The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing the adjustable seat of the utility model backrest inclination angle.
Embodiment: as Fig. 1-shown in Figure 10, the adjustable seat of backrest inclination angle described in the utility model, mainly by chair pin 1, chassis 2, be installed in support 3 and backrest 4 and cushion 5 compositions on the chassis 2, backrest 4 is installed in support 3 rear ends, the strong point 50 is installed in the middle part of support 3 before the cushion 5, the back strong point 51 supports by the connecting rod 6 that is hinged on the chassis 2, cushion 5 can produce interlock with the angle variation of backrest 4, improve comfort level, change the preceding strong point 50 installation sites of cushion 5, during backrest 4 hypsokinesis, the angle of inclination of its cushion 5 varies in size, it is forward more that the strong point 50 is installed in the position of support 3, and cushion 5 angles change more little.Be provided with torsion mechanism 7 and fork mechanism 8 in the chassis 2, wherein, torsion mechanism 7 has the hexagonal bar 70 that is supported on 2 both sides, chassis, the front end sleeve of support 3 is connected on the both ends that hexagonal bar 70 stretches out the outside, chassis, hexagonal bar 70 is positioned at chassis 2 and is socketed with the left and right sides locating piece 73 that has a main torsion glue 71 and an auxiliary torsion glue 72 at least and be positioned at torsion glue both sides, present embodiment has adopted two auxiliary torsion glue 72 and 71, two auxiliary torsion glue 72 of a main torsion glue to be positioned at the both sides of main torsion glue 71.Main torsion glue 71 has vestibule 710 and back ear 711, auxiliary torsion glue 72 has vestibule 720 and back ear 721, the back ear 711 of main torsion glue 71 and the back ear 721 of auxiliary torsion glue 72 are on same angle, one pin 74 is installed on the left and right sides locating piece 73, the back ear of torsion glue withstands on when initial position on this pin 74, makes backrest 4 have a primary stress when initial position.Be provided with support member 75 on the vestibule 710 of main button power glue 71, the torsion that produces deformation by main button power glue 71 makes backrest 4 have the dynamics of leaning on after the initial minimum.Fork mechanism 8 uses comparatively common on the automatic clutch device, mainly by rotary handle 80, be socketed in the fork of forming by fixedly fork 81 and movable fork 82 on the rotary handle 80, movable fork 82 is provided with block 820, when rotary handle 80 rotates, when fixedly the driving inclined-plane 810 of fork 81 contacts with the pushing block of movable fork 82, driving activity fork 82 is away from fixing fork 81, block 820 on the movable fork 82 is resisted against vestibule 720 bottoms of auxiliary torsion glue 72, increase the torsion of torsion glue, because auxiliary torsion glue 72 has two tools, so the fork that cooperates with auxiliary torsion glue 72 also needs two groups.Movable fork 82 is positioned at the fixedly inboard of fork 81, is provided with the back-moving spring 83 that two movable forks 82 are resetted to fixing fork 81 directions between movable fork 82.In order to make seat have the torsion of many grades of different sizes, the width of two auxiliary torsion glue 72 is not of uniform size, the auxiliary torsion glue 72 in left side is bigger than auxiliary torsion glue 72 width on right side, about two groups of forks, it drives the different rotary angle position that inclined-plane 810 is positioned at rotary handle 80, makes the angle of its clutch action inconsistent.As shown in Figure 7, when rotary handle 80 is positioned at initial position, be one grade, movable fork 82 is under the effect of back-moving spring 83 about this moment, and block 820 does not all contact with auxiliary torsion glue 72, has only main torsion glue 71 to produce torsion.Rotate rotary handle 80 certain angles, not being given in the right side among the pushing block figure of the movable fork 82 in right side fixedly is moved to the left under acting on the driving inclined-plane 810 of fork 81, block 820 is resisted against vestibule 720 bottoms of the auxiliary torsion glue 72 in right side, and be second gear this moment, and torsion increases; Rotate to an angle again, the movable fork 82 on right side resets under back-moving spring 83 effects, block 820 leaves auxiliary torsion glue 72 positions, right side, the pushing block of the movable fork 82 in left side fixedly moves right under the effect on the driving inclined-plane 810 of fork 81 in the left side, block 820 is resisted against vestibule 720 bottoms of the auxiliary torsion glue 72 in the left side, be third gear torsion this moment, because the auxiliary torsion glue 72 in left side is bigger than the width of the auxiliary torsion glue 72 in right side, so the relative second gear of torsion also wants big; Be rotated further rotary handle 80, the bottom of two auxiliary torsion glue 72 vestibules 720 about the pushing block of two movable forks 82 all is against about making, at this moment, three torsion glue all work, and the torsion maximum is the fourth gear structure.In order to regulate the initial position stress intensity of backrest 4, support member 75 of the present utility model adopts the adjusting screw(rod) 75 that is installed on the chassis 2 to regulate.
The hexagonal bar 70 that the utility model patent adopted can also be non-revolution structures such as four angular poles, triangle pole, adopts these structures, all belongs to equivalent technical solutions of the present utility model, falls into protection domain of the present utility model.
