Description
Technical field
The utility model relates to the supporting parts of a kind of swivel chair, specifically is a kind of swivel chair pallet that connects the seat support and the chair back.
Background technology
In the prior art, it is existing to be used in the supporting pallet of swivel chair, its governor motion is a handle when pulling up and down, by the roller roof pressure gasket compression stage clip that connects handle, regulates locking or loosen the brake sheet, the chair back of swivel chair is swung within the specific limits, though structure is tightly firmly short, brings two problems simultaneously: the one, the compression of stage clip is a transients, it is when pressing also or loosening, waving of the chair back is very rapid, brings great incompatible sense for the first user or the person of being unfamiliar with; The 2nd, adopt brake(-holder) block locking, brake(-holder) block and pad have relatively more noisy mutual grating when the chair back is swung.
Summary of the invention
The utility model provides a kind of anti-automatic resilience, eliminates the governor motion of friction, its objective is to overcoming the deficiency that existing pallet exists, and makes the user of pallet feel more comfortable.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of swivel chair pallet, comprise tray rack, one end of described tray rack is via first hinged chair back sliding seat that is provided with, be equipped with adjusting rod on the side panel of described tray rack, adjusting rod end in the described tray rack is provided with the flexible adjustment seat, be provided with second on the tray rack side panel above the described adjusting rod, the elongated hole of following tooth bar one end is set on second, the following tooth bar other end via the 3rd tail end that is hinged on chair back sliding seat; With following tooth bar over against at the hinged end that upper rack is set of tray rack, the other end of upper rack is a free end and towards chair back sliding seat, the arc bottom of flexible adjustment seat is connected to the free end of upper rack via steel wire.
The technique effect that the utility model presents is that operation drives the flexible adjustment seat by adjusting rod during adjusting rod and sways, and realizes the gear motion of two tooth bars, thus the locking of regulating the swivel chair backrest with loosen.Specifically, when two tooth bars were in non-engagement state, chair back sliding seat can freely swing, because down tooth bar is to adopt straight pin to connect, so there is not grating during swing; When rotating counterclockwise the flexible adjustment seat, steel wire pulling upper rack is swung and is meshed with following tooth bar, and this moment, chair back sliding seat was in locking state; When going back to the flexible adjustment seat clockwise again, because two tooth bars are in engagement, chair back sliding seat can not got back to original state immediately, but need apply a power backward to chair back sliding seat, chair back sliding seat just can be got back to original position, thereby realizes the anti-automatic resilience function of the utility model mechanism.Therefore the utlity model has characteristics such as reasonable in design simple in structure.
