Abstract
The invention relates to the technical field of pneumatic rods and particularly relates to a plastic plane bearing of a pneumatic rod. The plastic plane bearing of the pneumatic rod comprises a bearing body and a guide hole; the guide hole is located in the center of the bearing body; arcs are arranged around the guide hole in the surface of the bearing body. The plastic plane bearing of the pneumatic rod is made of a POM material, so that the plastic plane bearing has high abrasion resistance; the arcs are designed at two ends of the plane, so that the overall strength is improved while the friction is reduced.
Description
Technical field
The present invention relates to a kind of plane bearing, particularly relate to the plastic surface bearing of a kind of air-leg.
Background technology
Lifting air lever is used widely in daily life at present, and that applies in office furniture especially is the widest
General, it is the main composition part of office revolving chair, the plane bearing used in lifting air lever in prior art, as it is shown in figure 1, existing
Having the bearing used in technology is the PE set form with regard to steel ball, and auxiliary rotates, but the life-span is short, broken, and bearing two ends use
, after assembling finished product, easily there is noise in metallic gasket.
Summary of the invention
Present invention seek to address that drawbacks described above, it is provided that the plastic surface bearing of a kind of air-leg.
In order to overcome defect present in background technology, the technical solution adopted for the present invention to solve the technical problems is:
The plastic surface bearing of this air-leg includes bearing body and pilot hole, and the center of described bearing body is pilot hole, at bearing body
Surface and be positioned at pilot hole and be formed around circular arc.
According to another embodiment of the invention, the radian farther including described circular arc is 176 °.
The invention has the beneficial effects as follows: the plastic surface bearing of this air-leg uses POM material have the strongest wear-resisting
Characteristic, plane two ends are designed with circular arc, add the intensity of entirety, reduce friction.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structural representation of the present invention；
Fig. 3 is the structural representation of sectional view of the present invention；
Wherein: 1, bearing body, 2, pilot hole, 3, circular arc.
Detailed description of the invention
As shown in Figures 2 and 3, figure includes bearing body 1 and pilot hole 2, and the center of bearing body 1 is pilot hole 2, at bearing
The surface of body 1 and be positioned at pilot hole 2 and be formed around circular arc 3.
The radian of circular arc 3 is 176 ° as shown in Figure 3.The structure of circular arc 3 can increase intensity, reduces friction, service life
Longer.
The overall structure of bearing body 1 is simple, uses POM material, and be formed in one structure, and wearability is higher.
Claims (2)
1. a plastic surface bearing for air-leg, including bearing body (1) and pilot hole (2), it is characterised in that: described bearing body
(1) center is pilot hole (2), on the surface of bearing body (1) and be positioned at pilot hole (2) and be formed around circular arc (3).
2. the plastic surface bearing of air-leg as claimed in claim 1, it is characterised in that: the radian of described circular arc (3) is
176°。
