卡扣自锁金属跳绳 技术领域
本实用新型涉及跳绳技术领域，具体为卡扣自锁金属跳绳。
背景技术
跳绳 https://baike.baidu.com/item/％E8％B7％B3％E7％BB％B3/697143是一种最佳的减肥瘦身操，有测试显示，跳10分钟，每分钟跳140次的运动效果就相当于慢跑半小时。跳绳不但可以帮你减肥瘦身，还可以让全身肌肉匀称有力，同时会让你的呼吸系统、心脏、心血管系统得到充分的锻炼。
现有的跳绳在更换绳体时有多种方式，具体为打结固定、外置螺丝锁紧、缠绕方式等；采用以上方式拆卸绳子慢，且在组装时也更加繁琐。
为此，我们提出了卡扣自锁金属跳绳以良好的解决上述弊端。
实用新型内容
本实用新型的目的在于提供卡扣自锁金属跳绳，以解决上述背景技术中提出的问题。
本实用新型的上述实用新型目的是通过以下技术方案得以实现的：

优选的，所述内部件的正面开设有两个第一销孔，且第一销孔通向内部件的背面，所述卡扣的中部朝内部件内延伸有凸出部，且凸出部对应第一销孔的位置开设有第二通孔，所述内部件与卡扣通过贯穿第一销孔和第二通孔 的销钉铰接连接。
优选的，所述锁紧装置与手柄之间设置有转动装置，所述转动装置包括与手柄连接的盖帽，且盖帽的顶端设置有轴承，所述轴承的中心固定连接有转轴，转轴的顶部设置有绳头，所述绳头通过圆环与内部件固定连接。
优选的，所述盖帽的外壁开设有对称的第二销孔，手柄的顶端伸入盖帽内，且手柄与盖帽通过贯穿第二销孔的销钉固定连接。
优选的，所述内部件的底部开设有第一通孔，绳头的侧壁开设有圆孔，所述圆环贯穿圆孔与第一通孔。
与现有技术相比，本实用新型提供了卡扣自锁金属跳绳，具备以下有益效果：
1.通过卡扣与跳绳线末端的凸起卡合锁紧，使跳绳拆装更方便；
2.通过在锁紧装置与手柄之间设置转动装置，降低跳绳时绳子与手柄之间的摩擦力。

具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部 分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
实施例：请参阅图1和图2，本实用新型提供一种技术方案：卡扣自锁金属跳绳，包括跳绳线10和连接在跳绳线10两端的手柄20，跳绳线10与手柄20之间设置有锁紧装置30，锁紧装置30与手柄20之间设置有转动装置40。
参阅图3和图4，锁紧装置30包括内部件31，内部件31为顶部呈开口的U型槽结构，内部件31的两侧设置有卡扣32；内部件31的正面开设有两个第一销孔311，且第一销孔311通向内部件31的背面，卡扣32的中部朝内部件31内延伸有凸出部321，且凸出部321对应第一销孔311的位置开设有第二通孔322，内部件31与卡扣32通过贯穿第一销孔311和第二通孔322的销钉312铰接连接；内部件31的内部中间设置有隔板图中未标出，卡扣32的内侧靠底端设置有导向杆324，且导向杆324上套设有弹簧325，弹簧325的两端分别与卡扣32和隔板相抵接；卡扣32的顶部靠内侧延伸有弯曲部323，跳绳线10的末端设置有连接头33，且连接头33的两侧设置有与弯曲部323卡合锁紧的凸起331；在连接时，按压卡扣32的外侧底部，弹簧325受力收缩，利用杠杆原理使弯曲部323向外移动，将连接头33伸入内部件31内，撤去外力，卡扣32在弹簧325的反弹力作用下回转，弯曲部323与凸起331锁紧固定；
转动装置40包括与手柄20连接的盖帽41，盖帽41为两端呈开口的圆筒状结构，盖帽41的外壁开设有对称的第二销孔411，手柄20的顶端伸入盖帽41内，且手柄20与盖帽41通过贯穿第二销孔411的销钉312固定连接；盖帽41的顶端设置有轴承42，且轴承42的中心固定连接有转轴43，转轴43的顶部设置有绳头44；内部件31的底部开设有第一通孔313，绳头44的侧壁开设有圆孔，绳头44与内部件31通过贯穿圆孔与第一通孔313的圆环45固定连接。
工作原理：在组装跳绳线10与手柄20时，按压卡扣32的外侧底部，弹簧325受力收缩，利用杠杆原理使弯曲部323向外移动，将连接头33伸入内部件31内，撤去外力，卡扣32在弹簧325的反弹力作用下回转，弯曲部323与凸起331锁紧固定，跳绳线10与20组装完成；在跳绳时，跳绳线10转动，从而带动锁紧装置30一起转动，圆环45则带动绳头44和转轴43一起转动，轴承43的设置使跳绳线10转动更加灵活。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括要素的过程、方法、物品或者设备中还存在另外的相同要素。
尽管已经示出和描述了本实用新型的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本实用新型的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本实用新型的范围由所附权利要求及其等同物限定。
