Abstract
The utility model relates to office furniture accessory technical field, especially a kind of air pressure rod with plastic spacer, comprise outer tube and piston rod, described outer tube center is provided with piston rod, be provided with outer tube metallic gasket on the left of described piston rod, on the right side of described piston rod, be provided with bearing metal pad, between described outer tube metallic gasket and bearing metal pad, be provided with plastic spacer, described plastic spacer side is provided with guiding step, and the material of plastic spacer is nylon.Present arrangement avoids piston rod eccentric swing and the friction of outer tube pad centre bore when operating, and plastic spacer uses nylon material, increase wear-resisting and soft flexible, improve air pressure rod to rock back and forth in use and the noise phenomena of rotating chair, increase buffering, to a kind of comfortable sensation of user, improve the comfort level of chair, can office revolving chair be widely used in.
Description
Technical field
The utility model relates to office furniture accessory technical field, especially a kind of air pressure rod with plastic spacer.
Background technology
Current lifting air pressure bar is used widely in daily life, that applies in office furniture especially is more extensive, it is the main composition part of office revolving chair, the sub-assembly that the plane bearing used in lifting air pressure bar in prior art is ball type, and use pad to be all metallic gasket, metallic gasket in use easily rubs and makes a noise, secondly piston rod top and outer tube pad centre bore gap larger, easily to swing, problems such as will wearing and tearing is rotated for a long time between the two when swinging larger, the complaint of client is caused to raise, quality cost is caused to increase.
Utility model content
In order to overcome existing deficiency, the utility model provides a kind of air pressure rod with plastic spacer.
The utility model solves the technical scheme that its technical problem adopts: a kind of air pressure rod with plastic spacer, comprise outer tube and piston rod, outer tube center is provided with piston rod, outer tube metallic gasket is provided with on the left of piston rod, bearing metal pad is provided with on the right side of piston rod, be provided with plastic spacer between outer tube metallic gasket and bearing metal pad, plastic spacer side is provided with guiding step.
According to another embodiment of the present utility model, the material comprising plastic spacer is further nylon.
The beneficial effects of the utility model are, present arrangement avoids piston rod eccentric swing and the friction of outer tube pad centre bore when operating, and plastic spacer uses nylon material, increase wear-resisting and soft flexible, improve air pressure rod to rock back and forth in use and the noise phenomena of rotating chair, increase buffering, to a kind of comfortable sensation of user, improve the comfort level of chair, can office revolving chair be widely used in.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 plastic spacer structural representation.
1. outer tubes, 2. piston rod in figure, 3. outer tube metallic gasket, 4. bearing metal pad, 5. plastic spacer, 6. lead step.
Detailed description of the invention
Structural representation of the present utility model as shown in Figure 1, Figure 2, a kind of air pressure rod with plastic spacer, comprise outer tube 1 and piston rod 2, outer tube 1 center is provided with piston rod 2, be provided with outer tube metallic gasket 3 on the left of piston rod 2, on the right side of piston rod 2, be provided with bearing metal pad 4, between outer tube metallic gasket 3 and bearing metal pad 4, be provided with plastic spacer 5, plastic spacer 5 side is provided with guiding step 6, and the material of plastic spacer 5 is nylon.
Guiding step 6 is contained in the centre bore of air pressure rod outer tube metallic gasket 3, guiding step 6 external diameter and the perfect adaptation of air pressure rod outer tube metallic gasket 3 centre bore, doing so avoids air pressure rod piston rod 2 eccentric swing and the friction of outer tube metallic gasket 3 centre bore when operating, and use nylon material, utilize the wear-resisting and soft flexible of of nylon material itself, improve air pressure rod to rock back and forth in use and the noise phenomena of rotating chair, increase buffering, to a kind of comfortable sensation of user, improve the comfort level of chair, can office revolving chair be widely used in.
More than illustrate the utility model just illustrative; and it is nonrestrictive; those of ordinary skill in the art understand; when not departing from the spirit and scope that claims limit; many amendments, change or equivalence can be made, but all will fall in protection domain of the present utility model.
