The hydraulic lifesaving dilator is composed of a housing, a large oil cylinder, a small oil cylinder, a large piston, a small piston, an oil storage cavity, a one-way valve, an oil return valve, a tension arm, a tension arm hinge, and a power arm. Work is the process, use the insert dynamic front arm expander between two rod window fence, a hand holding dilator, another hand push forward and push the push rod, a push-pull rod, constantly hydraulic oil into the oil tank, the pressure effect of piston cylinder in the hydraulic oil, promote the piston rod to move forward. The force arm of the top rod is pushed open to both sides, and the power arm and the tension arm are a whole, so the force arm is opened. The open stretch arm opens the window fence to both sides of the larger gap, allowing people to drill through and quickly leave the scene of the fire. In the invention, the opening force of the tension arm is increased by using the hydraulic and mechanical double saving way, and the liquid pressure is increased by the way of small piston forward and backward movement, which has the characteristics of convenient operation and labor saving.

液压式救生扩张器
本专利技术涉及一种液压式救生设备,具体涉及一种液压式救生扩张器。
技术介绍
现代人居住条件越来越好,而且人们为了防盗,常常在自家的窗户等安装栅栏式的防盗装置。这样的装置虽然能起到防盗作用,但是也给住户自己带来一些不利因素,比如,当火灾发生时,如果门道不能走时,窗户也被防盗栅栏封死,而且栅栏式的防盗装置用普通的工具是无法打开的,如果不能及时离开危险现场,是很危险的。本专利技术液压式救生扩张器,可以很好地解决这个问题,本扩张器可以在很短的时间内弄开铁栅栏,让自己得以很快离开危险现场。
技术实现思路
为了解决此类问题,本专利技术液压式救生扩张器,由外壳,大油缸,小油缸,大活塞,小活塞,储油腔,单向阀,回油阀,张力臂,张力臂铰链,动力臂等组成。所述外壳前端固定有张力臂铰链轴,所述张力臂铰链轴将两个张力臂穿在一起形成张力臂铰链,所述张力臂铰链轴上固定有张力臂回位扭簧,所述大油缸内放置有大活塞,大活塞的一端与大活塞顶杆相连,大活塞顶杆和动力臂相接触,当大活塞向前移动时,可以推开动力臂向两边移动,带动张力臂张开。所述大油缸体下端设有进油通道,所述进油通道中部侧面设 ...
