Abstract

一种卷闸门链条式防挂封口码,它由单个成沟槽型封口码1串联连接后而组成的链条式的封口码,其特征在于:封口码1的沟槽上端开口宽,下端开口窄而成锥形沟槽。本实用新型与现有的封口码相比,易开起,无挂滞,结构简单易制造。

Description

卷闸门链条式防挂封口码
本实用新型涉及卷闸门部件,具体地说就是卷闸门链条式封口码。
在现用的卷闸门封口码是一圆形凹弧槽并且单口封口于卷闸门的页片的两端,特别是在上下开起门时,容易在门框槽口端产生挂滞现象,有时,若稍不对称地上下拉动,很容易卡住使得开起时费时费力。
为了克服上述之不足,本实用新型的目的在于提供一种用于卷闸门的链条式防挂封口码,克服了卷闸门开起关闭过程中的挂滞现象。
一种卷闸门链条式防挂封口码,它由单个成沟槽型封口码1串联连接后而组成的链条式的封口码,其特征在于:封口码1沟槽上端开口宽,下端开口窄而成锥形沟槽。封口码1沟槽的一边缘设有固定板2,且板上开有固定孔3。封口码1沟槽的上端的侧边留有缺口4,槽底的上下端各开有连结孔5。
本实用新型与现有的封口码相比,易开起,无挂滞、结构简单易制造。
附图为本实用新型的结构示意图。
实施例:按照附图设计制造本实用新型产品,根据所用卷闸门页片的多少,用铁片折成如图1的单个封口码1,留出固定板2,开好固定孔3,留好缺口4,开好连接孔5,再将每个封口码用销钉串联连接起来即为本实用新型。
