Description of drawings
Fig. 1 is the decomposing schematic representation of the office chair headrest mechanism structure of the utility model position-adjustable;
Fig. 2 is the part section reference view that described office chair headrest is regulated;
Fig. 3 is the view that the rotation of described office chair headrest is regulated;
Fig. 4 is that described office chair headrest is installed in the schematic diagram on the office chair backrest.
The specific embodiment is described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
The office chair of the utility model position-adjustable headrest mechanism as shown in Figures 1 to 4, comprises head rest body 1, is fixed on gripper shoe 2 and trace 3 on the chair back 8, and assign in the guide groove 21 in gripper shoe 2 bottom of described trace 3.In addition, also comprise device for regulating rotary 5, this device for regulating rotary 5 comprise screw rod 51, about two locating cones 52, about two adjusting knobs 53 and arc tumbler 54.
Described tumbler 54 upper ends and head rest body 1 are rotatably connected, and all have polygon through hole 542 in the middle of its two ends, below 541; Be provided with two sections external screw threads 511,512 that direction is opposite at described screw rod 51 near the place, two ends, in described locating cone 52, be provided with the internal thread 521 suitable with described external screw thread 511,512, one section 522 of this locating cone 52 is truncated cone, and the cross section of another section 523 is the polygon adaptive with described polygon through hole 542; The top 31 of described trace 3 has through hole 32, and these through hole 32 two ends have and the suitable tapering of the frustoconical section 522 of locating cone 52.
Described screw rod 51 passes through the through hole 542 at two ends, described tumbler 54 below and the through hole 32 of described trace 3; The frustoconical section of two described locating cones 52 screws in the through hole 32 of described trace 3, and its polygon section embeds respectively in the polygon through hole 542 of described tumbler 54; Described two adjusting knobs 53 respectively with screw rod 51 two ends clampings.The cross section of the polygon section of described tumbler 54 both ends through holes 541 and locating cone 52 is regular hexagon or octagon.Two outsides at described trace top 31 are extended with one section circular arc wall 33, so that assembling.
As shown in Figure 2, during turn knob 53, this knob 53 drives described screw rod 51 rotations.Owing to two sections screw threads 511,512 that direction is opposite are arranged on the screw rod 51, when screw rod 51 rotations, about two locating cones 52 simultaneously inwardly or motion outwardly.Shown in Fig. 2 a, the through hole 32 in described locating cone 52 and the trace 3 fits like a glove, and locating cone 52 is fixed; Because the polygon through hole at the polygon end of locating cone 52 and two ends, tumbler 54 below is adaptive so that locating cone 52 can not relatively rotate part 54 radial motions, so tumbler 54 also was fixed when described locating cone 52 was fixed.When turn knob 53 makes the state of locating cone 52 shown in Fig. 2 b, described locating cone 52 no longer with described trace 32 in through hole 32 inwalls coincide, described tumbler 54 is loosened and can be rotated relative to trace 3.
As shown in Figure 4, the upper end of described tumbler 54 and head rest body 1 are rotatably connected and form first pivot, and lower end and trace 3 rotatable adjustings are connected to form second pivot.Fix second pivot, pull headrest main body 1 and make its i.e. first pivot rotation of described relatively tumbler 54 rotations, can change the radian that contacts of headrest main body 1 and user's head.Regulate first pivot, loosen second pivot simultaneously and regulate the rotation of second pivot, the front and back position that can change the headrest main body is to satisfy the instructions for use under user's different conditions.The design at dual rotary center is as the joint of mechanical arm.By the complementary interaction of two pivots, enlarged the movable scope of head rest body greatly, thereby guaranteed head rest body is adjusted to the required the most comfortable position of user.
As shown in Figure 4, owing to trace 3 assigns in the gripper shoe 2, and gripper shoe 2 is fixedlyed connected with the chair back 8, rotates so tumbler 54 rotates to be equal to relative to the chair back 8 relative to trace 3.Shown in Fig. 3 a and 3b, tumbler 54 is controlled in 40 degree relative to the angle that the chair back 8 rotates.
As depicted in figs. 1 and 2, the cell wall 22 on described gripper shoe guide groove 21 both sides is the waveform cell wall, two transverse concave grooves 34 about the lower end of described trace is provided with, one next door 35 is arranged between two grooves 34, all be placed with keeper 6 in two grooves 34, accompany spring 7 between each keeper 6 and the next door 35, the outside of described keeper 6 is provided with circular arc positioning convex 61, and described positioning convex 61 is suitable with waveform cell wall 35.Shown in Fig. 2 a～2c, as user up or down during other positions of pull head pillow main body 1 or headrest, driving spring 7 by trace 3 shrinks, keeper 6 is moved to crest spring 7 diastoles then by the trough of waveform groove, keeper 6 slips into last one or next trough from crest, thereby realizes the lifting and the location of headrest.Described elevation positioning structure is succinct, practical, and is easy to assembly.
