Abstract

本实用新型是一种指针式弹簧吊秤,其特点是秤 钩通过横担与弹簧、齿条连结,齿条与齿轮啮合,弹簧 一端有调校螺母,弹簧受重力的伸缩转变为齿轮上指 针的转动而指示出称量,与现有弹簧吊秤相比,具有 称量指示明显、准确、零点可调等优点。

Description

本实用新型属于称量技术领域,是一种指针式弹簧吊秤。
现有的弹簧吊秤(又称测力器)是由吊钩、秤杆、弹簧、秤套、秤钩组成,存在着刻度指示不明晰,称量不准等缺点。
本实用新型的目的是设计一种指示明显,零点可调,称量准确的指针式弹簧吊秤。
本实用新型所采取的技术措施是将现有弹簧吊秤的秤套改为表盘,表盘上标有刻度,秤钩通过横担与弹簧、齿条连结,弹簧一端设调校螺母,齿条与装有指针的齿轮啮合,弹簧受重力的变化转变为指针的转动。
结合附图及实例说明本实用新型指针式弹簧吊秤的结构特征。
附图表示本实用新型指针式弹簧吊秤的结构示意图。
参见附图,本实用新型指针式弹簧吊秤由吊钩1、表盘8、秤钩9、横担6、弹簧3、调校螺母2、齿条4、齿轮5、指针7组成。表盘8上标有重量刻度,吊钩1设在表盘8壳顶,秤钩9通过横担6与弹簧3、齿条4连结。弹簧3的一端设有调校螺母2,齿轮5与齿条4啮合,指针7装在齿轮5上,齿轮5以齿轮轴固定在表盘后壳上,构成一种指针式弹簧吊秤。
称量重量时,秤钩勾着重物,提起吊钩,弹簧受重物重力伸长,齿条向下带动齿轮转动,指针随齿轮转动指示出表盘上的读数(重量)。
本实用新型的指针式弹簧吊秤与现有的弹簧吊秤相比,具有称量指示明显,称量准确,零点可调等优点。
