摘　　要：一种单作用机械锁紧液压缸,负载压缩活塞杆退回,液压缸活塞杆采用棱台形状,依靠棱台具有斜度的侧面与楔块的楔紧作用达到锁紧目的,这种方式可明显提高锁紧力及锁紧质量;同时使用常用材料便可加工制造,成本较低,而且锁紧可靠,使用寿命长。A kind of single function mechanical lock hydraulic cylinder,Load compression piston rod returned,and with a trustum of a pyramid piston rod,which via the two slops between trustum of a pyramid and wedge block to wedge-caulking the rod, This way can obviously improve the lock force and lock quality. At the same time they can use common materials manufacturing it, with low cost, and lock, reliable, and long service life.
