Abstract

本实用新型公开了一种LB型搭口活塞环，该活塞环包括环体两端分别设置有L型缺口与B型缺口搭接，所述LB型搭口有两条线接触，L型缺口与B型缺口的拐角均为90度，该活塞环作为内燃机关键零部件之一，使汽缸密封性能更好，更加省油和提高内燃机工作效率。

Description

LB型搭口活塞环
(一)、技术领域：本实用新型涉及一种内燃机活塞环，特别是一种LB型搭口塞环。 
(二)、背景技术：活塞环是内燃机中的关键零部件之一，其密封性能的好坏直接影响内燃机的工作运行。密封性能低，汽缸易产生串气、串油现象，使燃油不能充分燃烧，耗油，且内燃机工作效率低，工作成本高。为了提高活塞环的密封性能，在活塞环的接口处采用LB型搭口是一种较好的技术方案。 
(三)、实用新型内容：本实用新型的目的，设计一种LB型搭口活塞环，提高了密封性能，有利于提高内燃机工作效率，节省燃油，该LB型搭口活塞环采用了L型底面与B型两个圆弧端线接触搭接的结构，把汽缸串气、串油现象控制至最低限度，使燃油得到充分燃烧，使内燃机在整个使用过程中处于高度密封，保持缸压不下降的稳定工作状态。 
本实用新型的技术方案如下：该LB型搭口活塞环，包括环体1，环体1上一端设置有L型缺口2，另一端设置有B型缺口3，L型缺口底面与B型缺口两个圆弧端形成两条线接触。 
所述L型缺口2和B型缺口3的拐角均为90度。 
本实用新型的有益效果是： 
1、提高了密封性能及汽缸压力。 
2、内燃机动力持久强劲，动力性好，载重最大，爬坡力强，提高了效率。 
3、节约燃油，可直接降低工作成本。 
4、废气排放低，利于环境保护。 
(四)、附图说明：图1为本实用新型的主视图。 
图2为本实用新型的附视图。 
(五)、具体实施方式：下面结合附图和实施例对本实用新型作进一步详细说明。 
如图1、2所示，本实用新型的LB型搭口活塞环，包括环体1，环体1上一端设置有L型缺口2，另一端设置有B型缺口3，二者搭接形成L型底面与B型两个圆弧端两条线接触。、 
采用了本实用新型的内燃机动力持久强劲，动力性好，载重量大，爬坡力强，提高了效率，节约燃油，降低了工作成本。 
所述L型缺口2和B型缺口3的拐角不得小于90度。 
所述LB型搭口线接触为两条，也可以为一条和多条。 

Claims (3)

1.LB型搭口活塞环，包括环体(1)，环体(1)上一端设置有L型缺口(2)，另一端设置有B型缺口(3)，其特征在于：所述LB型搭口活塞环是L型缺口与B型缺口搭接。 
2.根据权利要求1所述的LB型搭口活塞环，其特征在于：L型缺口和B型缺口的拐角均为90度。 
3.根据权利要求2所述的LB型搭口活塞环，其特征在于：L型缺口底面与B型缺口两个圆弧端形成两条线接触。
