Description

传送医用病人转移床用活动床的动力机构
技术领域
本发明涉及一种医疗设备。
背景技术
如专利申请CN201911062014.5所公开的，传送医用病人转移床用活动床的动力机构包括设置在床架上的电机、由电机通过传动机构（传动轮/传动带式传动机构或者链轮/链条式传动机构）带动的转动设置在床架上的丝杆、旋接在丝杆上的螺母，螺母与活动床架连接。采用丝杆、螺母的方式传动，虽然，传动精度高，但是成本也相应高，而且，拆装很不方便，况且，活动床的移动也不需要高的传送精度，另外，动力机构与活动床的其他传动机构（如使活动床的床上的皮带移动的传动机构）是独立的，相互没有联系，多种动力传动机构独立设置，也导致这个产品的结构复杂，成本高。
发明内容
本发明的发明目的在于提供一种制造成本低、拆装方便的传送医用病人转移床用活动床的动力机构。
本发明是这样实现的，包括设置在床架上的电机、由电机通过传动机构带动的传动光轴、变速箱、变速箱两边的传动轴、连接在传动轴端部的齿轮、设置在床架两边的齿条，传动光轴前后活动连接在变速箱的传动光轴动力输入轴孔内，两传动轴分别连接在变速箱两侧的动力输出端，变速箱连接在活动床的活动床架下面。
工作时，电机通过传动机构带动的传动光轴转动，传动光轴则带动变速箱内的主动斜齿轮转动，主动斜齿轮则带动变速箱内的被动斜齿轮转动，被动斜齿轮则带动传动轴转动，从而将传动光轴的纵向的转动转换成传动轴的横向的转动，传动轴则带动两边的齿轮同步转动，转动的齿轮则沿齿条前后滚动，带动变速箱沿传动光轴前后移动，从而带动与其固定连接在一起的活动床前后移动。由于变速箱与传动光轴、传动轴（变速箱两边的传动轴可采用一根横向穿过变速箱的轴）都可以通过穿接的方式连接在变速箱上，而齿轮只是放置在齿条上即完成装配，因此，拆装方便，而且，采用变速箱、齿轮、齿条传动，相对于丝杆和螺母的传动技术，成本低，况且，齿条、齿轮可与转移床上的带动活动床的床上的传输带移动的滚轴的齿条、齿轮共用，因此，可有效使转移床的整体结构简单。
本发明与已有技术相比，具有结构简单、制造成本低、拆装方便的优点。

如图2所示，活动床2包括设置在床架1上的由动力机构3带动左右移动的活动床架2a、设置在活动床架2a上的床2b，床2b包括设置在活动床架2a左右两边的滚轴2b1、绕在左右两边的滚轴2b1上的传输带2b2（皮带或者布带）、带动滚轴2b2转动的动力、设置在活动床架2a左右两边且位于滚轴2b1下面的下滚轴2b5、绕在下滚轴2b5上的下传输带2b6（皮带或者布带），下传输带2b6的下面前端固定在床架1上。
如图2所示，带动滚轴2b2转动的动力是动力机构3，在活动床架2a的其中一边的外侧的滚轴2b1下面是与齿条6啮合的齿轮4，齿轮4上方的活动床架2a上的滚轴2b1的轴上设置有可与齿轮4啮合的传动齿轮5，传动齿轮5沿滚轴2b1轴线滑动（滚轴2b1的轴上设置有键或者凸缘，对应键或者凸缘的传动齿轮5上设置有导槽）移动并带动滚轴2b1转动。
