Description

一种连接刚性杆件的折叠接头
【技术领域】
本发明涉及一种折叠接头， 尤其是一种连接刚性杆件的折叠接头。 【背景技术】
在很多领域需要使用折叠接头， 如： 折叠自行车、 折叠帐篷、 建筑用的 架、 健身器材等。 现有的折叠接头有些操作筒便快捷， 但结构偏复杂， 成本 较高； 还有些折叠接头结构简单， 但操作不够方便。
【发明内容】
本发明的目的就是要克服上述不足， 提供一种结构简单、 成本低且操作 简便快捷的连接刚性杆件的折叠接头。
本发明的目的是通过如下技术方案实现的： 本发明连接刚性杆件的折叠 接头， 包括前折叠体， 后折叠体， 前折叠体与后折叠体的一端通过铰轴销铰 接， 此外， 在后折叠体的另一端以锁销铰接了一个锁紧钩， 锁紧钩自由端呈 钩状， 另一端通过至少一个弹性体与后折叠体相连， 锁紧钩可绕锁销中心转 动。
与现有技术相比较， 本发明的优点在于： 因为后折叠体的另一端铰接了 锁紧钩， 两折叠体合拢过程中前折叠体触碰并推动后折叠体的锁紧钩令其张 开， 待合拢时， 在弹簧力作用下， 锁紧钩自动复位， 将合拢后的两个折叠体 自动锁紧。 其锁紧动作能自动完成， 操作非常简捷， 所述的接头零件少， 结 构简单， 成本也较低。
下面结合附图和实施例对本实用新型作进一步的说明： 【附图说明】
图 1为折叠接头合拢前的示意图；
图 2为折叠接头合拢后的示意图；
图 3为带调节螺杆的锁紧钩的示意图； 【具体实施方式】
本发明一种连接刚性杆件 9 , 1 0的折叠接头， 包括前折叠体 2、 后折叠 体 6 , 前、 后折叠体 2 , 6的一端通过铰轴销 1铰接， 在后折叠体 6的另一端 以锁销 3铰接了一个锁紧钩 4 , 锁紧钩 4 自由端呈钩状， 另一端通过一个或 一个以上的弹性体 5与后折叠体 6相连， 锁紧钩 4可绕锁销 3中心转动。
当需要合拢该装置时， 只需要将前折叠体 2、 后折叠体 6相互碰撞， 锁 紧钩即会在弹性体 5的作用下自动开合， 勾紧前折叠体 2 , 连接刚性杆件的 折叠接头即实现闭合； 当需要打开该装置时， 向弹性体 5施力使其压缩， 通 过杠杆作用， 即可使锁紧钩 4钩状部分抬起， 连接刚性杆件的折叠接头即告 打开。 '
为了增强本发明的整体刚性， 可在后折叠板 6上朝向前折叠板 2的一面 设一台阶 7 , 如此， 当两个折叠体 2 , 6合拢时， 台阶 7抵紧在两者之间， 使 两者更为牢固。
上述的弹性体 5可灵活采用多种元件， 可仅用一个压簧 5 , 也可以仅用 一个扭簧 8， 还可以同时使用两个弹簧。 本实施例采用的是压簧 5 , 另外在锁 销 3上还设有扭簧 8 , 对锁紧钩 4施力。
为进一步加固本发明的连接效果， 还可在锁紧钩 4的后端开设螺孔， 用 一调节螺杆 11插置入该螺孔中， 另设一贯穿锁销 3的螺钉 12 , 由该螺钉 12 与调节螺杆 11连接夹持锁销 3。 如此， 转动调节螺杆 11可调整锁紧钩 4相 对锁销 3移动， 以保证锁紧钩 4与前折叠体 2钩紧。
由于本发明结构简单，应用本发明可使操作更为快捷，成本也大大节省。
