Abstract

一种折叠接头,由连接板、连杆铰接构成四连杆式折叠接头,在两个连杆相互铰接处其中一个连杆的铰接点之外向延长构成手柄。所述的接头加长了作为开锁的手柄的力臂,便于抓持开锁十省力。

Description

一种折叠接头
技术领域
本实用新型涉及连接两段杆(管)件的折叠接头。
背景技术
中国专利96236902.0号给出了一种四连杆式的折叠接头,其两个连接板上分别铰接一个连杆,两连杆另一端铰接,当两个连接板合拢时,两个连杆并拢基本平行于被连接的杆件处于接头外构成手柄,搬动两连杆即可打开合拢的折叠接头。由于这种四连杆结构使连杆的长度尺寸受到限制,作为折叠自行车上使用的折叠接头连接板的尺寸不能太大,使连杆的尺寸相应也不能加长,两个连杆并拢时作为开锁的手柄、其尺寸太小则力臂很小,因折叠接头锁紧力很大,作为开锁的手柄力臂很小,所以打开接头时很费力。另外,两连接板合拢时,两连杆基本平行于被连接的杆件且相互间隙很小,体壮手指较粗者较难插入,若捏着连杆搬动仍然很吃力。
发明内容
本实用新型之目的是给出一种开锁时省力的四连杆式折叠接头。
本实用新型所述的折叠接头,有连接板、连杆构成,在两个连杆的铰接处其中一个连杆的铰接点之外向外延长构成加长柄。
所述的折叠接头,由于一个连杆在铰点外向外延长,但并未改变四连杆式机构的各铰接点的尺寸关系,但却加长了连杆作为手柄时的力臂,两者的间距增大,便于插入手指。所述的折叠接头,便于抓持,且力臂较长,开锁时十分省力。
附图说明
图1所述接头的主视图;
图2是图1的K向视图;
图3是展开状态图。
具体实施方式
连接板1、连杆2相互铰接构成的折叠接头,在连杆2的铰点之外向外延长构成加长柄3。
