横街条幅张紧器
本技术涉及一种横街条幅张紧器。
技术介绍
条幅作为一种广告或宣传的载体,街头巷尾随处可见,对于横街悬挂的条幅,都是在条幅的四个角各连接一钢丝,然后钢丝绑扎在电线杆或者树枝上,在高空进行作业,还得保证条幅要拉紧而不会松垮,十分的困难和不便,需要一种简单的机构来实现快速的悬挂横街的条幅。
技术实现思路
本技术针对上述现有技术存在的问题做出改进,即本技术所要解决的技术问题是提供一种横街条幅张紧器,结构简单,拆装方便。为了解决上述技术问题,本技术的技术方案是:一种横街条幅张紧器,包括一竖杆,所述竖杆一侧上下部分别设置有一个抱箍,所述竖杆另一侧上下部分别设置有一根支杆,所述支杆端部设置有一箍圈,两箍圈之间套设有一转轴,所述转轴侧壁上下部分别设置有放置箍圈的环形凹槽,所述转轴外径大于箍圈内径,以使转轴绕箍圈转动,所述转轴在两箍圈之间的侧壁上设置有让条幅穿过的条缝,所述转轴侧壁上设置有若干个穿过条缝的螺纹孔,所述螺纹孔内设置有穿过条缝的沉头螺钉,所述转轴侧壁上下部均设置有若干个定位槽,所述竖杆上下部分别设置有一定位螺纹孔,所述定位螺纹孔内螺接有定位螺栓,所述定位螺栓端部 ...
