The specific embodiment
Shown in Fig. 1-5, office revolving chair governor motion of the present utility model, it comprises pallet gear positioning seat 1, disk cover gear support 2, backrest active iron 3, spring pedestal group 4 and locking mechanism, the middle-end riveted joint of the middle-end of disk cover gear support 2 and pallet gear positioning seat 1, the front end of the rear end of backrest active iron 3 and disk cover gear support 2 is hinged.The rear end of the rear end of disk cover gear support 2 and pallet gear positioning seat 1 and 4 riveted joints of spring pedestal group, the front end of the middle-end of backrest active iron 3 and pallet gear positioning seat 1 is hinged, and governor motion is installed on the seat base, on backrest active iron 3 backrest is installed.
As Fig. 1, shown in 2, described locking mechanism comprises the lock core 13 that is fixedly welded on the pallet gear positioning seat 1, the alveolus locking plate 6 that matches and lock with lock core 13, side at the centre bore of lock core 13 is provided with 3 alveolus that arc is equidistant, lock core 13 be two to establishing composition, disk cover gear support 2 forms a cavity with pallet gear positioning seat 1, two lock cores 13 are arranged in this cavity, on disk cover gear support 2, be provided with perforation, in the perforation of disk cover gear support 2, be provided with locking plate reset drives spring 5, gear regulating block 7 and gear handle 9, locking plate reset drives spring 5 is arranged in the perforation 14 of disk cover gear support 2, gear regulating block 7 one ends embed in the perforation 14 fixing, alveolus locking plate 6 passes in locking plate reset drives spring 5, pass the both sides of disk cover gear support 2 cavitys and pass the lockhole that is arranged on the lock core 13 in the cavity, at the lug boss 15 that is provided with the locking that matches with alveolus on the lock core 13 on the alveolus locking plate 6.On cavity 13, be provided with over cap 12.
