Retaining shoulder type vibration reduction fastener
The invention discloses a retaining shoulder type vibration reduction fastener which comprises an upper base plate; a lower base plate; the lower base plate is provided with a first transverse stop shoulder and a second transverse stop shoulder; the upper base plate is provided with a first transverse limiting surface and a second transverse limiting surface; the first transverse stop shoulder andthe first transverse limiting surface are limited through a first transverse stop block, and the second transverse stop shoulder and the second transverse limiting surface are limited through a second transverse stop block; the first transverse stop block is provided with a first matching limiting face making contact with the first transverse limiting face, and the second transverse stop block isprovided with a second matching limiting face making contact with the second transverse limiting face. The first transverse limiting face and the second transverse limiting face are both first wedge-shaped faces, and the first matching limiting face and the second matching limiting face are both second wedge-shaped faces matched with the first wedge-shaped faces. The matching difficulty among theupper base plate, the transverse stop block and the lower base plate is reduced, and the transverse limiting capacity is improved; the tooth matching effect between the distance adjusting cover plateand the lower base plate is improved; and the distance adjusting cover plate is prevented from deflecting during installation.
本发明公开了一种挡肩式减振扣件，包括上垫板；下垫板；下垫板具有第一横向挡肩、第二横向挡肩；上垫板具有第一横向限位面、第二横向限位面；第一横向挡肩和第一横向限位面通过第一横向挡块限位，第二横向挡肩和第二横向限位面通过第二横向挡块限位；第一横向挡块具有与第一横向限位面相接触的第一匹配限位面，第二横向挡块具有与第二横向限位面相接触的第二匹配限位面；第一横向限位面、第二横向限位面均为第一楔形面，第一匹配限位面、第二匹配限位面均为与第一楔形面匹配的第二楔形面。本发明降低了上垫板、横向挡块和下垫板之间的配合难度，提高了横向限位能力；提高了调距盖板和下垫板之间的齿牙配合效果；防止调距盖板在安装时发生偏斜。
