一种缓降型举升器

Abstract

本实用新型涉及抬升器技术领域，尤其涉及一种缓降型举升器。它包括一对导柱，两根导柱的同时设置在底座上，两根导柱的顶部通过倒勾相连接，两根导柱上活动设置有主壳体，主壳体的正面设置有L形托举板，主壳体内设置有顶压弹簧一，顶压弹簧一顶部设置有举升块，举升块水平套设在两根导柱外侧，主壳体还设置有顶压弹簧二，顶压弹簧二顶部设置有锁紧块，锁紧块斜向卡设置两根导柱外侧，主壳体的背面设置有握把，握把上设置有缓降组件，主壳体上活动设置有扳机，扳机位于握把的下方。通过缓降组件的拨动轮、拨动销、翘杆等结构配合，使主壳体在下降过程中呈现下降一段距离停一下的间歇式运动，降低了设备磨损，延长了举升器的使用寿命。
