The invention discloses a clockwork spring type buffer and an elevator. The clockwork spring type buffer comprises a buffer mechanism and a limiting mechanism. The buffering mechanism is arranged at the bottom of an elevator car and comprises a clockwork spring, the outer end of the clockwork spring is fixed, the inner end of the clockwork spring is fixedly connected with a rotating body, the rotating body can be connected to the elevator car in the mode of rotating around a horizontal axis, and the rotating body is provided with a transmission circumferential face annularly arranged around the horizontal axis. A plurality of meshing teeth are arranged on the transmission circumferential surface; the limiting mechanism is arranged at the bottom of an elevator shaft and comprises a vertically-arranged transmission plane, and a plurality of meshing teeth are arranged on the transmission plane. And the meshing teeth on the transmission circumferential surface are meshed with the meshing teeth on the transmission plane. The clockwork spring type buffer is small in impact in the buffering process, and damage to an elevator car is avoided; the clockwork spring type buffer occupies a small space in an elevator shaft.

    本发明公开一种发条式缓冲器及电梯,该发条式缓冲器包括缓冲机构和限位机构;所述缓冲机构设置在电梯轿厢底部,所述缓冲机构包括发条弹簧,所述发条弹簧的外端固定,而其内端固定连接有转动体,所述转动体可绕一水平轴线转动地连接于电梯轿厢,所述转动体上设有绕该水平轴线环设的传动圆周面,所述传动圆周面上设有多个啮合齿;所述限位机构设置在电梯井道的底部,所述限位机构包括竖向设置的传动平面,所述传动平面上具有多个啮合齿;所述传动圆周面上的啮合齿与所述传动平面上的啮合齿啮合。该发条式缓冲器在缓冲过程中的冲击小,避免对电梯轿厢造成损害;该发条式缓冲器在电梯井道所占用的空间小。
