Abstract

本实用新型涉及一种饮水用硬管，包括胶合树脂中间层，所述胶合树脂中间层的外部包覆有PVC树脂外层，胶合树脂中间层的内部设有热塑性树脂内层，所述胶合树脂中间层与热塑性树脂内层和PVC树脂外层结合为一体。本实用新型的有益效果为：解决了现有的双层结构硬管存在有不同材质间因结合性不佳，导致内外层易因热胀冷缩而分离及不易生产等缺陷，其构造简单、结合性好、制造容易且易于连续生产。

Description

一种饮水用硬管
技术领域
本实用新型涉及一种饮水用硬管。
背景技术
目前已知的饮水用硬管，结构是利用内、外管的结合处作为环形齿状条纹，或在内管表面设有数个突体，而使其内、外管可相互穿套结合成一体，但此种结构在实际的生产中易发生所使用的模具的型体较为复杂不易生产，而且该双层结构硬管存在有不同材质间因结合性不佳，导致内外层易因热胀冷缩而分离及不易生产等缺陷。
实用新型内容
本实用新型的目的是提供一种饮水用硬管，以克服现有的双层结构硬管存在有不同材质间因结合性不佳，导致内外层易因热胀冷缩而分离及不易生产等缺陷的不足。
本实用新型的目的是通过以下技术方案来实现：
一种饮水用硬管，包括胶合树脂中间层，所述胶合树脂中间层的外部包覆有PVC树脂外层，胶合树脂中间层的内部设有热塑性树脂内层，所述胶合树脂中间层与热塑性树脂内层和PVC树脂外层结合为一体。
本实用新型的有益效果为：解决了现有的双层结构硬管存在有不同材质间因结合性不佳，导致内外层易因热胀冷缩而分离及不易生产等缺陷，其构造简单、结合性好、制造容易且易于连续生产。
附图说明
下面根据附图对本实用新型作进一步详细说明。
图1是本实用新型实施例所述的一种饮水用硬管的结构示意图。
图中：
1、热塑性树脂内层；2、PVC树脂外层；3、胶合树脂中间层。
具体实施方式
如图1所示，本实用新型实施例所述的一种饮水用硬管，包括胶合树脂中间层3，所述胶合树脂中间层3的外部包覆有PVC树脂外层2，胶合树脂中间层3的内部设有热塑性树脂内层1，所述胶合树脂中间层3与热塑性树脂内层1和PVC树脂外层2结合为一体。
