Efficient elevator car intercepting device

The utility model provides an efficient elevator car intercepting device. The problem that a safety device of an existing electrical structure has the hidden danger of protection failure is solved. The clamping block is pushed by the boosting block to move towards the guide rail, and one end of the clamping block extends into the through hole to be in contact with the intercepting block clamped onthe guide rail; the downward impact force of the elevator car is transmitted to the intercepting clamping block, and then the elevator car which falls quickly is buffered and intercepted through theclamping head and the second groove which are in interference fit, so that the elevator car is stopped quickly, and the structure is simple and practical. 本实用新型提供了一种高效电梯轿厢拦截装置。它解决了现有电气结构的安全装置皆有保护失效的隐患的问题。本实用新型通过助推块推动卡块向导轨移动并使卡块的一端伸入通孔内与卡接在导轨上的拦截块接触，电梯轿厢向下的冲击力传递到拦截卡块上，再通过过盈配合的卡接头与第二凹槽对快速下坠的电梯轿厢进行缓冲拦截，使电梯轿厢快速停止，结构较为简单实用。
