The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, be that the utility model office chair waves structure, comprise seat frame 1, arm-rest frame 2, back rest 3, support 4, rocking carrier 5, described rocking carrier 5 is by connecting rod 6 and " H " shape fixed mount 41 hinged linking of being fixed on the support 4, and so rocking carrier 5 will oscillate with respect to support 4 under the effect that is subjected to external force.The bottom of arm-rest frame 2 is fixed on the last end floor beam 51 of rocking carrier 5.The bottom-hinged of the afterbody of seat frame 1 and back rest 3, its front portion is fixed on the arm-rest frame 2 by " √ " shape support 8.The appropriate location is hinged by the back top of hinge and arm-rest frame 2 below back rest 3.Sidepiece at arm-rest frame 2 has a rocking bar 71, and control is installed in the brake gear 7 on support 4 and the rocking carrier 5, sees Fig. 1, shown in Figure 3.So structure is rocked before and after the people is sitting on the seat frame 1, because action of inertia, rocking carrier just can ceaselessly swing back and forth, thereby has realized the function of rocking chair.The utility model office chair waves structure, on " H " shape fixed mount 41 and rocking carrier 5, brake gear 7 has been installed, this brake gear 7 comprises rocking bar 71, two ends 761,762 are individually fixed in the push rod 76 on " H " shape fixed mount 41, the end 761 of this push rod 76 can be along fixed bar 411 axial displacements on " H " shape fixed mount 41, pull bar 77 is enclosed within on the push rod 76 by hole 771, pass block rubber 75, rocking carrier 5 and be fixed in the pad 74 in rocking carrier 5 outsides and be fixed in capstan winch 72 on the rocking bar 71, fixing with nut 78, spherical recess 741 and shallow slideway 742 that ball 73 is arranged in pad 74 and capstan winch 72 relative one sides, spherical recess 741 is darker, shallow slideway 742 is more shallow, see shown in Figure 6ly, on capstan winch 72, have and ball 73 corresponding spherical recess 721.Rotating rocker 71 like this, pad 74 and capstan winch 72 relative motions, ball 73 skids off spherical recess, enter shallow slideway 742, axial displacement has taken place, increased the relative distance between pad 74 and the capstan winch 72, thereby forced the upper beam 51 of pull bar 77 tension push rods 76 compressing block rubbers 75, implemented braking to rocking carrier 5.

Above-mentioned office chair waves structure, the anterior following of described seat frame respectively is fixed with one " √ " shape support 8 with the arm-rest frame intersection, an inside side has several counterbores 81 on this support 8, on arm-rest frame 2, match a rotating ejection pin device 9 is respectively arranged with " √ " shape support 8, this ejection pin device 9 comprises a sleeve 91, a packing ring 92, a spring 93, an ejection pin 94, the pin tube 96 that also has rotating fixed mount 95 and pass fixed mount 95, through hole 961 is arranged on pin tube 96, and " √ " shape support 8 can pass; Ejection pin 94 is moved in pin tube 96, one end can insert counterbore 81, the other end is drawn by line, control by the end user, see Fig. 2, shown in Figure 4, so the end user can control ejection pin 94 and enter different counterbore 81 on " √ " shape support 8 by the control lead-in wire, thereby 2 upper and lower displacements of solid line arm-rest frame change seat frame and use with the people who adapts to the different bodily forms with the angle of back rest.
