Abstract

带有密封性的加机油口盖,其特征为:由加机油口盖体、顶盖、橡胶密封垫组成,橡胶密封圈固定在顶盖上,顶盖集成在加机油盖中。本实用新型具有成本低,密封性好,特别易于批量生产的特点。

Description

带有密封性的加机油口盖
技术领域
本实用新型属于发动机气缸盖的技术领域,特别涉及一种带有密封性的加机油口盖。
背景技术
发动机加机油口的位置多数布置在气缸盖罩盖上。部分中重型车为避免在车上加机油时翻驾驶室,需额外布置机外加机油口。而加机油口盖的结构是否合理,特别是密封性,将直接影响到发动机寿命;曲轴箱为负压时导致灰尘经加机油口盖进入曲轴箱,曲轴箱为正压时混合气经加机油口盖排入大气,导致曲轴箱排放物的增加。
发明内容
针对上述结构缺陷情况,本实用新型目的是提供一种带有密封性的加机油口盖。
本实用新型的技术方案是这样实现的:
带有密封性的加机油口盖,其特征为:由加机油口盖体、顶盖、橡胶密封垫组成,橡胶密封圈固定在顶盖上,顶盖集成在加机油盖体中。
本实用新型具有成本低,密封性好,特别易于批量生产的特点。
附图说明
图1为本实用新型的结构示意图。
图2为本实用新型的剖面示意图;
图3为本实用新型的剖面示意图。
具体实施方案
下面结合附图详细说明本实用新型的具体实施方案。
带有密封性的加机油口盖,其特征为:由加机油口盖体1、顶盖2、橡胶密封垫3组成,橡胶密封圈3固定在顶盖2上,顶盖2集成在加机油口盖体1中。
实施例:
本实用新型应用于一汽集团公司中重型车上。
本实用新型的带有密封性的加机油口盖,顶盖2上均匀分布12个外翻的钩,与加机油口盖体1相匹配,即顶盖的设计采用缺口倒枪刺结构,顶盖2可在加机油口盖体1内自由转动,在旋紧加机油口盖体1时顶盖2不旋转,橡胶密封垫3与机油管口5接触,延长了橡胶密封垫3的使用寿命,使得密封更可靠。
加机油口盖体1的外壁均匀分布有6个凹槽4,这种结构即增加整体强度又使外型造型美观。

Claims (3)
