Description

一种耳挂弹片保护体
技术领域
本发明涉及一种医疗器械配件,尤其涉及听诊器配件,具体为耳挂弹片保护体。
背景技术
现有技术中听诊器的弹片两端是直接卡在耳挂上,在使用中,弹片长期受力,因弹片淬火时过硬或长期使用疲劳等各种原因,有时会发生弹片断裂的事件,弹片发生断裂的概率为1-3%,从而导致使用者受伤。
发明内容
本发明的目的在于提供一种在弹片发生断裂时避免使用者受伤的耳挂弹片保护体。
本发明的发明目的是这样实现的:
一种耳挂弹片保护体,所述保护体是一体的;所述保护体设有一贯通的圆柱孔和一三角体孔,所述圆柱孔的底面与所述三角体孔的底面在同一平面上,且所述圆柱孔与所述三角体孔相交。
进一步地;从圆柱孔的端面向内设有环形台阶,所述环形台阶与所述保护体是一体的。
进一步地;沿所述圆柱孔轴线方向在所述圆柱孔内设有凸肋,所述凸肋与所述保护体是一体的。
本发明具有在弹片发生断裂时避免使用者受伤及美观的优点。
附图说明
图1为本发明剖面示意图
图2为图1左视示意图
图3为图1右视示意图
图4为本发明使用状态示意图
图5为本发明使用状态侧面示意图
图6为弹片示意图
图中:1圆柱孔  2三角体孔  3喇叭孔  4凸柱5端面  6环形台阶  7凸肋  8弹片  9槽  A保护体
具体实施方式
下面结合附图1、2、3、4、5对本发明做进一步的说明:
结合图1、图3可知:耳挂弹片保护体A是一体的;保护体A设有一贯通的圆柱孔1和一三角体孔2,圆柱孔1的底面3与三角孔的底面4在同一平面上,且圆柱孔1与三角体孔2相交。
进一步地;结合图1、图2可知,从圆柱孔1的端面5向内设有环形台阶6,环形台阶6与保护体A是一体的。
进一步地;结合图2可知,沿圆柱孔1轴线方向在圆柱孔1内设有凸肋7,凸肋7与保护体A是一体的。
结合图4、图5、图6可知:使用时,弹片8的两端分别置于保护体A的圆柱孔1及三角体孔2中;弹片8的端面抵触环形台阶6,从而固定弹片8在保护体内的深度;
弹片8的端部为C型的管,管的开口端为槽9,其中凸肋7置于C型管的槽9内,从而可固定弹片8,使其不在保护体A内转动。
因保护体A是由弹性体材料制成,它具有很好的延伸性,使用时只要从耳挂管的一端穿入,沿耳挂管穿至弹片保护处作上下左右移动,使保护体的内腔和弹片的外廓吻合即可。
耳挂弹片在安装此保护体A后可以有效杜绝弹片在瞬间断裂时对使用者造成的伤害,减少使用者在使用时的顾虑,同时装有此保护体A的耳挂管仍可以任意调整角度方便使用者使用,其次保护体A和导音管连接处采用内嵌式配合克服了其连接处存在的瑕疵等,从而提高了整体的美观度。
