Abstract

光缆护管端口密封吊圈属于光纤通讯设备技术领域。由俩半圆圈组成。半圆圈的半圆边有吊臂。吊臂梢端有弯钩,可挂在钢护管端口边上。半圆圈的直径边有连边,用螺栓可将俩半圆圈连成一体。半圆圈有直径边有半圆口,可供光缆的贴身塑料护管通过。密封吊圈插装在钢护管端口内,使填塞的防火泥整体密实,不会散碎下坠。用于通讯光缆入户护管端口的密封。

Description

光缆护管端口密封吊圈
技术领域
本发明涉及光纤通讯设备。
背景技术
通讯光缆入户有护管保护,简易办法是光缆穿入塑料护管,塑料护管再穿入钢护管。在钢护管端口填塞防火泥,并加装对开式防雨帽,盖住钢护管端口进行密封。但是由于防火泥没有依托,久之会因风化水浸而散碎下坠失效。进而护管进水引发事故。中国专利ZL2013“光缆护管端口密封托架”,能将防火泥托架在钢护管端口内,防止防火泥的散碎下坠。但在试用中发现,托架上处于护管端口的弦向吊件,影响填入防火泥,进而影响防火泥的密实度。
发明内容
光缆护管端口密封吊圈要解决的技术问题是:不仅防止防火泥散碎下坠,而且要使防火泥填塞方便,填塞密实。采用的技术方案是:在钢护管端口,加装沿钢护管端口内壁下伸的吊臂,吊住一个护圈。护圈中心有可供贴身保护光缆的塑料护管通过。使钢护管内壁与塑料护管外壁之间空无机件,很易塞入防火泥。进而使所填防火泥密实、牢固、持久地装在钢护管端口内。
光缆护管端口密封吊圈(图1)由俩半圆圈3组成。半圆圈3的半圆边有吊臂2。吊臂2梢端有挂钩1,可以挂在钢护管的端口边上。半圆圈3的直径边有折弯90°的连边4。连边4上有连孔5,可用螺栓将俩半圆圈3连成整体。半圆圈3直径边中心有半圆口,可供塑料护管通过。
使用时,1、将两半圆圈3抱住塑料护管,用俩小螺栓通过连孔5,把俩半圆圈3连成一体。2、顺塑料护管下推连成一体的俩半圆圈3,插入钢护管端口内,至吊臂2的挂钩1挂在钢护管的端口边上。3、在吊圈之上,钢护管与塑料护管之间形成的环形凹槽内,密实地填入防火泥,并使上端呈锥形。4、扣合防雨帽,光缆护管端口密封做毕。
光缆护管端口密封吊圈的有益效果是:1、防火泥有吊圈托住,填装时可以填密实,增加密封性;日久散碎,也不会下坠钢护管内,密封持久。2、吊圈之上空无机件,填装防火泥方便快捷。
附图说明
图1示光缆护管端口密封吊圈一半的结构示意图。
图中,1-挂钩,2-吊臂,3-半圆圈,4-连边,5-连孔。
具体实施方式
半圆圈3、吊臂2、挂钩1、连边4用塑料注塑成一体。或者用金属板冲压制成带连边4的半圆圈3后,再在半圆边焊上梢头完成挂钩1的吊臂2。
