High-speed railway locking gear ring lock
The invention discloses a high-speed railway locking gear ring lock. The gear ring lock comprises an outer shell, and a lock cylinder arranged in the outer shell; one end of the lock cylinder is a square end, and the other end is a thread section; a ring rib projected outwards is arranged in the connected place of the square end of the lock cylinder with the thread section; the lock cylinder is limited in the outer shell through the ring rib; a spring is arranged between the outer shell and the ring rib of the lock cylinder; a lock shell sleeves the lock cylinder; a lock bolt penetrating through the lock cylinder is arranged between the ring rib of the lock cylinder and the square end; an inner gear ring is arranged on the inner wall of the opening end of the outer shell; an outer gear ring matched with the inner gear ring is arranged on the outer wall of the lock shell; when the lock pin is positioned in a locking position of a lock hole on the lock shell, the inner gear ring of the outer shell is engaged with the outer gear ring of the lock shell; and when the lock pin is in an open position of the lock hole on the lock shell, the inner gear ring of the outer shell is deviated from the outer gear ring of the lock shell. The high-speed railway locking gear ring lock achieves a further locking function, is excellent in looseness preventing, vibration preventing and vibration resisting effects and high in stability, and prominently improves the safety.
本发明公开了一种高铁防松齿圈锁，该齿圈锁包括外壳、设于外壳内的锁芯，锁芯一端为方头，另一端为螺纹段，锁芯的四方头与螺纹段的连接处设有外凸的圈筋，锁芯通过圈筋限位于外壳内；外壳与锁芯的圈筋之间设有弹簧，锁芯外套设锁壳，锁芯的圈筋与方头之间设有穿过锁芯的锁销；外壳的开口端内壁上设有内齿圈，锁壳的外壁上设有与内齿圈相匹配的外齿圈；锁销位于锁壳上锁孔的锁闭位时，外壳的内齿圈与锁壳的外齿圈啮合；锁销位于锁壳上锁孔的打开位时，外壳的内齿圈与锁壳的外齿圈脱开。本发明的高铁防松齿圈锁具有进一步锁闭的功能，防松、防振、抗振效果好，稳定性高，安全性显著提高。
