Description of drawings
Structural representation when Fig. 1 is in the gear released state for the utility model;
Structural representation when Fig. 2 is in the gear lock-out state for the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, Fig. 2, the utility model comprises Chair underframe 1, locking tongue 2, gear locking control line 3, control lever 4, torsion spring 5, base station 6, hold-down screw 7, alignment pin 8, spring 9, dog screw 10 etc.Base station 6 is provided with arc bump 6-1 and shell-like projection 6-2; Have through hole 6-21 on the shell-like projection 6-2.The two ends of control lever 4 have through hole 4-1 and 4-2, and the middle part has strip hole slot 4-3.Base station 6 and hold-down screw 7 are fixed on the Chair underframe; Dog screw 10 is fixed on the locking tongue 2.The arc bump 6-1 that gear locking control line 3 is walked around on the base station 6 is connected with through hole 4-1 on the control lever 4; Control lever 4 is set in the shell-like projection 6-2 of base station 6.Alignment pin 8 passes through hole 6-21 on the base station 6 shell-like projection 6-2 and stretches in the strip slotted eye 4-3 on the control lever 4; The through hole 4-2 of control lever 4 other ends and an end hook of torsion spring 5 connect; Torsion spring 5 is set on the hold-down screw 7, dog screw 10 clasp joints on its other end and the locking tongue 2.Spring 9 is set on the control lever 4.
During real work, as tension gear locking control line 3, then control lever 4 is pulled, thus pulling torsion spring 5, and torsion spring 5 drives locking tongue 2 outside motions again and stretches out, and blocks the adjusting rod of swivel chair backrest, makes swivel chair backrest location.When unclamping gear locking control line 3, then under the effect of torsion spring 5 and spring 9, control lever 4 resets, thereby drives locking tongue 2 retractions, and the swivel chair backrest can freely be adjusted angle again.
