Description

拉力试验夹
技术领域
本实用新型涉及一种夹子,特别涉及一种拉力试验夹。
背景技术
在实验室中,在对某个装置进行拉力测试时,都需要用到夹子,传统的夹子夹持力差,容易滑脱,且难以控制夹持力。
实用新型内容
【1】要解决的技术问题
本实用新型要解决的技术问题是提供一种可以控制夹持力且夹持稳定的拉力试验夹。
【2】解决问题的技术方案
本实用新型提供一种拉力试验夹,包括底座1、千分表8和拧紧螺栓9,所述底座1顶部设有吊环2,所述底座1两端分别铰接有左夹片6和右夹片5,所述左夹片6的侧壁设有螺纹孔,所述右夹片5的侧壁设有通孔,所述通孔与所述螺纹孔同轴,所述拧紧螺栓9一端配合安装在所述螺纹孔内,所述拧紧螺栓9另一端穿过所述通孔,所述拧紧螺栓9的端部设有旋钮4,所述旋钮4的端面抵住所述右夹片5的侧壁,所述千分表8安装在所述左夹片6侧壁,所述千分表8的触头抵住所述右夹片5的内壁。
进一步的,所述左夹片6和右夹片5之间设有弹簧3,所述弹簧3套设在所述拧紧螺栓9上。
进一步的,所述左夹片6和右夹片5的接触面上设有锯齿。
【3】有益效果
本实用新型拉力试验夹,通过调节旋钮来调节左右夹片的夹持力,通过千分表来直观的了解夹持力大小,当两夹片松动时,也可直观的从千分表看出,避免因拧紧螺栓松动造成夹持力变小而滑脱;两夹持片的接触面上设有锯齿,增大里表面摩擦力,从而提高了整体夹持力;本实用新型拉力试验夹,夹持力可调,夹持稳定,安全系数高。
附图说明
图1为本实用新型拉力试验夹的结构示意图。
具体实施方式
下面结合附图,详细介绍本实用新型实施例。
参阅图1,本实用新型提供一种拉力试验夹,包括底座1、千分表8和拧紧螺栓9,底座1顶部设有吊环2,底座1两端分别铰接有左夹片6和右夹片5,左夹片6的侧壁设有螺纹孔,右夹片5的侧壁设有通孔,该通孔与螺纹孔同轴,拧紧螺栓9一端配合安装在螺纹孔内,另一端穿过该通孔,拧紧螺栓9的端部设有旋钮4,该旋钮4的端面抵住右夹片5的侧壁,旋转旋钮4时,在螺纹的拉力下使左夹片向右夹片靠拢,千分表8安装在左夹片6侧壁,且该千分表8的触头抵住右夹片5的内壁;本实施例中,左夹片6和右夹片5之间设有弹簧3,该弹簧3套设在所述拧紧螺栓9上;为了防止夹持时滑脱,在左夹片6和右夹片5的接触面上设有锯齿。
本实用新型拉力试验夹,通过调节旋钮来调节左右夹片的夹持力,通过千分表来直观的了解夹持力大小,当两夹片松动时,也可直观的从千分表看出,避免因拧紧螺栓松动造成夹持力变小而滑脱;两夹持片的接触面上设有锯齿,增大里表面摩擦力,从而提高了整体夹持力;本实用新型拉力试验夹,夹持力可调,夹持稳定,安全系数高。
