Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Composition graphs 1---shown in Fig. 4, a kind of chair headrest verts tunable arrangement, primarily of two head rest poles 1, " n " shape bending tube 2, rotating shaft 3, collateral fagging 4, limiting bracket 5, rotating shaft return torsion spring 6, outer panel 7, stay bearing plate 8, lower tooth plate 9, upper tooth plate 10, lower tooth plate pull back spring 11, hang the compositions such as pin 12, rivet pin 13, silencing net 14.Orientation all around described below, orientation time all to use is as the criterion.
The right-hand member of bending tube 2 is welded with collateral fagging 4, and head rest pole 1 upper end on right side is provided with flattening portion, and collateral fagging 4 and the head rest pole 1 flattening portion on right side are hinged on the right-hand member of rotating shaft 3.
The left end of bending tube 2 is welded with limiting bracket 5, and head rest pole 1 upper end in left side is welded with stay bearing plate 8 after first flattening again, and limiting bracket 5 and stay bearing plate 8 are hinged on the left end of rotating shaft 3.Limiting bracket 5, stay bearing plate 8 and outer panel 7 are sleeved in rotating shaft 3 from inside to outside successively, are provided with lower tooth plate 9 and upper tooth plate 10 in limiting bracket 5 and the crack of outer panel 7.
Lower end and the stay bearing plate 8 of lower tooth plate 9 are hinged, and lower tooth plate 9 is positioned at the rear of rotating shaft 3 with the hinge-point of stay bearing plate 8.The lower end of lower tooth plate 9 is provided with circular articulated joint 9a, and stay bearing plate 8 is provided with the hinged breach 8a mated with circular articulated joint 9a, circular articulated joint 9a is placed in hinged breach 8a, thus achieves the hinged of lower tooth plate 9 and stay bearing plate 8.
Lower tooth plate 9 engages with upper tooth plate 10, both thickness is equal, upper tooth plate 10 is positioned at the top of lower tooth plate 9, the below of upper tooth plate 10 is provided with engaging tooth, the top of lower tooth plate 9 is provided with engaging tooth, engaging tooth is unidirectional tooth, and after lower tooth plate 9 engages with upper tooth plate 10, upper tooth plate 10 can only lower tooth plate 9 driven forward relatively.Lower tooth plate pull back spring 11 is housed between lower tooth plate 9 and stay bearing plate 8, makes lower tooth plate 9 self-return.Preferably, lower tooth plate pull back spring 11 is torsion spring, but this torsion spring encloses less than one, and one end of this torsion spring hangs in the breach at stay bearing plate 8 top, and the other end of this torsion spring hangs in the bottom notch of lower tooth plate 9 front end, and lower tooth plate 9 needs very little power to reset.Lower tooth plate pull back spring 11 is not limited to torsion spring, as long as other spring of the smooth return of lower tooth plate 9 can be made also can to adopt.
Upper tooth plate 10 is riveted by least two rivet pin 13 that horizontal interval (HI) is arranged be fixed together with outer panel 7, limiting bracket 5, installs anti-rotation while fixing.
The inner side of lower tooth plate 9 is provided with horizontally-guided post 9a, and preferably, lower tooth plate 9 adopts pressed sheet, horizontally-guided post 9a and lower tooth plate 9 integrated punching shaping.Certainly, horizontally-guided post 9a also can be arranged separately, then is welded on the inner side of lower tooth plate 9.
Limiting bracket 5 offers pilot notched 5a, in the pilot notched 5a that horizontally-guided post 9a insertion limiting bracket 5 is offered.The top of pilot notched 5a is cambered surface, and when lower tooth plate 9 moves forward upper tooth plate 10 relatively, and when upper tooth plate 10 and lower tooth plate 9 are in engagement, horizontally-guided post 9a moves backward gradually along top cambered surface in pilot notched 5a.The rear height of pilot notched 5a reduces formation inclined-plane gradually, when upper tooth plate 10 moves to stop bit, horizontally-guided post 9a is positioned at the position, boundary on pilot notched 5a inner top cambered surface and inclined-plane, rear end, if continuation driven forward, horizontally-guided post 9a is then made to continue along inclined-plane, rear end to move backward, because the height on inclined-plane, rear end reduces gradually, lower tooth plate 9 is sunk, and depart from upper tooth plate 10.
Rotating shaft 3 is set with rotating shaft return torsion spring 6.One end of rotating shaft return torsion spring 6 hangs in rotating shaft 3 on vertically disposed extension pin 12, and the other end hangs over the front of limiting bracket 5.Preferably, outside rotating shaft return torsion spring 6, silencing net 14 is also covered with.
Preferably, hang pin 12 and adopt scrollwork spring to make, rotating shaft 3 is provided with extension pin-and-hole, scrollwork spring wrap can install in rear direct insertions extension pin-and-hole fixing.Common extension can certainly be adopted to sell, be weldingly fixed in rotating shaft 3.
In addition, outer panel 7 adopts pressed sheet, and have towards the arc rib 7a of inner side in this pressed sheet upper punch, outer panel 7 is fitted by this arc rib 7a and lower tooth plate 9.Collateral fagging 4, limiting bracket 5 all adopt pressed sheet, and the upper end of collateral fagging 4, limiting bracket 5 is partly wrapped on corresponding bending tube 2 by " U " tee section.
During initial condition (as shown in Figure 3, Figure 4), upper tooth plate 10 meshes together with lower tooth plate 9, and horizontally-guided post 9a is positioned at the front end of pilot notched 5a top cambered surface.
Driven forward bending tube 2, bending tube 2 drives the relative lower tooth plate 9 of upper tooth plate 10 to move forward, often after a mobile tooth, lower tooth plate 9 resets under the effect of lower tooth plate pull back spring 11, then engages with a rear tooth of upper tooth plate 10, often promotes a tooth, can hear " clickly " sound, when unclamping the external force of effect under any state that upper tooth plate 10 engages with lower tooth plate 9, upper tooth plate 10 is motionless with the relative position of lower tooth plate 9, thus achieves the adjustment of unspecified angle.Driven forward bending tube 2, until horizontally-guided post 9a is positioned at the rear end (as shown in Figure 5, Figure 6) of pilot notched 5a top cambered surface, now going up tooth plate 10 still to mesh together with lower tooth plate 9, is stop bit, be also upper tooth plate 10 with lower tooth plate 9 from being engaged to the critical conditions be separated.
If continue driven forward bending tube 2 again, horizontally-guided post 9a moves down (as shown in Figure 7) along inclined-plane, rear end in pilot notched 5a, now, upper tooth plate 10 departs from lower tooth plate 9, can't hear " clickly " sound after, unclamp the external force of effect, bending tube 2 automatically returns to initial condition under the effect of rotating shaft return torsion spring 6.
