Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: because the movement of the extended bush and the torsion spring are not limited, when the adjustment lever is rotated, the torsion spring will drive the movement of the extended bush, and the movement of the extended bush and the torsion spring will The movement of the extended bush and the position of the torsion spring will change, which will cause the torsion spring to no longer touch the lifting pressure plate, so that the chassis of the swivel chair cannot be adjusted, and the product quality will be reduced.

Abstract

The invention relates to the technical field of swivel chairs, in particular to a swivel chair chassis which comprises a base, and a taper pipe is arranged on the base; an adjusting rod is arranged onthe base, and a lifting pressing plate is arranged on the adjusting rod; the base is provided with a pin shaft, the pin shaft is sleeved with a torsional spring block, and the torsional spring blockis provided with a first through hole connected with the pin shaft in a sliding mode. A third through hole for the pin shaft to penetrate through is formed in the base; a first groove is formed in thelifting pressing plate, a second groove is formed in the base, and one end of the torsional spring block is clamped in the second groove; the torsional spring at the end, away from the second groove,of the torsional spring block is located in the first groove. The first purpose of the invention is to prevent the torsion spring block from moving so as to improve the product quality; and the second purpose is to provide a swivel chair chassis mounting process to improve the mounting efficiency.

Description

technical field [0001] The invention relates to the technical field of swivel chairs, in particular to a swivel chair chassis and an installation process thereof. Background technique [0002] The swivel chair chassis support is called 19 support, also known as butterfly support, which is the most important part of the swivel chair chassis. The swivel chair chassis has a wide range of uses. Its main function is to cooperate with the air rod to realize the lifting, rotation, free and easy of the chair, the locking function of the normal position of the swivel chair and to connect the swivel chair base and the lower air rod. [0003] At present, the Chinese utility model with the authorized notification number CN208176391U discloses a lifting control device for the chassis of a swivel chair, including a movable seat, a cone tube, an adjustment rod, a lifting pressure plate, an extended bush, a bush, a rivet, a torsion spring, and the cone tube is fixed. On the movable seat, t...
