Abstract

本实用新型涉及一种大口径燃气管用防尘盖,包括端口封环、凹形塞体和密封环,端口封环设置在凹形塞体的外端口,若干密封环设置在凹形塞体的外侧壁上;其特征在于它包括一拉拔片,拉拔片设置在端口封环的外侧壁上,在拉拔片设有一拉拔孔。本实用新型具有将防尘盖从大口径燃气管的管口中轻松方便摘除的优点。

Description

大口径燃气管用防尘盖
技术领域
本实用新型涉及一种防尘盖,尤其涉及一种大口径燃气管用防尘盖。
背景技术
目前大口径燃气管用防尘盖用于封装在大口径燃气管的两端的管口中,从而在大口径燃气管的运输和存储过程中防止灰尘和雨水进入大口径燃气管内造成的污染;大口径燃气管用防尘盖包括端口封环、凹形塞体和密封环,端口封环设置在凹形塞体的外端口,若干密封环设置在凹形塞体的外侧壁上;在使用时将凹形塞体塞入大口径燃气管的管口中,密封环处于凹形塞体与大口径燃气管的内壁之间,端口封环与大口径燃气管的管口外端贴紧;在使用大口径燃气管时需人工摘除大口径燃气管用防尘盖,由于大口径燃气管的口径达200mm以上,使得大口径燃气管用防尘盖对应的直径也很大,而且大口径燃气管用防尘盖在大口径燃气管的管口中塞的很紧密,从而在人工摘除大口径燃气管用防尘盖时非常的费劲及不方便,从而需要使用一些薄形的辅助工具塞入端口封环与大口径燃气管的管口之间的间隙中将大口径燃气管用防尘盖撬出,在此过程中可能对大口径燃气管的管口造成损伤。
发明内容
针对以上缺点,本实用新型的目的在于提供一种能从大口径燃气管的管口中轻松方便摘除的大口径燃气管用防尘盖。
本实用新型的技术内容为,一种大口径燃气管用防尘盖,包括端口封环、凹形塞体和密封环,端口封环设置在凹形塞体的外端口,若干密封环设置在凹形塞体的外侧壁上;其特征在于它包括一拉拔片,拉拔片设置在端口封环的外侧壁上,在拉拔片设有一拉拔孔。
本实用新型与现有技术相比所具有的优点是:本实用新型能便于大口径燃气管用防尘盖被人工轻松方便的从大口径燃气管管口中摘除。
附图说明
图1为本实用新型的结构示意图。
图2为图1的俯视图。
图3为本实用新型的另一结构示意图。
图4为图3的俯视图。
具体实施方式
如图1和图2所示,一种大口径燃气管用防尘盖,包括端口封环1、凹形塞体2和密封环3,端口封环1设置在凹形塞体2的外端口,若干密封环3设置在凹形塞体2的外侧壁上;其特征在于它包括一拉拔片4,拉拔片4水平设置在端口封环1的外侧壁上,在拉拔片4设有一拉拔孔4.1。
如图3和图4所示,一种大口径燃气管用防尘盖,包括端口封环1、凹形塞体2和密封环3,端口封环1设置在凹形塞体2的外端口,若干密封环3设置在凹形塞体2的外侧壁上;其特征在于它包括一拉拔片4,拉拔片4垂直设置在端口封环1的外侧壁上,在拉拔片4设有一拉拔孔4.1。
本实用新型的工作原理为:在摘除大口径燃气管用防尘盖时,只需人员将手指伸入拉拔孔4.1中后勾住拉拔片4,然后就能轻松方便的将大口径燃气管用防尘盖从大口径燃气管的管口中取出。
