Embodiment
Be described in further detail below in conjunction with accompanying drawing 1,2 and 3 pairs of model utilitys:
A kind of dynamically Hard link one-way air damper.Based on existing air damper, existing air damper basis improves air inlet adjustment structure and forms, comprise housing 1, pull bar 2, piston ring 3 and modulating valve 4; Described pull bar 2 comprises the body of rod 21, and the body of rod 21 front end is provided with pin-and-hole 22, and the body of rod 21 tail end is connected with piston head 23; Described housing 1 is the tubular of one end open, and described housing 1 the other end is provided with the penetration hole 11 matched with the described body of rod 21, the described body of rod 21 is passed from described housing 1 by penetration hole 11; Described piston head 23 is placed in described housing 1 inside and can moves reciprocatingly in housing 1 inside, embeds the piston ring 3 with described housing 1 inner wall sealing in the groove of described piston head 23 outer rim, described piston ring 3 is coated with and is equipped with damp liquid film; Described modulating valve 4 comprises set casing 41 and Y type air-intake valve plate 42, vent 43 is provided with bottom institute's air-intake valve plate 42, the set casing 41 of described modulating valve 4 is fixedly installed on the opening portion of described housing 1, on described air-intake valve plate 42 opening being fastened on described housing 1 to be opened/closed.
When using the utility model, first piston ring 3 is inserted in the corresponding groove of piston head 23 outer rim, and at the even coating damping in piston ring 3 top layer liquid film; Pin-and-hole 22 one end of pull bar 2 is passed by housing from penetration hole 11, the piston head 23 of pull bar 2 is loaded in housing; The opening end of the air-intake valve plate 42 of modulating valve 4 towards housing 1 is fastened on the opening of housing, the set casing 41 of modulating valve 4 is fixedly connected with housing 1.Pin-and-hole 22 is connected with the folding position of parts (as automobile glove box) respectively with housing 1, pull bar 2 is pulled when parts (as automobile glove box) carry out breakdown action, piston ring 3 moves, by pull bar 2, piston ring 3, housing 1 and modulating valve 4 the volume of air chamber that encloses increase, air pressure reduces, at this moment air-intake valve plate 42 is adjacent to housing 1, air is only slowly flowed in air chamber from vent 43, damp liquid forms damping oil film when piston ring 3 moves at housing 1 chamber wall simultaneously, produces damping force.When parts (as automobile glove box) carry out closing motion, piston ring 3 reversing motion, by pull bar 2, piston ring 3, housing 1 and modulating valve 4 the volume of air chamber that encloses reduce, air pressure increases, at this moment air-intake valve plate 42 is separated with housing 1 and forms gap, helps the discharge of gas indoor air, adds the speed that air is discharged, eliminate air pressure resistance, thus make light closedown.
