Abstract

The invention relates to the technical field of office furniture accessories, in particular to an automatic rotating air pressure rod. The automatic rotating air pressure rod comprises an outer sleeve and a rod core, wherein the rod core is placed in the outer sleeve; symmetrical conical-surface arc-shaped reset guide sleeves, reset bearings, plane bearings, guide bearings, springs and supporting seats are arranged in the outer sleeve in sequence; an aluminum pipe is fixed to the rod core and is arranged in the inner holes of the reset guide sleeves and the reset bearings. The automatic rotating air pressure rod has specific direction resilience and can be automatically adjusted to the original rotating angle after a chair is used, so that the uniformity and the convenience are realized; the comfort and the efficiency are improved through soft rotating and lifting movement.

Description

technical field [0001] The invention relates to an air pressure rod, in particular to an automatic revolving air pressure rod. Background technique [0002] At present, the lifting air pressure rod is widely used in daily life, especially in office furniture. It is the main component of the office swivel chair. The rotation angle of the chair used in the prior art is not uniform, which affects the overall aesthetic effect. And the angle needs to be manually adjusted, which lacks simplicity. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects, and provides an automatic swirling air pressure rod. [0004] In order to overcome the defects existing in the background technology, the technical solution adopted by the present invention to solve its technical problems is: the self-rotating pneumatic rod includes an outer casing and a rod core, the rod core is placed in the outer tire tube, and the inside of the outer casing is sequen...
