Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Shown in referring to Fig.1~Fig. 4, the fastening of base armrest of seat is linked with damping in a kind of embodiment provided by the utility model
Mechanism, which is characterized in that including handrail 1, supporting plate 8 and damp hinge 3, handrail 1 is hinged by damp hinge 3 and supporting plate 8.
Further, one end of damp hinge 3 is fixed on supporting plate 8 by screw, is equipped with and is passed through on handrail 1 and supporting plate 8
Perforation, the other end of damp hinge 3 are horizontally through the through hole on handrail 1 and supporting plate 8, connect locking with nut 6；Pass through nut
6 are locked.
Further, the number of screw is 2, respectively the first screw 4 and the second screw 5.
Further, the both ends of the through hole of handrail are equipped with handrail side cover；Two handrail side covers will pass through hole and cover, and avoid
Damp hinge 3 and nut 6 are exposed, block dust, keep shape more beautiful, and two handrail side covers are respectively the first handrail side cover 2
With the second handrail side cover 7.
Further, as shown in Fig. 5~Fig. 7, damp hinge 3 includes outer cylinder 9, and the outer cylinder 9 is closed at both ends, in outer cylinder 9
Equipped with cavity 10, damping oil 11 is equipped in cavity 10, the volume of the damping oil 11 is less than the volume of cavity 10, along outer cylinder 9
Axis is equipped with the shaft 12 across outer cylinder 9, and the shaft 12 is located at the part in cavity 10 equipped with damping vane 13, the damping
Blade 13 has at least two panels, and is circumferentially uniformly distributed in shaft 12；Bolt 21 is adjusted by turning, to control the body in air bag 20
Product, when 20 place space of air bag reduces, air bag 20 is outward being pushed up connecting rod 17, and damping vane 13 stretches out the length of shaft 12 at this time
Elongated, damping force increasing is spent, and reverse operating adjusts bolt 21,20 place space of air bag becomes larger, due to the work of return spring 19
With damping vane 13 becomes smaller to recycling, damping force, and this programme structure is simple, can be very convenient by turning adjusting bolt 21
Adjusting damp hinge 3 damping force.
Further, the shaft 12 is provided with control hole 14 along axis, and described 14 one end of control hole, which is equipped with, to be open, and described turn
Placing groove 15 is provided on the outer wall of axis 12, the tail portion of the damping vane 13 is arranged in placing groove 15, the placing groove 15
Bottom is provided with through-hole 16, and the every damping vane 13 is equipped with the connecting rod 17 across through-hole 16, institute close to one end of shaft 12
It states connecting rod 17 and the sliding of through-hole 16 is arranged, the part that the front of the connecting rod 17 is protruded into control hole 14 is provided with annular groove, the company
It is cased with snap ring 18 on the annular groove of bar 17, is equipped with return spring 19 between 14 inner wall of snap ring 18 and control hole on the connecting rod 17.
Further, it is equipped with air bag 20 in the control hole 14, the front end of the connecting rod 17 is withstood on air bag 20, the control
