【技术实现步骤摘要】
本技术属于自行车或电动车领域,涉及车梯,尤其是一种滚轮式车梯。
技术介绍
车梯是稳定、定位自行车及电动车的用具,包括单支车梯及双支车梯。在使用车辆 时,用脚将车梯放下即可;在停止使用时,用脚将车梯支起即可。由于电动车自身重量较大, 人们在放下车梯及支起车梯时,需要较大的力量用脚蹬踹方可实现,而且,在放下车梯及支 起车梯时需要提起车辆方可完成,比较费力;尤其对于在车辆上载有货物情况下,这种车梯 结构更加费力,也容易发生侧翻。通过检索,发现一篇与专利申请相近的公开专利,一种省力滚轮车梯 (CN201580466U),包括支撑杆、锁板,在两侧支撑杆之间固装有对称的加强筋,在两侧支撑 杆与对称固装的加强筋之间分别安装两个滚轮,两个滚轮位于支撑杆的下端前部。本滚轮 车梯在车梯的支撑杆与加强筋之间所形成的两个间隙中对称固装了两个滚轮,在放下车梯 及支起车梯时,利用滚轮平稳过渡,直至启动或者驻车,实现了以较小的脚踢力即可释放车 梯,非常省力。上述对比专利的缺点是1、滚轮是固定的,不起支撑作用,因此不能作为车梯使 用;2、滚轮的作用是可以减轻支起车梯时的力量,同时,也可以在车 ...
【技术保护点】
1.一种滚轮式车梯,包括支撑杆、锁板、锁板弹簧,在支撑杆的左端上部安装锁板及锁板弹簧,在支撑杆的右端上部安装辅助弹簧,支撑杆由钢筋揋制而成且由两侧对称的竖直杆与水平杆构成,其特征在于:在支撑杆所制的两侧的竖直杆下部均揋制有一水平短杆,在该两个水平短杆下端均通过滚轮架安装有一滚轮,该两个滚轮至少一个为自锁滚轮,在安装自锁滚轮的滚轮架与自锁滚轮之间的滚轮架里侧固装一弹性摩擦片。
