Abstract

一种手持电动钻降噪装置,属于降噪装置,主要由橡胶制成的隔声罩固定在手持电动钻前端和带有蜂窝状消声孔的弯形圆柱消声器固定在手持电动钻尾端构成,该装置解决了手持电动钻噪声大、振动强的问题,具有降噪减振效果好,结构简单,制造方便,不改变手持电动钻原结构等优点。

Description

手持电动钻降噪装置
本实用新型属于一种降噪装置。
目前工业及日常生活使用的手持电动钻,由于撞击摩擦等原因产生较强的振动,产生很大噪声,这些噪声、振动对人身造成一定的损害,长期使用者,会产生头痛、头晕、恶心呕吐,甚至对人的心脏产生损害,诱发其他疾病。现在使用的手持电动钻,基本没有降噪减振装置。
本实用新型的目的,是研制一种手持电动钻降噪、减振装置,以改善手持电动钻的工作状况,减轻振动和噪声对人身的危害。
本实用新型的基本构思;在手持电动钻头部位安装一个由橡胶做成的隔声罩,隔声罩的圆形腔口直径可按工作状况的要求分大小不同种类,在手持电动钻的尾端,安装一个消声器,消声器由截面为圆形蜂窝状的弯头式铝合金铸件,该消声器经胶垫与手持电动钻尾端联接。
本实用新型的优点,是可有效降低噪声减振效果明显,可使实际噪声降至15分贝左右,而且结构简单,制造方便,不改变现有手持电动钻的结构。
附图中1是隔声罩腔口,2是隔声罩,3是隔声罩固定端,4是固定钢夹,5是消声器固定耳,6是消声器,7是蜂窝状消声孔,8是阻尼层,9是中立轴,10是基板。
下面是本实用新型的一个实施例:
隔声罩腔口1为圆形,与隔声罩固定端3为一体呈碗状组成隔声罩2,套接在手持电动钻的前端,圆形腔口1的直径大于隔声罩固定端3的圆形直径,经过固定钢夹4固定夹紧在手持电动钻上,隔声罩的壁中基板10为乙烯基蛙橡胶,中立轴9用氯丁橡胶,阻尼层为玻璃纤维,三者胶粘一体。消声器固定耳5与手持电动钻的尾端用于固定散热片的螺栓联接,带有弯度的圆柱体消声器6上圆形截面上设置数个蜂窝状消声孔7,消声器6由铝合金铸造成为弯形圆柱体,在该圆柱体中间弯曲成直角。

Claims (3)

1、一种手持电动钻降噪装置,其特征是隔声罩套接在手持电动钻前端,经固定钢夹联连手持电动钻前端,消声器经手持电动钻尾端散热片的螺栓联接手持电动钻。
2、根据权利要求1所述的手持电动钻降噪装置,其特征是隔声罩由隔声罩圆形腔口直径大于隔声罩固定端的圆形直径的碗状橡胶体组成。
3、根据权利要求1所述的手持电动钻降噪装置,其特征是消声器的弯形圆柱的截面为圆形蜂窝状消声孔。
