Retaining shoulder type damping fastener suitable for in-line spike holes
The invention discloses a retaining shoulder type vibration reduction fastener suitable for in-line spike holes. The retaining shoulder type vibration reduction fastener comprises an upper base plate;a lower base plate; the upper base plate is provided with a first through hole, the lower base plate is provided with a second through hole, and the first through hole and the second through hole arematched with the in-line spike holes; a first transverse blocking shoulder and a second transverse blocking shoulder are symmetrically arranged on the first side of the lower base plate, and a thirdtransverse blocking shoulder and a fourth transverse blocking shoulder are symmetrically arranged on the second side of the lower base plate; a first elastic strip rear seat and a second elastic striprear seat are symmetrically arranged on the first side of the upper base plate, and a third elastic strip rear seat and a fourth elastic strip rear seat are symmetrically arranged on the second sideof the upper base plate; the first elastic strip rear base extends to form a first transverse limiting face, the second elastic strip rear base extends to form a second transverse limiting face, the third elastic strip rear base extends to form a third transverse limiting face, and the fourth elastic strip rear base extends to form a fourth transverse limiting face. The shoulder arrangement problem of the in-line shoulder damping fastener is solved, and shoulder and self-locking structural design of a fastener system is achieved.
本发明公开了一种适用于直列式道钉孔的挡肩式减振扣件，包括上垫板；下垫板；上垫板设置第一通孔，下垫板设置第二通孔，第一通孔和第二通孔与直列式道钉孔匹配设置；下垫板第一侧对称设置有第一横向挡肩和第二横向挡肩，下垫板第二侧对称设置有第三横向挡肩和第四横向挡肩；上垫板第一侧对称设置有第一弹条后座和第二弹条后座，上垫板第二侧对称设置有第三弹条后座和第四弹条后座；第一弹条后座延伸形成第一横向限位面，第二弹条后座延伸形成第二横向限位面，第三弹条后座延伸形成第三横向限位面，第四弹条后座延伸形成第四横向限位面。本发明解决了直列式挡肩减振扣件的挡肩排布问题，实现了扣件系统的挡肩和自锁结构设计。
