Description

一种钢丝绳自锁式紧固件 技术领域
本发明涉及绳索装置技术领域，尤其涉及一种钢丝绳自锁式紧固件。
背景技术
钢丝绳扣也称钢丝绳卡子，主要用于钢丝绳的临时连接或钢丝绳穿绕连接环后的固定，它是起重吊装作业、悬挑脚手架分担荷载及物料提升机揽风绳中应用最广的钢丝绳夹具。
最常用的钢丝绳卡子为骑马式U型卡扣，但由于该种卡扣的单个强度不高，所以实际应用中，一个点位的固定就需要安装多个卡扣，同时由于单个卡扣就有两个螺丝，安装复杂且易造成应力集中，对钢丝绳有损伤。
发明内容
本发明的目的在于提供一种钢丝绳自锁式紧固件，提高钢丝绳的连接强度，减小应力损伤。
为了实现上述目的，本发明的技术方案如下：
一种钢丝绳自锁式紧固件，包括两端开口且中空的壳套，壳套内设有转轴，转轴上固定有椭圆形的锁止轮，所述锁止轮垂直于转轴的两侧与壳套内壁之间形成安装通道。
进一步的，所述锁止轮为齿轮。
进一步的，所述转轴的一端穿出壳套并固定有把手。
本发明的优点在于：
1.利用椭圆形锁止轮作为锁止结构，结构简单可靠，摩擦力分布均匀，不易损伤钢丝绳；
2.具有自锁止效果，钢丝绳越拉越紧，安全可靠；
3.采用半封闭结构的壳套，保证内部结构能长期使用不易损坏；
4.操作简单易学，一体式结构不易丢失零件，具有广泛的推广应用价值。
附图说明
图1为实施例中钢丝绳穿入其中一个安装通道时的状态示意图；
图2为实施例中钢丝绳穿入两个安装通道时的状态示意图；
图3为图2中锁止轮转动夹紧钢丝绳时的状态示意图；
图4为图3另一视角的状态示意图；
标号说明
壳套1，转轴2，锁止轮3，安装通道4，钢丝绳5，把手6。
具体实施方式
以下结合实施例对本发明作进一步详细描述。
本发明提出一种钢丝绳自锁式紧固件，包括两端开口且中空的壳套1，壳套1的两个开口端便于钢丝绳5的穿入和穿出，壳套1内沿钢丝绳5的穿入方向依次设有两根转轴2，两根转轴2上均固定有椭圆形的锁止轮3，所述锁止轮3垂直于转轴2的两侧与壳套1内壁之间形成安装通道4，锁止轮3平行于转轴2的两侧与壳套1内壁之间间隙配合。
该紧固件的使用如图1至4所示：
步骤一：如图1所示，此时壳套1内椭圆形的锁止轮3处于竖直状态，两个安装通道4的口径大于钢丝绳5的直径，将钢丝绳5从左侧的安装通道4下端穿入，上端穿出，穿出后绕过拉结系吊点再穿入右侧的安装通道4，如图2所示，为钢丝绳5穿过两个安装通道4时的状态示意图；
步骤二：如图3所示，将处于竖直状态的锁止轮3偏转，偏转后，安装通道4的口径小于钢丝绳5的直径，即锁止轮3的外周顶压两侧的钢丝绳5；
步骤三：如图4所示，下拉钢丝绳5，由于摩擦力作用，处于偏转状态的锁止轮3会进一步偏转，导致锁止轮3顶压钢丝绳5的力度加大，最终达到锁止作用，并且可以达到越拉越紧的效果。
由于安装通道4内的钢丝绳5被顶压时，钢丝绳5与壳套1内壁之间的作用面较大，相对于现有技术的骑马式U型卡扣来说，可以大幅减小钢丝绳5受到的应力，不易损伤钢丝绳5。
为便于锁止轮3的偏转，本实施例转轴2的一端穿出壳套1并固定有把手6。
为增加锁止轮3与钢丝绳5之间的摩擦力，本实施例的锁止轮3为齿轮。
上述实施例仅用于解释说明本发明的构思，而非对本发明权利保护的限定，凡利用此构思对本发明进行非实质性的改动，均应落入本发明的保护范围。
