Description

改进型汽车前挡风玻璃遮阳收卷帘固定装置及收卷帘 技术领域
本发明涉及汽车用品领域，特别涉及一种改进型汽车前挡风玻璃遮阳收卷帘固定装置及收卷帘。
背景技术
随着生活水平的提高，汽车越来越普及，但当前市场上各种汽车在出厂前汽车内部均没有遮阳帘，有些中高档轿车也只有后排左右窗上有遮阳帘，在炎热的夏季，汽车在太阳底下停放一段时间后，车内温度会迅速升高，不仅使人无法适应车内的温度，进入车内前必须先开车窗开空调降温，而且会加速车内各部件的老化，因此很多汽车玻璃上都贴上遮阳膜，但为了视野需求，汽车前挡风玻璃是无法贴膜的，人们通常用遮阳帘来遮住前挡风玻璃，开车时再取下。
申请号为201610942426.8的发明专利公开了一种固定装置，该固定装置的万向连接件采用蛇形管，蛇形管与主杆件之间采用喇叭口和缩口螺母来固定，蛇形管下端采用螺纹与滑动箍套进行固定连接，蛇形管不仅角度调整不方便，而且在长度方向上不能进行伸缩，此外，喇叭口和缩口螺母的固定方式，靠摩擦力来进行固定，固定不够牢固可靠，装在车上长期颠簸后易脱落，影响行车安全，蛇形管两端的固定方式拆卸方式简单，容易被人随意拆卸，影响使用寿命。
