Description
Technical field
The utility model is related to a kind of ventilative bearing, more particularly to a kind of air-leg ventilative bearing.
Background technology
Lifting air pressure rod is used widely in daily life at present, and that is especially applied in office furniture is more wide
It is general, it is the main composition part of office revolving chair, the ventilative bearing used in air pressure rod is lifted in the prior art, steering capability is poor,
And be easily broken in test process, the problems such as insufficient strength, cause the complaint of client to raise, cause quality cost to increase.
Utility model content
The utility model aims to solve the problem that drawbacks described above, there is provided a kind of ventilative bearing of air-leg.
In order to overcome defect present in background technology, the utility model solves the technical scheme that its technical problem is used
It is：The ventilative bearing of this air-leg includes inner tube support level, piston rod supporting surface, air-vent, ventilating groove, pilot hole and adds
Strong muscle, inner tube support level and piston rod supporting surface composition stairstepping and be internally formed cavity, piston rod supporting surface as
On inner tube support level, ventilating groove is provided with the junction of inner tube support level and piston rod supporting surface, is provided with ventilating groove
Air-vent, the centre of the piston rod supporting surface is provided with pilot hole.
According to another embodiment of the present utility model, further include the ventilating groove and air-vent all at least provided with three
It is individual.
According to another embodiment of the present utility model, said inner tube support level and piston rod supporting surface are further included
Reinforcement is provided with the cavity of formation.
The beneficial effects of the utility model are：The simple structure of the ventilative bearing of this air-leg, overall structure uses POM
Material, is provided with air-vent, ventilating groove, with guidance quality it is good, intensity is high the characteristics of.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2 be Figure 1A-A to structural representation；
Fig. 3 is the upward view of relative Fig. 1；
Wherein：1 inner tube support level, 2, piston rod supporting surface, 3, air-vent, 4, ventilating groove, 5, pilot hole, 6, strengthen
Muscle.
Specific embodiment
Fig. 1 is structural representation of the present utility model, and figure includes inner tube support level 1, piston rod supporting surface 2, breathes freely
Hole 3, ventilating groove 4, pilot hole 5 and reinforcement 6, inner tube support level 1 and the composition stairstepping and interior of piston rod supporting surface 2
Portion forms cavity, piston rod supporting surface 2 as on inner tube support level 1, in inner tube support level 1 and piston rod supporting surface 2
Junction is provided with ventilating groove 4, air-vent 3 is provided with ventilating groove 4, as shown in Fig. 2 the centre of piston rod supporting surface 2 is provided with and leads
To hole 5.Ventilating groove 4 and air-vent 3 are all at least provided with three.As shown in figure 3, inner tube support level 1 and the shape of piston rod supporting surface 2
Into cavity in be provided with reinforcement 6.
Inner tube support level 1 and piston rod supporting surface 2 constitute stairstepping and are internally formed cavity, are provided with cavity
Reinforcement 6, reinforcement 6 can improve integrally-built intensity, not only play ventilative by setting air-vent 3 and ventilating groove 4
Effect, and can be with material-saving.
The simple structure of the ventilative bearing of this air-leg, overall structure uses POM materials, is provided with air-vent, breathes freely
Groove, with guidance quality it is good, intensity is high the characteristics of.
