Abstract

孔端隐形密封盖结构，包括端盖、钢球、密封圈、紧定螺钉、套筒。所述孔端隐形密封盖结构的端盖通过孔轴配合在套筒孔内，端盖的外圆上设置有半圆环槽，对应位置的套筒的内孔上设置有同样大小的半圆环槽，端盖和套筒的半圆环槽形成完整圆环，所述的套筒上在环槽位置开有紧定螺钉的螺纹内孔与环槽相通，钢球从螺纹内孔进入端盖和套筒形成的完整圆环，端盖与套筒轴向限位，端盖端部与套筒端面平齐无痕迹，所述的密封圈装配在端盖的内侧外圆上承担密封作用，紧定螺钉在钢球装配后锁紧。

Description

孔端隐形密封盖结构
技术领域
本实用新型涉及一种端盖密封结构，属于机械装置，主要用于套筒或箱体孔端的密封。
背景技术
在套筒或箱体孔的端部密封应用上，大部分采用外露台阶端盖密封、螺纹配合密封装置，当需要孔端平整无外露零件时，台阶端盖就无法实现。
发明内容
为实现孔口无外露的平整密封，本实用新型提供一种结构简单、装拆方便、成本低廉的孔端隐形密封盖结构，通过在内孔和端盖上同时开有半圆环槽，放入钢球限位，达到定位密封作用。
本实用新型的技术方案是：用于孔口无外露的孔端隐形密封盖结构，包括端盖、钢球、密封圈、紧定螺钉、套筒。所述孔端隐形密封盖结构的端盖通过孔轴配合在套筒孔内，端盖的外圆上设置有半圆环槽，对应位置的套筒的内孔上设置有同样大小的半圆环槽，端盖和套筒的半圆环槽形成完整圆环；所述的套筒上在环槽位置开有紧定螺钉的螺纹内孔与环槽相通，钢球从螺纹内孔进入端盖和套筒形成的完整圆环，端盖与套筒轴向限位，端盖端部与套筒端面平齐无痕迹；所述的密封圈装配在端盖的内侧外圆上承担密封作用，紧定螺钉在钢球装配后锁紧。
附图说明
附图1是本实用新型孔端隐形密封盖结构示意图。
具体实施方式
参见附图，本实用新型提供一种孔端隐形密封盖结构，包括端盖1、钢球2、密封圈3、紧定螺钉4、套筒5。
所述孔端隐形密封盖结构的端盖1通过孔轴配合在套筒5孔内，端盖1的外圆上设置有半圆环槽，对应位置的套筒5的内孔上设置有同样大小的半圆环槽，端盖1和套筒5的半圆环槽形成完整圆环。
所述的套筒5上在环槽位置开有紧定螺钉4的螺纹内孔与环槽相通，钢球2从螺纹内孔进入端盖1和套筒5形成的完整圆环，端盖1与套筒5轴向限位，端盖1端部与套筒5端面平齐无痕迹。
所述的密封圈3装配在端盖1的内侧外圆上承担密封作用，所述的紧定螺钉4在钢球装配后锁紧。
