Description

一种能减缓推杆冲击的连接器锁线操作机构 技术领域
本实用新型涉及机械领域，尤其涉及一种能减缓推杆冲击的连接器锁线操作机构。
 背景技术
现有技术中的连接器锁线操作机构，其推杆为一体式结构。
 技术问题
当转动推杆解除锁定使弹片放松回位时，没有考虑弹性部件瞬间迅速回弹的弹力对推杆造成的冲击。当推杆遇到的冲击较大时，推杆的操作端会对操作人员造成伤害。
 技术解决方案
本实用新型提供了一种用于解决回弹瞬间冲击过大而对人员造成伤害的技术问题的能减缓推杆冲击的连接器锁线操作机构。
本实用新型的技术方案：机构包括装置本体，本体上可安装沿弧形轨道转动连的推杆以及围绕圆孔转动的凸轮，所述推杆内侧具有扇形缺口可容纳所述凸轮且留有富余的空间，所述推杆与凸轮配合并且两者可绕其共同的旋转轴转动，所述凸轮的两侧分别与所述推杆、弹片接触，通过转动所述推杆从而推动所述凸轮转动，所述凸轮转动可以下压并锁定所述弹片，所述弹片锁线孔完全打开以放入或取出导线，通过向另一方向转动所述推杆并推动所述凸轮以放开所述弹片，使所述弹片锁线孔闭合以锁紧。
优选的，弹片上具有可容纳导线的锁线孔。
优选的，本体具有可容纳所述推杆的弧形轨道和固定所述凸轮的圆孔。
优选的，推杆内侧具有可容纳所述凸轮的扇形缺口，并且推杆内侧扇形缺口与凸轮旋转轴同心；设置有扇形缺口的圆心角大于所述凸轮外形的圆心角，由此形成的空间用于缓冲弹片回弹时产生的冲击。
优选的，推杆底部设置有与凸轮的凹槽配合的凸筋。
优选的，凸轮两侧与所述本体接触设置有与本体的限位挡墙结构配合的限位钉。
优选的，推杆具有与用于限定其在本体弧形轨道中的弧形凸筋。
优选的，本体具有减缓凸轮冲击的阻尼挡墙。
 有益效果
本实用新型的有益效果是：（1）推杆与凸轮两件式结构，推杆内侧具有可容纳凸轮的扇形缺口且扇形缺口的圆心角大于凸轮外形的圆心角，凸轮在推杆扇形缺口内可来回转动；（2）转动推杆从而推动凸轮旋转以下压弹片，直至限位钉与本体上的限位挡墙接触；此时凸轮处于稳态，压紧并锁定弹片至最低点，弹片上的锁线孔被完全打开便于插入或取出导线。此时推杆可在前述的扇形缺口空间内自由来回转动；（3）向上述操作的反方向转动推杆自由转过一定的角度后，稍加用力即可轻松推动凸轮使其离开限位挡墙；当凸轮越过稳态临界点后，弹片瞬间回弹并推动凸轮而对凸轮产生巨大冲击，锁线孔随之闭合或锁紧导线；凸轮的冲击经过扇形缺口空间时因阻尼和缓冲而减小，由凸轮传递到推杆上的冲击也因此大大减缓，从而避免使操作者的手指受到伤害；凸轮在接触对侧的阻尼挡墙后停止转动即完成一个完整的操作过程。
