Fig. 1 is outline drawing of the present utility model, shows the state after the utility model boom guy type air damper has assembled.
The major character of each constituent part is as follows:
As shown in Figure 3, cylindrical shell 6, its inside is provided with cavity, and bottom is provided with cylindrical shell uropore 11, and cylindrical shell 6 outer wall upper and lower end are respectively provided with a mounting hole 9, cylindrical shell 6 and are fixed on by mounting hole 9 and screw on the screw column 25 of gloves casing 23; Be positioned at cylindrical shell 6 upper end mounting hole 9 upsides, cylindrical shell 6 outer walls are provided with the cylindrical shell hook that can prevent that bracing wire from coming off; Cylindrical shell top is provided with cylindrical shell hole clipping 29, is positioned at two side walls, connects cover 2 for the grab being provided with by cover; Cylindrical shell 6 bottoms are provided with afterbody hole clipping 10, are positioned at the both sides of cylindrical shell uropore 11, for fixing inlet valve 8.
As shown in Figure 4, piston 4 is provided with hook hole 15, for bracing wire 1 is installed; Piston 4 bottom surfaces are provided with exhaust port 17, and damper is by the outside exhaust of this exhaust port 17; Piston 4 is provided with tongue piece hole 16, is positioned at the piston 4 one side sidewalls of the annular groove 33 of piston, passes this tongue piece hole 16 for the tongue piece 18 of O shape circle 5, and O shape circle 5 is installed on the annular groove 33 of piston 4.
As shown in Figure 5, be provided with the tongue piece 18 of valve function in the middle of O shape circle 5, tongue piece 18 is assemblied on piston 4 through the tongue piece hole 16 of piston 4, and tongue piece 18 is covered on the exhaust port 17 of piston; Piston 4 is in the time that cylindrical shell 6 inner chambers move, and O shape circle 5 plays outside with cylindrical shell 6 internal face seal actions, realizes the valve function of exhaust when tongue piece 18 plays the closed exhaust port 17 in piston when realizing from cylindrical shell 6 bottom inflows or opening.
As shown in Figure 6, inlet valve 8 is provided with grab 20, is positioned at the both sides of inlet valve 8, assembles for the afterbody hole clipping 10 of same cylindrical shell 6; Inlet valve 8 is provided with inlet hole 19, is positioned at inlet valve 8 tops, and boom guy type damper is by these inlet hole 19 air inlets, and the size of inlet hole affects the size of damping force.Under cylindrical shell 6 constant diameter, inlet hole 19 is less, and the damping force of generation is larger, and damping is more obvious, and inlet hole 19 is larger, and the damping force of generation is less, and damping is more not obvious.When glove box lid deadweight and load change are when larger, can select the inlet valve 8 of different pore size inlet hole, with the unlatching glove box lid that remains a constant speed; Inlet valve 8 is provided with positioning bar 21, is positioned at the both sides on inlet valve 8 tops, rises positioning action is installed; Inlet valve 8 is provided with opening slot 22, is positioned at positioning bar 21 both sides of inlet valve 8 below; Inlet valve 8 is plastic inlet plug 8, and while being installed into vent plug 8, inwardly resiliently deformable of the both sides of opening slot 22, is convenient to inlet valve grab 20 and snaps in afterbody hole clipping 10.
