The invention discloses a grooved wheel lock. The grooved wheel lock is composed of a bottom plate (1), a central column (2), a lower nylon sleeve (3), a grooved wheel (4), an upper nylon sleeve (5), a screw (6), a lower tension spring fixing column (7), an upper tension spring fixing column (8), a tension spring (9), a crank arm (10), a stepped shaft screw rod (11), a lock pin (12), a shaft sleeve (13) and a nut (14), in a door closing state, when a vertical pull rod (70) moves upwards, the lock pin (12) is disengaged from a lower notch (41) of the grooved wheel (4), at the moment, a rotating door is pushed, and the rotating door can be opened and unlocked; and in the door opening state, the rotating door is pushed, when an impact face (45) of the grooved wheel (4) collides with a fixed door pin (60), the grooved wheel (4) rotates anticlockwise, then under the downward pulling force effect of the vertical pull rod (70), and when the lock pin (12) enters the lower notch (41) of the grooved wheel (4), the rotating door is locked and does not rotate any more.
本发明公开了一种槽轮锁,由底板(1)、中心柱(2)、下尼龙套(3)、槽轮(4)、上尼龙套(5)、螺钉(6)、下拉簧固定柱(7)、上拉簧固定柱(8)、拉簧(9)、拐臂(10)、阶梯轴螺杆(11)、锁销(12)、轴套(13)和螺母(14)组成,在关门状态时,当竖直拉杆(70)向上运动时,锁销(12)从槽轮(4)的下槽口(41)中脱出,这时推动转动门,转动门可以被打开,完成解锁,在开门状态时,推动转动门,当槽轮(4)的撞击面(45)与固定门销(60)相碰撞时,槽轮(4)逆时针转动,然后,在竖直拉杆(70)向下的拉力作用下,锁销(12)进入到槽轮(4)的下槽口(41)中时,转动门将被锁住不再转动。
