录波仪正常使用时,无需利用翻转机构5进行翻转操作,将录波仪保护在防护槽11内,并通过滤波器能够起到抗磁场干扰的目的,以便于录波仪的正常使用,同时,将录波仪安装在防护槽11内,可对录波仪起到防护的作用,避免录波仪损坏。
需要操作录波仪时,向上翻转上盖51,可带动安装靠板53围绕转动点同步翻转,将录波仪从防护槽11的内部途经沉降式翻转孔12的内部转动至防护框1的上部,便于工作人员对录波仪进行操作。
上盖51的底端固定设有用于密封沉降式翻转孔12开口的封堵块52,封堵块52的四周侧壁均设有与沉降式翻转孔12内部侧壁的密封垫55,上盖51盖合在沉降式翻转孔12的开口处时,利用封堵块52封堵住沉降式翻转孔12,密封垫55可增强封堵块52封堵时的密封性,从而避免外部空气中的灰尘落在录波仪上,保证录波仪能够正常使用。
防护槽11内设有推拉机构2,推拉机构2包括推拉板21,推拉板21的侧壁设有用于密封防护槽11开口的橡胶座23,橡胶座23可封堵住防护槽11的开口,确保录波仪位于防护槽11内部的密封性,避免外部空气中的灰尘落在录波仪上。
推拉板21侧壁底端固定设有延伸至防护槽11内部的拉杆24,推拉板21可通过拉杆24沿着防护槽11内部水平抽拉,拉杆24的上端远离推拉板21的一端固定设有用于顶起安装靠板53的顶板26,顶板26跟随拉杆24水平移动而同步移动。
顶板26向外移动时,可推动安装靠板53以及上盖51围绕转动点位置向上翻转,安装在安装靠板53的录波仪同步翻转,将录波仪从防护槽11的内部途经沉降式翻转孔12的内部转动至防护框1的上部,便于工作人员对录波仪进行操作。
现有技术中采用单个存放盒放置录波仪,虽然能够对录波仪起到保护作用,需要人为拿取录波仪,操作不便,将录波仪取出使用以及将录波仪收纳起避免录波仪表面粘附灰尘的操作方式不便利。
为了解决如何确保翻转机构5与推拉机构2同步联动的问题,顶板26的顶端通过连接块设有球型转动块27,球型转动块27的外壁转动卡接有球型座28,球型座28外壁固定设有第一T型滑块29,安装靠板53靠近顶板26的一侧侧壁开设有与第一T型滑块29滑动的第一T型滑槽56,顶板26水平移动,带动球型座28水平移动,球型座28转动套在球型转动块27的外部,随着球型转动块27的水平移动,球型座28可通过第一T型滑块29沿着安装靠板53的第一T型滑槽56内部滑动,滑动的同时可将安装靠板53带动上盖51围绕转动点翻转,这样可通过推拉机构2操作翻转机构5向上或者向下翻转。
防护框1的下方设有支撑机构3,支撑机构3包括支撑柱31和底板32,支撑柱31固定设置在防护框1的底端,支撑柱31垂直安装在底板32的上端,利用底板32支撑起支撑柱31,利用支撑柱31腾空架起防护框1,便于防护框1的正常防护使用。
现有技术不采用任何支撑方式对防护框1进行支撑,只是将防护框1搬运至使用位置使用,很是不便,所以采用支撑机构3对防护框1进行支撑,且便于对防护框1进行移动,方便使用录波仪。
底板32的底端安装有刹车万向轮33,利用刹车万向轮33便于移动整体结构。
实施例二
请参阅图2和图4,在实施例1的基础上做了进一步改进:
另外,安装靠板53靠近顶板26的一侧侧壁设有斜面,斜面的倾斜角度在15-30范围内,可根据使用需求选择任意倾斜角度,第一T型滑块29沿着开设在斜面上的第一T型滑槽56内部滑动,当第一T型滑块29滑动至第一T型滑槽56的内部远离转动位置的一端,这样可将安装靠板53顶至水平状态,安装在安装槽54的录波仪能够保持水平状态,便于工作人员操作录波仪。
为了解决如何确保拉杆24水平拉动时的稳定性的问题,拉杆24的底端远离推拉板21的一侧固定有第二T型滑块25,防护槽11内部底端开设有用于第二T型滑块25滑动卡接的第二T型滑槽14,拉杆24水平拉动时,利用第二T型滑块25沿着第二T型滑槽14内部水平滑动,有助于增强拉杆24水平拉动时的稳定性。
另外,推拉板21远离拉杆24的一侧侧壁固定设有把手22,利用把手22便于拉动推拉机构2,省时省力。
实施例三
请参阅图2和图5,在实施例2的基础上做了进一步改进:
防护槽11远离开口的一侧侧壁开设有收纳槽13,收纳槽13的内部设有配重机构4,利用配重机构4可避免安装在安装槽54内的录波仪在防护槽11内晃动,不影响录波仪的正常使用。
现有技术中大多采用弹簧或者弹性件缓冲录波仪受到的振动力,但是弹簧以及弹性件自身弹性势能存在,会带动录波仪频繁震动,无法抵消掉震动力,影响录波仪的精确使用,因此采用配重机构4来代替弹簧或者弹性件对录波仪进行防震保护。
配重机构4包括第一铰接杆41、第二铰接杆42和配重块43,第一铰接杆41一端铰接在收纳槽13的内部顶部侧壁,第二铰接杆42的一端铰接在顶板26的侧壁顶端,第一铰接杆41和第二铰接杆42的另一端分别铰接在配重块43的上端两侧,利用配重块43自身重力,可将第一铰接杆41和第二铰接杆42向下拉动,使得第一铰接杆41和第二铰接杆42分别围绕各自的转动点发生转动,可降低第一铰接杆41和第二铰接杆42之间的夹角,可将顶板26向靠近收纳槽13一侧拉动,从而带动安装靠板53围绕转动点下转至竖直状态,在无外力干扰的情况下,安装靠板53不会发生反转操作,录波仪则不会发生晃动的现象。
配重块43侧壁内嵌有磁铁块44,收纳槽13的内部侧壁内嵌有与磁铁块44相互吸附的铁片15,利用磁铁块44吸附铁片15,这样可将配重块43向收纳槽13的一侧调整,这样可有助于稳固推拉机构2,避免推拉机构2水平滑动,这样即可避免录波仪晃动。
尽管已经示出和描述了本发明的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本发明的范围由所附权利要求及其等同物限定。
