AI Technical Summary
[0004]现有的技术中,在使用中虽然可以实现一定的液压缸防护效果,但存在的缺陷是:现有的一体式液压缸缺少输出端保护功能的问题,导致使用的时候容易损伤输出端,影响装置的长期稳定使用,鉴于此,我们提出了一种带有防护结构的一体式液压油缸,解决了上述问题
[0015]一、本实用新型通过将安装柱固定在柱体外壁、连接杆与安装盘连接、伸缩环与连接杆不同高度位置固定的结构设计,在伸缩杆运动时,伸缩环能逐个从安装环伸出,形成动态防护层,有效阻挡泥沙等杂质进入柱体内部,避免杂质对内部零件造成磨损或卡顿,保障装置稳定运行;安装柱位于柱体外圈,可缓冲外界碰撞冲击,保护柱体表面不受损伤,延长柱体使用寿命;这种一体化设计实现了液压缸表面防护功能,简化了设备维护流程,降低了维护成本,极大提升了设备的实用性与可靠性。
