protection against internal pressure cylinder 1.
Another embodiment according to the present utility model further comprises that 6 material of pressure-bearing casing is C20, than common
The intensity of medium carbon steel is good, and bearing capacity is strong.
Another embodiment according to the present utility model further comprises, also comprising air bag component 7, the air bag component 7
It is located between foam pad 5 and pressure-bearing casing 6, and is bolted to connection with 6 inner wall of pressure-bearing casing, the air bag component 7 exists
