The invention discloses a novel car speed governor-safety tongs linkage mechanism in the field of elevator safety tongs, which comprises a bracket, a linkage rod and two safety tongs linkage mechanisms, the linkage rod transversely penetrates through the two ends of the bracket, and the two safety tongs linkage mechanisms are in mirror symmetry on the two sides of the bracket and are connected into a whole through the linkage rod. The safety gear linkage mechanism is provided with a safety gear, a guide rail groove is vertically formed in the safety gear, a fixed wedge block is arranged on one side of the guide rail groove of the safety gear, a through groove is formed in the other side of the guide rail groove of the safety gear, a movable wedge block is slidably connected into the through groove, and the movable wedge block is fixedly connected with a Z-shaped lifting arm. The end, away from the movable wedge block, of the lifting arm is fixedly connected with the linkage rod, the lifting arm at the end is close to the bracket, and a lifting pin connected with a speed limiter installed on an elevator car is arranged in the middle of the lifting arm. According to the device, the interaction space of the lifting arms can be reduced in a limited mode, the elevator installation space is released, and the device can be suitable for installation and use of elevators with smaller sizes.

    本方案公开了电梯安全钳领域的一种新型轿厢限速器‑安全钳联动机构,包括托架、联动杆和两个安全钳联动机构,所述联动杆横向贯穿托架的两端,两个所述安全钳联动机构镜像对称于托架的两侧,且通过联动杆连接为一体,所述安全钳联动机构设有安全钳,所述安全钳竖向开设有导轨槽,所述安全钳的导轨槽的一侧设有固定楔块,另一侧设有通槽,通槽内滑动连接有活动楔块,所述活动楔块固定连接有“Z”字形提拉臂,所述提拉臂远离活动楔块的一端与联动杆固定连接,且此端的提拉臂贴近托架,所述提拉臂的中部设有与安装在电梯轿厢上的限速器连接的提拉销。该装置能够有限减小提拉臂的互动空间,释放电梯安装的空间,能够适用于更小体积的电梯安装使用。
