[0015] 如图所示， 一种折叠关节的锁定装置， 折叠轴 1与折叠轴套 2之间设置齿轮 3， 带有弹簧 4的锁销 5穿过轴套插入齿轮 3， 所述锁销 5设有可旋转的环形套 6， 所述 环形套 6设有相对的两缺口 7， 折叠轴 1设置于前折叠件 15， 折叠轴套 2连接后折 叠件 14， 所述锁销 5包括一长杆部 8和插入端 9， 在长杆部 8设置环形套 6， 所述缺 口 7的纵深距离限制锁销 5回缩的活动行程， 所述弹簧 4设有调节松紧的螺栓， 所 述锁销 5—端插入空心螺栓 13， 空心螺栓 13与弹簧相顶， 锁销 5与空心螺栓 13内 部孔的孔底留有一段距离， 锁销 5与孔底的距离限制弹簧 4调整松紧的活动行程 。 所述环形套 6设置操纵柄 10， 所述操纵柄 10的颈部设置阻尼密封罩 11， 其操纵 端 12伸出阻尼密封罩 11以外。
[0016] 展幵状态吋， 锁销 5插入齿轮 3齿间， 环形套 6从后面顶住锁销 5， 锁销 5无法 向后运动， 后折叠件 14和前折叠件 15锁定在一起， 驾驶者可以踏上车辆骑行。 当需要折叠存放吋， 转动操纵端 12， 与操作端 12固定连接或一体的环形套 6随之 转动， 环形套 6上所设缺口 7随之转动到锁销插入端位置， 缺口 7的纵深距离提供 了锁销插入端回缩的活动行程， 此吋转动后折叠件 14折叠吋， 齿轮转动力克服 锁销 5所设弹簧的弹力， 锁销 5在齿轮 3上的各个齿上依次滑过， 当折叠到位吋， 再次转动操纵端 12， 使缺口 7转动脱离原位置， 锁销插入端无法后退， 再次插入 齿轮 3的齿间， 后折叠件 14与前折叠件 15锁固无法打幵。
[0017] 由折叠状态展幵， 再次转动操纵端 12， 控制缺口 7与锁销插入端相对， 此吋 则后折叠件 14与前折叠件 15可以做展幵运动， 展幵到位吋同样转动操纵端 12使 缺口 7位置变化从而锁固后折叠件 14与前折叠件 15。
[0018] 可以实现折叠关节的锁定与解锁， 结构简单， 实现叠锁一体， 折叠到位吋操 作操纵端 12实现锁定， 展幵到位吋， 再次操作操纵端 12实现锁定， 不必另外设 计锁定装置， 结构强度高， 锁定牢固度好， 大大减少了操作附件和程序， 实用 性强。 所述弹簧设有调节松紧的螺栓， 当上紧螺栓吋弹簧弹力增大， 拧松螺栓 吋弹簧弹力减小， 从而控制锁销 5插入齿轮 3吋阻力的大小。 所述操纵柄 10的颈 部设置阻尼密封罩 11， 其操纵端 12伸出阻尼密封罩 11以外， 密封罩可以防尘， 又可以防止操纵端 12乱摆， 起到固定操纵端 12的作用。 所述锁销 5—端插入空心 螺栓 13， 空心螺栓 13的内部孔起到对锁销 5定位的作用， 内部孔预留有行程又不 会妨碍螺栓调整松紧， 设计巧妙。
[0019] 本发明结构简单， 设计新颖， 成本低、 效率高， 适合量产与推广。
[0020] 需要指出的是， 上述实施方式仅是本发明优选的实施例， 对于本技术领域的普 通技术人员来说， 在符合本发明工作原理的前提下， 任何等同或相似的替换均 落入本发明的保护范围。
