Abstract

本实用新型提供一种安全带用锁扣,包括锁架、横梁和调节部件,调节部件和横梁平行地固定在锁架上,并且调节部件的卡紧面与横梁沿轴向方向相切。调节部件通过固定轴固定于锁架上,该固定轴上缠绕有弹簧,该弹簧的两端卡进所述调节部件的内槽,卡紧面沿逆时针反向的点与固定轴之间的距离逐渐增大。由于卡紧面沿逆时针反向的点与固定轴之间的距离逐渐增大,提高了安全性和耐用性。

Description

一种安全带用锁扣
技术领域
本实用新型涉及一种安全带用锁扣。
背景技术
安全带用锁扣,可以调节安全带的松紧,使得使用更舒适。一般的安全带用锁扣包括锁架、横梁和调节部件,调节部件和横梁固定在锁架上并且相切,以夹紧安全带,调节部件通过固定轴固定于锁架上,固定轴上缠绕有弹簧,弹簧的两端卡进所述调节部件的内槽。当调节部件逆时针方向运动时,卡紧面与横梁之间的距离增大,以调整安全带的松紧,使得使用舒适。但是,由于卡紧面沿逆时针反向的点与固定轴之间的距离相等,当使用时间较长,卡紧面磨损后,对安全带的固定能力减弱。
发明内容
本实用新型的目的是提供一种固定能力更强的安全带用锁扣。
本实用新型提供一种安全带用锁扣,包括锁架、横梁和调节部件,所述调节部件和横梁平行地固定在锁架上,所述调节部件的卡紧面与横梁沿轴向方向相切,该调节部件通过固定轴固定于锁架上,该固定轴上缠绕有弹簧,该弹簧的一端固定,另一端卡进调节部件的内槽,卡紧面沿逆时针反向的点与固定轴之间的距离逐渐增大。
由于本实用新型改进了卡紧面,使其沿逆时针方向的点与固定轴之间的距离逐渐增大,因此当使用时间较长,卡紧面磨损后,由于弹簧的存在,卡紧面将顺时针转动,以致新的接触位置与转动轴之间的距离增大,从而使卡紧能力进一步增强,即对安全带的固定能力增强,提高了安全性和耐用性。

具体实施方式
一种安全带用锁扣,包括锁架1、横梁2和调节部件3,调节部件3和横梁2平行地固定在锁架1上,调节部件的卡紧面7与横梁2沿轴向方向相切,调节部件3通过固定轴5固定于锁架1上,且固定轴5上缠绕有压紧的弹簧4,该弹簧4的一端固定,另一端卡进所述调节部件的内槽6,卡紧面7沿逆时针方向的点与固定轴5之间的距离逐渐增大。当调节部件3逆时针方向运动时,卡紧面与横梁之间的距离增大,以调整安全带的松紧,使得使用更方便舒适。当使用时间较长,卡紧面磨损后,由于弹簧的存在,卡紧面将顺时针转动,以致新的接触位置与转动轴之间的距离增大,从而使卡紧能力进一步增强,即对安全带的固定能力增强,提高了安全性和耐用性。
