技术方案：为解决上述技术问题，本发明采用的技术方案为：
一种单活塞杆液压缸，包括缸底、缸筒、缸盖、活塞、活塞杆、耳环、油口、盖口套，所述缸筒后端设置有缸底，所述缸筒前端卡接有缸盖，所述缸盖内设置有活塞杆，所述活塞杆后端设置有活塞，所述活塞杆前端设置耳环；所述缸筒顶部前后各设置有一个油口；所述缸筒与缸盖卡接处设置有盖口套，所述盖口套前端设置有弹簧挡圈，盖口套后端设置有卡键；所述缸盖后端设置有导向结构，缸盖与缸筒接触面设置有O形密封圈，缸盖与活塞杆前端接触面设置有防尘圈，缸盖与活塞杆后端接触面设置有Y形密封圈。
所述活塞与活塞杆后端之间设置有卡键。
所述活塞与活塞杆套接处设置有O形密封圈。
所述活塞与缸筒之间设置有耐磨圈；所述耐磨圈前后两侧均设置有Y形密封圈。
所述缸底、耳环上均设置有销孔，所述销孔内设置有尼龙衬套。
有益效果：本发明提供的一种单活塞杆液压缸，耐磨性好、密封性强、寿命长，且可承受一定的侧向力。
附图说明
图1为本发明的结构示意图。
具体实施方式
下面结合附图对本发明作更进一步的说明。
如图1所示，一种单活塞杆液压缸，包括缸底1、缸筒2、缸盖3、活塞4、活塞杆5、耳环6、油口7、盖口套8，所述缸筒2后端设置有缸底1，所述缸筒2前端卡接有缸盖3，所述缸盖3内设置有活塞杆5，所述活塞杆5后端设置有活塞4，所述活塞杆5前端设置耳环6；所述缸筒2顶部前后各设置有一个油口7；所述缸筒2与缸盖3卡接处设置有盖口套8，所述盖口套8前端设置有弹簧挡圈9，盖口套8后端设置有卡键10；所述缸盖3后端设置有导向结构，缸盖3与缸筒2接触面设置有O形密封圈11，缸盖3与活塞杆5前端接触面设置有防尘圈12，缸盖3与活塞杆5后端接触面设置有Y形密封圈13。
所述活塞4与活塞杆5后端之间设置有卡键10。
所述活塞4与活塞杆5套接处设置有O形密封圈11。
所述活塞与缸筒之间设置有耐磨圈14；所述耐磨圈前后两侧均设置有Y形密封圈13。
所述缸底1、耳环6上均设置有销孔，所述销孔内设置有尼龙衬套15。
具体使用方法如下：缸筒一端与缸底焊接，另一端缸盖与缸筒用卡键、套和弹簧挡圈固定，以便于拆装检修，两端设有油口。活塞与活塞杆利用卡键、卡键帽和弹簧挡圈连在一起。活塞与缸孔采用的是一对Y形聚氨酯密封圈，由于活塞与缸孔有一定间隙，采用由尼龙1010制成的耐磨环定心导向。活塞杆和活塞的内孔由密封圈密封。缸盖设置为导向套结构，用于保证活塞杆不偏离中心，缸盖外径由O形密封圈密封，其内孔则由Y形密封圈和防尘圈防止油外漏和灰尘带入缸内。缸与杆端销孔内设置有尼龙衬套抗磨。
以上所述仅是本发明的优选实施方式，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
