Description

带防尘罩的电话机
本实用新型带防尘罩的电话机,属于电信技术的电话类。
目前使用的电话机,绝大部分无防尘保护装置,为防止灰尘污染,人们图省事盖上布块或用一纸盒一罩了事,但此举乃权宜之计,既不美观使用又不方便,为此人们动脑筋设计美观实用的防护罩,专利号ZL95236219.8的“电话机防护罩”既其中一例,它结构简单成本低,防尘效果亦佳,然而该罩与电话机分离,打电话时需用手搬开,不用时又用手将其罩上,来回搬动易丢失或摔破。
本实用新型的目的是设计一种与电话机连成一体的防尘罩,克服上述易丢失摔破的缺点,同样达到净化环境的作用。
本实用新型的技术实施方案是:带防尘罩的电话机由防尘罩及电话机组成,防尘罩为与电话机正面形状相吻合的弧形空腔,在电话机手柄安放处形成凸腔,凸腔较长侧两立面开有若干传声小孔,在手柄接线相应位置开有半圆形孔,罩子四壁为平面,左右两壁的前端注有把手凸条,截面呈锯齿形或矩形,后侧面有两个铰链放置槽。电话机机座为前低后高倾斜状长方形,为将保护罩连在电话机上,需将与罩接触的电话机座左、右、前三面边缘制成翻边形,翻边朝上或向下视电话机结构而定,并在后侧配有铰链放置槽,用活动铰链将防尘罩与电话机机体相联接。
防尘罩采用透明塑料或有机玻璃材料制作。
本实用新型由于采用了上述结构,便发挥出它的优越性,与电话机防护盒相比可省掉盒座,因而结构更简单,节约材料降低成本。与专利“电话机防护罩”相比,因与机座连在一起不会产生丢失、摔破现象,另由于与电话机吻合程度好,防尘效果更佳,本结构适宜企事业单位及普通百姓家庭使用。
下面结合附图及实施例进一步说明实用新型。
图1    I型带防尘罩电话机立体图
图2    II型带防尘罩电话机立体图
图3    B向示意图
图4    弹簧限位铰链结构图
图5    A向示意图
由图1、图2可知,带防尘罩的电话机由防尘罩(1)及电话机(4)组成,通过弹簧限位活动铰链(2)联接,图1为电话机手柄直放于左侧的I型实施例,防尘罩(1)为与电话机正面形状相同的弧形空腔,左侧成凸腔,凸腔左右两立面分别开有8个传声小孔(3),便于电话铃声的传播,前端开半圆形孔(6)便于电线穿插。防尘罩左右两壁前端注有锯齿形把手凸条(5),以增加摩擦便于防尘罩的开启。防尘罩后侧有两个铰链放置槽(8),电话机机座为前低后高倾斜状长方形与防尘罩接触的左、右、前三面边缘制成翻边形,并在后侧配有两个铰链放置槽(12)(见图5),位置与防尘罩的相对应。
防尘罩与电话机机座采用弹簧限位活动铰链(2)联结,结构见图4,它由上铰片(7)、下铰片(11)通过轴销(9)连为一体,轴销上装有螺旋扭转弹簧(10),上下铰片分别插入防尘罩和机座的铰链放置槽(8)、(12)。采用弹簧限位活动铰链的优点在于罩子开启轻便并能自动限位,图4为开启状态,当合拢时,上下铰片成一直线。
图2、图3为电话机手柄横放于后侧的II型实施例的立体图及B向示意图,结构与I型大致相同,传声小孔(3)开在凸腔前后立面,半圆孔(6)开于左侧,把手凸条(5)采用矩形截面,防尘罩与机座仍采用弹簧限位活动铰链(2)联接。
